These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0055] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0056] The orientation terms involved in the embodiments of the present application, such as "upper", "lower", "side", etc., generally take the relative relationship of the orientation shown in Figure 1 as the reference, and the use of these orientation terms is only to more clearly describe the relationship between the structures and the structures, rather than to describe the absolute orientation. When the product is placed in different postures, the orientation may change. For example, "upper" and "lower" may be interchanged.

[0057] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meaning as commonly understood by those of ordinary skill in the art.

[0058] To make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the drawings.

[0059] The first aspect of the present application provides an aperture structure, such as Figure 1 , Figure 2 and Figure 3As shown, the aperture structure includes a driving assembly 1, a base 2, and vanes 3. The driving assembly 1 includes a first electromagnetic part 11, a second electromagnetic part 12, and a rotating part 13. Among them, the number of driving assemblies 1 is multiple, and each driving assembly 1 is connected to the base 2. The number of vanes 3 corresponds to that of the driving assemblies 1, and all the vanes 3 are arranged along the circumference of the base 2 to enclose a light passing hole 301. The first electromagnetic part 11 and the second electromagnetic part 12 are arranged along the circumference of the rotating part 13, and the first electromagnetic part 11 and the second electromagnetic part 12 can drive the rotating part 13 to rotate respectively. Each rotating part 13 is in transmission connection with a vane 3 to drive the vane 3 to rotate and adjust the cross-sectional area of the light passing hole 301.

[0060] It can be understood that by driving the vanes 3 to rotate, the driving assembly 1 can adjust the cross-sectional area of the light passing hole 301, and further change the light incident amount of the light passing hole 301. Each vane 3 is in transmission connection with a driving assembly 1, which can improve the controllability of the aperture structure of the present application for the rotation of the vanes 3, so as to improve the adjustment ability of the cross-sectional area of the light passing hole 301, and improve the adaptability of the light passing hole 301 to the expected light incident amount of the lens 7. By respectively driving the vanes 3 through the first electromagnetic part 11 and the second electromagnetic part 12, the driving assembly 1 can improve the rotation speed and accuracy of the vanes 3 when adjusting the cross-sectional area of the light passing hole 301, so as to improve the adjustment ability of the cross-sectional area of the light passing hole 301, and improve the adaptability of the light passing hole 301 to the expected light incident amount of the lens 7.

[0061] In the embodiment of the present application, by driving the vanes 3 to rotate, the driving assembly 1 can adjust the cross-sectional area of the light passing hole 301, and further change the light incident amount of the light passing hole 301. Exemplarily, each vane 3 can rotate around the axis of the rotating part 13 in transmission connection with it to adjust the cross-sectional area of the light passing hole 301. Among them, when each vane 3 rotates in the clockwise direction, the cross-sectional area of the light passing hole 301 increases, and when each vane 3 rotates in the counterclockwise direction, the cross-sectional area of the light passing hole 301 decreases. The vane 3 can also rotate around other axes under the transmission of the rotating part 13 to adjust the cross-sectional area of the light passing hole 301.

[0062] In the embodiment of the present application, each vane 3 is in transmission connection with a driving assembly 1, which can improve the controllability of the aperture structure of the present application for the rotation of the vanes 3. It can be understood that such a setting makes the working conditions of each vane 3 relatively independent, which can reduce the interference of other vanes 3 during rotation, and thus improve the controllability of the vanes 3.

[0063] In the embodiments of the present application, the driving component 1 drives the rotating part 13 through the first electromagnetic part 11 and the second electromagnetic part 12 respectively, which can improve the rotation speed and accuracy of the blade 3 when adjusting the cross-sectional area of the light passing hole 301. It can be understood that the first electromagnetic part 11 and the second electromagnetic part 12 can generate magnetic fields, and the rotating part 13 rotates under the influence of the two magnetic fields until it reaches an equilibrium position. Since the relative positions of the rotating part 13 and the first electromagnetic part 11 and the second electromagnetic part 12 change after the rotating part 13 rotates. Specifically, the first electromagnetic part 11 and the second electromagnetic part 12 are arranged along the circumferential direction of the rotating part 13. When the blade 3 moves away from one of the first electromagnetic part 11 and the second electromagnetic part 12, it can approach the other. That is, when the magnetic field force from the first electromagnetic part 11 on the blade 3 weakens, the magnetic field force from the second electromagnetic part 12 on the blade 3 increases. In this way, it is beneficial for the rotating part 13 to obtain sufficient driving force when rotating to different angles, thereby improving its rotation speed and accuracy.

[0064] In the embodiments of the present application, the rotation direction of the rotating part 13 driven by the first electromagnetic part 11 and the rotation direction of the rotating part 13 driven by the second electromagnetic part 12 can be the same or opposite. Exemplarily, when the first electromagnetic part 11 drives the rotating part 13 to rotate in the clockwise direction, the second electromagnetic part 12 can drive the rotating part 13 to rotate in the clockwise direction.

[0065] In the embodiments of the present application, the driving component 1 can realize the driving effect on the blade 3 through the electromagnetic induction effect. Exemplarily, the driving component 1 can generate a magnetic field when powered on, and generate a driving force on the blade 3.

[0066] In the embodiments of the present application, the blade 3 is used to block part of the light so that the light mainly passes through the light passing hole 301, and it generally uses light-blocking materials.

[0067] In summary, for the aperture structure of the present application, the driving component 1 drives each blade 3 independently to improve the adjustment ability of the cross-sectional area of the light passing hole 301. At the same time, the first electromagnetic part 11 and the second electromagnetic part 12 are used to drive the blade 3 to improve the rotation speed and accuracy of the blade 3 when adjusting the cross-sectional area of the light passing hole 301, thereby improving the adaptability of the light passing hole 301 to the expected light input amount of the lens 7.

[0068] In some embodiments of the present application, such as Figure 4 and Figure 5 shown, the rotating part 13 includes a magnetic unit 131 and a rotating shaft 132. The magnetic unit 131 is connected to the rotating shaft 132, and the first electromagnetic part 11 and the second electromagnetic part 12 can drive the rotating shaft 132 to rotate through the magnetic unit 131.

[0069] It can be understood that the rotating shaft 132 can be drivingly connected to the blade 3 to drive the blade 3 to rotate and adjust the cross-sectional area of the light-passing hole 301. The magnetic unit 131 can be affected by the magnetic fields of the first electromagnetic part 11 and the second electromagnetic part 12 to generate a torque on the rotating shaft 132 to drive the rotating shaft 132 to rotate and adjust the cross-sectional area of the light-passing hole 301.

[0070] In the embodiment of the present application, the magnetic unit 131 is an integral structure and is connected to the rotating shaft 132 by means of bonding or the like.

[0071] In some embodiments of the present application, when the space of the driving assembly 1 is small and the volume of the magnetic unit 131 is large, it is easy to be attracted by the first electromagnetic part 11 or the second electromagnetic part 12 and separated from the rotating shaft 132, resulting in the failure of the driving function. As Figure 6 shown, the magnetic unit 131 includes a first magnetic part 1311 and a second magnetic part 1312. Both the first magnetic part 1311 and the second magnetic part 1312 are located outside the rotating shaft 132 and are arranged along the circumferential direction of the rotating shaft 132. Such an arrangement is beneficial to improving the driving stability of the driving assembly 1.

[0072] It can be understood that the first magnetic part 1311 and the second magnetic part 1312 can be driven by the magnetic fields of the first electromagnetic part 11 and the second electromagnetic part 12 to generate two torques with the same direction on the rotating shaft 132 to drive the rotating shaft 132 to rotate. At the same time, they can also be arranged at different positions of the rotating shaft 132, which can disperse the volume of the magnetic unit 131 to reduce the situation of separating from the rotating shaft 132 and improve the driving stability of the driving assembly 1.

[0073] In some embodiments of the present application, as Figure 6 shown, the first electromagnetic part 11 includes a first guide post 111 and a first coil 112. The first coil 112 spirally extends along the circumferential direction of the first guide post 111, and the first guide post 111 extends along the radial direction of the rotating shaft 132.

[0074] In the embodiment of the present application, the first guide post 111 can support the first coil 112, which is beneficial to the first coil 112 generating a stable magnetic field after being energized to generate a force on the magnetic unit 131 to drive the rotating shaft 132 to rotate. The first guide post 111 extends along the radial direction of the rotating shaft 132, which is beneficial to the direction of the magnetic field generated by the first coil 112 acting on the magnetic unit 131 to be close to the tangential direction of the rotating shaft 132 and improve the driving effect of the first coil 112 on the magnetic unit 131.

[0075] In some embodiments of the present application, as Figure 6As shown, the second electromagnetic part 12 includes a second guide post 121 and a second coil 122. The second coil 122 spirally extends along the circumferential direction of the second guide post 121, and the second guide post 121 extends along the radial direction of the rotating shaft 132.

[0076] In the embodiment of the present application, the second guide post 121 can support the second coil 122, which is beneficial to the second coil 122 generating a stable magnetic field after being energized, so as to generate a force on the magnetic unit 131 to drive the rotating shaft 132 to rotate. The second guide post 121 extends along the radial direction of the rotating shaft 132, which is beneficial to the direction of the magnetic field generated by the second coil 122 acting on the magnetic unit 131 to be close to the tangential direction of the rotating shaft 132, thereby improving the driving effect of the second coil 122 on the magnetic unit 131.

[0077] In some embodiments of the present application, such as Figure 6 As shown, the first electromagnetic part 11 includes a first guide post 111 and a first coil 112. The first coil 112 spirally extends along the circumferential direction of the first guide post 111, the first guide post 111 extends along the radial direction of the rotating shaft 132, the second electromagnetic part 12 includes a second guide post 121 and a second coil 122, the second coil 122 spirally extends along the circumferential direction of the second guide post 121, and the second guide post 121 extends along the radial direction of the rotating shaft 132.

[0078] In some embodiments of the present application, the driving assembly 1 is used as the structure of the driving blade 3, and it is easily damaged and fails when the aperture structure is collided. As Figure 2 and Figure 3 As shown, the base 2 has positioning grooves 201. The number of the positioning grooves 201 corresponds to the number of the driving assemblies 1, and at least a part of each driving assembly 1 is located in a positioning groove 201. This is beneficial to protecting the driving assembly 1.

[0079] It can be understood that on the one hand, the positioning groove 201 can help determine the installation position of the driving assembly 1, so that all the blades 3 can enclose the light passing hole 301 and adjust the cross-sectional area of the light passing hole 301 by rotation. On the other hand, it is beneficial for the base 2 to contact other components instead of the driving assembly 1, thereby protecting the driving assembly 1.

[0080] In some embodiments of the present application, such as Figure 4 As shown, the driving assembly 1 further includes a housing 14. The housing 14 has a receiving cavity 1401. The first electromagnetic part 11, the second electromagnetic part 12 and the rotating part 13 are all located in the receiving cavity 1401, and the outer side of the housing 14 is connected to the side wall of the positioning groove 201.

[0081] It can be understood that the housing 14 can support and protect the first electromagnetic part 11, the second electromagnetic part 12 and the rotating part 13, which is beneficial to their normal operation. The outer side of the housing 14 is in contact with the side wall of the positioning groove 201, which can reduce the relative displacement and collision between the two, thus being beneficial to the normal operation of the driving assembly 1.

[0082] In some embodiments of the present application, such as Figure 5 As shown, the housing 14 includes a first sub-housing 141 and a second sub-housing 142. An accommodation cavity 1401 is formed between the first sub-housing 141 and the second sub-housing 142. The first sub-housing 141 is attached to the side wall of the positioning groove 201, and the second sub-housing 142 covers at least a part of the opening of the positioning groove 201.

[0083] It can be understood that the first electromagnetic part 11, the second electromagnetic part 12 and the rotating part 13 can be first installed on the first sub-housing 141 or the second sub-housing 142, and then the first sub-housing 141 and the second sub-housing 142 are connected to each other so that the first electromagnetic part 11, the second electromagnetic part 12 and the rotating part 13 are located in the accommodation cavity 1401. On the one hand, this can reduce the interference of the housing 14 on the first electromagnetic part 11, the second electromagnetic part 12 and the rotating part 13, which is beneficial to improving the assembly efficiency of the driving assembly 1.

[0084] In the embodiment of the present application, the first sub-housing 141 and the second sub-housing 142 can enclose a cubic structure, and the accommodation cavity 1401 is located inside this structure.

[0085] In some embodiments of the present application, due to the light input requirement of the lens 7, the cross-sectional area of the light passing hole 301 has a certain range. Such as Figure 6 As shown, the housing 14 has a first limiting part 143, and the rotating part 13 has a second limiting part 133. The first limiting part 143 cooperates with the second limiting part 133 to limit the maximum rotatable angle of the rotating part 13.

[0086] It can be understood that through the cooperation of the first limiting part 143 and the second limiting part 133, the angle of the rotating part 13 can be restricted. Reasonably restricting the maximum rotatable angle of the rotating part 13 is beneficial to keeping the cross-sectional area of the light passing hole 301 within a relatively reasonable range, which is beneficial for the user to adjust an appropriate light input amount.

[0087] In the embodiment of the present application, the first limiting part 143 can be a protrusion, and the second limiting part 133 can be a groove. The first limiting part 143 can rotate relative to the second limiting part 133. When the first limiting part 143 contacts the second limiting part 133, the first limiting part 143 can interfere with the second limiting part 133, making the second limiting part 133 unable to rotate further, thus restricting the maximum rotation angle of the rotating part 13.

[0088] Optionally, the maximum angle by which the rotating part 13 can rotate is 10°, 15° or 20°, or it can be other angles.

[0089] In some embodiments of the present application, as Figure 6 shown, the first limiting part 143 is a groove, the second limiting part 133 is a protrusion, the second limiting part 133 extends into the first limiting part 143, and the rotating part 13 can drive the second limiting part 133 to rotate relative to the first limiting part 143.

[0090] It can be understood that when the first limiting part 143 is in contact with the second limiting part 133, the first limiting part 143 can interfere with the second limiting part 133, making the second limiting part 133 unable to continue rotating. In this way, the maximum rotation angle of the rotating part 13 can be limited, and thus the maximum angle by which it can rotate can be restricted.

[0091] In some embodiments of the present application, the first electromagnetic part 11 and the second electromagnetic part 12 generally need to be energized to generate a magnetic field or change the intensity of the magnetic field, and the housing 14 hinders the first electromagnetic part 11 and the second electromagnetic part 12 from obtaining power. As Figure 4 shown, the housing 14 has a first electrical connection part 144, and each positioning groove 201 has a second electrical connection part 21. The first electromagnetic part 11 and the second electromagnetic part 12 are respectively electrically connected to the second electrical connection part 21 through the first electrical connection part 144. This is beneficial for the first electromagnetic part 11 and the second electromagnetic part 12 to obtain power.

[0092] It can be understood that the electrical conduction between the first electrical connection part 144 and the second electrical connection part 21 is beneficial for the base 2 to supply power to the first electrical connection part 144 through the second electrical connection part 21, and the first electromagnetic part 11 and the second electromagnetic part 12 obtain power through the first electrical connection part 144, and can generate a magnetic field to drive the rotating part 13.

[0093] In an embodiment of the present application, the first electrical connection part 144 can be a convex part, the second electrical connection part 21 can be a convex part, and the two are in contact to achieve electrical conduction. One of the first electrical connection part 144 and the second electrical connection part 21 can be a groove, and the other can be a convex part, and the two cooperate to achieve electrical conduction.

[0094] In an embodiment of the present application, the material of the first electrical connection part 144 can include conductive metal.

[0095] In an embodiment of the present application, the material of the second electrical connection part 21 can include conductive metal.

[0096] In some embodiments of the present application, the positioning groove 201 is in contact with the housing 14, such that when there is a sudden displacement in the aperture structure, such as a collision or a drop, they are prone to collide with each other, resulting in damage to the first electrical connection portion 144 and the second electrical connection portion 21. As Figure 4 shown, the aperture structure further includes a buffer portion 4, and the buffer portion 4 is located between the side wall of the positioning groove 201 and the housing 14.

[0097] It can be understood that the buffer portion 4 located between the side wall of the positioning groove 201 and the housing 14 can buffer the housing 14 when there is a sudden displacement, reduce the impact on the housing 14, so as to protect the first electromagnetic portion 11, the second electromagnetic portion 12 and the rotating portion 13 in the housing 14, which is beneficial to the normal operation of the driving assembly 1.

[0098] In some embodiments of the present application, as Figure 4 shown, the buffer portion 4 and the first electrical connection portion 144 are respectively located on opposite sides of the positioning groove 201.
