[0002] This application claims priority to Chinese Patent Application No. 202411555281.7, filed in China on November 4, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of electronic technology, specifically relating to a camera module and an electronic device. Background Technology

[0004] Camera functionality is an indispensable feature of smartphones and other electronic devices, providing essential applications in daily life such as taking photos, recording videos, video calls, payments, and entertainment. In recent years, some smart device manufacturers have introduced periscope telephoto cameras, capable of clearly capturing the detailed features of distant objects, bringing users a truly amazing and practical shooting experience.

[0005] However, due to limitations in electronic device space and investment costs, further improving telephoto performance faces significant challenges. One feasible solution is to add multiple periscope cameras to cover different telephoto focal lengths, thereby enhancing shooting results. However, this solution, which involves stacking multiple telephoto cameras, results in a large overall size, occupies a large area, and significantly increases costs. Summary of the Invention

[0006] The purpose of this application is to provide a camera module and electronic device that can solve the problem that existing electronic devices use multiple telephoto cameras stacked together, resulting in a large overall size, large board area, and significantly increased cost. This helps to reduce volume, improve board utilization, and save costs.

[0007] In a first aspect, embodiments of this application propose a camera module, comprising:

[0008] The housing comprises a photosensitive component, a main camera lens assembly, a first reflector driving assembly, a telephoto lens, and a second reflector, all disposed within the housing; wherein the first reflector driving assembly is located between the main camera lens assembly and the telephoto lens.

[0009] The main camera lens assembly is mounted on the photosensitive assembly;

[0010] The first reflector driving assembly includes a first reflector and a first driving structure. The first driving structure is used to drive the bottom of the main camera lens assembly away from the photosensitive assembly and drive the first reflector to move between the photosensitive assembly and the main camera lens assembly.

[0011] The second reflector is located below the telephoto lens and is used to reflect light incident from the telephoto lens; the first reflector is used to reflect the light reflected from the second reflector to the photosensitive component.

[0012] Secondly, embodiments of this application provide an electronic device, including:

[0013] case;

[0014] A camera module, wherein the camera module is the camera module according to the first aspect.

[0015] In an embodiment of this application, the camera module includes: a housing, a photosensitive component disposed within the housing, a main camera lens assembly, a first reflector driving assembly, a telephoto lens, and a second reflector; wherein, the first reflector driving assembly is located between the main camera lens assembly and the telephoto lens; the main camera lens assembly is disposed above the photosensitive component; the first reflector driving assembly includes a first reflector and a first driving structure, the first driving structure being used to drive the bottom of the main camera lens assembly away from the photosensitive component, and to drive the first reflector to move between the photosensitive component and the main camera lens assembly; the second reflector is located below the telephoto lens, and the second reflector is used to reflect light incident from the telephoto lens; the first reflector is used to reflect light reflected from the second reflector back to the photosensitive component.

[0016] In this way, by cleverly integrating the main camera lens, image sensor, and telephoto lens into a single module, multiple lenses share a single image sensor chip. Furthermore, the mirror drive assembly enables synchronized switching between different lenses. Specifically, when the main camera lens assembly is needed, the first mirror drive assembly defaults to its initial state where the first mirror is not being driven towards the main camera lens assembly. The bottom of the main camera lens assembly is initially positioned in contact with the image sensor, allowing light incident from the main camera lens assembly to enter the image sensor perpendicularly, thus enabling the main camera lens shooting function. When switching to the telephoto lens, the first mirror drive assembly drives the first mirror to move closer to the main camera lens assembly, moves the bottom of the main camera lens assembly away from the image sensor, and moves the first mirror between the image sensor and the main camera lens assembly. This allows light incident from the telephoto lens to be reflected by the second mirror back to the first mirror, and then by the first mirror back to the image sensor, enabling the telephoto lens shooting function. As can be seen, this solution can effectively switch between different camera lenses, and compared with the existing technology that uses multiple telephoto cameras stacked together, it can greatly reduce the overall size of the camera module, reduce the board area, and significantly reduce the equipment manufacturing cost.

[0035] To make the embodiments of this application clearer, the relevant technical background involved in the embodiments of this application, as well as the purpose and improvement points of this application, will be briefly introduced below:

[0036] Today, smartphones are an indispensable part of people's daily lives. In addition to basic communication functions, another important reason is that smartphone cameras provide people with important applications that are inseparable from daily life, such as taking photos, recording videos, video calls, making payments, and entertainment.

[0037] In recent years, the performance improvements of telephoto cameras have provided consumers with a stunning and practical shooting experience. Telephoto lenses can capture landscapes, text, portraits, and animals, while telephoto macro lenses can capture flowers, insects, documents, and objects. The multi-scenario applications and shooting effects of telephoto lenses have brought consumers a pleasant experience. As shown in Figure 1, some mobile phones are equipped with multiple cameras, such as a rear main camera 11, a periscope camera 12, a wide-angle camera 13, a front camera 14, and a portrait camera 15, which greatly improves the shooting performance of mobile phones. The cross-sectional diagrams of common telephoto cameras and rear main cameras in mobile phones are shown in Figure 2. The telephoto camera includes an IR component 21, a photosensitive chip 22, a substrate 23, a lens group 24, and a reflector 25, etc., while the rear main camera includes an IR component 26, a photosensitive chip 27, and a lens 28, etc.

[0038] There is still significant room for improvement in telephoto cameras. However, due to limitations imposed by phone thickness, cost, telephoto lens size, and optical performance, further enhancing telephoto performance presents considerable challenges. One solution to improve telephoto performance is to add multiple periscope cameras covering different telephoto focal lengths, thereby further improving image quality. As shown in Figure 3, with a conventional solution where the main camera is cropped to 2x and paired with a 3.5x periscope camera, the estimated diffraction-limited resolution (usually measured in TV lines) can reach 1100 line pairs up to 10x, but the shooting effect becomes less than ideal beyond 10x. As shown in Figure 4, when paired with two periscope cameras—a 4x telephoto and a 7x super-telephoto—the estimated diffraction-limited resolution at 14x is still quite good, still achieving over 1100 line pairs.

[0039] Therefore, it is clear that the idea of ​​using multiple telephoto lenses to improve overall photography performance is correct. However, simply stacking multiple telephoto lenses is by no means the best solution, as its disadvantages are also obvious, mainly as follows:

[0040] Firstly, the overall size is very large. Since each periscope telephoto lens is quite large, stacking multiple telephoto lenses will result in a very large overall size, taking up a large area of ​​the board and sacrificing battery capacity.

[0041] Secondly, due to size limitations, and because each individual telephoto camera cannot be designed to be large and optimal, the overall effect of stacking multiple telephoto lenses is not ideal.

[0042] Third, the cost increases significantly because each periscope camera is not cheap;

[0043] Fourth, the overall layout and appearance of the machine also face great challenges, making it difficult to achieve the best results.

[0044] To address this, this application designs a highly integrated, significantly smaller, and lower-cost single-chip multi-camera module with excellent image quality. Due to the large chip size, each camera can function as a main camera, hence the name "single-chip multi-main-camera module." The core idea of ​​this application is to cleverly integrate the core components of the rear main camera, telephoto periscope camera, or even a super-telephoto periscope camera, and even more cameras into a single unit, sharing a single sensor shift component. Through the coordinated switching of the motors and optical components of two or three cameras, rear main, telephoto, and super-telephoto shooting can be achieved according to the user's shooting commands.

[0045] The camera module provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0046] The basic principle and main structure of this application are as follows: the integrated design of three cameras—the rear main camera, the telephoto periscope camera, and even the ultra-telephoto periscope camera—is within a single camera body. They are not simply a stacking of multiple cameras, but rather a comprehensive and ingenious design of the core structure of multiple cameras.

[0047] Please refer to Figures 5 and 6, which are a cross-sectional view and a side view of the camera module provided in the embodiments of this application, respectively. As shown in Figures 5 and 6, the camera module includes:

[0048] The housing 800 includes a photosensitive component 100 disposed within the housing 800, a main camera lens assembly 200, a first reflector driving assembly 300, a telephoto lens 400, and a second reflector 601; wherein the first reflector driving assembly 300 is located between the main camera lens assembly 200 and the telephoto lens 400.

[0049] The main camera lens assembly 200 is mounted on the image sensor 100;

[0050] The first reflector driving assembly 300 includes a first reflector 301 and a first driving structure 303. The first driving structure 303 is used to move the bottom of the main camera lens assembly 200 away from the photosensitive assembly 100 and drive the first reflector 301 to move between the photosensitive assembly 100 and the main camera lens assembly 200.

[0051] The second reflector 601 is located below the telephoto lens 400 and is used to reflect light incident from the telephoto lens 400; the first reflector 301 is used to reflect the light reflected from the second reflector 601 to the photosensitive component 100.

[0052] As shown in Figures 5 and 6, the outermost part of the camera module is a protective housing 800, which is used to protect the internal module structure. First, a photosensitive component 100 is designed at one end inside the protective housing 800. This photosensitive component can also be called a sensor shift and infrared (IR) component, which consists of a substrate, a base, a sensor shift, an IR filter, a photosensitive chip, etc.

[0053] In some embodiments, the photosensitive component 100 includes a photosensitive chip 101, a substrate 102, a base, and an IR component 103;

[0054] The photosensitive chip 101 is disposed in a spatial structure consisting of a substrate 102, a base, and an IR component 103.

[0055] Specifically, the substrate 102 can be located at the bottom, closely attached to the bottom of the housing 800. The base and IR component 103 are disposed on the substrate 102, and the substrate 102, the base, and the IR component 103 form a spatial structure. The photosensitive chip 101 (shown by the red dashed box in Figures 5 and 6) is disposed in this spatial structure. The substrate 102, the base, and the IR component 103 provide electrical and optical signal transmission and jointly protect the photosensitive chip 101 to ensure normal operation within it. In this way, the photosensitive component 100 can have a relatively reliable structure, and the photosensitive chip 101 can also be better protected.

[0056] Secondly, a main camera lens assembly 200, also called a main camera motor lens assembly, can be designed directly above the photosensitive assembly 100. By default, the photosensitive assembly 100 and the main camera lens assembly 200 constitute the main camera imaging function module, that is, the camera module uses the main camera imaging function by default.

[0057] Next, adjacent to the photosensitive component 100 and the main camera lens assembly 200, a first reflector drive assembly 300 is designed, namely the reflector 1 and its drive assembly, which consists of a first reflector 301, a first drive structure 303, etc. The first reflector 301 can also be called reflector 1. The first drive structure 303 can provide a horizontal driving force to the first reflector 301, driving the first reflector 301 to translate horizontally. At the same time, the first drive structure 303 can also push the bottom of the main camera lens assembly 200 away from the photosensitive component 100, such as driving the first side of the main camera lens assembly 200 to rotate relative to the connection of the housing 800, causing the second side of the main camera lens assembly 200 to rise away from the photosensitive component 100 or fall towards the photosensitive component 100. The first reflector 301 then moves to the angled space formed between the photosensitive component 100 and the main camera lens assembly 200, or exits from the angled space.

[0058] On the other side of the first reflector driving assembly 300 away from the main camera lens assembly 200, a telephoto lens 400 is designed to realize the telephoto shooting function. The focal length of the telephoto lens 400 is related to its distance from the photosensitive assembly 100. In other words, the distance between the telephoto lens 400 and the photosensitive assembly 100 can be reasonably arranged according to the required telephoto focal length.

[0059] The second reflector 601 can be fixedly positioned below the telephoto lens 400, or its position can be changed by a driving structure. For example, when there is only one telephoto lens 400, the second reflector 601 can be directly fixedly positioned below the telephoto lens 400. When there is more than one telephoto lens 400, such as a super telephoto lens or a lens with other focal lengths, a corresponding second reflector driving structure can be added to drive the second reflector 601 to switch its position on the lens according to the user's shooting instructions. For example, when it is necessary to use the telephoto lens 400 for shooting, the second reflector 601 can be driven to move to the position directly below the telephoto lens 400.

[0060] The second reflector 601 has a reflective surface for reflecting light incident from the telephoto lens 400, as shown in the incident light diagrams in Figures 9 and 10; the first reflector 301 also has a reflective surface for reflecting light reflected from the second reflector 601 into the photosensitive chip 101 in the photosensitive assembly 100.

[0061] In a specific application, when using the main camera lens assembly 200 to take a picture, the bottom of the main camera lens assembly 200 is attached to the upper surface of the photosensitive assembly 100 to form the main camera image, so that the light incident from the main camera lens assembly 200 enters the photosensitive assembly 100 perpendicularly.

[0062] When shooting with the telephoto lens 400, the second reflector 601 is located below the telephoto lens 400. The first driving structure 303 drives the first reflector 301 to move closer to the main camera lens assembly 200, and pushes the bottom of the main camera lens assembly 200 away from the photosensitive assembly 100, until the first reflector 301 moves into the space between the photosensitive assembly 100 and the main camera lens assembly 200, and the reflective surface of the first reflector 301 is opposite to the bottom surface of the main camera lens assembly 200; wherein, the light incident from the telephoto lens 400 is reflected by the reflective surface of the second reflector 601 to the reflective surface of the first reflector 301, and finally reflected by the reflective surface of the first reflector 301 to the photosensitive assembly 100;

[0063] In other words, when using the main camera for initial shooting, as shown in Figures 5 to 7, the first reflector driving component 300 can be in the initial state where the first reflector 301 is not driven to move towards the main camera lens component 200. The bottom of the main camera lens component 200 is in the initial position where it is attached to the photosensitive component 100, so that the light incident from the main camera lens component 200 enters the photosensitive component 100 perpendicularly, thereby realizing the main camera lens shooting function.

[0064] When it is necessary to switch to using the telephoto camera for shooting, as shown in Figures 9 and 10, the second reflector 601 can be positioned directly below the telephoto lens 400. As shown in Figure 8, the first reflector driving component 300 drives the first reflector 301 to move closer to the main camera lens component 200, and pushes the bottom of the main camera lens component 200 away from the photosensitive component 100. As shown in Figures 9 and 10, the first reflector 301 eventually moves between the photosensitive component 100 and the main camera lens component 200, so that the light incident from the telephoto lens 400 can be reflected by the reflective surface of the second reflector 601 to the reflective surface of the first reflector 301, and then reflected by the reflective surface of the first reflector 301 to the photosensitive component 100, thus realizing the telephoto lens shooting function.

[0065] When it is necessary to switch back to using the main camera for shooting, as shown in Figure 8, the first reflector driving component 300 can drive the first reflector 301 to move away from the main camera lens component 200 and pull the bottom of the main camera lens component 200 to move closer to the photosensitive component 100, as shown in Figures 6 and 7. The first reflector 301 then moves out from between the photosensitive component 100 and the main camera lens component 200 until the bottom of the main camera lens component 200 returns to the position of being in contact with the photosensitive component 100, so that the light incident from the main camera lens component 200 enters the photosensitive component 100 perpendicularly, realizing the main camera shooting function.

[0066] Optionally, the first side of the main camera lens assembly 200 facing away from the first reflector drive assembly 300 is rotatably connected to the housing 800; the second side of the main camera lens assembly 200 is rotatably connected to the first reflector drive assembly 300, and the second side is opposite to the first side;

[0067] The first driving structure 303 is used to drive the first reflector 301 to move in the horizontal direction, and when driving the first reflector 301 to move closer to the main camera lens assembly 200, it pushes the second side of the main camera lens assembly 200 to rise away from the photosensitive assembly 100, so that the first reflector 301 moves between the photosensitive assembly 100 and the main camera lens assembly 200.

[0068] In some embodiments, the first side of the main camera lens assembly 200 facing away from the first reflector drive assembly 300 (as shown on the right side in Figure 5) can be rotatably connected to the corresponding position of the housing 800. Specifically, this can be achieved through a structure such as a pivot or hinge, which rotatably connects or hinges the main camera lens assembly 200 to a fixed connector at the corresponding position of the housing 800. The second side of the main camera lens assembly 200 facing the first reflector drive assembly 300 can then be rotatably connected to the first reflector drive assembly 300. In this way, the first side of the main camera lens assembly 200 can be driven to rotate relative to the housing 800 by the first reflector drive assembly 300, causing the second side of the main camera lens assembly 200 to rise away from the photosensitive assembly 100 or fall towards the photosensitive assembly 100.

[0069] In this embodiment, when it is necessary to switch to using the telephoto camera for shooting, as shown in Figures 9 and 10, the second reflector 601 can be positioned directly below the telephoto lens 400. As shown in Figure 8, the first reflector driving component 300 drives the first reflector 301 to move closer to the main camera lens component 200 and pushes the first side of the main camera lens component 200 to rotate relative to the housing 800, causing the second side of the main camera lens component 200 to rise away from the photosensitive component 100. As shown in Figures 9 and 10, the first reflector 301 eventually moves between the photosensitive component 100 and the main camera lens component 200, so that the light incident from the telephoto lens 400 can be reflected by the reflective surface of the second reflector 601 to the reflective surface of the first reflector 301, and then reflected by the reflective surface of the first reflector 301 to the photosensitive component 100, thus realizing the telephoto lens shooting function.

[0070] When it is necessary to switch back to using the main camera for shooting, as shown in Figure 8, the first reflector driving component 300 can drive the first reflector 301 to move away from the main camera lens component 200, and pull the first side of the main camera lens component 200 to rotate relative to the housing 800, so that the second side of the main camera lens component 200 falls back towards the photosensitive component 100, as shown in Figures 6 and 7. The first reflector 301 then moves out from between the photosensitive component 100 and the main camera lens component 200 until the bottom of the main camera lens component 200 returns to the position of being in contact with the photosensitive component 100, so that the light incident from the main camera lens component 200 enters the photosensitive component 100 vertically, realizing the main camera shooting function.

[0071] This implementation method can effectively drive the main camera lens assembly 200 to move relative to the photosensitive assembly 100, thereby achieving a state switch between the two aligning or forming an oblique space.

[0072] Optionally, the first reflector drive assembly 300 further includes a first base 302 and a connecting rod 304. The first reflector 301 is fixedly mounted on the first base 302, and the two ends of the connecting rod 304 are rotatably connected to the first drive structure 303 and the second side of the main camera lens assembly 200, respectively.

[0073] The first drive structure 303 is used to drive the first base 302 to move in the horizontal direction. When the first base 302 is driven to move closer to the main camera lens assembly 200, the drive link 304 pushes the second side of the main camera lens assembly 200 to rise away from the photosensitive assembly 100, so that the first reflector 301 moves between the photosensitive assembly 100 and the main camera lens assembly 200.

[0074] In some embodiments, the first reflector driving assembly 300 may include a first base 302 and a connecting rod 304. The first reflector 301 may be fixedly mounted on the first base 302. The first driving structure 303 drives the first reflector 301 to move by driving the first base 302. Correspondingly, a track may be provided below the first base 302. The first driving structure 303 is also connected to the main camera lens assembly 200 by the connecting rod 304. Specifically, the two ends of the connecting rod 304 are respectively connected to the second side of the first driving structure 303 and the main camera lens assembly 200, and are connected in a movable manner, that is, the two ends of the connecting rod 304 can rotate relative to the first driving structure 303 and the main camera lens assembly 200, respectively.

[0075] The first drive structure 303 can provide a horizontal driving force to the first base 302, driving the first base 302 to translate horizontally, thereby driving the first reflector 301 to move. At the same time, the first drive structure 303 can also push the connecting rod 304 to rotate around the connecting fulcrum, thereby pushing the first side of the main camera lens assembly 200 to rotate relative to the connection point of the housing 800, causing the second side of the main camera lens assembly 200 to rise away from the photosensitive assembly 100 or fall towards the photosensitive assembly 100. The first reflector 301 then moves to the angled space formed between the photosensitive assembly 100 and the main camera lens assembly 200, or exits from the angled space.

[0076] In a specific application, when using the telephoto lens 400 for shooting, the second reflector 601 is located directly below the telephoto lens 400. The first drive structure 303 drives the first base 302 to move closer to the main camera lens assembly 200 and pushes the connecting rod 304 to move, thereby pushing the main camera lens assembly 200 to rotate relative to the housing 800. This causes the second side of the main camera lens assembly 200 to rise away from the photosensitive component 100 until the first reflector 301 moves to the oblique space between the photosensitive component 100 and the main camera lens assembly 200. This allows light incident from the telephoto lens 400 to be reflected to the photosensitive component 100 through the second reflector 601 and the first reflector 301, thus realizing the telephoto lens shooting function.

[0077] When only the main camera is used for shooting and the telephoto lens 400 is not needed, as shown in Figure 8, the first reflector drive assembly 300 can drive the first base 302 to move the first reflector 301 away from the main camera lens assembly 200, and pull the connecting rod 304 to move, thereby pulling the main camera lens assembly 200 to rotate relative to the housing 800, so that the second side of the main camera lens assembly 200 falls back towards the photosensitive assembly 100, as shown in Figures 6 and 7. The first reflector 301 then moves out from between the photosensitive assembly 100 and the main camera lens assembly 200 until the bottom of the main camera lens assembly 200 returns to the position of being in contact with the photosensitive assembly 100, so that the light incident from the main camera lens assembly 200 enters the photosensitive assembly 100 vertically, realizing the main camera shooting function.

[0078] This implementation method effectively drives the first reflector and the main camera lens assembly 200, enabling flexible switching between shooting with the main camera lens and the telephoto lens.

[0079] Optionally, in some embodiments, the main camera lens assembly 200 includes a main camera lens 201, a main camera pivot 202, and a connecting rod 203;

[0080] The main camera pivot 202 is located on the first side, and the main camera lens 201 is rotatably connected to the connector on the housing 800 through the main camera pivot 202.

[0081] The connecting rod connector 203 is disposed on the second side and is rotatably connected to one end of the connecting rod 304.

[0082] As shown in Figures 5 and 6, the main camera lens assembly 200 includes a main camera lens 201, a main camera pivot 202 located on the outer side, and a connecting rod connector 203 for connecting the connecting rod 304. The connecting rod connector 203 can also be called a main camera rotatable hinge. That is, one end of the connecting rod 304 can be hinged to the main camera lens assembly 200 through the connecting rod connector 203, and the main camera lens assembly 200 can also be rotatably connected to the corresponding connector on the housing 800 through the main camera pivot 202. In this way, one side of the main camera lens assembly 200 can rotate relative to the housing 800 through the pivot, while the other side can be movably connected to the connecting rod 304, so that it can be pushed or pulled by the connecting rod 304 to move away from or towards the photosensitive component 100.

[0083] According to some embodiments of the present application, as shown in FIG5 and FIG6, the camera module further includes an ultra-telephoto lens 500 disposed in the housing 800 and a second reflector driving assembly 600, the second reflector driving assembly 600 including a second reflector 601, a second base 602 and a second driving structure 603.

[0084] The telephoto lens 400 is located between the first reflector drive assembly 300 and the super telephoto lens 500; the second reflector 601 is fixedly mounted on the second base 602, and the second drive structure 603 can drive the second base 602 to move in the horizontal direction.

[0085] In some embodiments, a telephoto lens 400, a super telephoto lens 500, and a second telephoto lens 600 may also be designed on the other side of the first reflector driving assembly 300 that is away from the main camera lens assembly 200. Specifically, since the super telephoto lens 500 has a longer focal length, it is positioned further away from the main camera lens assembly 200.

[0086] It should be understood that a telephoto lens refers to a lens with a focal length of 200 mm or more, and it is further divided into telephoto and super telephoto lenses. Telephoto lenses have a focal length between 200 and 300 mm, suitable for shooting close-ups of distant people or animals, as well as stage performances and fashion shows. Super telephoto lenses have a focal length of 400 mm or more, often used to capture images of birds that are difficult to approach, dangerous wild animals, and to photograph competitions in large stadiums, astronomical subjects, etc., easily capturing the target from a distance. Each focal length range of a telephoto lens has its corresponding most suitable subject. Therefore, in this application embodiment, the telephoto lens 400 can refer to a telephoto lens with a focal length between 200 and 300 mm, and the super telephoto lens 500 can refer to a telephoto lens with a focal length of 400 mm or more.

[0087] The second reflector drive assembly 600, also called reflector 2 and its drive assembly, includes a second reflector 601, a second base 602 and a second drive structure 603. The second reflector 601, also called reflector 2, is fixedly installed on the second base 602, and a track can be provided below the second base 602.

[0088] The second drive structure 603 can provide a horizontal driving force to the second base 602, driving the second base 602 to move horizontally and translate, thereby driving the second reflector 601 to move to the position directly below the telephoto lens 400 or the super telephoto lens 500, realizing the switching between the telephoto lens 400 and the super telephoto lens 500.

[0089] When a user needs to select different magnification levels for shooting, or switch from the main camera to telephoto or super telephoto shooting, the first reflector 301 and the main camera lens assembly 200 switch in tandem under the action of the drive mechanism.

[0090] Specifically, when using the telephoto lens 400 for shooting, the second drive structure 603 drives the second base 602 to move closer to the telephoto lens 400 until the second reflector 601 is located directly below the telephoto lens 400, as shown in Figures 9 and 10, thus realizing the telephoto shooting function.

[0091] When using the super telephoto lens 500 for shooting, the second drive structure 603 drives the second base 602 to move closer to the super telephoto lens 500 until the second reflector 601 is located directly below the super telephoto lens 500, as shown in Figures 11 and 12, thus realizing the super telephoto shooting function.

[0092] In both cases where shooting is performed using the super telephoto lens 500 or the telephoto lens 400, the first reflector 301 can be positioned between the photosensitive element 100 and the main camera lens assembly 200. That is, under the driving action of the first driving structure 303, the first reflector 301 can be moved to the position between the photosensitive element 100 and the main camera lens assembly 200.

[0093] This implementation method can integrate three camera functions—main camera, telephoto, and super telephoto—into a single camera module, and enable the coordinated switching of shooting functions between different camera lenses. While ensuring excellent shooting performance, it also ensures that the overall size of the camera module is not too large, saving space and reducing manufacturing costs.

[0094] According to a further embodiment of the present application, the second drive structure 603 is disposed between the telephoto lens 400 and the super telephoto lens 500.

[0095] In some embodiments, to ensure a rapid response and reduce waiting time when the second reflector 601 is driven in both lens directions, as shown in Figures 6 and 7, the second driving structure 603 can be positioned between the telephoto lens 400 and the super telephoto lens 500, such as in the middle position between the two. In this way, a rapid response can be achieved whether the second reflector 601 is driven to move downwards towards the telephoto lens 400 or downwards towards the super telephoto lens 500.

[0096] According to some embodiments of the present application, the first drive structure 303 includes a motor 31, a transmission wheel 32, a transmission shaft 33, and a transmission rack 34. The transmission rack 34 meshes with the transmission wheel 32 and is disposed on the side of the first base 302. The motor 31 and the transmission shaft 33 are both fixedly disposed on the housing 800. When the motor 31 drives the transmission wheel 32 to rotate around the transmission shaft 33, it drives the first base 302 to move in the horizontal direction.

[0097] As shown in Figures 6 and 7, the first drive structure 303 consists of a motor 31, a transmission wheel 32, a transmission shaft 33, and a transmission rack 34. The motor 31 is fixed to the protective housing 800, and the transmission wheel 32 is fixed to the protective housing 800 via the transmission shaft 33. The motor 31 drives the transmission wheel 32 to rotate. The transmission rack 34 on the first base 302 meshes with the transmission wheel 32. When the transmission wheel 32 rotates, it drives the first base 302 to translate, thereby moving the first reflector 301. In this way, the first base and the first reflector can be smoothly driven to move through gear meshing, thus enabling the switching between the main camera lens and the telephoto lens.

[0098] According to some embodiments of the present application, the second drive structure 603 includes a motor 61, a transmission wheel 62, a transmission shaft 63, and a transmission rack 64. The transmission rack 64 meshes with the transmission wheel 62 and is disposed on the side of the second base 602. The motor 61 and the transmission shaft 63 are both fixedly disposed on the housing 800. When the motor 61 drives the transmission wheel 62 to rotate around the transmission shaft 63, it drives the second base 602 to move in the horizontal direction.

[0099] As shown in Figures 6 and 7, the second drive structure 603 consists of a motor 61, a transmission wheel 62, a transmission shaft 63, and a transmission rack 64. The motor 61 is fixed to the protective housing 800, and the transmission wheel 62 is fixed to the protective housing 800 via the transmission wheel and transmission shaft 63. The motor 61 drives the transmission wheel 62 to rotate, and the transmission rack 64 on the second base 602 meshes with the transmission wheel 62. When the transmission wheel 62 rotates, it drives the second base 602 to translate, thereby driving the second reflector 601 to move.

[0100] Specifically, the motor 61 can drive the second base 602 and the second reflector 601 to move directly below the telephoto lens 400 or the super telephoto lens 500 according to the user's instructions, so as to perform telephoto or super telephoto shooting according to the user's needs. Figures 9 and 10 show telephoto imaging, and Figures 11 and 12 show super telephoto imaging.

[0101] In this way, the second base and the second reflector can be smoothly driven through gear meshing, thereby enabling the switching between telephoto and super telephoto lenses.

[0102] According to a further embodiment of the present application, one end of the connecting rod 304 is rotatably connected to the transmission wheel anchor point 35 on the transmission wheel 32, and the other end of the connecting rod 304 is hinged to the connecting rod connector 203 on the second side of the main camera lens assembly 200.

[0103] As shown in Figures 5 and 6, a drive wheel anchor point 35 is designed on the inner side of the outer diameter of the drive wheel 32 to fix one end of the connecting rod 304. The connecting rod 304 can rotate around the drive wheel anchor point 35. The other end of the connecting rod 304 is fixed to one corner of the motor of the main camera lens assembly 200 through the connecting rod connector 203, also called the main camera rotatable hinge. When the drive wheel 32 rotates under the drive of the motor 31, the connecting rod 304 also rotates with the drive wheel 32, thereby pushing the main camera lens assembly 200 to rotate and rise around the main camera rotation axis 202. When the main camera lens assembly 200 is raised, space is left so that the first reflecting mirror 301 can move above the photosensitive component 100.

[0104] This implementation method can effectively achieve linkage transmission, thereby driving the main camera lens assembly 200 to rise or fall.

[0105] According to some embodiments of the present application, the camera module further includes a focusing lens 700 disposed within the housing 800, located between the first reflector driving assembly 300 and the telephoto lens 400;

[0106] The 700 focusing lens is used in conjunction with the 400 telephoto lens or the 500 super telephoto lens to adjust the focal length for telephoto shooting.

[0107] As shown in Figures 5 and 6, in some embodiments, a focusing lens 700 can also be provided between the telephoto lens 400 and the first reflector driving assembly 300. This focusing lens 700 is used to adjust the focal length in conjunction with the telephoto lens 400 or the super telephoto lens 500. The focusing lens 700 can also be called a composite telephoto lens. In other words, the telephoto lens 400 and the super telephoto lens 500 need to work together with the focusing lens 700 to produce excellent images on the photosensitive chip 101. In specific implementation, the three lenses—the telephoto lens 400, the super telephoto lens 500, and the focusing lens 700—can all undergo professional and comprehensive optical design.

[0108] In this way, the 700-degree focusing lens can be used in conjunction with the 400-degree telephoto lens and the 500-degree super telephoto lens to produce excellent imaging and ensure the quality of the captured images.

[0109] Optionally, the telephoto lens 400 includes a group of telephoto lenses, and / or the super telephoto lens 500 includes a group of super telephoto lenses, and / or the focusing lens 700 includes a group of focusing lenses.

[0110] In some embodiments, in simple application scenarios, such as in automotive in-vehicle equipment, the telephoto lens 400, the super telephoto lens 500, and the focusing lens 700 can all be single lenses. Alternatively, depending on the shooting requirements of different scenarios, a single lens can be used for a certain function, while a lens group consisting of multiple lenses can be used for other functions.

[0111] In other embodiments, in some complex application scenarios with high requirements for shooting quality, such as in mobile phones, the telephoto lens 400, the super telephoto lens 500, and the focusing lens 700 can all adopt a lens group composed of multiple lenses. For example, the telephoto lens 400 adopts a telephoto lens group composed of multiple telephoto lenses, the super telephoto lens 500 adopts a super telephoto lens group composed of multiple super telephoto lenses, and the focusing lens 700 adopts a focusing lens group composed of multiple focusing lenses.

[0112] Optionally, the first reflector 301 and / or the second reflector 601 are triangular block structures, the first reflector 301 includes a first inclined surface, the second reflector 601 includes a second inclined surface, and the first inclined surface is parallel to the second inclined surface.

[0113] In some embodiments, as shown in Figures 5 to 12, both the first reflector 301 and the second reflector 601 can adopt a triangular block structure, specifically a right-angled triangular block. One side can serve as the bottom surface, parallel to the bottom surface of the housing 800, the other side is perpendicular to the bottom surface, and the inclined surface can serve as the reflecting surface. Furthermore, the inclined surface of the first reflector 301 (i.e., the first inclined surface) is parallel to the inclined surface of the second reflector 601 (i.e., the second inclined surface). For example, the first reflector 301 is an upright triangular block structure, and the second reflector 601 is an inverted triangular block structure, or in other words, the second reflector 601 is rotated 180 degrees relative to the first reflector 301.

[0114] Thus, as shown in the incident light in Figures 9 to 12, it can be ensured that the light rays incident from the telephoto lens 400 or the super telephoto lens 500 are reflected into horizontal light rays after reaching the second inclined surface of the second reflector 601, pass through the focusing lens 700 and reach the first inclined surface of the first reflector 301, where they are reflected into vertical light rays again, and finally enter the photosensitive chip 101, so as to achieve good light-sensing shooting through the telephoto lens or the super telephoto lens.

[0115] It should be noted that in some embodiments, the first reflector 301 and / or the second reflector 601 may also be simply a prism placed at an angle.

[0116] According to some embodiments of the present application, the main camera lens assembly 200, the telephoto lens 400, and the super telephoto lens 500 are manufactured as a single unit;

[0117] Alternatively, the main camera lens assembly 200, the telephoto lens 400, and the super telephoto lens 500 are manufactured in segments and assembled using an active focusing process;

[0118] Alternatively, the main camera lens assembly 200 and the telephoto lens 400 can be manufactured as a single unit, and then assembled with the segmented super telephoto lens 500 using an active focusing process.

[0119] The purpose of this application is to design a highly integrated module that uses a single chip for the main camera, telephoto lens, and super telephoto lens. This module is ultimately a single unit, and the manufacturing process can be determined based on design, production, and supply conditions. Alternatively, the main camera, telephoto lens, and super telephoto lens can be designed and manufactured as a single unit, or they can be manufactured separately and then assembled into a complete module using specific manufacturing processes, such as active alignment. If a separate manufacturing and reassembly approach is adopted, it is recommended that the main camera and telephoto lens be manufactured as a single unit, as their operation is closely interconnected, and then combined with the super telephoto lens.

[0120] It should be noted that regardless of which manufacturing method is used, it is necessary to comprehensively design each component and fully consider the most efficient and reliable cooperation and linkage between them.

[0121] The embodiments of this application can achieve the following significant beneficial effects:

[0122] 1) The photo quality is significantly improved. Compared with the single telephoto periscope camera that is the mainstream feature of current high-end flagship phones, this application adds telephoto and super telephoto designs to bring users a better shooting experience.

[0123] 2) The overall size of the camera is greatly reduced. This application is not a simple stacking of three cameras: main camera, telephoto and super telephoto. Instead, it is a comprehensive and ingenious design of the core motor and lens structure of the three cameras, so that the three cameras can switch in conjunction with each other and share a single chip. Compared with a single camera, the motor, lens, protective shell and other structures are shared significantly, and the area is estimated to be saved by 40% to 50%.

[0124] 3) The overall cost of the camera is significantly reduced. Since multiple lenses share a single image sensor, it saves on the large-sensor image sensors of other lenses, which account for a high percentage of the cost of the camera module. Saving on some motors, lenses, and drive components also has a significant impact on cost. For example, the telephoto lens 400 and the super telephoto lens 500 share a single drive structure, namely the second reflector drive component 600, and also share the focusing lens 700. Integrated design and manufacturing significantly reduce costs in R&D, production, fixtures, and logistics.

[0125] This application is not limited to mobile phone cameras, but can be applied to other electronic products and devices such as PCs, personal game consoles, and automobiles.

[0126] A camera module according to an embodiment of this application includes: a housing, a photosensitive component disposed within the housing, a main camera lens assembly, a first reflector driving assembly, a telephoto lens, and a second reflector; wherein, the first reflector driving assembly is located between the main camera lens assembly and the telephoto lens; the main camera lens assembly is disposed above the photosensitive component; the first reflector driving assembly includes a first reflector and a first driving structure, the first driving structure being used to drive the bottom of the main camera lens assembly away from the photosensitive component and to drive the first reflector to move between the photosensitive component and the main camera lens assembly; the second reflector is located below the telephoto lens, the second reflector being used to reflect light incident from the telephoto lens; the first reflector being used to reflect light reflected from the second reflector back to the photosensitive component.

[0127] In this way, by cleverly integrating the main camera lens, image sensor, and telephoto lens into a single module, multiple lenses share a single image sensor chip. Furthermore, the mirror drive assembly enables synchronized switching between different lenses. Specifically, when the main camera lens assembly is needed, the first mirror drive assembly defaults to its initial state where the first mirror is not being driven towards the main camera lens assembly. The bottom of the main camera lens assembly is initially in contact with the image sensor, allowing light incident from the main camera lens assembly to enter the image sensor perpendicularly, thus enabling the main camera lens shooting function. When switching to the telephoto lens, the first mirror drive assembly drives the first mirror to move closer to the main camera lens assembly, and drives the bottom of the main camera lens assembly away from the image sensor. The first mirror then moves to a position between the image sensor and the main camera lens assembly, allowing light incident from the telephoto lens to be reflected by a second mirror back to the first mirror, and then by the first mirror back to the image sensor, thus enabling the telephoto lens shooting function. As can be seen, this solution can effectively switch between different camera lenses, and compared with the existing technology that uses multiple telephoto cameras stacked together, it can greatly reduce the overall size of the camera module, reduce the board area, and significantly reduce the equipment manufacturing cost.
