A periscopic module integrated with a variable aperture, a camera module and an electronic device

Abstract

This invention discloses a periscope module, camera module, and electronic device integrating a variable aperture. The variable aperture assembly is arranged to connect to the lens zoom assembly along the optical axis. The variable aperture assembly is configured as a variable aperture housing and includes a first drive assembly, a second drive assembly, a first blade group, and a second blade group arranged within the housing. The first and second blade groups are arranged on opposite sides of the optical axis radially, with the first and second drive assemblies correspondingly arranged. Both drive assemblies are configured to output radial drive motion and transmit it to the blades of the corresponding blade group, thereby creating light-transmitting apertures of different diameters. By changing the drive method from conventional rotating components to radial drive, the thickness of the drive assembly in the optical axis direction can be effectively reduced, thus lowering the thickness of the variable aperture assembly in the optical axis direction. This results in minimal change in the overall length formed by the variable aperture assembly and the lens zoom assembly, leading to a miniaturized device.

Description

Technical Field

[0001] This invention belongs to the field of camera technology, and particularly relates to a periscope module with integrated variable aperture, a camera module, and an electronic device. Background Technology

[0002] The aperture size of a mobile phone camera is an important factor affecting the photo quality. A large aperture camera allows more light to enter the camera module, shortening the shutter speed and making it suitable for shooting moving objects. It also has a shallow depth of field, which can be used to blur the background and highlight the subject. On the other hand, a small aperture camera has a longer shutter speed, making it suitable for shooting car trails and star trails. It also has a deeper depth of field, ensuring that objects within a wide depth range are sharp.

[0003] Compared to the zoom capabilities of traditional cameras, periscope cameras offer superior optical zoom, achieving up to 10x optical zoom, which has led to their gradual adoption in the mobile phone industry. However, current technology makes it difficult to adjust the aperture size of periscope cameras in multiple increments to alter the intensity of incident light and depth of field, thus affecting image quality and limiting their applicability.

[0004] Publication No. CN113867074A presents a technical solution for setting a variable aperture in a periscope lens. This variable aperture is achieved by a motor-driven lead screw, which in turn drives a nut slider and light-blocking blades on the slider in a linear motion to change the aperture. The problems are limited adjustment range and effect, and the motor-driven design occupies a large space, hindering the miniaturization of the periscope module. Publication No. CN110677565A presents a technical solution that sets the variable aperture on the prism assembly. However, setting the variable aperture on the light-incident surface of the prism assembly affects the overall height / thickness of the periscope module, thus hindering the thinning of the camera module. Furthermore, when the prism assembly has image stabilization capabilities, setting and adjusting the variable aperture on the prism assembly becomes significantly more difficult.

[0046] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed account of the periscope module, camera module, and electronic device with integrated variable aperture proposed in this invention. The advantages and features of this invention will become clearer from the following description and claims.

[0047] Example 1

[0048] See Figures 1 to 8 In one embodiment, a periscope module with an integrated variable aperture includes a lens zoom assembly 2 and a variable aperture assembly 1.

[0049] The variable aperture assembly 1 is mounted on the lens zoom assembly 2 along the optical axis. The variable aperture assembly 1 includes a variable aperture housing and a first drive assembly, a second drive assembly, a first blade group, and a second blade group arranged within the variable aperture housing.

[0050] The first and second blade groups are respectively arranged on both sides of the optical axis radially. The blades 103 in the first blade group and the blades 103 in the second blade group together form a light-transmitting aperture. The first driving assembly and the second driving assembly are respectively arranged on both sides of the optical axis radially. The first driving assembly corresponds to the first blade group, and the second driving assembly corresponds to the second blade group. The first driving assembly and the second driving assembly are respectively configured to output the blades 103 of the first blade group and the blades 103 of the second blade group to move radially. The blades 103 are configured to rotate relative to the variable aperture housing under radial drive, and the aperture of the light-transmitting aperture formed by the multiple blades 103 changes.

[0051] In this embodiment, the variable aperture assembly 1 is arranged to connect with the lens zoom assembly 2 along the optical axis. The variable aperture assembly 1 is configured as a variable aperture housing and includes a first drive assembly, a second drive assembly, a first blade group, and a second blade group arranged within the housing. The first and second blade groups are arranged on opposite sides of the optical axis radially, and the first and second drive assemblies are respectively arranged corresponding to the first and second blade groups. Both the first and second drive assemblies are configured to output radial drive motion and transmit it to the blades 103 of the corresponding blade groups. The blades 103 are configured to rotate relative to the variable aperture housing under radial drive, thereby forming light-transmitting holes of different diameters. By changing the driving method of the blades 103 from conventional rotating component drive to radial drive, the thickness of the drive assembly in the optical axis direction can be effectively reduced, thereby reducing the thickness of the variable aperture assembly 1 in the optical axis direction. This results in minimal change in the overall length formed by the variable aperture assembly 1 and the lens zoom assembly 2, minimizing the overall thickness (height) of the device and solving the problem of integrating a variable aperture in existing periscope modules due to size constraints.

[0052] Furthermore, in this embodiment, the blade assembly and the drive assembly are respectively arranged on opposite sides of the optical axis radial direction, so that the variable aperture assembly 1 only has an extension in size in this radial direction. The thickness of the variable aperture assembly 1 in the optical axis direction and the width dimension perpendicular to the optical axis and the radial direction can be controlled to be very small, thereby realizing the miniaturization of the entire device.

[0053] The specific structure of the periscope module with integrated variable aperture in this embodiment will be further described below:

[0054] In this embodiment, both the first driving component and the second driving component described above may include a slider 106 and a driving component.

[0055] The slider 106 can be specifically arranged to slide radially connected to the variable aperture housing, and the output end of the slider 106 is configured to slide with the corresponding blade 103 respectively (that is, the number of output ends on the slider 106 matches the number of blades 103 in the corresponding blade group); the driving member is arranged in the variable aperture housing and configured to drive the corresponding slider 106 to slide radially. In other embodiments, the second driving component may not be an independent driving structure, but may be configured as a transmission structure connected to the first driving component, and thus output radial movement on the other side under the drive of the first driving component, without specific limitation here.

[0056] Specifically, the driving component may include a driving coil 108 and a driving magnetic component 107. The driving coil 108 is mounted on the variable aperture housing, and the driving magnetic component 107 is mounted on the slider 106. The driving magnetic component 107 is used to drive the slider 106 to slide radially inward or outward (towards or away from the optical axis) when the driving coil 108 is energized.

[0057] Furthermore, the driving magnetic component 107 can specifically be a driving magnet, including a monopole magnet, a multi-level magnet, or a Heilbeck array magnet. The installation method can be to open a mounting groove on the slider 106 and embed the driving magnet into the mounting groove, or it can be configured to be integrally formed with the slider 106.

[0058] In this embodiment, the variable aperture housing may specifically include a mounting cover and a connecting housing 109. The mounting cover fits onto the connecting housing 109 to form a chamber for mounting the aforementioned drive assembly and blade assembly. The connecting housing 109 has a blade support platform that at least partially surrounds the optical axis and two side chambers located radially on either side of the blade support platform on its surface facing the mounting cover. The aforementioned sliding member 106 is radially slidably connected to the side chambers, and the drive coil 108 is mounted in either the side chamber or on the mounting cover.

[0059] Specifically, the shape of the mounting cover can be set as a cuboid, including a rectangular plate-shaped cover body and four rectangular walls surrounding the plate-shaped cover body; similarly, the connecting housing 109 is also a cuboid, and the mounting cover is placed on the connecting housing 109 to form a cuboid variable aperture assembly 1. The cuboid variable aperture assembly 1 can specifically include two short side sides and two long side sides parallel to the optical axis direction, and the short side sides are perpendicular to the aforementioned radial direction.

[0060] In this embodiment, in order to achieve a sliding connection, two radial guide structures can be provided at intervals on the bottom surface of the side chamber, and two corresponding guide mating structures are provided on the bottom surface of the slider 106.

[0061] The radial guiding structure is a guide post 110 arranged on the bottom surface of the side chamber (which can be achieved by opening two elongated grooves on the bottom surface of the side chamber, placing the guide post 110 in the grooves and having at least part of the guide post 110 protruding from the bottom surface of the side chamber, thus playing a guiding role; or the guide post 110 can be directly integrally formed with the connecting housing 109), or the radial guiding structure is a plurality of rollers or balls arranged radially on the bottom surface of the side chamber (the arrangement is also that two elongated grooves are opened on the bottom surface of the side chamber, the rollers or balls are arranged in the grooves and have at least part of protruding from the bottom surface of the side chamber).

[0062] See Figure 6The two guiding and mating structures mentioned above can be a positioning guide groove 1063 and a mating allowance guide groove 1064 respectively formed on the bottom surface of the sliding member 106. Specifically, the positioning guide groove 1063 can be a V-shaped groove, which limits the relative position of the corresponding guide post 110 or roller after mating; while the mating allowance guide groove 1064 can be a flat groove or a U-shaped groove, forming a partial mating allowance. If both are V-shaped grooves, due to the difference in machining accuracy, the two sliding shafts may get stuck or be difficult to assemble during assembly.

[0063] See Figure 3 In this embodiment, since the driving magnetic component 107 is mounted on the sliding component 106, and the bottom surface of the side chamber needs to be used as a mating surface for sliding connection, the aforementioned driving coil 108 can be mounted on the mounting cover and arranged facing the sliding component 106. Specifically, the positioning method is to position and install it on the mounting cover by the coil positioning post 1021. In order to avoid the sliding component 106 hitting the driving coil 108 upward when it receives an external force impact, in this embodiment, the bottom end of the coil positioning post 1021 is set to extend out of the surface of the driving coil 108 facing the sliding component 106. That is, when the sliding component 106 hits upward, it hits the bottom end surface of the coil positioning post 1021, preventing the sliding component 106 and the driving magnetic component 107 on it from directly hitting the driving coil 108.

[0064] In this embodiment, the mounting end cap may specifically include a metal outer shell 101 and a plastic upper cover 102 (wherein, the plate-shaped cover body may be formed by matching the metal outer shell 101 and the plastic upper cover 102, and the four rectangular walls surrounding the plate-shaped cover body may be extension walls of the metal outer shell 101 extending at the edge of the cover body), the two are fixedly connected to form a closed cover, and a light-transmitting hole is provided in the center.

[0065] See Figure 5 In this embodiment, to avoid damage or deformation to the plastic structure caused by the large impact force of the sliding member 106 hitting the plastic cover 102 under external force, at least one protective boss 1061 can be provided on the surface of the sliding member 106 facing the mounting cover. The protective boss 1061 extends towards the mounting end cover along the optical axis (specifically, it can be two protective bosses 1061 located on both sides of the driving magnetic member 107), and the protective boss 1061 is arranged to avoid the driving coil 108 in the optical axis direction to avoid hitting the driving coil 108. The plastic cover 102 can be provided with a corresponding avoidance groove for the protective boss 1061, so that when the sliding member 106 hits upward, the protective boss 1061 hits the metal shell 101.

[0066] In this embodiment, in order to ensure the sliding stability of the slider 106, the periscope module with integrated variable aperture may also include a bottom magnetic plate 111 disposed on the connecting housing 109 (specifically, it may be disposed on the bottom surface of the connecting housing 109, that is, the surface of the connecting housing 109 facing the lens zoom assembly 2; specifically, it may be installed by opening a recessed groove, attaching or embedding, and generating mutual attraction between it and the driving magnetic component 107, so that the slider 106 can be tightly attached to the corresponding guide post 110), used to cooperate with the driving magnetic component 107 to attract and support the slider 106 against the bottom surface of the side cavity.

[0067] See Figure 7 Furthermore, the aforementioned slider 106 may include a slider 106 body and a magnetic baffle 112. The magnetic baffle 112 is embedded in the slider 106 body and is arranged on the side of the driving magnetic component 107 facing the lens zoom assembly 2 (i.e., the magnetic baffle 112 is arranged between the driving magnetic component 107 and the lens zoom assembly 2). In order to ensure that the bottom magnetic absorbing piece 111 can still function, the magnetic baffle 112 may have a magnetic absorbing piece clearance hole 1065 corresponding to the bottom magnetic absorbing piece 111.

[0068] In this embodiment, to achieve stepless adjustment, the periscope module may further include a detection unit 113, which is configured to detect and feedback the sliding displacement of the slider 106. Specifically, the detection unit 113 may be mounted on the plate-shaped cover body, preferably at the center of the drive coil 108.

[0069] Specifically, the detection unit 113 can be a sensor that detects the sliding displacement of the slider 106. After acquiring the detection data, the external control chip controls the coil current to rotate the rotating component to a specified position, i.e., the blade 103 opens or closes to a specified aperture. Alternatively, the detection unit 113 can be a Hall effect chip, which has its own control function. It detects and feeds back the sliding displacement of the slider 106, controls the coil current, and causes the slider 106 to slide to a specified position.

[0070] In order to minimize the increase in the overall size of the device, in this embodiment, the side wall of the mounting cover and the side wall of the connecting housing 109 are fitted together to form a circuit accommodating space (specifically, the side wall of the mounting cover and the side wall of the connecting housing 109 corresponding to the long side mentioned above). The circuit accommodating space extends toward each drive coil 108, and the mounting cover and / or the connecting housing 109 are provided with a circuit opening that connects to the circuit accommodating space. The circuit opening extends through to the side of the connecting housing 109 facing the lens zoom assembly 2.

[0071] It also includes a first electrical connector 105, which may be an FPC, arranged in the circuit housing space. The input end of the first electrical connector 105 extends backward and is configured to protrude from the circuit opening. The output end of the first electrical connector 105 extends along the long side to both sides to the short side, and then connects to the corresponding two drive coils 108 on the mounting cover.

[0072] Furthermore, it also includes a second electrical connector (which may be an FPC or an insert-molding component), which may be configured to be at least partially embedded in the lens zoom assembly 2, and the output end of the second electrical connector is arranged facing the circuit opening of the variable aperture assembly 1 for electrical connection with the first electrical connector 105 extending from the circuit opening.

[0073] See Figure 4 In this embodiment, in order to adjust the light-transmitting aperture under radial drive, the blade 103 may specifically include a sliding connecting section, a rotating connecting section and an aperture forming section connected in sequence.

[0074] The sliding connection section is provided with a groove for sliding connection with the corresponding sliding column 1062 on the sliding member 106. The rotating connection section is provided with a rotating hole for rotating connection with the corresponding rotating column 1094 on the variable aperture housing (the rotating column 1094 is specifically arranged vertically on the blade support platform). The groove is configured to drive the sliding connection section and the aperture forming section to swing relative to the rotating column 1094 under the radial drive of the sliding column 1062 (the groove is specifically a long strip through groove, the extension direction of the long strip through groove is inclined to the above-mentioned radial direction, and each blade group can include two blades 103, the extension direction of the groove of the two blades 103 is symmetrically arranged relative to the sliding direction of the sliding member 106).

[0075] Furthermore, a shim 104 can be provided on the blade support platform, and the blade 103 is specifically arranged on the shim 104, which is coated with an anti-reflective film.

[0076] Furthermore, the plastic top cover 102 can also have clearance holes corresponding to the sliding column 1062 and the rotating column 1094, thereby further reducing the overall thickness of the device and preventing the blades from slipping out.

[0077] In this embodiment, to further reduce the overall length of the device along the optical axis, the variable aperture housing may be further configured to include an aperture blade region and a lens receiving region arranged along the optical axis, as well as two blade driving regions located radially on both sides of the lens receiving region. A first blade group and a second blade group are arranged in the aperture blade region, and a first driving assembly and a second driving assembly are respectively arranged in the two blade driving regions. The lens receiving region is fitted onto at least a portion of the lens zoom assembly 2 along the optical axis.

[0078] The first and second drive components of the variable aperture assembly 1 are set on the outside of the lens zoom assembly 2, so that after the variable aperture assembly 1 is connected to the lens zoom assembly 2, the length change in the optical axis direction is only the sum of the thickness of the lens zoom assembly 2 and the aperture blade area and the thickness of the variable aperture housing corresponding to that area. The overall length change is not significant, the device is miniaturized, and the problem of integrating variable aperture in existing periscope modules due to size constraints is solved.

[0079] Furthermore, since the fixed part of the lens group 201 of the lens zoom assembly 2 occupies a smaller volume than the moving part of the lens group 202, the driving part of the blade 103 can be arranged in the space outside the fixed part of the lens group 201. Thus, under the premise of integrating the variable aperture into the periscope module, the overall volume of the variable aperture assembly 1 and the lens zoom assembly 2 after connection does not change much, thereby achieving the miniaturization of the entire device.

[0080] Furthermore, the aforementioned connecting housing 109 may specifically include a connecting base plate 1091 with an accommodating opening (allowing light to pass through), a plurality of accommodating wall plates 1092, and a blade support plate. The bottom ends of the plurality of accommodating wall plates 1092 are respectively connected to the edges of the accommodating openings. Each accommodating wall plate 1092 is arranged parallel to the optical axis, i.e., multiple accommodating wall plates 1092 are arranged sequentially around the optical axis circumferentially. The sides of the accommodating wall plates 1092 can be connected to form a closed shape, or the accommodating wall plates 1092 can be spaced apart to satisfy the circumferential limiting of the lens accommodating area described above. The blade support plate is arranged perpendicular to the optical axis and is connected to the top of each accommodating wall plate 1092 (i.e., the blade support plate and the connecting base plate 1091 are parallel, and the accommodating wall plates 1092 are arranged between them).

[0081] The accommodating opening, each accommodating wall plate 1092, and the blade support plate work together to form a lens accommodating area with the opening facing rearward (i.e., towards the lens zoom assembly 2).

[0082] An aperture blade area is formed between the blade support plate and the plate-shaped cover body of the mounting cover (the plate-shaped cover body has through holes for light to pass through), and the surface of the blade support plate facing the mounting cover is the aforementioned blade support platform. The radially outward surface of the receiving wall plate 1092 cooperates with the connecting housing 109 to form a blade driving area (the radially outward surface of the receiving wall plate 1092 can be specifically set to be parallel to the short side side, and then cooperates with the corresponding short side side and the two long side sides between them to form the blade driving area, which is the aforementioned side chamber).

[0083] See Figure 8Furthermore, corresponding lateral magnetic absorbing pieces 114 can also be provided (attached or embedded) on the radially outward surface or short side of the receiving wall panel 1092, in conjunction with the driving magnetic component 107, so that the positions of the sliding components 106 on both sides are consistent in the initial state (i.e., the power-off state), at which time the aperture is opened to the maximum or minimum state.

[0084] In this embodiment, the surface of the connecting base plate 1091 facing the lens zoom assembly 2 may be provided with a plurality of first snap-fit ​​structures (specifically, snap-fit ​​grooves 1095, the number of which may be four, arranged around the aforementioned receiving opening, and may be located at the edge of the connecting base plate 1091), and the surface of the lens zoom assembly 2 facing the connecting base plate 1091 may be provided with a plurality of second snap-fit ​​structures (specifically, snap-fit ​​blocks 203). Of course, in other embodiments, the connecting base plate 1091 and the lens zoom assembly 2 may also be configured as a positioning and adhesive connection, or a combination of snap-fit ​​grooves and adhesive, which is not specifically limited here.

[0085] In this embodiment, the above-mentioned mounting housing, connecting housing 109, sliding member 106 and other structures can all be strengthened by embedding metal parts. Furthermore, embedding metal parts can also make the corresponding structure thinner and have the function of balancing the center of gravity.

[0086] In this embodiment, the lens zoom assembly 2 may specifically include a fixed base with a fixed portion of the lens group 201 and a movable base with a movable portion of the lens group 202. The movable base moves relative to the fixed portion of the lens group 201 along the optical axis via a sliding shaft. The driving force may be the thrust generated by the magnet fixed on the movable base and the corresponding coil. Of course, the driving method of the periscope lens may mainly include: spring type, suspension wire type, sliding shaft type, and ball bearing type, which are not specifically limited here. In order to further avoid the influence of the driving magnet on the variable aperture assembly 1 on the lens zoom assembly 2, a magnetic blocking plate 112 may be provided on the housing of the lens zoom assembly 2, or the housing may be made of a magnetic metal material to block the magnetism.

[0087] Example 2

[0088] This embodiment provides a camera module, including the periscope module with integrated variable aperture as described in Embodiment 1 above. The variable aperture assembly 1 is arranged to connect to the lens zoom assembly 2 along the optical axis. The variable aperture assembly 1 is configured as a variable aperture housing and includes a first drive assembly, a second drive assembly, a first blade group, and a second blade group arranged within the housing. The first and second blade groups are arranged on opposite sides of the optical axis radially. The first and second drive assemblies are respectively arranged corresponding to the first and second blade groups. Both the first and second drive assemblies are configured to output radial drive motion and transmit it to the blades 103 of the corresponding blade groups. The blades 103 are configured to rotate relative to the variable aperture housing under radial drive, thereby creating light-transmitting holes of different diameters. By changing the driving method of the blades 103 from conventional rotating component drive to radial drive, the thickness of the drive assembly in the optical axis direction can be effectively reduced, thereby reducing the thickness of the variable aperture assembly 1 in the optical axis direction. This results in minimal change in the overall length formed by the variable aperture assembly and the lens zoom assembly 2, minimizing the overall size of the device and solving the problem of integrating a variable aperture in existing periscope modules due to size constraints.

The first and second drive assemblies are respectively arranged corresponding to the first and second blade groups. Both the first and second drive assemblies are configured to output radial drive motion and transmit it to the blades 103 of the corresponding blade groups. The blades 103 are configured to rotate relative to the variable aperture housing under radial drive, thereby creating light-transmitting holes of different diameters.
