[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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] A variable aperture is an aperture device that can be adjusted as needed to control the amount of light entering the camera (or 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 produce a shallow depth of field effect when shooting close subjects, making the subject stand out. A smaller aperture can limit the light entering the camera, making the photo darker. It can also produce a deep depth of field effect when shooting distant scenes, making the entire picture clear.

[0063] 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.

[0064] In related technologies, the variable aperture is limited by factors such as motion structure, driving method, and driving force, and cannot achieve volume optimization. It also has problems such as complex structure and high cost.

[0065] Therefore, the present application provides a variable aperture, in which the magnet and the induction coil are arranged in an inclined posture, which can generate the same electromagnetic driving force as in an upright posture without reducing the volume and / or size of the magnet and the induction coil, thereby facilitating the reduction of the size of the variable aperture and the miniaturization and micro-miniaturization of the camera module.

[0066] The electronic device provided by the present application can be any of various types of computer system devices that are mobile or portable and perform wireless communication. Specifically, the electronic device can be a mobile phone or smart phone (e.g., a phone based on iPhone TM, a phone based on Android TM), a portable game device (e.g., Nintendo DS TM, PlayStationPortable 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 can 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).

[0067] 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.

[0068] 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.

[0069] 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 with reference to the accompanying drawings.

[0070] On the one hand, combined with Figure 1 , Figure 2 and Figure 3 As shown, a variable aperture 100 is provided, and the variable aperture 100 includes a moving component 1, a stator component 2 and a driving component 3; the moving component 1 and the stator component 2 are coaxially arranged.

[0071] The coaxial arrangement of the mover assembly 1 and the stator assembly 2 exemplarily includes the mover assembly 1 being located radially inside the stator assembly 2 , and the mover assembly 1 being located radially outside the stator assembly 2 .

[0072] The driving component 3 includes at least one magnet 31 and at least one induction coil 32; at least one magnet 31 is arranged on one of the movable component 1 and the stator component 2, and at least one induction coil 32 is arranged on the other of the movable component 1 and the stator component 2; at least one magnet 31 and at least one induction coil 32 are arranged tilted respectively, and the tilting direction of at least one magnet 31 is the same as the tilting direction of at least one induction coil 32, so that at least one magnet 31 and at least one induction coil 32 remain parallel and relative to each other.

[0073] The variable aperture 100 of the present embodiment utilizes the electromagnetic effect generated between the magnet 31 and the induction coil 32 as a driving force to drive the rotor assembly to rotate relative to the stator assembly 2 to achieve aperture adjustment. The magnet 31 and the induction coil 32 are arranged in an inclined posture, so that compared with the upright posture arrangement, the size of the drive assembly 3 in a certain direction can be reduced, and the same electromagnetic driving force as the upright posture can be generated without reducing the volume and / or size of the magnet 31 and the induction coil 32, thereby facilitating the reduction of the size of the variable aperture 100 and facilitating the miniaturization and micro-miniaturization of the camera module.

[0074] In this embodiment, the number of the magnetic components 31 in the driving component 3 is, for example, one, two, three, etc.; the number of the induction coils 32 in the driving component 3 is, for example, one, two, three, etc. Exemplarily, the number of the magnetic components 31 and the induction coils 32 can be one-to-one corresponding, that is, each magnetic component 31 is parallel to one induction coil 32, or one-to-many, that is, each magnetic component 31 is parallel to multiple induction coils 32, or many-to-one, that is, multiple magnetic components 31 are parallel to one induction coil 32 at the same time.

[0075] When the number of the magnet pieces 31 is two or more, the magnet pieces 31 are arranged in sequence along the ring. When the number of the induction coils 32 is two or more, the induction coils 32 are arranged in sequence along the ring. In addition, during the relative rotation of the rotor assembly and the stator assembly 2, the magnet pieces 31 and the induction coils 32 remain parallel, and the spacing between them remains unchanged.

[0076] Among them, possible arrangements of the drive component 3 include arranging at least one magnet 31 on the movable component 1 and at least one induction coil 32 on the stator component 2; or arranging at least one induction coil 32 on the movable component 1 and at least one magnet 31 on the stator component 2.

[0077] In some possible implementations, the projection of the movable component 1 on the axis of the variable aperture 100 and the projection of the stator component 2 on the axis of the variable aperture 100 at least partially overlap, and the magnet 31 and the induction coil 32 are respectively arranged on the overlapping parts of the movable component 1 and the stator component 2, so that a magnetic interaction force field can be generated after the induction coil 32 is energized to generate a magnetic field.

[0078] In some possible implementations, the tilted arrangement of the magnet 31 and the induction coil 32 is intended to reduce the size of the variable aperture 100 in a certain direction, such as the axial size (also referred to as the height of the variable aperture 100). It may be tilted toward the position where the axis of the variable aperture 100 is located, or tilted away from the position where the axis of the variable aperture 100 is located; it may also be tilted along the circumferential rotation direction of the variable aperture 100. Any tilting method that can achieve the space occupation of the magnet 31 and the induction coil 32 in a specific direction without reducing the volume and / or effective working size of the magnet 31 and the induction coil 32 should be regarded as a variation of the present application.

[0079] In some possible implementations, the magnetic poles of the magnet 31 are arranged along the radial direction of the variable aperture 100, and the N pole may be toward the axis of the variable aperture 100 and the S pole may be away from the axis of the variable aperture 100; or the S pole may be toward the axis of the variable aperture 100 and the N pole may be away from the axis of the variable aperture 100.

[0080] In some other possible implementations, the axis of the induction coil 32 intersects with the axis of the variable aperture 100 , and the intersection positions of the axes of the plurality of induction coils 32 and the axis of the variable aperture 100 coincide.

[0081] When the number of the magnet pieces 31 is two or more, the magnetic poles of adjacent magnet pieces 31 are in opposite directions. When the number of the induction coils 32 is two or more, the directions of the currents of adjacent induction coils 32 are in opposite directions.

[0082] Combination Figure 3 As shown, in some embodiments, at least one magnet 31 includes a first end 3101 and a second end 3102 distributed along the axial direction of the variable aperture 100; the vertical distance from the first end 3101 to the axis of the variable aperture 100 is L1, and the vertical distance from the second end 3102 to the axis of the variable aperture 100 is L2, satisfying L1≠L2.

[0083] Through the above arrangement, the vertical distances between the first end 3101 and the second end 3102 of the magnet 31 and the axis of the variable aperture 100 are not equal, or it can be described as that one end of the magnet 31 is closer to the axis of the variable aperture 100 than the other end, thereby realizing the inclined arrangement of the magnet 31, thereby reducing the height dimension of the magnet 31 in the axial direction of the variable aperture 100.

[0084] Exemplarily, L1≠L2, it can be L1>L2, or L1<L2, both of which can achieve the inclined arrangement of the magnet 31.

[0085] Combination Figure 3As shown, in some embodiments, at least one induction coil 32 includes a third end 3201 and a fourth end 3202 distributed along the axial direction of the variable aperture 100; the vertical distance from the third end 3201 to the axis of the variable aperture 100 is L3, and the vertical distance from the fourth end 3202 to the axis of the variable aperture 100 is L4, satisfying L3≠L4.

[0086] Through the above arrangement, the vertical distances between the third end 3201 and the fourth end 3202 of the induction coil 32 and the axis of the variable aperture 100 are not equal, or described as one end of the induction coil 32 is closer to the axis of the variable aperture 100 than the other end, thereby realizing the inclined arrangement of the induction coil 32, thereby reducing the height dimension of the induction coil 32 in the axial direction of the variable aperture 100.

[0087] Exemplarily, L3≠L4, it can be L3>L4, or L3<L4, both of which can achieve the inclined arrangement of the induction coil 32.

[0088] Combination Figure 3 As shown, in some embodiments, the first end 3101 faces the light input side of the variable aperture 100, and the second end 3102 faces the light output side of the variable aperture 100, satisfying L1<L2; the third end 3201 faces the light input side of the variable aperture 100, and the fourth end 3202 faces the light output side of the variable aperture 100, satisfying L3<L4.

[0089] Therefore, the magnet 31 and the induction coil 32 in this embodiment are both inclined toward the axis of the variable aperture 100 at the end close to the light-incoming side. This inclination is more in line with the appearance of the variable aperture 100, and is more conducive to building a larger avoidance space on the light-outgoing side of the variable aperture 100, which can avoid the lens structure.

[0090] Combination Figure 3 As shown, in some embodiments, the movable component 1 is coaxially sleeved in the stator component 2, and the outer peripheral wall of the movable component 1 is arranged relative to the inner peripheral wall of the stator component 2; at least one magnet 31 is located on the outer peripheral wall of the movable component 1 or on the inner peripheral wall of the stator component 2, and at least one induction coil 32 is located on the outer peripheral wall of the movable component 1 or on the inner peripheral wall of the stator component 2.

[0091] Through the above arrangement, the magnet 31 and the induction coil 32 have a better facing posture, which can provide a more stable and reliable driving force for the rotor assembly.

[0092] In some possible implementations, reference Figure 8A roller assembly 6 is provided in the circumferential gap between the mover assembly 1 and the stator assembly 2. The roller assembly 6 can convert the friction between the stator assembly 2 and the mover assembly 1 into rolling friction, reduce the motion resistance between the stator assembly 2 and the mover assembly 1, and improve the relative rotation performance of the mover assembly 1 and the stator assembly 2. The axis of the roller assembly 6 is parallel to the axis of the variable aperture 100, so that rolling support uniformly distributed along the axial direction can be provided between the mover assembly 1 and the stator assembly 2, so that the relative rotation of the mover assembly 1 and the stator assembly 2 is more stable and reliable.

[0093] Combination Figure 4 As shown, in some embodiments, a recessed first receiving groove 111 is provided on the outer peripheral wall of the movable component 1, and at least one magnet 31 or at least one induction coil 32 is tiltedly arranged in the first receiving groove 111; a recessed second receiving groove 211 is provided on the inner peripheral wall of the stator component 2, and at least one magnet 31 or at least one induction coil 32 is tiltedly arranged in the second receiving groove 211.

[0094] Through the above arrangement, the magnet 31 and the induction coil 32 are respectively arranged in the first accommodating groove 111 and the second accommodating groove 211 , which reduces the radial dimension occupied by the magnet 31 and the induction coil 32 of the variable aperture 100 , thereby facilitating the reduction of the volume of the variable aperture 100 .

[0095] In some possible implementations, there are multiple ways to tilt the magnet 31 in the first receiving slot 111, for example, the first receiving slot 111 itself is a tilted slot, or a support structure capable of raising one end of the magnet 31 is provided in the first receiving slot 111. There are also multiple ways to tilt the induction coil 32 in the second receiving slot 211, for example, the second receiving slot 211 itself is a tilted slot, or a support structure capable of raising one end of the induction coil 32 is provided in the first receiving slot 111.

[0096] Combination Figure 4 As shown, in some embodiments, the first receiving slot 111 is arranged obliquely, and the inclination direction of the first receiving slot 111 is the same as the inclination direction of at least one magnet 31 or at least one induction coil 32; the second receiving slot 211 is arranged obliquely, and the inclination direction of the first receiving slot 111 is the same as the inclination direction of at least one magnet 31 or at least one induction coil 32. The magnet 31 or the induction coil 32 placed therein can be tilted by the first receiving slot 111 or the second receiving slot 211 which are arranged obliquely.

[0097] Combination Figure 3 and Figure 4 As shown, in some embodiments, at least one magnet 31 is obliquely disposed on the outer circumferential wall of the mover assembly 1 , and at least one induction coil 32 is obliquely disposed on the inner circumferential wall of the stator assembly 2 .

[0098] Through the above arrangement, the mover assembly 1 and the magnet 31 are located inside the mover assembly 1 and the induction coil 32 , and the induction coil 32 can be conveniently designed and connected to the circuit from the outside.

[0099] Combination Figure 5 and Figure 6 As shown, in some embodiments, the variable aperture 100 further includes a circuit component 4 , which is located on the outer peripheral wall of the stator component 2 , and is electrically connected to at least one induction coil 32 .

[0100] The circuit assembly 4 arranged on the outer peripheral wall of the stator assembly 2 can be conveniently electrically connected to the induction coil 32 in the second receiving groove 211 to provide an electrical signal for the induction coil 32 .

[0101] In some possible implementations, the circuit assembly 4 includes a circuit board body, which may be a printed circuit board (PCB), a flexible printed circuit board (FPC), a rigid-flexible board, or the like.

[0102] Optionally, the circuit board body is a flexible printed circuit board, so that it can be designed in a conformal manner with the outer peripheral wall of the stator assembly 2, making full use of the outer peripheral wall space of the stator assembly 2 and reducing the space occupied by the circuit assembly 4. The circuit board body includes at least one terminal 421, and the terminal 421 is connected to an external circuit, such as the upper spring structure in the focus drive module.

[0103] Combination Figure 5 and Figure 6 As shown, in some embodiments, the second accommodating groove 211 penetrates the stator assembly 2 along the radial direction to the outer peripheral wall of the stator assembly 2, at least part of the circuit assembly 4 extends to the second accommodating groove 211, and a support member 41 is provided on the surface of the circuit assembly 4 facing at least one induction coil 32, and the support member 41 is used to raise one end of at least one induction coil 32.

[0104] Through the above arrangement, the support member 41 raises one end of the induction coil 32 to achieve an inclined arrangement of the induction coil 32 , and can facilitate the electrical connection between the circuit component 4 and the induction coil 32 , with a simple and efficient structure.

[0105] Combination Figure 7 and Figure 8As shown, in some possible implementations, the variable aperture 100 further includes a pre-tightening component 5, which is used to form a pre-tightening force between the stator component 2 and the movable component 1, so that the stator component 2 and the movable component 1 are stably and reliably tightly matched. Optionally, the pre-tightening component 5 is a pair of magnetic parts, which are arranged on the stator component 2 and the movable component 1, respectively, to generate a continuous magnetic attraction or magnetic repulsion, so that the stator component 2 and the movable component 1 are tightly matched. Another option is that one of the magnetic parts of the pre-tightening component 5 is located outside the induction coil 32, and the magnetic part can attract or repel each other with the magnet part 31 in the driving component 3, so that the stator component 2 and the movable component 1 are tightly matched.

[0106] Combination Figure 7 and Figure 8 As shown, in some possible implementations, the variable aperture 100 further includes a cover plate 7 and a blade assembly 8. The cover plate 7 and the blade assembly 8 are both located on the light-incoming side of the variable aperture 100. The blade assembly is composed of a plurality of movable blades, each of which is movably connected to the stator assembly 2 and the movable assembly 1 at the same time. When the movable assembly 1 rotates relative to the stator assembly 2, each movable blade is driven to move along a specific trajectory, changing its own extended size. When a plurality of movable blades move at the same time, it is reflected as the enlargement or reduction of the aperture.

[0107] Optionally, the mover assembly 1 includes a mover body 11, and the stator assembly 2 includes a stator body 21. The mover body 11 is provided with a plurality of first connection parts 112 at one end facing the light input side, and the stator body 21 is provided with a plurality of second connection parts 212 at one end facing the light input side. Each movable blade is movably connected to a first connection part 112 and a second connection part 212 respectively.
