Description

Periscope module, camera module and electronic equipment with integrated variable aperture Technical Field

[0001] The present invention belongs to the field of camera technology, and in particular relates to a periscope module with integrated variable aperture, a camera module and an electronic device. Background Art

[0002] The aperture size of a mobile phone camera is an important factor affecting the photo quality. A large aperture camera has a large aperture, allowing more light to enter the camera module, shortening the shutter time, making it suitable for shooting moving objects. At the same time, it has a shallow depth of field and can also be used in scenes such as blurring the background and highlighting the subject. A small aperture camera has a longer shutter time and is suitable for shooting car tracks and star trails, etc. At the same time, it has a deep depth of field, ensuring the clarity of objects within multiple depth of field ranges.

[0003] Compared to the zoom capabilities of traditional cameras, periscope cameras offer powerful optical zoom capabilities, such as a maximum 10x optical zoom, which has led to their gradual adoption in the mobile phone industry. However, existing technologies make it difficult to adjust the aperture size of periscope cameras in multiple levels to change the incident light intensity and depth of field, which in turn affects the shooting effect and limits their scope of use.

[0004] Publication No. CN113867074A provides a technical solution for setting a variable aperture on a periscope lens. The variable aperture is rotated by a motor-driven lead screw, which drives the nut slider and the light-shielding blades located on the nut slider to perform linear motion to achieve aperture changes. The problem is that the adjustment range and effect are limited. At the same time, the use of a motor drive occupies a large space, which is not conducive to the miniaturization of the periscope module. The technical solution provided by Publication No. CN110677565A is to set a variable aperture on the prism assembly. On the one hand, setting a variable aperture on the light-entering surface of the prism assembly will affect the overall height / thickness of the periscope module, which is not conducive to the thinning of the camera module. On the other hand, when the prism assembly has an anti-shake drive function, the setting and adjustment of the variable aperture on the prism assembly will be quite difficult.

DETAILED DESCRIPTION

[0046] The following is a detailed description of a periscope module, camera module, and electronic device with an integrated variable aperture proposed by the present invention, with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description and claims.

[0047] Example 1

[0048] 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 in the variable aperture housing.

[0050] The first blade group and the second blade group are respectively arranged on opposite sides of the optical axis in a radial direction. The blades 103 in the first blade group and the blades 103 in the second blade group jointly enclose a light-transmitting aperture. The first drive assembly and the second drive assembly are respectively arranged on opposite sides of the optical axis in a radial direction. The first drive assembly corresponds to the first blade group, and the second drive assembly corresponds to the second blade group. The first drive assembly and the second drive assembly are respectively configured to output radial motion to the blades 103 in the first blade group and the blades 103 in the second blade group. The blades 103 are configured to rotate relative to the variable aperture housing under radial drive, thereby changing the aperture of the light-transmitting aperture enclosed by the plurality of blades 103.

[0051] This embodiment arranges the variable aperture assembly 1 so as to be connected to the lens zoom assembly 2 along the optical axis. The variable aperture assembly 1 is provided as a variable aperture housing, and a first drive assembly, a second drive assembly, a first blade group, and a second blade group are arranged within the variable aperture housing. The first blade group and the second blade group are arranged radially opposite the optical axis, and the first drive assembly and the second drive assembly are arranged corresponding to the first blade group and the second blade group, respectively. The first drive assembly and the second drive assembly are each configured to output radial drive motion and transmit it to blades 103 of the corresponding blade group. The blades 103 are configured to rotate relative to the variable aperture housing under radial drive, thereby forming light-transmitting apertures of varying aperture diameters. By changing the drive method of the blades 103 from conventional rotating element drive to radial drive, the thickness of the drive assembly along the optical axis can be effectively reduced, thereby reducing the thickness of the variable aperture assembly 1 along the optical axis. This reduces the overall length of the variable aperture assembly 1 and the lens zoom assembly 2, and reduces the overall thickness (height) of the device, thereby resolving the problem of the difficulty of integrating a variable aperture into existing periscope modules due to volume constraints.

[0052] Furthermore, in this embodiment, the blade assembly and the drive assembly are respectively arranged on opposite sides of the radial direction of the optical axis, so that the variable aperture assembly 1 as a whole will only extend in the radial direction. The thickness of the variable aperture assembly 1 in the direction of the optical axis and the width perpendicular to the optical axis and in the radial direction can be controlled to be very small, thereby achieving the miniaturization of the entire device.

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

[0054] In this embodiment, both the first driving assembly and the second driving assembly may include a sliding member 106 and a driving member.

[0055] Specifically, the slider 106 can be arranged to be radially slidably connected to the iris diaphragm housing, with the output ends of the slider 106 configured to be slidably connected to corresponding blades 103 (i.e., the number of output ends on the slider 106 matches the number of blades 103 in the corresponding blade assembly). The driver is disposed within the iris diaphragm housing and configured to drive the corresponding slider 106 to slide radially. In other embodiments, the second drive assembly may not be an independent drive structure, but may be a transmission structure connected to the first drive assembly, thereby outputting radial motion on the other side under the drive of the first drive assembly. This is not specifically limited here.

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

[0057] Furthermore, the driving magnetic part 107 can be specifically a driving magnet, including a monopole magnet, a multi-stage magnet or a Halbach array magnet. The installation method can be to open a mounting groove on the sliding part 106 and embed the driving magnet into the mounting groove, or it can be set to be integrally formed with the sliding part 106.

[0058] In this embodiment, the iris iris housing may specifically include a mounting cover and a connecting housing 109. The mounting cover engages with the connecting housing 109 to form a chamber for mounting the drive assembly and blade assembly. The connecting housing 109, facing the mounting cover, is provided with 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. The aforementioned slider 106 is radially slidably connected to the side chambers, while the drive coil 108 is mounted in the side chambers or on the mounting cover.

[0059] Specifically, the outer shape of the mounting cover can be set to a rectangular parallelepiped, including a rectangular plate-shaped cover body and four rectangular walls surrounding the plate-shaped cover body; similarly, the connecting shell 109 is also a rectangular parallelepiped, and the mounting cover is arranged on the connecting shell 109 to form a variable aperture assembly 1 in the shape of a rectangular parallelepiped. The variable aperture assembly 1 of the rectangular parallelepiped may specifically include two short side surfaces and two long side surfaces parallel to the optical axis direction, and the short side surfaces are perpendicular to the above-mentioned radial direction.

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

[0061] Among them, the radial guide structure is a guide column 110 arranged on the bottom surface of the side chamber (two long grooves can be opened on the bottom surface of the side chamber, and the guide column 110 is placed in the groove and at least part of the guide column 110 extends out of the bottom surface of the side chamber to play a guiding role. The guide column 110 can also be directly integrally formed with the connecting shell 109), or the radial guide structure is a plurality of rollers or balls arranged radially on the bottom surface of the side chamber (the arrangement form is also to open two long grooves on the bottom surface of the side chamber, and the rollers or balls are arranged in the groove and at least partially extend out of the bottom surface of the side chamber).

[0062] 6 , the two guide engagement structures described above can be respectively a positioning guide groove 1063 and a mating allowance guide groove 1064 provided on the bottom surface of the sliding member 106. Specifically, the positioning guide groove 1063 can be a V-shaped groove, which, when mated with the corresponding guide post 110 or roller, defines their relative position; while the mating allowance guide groove 1064 can be a flat groove or a U-shaped groove, providing a partial mating allowance. If both are V-shaped grooves, differences in machining precision could result in the two slide shafts becoming stuck or becoming difficult to assemble.

[0063] Referring to Figure 3, in this embodiment, since the driving magnetic part 107 is installed on the sliding part 106, and the bottom surface of the side chamber needs to be used as a mating surface for sliding connection, the above-mentioned driving coil 108 can be set on the installation cover and arranged toward the sliding part 106. The specific positioning method is to position and install it on the installation cover through the coil positioning column 1021. In order to prevent the sliding part 106 from hitting the driving coil 108 upward when it is impacted by external force, in this embodiment, the bottom end of the coil positioning column 1021 is set to extend from the surface of the driving coil 108 facing the sliding part 106, that is, when the sliding part 106 hits upward, it hits the bottom end surface of the coil positioning column 1021, preventing the sliding part 106 and the driving magnetic part 107 thereon from directly colliding with the driving coil 108.

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

[0065] Referring to Figure 5, in this embodiment, in order to prevent the sliding member 106 from hitting the plastic upper cover 102 under the action of external force and causing damage or deformation to the plastic structure, at least one protective boss 1061 can be provided on the surface of the sliding member 106 facing the mounting cover, and the protective boss 1061 extends toward the mounting end cover along the optical axis direction (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 in the optical axis direction to avoid the driving coil 108 to avoid hitting the driving coil 108; and a avoiding groove can be provided on the plastic upper cover 102 corresponding to 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 sliding member 106, the periscope module with integrated variable aperture may also include a bottom magnetic attraction sheet 111 arranged on the connecting shell 109 (specifically, it can be arranged on the bottom surface of the connecting shell 109, that is, the surface of the connecting shell 109 facing the lens zoom assembly 2; specifically, it can be installed by opening a recessed groove, sticking or embedding, and generating mutual attraction between the driving magnetic member 107, so that the sliding member 106 can be tightly attached to the corresponding guide column 110), which is used to cooperate with the driving magnetic member 107 to adsorb the sliding member 106 against the bottom surface of the side chamber.

[0067] Referring to FIG. 7 , the slider 106 may further include a slider body 106 and a magnetic shield 112. The magnetic shield 112 is embedded in the slider body 106 and arranged on the side of the drive magnetic member 107 facing the lens zoom assembly 2 (i.e., the magnetic shield 112 is arranged between the drive magnetic member 107 and the lens zoom assembly 2). To ensure that the bottom magnetic sheet 111 can still function, a magnetic shield retaining hole 1065 corresponding to the bottom magnetic sheet 111 may be formed in the magnetic shield 112.

[0068] In this embodiment, to achieve stepless adjustment, the periscope module may further include a detection unit 113, which is configured to detect and provide feedback on 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] The detection unit 113 can be a sensor that detects the sliding displacement of the slider 106. The external control chip obtains the detection data and controls the coil current to rotate the rotating member to a specified position, that is, the blades 103 open and close to a specified aperture. The detection unit 113 can also be a Hall effect chip, which has its own control function, that is, it detects the sliding displacement of the slider 106 and provides feedback, controls the coil current, and causes the slider 106 to slide to the specified position.

[0070] In order to minimize the increase in the overall volume of the device, in this embodiment, the side walls of the mounting cover and the side walls of the connecting shell 109 are matched to form a circuit accommodating space (specifically, the side walls of the mounting cover and the side walls of the connecting shell 109 corresponding to the above-mentioned long side surfaces), and the circuit accommodating space extends toward each driving coil 108, and a circuit opening connected to the circuit accommodating space is provided on the mounting cover and / or the connecting shell 109, and the circuit opening extends to the surface of the connecting shell 109 facing the lens zoom assembly 2.

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

[0072] Furthermore, a second electrical connector is included (which may be an FPC or an insert-molding component). The second electrical connector can be configured to be at least partially embedded in the lens zoom assembly 2, and the output end of the second electrical connector is configured to face the circuit opening of the variable aperture assembly 1, for electrically connecting to the first electrical connector 105 extending from the circuit opening.

[0073] 4 , in this embodiment, in order to achieve adjustment of the light-transmitting hole under radial drive, the blade 103 may specifically include a sliding connection section, a rotating connection section, and an aperture forming section that are sequentially connected.

[0074] A sliding groove is provided on the sliding connection section for sliding connection with the corresponding sliding column 1062 on the sliding member 106, and a rotating hole may be provided on the rotating connection section for rotation connection with the corresponding rotating column 1094 on the variable aperture housing (the rotating column 1094 is specifically arranged vertically on the blade bearing platform), and the sliding 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 sliding groove is specifically a long strip through groove, and the extension direction of the long strip through groove is inclined to the above-mentioned radial direction. Each blade group can include two blades 103, and the extension direction of the sliding grooves of these two blades 103 is symmetrically arranged relative to the sliding direction of the sliding member 106).

[0075] Furthermore, a gasket 104 may be provided on the blade supporting platform. The blade 103 is specifically arranged on the gasket 104 , and the gasket 104 is coated with an anti-reflection film.

[0076] Furthermore, avoidance holes corresponding to the sliding posts 1062 and the rotating posts 1094 may be provided on the plastic upper cover 102 , thereby further reducing the overall thickness of the device and preventing the blades from sliding out.

[0077] In this embodiment, to further reduce the overall length of the device along the optical axis, the iris housing can be further configured to include an aperture blade area and a lens housing area arranged along the optical axis, as well as two blade drive areas located radially on either side of the lens housing area. A first blade group and a second blade group are arranged in the aperture blade area, and a first drive assembly and a second drive assembly are respectively arranged in the two blade drive areas. The lens housing area is positioned along the optical axis to fit over at least a portion of the zoom lens assembly 2.

[0078] That is, the first drive assembly and the second drive assembly of the variable aperture assembly 1 are arranged 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 shell corresponding to the area. The overall length changes little, and the overall device is miniaturized, which solves the problem that the existing periscope module is difficult to integrate the variable aperture due to volume reasons.

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

[0080] Furthermore, the aforementioned connection housing 109 may specifically include a connection base plate 1091 having a receiving opening (the receiving opening allows light to pass through), a plurality of receiving wall plates 1092, and a blade support plate. The bottom ends of the plurality of receiving wall plates 1092 are respectively connected to the edges of the receiving opening, and each receiving wall plate 1092 is arranged parallel to the optical axis, i.e., a plurality of receiving wall plates 1092 are sequentially arranged circumferentially around the optical axis. The side edges of the receiving wall plates 1092 may be connected to form a closed pattern, or the receiving wall plates 1092 may be spaced apart to meet the circumferential limitation of the lens receiving area. The blade support plate is arranged perpendicular to the optical axis and is connected to the top ends of each receiving wall plate 1092 (i.e., the blade support plate is parallel to the connection base plate 1091, and the receiving wall plate 1092 is arranged therebetween).

[0081] The accommodating opening, each accommodating wall plate 1092 and the blade supporting plate cooperate to form a lens accommodating area with the opening facing rearward (ie, toward the lens zoom assembly 2 ).

[0082] The blade support plate and the plate-shaped cover body of the mounting cover form the aperture blade area (the plate-shaped cover body is provided with through-holes for light to pass through). The surface of the blade support plate facing the mounting cover serves as the aforementioned blade support platform. The radially outward surface of the receiving wall plate 1092 cooperates with the connecting housing 109 to form the blade drive area (the radially outward surface of the receiving wall plate 1092 can be specifically arranged parallel to the short side surface, and then cooperates between the corresponding short side surface and the two long side surfaces therebetween to form the blade drive area, which is the aforementioned side chamber).

[0083] Referring to Figure 8, further, a corresponding lateral magnetic sheet 114 can be provided (attached or embedded) on the radially outward surface or short side surface of the accommodating wall panel 1092 to cooperate with the driving magnetic component 107 so that the positions of the sliding components 106 on both sides are kept consistent in the initial state (i.e., in the power-off state), and 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 engaging structures (specifically, engaging grooves 1095, which may be four in number, arranged around the aforementioned receiving opening and located at the edge of the connecting base plate 1091). The surface of the lens zoom assembly 2 facing the connecting base plate 1091 may be provided with a plurality of second engaging structures (specifically, engaging blocks 203) for mating engagement. Of course, in other embodiments, the connecting base plate 1091 and the lens zoom assembly 2 may also be connected using a combination of positioning and gluing, or a combination of engaging grooves and gluing, which are not specifically limited herein.

[0085] In this embodiment, the above-mentioned mounting shell, connecting shell 109, sliding member 106 and other structures can all adopt the method of embedding metal parts to improve the structural strength, and the method of 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 zoom lens assembly 2 may specifically include a fixed base with a fixed lens group 201 and a movable base with a movable lens group 202. The movable base moves relative to the fixed lens group 201 along the optical axis via a sliding shaft. The driving force may be the thrust generated by the interaction between a magnet fixed to the movable base and a corresponding coil. Of course, periscope lens drive methods may include spring, suspension, sliding shaft, and ball bearing types, which are not specifically limited here. To further prevent the driving magnet on the variable aperture assembly 1 from affecting the zoom lens assembly 2, a magnetic shield 112 may be provided on the housing of the zoom lens assembly 2, or the housing may be constructed of a magnetic metal material to block magnetism.

[0087] Example 2

[0088] This embodiment provides a camera module, including the periscope module with an integrated variable aperture described in the first embodiment. The variable aperture assembly 1 is arranged to connect to the lens zoom assembly 2 along the optical axis, and the variable aperture assembly 1 is configured as a variable aperture housing, and a first drive assembly, a second drive assembly, a first blade group, and a second blade group are arranged within the variable aperture housing. The first blade group and the second blade group are arranged radially opposite the optical axis, and the first drive assembly and the second drive assembly are arranged corresponding to the first blade group and the second blade group, respectively. The first drive assembly and the second drive assembly are each configured to output radial drive motion and transmit it to blades 103 of the corresponding blade group. The blades 103 are configured to rotate relative to the variable aperture housing under radial drive, thereby defining light-transmitting apertures of varying apertures. By changing the drive method for the blades 103 from conventional rotating element drive to radial drive, the thickness of the drive assembly along the optical axis can be effectively reduced, thereby reducing the thickness of the variable aperture assembly 1 along the optical axis. This reduces the overall length of the variable aperture assembly 1 and the lens zoom assembly 2, resulting in a smaller overall device size. This solves the problem of conventional periscope modules being difficult to integrate with a variable aperture due to volume constraints.

[0089] Example 3

[0090] This embodiment provides an electronic device, including the camera module of the second embodiment described above. The variable aperture assembly 1 is arranged to be connected to the lens zoom assembly 2 along the optical axis, and the variable aperture assembly 1 is configured as a variable aperture housing, and a first drive assembly, a second drive assembly, a first blade group, and a second blade group are arranged within the variable aperture housing. The first blade group and the second blade group are arranged on opposite sides of the optical axis radially, and the first drive assembly and the second drive assembly are arranged corresponding to the first blade group and the second blade group, respectively. The first drive assembly and the second drive assembly are each configured to output radial drive motion and transmit it to blades 103 of the corresponding blade group. The blades 103 are configured to rotate relative to the variable aperture housing under radial drive, thereby enclosing light-transmitting apertures of varying aperture diameters. By changing the drive method of the blades 103 from conventional rotating member drive to radial drive, the thickness of the drive assembly along the optical axis can be effectively reduced, thereby reducing the thickness of the variable aperture assembly 1 along the optical axis, so that the overall length of the variable aperture assembly 1 and the lens zoom assembly 2 does not change much, and the overall device is miniaturized, solving the problem that existing periscope modules are difficult to integrate with the variable aperture due to volume constraints.
