[0032] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0033] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0034] The camera module and electronic device provided in some embodiments of this disclosure are applied to scenarios that require photography using different focal lengths.

[0035] To meet users' shooting needs in different application scenarios, the camera modules of electronic devices need to cover multiple different focal lengths. In related technologies, electronic devices typically increase the number of camera modules to cover different focal lengths. For example, a vertical telephoto lens can be used to achieve a smaller zoom ratio, while a periscope can be used to achieve shooting at a longer focal length. However, this method of increasing the number of camera modules occupies a large amount of internal space in the electronic device.

[0036] In view of the above, some embodiments of this disclosure provide a camera module and an electronic device.

[0037] Figure 1 This is a schematic diagram of the structure of a camera module according to some embodiments of the present disclosure. Figure 2 This is an exploded view of a camera module according to some embodiments of the present disclosure. Figure 3 This is a schematic diagram of the operation of a first imaging system 11 according to some embodiments of the present disclosure. Figure 4 This is a schematic diagram of the range of motion of a first lens assembly 200 according to some embodiments of the present disclosure. Figure 5 This is a schematic diagram illustrating the operation of a second imaging system 12 according to some embodiments of the present disclosure. Figures 1 to 5 As shown, the camera module includes a carrier component 400, a light switching device 401, and an imaging system. The carrier component 400 has an incident light channel 13 and multiple beam-splitting channels 14 connected to the incident light channel 13. The light switching device 401 is disposed on the carrier component 400 and is used to guide the incident light entering the incident light channel 13 into at least one of the multiple beam-splitting channels 14, forming a corresponding optical path. The imaging system is disposed on the carrier component 400, and there are multiple imaging systems, each corresponding to one of the multiple beam-splitting channels 14. The imaging system performs imaging based on the optical path of its corresponding beam-splitting channel 14.

[0038] The light from the subject, i.e., the incident light, enters the camera module through the incident light channel 13, and is switched to a beam-splitting channel 14 by the light switching device 401, so that the incident light forms a corresponding optical path. Multiple beam-splitting channels 14 correspond to different optical paths, allowing the corresponding imaging devices to perform imaging using the corresponding optical paths. These different optical paths can meet the needs of various imaging systems for different focal lengths. Since the optical paths corresponding to each beam-splitting channel 14 share the incident light channel 13, integration of different imaging systems is achieved, saving space required for the optical paths of the camera module.

[0039] In some embodiments, such as Figures 2 to 5 As shown, the carrier assembly 400 includes a first cavity 420 and a second cavity 430 that are interconnected. The imaging system includes a first imaging system 11 and a second imaging system 12. A portion of the first cavity 420 forms an incident light channel 13, and another portion of the first cavity 420 forms a beam-splitting channel 14. The second cavity 430 forms another beam-splitting channel 14. The first cavity 420 is used to mount the first imaging system 11, and the second cavity 430 is used to mount the second imaging system 12.

[0040] The first imaging system 11 and the second imaging system 12 each perform imaging independently at different focal lengths. When the first imaging system 11 is operating, the light used for imaging enters through the first cavity 420. When the second imaging system 12 is operating, the light used for imaging, after passing through part of the first cavity 420, is reflected to the second cavity 430 by the light switching device 401, thus giving the light used for imaging by the second imaging system 12 a longer optical path to meet the focal length requirements of the second imaging system 12.

[0041] Figure 8 This is an exploded view of the carrier assembly 400 shown according to some embodiments of the present disclosure. Figure 9 This is a schematic diagram illustrating the structure of a light switching device 401 according to some embodiments of this disclosure. For example... Figure 5 , Figure 8 and Figure 9 As shown, in some embodiments, the light switching device 401 includes a reflector 4012 and a reflection driving device. The reflector 4012 is movably disposed inside the first cavity 420. The reflection driving device is connected to both the reflector 4012 and the carrier assembly 400, and is used to drive the reflector 4012 to a first position to avoid incident light, or to drive the reflector 4012 to a second position to reflect incident light into the second cavity 430. Figure 3 As shown, the reflection driving device drives the reflector 4012 to the first position. Figure 5 As shown, the reflection driving device drives the reflector 4012 to the second position. Thus, the switching of light is achieved by avoiding or reflecting light.

[0042] In some embodiments, the reflection driving device includes a connecting rod 4013 and a slider 4015. The opposite ends of the reflector 4012 are rotatably connected to the carrier assembly 400 and the connecting rod 4013, respectively. The connecting rod 4013 is rotatably connected to the slider 4015, and the slider 4015 is slidably connected to the carrier assembly 400. The slider 4015 is used to drive the reflector 4012 to rotate to a first position or a second position via the connecting rod 4013. The linkage-slider mechanism for driving the reflector 4012 is relatively simple in structure and reliable in operation.

[0043] The slider 4015 is slidably connected to the carrier assembly 400, and the linear motion of the slider 4015 is transformed into the curvilinear motion of the reflector 4012 through the linkage slider mechanism.

[0044] In some embodiments, the reflection driving device further includes a reflector carrier 4011. The reflector carrier 4011 has a frame structure, with the inner side of the frame structure used to fix the reflector 4012, and the outer side of the frame structure used to be movably connected to the slider 4015 and the carrier assembly 400, respectively.

[0045] In some embodiments, the reflective driving device further includes a shape memory alloy wire 4014 and a reset member 4016. The two ends of the shape memory alloy wire 4014 are connected to the carrier assembly 400 and the slider 4015, respectively, and the two ends of the reset member 4016 are also connected to the carrier assembly 400 and the slider 4015, respectively. The shape memory alloy wire 4014 and the reset member 4016 are used to drive the slider 4015 to reciprocate. The reset member 4016 is capable of elastic deformation. The shape memory alloy wire 4014 is made of shape memory alloy (SMA) and can deform when energized to drive the slider 4015.

[0046] For example, when the shape memory alloy wire 4014 is energized, it contracts, causing the slider 4015 to slide, which in turn causes the reflector 4012 to rotate from the first position to the second position. When the energization of the shape memory alloy wire 4014 is deactivated, the reset member 4016 pulls the slider 4015 back to its original position, which in turn causes the reflector 4012 to rotate from the second position to the first position.

[0047] In some embodiments, Figure 11 This is an exploded view of a first flexible circuit board 700 shown according to some embodiments of the present disclosure. Figure 11 As shown, the carrier assembly 400 is provided with a conductive spring 702. The conductive spring 702 is electrically connected to one end of the shape memory alloy wire 4014, and the conductive spring 702 is used to control the deformation of the shape memory alloy wire 4014 through an electrical signal. The shape memory alloy wire 4014 contracts when an electrical signal is applied, and extends and resets when the electrical signal is disconnected.

[0048] Figure 6 This is a schematic diagram of the structure of a first lens assembly 200 according to some embodiments of the present disclosure. Figure 7 This is an exploded view of a first lens assembly 200 shown according to some embodiments of the present disclosure. Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the first imaging system 11 includes a first lens assembly 200, a first photosensitive element 500, a first driving device, and a second driving device. The first lens assembly 200 is movably disposed in the first cavity 420, and the photosensitive side of the first photosensitive element 500 is opposite to the image side of the first lens assembly 200.

[0049] A first driving device is connected to both the carrier assembly 400 and the first lens assembly 200, and is used to drive the first lens assembly 200 to focus. A second driving device is connected to both the carrier assembly 400 and the first lens assembly 200, and is used to drive the first lens assembly 200 to stabilize its image.

[0050] like Figure 2 and Figure 8 As shown, a Cartesian coordinate system is established with the optical axis of the first lens assembly 200 as the z-axis and the optical axis of the second lens assembly 300 as the x-axis. When the first imaging system 11 is working, the incident light falls into the first photosensitive element 500 after passing through the first lens assembly 200. The carrier assembly 400 is provided with a first guide rail 403, and the first lens assembly 200 is slidably connected to the first guide rail 403, so that the first driving device can drive the first lens assembly 200 to move along the z-axis to achieve autofocus. The second driving device drives the first lens assembly 200 to move along the x-axis and y-axis directions to achieve image stabilization.

[0051] In some embodiments, the first driving device includes a first coil 703 and a first magnetic element 207. The first coil 703 is disposed on the inner wall of the first cavity 420, and there are multiple first coils 703 arranged along the optical axis of the first lens assembly 200. The first magnetic element 207 matches the first coil 703 and is disposed on the first lens assembly 200. By providing multiple first coils 703, the driving range of the first driving device on the first lens assembly 200 is increased, that is, the range of motion of the first lens assembly 200 within the first cavity 420 is increased. This, in turn, increases the focal length of the first imaging system 11 and provides space for the reflector 4012 to move.

[0052] In some embodiments, the second driving device includes multiple sets of second coils and second magnetic elements 203. The second coils are disposed on the inner wall of the first cavity 420, each first coil 703 corresponds to a set of second coils, and there are multiple sets of second coils arranged circumferentially along the optical axis of the first lens assembly 200. The second magnetic elements 203 are matched with the second coils and are disposed on the first lens assembly 200. By providing multiple second coils corresponding to the first coils 703, image stabilization can be achieved at any position of the first lens assembly 200 in the z-axis direction via the second driving device.

[0053] For example, such as Figure 7 As shown, the first lens assembly 200 includes a first lens 201, a lens carrier 202, a spring 204, a suspension wire 205, and a base 206. The first lens 201 is mounted on the lens carrier 202, and a second magnetic element 203 is mounted on the outer wall of the lens carrier 202, with its N and S poles arranged along the y-axis or x-axis. The lens carrier 202 is connected to the base 206 via the spring 204 and the suspension wire 205, allowing the lens carrier 202 to move relative to the base 206 along the y-axis and x-axis. A first magnetic element 207 is mounted on the outer wall of the base 206, with its N and S poles arranged along the z-axis. The base 206 is slidably connected to the carrier assembly 400 via a first guide rail 403.

[0054] Figure 10 This is a schematic diagram of the structure of a first flexible circuit board 700 according to some embodiments of the present disclosure. Figure 10 and Figure 11 As shown, the first imaging system 11 also includes a first flexible circuit board 700, which includes a first flexible circuit board body 701. The second coil includes an x-axis coil 707 and a y-axis coil 705, which are respectively matched with two second magnetic components 203 to drive the lens carrier 202 to move along the x-axis and y-axis directions for image stabilization. The first coil 703, x-axis coil 707, y-axis coil 705, and conductive spring 702 are integrated into the first flexible circuit board body 701, allowing the first flexible circuit board 700 to be directly mounted on the carrier assembly 400, thereby improving assembly efficiency.

[0055] The first flexible circuit board 701 also integrates a first Hall effect device 704, a second Hall effect device 706, and a third Hall effect device 708. The first Hall effect device 704 is positioned corresponding to the first coil 703 and is used to detect the position of the first lens 201 in the z-axis direction. The second Hall effect device 706 is positioned corresponding to the y-axis coil 705 and is used to detect the position of the first lens 201 in the y-axis direction. The third Hall effect device 708 is positioned corresponding to the x-axis coil 707 and is used to detect the position of the first lens 201 in the x-axis direction.

[0056] In some embodiments, the second imaging system 12 includes a second lens assembly 300, a second photosensitive element 600, and a third driving device. The second lens assembly 300 is movably disposed in the second cavity 430, and the photosensitive side of the second photosensitive element 600 is opposite to the image side of the second lens assembly 300. The third driving device is connected to both the carrier assembly 400 and the second lens assembly 300, and is used to drive the second lens assembly 300 to focus. The second imaging system 12 forms a periscope focusing structure through the light switching device 401, giving the second imaging system 12 a longer focal length.

[0057] In some embodiments, the reflector 4012 located at the second position is used to reflect light emitted from the image side of the first lens assembly 200 to the second lens assembly 300.

[0058] like Figure 5As shown, when the second imaging system 12 is working, light passes through the first lens assembly 200 and is reflected by the light switching device 401 to the second lens assembly 300. The light then passes through the second lens assembly 300 and falls into the second photosensitive element 600 to form an image. Since both the first lens assembly 200 and the second lens assembly 300 can be moved to focus, the second imaging system 12 can achieve continuous zoom. Furthermore, the light passing through the first lens assembly 200 and the second lens assembly 300 has a longer focal length, enabling a higher magnification zoom.

[0059] It should be noted that when the first imaging system 11 or the second imaging system 12 is working, the image stabilization function is implemented by the first lens assembly 200 and the second driving device.

[0060] Figure 12 This is a schematic diagram of the structure of a second flexible circuit board 800 according to some embodiments of the present disclosure. Figure 3 , Figure 8 and Figure 12 As shown, the third driving device includes a third coil 802 and a third magnetic component, which drive the second lens assembly 300 to move along the x-axis. The second imaging system 12 also includes a metal sheet 405. The carrier assembly 400 is provided with a second guide rail 404, and the metal sheet 405 and the second guide rail 404 are located on the same side of the second lens assembly 300. The second lens assembly 300 slides on the second cavity 430 via the second guide rail 404. The metal sheet 405 is fixed to the inner wall of the second cavity 430. By attracting the third magnetic component, the connection between the second lens assembly 300 and the second guide rail 404 is stabilized, thereby ensuring focusing stability. The second imaging system 12 also includes a second flexible circuit board 800, which includes a first flexible circuit board body 701. The third coil 802 is integrated into the second flexible circuit board body 801, allowing the second flexible circuit board 800 to be directly mounted on the carrier assembly 400, thereby improving assembly efficiency. The second flexible circuit board body 801 also integrates a fourth Hall effect device 803. The fourth Hall element 803 is set to correspond to the third coil 802 and is used to detect the position of the second lens assembly 300 in the x-axis direction.

[0061] In some embodiments, the carrier assembly 400 includes a carrier frame 402 and a housing 410. The carrier frame 402 serves to provide a mounting base, and the fastener attached to the carrier assembly 402 enhances protection.

[0062] According to some embodiments of this disclosure, an electronic device is provided, including the camera module described in any of the above embodiments. Light from the object being photographed, i.e., incident light, enters the camera module through the incident light channel 13, and is switched to a beam-splitting channel 14 by a light-switching device 401, thus forming a corresponding optical path. Multiple beam-splitting channels 14 correspond to different optical paths, enabling the corresponding imaging devices to perform imaging using the corresponding optical paths. The different optical paths can meet the requirements of various imaging systems for different focal lengths. The incident light channel 13 is shared among the optical paths corresponding to each beam-splitting channel 14, integrating different imaging systems, saving the space required for the optical path of the camera module, and thus saving internal space of the electronic device.

[0073] In the above detailed description, reference has been made to the accompanying drawings, which illustrate specific aspects of this disclosure by way of illustration. In this regard, terms indicating direction or positional relationship, such as “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” and “circumferential,” are used with reference to the orientation of the described figures. Since components of the described device can be positioned in multiple different orientations, directional terms are used for illustrative purposes and not for limitation. It should be understood that other aspects can be utilized and structural or logical changes can be made without departing from the concept of this disclosure. Therefore, the following detailed description should not be considered limiting.

[0074] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term "and / or" includes any of the associated listed items and any combination of any two or more; it should be understood that, unless otherwise expressly specified and limited, the terms "joining," "attaching," "mounting," "connecting," "linking," "fixing," etc., used in the embodiments of this disclosure should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral part; as a mechanical connection, an electrical connection, or a communicative connection; as a direct connection or an indirect connection through an intermediate medium; as a connection within two elements or an interaction between two elements, unless otherwise expressly limited. Those skilled in the art will understand the specific meaning of the above terms herein according to the specific circumstances.

[0075] Furthermore, the term "above" as used herein with respect to components, elements, or material layers formed or located "above" a surface may be used to indicate that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the term "above" as used with respect to components, elements, or material layers formed or located "above" a surface may also optionally have a specific meaning: that the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, for example, in direct contact with the surface.

[0076] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0077] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, a first component, part, region, layer, or section mentioned in the examples may also be referred to as a second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature.

[0078] It is further understood that the terms "first," "second," etc., are used to describe various types of information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another, and do not indicate a specific order or degree of importance. In fact, the expressions "first," "second," etc., are completely interchangeable. For example, without departing from the scope of this disclosure, first information can also be referred to as second information, and similarly, second information can also be referred to as first information.

[0079] In this description, "multiple" means at least two, referring to two or more, such as two, three, etc., unless otherwise explicitly specified. Other quantifiers are similar. The singular forms "a," "the," and "the" are also intended to include the plural forms unless the context clearly indicates otherwise. Furthermore, unless otherwise specified or clearly indicated from the context, the articles "a" and "an" as used in this application and the appended claims are generally understood to mean "one or more."

[0080] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term "and / or" includes any one of the related listed items and any combination of two or more; "and / or" describes the association relationship between related objects, indicating that three relationships may exist, for example, A and / or B can represent: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. Similarly, "at least one of..." includes any one of the related listed items and any combination of two or more.

[0081] Furthermore, the term "exemplary" is used herein to indicate that it serves as an example, instance, or illustration. Any aspect or design described herein as "exemplary" is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term "exemplary" is intended to present concepts in a concrete manner. As used herein, the term "or" is intended to indicate an inclusive "or" rather than an exclusive "or." That is, unless otherwise specified or clear from the context, "X applies A or B" is intended to indicate any of the natural inclusive permutations. That is, if X applies A; X applies B; or X applies both A and B, then applying A or B satisfies the condition under any of the foregoing instances.

[0082] Similarly, although this disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding the specification and drawings. This disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, the terminology used to describe such components is intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if it is not structurally equivalent to the disclosed structure. Furthermore, although specific features of this disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations, as may be desired and advantageous to any given or particular application. Moreover, with regard to the terms “comprising,” “owning,” “having,” “having,” or variations thereof as used in this disclosure, such terms are intended to be inclusive in a manner similar to the term “including.”

[0083] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the utility model disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.

[0084] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
