Description

Technical Field

[0001] This utility model relates to the field of aperture blade driving technology for lenses, and more specifically, to an aperture drive motor, a camera module, and an electronic device. Background Technology

[0002] In mobile photography, the aperture size of a camera has a decisive impact on the final image quality. The aperture not only controls the amount of light entering the lens but also directly affects shutter speed and depth of field, thus determining the optimal shooting strategy for different scenarios. A large aperture design allows more light to enter, significantly improving shooting performance in low-light conditions, enabling faster shutter speeds, reducing motion blur, and making it suitable for capturing fast-moving objects. Furthermore, a shallower depth of field helps create beautiful background blur effects, enhancing the visual impact of the subject. In contrast, a small aperture ensures longer exposure times and a deeper depth of field, which is extremely advantageous for shooting static landscapes such as car trails and star trails in night scenes, ensuring that the entire image, from foreground to distant background, is rendered clearly.

[0003] In existing technologies, the VCM (voice coil motor) is the core component for aperture control. When current is applied to it, it generates force, thereby changing the diameter of the aperture formed by the blade assembly. However, to achieve aperture adjustment with a smaller diameter, the blade assembly usually needs to be re-arranged, which increases the thickness of the aperture drive device in the optical axis direction, resulting in an increase in the overall thickness of the camera module, which is not conducive to miniaturization design.

[0004] Therefore, the existing technology suffers from poor performance of the aperture drive motor in the camera device. Utility Model Content

[0015] Furthermore, the aperture drive motor also includes: at least one first magnetic clasp, the first magnetic clasp being disposed on the bottom surface of the base assembly corresponding to a drive magnet; and a second magnetic clasp, the second magnetic clasp being disposed on the side of the drive coil opposite to the drive magnet that is away from the drive magnet, corresponding to one of the drive magnets.

[0016] Furthermore, the aperture drive motor also includes at least two guide shafts, each corresponding to a drive magnet disposed on the circumferential outer wall of the support boss.

[0017] Furthermore, the two guide shafts are symmetrically arranged about the driving magnet; and / or the axis of the guide shaft is parallel to the optical axis.

[0018] Furthermore, the aperture drive motor also includes: a PCB board, which is disposed on the base assembly and the drive coil is disposed on the PCB board; and an embedded part, at least a portion of which is embedded inside the base assembly and is electrically connected to the PCB board.

[0020] According to another aspect of the present invention, an electronic device is provided, including the camera module described above.

[0021] Applying the technical solution of this utility model, the aperture drive motor in this application includes a base assembly, a rotating carrier, a blade assembly, and a drive assembly.

Furthermore, as the current flowing through the drive component changes, the rotation direction of the rotating carrier can be changed, thereby enabling adjustment of the aperture size formed by the blade assembly. Moreover, since the blade assembly is housed within the housing cavity of the rotating carrier, more installation space can be provided for the blade assembly within the internal space of the rotating carrier. This allows the blade assembly to have more blades, ensuring that it can form a smaller diameter aperture, thus increasing the aperture adjustment range, without affecting the miniaturized design of the aperture drive motor. Therefore, the aperture drive motor of this application effectively solves the problem of poor performance of aperture drive motors in existing camera devices. Attached Figure Description

[0037] To address the issue of poor performance of aperture drive motors in existing camera devices, this application provides an aperture drive motor, a camera module, and an electronic device.

[0038] The electronic device in this application can be a mobile phone, drone, action camera, etc. Furthermore, the electronic device in this application has the camera module described in this application, and the camera module has the aperture drive motor described below.

[0039] like Figures 1 to 8As shown, the aperture drive motor in this application includes a base assembly 10, a rotating carrier 20, a blade assembly 30, and a drive assembly 40. The base assembly 10 has a receiving space; at least a portion of the rotating carrier 20 is movably disposed within the receiving space, the rotating carrier 20 has a receiving cavity 21 and a first mounting opening 22 and an aperture opening 23 respectively communicating with the receiving cavity 21, the circumferential inner sidewall of the receiving cavity 21 has a first mounting surface 211, and a mounting space is formed between the first mounting surface 211 and the aperture opening 23; the blade assembly 30 is movably disposed within the receiving cavity 21, and the blade assembly 30 is respectively connected to the first mounting surface 211 and the base assembly 10; at least a portion of the drive assembly 40 is disposed on the base assembly 10, and at least another portion of the drive assembly 40 is correspondingly disposed on the rotating carrier 20.

[0040] When using the aperture drive motor of this application, after the drive component 40 is energized, since at least a portion of the drive component 40 is disposed on the rotating carrier 20, the drive component 40 can drive the rotating carrier 20 to rotate relative to the base assembly 10. During the rotation of the rotating carrier 20, the blade assembly 30 can also rotate relative to the base assembly 10. Furthermore, as the current flowing through the drive component 40 changes, the rotation direction of the rotating carrier 20 can be changed, thereby enabling adjustment of the aperture size formed by the blade assembly 30. Moreover, since the blade assembly 30 is disposed within the receiving cavity 21 of the rotating carrier 20, more installation space can be provided for the blade assembly 30 through the internal space of the rotating carrier 20. This allows the blade assembly 30 to have more blades, ensuring that the blade assembly 30 can form a smaller diameter aperture, thereby increasing the aperture adjustment range, without affecting the miniaturized design of the aperture drive motor. Therefore, the aperture drive motor of this application effectively solves the problem of poor performance of aperture drive motors in existing camera devices.

[0041] Specifically, the blade assembly 30 includes a plurality of blade bodies 31, which are divided into multiple groups. Each group of blade bodies 31 includes at least two blade bodies 31 that are centrally symmetrically arranged about the rotation center of the rotating carrier 20.

[0042] Optionally, the blade bodies 31 of different groups have different heights along the optical axis. Optionally, all blade bodies 31 of the same group have the same height along the optical axis. In other words, all blade bodies 31 of the same group are located in the same plane, while blade bodies 31 of different groups are located in different planes, and the plane here refers to the plane perpendicular to the optical axis.

[0043] In one specific embodiment of this application, the blade bodies 31 in different groups have different heights along the optical axis. All blade bodies 31 in the same group have the same height along the optical axis. That is, in this embodiment, multiple blade bodies 31 are not only arranged circumferentially around the optical axis, but also spaced apart along the optical axis. By designing the arrangement of the blade bodies 31, the blade assembly 30 can be composed of a larger number of blade bodies 31, thereby enabling the blade assembly 30 to form a smaller diameter aperture under the adjustment action of the drive assembly 40.

[0044] In other words, the aperture drive motor in this application can achieve a miniaturized design while ensuring that it has more blade bodies 31.

[0045] Optionally, in the optical axis direction, the bottom surface of the rotating carrier 20 has a first mounting opening 22, and the top surface of the rotating carrier 20 has an aperture opening 23. This arrangement ensures that the blade assembly 30 can be more easily installed into the interior of the rotating carrier 20.

[0046] Preferably, the distance from the first mounting surface 211 to the first mounting opening 22 is less than the distance from the first mounting surface 211 to the aperture opening 23. This arrangement ensures that the interior of the rotating carrier 20 provides more mounting space for the blade assembly 30, allowing the blade assembly 30 to be higher or thicker in the optical axis direction. In other words, the blade assembly 30 can have multiple layers of blade bodies 31 in the optical axis direction, enabling the blade assembly 30 in this application to form an aperture with a smaller diameter. This improves the adjustment range of the aperture diameter of the blade assembly 30, thereby enhancing the performance of the aperture drive motor.

[0047] In one specific embodiment of this application, the rotating carrier 20 includes a body portion 24 and a top cover 25. The body portion 24 has a receiving cavity 21 and a first mounting opening 22, and the end of the body portion 24 away from the first mounting opening 22 has a second mounting opening 241. The top cover 25 has an aperture opening 23. The top cover 25 covers the second mounting opening 241; or the top cover 25 extends into the receiving cavity 21 through the second mounting opening 241 and is connected to the circumferential inner sidewall of the receiving cavity 21. By providing the top cover 25, the top cover 25 can limit and protect the blade assembly 30, thereby preventing the blade assembly 30 from displacing in the optical axis direction during movement.

[0048] Optionally, the circumferential inner wall of the receiving cavity 21 has an annular mounting flange 212, and the side of the mounting flange 212 facing the aperture opening 23 has a first mounting surface 211. This arrangement can effectively reduce the installation difficulty of the blade assembly 30.

[0049] Optionally, the base assembly 10 is provided with a support boss 11 facing the first mounting opening 22. At least a portion of the support boss 11 extends into the receiving cavity 21 through the first mounting opening 22, and the support boss 11 is provided with a second mounting surface 111 corresponding to the blade assembly 30. The blade assembly 30 is connected to the second mounting surface 111.

[0050] In one specific embodiment of this application, the blade assembly 30 includes a plurality of blade bodies 31, which are arranged circumferentially around the optical axis. A first mounting surface 211 is provided with a plurality of guide posts 2111 corresponding to the plurality of blade bodies 31, and a second mounting surface 111 is provided with a plurality of positioning posts 1111 corresponding to the plurality of blade bodies 31. Each blade body 31 has a guide opening 311 that cooperates with the guide posts 2111, and a positioning opening 312 that cooperates with the positioning posts 1111. In this application, the cooperation between the guide posts 2111 and the guide openings 311 ensures that the rotating carrier 20 can drive the blade bodies 31 to rotate relative to the base assembly 10. The cooperation between the positioning posts 1111 and the positioning openings 312 ensures that the blade assembly 30 can move relative to the base assembly 10 while maintaining connection with the base assembly 10. Therefore, when the rotating carrier 20 drives the blade assembly 30 to rotate relative to the base assembly 10, the positioning posts 1111 move relative to the positioning openings 312.

[0051] Optionally, the drive assembly 40 includes at least two drive coils 41 and at least two drive magnets 42. The two drive coils 41 are disposed opposite each other on the circumferential inner sidewall of the base assembly 10; the drive magnets 42 are disposed corresponding to the drive coils 41 on the circumferential inner sidewall of the rotating carrier 20. Therefore, when the drive coils 41 are energized, the drive coils 41 and the drive magnets 42 generate an interaction force, thereby causing the drive magnets 42 to drive the rotating carrier 20 to move.

[0052] Optionally, the aperture drive motor further includes: at least one first magnetic chuck 50, which is disposed on the bottom surface of the base assembly 10 corresponding to the drive magnet 42; and a second magnetic chuck 60, which is disposed on the side of the drive coil 41 opposite to the drive magnet 42, away from the drive magnet 42. Furthermore, the aperture drive motor also includes at least two guide shafts 70, which are disposed on the circumferential outer wall of the support boss 11 corresponding to the other drive magnet 42. In this application, by providing the first magnetic chuck 50, the rotating carrier 20 can rest against the bottom surface of the base assembly 10 under the mutual support of the drive magnet 42 and the first magnetic chuck 50, thereby ensuring the stability of the blade assembly 30. By providing the second magnetic chuck 60, it is ensured that the rotating carrier 20 can contact the guide shaft 70, thereby reducing the frictional force experienced by the rotating carrier 20 during rotation.

[0053] Optionally, the two guide shafts 70 are symmetrically arranged about the driving magnet 42; alternatively, the axis of the guide shaft 70 is parallel to the optical axis. This arrangement not only ensures more stable force on the rotating carrier 20, but also prevents the rotating carrier 20 from deviating in the optical axis direction.

[0054] Optionally, such as Figure 2 and Figure 8 As shown, the aperture drive motor also includes: a PCB board 80, which is disposed on the base assembly 10, and the drive coil 41 is disposed on the PCB board 80; and an embedded part 90, at least a portion of which is embedded inside the base assembly 10 and electrically connected to the PCB board 80. By setting the PCB board 80, a stable electrical connection of the drive coil 41 can be effectively ensured. Furthermore, by setting the embedded part 90, electrical conduction of the PCB board 80 can be achieved, and the strength of the base assembly 10 can be effectively improved.

[0055] Specifically, such as Figure 2 As shown, a top cover 100 is provided on the side of the upper cover 25 away from the rotating carrier 20, and the top cover 100 is connected to the base assembly 10 to ensure the structural stability of the aperture drive motor. A first gasket 200 is provided on the side of the top cover 100 away from the upper cover 25, a second gasket 300 is provided between the upper cover 25 and the top cover 100, and a third gasket 400 is provided between the blade assembly 30 and the support boss 11. In this application, the first gasket 200 and the second gasket 300 can be made of an ultra-black coating material to improve the structural appearance quality and refinement of the aperture drive motor, and to eliminate the problem of light glare. The third gasket 400 can be made using a surface coating process to improve the smoothness of the third gasket 400, thereby reducing the friction when the blade body 31 rotates.

[0056] Furthermore, in this application, the aperture drive motor may also be equipped with a position detection element, which may be a Hall magnet or a Hall chip. By setting the position detection element, the rotational position of the rotating carrier 20 can be detected in real time, thereby enabling control over the magnitude and direction of the current flowing through the drive coil 41. Optionally, the position detection element is disposed on the circumferential inner wall of the top cover 100 or the base assembly 10.
