Description

Technical Field

[0001] This application belongs to the field of camera technology, specifically relating to an aperture component, a camera, and an electronic device. Background Technology

[0002] Variable aperture technology allows users to take better photos under different lighting conditions. The aperture size can be adjusted within a certain range using a set of rotating or movable blades.

[0003] In related technologies, such as Figure 1 As shown, the blades are usually mounted on the carrier 12'. The carrier 12' rotates by the rolling friction between the ball bearing 17' and the housing 11', thereby driving the blades to move and realize the opening and closing of the blades. Therefore, the material cost requires the addition of ball bearings, and the process assembly requires the arrangement of ball bearing assembly stations and inspection equipment or manual labor to check whether ball bearings are missing, which greatly increases the assembly difficulty and cost of the variable aperture assembly. Utility Model Content

[0004] The purpose of this application is to provide an aperture assembly, camera, and electronic device that can solve the technical problems of high assembly difficulty and high cost of aperture assemblies.

[0005] In a first aspect, embodiments of this application provide an aperture assembly, including:

[0006] The housing includes a plurality of first positioning parts;

[0007] The carrier is disposed inside the housing. The carrier includes a first main body and a plurality of second positioning parts. The second positioning parts are disposed on the first main body. The peripheral sidewall of the first main body includes a plurality of protrusions facing the housing and abutting against the housing.

[0008] A drive assembly, comprising a drive unit and a movable unit, wherein the drive unit is disposed in the housing and the movable unit is disposed in the carrier;

[0009] Multiple blades are disposed inside the housing. Each blade includes a third positioning part and a fourth positioning part. The third positioning part cooperates with the first positioning part, and the fourth positioning part cooperates with the second positioning part. The blades, the first positioning part, and the second positioning part correspond one-to-one.

[0015] The second aspect embodiment provides a camera, a second circuit board, and a driver unit for the camera's aperture assembly that are electrically connected.

[0016] In this embodiment, the aperture assembly includes a housing, a carrier, a drive assembly, and multiple blades. The carrier is disposed inside the housing. The drive assembly includes a drive part and a movable part. The drive part is disposed in the housing, and the movable part is disposed in the carrier. Each of the multiple blades is connected to the carrier and the housing. When the drive part drives the movable part to rotate, the movable part drives the blades to rotate, thereby changing the size of the aperture surrounding the multiple blades and realizing the adjustment of the aperture size.

[0017] The housing includes multiple first positioning parts, the carrier includes a first main body and multiple second tops disposed on the first main body, each blade includes a third positioning part and a fourth positioning part, the third positioning part of each blade cooperates with a first positioning part, and the fourth positioning part of each blade cooperates with a second positioning part, so that when the carrier and the housing rotate relative to each other, the blades will also rotate. The cooperation of multiple blades can adjust the size of the aperture.

[0018] The peripheral sidewall of the first main body includes multiple protrusions, which face the housing and abut against it. In other words, the carrier is supported in the housing by the protrusions. Since the protrusions are part of the first main body, there is no need to assemble the protrusions separately when assembling the carrier and the housing, thereby reducing the installation difficulty of the carrier and the housing, reducing production costs, and improving the yield of the aperture assembly.

[0037] The following is combined with Figures 2 to 9 This application describes an aperture assembly 1, a camera 2, and an electronic device 3 according to embodiments thereof.

[0038] Firstly, such as Figure 2 , Figure 3 and Figure 4 As shown, this application embodiment provides an aperture assembly 1, including: a housing 11, the housing 11 including a plurality of first positioning parts 111; a carrier 12, disposed within the housing 11, the carrier 12 including a first main body 121 and a plurality of second positioning parts 125, the second positioning parts 125 being disposed on the first main body 121, the peripheral sidewall 122 of the first main body 121 including a plurality of protrusions 123 facing the housing 11, the protrusions 123 abutting against the housing 11; a drive assembly 13, the drive assembly 13 including a drive part 131 and a movable part 132, the drive part 131 being disposed on the housing 11, the movable part 132 being disposed on the carrier 12; and a plurality of blades 14, disposed within the housing 11, the blades 14 including a third positioning part 141 and a fourth positioning part 142, the third positioning part 141 cooperating with the first positioning part 111, the fourth positioning part 142 cooperating with the second positioning part 125, the blades 14, the first positioning parts 111 and the second positioning parts 125 corresponding one-to-one.

[0039] In this embodiment, the aperture assembly 1 includes a housing 11, a carrier 12, a drive assembly 13, and multiple blades 14. The carrier 12 is disposed inside the housing 11. The drive assembly 13 includes a drive part 131 and a movable part 132. The drive part 131 is disposed in the housing 11, and the movable part 132 is disposed in the carrier 12. Each of the multiple blades 14 is connected to the carrier 12 and the housing 11. When the drive part 131 drives the movable part 132 to rotate, the movable part 132 drives the blades 14 to rotate, thereby changing the size of the aperture surrounding the multiple blades 14 and realizing the adjustment of the aperture size.

[0040] The housing 11 includes a plurality of first positioning parts 111, the carrier 12 includes a first main body 121 and a plurality of second positioning parts 125 disposed on the first main body 121, and each blade 14 includes a third positioning part 141 and a fourth positioning part 142. The third positioning part 141 of each blade 14 cooperates with a first positioning part 111, and the fourth positioning part 142 of each blade 14 cooperates with a second positioning part 125. Thus, when the carrier 12 and the housing 11 rotate relative to each other, the blade 14 will also rotate. The cooperation of multiple blades 14 can adjust the size of the aperture.

[0041] The peripheral sidewall 122 of the first main body 121 includes multiple protrusions 123, which face the housing 11 and are in contact with the housing 11. In other words, the carrier 12 is supported in the housing 11 by the protrusions 123. When the carrier 12 rotates relative to the housing 11, only the protrusions 123 and the housing 11 rub against each other, thereby reducing the friction between the carrier 12 and the housing 11. Since the protrusions 123 are part of the first main body 121, there is no need to assemble the protrusions 123 separately when assembling the carrier 12 and the housing 11, thereby reducing the installation difficulty of the carrier 12 and the housing 11, reducing production costs, and improving the yield of the aperture assembly 1.

[0042] The number of protrusions 123 can be greater than or equal to three, thereby improving the stability of the rotation of the carrier 12. For example, the number of protrusions 123 can be three, four, five, six or ten, etc.

[0043] That is, multiple protrusions 123 are provided to protrude outward from the periphery of the carrier 12. The carrier 12 is driven to rotate by the power supply of the drive assembly 13. The protrusions 123 of the carrier 12 rub against the inner side of the housing 11, overcoming the frictional force and driving the blades 14 to rotate to achieve aperture change.

[0044] The surface of the protrusion 123 may be coated with lubricating oil to reduce the friction between the protrusion 123 and the housing 11 and improve the performance of the aperture assembly 1.

[0045] For example, four protrusions 123 are provided on the periphery of the carrier 12. The protrusions 123 and the first main body 121 are integral structures. After the driving component 13 is powered on, the carrier 12 rotates, causing the four protrusions 123 on the periphery of the carrier 12 to slide against the inner side of the cover 113, thereby causing the blade 14 to rotate to achieve the change of the aperture.

[0046] like Figure 5 As shown, in one possible implementation, the first body 121 and the protrusion 123 are an integral structure; the first body 121 and the protrusion 123 are made of metal.

[0047] Specifically, the first body 121 and the protrusion 123 are an integral structure. The first body 121 and the protrusion 123 are made of metal. Metal has good wear resistance, which improves the service life of the protrusion 123. Furthermore, the integral structure of the first body 121 and the protrusion 123 can be integrally injection molded or stamped, which reduces the processing difficulty and helps to reduce production costs.

[0048] For example, the peripheral sidewall 122 of the first body 121 is provided with a protrusion 123 made of plastic. The first body 121 and the protrusion 123 are both made of metal. The carrier 12 is integrally molded, so that the protrusion 123 of the peripheral sidewall 122 of the first body 121 replaces the conventional ball or guide rod structure. The metal carrier 12 has higher hardness and higher reliability, which can improve the reliability of the aperture assembly 1 and reduce the risk of impact deformation and dents after drop.

[0049] For example, the first body 121 and the protrusion 123 may be made of aluminum, aluminum alloy, copper, copper alloy, zinc or zinc alloy, etc.

[0050] like Figure 6 As shown, in one possible implementation, the first body 121 and the protrusion 123 are an integral structure; the first body 121 and the protrusion 123 are made of plastic.

[0051] Specifically, the first body 121 and the protrusion 123 are an integral structure. The first body 121 and the protrusion 123 are made of plastic. Plastic is lightweight and low-cost. Furthermore, the integral structure of the first body 121 and the protrusion 123 can be injection molded in one piece, which is easy to process and helps to reduce production costs.

[0052] For example, the peripheral sidewall 122 of the first body 121 is provided with a protrusion 123 made of plastic. The first body 121 and the protrusion 123 are both made of plastic. The carrier 12 is integrally molded so that the protrusion 123 of the peripheral sidewall 122 of the first body 121 replaces the conventional ball or guide rod structure, saving the cost of the aperture assembly 1 without affecting the performance of the aperture assembly 1.

[0053] For example, the first body 121 and the protrusion 123 may be polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyethylene terephthalate, acrylonitrile-butadiene-styrene copolymer, polyamide, polycarbonate, polyoxymethylene, polybutylene terephthalate or polytetrafluoroethylene, etc.

[0054] like Figure 7 As shown, in one possible implementation, the protrusion 123 is made of metal, the first body 121 is made of plastic, and the protrusion 123 is fixed to the first body 121.

[0055] Specifically, the protrusion 123 is made of metal, and the first body 121 is made of plastic. The plastic first body 121 is lightweight and low in cost, while the metal protrusion 123 has high wear resistance, which improves the service life of the protrusion 123. Furthermore, the protrusion 123 can be fixed to the first body 121 by means of insert injection molding, screwing, or plugging, thereby achieving the connection and fixation between the protrusion 123 and the first body 121.

[0056] For example, the peripheral sidewall 122 of the first body 121 is provided with a protrusion 123. The first body 121 is made of plastic and the protrusion 123 is made of metal. The protrusion 123 of the peripheral sidewall 122 of the first body 121 replaces the conventional ball or guide rod structure, saving the cost of the aperture assembly 1 without affecting the performance of the aperture assembly 1.

[0057] The metal protrusion 123 has higher hardness and reliability, which can improve the reliability of the aperture assembly 1 and reduce the risk of deformation and dents after a drop.

[0058] For example, the first body 121 may be made of aluminum, aluminum alloy, copper, copper alloy, zinc, or zinc alloy, etc. The protrusion 123 may be made of polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyethylene terephthalate, acrylonitrile-butadiene-styrene copolymer, polyamide, polycarbonate, polyoxymethylene, polybutylene terephthalate, or polytetrafluoroethylene, etc.

[0059] like Figure 2 As shown, in one possible implementation, the second positioning part 125 is columnar, and the fourth positioning part 142 is groove-shaped or hole-shaped, with the second positioning part 125 passing through the fourth positioning part 142; the aperture assembly 1 also includes: a gasket 15, disposed between the carrier 12 and the plurality of blades 14, the gasket 15 including a plurality of fifth positioning parts 151, the fifth positioning parts 151 being hole-shaped, with the second positioning part 125 passing through the fifth positioning parts 151.

[0060] Specifically, the second positioning part 125 is columnar, and the fourth positioning part 142 is groove-shaped or hole-shaped. The second positioning part 125 can be inserted into the fourth positioning part 142, so that the second positioning part 125 and the fourth positioning part 142 constrain each other. When the second positioning part 125 rotates with the carrier 12, the fourth positioning part 142 is driven to move by the second positioning part 125, thereby causing the blade 14 to rotate.

[0061] The aperture assembly 1 also includes a spacer 15 disposed between the carrier 12 and the plurality of blades 14. The spacer 15 includes a plurality of fifth positioning portions 151, which are perforated. The second positioning portion 125 passes through the fifth positioning portion 151, thereby reducing the wear between the blades 14 and the carrier 12 and improving the service life of the aperture assembly 1.

[0062] That is, the second positioning part 125 is a columnar fourth positioning part 142 sleeved on the outside of the second positioning part 125.

[0063] like Figure 2 As shown, in one possible implementation, the first positioning part 111 is columnar, and the third positioning part 141 is groove-shaped or hole-shaped, with the first positioning part 111 passing through the third positioning part 141. Alternatively, the first positioning part 111 is groove-shaped or hole-shaped, and the third positioning part 141 is columnar, with the third positioning part 141 passing through the first positioning part 111.

[0064] like Figure 2 and Figure 3 As shown, in one possible implementation, the housing 11 includes: a base 112 located on one side of the carrier 12; a cover 113 fixedly connected to the base 112, the cover 113 surrounding the carrier 12, a protrusion 123 contacting the cover 113, and a first positioning part 111 located on the side of the cover 113 away from the base 112; a first circuit board 115 disposed on the outside of the cover 113, and a driving part 131 disposed on the first circuit board 115; a cover plate 116 covering the end of the cover 113 away from the base 112, and the cover plate 116 covering the first positioning part 111; wherein, a second positioning part 125 is located on the side of the carrier 12 away from the base 112.

[0065] Specifically, the housing 11 includes a base 112, a cover 113, a first circuit board 115, and a cover plate 116. The base 112 is located on one side of the carrier 12, and the cover 113 and the carrier 12 are located on the same side of the base 112. The cover 113 is arranged around the carrier 12, such that the carrier 12 is located inside the cover 113. The cover plate 116 is arranged on the side of the cover 113 away from the base 112. Thus, the base 112, the cover 113, and the cover plate 116 protect the carrier 12 and the blade 14 inside. The first circuit board 115 is arranged on the outside of the cover plate 116, and the drive unit 131 is arranged on the first circuit board 115, thereby facilitating the power supply of the drive unit 131.

[0066] The first positioning part 111 is located on the side of the cover 113 away from the base 112, and the second positioning part 125 of the carrier 12 is located on the side of the carrier 12 away from the base 112, so as to facilitate the cooperation of the first positioning part 111 and the second positioning part 125. Furthermore, the cover plate 116 covers the first positioning part 111, thereby reducing the possibility of the blade 14 detaching from the first positioning part 111. The above structure facilitates the disassembly and assembly of the housing 11, and facilitates the installation and maintenance of the aperture assembly 1, etc.

[0067] For example, a mounting groove is provided on the outer side of the cover 113, and the first circuit board 115 is embedded in the mounting groove, thereby reducing the volume of the aperture assembly 1.

[0068] That is, along the radial direction CD of the aperture assembly 1, the cover 113 is located outside the carrier 12, and along the axial direction AB of the aperture assembly 1, one side of the carrier 12 is the base 112, and the other side is the cover plate 116.

[0069] like Figure 2 and Figure 3 As shown, in one possible implementation, a first boss 124 is provided in the middle region of the side of the first body 121 away from the base 112, and a second positioning part 125 is provided on the first boss 124; an edge 114 is provided on the side of the cover 113 away from the base 112, the edge 114 is provided around the first boss 124, and at least a portion of the edge 114 extends toward the first boss 124.

[0070] Specifically, a first protrusion 124 is provided in the middle area of ​​the side of the first main body 121 away from the base 112, and a second positioning part 125 is provided on the first protrusion 124, which facilitates the leveling of the second positioning part 125 and the first positioning part 111, making the movement of the blade 14 more stable. An edge 114 is provided on the side of the cover 113 away from the base 112. The edge 114 surrounds the first protrusion 124, and at least a portion of the edge 114 extends toward the first protrusion 124. The first positioning part 111 is located outside the second positioning part 125, so that the edge 114 can limit the carrier 12, reduce the possibility of the carrier 12 moving along the axial direction AB, and improve the reliability of the aperture assembly 1.

[0071] Along the axial direction AB of the aperture assembly 1, the edge 114 is opposite to the first body 121.

[0072] like Figure 2 and Figure 3 As shown, in one possible implementation, the driving part 131 is a coil, the moving part 132 is a magnetic component, and the aperture assembly 1 further includes a magnetic sensor 16, which is disposed on the first circuit board 115. The magnetic sensor 16 and the moving part 132 are disposed opposite to each other, and the magnetic sensor 16 is used to detect changes in the magnetic field of the moving part 132.

[0073] Specifically, the driving part 131 is a coil, and the moving part 132 is a magnetic component. When the coil is energized, it interacts with the magnetic field of the magnetic component, thereby driving the magnetic component to move relative to the coil, thus realizing the movement of the carrier 12 relative to the shell 11.

[0074] The aperture assembly 1 also includes a magnetic sensor 16 disposed on the first circuit board 115. The magnetic sensor 16 and the movable part 132 are disposed opposite to each other. The magnetic sensor 16 is used to detect the change in the magnetic field of the movable part 132. The rotation angle of the carrier 12 can be determined by the change in the magnetic field of the movable part 132. The rotation angle of the carrier 12 can reflect the rotation angle of the blade 14, thereby realizing the detection of the aperture size and facilitating the intelligent adjustment of the aperture size of the aperture assembly 1.

[0075] For example, the magnetic sensor 16 may be a reed switch or a Hall sensor, etc.

[0076] The magnetic sensor 16 can be integrated into an integrated circuit (IC).

[0077] like Figure 2 and Figure 3 As shown, in one possible implementation, the housing 11 and the carrier 12 are annular. The base 112, the cover 113, and the cover plate 116 are all annular.

[0078] like Figure 2 and Figure 3 As shown, in one possible implementation, the base 112 includes a second boss 117 on the side facing the carrier 12, the carrier 12 and the second boss 117 are disposed opposite to each other, and the cover 113 surrounds the outside of the second boss 117.

[0079] like Figure 2 and Figure 3As shown, in one possible implementation, the aperture assembly 1 provided in this application integrates the features of a ball bearing with the carrier 12. Multiple protrusions 123 are provided on the periphery of the carrier 12. The number of protrusions 123 can be three, four, five, or six, etc. The protrusions 123 replace the ball bearings in the related technology. The carrier 12 rotates through the friction between the protrusions 123 and the inner side of the housing 11, thereby reducing the number of ball bearing components. This can also reduce the difficulty of the manufacturing process of the aperture assembly 1, greatly improve the production efficiency of the aperture assembly 1, and save the cost of the aperture assembly 1.

[0080] For example, the aperture assembly 1 provided in the embodiments of this application includes a housing 11, a carrier 12, a drive assembly 13, a blade 14, a pad 15 and a magnetic sensor 16, wherein the drive assembly 13 includes a drive part 131 and a moving part 132, and the housing 11 includes a base 112, a cover 113, a cover plate 116 and a first circuit board 115.

[0081] The base 112 is used to support the carrier 12 and also protect the internal components of the aperture assembly 1.

[0082] The movable part 132 can be a magnetic component. The movable part 132 is connected to the carrier 12. When the driving part 131 is energized, it generates electromagnetic force to provide power for the movement of the carrier 12.

[0083] The carrier 12 is used to assemble the movable part 132, support the blade 14, and drive the blade 14 to rotate.

[0084] The magnetic sensor 16 includes a Hall sensor, which provides positioning for precise focusing of the camera.

[0085] The driving part 131 can be a coil. When the driving part 131 is energized, it interacts with the moving part 132 to generate electromagnetic force.

[0086] The first circuit board 115 has lead wire pins to connect to external circuits.

[0087] The gasket 15 supports the blade 14 and reduces the friction between the blade 14 and the carrier 12.

[0088] The aperture changes by rotating the blade 14.

[0089] The cover 113 supports the blade 14 and also protects the internal components of the aperture assembly 1.

[0090] The cover plate 116 covers the outer ring of the blade 14 and is located on the side of the cover body 113 away from the base 112.

[0091] In this assembly, the carrier 12, the movable part 132, and the gasket 15 constitute the rotating part of the aperture assembly 1. The base 112 serves as the load-bearing part. The cover plate 116 shields the outer ring of the blade 14 on the side opposite to the carrier 12. The cover plate 116 is fixedly connected to the cover body 113 or the base 112 by hot riveting and applying adhesive. The magnetic sensor 16 and the drive unit 131 are on the first circuit board 115. Four power-conducting pads are arranged on both sides of the first circuit board 115. After forming the assembly, they are fixed around the cover body 113. The drive unit 131 and... The magnetic sensor 16 faces the drive unit 131. The third positioning part 141 at the root of the blade 14 is sleeved on the first positioning part 111 of the cover 113.
