Description

Technical Field

[0001] The utility model relates to the field of curved surface long - focal - length driving devices, and particularly to a curved surface long - focal - length driving device, a camera and an electronic device. Background Art

[0002] In the existing periscope - type structure design, the elastic sheet is usually arranged on the side or at a 45 - degree inclined position. This layout brings an obvious challenge when assembling the elastic sheet and the OIS (Optical Image Stabilizer) carrier: an inevitable flipping operation is required during the assembly process. This step not only increases the complexity of manual labor but also seriously hinders the realization of automated assembly. The difficulty of automated assembly mainly stems from the fact that the flipping action is difficult to be accurately simulated by a robotic arm or other automated devices, which leads to a reduction in production efficiency, an increase in production costs, and an increase in the risk of product damage during the production process. Although the horizontal placement scheme of the OIS spring can solve the above problems, due to the traditional periscope - type structure, its anti - shake direction is Pitch + Yaw (pitch + yaw). If the OIS spring adopts the horizontal placement scheme, the OIS spring needs to be customized and produced with a special width - thickness ratio design, increasing additional production costs. Summary of the Utility Model

[0003] In view of this, the utility model provides a curved surface long - focal - length driving device, a camera and an electronic device. The innovative design of the curved surface long - focal - length driving device, through the horizontal arrangement of the OIS spring and the optimization of the prism curved surface, not only simplifies the assembly process, improves production efficiency, but also effectively reduces costs and improves product quality.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A curved surface long - focal - length driving device includes a base, a housing, a prism carrier, an OIS spring and OIS balls for supporting the prism carrier, an OIS magnet and an OIS coil for driving the prism carrier, an AF carrier, AF balls for supporting the AF carrier, an AF magnet and an AF coil for driving the AF carrier. The OIS spring is horizontally placed on the base and contacts the bottom of the prism carrier. The prism carrier is equipped with a prism, and the prism is provided with a first curved surface and a second curved surface.

[0006] The horizontal arrangement of the OIS spring enables the prism carrier to be directly inserted into the base from above without complex flipping operations. This intuitive assembly method greatly simplifies the assembly steps and makes automated assembly possible. The realization of automated assembly not only improves production efficiency but also significantly reduces manual intervention, thereby reducing the error rate and rework rate caused by human factors.

[0007] The first surface and the second surface are provided on the prism in the device. The innovation of this design lies in that it changes the anti-shake direction of the OIS spring on the prism, from the traditional Pitch+Yaw to Pitch+Roll. This change not only optimizes the anti-shake effect but also enables the OIS spring to adopt a conventional width-to-thickness ratio without the need for a customized special spring design. Springs with a conventional width-to-thickness ratio are not only easier to obtain but also reduce the manufacturing cost and improve the overall economy. This innovation in design fully reflects the dual considerations of device performance and cost control, demonstrating the pursuit of balance between efficiency and economy in modern optical device manufacturing.

[0008] The innovative design of the curved surface telephoto drive device, through the horizontal arrangement of the OIS spring and the optimization of the prism curved surface, not only simplifies the assembly process, improves production efficiency, but also effectively reduces costs, bringing a qualitative leap to the manufacturing of optical devices. These series of design and technological breakthroughs not only demonstrate the innovative vitality in the field of modern optical manufacturing but also inject new impetus into the development of the industry, indicating the arrival of an era of more efficient, more economical, and higher-performance optical device manufacturing. Through continuous technological innovation and process optimization, future optical devices will be able to better meet the market and consumers' demands for high-quality and high-performance products, promoting the entire industry to develop towards a higher-end and more precise direction.

[0010] The first surface and the second surface of the prism are arranged along the direction of the optical channel line of the prism, ensuring that the light can propagate stably along the preset path when passing through the prism, effectively avoiding image distortion caused by the deviation of the light path. The distance between the first surface and the AF carrier along the direction of the optical channel line is less than the distance between the second surface and the AF carrier along the direction of the optical channel line. This differential layout can precisely adjust the propagation path of the light between the prism and the AF carrier (automatic focusing carrier), realizing the fine control of image stability and significantly improving the image stabilization effect and overall performance of the device.

[0011] Preferably, the first surface is recessed inward and the second surface is convex outward.

[0012] The first surface is recessed inward, while the second surface is convex outward. This special design not only optimizes the light propagation path within the prism but also effectively improves the image quality and the economy of the device. The design of the first surface being recessed inward can effectively focus light, reduce light scattering, and improve the clarity and contrast of the image. The design of the second surface being convex outward can further optimize the refraction angle of light, ensure that the light is evenly and stably projected onto the imaging sensor, avoid the phenomenon of blurred image edges or uneven brightness, and significantly improve the overall quality of the image.

[0013] Preferably, the plane where the OIS spring is located forms mutually orthogonal X-axis and Z-axis, and the Y-axis is perpendicular to the plane where the OIS spring is located. The anti-shake directions of the prism are the X-axis and the Z-axis.

The anti-shake direction of the prism is along the X-axis and the Z-axis directions, achieving precise control of the anti-shake effect. It can avoid the decentration of the position of the field spot, thus avoiding the phenomenon of resolution degradation, and can effectively improve the optical imaging quality.

[0015] Preferably, a hemispherical groove is dug at the center of the bottom of the prism carrier. A part of the OIS ball is fitted with the hemispherical groove. A hollow is provided in the middle of the OIS spring. A part of the OIS ball passes through the hollow and contacts the base.

A hollow is provided in the middle of the OIS spring. A part of the OIS ball passes through the hollow and contacts the base. This precise matching design not only ensures the stable support of the prism carrier but also realizes the flexible movement of the anti-shake system through the contact between the OIS ball and the base, ensuring the image stability of the device in a vibrating or moving environment. In addition, the design of the hemispherical groove can effectively disperse the weight of the prism carrier, reduce local stress, and improve the structural stability and service life of the device.

[0017] Preferably, the prism carrier is provided with an inclined surface, and a prism is installed on the inclined surface. An OIS groove is dug on the side surface of the prism carrier, and the OIS magnet is embedded in the OIS groove. There are three OIS grooves, namely the first groove on the left side of the inclined surface, the second groove on the right side of the inclined surface, and the third groove on the back of the inclined surface.

[0018] The prism carrier is provided with an inclined surface, on which a prism is mounted. An OIS groove is dug on the side surface of the prism carrier, and an OIS magnet is embedded in the OIS groove. This integrated design not only optimizes the internal layout of the device, reduces the volume and weight of the device, but also realizes precise control of the prism movement by closely combining the OIS magnet with the prism carrier, improving the image stabilization effect. In particular, there are three OIS grooves, namely the first groove located on the left side of the inclined surface, the second groove located on the right side of the inclined surface, and the third groove located on the back of the inclined surface.
