[0040] As smartphone photography demands evolve, traditional single periscope telephoto modules are gradually facing bottlenecks in zoom capabilities and image quality. On one hand, the single periscope structure is limited by optical path design, making it difficult to simultaneously achieve high-magnification zoom and a slim profile; on the other hand, users' growing demand for telephoto image quality and multi-focal-length coverage is prompting the industry to seek breakthrough solutions.

[0041] Therefore, the dual periscope module was developed. By innovatively stacking two periscope lenses and sharing a single reflecting prism, it achieves higher magnification lossless zoom (such as 10x and above) and a more compact body design. Its core technology lies in the combination of a beam-splitting prism and a dual-track opening and closing front imaging system, which significantly improves telephoto resolution and stability. This design not only solves the physical limitations of a single periscope module at the telephoto end, but also propels mobile imaging towards the professional level, becoming an important technological benchmark for high-end flagship phones.

[0042] refer to Figures 1-4 As shown, this application provides a camera module and electronic device to solve the problem of large size occupied by existing camera modules. The following description is in conjunction with the accompanying drawings.

[0043] The camera module provided in this application embodiment is referenced. Figure 1 , Figure 2 As shown, the device includes a housing 100, a first lens assembly 200, a first sensor 300, and a second sensor 500. The housing 100 forms a receiving space 110 for the light path to pass through. The first lens assembly 200 and the second sensor 500 are arranged sequentially along the light path direction of the housing 100. The first sensor 300 is movably disposed in the housing 100 and is adapted to switch between a first position and a second position. In the first position, the first sensor 300 is located between the first lens assembly 200 and the second sensor 500, and the first sensor 300 is located in the light emission direction of the first lens assembly 200. In the second position, the first sensor 300 is located outside the light emission direction of the first lens assembly 200.

[0044] For example, the housing 100 serves as the support and protective frame for the entire camera module, and its interior forms a receiving space 110. This receiving space 110 constitutes a complete optical path channel, ensuring that ambient light can be transmitted stably and without interference within the module. The first lens assembly 200 is fixedly disposed within the receiving space 110 of the housing 100. The first lens assembly 200 may consist of one or more lenses, responsible for converging, refracting, and correcting the incoming light to form a high-quality optical image.

[0045] The first sensor 300 is movably disposed within the housing 100, and the first sensor 300 can be moved to a first position or a second position as needed.

[0046] Specifically, when the first sensor 300 moves to the first position, it is precisely positioned between the first lens assembly 200 and the second sensor 500, with its photosensitive surface facing the light emission direction of the first lens assembly 200. After external light enters the receiving space 110 of the housing 100, it is converged and processed by the first lens assembly 200, causing the light to no longer continue along its original path but instead be directly projected onto the photosensitive surface of the first sensor 300. At this time, the first sensor 300 acts as an imaging unit, responsible for converting the received light signal into an electrical signal to generate an image. The second sensor 500, located behind it, does not participate in imaging and remains idle. This mode can be set to a medium-long focal length mode, such as 3X or 4X.

[0047] When the first sensor 300 moves to the second position, it completely exits the light emission path of the first lens assembly 200. For example, it can be moved to the second position by translation, flipping, or extension to clear the light path. External light enters the receiving space 110 and, after being processed by the first lens assembly 200, its light path is no longer blocked by the first sensor 300. The light can then continue to propagate unimpeded along its original path, ultimately projecting onto the photosensitive surface of the second sensor 500. At this point, the second sensor 500 begins to function as an imaging unit, generating an image. The first sensor 300 remains idle. This mode can be set to a high-magnification telephoto mode, such as 5X, or even 10X or higher.

[0048] Understandably, traditional dual periscope camera modules require two complete and independent optical systems with parallel optical paths, resulting in a relatively large overall size. This application achieves equivalent focal length switching and zoom functions by sharing a single optical path and moving the first sensor 300 to different positions. This satisfies the zoom function of the camera module while significantly reducing internal space requirements, thereby substantially decreasing the overall size of the camera module and facilitating a thinner and lighter design.

[0049] In one optional implementation, combined with Figure 1 and Figure 2 As shown, the camera module also includes a rotating component 600, which is connected to the first sensor 300 to drive the first sensor 300 to rotate and switch the first sensor 300 between a first position and a second position.

[0050] Optionally, the rotating assembly 600 can drive the rotation of the first sensor 300 by means of gears, movable hinges, or suspension wires. When the camera module needs to switch zoom levels (e.g., from medium telephoto to telephoto), the control system issues a command, the rotating assembly 600 starts, and drives the first sensor 300 to rotate smoothly and quickly from the first position to the second position by a preset rotation angle (e.g., 90 degrees or 180 degrees). Conversely, when it is necessary to switch back from telephoto to medium telephoto, the rotating assembly 600 drives in the opposite direction, so that the first sensor 300 is accurately reset from the second position to the first position.

[0051] Understandably, the rotation method can improve the utilization rate of the storage space 110 compared to the translation method, and is more conducive to reducing the overall volume occupied.

[0052] In one optional implementation, combined with Figure 1 and Figure 2 As shown, the camera module also includes a second lens assembly 400, which is located between the first sensor 300 and the second sensor 500. When the first sensor 300 is in the second position, the light emitted from the first lens assembly 200 is emitted through the second lens assembly 400 and then reaches the second sensor 500.

[0053] In this embodiment, the second lens assembly 400 is an independent optical lens group, fixed between the first sensor 300 and the second sensor 500. When the first sensor 300 is in the first position, light emitted from the first lens assembly 200 is directly projected onto the first sensor 300 to form an image. At this time, the second lens assembly 400 is located behind the first sensor 300 and is in an idle state, not participating in image formation. When the first sensor 300 is in the second position, the first sensor 300 is rotated open by the rotating assembly 600, completely clearing the light path. At this time, the light emitted from the first lens assembly 200 no longer directly reaches the second sensor 500, but first passes through the second lens assembly 400. After the light is refracted, focused, and optimized again by the second lens assembly 400, it is finally projected onto the second sensor 500 behind it to form an image.

[0054] Traditional mobile phones, limited by internal space, typically feature multiple independent fixed-focus cameras (such as ultra-wide-angle, main camera, 3x telephoto, and 5x telephoto). Gaps between these lenses are filled with digital zoom, resulting in image quality degradation. While dual periscope solutions can achieve high-magnification zoom, they are bulky. This embodiment, without increasing the number of periscope prisms, achieves optical zoom for two different focal lengths on the same optical path by adding only a relatively small second lens assembly 400. For example, high-quality 3x mid-range and 10x telephoto lenses can be seamlessly integrated into a single module, significantly improving space utilization.

[0055] In one optional implementation, combined with Figure 3 and Figure 4 As shown, the camera module also includes a driving component 700, which is connected to the second sensor 500 and is used to drive the second sensor 500 to move along the optical path.

[0056] In this embodiment, the driving component 700 can be a voice coil motor or a non-motor, etc., to drive the second sensor 500 to move precisely back and forth along the optical axis. This is similar to the principle of focusing or zooming in a traditional camera by moving the lens assembly. Continuous optical zoom can also be achieved by moving the position of the second sensor 500.

[0057] In one optional implementation, combined with Figure 3 and Figure 4 As shown, the housing 100 is provided with a lead screw guide rail 130 along the optical path direction, and the second sensor 500 is slidably disposed on the lead screw guide rail 130.

[0058] The lead screw guide 130 is a rod-shaped component with precision threads, fixedly mounted inside the housing 100 along the optical path direction of the camera module (i.e., the direction in which the second sensor 500 needs to move). It provides stable support and guidance for the movement of the second sensor 500, ensuring that it does not deflect, tilt, or wobble during movement. The second sensor 500 can be connected to the lead screw guide 130 via a nut or slider. The nut or slider has a threaded hole that matches the thread of the lead screw guide 130. This improves the positioning accuracy and stability of the second sensor 500, preventing it from shaking or shifting, and ensuring the imaging performance of the camera module.

[0059] In an optional implementation, the first lens assembly 200 and the second lens assembly 400 can be moved along the optical path direction to achieve zoom, which will not be described in detail in this embodiment.

[0060] In one optional implementation, combined with Figure 1 and Figure 2 As shown, a light guide 800 is also provided in front of the first lens assembly 200. The light guide 800 is used to guide ambient light from outside the housing 100 into the first lens assembly 200. In an optional embodiment, the light guide 800 is a reflecting prism or a refractive prism.

[0061] In this embodiment, the light guide 800 is located at the entrance of the entire camera module's optical path. For example, it can be a right-angle prism. Ambient light first illuminates the light guide 800, and then enters the first lens assembly 200 after being reflected or refracted by the light guide 800. The first lens assembly 200 and the second lens assembly 400 share a single light guide 800, which simplifies the overall structure of the camera module, reduces the number of parts, thereby reducing the overall volume occupied, and also lowers the difficulty of manufacturing and assembly.

[0062] In one optional implementation, combined with Figure 1 and Figure 2 As shown, the housing 100 is provided with a light-transmitting hole 120, which is provided corresponding to the light guide 800 to guide ambient light from outside the housing 100 to the light-incident surface of the light guide 800. The aperture, shape, and position of the light-transmitting hole 120 can be designed as needed, and this embodiment does not impose specific limitations on them.

[0063] In one optional embodiment, the first lens assembly 200 is a 3x optical zoom lens; in another optional embodiment, the second lens assembly 400 is a 5x optical zoom lens.

[0064] In this embodiment, two sensors are mounted in the front and rear spaces of the camera module's optical path. The first lens assembly 200 in front is a large-size + 3X periscope, while the second lens assembly 400 in the rear is a small-size + 5X periscope, thereby increasing the applicability of the camera module.

[0065] Understandably, the size and focal length of the first lens assembly 200 and the second lens can be designed to other values ​​according to actual needs.

[0066] The camera module provided in this application embodiment includes a housing 100, a first lens assembly 200, a first sensor 300, and a second sensor 500. The housing 100 forms a receiving space 110 for the passage of light. The first lens assembly 200 and the second sensor 500 are arranged sequentially along the light path direction of the housing 100. The first sensor 300 is movably disposed in the housing 100, and the housing 100 is adapted to switch between a first position and a second position. In the first position, the first sensor 300 is located between the first lens assembly 200 and the second sensor 500, and the first sensor 300 is located in the light emission direction of the first lens assembly 200. In the second position, the first sensor 300 is located outside the light emission direction of the first lens assembly 200. By setting up two sensors and sharing a common optical path, and by moving the first sensor 300 to the light emission direction of the first lens assembly 200 so that the light is imaged on the first sensor 300; or by moving the first sensor 300 outside the light emission direction of the first lens assembly 200 so that the light is imaged on the second sensor 500, the overall volume of the camera module can be reduced while achieving zoom of the camera module.

[0067] Secondly, this application also provides an electronic device, which includes the camera module described in the above embodiments.

[0068] The electronic device may include, but is not limited to, mobile terminals, wearable devices, drones, in-vehicle devices, or security monitoring equipment.

[0069] It is understood that if the camera module has the beneficial effects of the above embodiments, then the electronic device will have the beneficial effects of the above embodiments accordingly.
