Description

Technical Field

[0002] At present, electronic devices such as mobile phones, tablet computers, and personal computers (PCs) need to maintain constant shooting quality under various brightness conditions. To achieve this goal, a variable aperture (VA) can be set on the light-entering side of the optical lens in the camera module. The aperture hole of the variable aperture can be variable in size. In a high-brightness environment, the size of the aperture hole can be reduced to allow a relatively small amount of light to enter the optical lens. In a low-brightness environment, the size of the aperture hole can be expanded to allow a relatively large amount of light to enter the optical lens. This achieves the adjustment of the amount of light entering the optical lens and ensures the shooting quality.

[0003] The variable aperture in the related technology usually adopts a complex mechanical structure to drive the shading member to move in a straight line to adjust the aperture of the aperture hole, which makes the variable aperture complex in structure and large in size, and cannot meet the needs of miniaturization and micro-miniaturization of camera modules.

[0096] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0097] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate directions or positional relationships based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0098] It should be understood that in this application, "electrical connection" can be understood as physical contact and electrical conduction between components; it can also be understood as a form of connection between different components in the circuit structure through physical lines such as printed circuit board (PCB) copper foil or wires that can transmit electrical signals. "Communication connection" can refer to electrical signal transmission, including wireless communication connection and wired communication connection. Wireless communication connection does not require a physical medium and does not belong to a connection relationship that limits the product structure. "Connection" and "connected" can both refer to a mechanical connection relationship or a physical connection relationship, that is, A is connected to B or A is connected to B, which can mean that there is a fastening component (such as screws, bolts, rivets, etc.) between A and B, or A and B are in contact with each other and A and B are difficult to separate.

[0099] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those of ordinary skill in the art.

[0100] Optical Image Stabilization (OIS) relies on the structure and movement of special lenses or photosensitive elements to minimize image instability caused by operator shaking during use.

[0101] Auto Focus: (Auto Focus, AF), uses the principle of light reflection from an object. The reflected light is received by the sensor on the camera (module), processed by a computer, and drives the electric focus device to focus.

[0102] A variable aperture is an aperture that can be adjusted as needed to control the amount of light entering the camera. Variable apertures are widely used in professional cameras. The size of this type of variable aperture is controlled by a set of blades inside the lens and can be changed manually or automatically. A larger aperture allows more light to enter the camera, making the photo brighter. It can also create a shallow depth of field effect when shooting close subjects, making the subject stand out. A smaller aperture can limit the amount of light entering the camera, making the photo darker. It can also create a deep depth of field effect when shooting distant scenes, making the entire picture clear.

[0103] Professional cameras have large lenses and a large size, and there is ample space inside to arrange complex mechanical structures to achieve variable aperture blade control. However, due to the size of electronic devices such as mobile phones, the size of mobile phone cameras and their lenses is strictly controlled, making it difficult to achieve variable aperture on mobile phone cameras.

[0104] In the related art, mobile phone cameras of low-end and mid-range electronic devices usually have a fixed aperture size, so they cannot realize the variable aperture function. Only some high-end electronic devices are equipped with variable aperture lenses, because all variable apertures of mobile phone cameras generally have problems such as complex structure and high cost.

[0105] Therefore, the present application provides a variable aperture, as well as a camera module and an electronic device using the variable aperture. The structure of the shading blades and the driving parts is simple, and the aperture adjustment is achieved by rotation. No complex mechanical structure is required and the size is small, which is conducive to the application of the variable aperture in miniaturized and micro-miniaturized camera modules.

[0106] The electronic device provided in the present application can be any of various types of computer system devices that are mobile or portable and perform wireless communication ( Figure 1 Specifically, the electronic device may be a mobile phone or a smart phone (e.g., a phone based on iPhone TM, a phone based on Android TM), a portable gaming device (e.g., Nintendo DS TM, PlayStation Portable TM, Gameboy Advance TM, iPhone TM), a laptop, a PDA, a portable Internet device, a music player, and a data storage device, other handheld devices, and headsets, etc. The electronic device may also be other wearable devices that need to be charged (e.g., a head mounted device (HMD) such as an electronic bracelet, an electronic necklace, an electronic device, or a smart watch).

[0107] The electronic device can also be any one of a plurality of electronic devices, including but not limited to cellular phones, smart phones, other wireless communication devices, personal digital assistants, audio players, other media players, music recorders, video recorders, other media recorders, radios, medical devices, vehicle transportation instruments, calculators, programmable remote controls, pagers, laptop computers, desktop computers, printers, netbook computers, personal digital assistants (PDAs), portable multimedia players (PMPs), Moving Picture Experts Group (MPEG-1 or MPEGG-2) Audio Layer 3 (MP3) players, portable medical devices, and digital cameras and combinations thereof.

[0108] In some cases, the electronic device can perform multiple functions (e.g., play music, display video, store pictures, and receive and send phone calls). If desired, the electronic device can be a device such as a cellular phone, a media player, other handheld device, a wristwatch device, a pendant device, a handset device, or other compact portable device.

[0109] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0110] On the one hand, combined with Figure 1 , 2 As shown, this embodiment provides a variable aperture 10, which includes: a first base member 1, a driving member 2 and at least one shading blade 3; the base member is provided with an aperture hole 11, at least one shading blade 3 is rotatably connected to the base member, and the driving member 2 and at least one shading blade 3 are movably connected.

[0111] The variable aperture 10 is configured such that when the driving member 2 moves relative to the base member, the driving member 2 drives at least one shading blade 3 to rotate relative to the base member, so that at least part of the at least one shading blade 3 enters or exits the aperture hole 11, thereby changing the effective light-entering area of ​​the aperture hole 11. The effective light-entering area is the area of ​​the aperture hole 11 that is not blocked by the shading blade 3. When the area of ​​this part of the aperture hole 11 is larger, more light enters the aperture hole 11. When the area of ​​this part of the aperture hole 11 is smaller, less light enters the aperture hole 11, thereby achieving the adjustment of the aperture.

[0112] In the variable aperture 10 of the present embodiment, the shading blade 3 is rotatably connected to the base member, and the driving member 2 drives the shading blade 3 to rotate relative to the base member, so that at least part of the shading blade 3 rotates into or out of the aperture hole 11, changing the effective light-incoming area of ​​the aperture hole 11, thereby achieving adjustment of the aperture size. The shading blade 3 and the driving member 2 have a simple structure, rely on rotation to achieve aperture adjustment, do not require a complex mechanical structure, and have a small size, which is conducive to the application of the variable aperture 10 in miniaturized and micro-miniaturized camera modules.

[0113] In this embodiment, at least one shading blade 3 is rotatably connected to the base member. Compared with other movable connection modes (such as sliding), the rotatable connection has better impact resistance and can improve the working reliability of the variable aperture 10.

[0114] Exemplarily, the number of the shading blades 3 is, for example, one, two, three, etc. Optionally, the number of the shading blades 3 is two.

[0115] In another exemplary embodiment, the driving member 2 is rotatably connected to the base member, and the driving member 2 can rotate relative to the base member. When the driving member 2 rotates relative to the base member, the driving member 2 drives the base member to rotate relative to the base member. Therefore, the connection between the driving member 2 and the base member is a rotational connection, which has good impact resistance and can improve the working reliability of the variable aperture 10.

[0116] In some possible implementations, the shading blade 3 is located on the light-incoming side of the aperture 11, and the shading blade 3 is made of lightweight non-light-transmitting material. When at least part of the shading blade 3 enters the aperture 11, no light will enter the part of the aperture 11 blocked by the shading blade 3.

[0117] Combination Figure 1 , 2 As shown, in some embodiments, at least one shading blade 3 is provided with a blade hinge portion 301 and a blade guide portion 302; an aperture hinge portion 12 is provided on the base member on the peripheral side of the aperture hole 11, and the driving member 2 is provided with an aperture guide portion 21; the blade hinge portion 301 is rotatably connected to the aperture hinge portion 12, and the blade guide portion 302 is movably connected to the aperture guide portion 21.

[0118] The shading blade 3 realizes the rotational connection between the shading blade 3 and the base member by the hinged connection between the blade hinge part 301 and the aperture hinge part 12, wherein the aperture hinge part 12 is located on the peripheral side of the aperture hole 11, that is, close to the aperture hole 11, and the shading blade 3 is hinged at a position close to the aperture hole 11, and the effective working area of ​​the shading blade 3 (that is, the ability to rotate into the aperture hole 11) is larger, and only a small area needs to be reserved as a hinged part, and the rest of the part can be used as an effective working area. The effective working area of ​​a single shading blade 3 is larger, which is conducive to reducing the number of shading blades 3 used, and the weight of the entire variable aperture 10 is lighter. The power of the shading blade 3 is realized by the movable connection between the blade guide part 302 and the aperture guide part 21, and the driving structure of the shading blade 3 is simpler and more efficient.

[0119] Combination Figure 1 , 2 As shown, in some embodiments, one of the blade hinge 301 and the aperture hinge 12 is a hinge hole, and the other of the blade hinge 301 and the aperture hinge 12 is a hinge axis; exemplarily, the blade hinge 301 is a hinge hole, and the aperture hinge 12 is a hinge axis; or, the blade hinge 301 is a hinge axis, and the aperture hinge 12 is a hinge hole.

[0120] The rotation axes of the blade hinge 301 and the aperture hinge 12 are parallel to the axis of the aperture hole 11, so that at least one light shielding blade 3 rotates in a plane perpendicular to the axis of the aperture hole 11. Thus, the light shielding blade 3 can rotate in a direction perpendicular to the axis of the aperture hole 11, enter or exit the aperture hole 11, and has a more stable rotation characteristic.

[0121] Combination Figure 1 , 2 As shown, in some embodiments, one of the blade guide portion 302 and the aperture guide portion 21 is a guide groove, and the other of the blade guide portion 302 and the aperture guide portion 21 is a guide protrusion. Exemplarily, the blade guide portion 302 is a guide groove, and the aperture guide portion 21 is a guide protrusion; or, the blade guide portion 302 is a guide protrusion, and the aperture guide portion 21 is a guide groove. By using the cooperation of the guide groove and the guide protrusion, the power transmission between the driving member 2 and the shading blade 3 can be realized, so that the shading blade 3 rotates relative to the base member.

[0122] Exemplarily, the guide groove includes but is not limited to a straight groove, a wire-removing groove, etc. The guide protrusion can be a protrusion structure, or a pin shaft, a pin, or the like.

[0123] Combination Figure 3 , 4As shown, in some embodiments, the shading blade 3 includes a first shading blade 31 and a second shading blade 32; the first shading blade 31 and the second shading blade 32 are respectively rotatably connected to the base member, and the first shading blade 31 and the second shading blade 32 are respectively located at different positions around the aperture hole 11.

[0124] The first light-shielding blade 31 and the second light-shielding blade 32 are respectively movably connected to the driving member 2, and the driving member 2 can respectively drive the first light-shielding blade 31 and the second light-shielding blade 32 to rotate relative to the base member, so that at least parts of the first light-shielding blade 31 and the second light-shielding blade 32 enter or exit the aperture hole 11 synchronously.

[0125] The variable aperture 10 of this embodiment includes a first shading blade 31 and a second shading blade 32. The two shading blades 3 are movably connected to the driving member 2 respectively. When the driving member 2 is active, the two shading blades 3 can synchronously enter or exit the aperture hole 11. When the two shading blades 3 synchronously enter the aperture hole 11, the effective light-incoming area of ​​the aperture hole 11 is reduced, and the aperture is reduced. When the two shading blades 3 synchronously exit the aperture hole 11, the effective light-incoming area of ​​the aperture hole 11 is increased, and the aperture is increased.

[0126] The double blades can ensure that the aperture adjustment efficiency and adjustment range are improved under the premise of low weight. The variable aperture 10 has a simpler structure and a smaller size, especially the axial size along the aperture hole 11 is smaller, which is suitable for application scenarios such as miniaturized and small mobile phone cameras.

[0127] Combination Figure 3 , 4 As shown in FIG. 5 , in some embodiments, the first shading blade 31 has a first concave portion 311 on one side facing the axis of the aperture hole 11 , and the second shading blade 32 has a second concave portion 321 on one side facing the axis of the aperture hole 11 .

[0128] The first concave portion 311 and the second concave portion 321 are positioned relative to each other. When the first shading blade 31 and the second shading blade 32 enter the aperture hole 11 synchronously, the first concave portion 311 and the second concave portion 321 can be spliced ​​mouth to mouth, and the space enclosed by the first concave portion 311 and the second concave portion 321 forms a first target aperture 1001.

[0129] Since the first light-shielding blade 31 and the second light-shielding blade 32 are in rotational motion, in order to ensure that the target aperture can be formed after the first light-shielding blade 31 and the second light-shielding blade 32 enter the aperture hole 11, a first concave portion 311 and a second concave portion 321 are respectively provided on the first light-shielding blade 31 and the second light-shielding blade 32. When the first concave portion 311 and the second concave portion 321 are connected, they can surround the first target aperture 1001, thereby realizing the adjustment of the aperture.

[0130] In some possible implementations, the first concave portion 311 and the second concave portion 321 are respectively circular concave portions, and the movement trajectories of the centers of the first concave portion 311 and the second concave portion 321 just pass through the axis of the aperture hole 11, so that the axis of the first target aperture 1001 can coincide with the axis of the aperture hole 11.

[0131] Combination Figure 3 , 4 As shown in , 6 , in some embodiments, the first light-shielding blade 31 inside the first concave portion 311 is further provided with a third concave portion 312 , and the second light-shielding blade 32 inside the second concave portion 321 is further provided with a fourth concave portion 322 .

[0132] The third concave portion 312 and the fourth concave portion 322 are positioned relative to each other. When the first shading blade 31 and the second shading blade 32 enter the aperture hole 11 synchronously, the third concave portion 312 and the fourth concave portion 322 can be spliced ​​mouth to mouth, and the space enclosed by the third concave portion 312 and the fourth concave portion 322 forms a second target aperture 1002.

[0133] By arranging the third concave portion 312 on the inner side of the first concave portion 311 and the fourth concave portion 322 on the inner side of the second concave portion 321, it is possible to further rotate the first shading blade 31 and the second shading blade 32 inward on the basis of the first target aperture 1001, and utilize the third concave portion 312 and the fourth concave portion 322 to form a second target aperture 1002 with a smaller aperture. The adjustment of the first target aperture 1001 and the second target aperture 1002 only requires controlling the rotation angle of the first shading blade 31 and the second shading blade 32 entering the aperture hole 11, which is simple to control and has high working reliability.

[0134] It should be noted that the present application uses the first target aperture 1001 and the second target aperture 1002 as an exemplary description, and does not limit the variable aperture 10 of the present application to only include the first target aperture 1001 and the second target aperture 1002. The number and aperture size of the target apertures can be reasonably designed to generate a third target aperture, a fourth target aperture, etc., and the present application does not limit this.

[0135] In some possible implementations, the third concave portion 312 and the fourth concave portion 322 are respectively circular concave portions, and the movement trajectory lines of the center of the third concave portion 312 and the center of the fourth concave portion 322 just pass through the axis of the aperture hole 11, so that the axis of the second target aperture 1002 can coincide with the axis of the aperture hole 11.

[0136] In some embodiments, the axes of the first target aperture 1001, the second target aperture 1002 and the aperture hole 11 coincide with each other. When the axes of the first target aperture 1001, the second target aperture 1002 and the aperture hole 11 coincide with each other, no matter whether the aperture is larger or smaller, the light entering the aperture hole 11 can be concentrated around the axis of the aperture hole 11, which is beneficial to improving the imaging quality and imaging efficiency of the photosensitive component in the camera module.

[0137] Combination Figure 3 , 4 As shown, in some embodiments, the first light-shielding blade 31 is provided with a first blade hinge portion 313 and a first blade guide portion 314 , and the second light-shielding blade 32 is provided with a second blade hinge portion 323 and a second blade guide portion 324 .

[0138] An aperture hinge 12 is provided on the base member on the peripheral side of the aperture hole 11, and an aperture guide 21 is provided on the driving member 2; the first blade hinge 313 and the second blade hinge 323 are respectively rotatably connected to the aperture hinge 12, and the first blade guide 314 and the second blade guide 324 are respectively movably connected to the aperture guide 21; when the driving member 2 moves relative to the base member, the aperture guide 21 can respectively drive the first shading blade 31 and the second shading blade 32 to rotate in opposite directions around the aperture hinge 12.

[0139] The variable aperture 10 of this embodiment adopts a double-blade design. In order to further simplify the structure, the first light-shielding blade 31 and the second light-shielding blade 32 share an aperture hinge portion 12 and an aperture guide portion 21. A driving member 2 is used to drive the first light-shielding blade 31 and the second light-shielding blade 32 to rotate synchronously in opposite directions, so that the two light-shielding blades 3 can synchronously enter or exit the aperture hole 11.

[0140] Taking the aperture guide part 21 as the guide protrusion and the blade guide part 302 as the guide groove as an example, the rotation direction of the shading blade 3 is determined by the relative position of the aperture guide part 21 and the aperture hinge part 12, as well as the movement direction of the aperture guide part 21 and the extension direction of the blade guide part 302. By reasonably designing the relative position of the aperture guide part 21 and the aperture hinge part 12, as well as the movement direction of the aperture guide part 21 and the extension direction of the blade guide part 302, the driving part 2 can drive the first shading blade 31 and the second shading blade 32 to rotate synchronously in the opposite direction.

[0141] In some possible implementations, the aperture guide portion 21 is closer to the aperture hole 11 than the aperture hinge portion 12, that is, the distance between the aperture hole 11 and the aperture guide portion 21 is smaller than the distance between the aperture hole 11 and the aperture hinge portion 12. The first blade guide portion 314 and the second blade guide portion 324 are both guide grooves, and extend in opposite directions, so that when the driving member 2 drives the aperture guide portion 21 to move in a certain direction, the first light shielding blade 31 and the second light shielding blade 32 rotate in opposite directions.

[0142] Combination Figure 7 As shown, in some embodiments, the first light-shielding blade 31 is provided with a first blade hinge portion 313 and a first blade guide portion 314 , and the second light-shielding blade 32 is provided with a second blade hinge portion 323 and a second blade guide portion 324 .

[0143] A first aperture hinge 121 and a second aperture hinge 122 are provided on the base member on the peripheral side of the aperture hole 11, and the first aperture hinge 121 and the second aperture hinge 122 are spaced apart along the circumference of the aperture hole 11; the driving member 2 is provided with a first aperture guide 211 and a second aperture guide 212; the first blade hinge 313 is rotatably connected to the first aperture hinge 121, the second blade hinge 323 is rotatably connected to the second aperture hinge 122, the first blade guide 314 is movably connected to the first aperture guide 211, and the second blade guide 324 is movably connected to the second aperture guide 212.

[0144] When the driving member 2 moves relative to the base member, the first aperture guide portion 211 can drive the first light-shielding blade 31 to rotate around the first aperture hinge portion 121, and the second aperture guide portion 212 can drive the second light-shielding blade 32 to rotate around the second aperture hinge portion 122, and the rotation directions of the first light-shielding blade 31 and the second light-shielding blade 32 are opposite.

[0145] Based on the concept of the present application, the first shading blade 31 and the second shading blade 32 can also be arranged in a hinged manner with different positions. The two shading blades 3 are separately rotatably connected to the base member and separately movably connected to the driving member 2, and the two shading blades 3 can also be used to adjust the aperture.

[0146] Combination Figure 3 , 4 As shown, in some embodiments, the driving member 2 includes a rotating connection portion 22 and an actuating connection portion 23; the rotating connection portion 22 is an annular structure, the rotating connection portion 22 is connected to the base member, and at least one shading blade 3 is movably connected to the rotating connection portion 22; the rotating connection portion 22 coincides with the axis of the aperture hole 11, and the rotating connection portion 22 can rotate around the axis of the aperture hole 11 relative to the base member; the actuating connection portion 23 is connected to the rotating connection portion 22, and the actuating connection portion 23 is used to provide a rotational torque for the rotating connection portion 22.

[0147] In order to solve the assembly position of the driving member 2, the driving member 2 is designed to be composed of two parts: a rotating connection part 22 and an actuating connection part 23. The rotating connection part 22 is designed to be annular and arranged to rotate coaxially with the aperture hole 11, so that the driving member 2 can rotate around the axis of the aperture hole 11, and the shading blades 3 are movably connected to the rotating connection part 22. The self-movement of the driving member 2 and the driving stability of the shading blades 3 are greatly improved, and it also has corresponding impact resistance. The actuating connection part 23 can connect the driving structure to provide a rotational torque for the rotating connection part 22.

[0148] Combination Figure 3 , 4 As shown, in some embodiments, an inwardly recessed annular step 13 is provided on the base member on the peripheral side of the aperture hole 11, and the rotating connection portion 22 is located on the annular step 13. The rotating connection portion 22 is assembled through the annular step 13, which has the advantages of simple structure and high assembly connection reliability, and is also conducive to reducing the axial size of the variable aperture 10, which is conducive to the application of the variable aperture 10 in micro and small camera modules.

[0149] Combination Figure 3 , 4 As shown, in some embodiments, at least three first balls 14 are provided between the annular step 13 and the rotating connection portion 22 , and the at least three first balls 14 are used to achieve rotational movement between the rotating connection portion 22 and the first base member 1 through rolling friction.

[0150] At least three first balls 14 are used to improve the sliding friction between the rotating connection part 22 and the annular step 13 into rolling friction, which is beneficial to reducing the friction resistance between the rotating connection part 22 and the annular step 13, improving the rotation performance of the driving member 2, and improving the adjustment performance of the variable aperture 10.

[0151] Combination Figure 3 , 4 As shown, in some embodiments, the first base member 1 is further provided with an avoidance opening 15, which is connected to the annular step 13, and the actuating connection part 23 extends to the outside of the first base member 1 through the avoidance opening 15; the size of the avoidance opening 15 is larger than the size of the actuating connection part 23, so that the actuating connection part 23 can rotate in the avoidance opening 15.

[0152] The actuation connection portion 23 can be extended to the outside of the first base member 1 through the avoidance opening 15 of the first base member 1 to obtain the power input of the driving device. This makes it unnecessary for the variable aperture 10 to carry a driving device inside itself, or it can use a driving device of an adjacent structure (such as a zoom actuator, an anti-shake actuator), further simplifying the structure of the variable aperture 10.

[0153] Combination Figure 3 , 4 As shown, in some embodiments, the variable aperture 10 also includes a first drive component 4, the first drive component 4 includes a first magnet group 41 and a first coil group 42; the actuating connection part 23 is connected to the first magnet group 41 or the first coil group 42, and the magnetic field of the first magnet group 41 or the first coil group 42 is coupled.

[0154] By using the first driving component 4, the magnetic field force can be used to push the actuating connection part 23 to rotate, and the actuating connection part 23 drives the rotating connection part 22 to rotate. The aperture guide part 21 of the rotating connection part 22 cooperates with the blade guide part 302 of the shading blade 3, driving the shading blade 3 to rotate around the aperture hinge part 12, thereby realizing the adjustment of the aperture.

[0155] Exemplarily, the first magnet group 41 is located on the actuating connection part 23, and the first coil group 42 is located on other structures (such as the first base member 1, the camera module base, and other structures fixed relative to the driving member 2). Alternatively, the first coil group 42 is located on the actuating connection part 23, and the first magnet group 41 is located on other structures.

[0156] In another exemplary embodiment, the first magnet group 41 includes at least one magnet, and the first coil group 42 includes at least one energized coil.

[0157] Optionally, the first magnet group 41 includes at least two magnets, which are arranged adjacent to each other along the rotation direction of the actuating connection portion 23, and the magnetic field directions of the magnets are directions close to and away from the axis of the aperture hole 11, and the magnetic field directions of adjacent magnets are opposite. For example, the N pole of the first magnet faces the axis of the aperture hole 11, and the S pole faces away from the axis of the aperture hole 11; the N pole of the adjacent second magnet faces away from the axis of the aperture hole 11, and the S pole faces the axis of the aperture hole 11.

[0158] When a current in a certain direction is passed through the first coil group 42 corresponding to the above-mentioned two magnets to generate a magnetic field with the N pole facing the axis of the aperture hole 11, the first coil group 42 is attracted to the S pole of the first magnet and repelled from the N pole of the second magnet, so that the actuating connecting part 23 has a rotation tendency to align the first coil group 42 and the first magnet.

[0159] It should be noted that the magnetic field coupling between the first magnet group 41 and the first coil group 42 can be understood as that the magnetic field generated by the first magnet group 41 at least partially overlaps with the magnetic field generated by the first coil group 42, so that the two magnetic fields generate an attractive force or a repulsive force. Among them, the magnetic field generated by the first coil group 42 is affected by the current flowing therein, so that the interaction force between the two magnetic fields can be controlled, that is, by controlling the current of the first coil group 42, the magnetic field of the first coil group 42 can be changed, thereby adjusting the interaction force between the first magnet group 41 and the first coil group 42. When one of the two is fixed in position, the other will be pulled or pushed by the reaction force, thereby producing the desired movement effect.

[0160] Combination Figure 8 , 9 As shown, in some embodiments, the variable aperture 10 further includes a first housing 8, the first housing 8 and the first base member 1 are connected along the axial direction of the aperture hole 11, the driving member 2 and at least one shading blade 3 are located in the first housing 8, and the first housing 8 is provided with an escape hole 81 for light to pass through. The shading blade 3 and the driving member 2 are placed inside the first housing 8, which can play a role in protection and dust prevention.

[0161] On the other hand, combined Fig.10 , 11 As shown, this embodiment provides a camera module, which includes: an optical lens 20; a photosensitive component, the photosensitive component includes a circuit board and a photosensitive element, the photosensitive element is electrically connected to the circuit board, and the optical lens 20 is located on the light sensitive path of the photosensitive element; and the variable aperture 10 of the present application, wherein the variable aperture 10 is located on the light input path of the optical lens 20.

The variable aperture 10 is located on the light input path of the optical lens 20, and can adjust the amount of light input to the optical lens 20, thereby realizing the aperture adjustment of the camera module.

[0163] In some possible implementations, a printed circuit is provided on the surface of the circuit board, and the circuit board includes a printed circuit board (Printed Circuit Board, PCB), a flexible printed circuit board (Flexible Printed Circuit Board, FPC), a soft-rigid combination board, and the like.

It may also be other types of image sensors other than CMOS or CCD, such as a charge injection device (CID) sensor.

[0166] It is understandable that for CMOS, a digital signal processor (DSP) can be integrated into CMOS. CMOS has the advantages of high integration, low power consumption, and low cost, and is more suitable for electronic devices with limited installation space, such as mobile phones.

[0167] In some possible implementations, the camera module may further include a flash. The flash may be a single-color temperature flash or a dual-color temperature flash. A dual-color temperature flash refers to a combination of a warm light flash and a cold light flash, which may be used for light compensation at different color temperatures.

[0168] Exemplarily, the camera module includes a front camera and a rear camera. Usually, the front camera is arranged on the front panel of the electronic device, and the rear camera is arranged on the back of the electronic device. In some embodiments, there are at least two rear cameras, which are any one of a main camera, a depth of field camera, a wide-angle camera, and a telephoto camera, so as to realize the fusion of the main camera and the depth of field camera to realize the background blur function, the fusion of the main camera and the wide-angle camera to realize the panoramic shooting and the virtual reality (VR) shooting function or other fusion shooting functions.

[0169] In the camera module provided in this embodiment, during the shooting process, the imaging light of the object enters the optical lens 20 and then reaches the image sensor. The photons in the imaging light hit the image sensor to generate movable charges. This is the internal photoelectric effect, and the movable charges gather to form an electrical signal.

[0170] The electrical signal is transmitted to the main board through a flexible circuit board or the like. The main board is provided with an analog-to-digital converter (A / D converter) and a digital signal processor (DSP). The A / D converter converts the electrical signal into a digital signal, which is processed by the DSP and finally transmitted to the screen of the electronic device to display the image, thus realizing the shooting of the object.

The imaging quality of the camera module is relatively high.
