[0022] The following is combined with Figures 1 to 22 This application describes a camera module 100 and a smart wearable device provided according to embodiments of the present application.

[0023] like Figures 1 to 15 As shown, according to a first aspect of this application, a camera module 100 is provided, including a camera module 1, a bracket assembly 2, and a control module 3; the camera module 1 includes a lens, a support base 11, a first magnetic component 12, and a second magnetic component 13, the lens being disposed at a first end of the support base 11, the first magnetic component 12 being disposed at a second end of the support base 11, and the second magnetic component 13 being disposed on the periphery of the support base 11; the bracket assembly 2 includes a fixing base 21, a third magnetic component 22, and a fourth magnetic component 23, the first end of the fixing base 21 being provided with a direction along a first direction (the X direction in the figures, typically the initial orientation of the camera module 1). The assembly slot 211 extends to the first direction. The third magnetic component 22 is disposed on the bottom wall of the assembly slot 211, and the fourth magnetic component 23 is disposed on the side wall of the assembly slot 211. The control module 3 is electrically connected to the camera module 1. The first magnetic component 12 and / or the second magnetic component 13, the third magnetic component 22 and / or the fourth magnetic component 23 are respectively electrically connected to the control module 3. The second end of the camera module 1 is assembled in the assembly slot 211. The control module 3 can control the polarity of the magnetic poles of at least some of the magnetic components to make the camera module 1 have a degree of freedom of movement along the first direction and a degree of freedom of rotation about the first direction relative to the bracket assembly 2.

[0024] Specifically, in this embodiment, the camera module 1 uses the support base 11 as its core carrier. A lens is fixed at its first end to achieve imaging, a first magnetic component 12 is provided at its second end, and a second magnetic component 13 is arranged around its periphery, forming magnetic action points at different locations. The bracket assembly 2 is based on the fixed base 21, with an assembly groove 211 extending along a first direction at its first end, providing assembly space for the camera module 1. A third magnetic component 22 is correspondingly provided on the bottom wall of the assembly groove 211, and a fourth magnetic component 23 is correspondingly provided on the side wall, forming a corresponding alignment with the first magnetic component 12 and the second magnetic component 13 on the camera module 1. During assembly, the second end of the camera module 1 is directly embedded into the assembly groove 211 of the bracket assembly 2 for initial positioning. The control module 3 is electrically connected to the camera module 1 and also electrically connected to at least some of the first, second, third, and fourth magnetic components 23, providing an electrical foundation for subsequent control of the working state of the camera module 1 and the magnetic control of the camera module 1 and the bracket assembly 2. The overall assembly structure is compact, and the division of labor among the components is clear, laying a structural foundation for realizing multi-degree-of-freedom adjustment of the camera module 1.

[0025] In the above structure, the first, second, third, and fourth magnetic components 23 can be partially configured as electromagnet components, partially as permanent magnet components, or all as electromagnet components, so that the control module 3 can control the polarity of the magnetic poles of each magnetic component according to the actual activity requirements of the camera module 1. For example, one of the first magnetic component 12 and the third magnetic component 22 can be configured as an electromagnet component and the other as a permanent magnet component, or both the first magnetic component 12 and the third magnetic component 22 can be configured as electromagnet components. Similarly, one of the second magnetic component 13 and the fourth magnetic component 23 can be configured as an electromagnet component and the other as a permanent magnet component, or both the second magnetic component 13 and the fourth magnetic component 23 can be configured as electromagnet components. The magnetic components configured as electromagnet components are electrically connected to the control module 3, and the specific polarity of each electromagnet component is determined according to the magnetic pole type (positive or negative) of the permanent magnet component and the activity requirements of the camera module 1.

[0026] In the above structure, the control module 3, as the core control unit, independently or in combination controls the magnetic polarity of at least some of the first, second, third, and fourth magnetic components 23 via electrical signals. When the control module 3 adjusts the polarity of the first magnetic component 12 and the third magnetic component 22, the magnetic attraction or repulsion generated between them can drive the camera module 1 to move linearly along the first direction extending from the mounting groove 211, thereby changing the relative distance between the lens and the subject. At the same time, the control module 3 can adjust the polarity distribution of the second magnetic component 13 and the fourth magnetic component 23, using the tangential magnetic torque generated between the circumferentially distributed magnetic components to drive the camera module 1 to rotate around the first direction as an axis. By precisely controlling the polarity combination and strength of each magnetic component, the control module 3 can independently or collaboratively realize the degree of freedom of movement of the camera module 1 along the first direction and the degree of freedom of rotation around the first direction, thus achieving dynamic adjustment of the shooting angle and focal length.

[0027] The first magnetic component 12 and / or the second magnetic component 13, the third magnetic component 22 and / or the fourth magnetic component 23 are electrically connected to the control module 3. For example, if the first magnetic component 12, the second magnetic component 13, the third magnetic component 22 and the fourth magnetic component 23 are all electromagnets, then they are all electrically connected to the control module 3; if the first magnetic component 12 and the third magnetic component 22 are electromagnets, then the first and third magnetic components 22 are electrically connected to the control module 3, and the second magnetic component 13 and the fourth magnetic component 23 can be permanent magnets; if the first magnetic component 12 and the fourth magnetic component 23 are electromagnets, then the first and fourth magnetic components 23 are electrically connected to the control module 3, and the second magnetic component 13 and the third magnetic component 22 can be permanent magnets. The specific design can be customized according to actual needs.

[0028] The camera module 100 provided in this embodiment significantly improves its flexibility and shooting performance through the design of multiple sets of controllable magnetic components. On the one hand, the rotational freedom of the camera module 1 around the first direction greatly expands the field of view of the lens, enabling it to capture images or video information from more directions without moving the main body 200, thus meeting the needs of multi-angle shooting. On the other hand, the movement freedom along the first direction directly realizes the electric adjustment of the lens focal length, allowing for rapid adjustment of image clarity and shooting range according to scene requirements. This dual-degree-of-freedom adjustment method overcomes the limitations of traditional complex mechanical structures and single adjustment methods, not only simplifying the transmission structure but also improving the adjustment response speed and stability. It effectively solves the problem of low information acquisition flexibility of the camera module 100, and when applied to smart wearable devices, it greatly improves the user's shooting experience and the intelligence level of the device.

[0029] Optionally, when there is no force between the second magnetic component 13 and the fourth magnetic component 23, and an attractive or repulsive force is generated between the first magnetic component 12 and the third magnetic component 22, the support base 11 drives the camera module 1 to retract or extend from the fixed base 21 along the first direction; when there is no force between the first magnetic component 12 and the third magnetic component 22, and an attractive force is generated between the second magnetic component 13 and the fourth magnetic component 23, the camera module 1 is fixed to the fixed base 21 by the support base 11; when there is no force between the first magnetic component 12 and the third magnetic component 22, and a repulsive force is generated between the second magnetic component 13 and the fourth magnetic component 23, the support base 11 drives the camera module 1 to rotate around the first direction.

[0030] Specifically, in this embodiment, when it is necessary to adjust the degree of freedom of movement of the camera module 1 in the first direction, the electromagnet components in the second magnetic component 13 and the fourth magnetic component 23 can be de-energized to achieve the effect of no force between the second magnetic component 13 and the fourth magnetic component 23. At this time, when the control module 3 controls the first magnetic component 12 and the third magnetic component 22 to generate an attractive force, the support base 11 will drive the camera module 1 to retract into the fixed base 21 in the first direction under the action of the attractive force. When the control module 3 controls the first magnetic component 12 and the third magnetic component 22 to generate a repulsive force, the support base 11 will drive the camera module 1 to extend out of the fixed base 21 in the first direction under the action of the repulsive force. Here, the camera module 1 retracting into the fixed base 21 means that the camera module 1 is close to or away from the bottom wall of the assembly slot, not that the camera module 1 is completely hidden inside the fixed base 21. In practical applications, the electromagnet components in the first magnetic component 12 and the third magnetic component 22 can be energized only when the camera module 1 needs to extend or retract into the fixed base 21. When not energized, the camera module 1 is set to the initial state.

[0031] When it is necessary to adjust the rotational degree of freedom of camera module 1 in the first direction, the electromagnet components in the first magnetic component 12 and the third magnetic component 22 can be de-energized to achieve the effect of no force between the first magnetic component 12 and the third magnetic component 22. At this time, when the control module 3 controls the second magnetic component 13 and the fourth magnetic component 23 to generate a repulsive force, the support base 11 will drive the camera module 1 to rotate around the first direction under the action of the repulsive force. When the second magnetic component 13 and the fourth magnetic component 23 generate an attractive force, the support base 11 will be attracted and fixed on the fixing base 21, thereby fixing the camera module 1.

[0032] Optionally, such as Figures 4 to 11As shown, one of the first magnetic component 12 and the second magnetic component 13 is an electromagnet component, and the other is a permanent magnet component. One of the third magnetic component 22 and the fourth magnetic component 23 is an electromagnet component, and the other is a permanent magnet component. The control module 3 is electrically connected to each electromagnet component. The control module 3 can control the polarity of each electromagnet component to make the first magnetic component 12 and the third magnetic component 22 interact to drive the camera module 1 to move around the first direction, and to make the second magnetic component 13 and the fourth magnetic component 23 interact to drive the camera module 1 to rotate around the first direction.

[0033] Specifically, in this embodiment, efficient and precise drive control is achieved by configuring the magnetic components as a combination of electromagnets and permanent magnets. In each of the first magnetic component 12, the second magnetic component 13, the third magnetic component 22, and the fourth magnetic component 23, one electromagnet component is paired with one permanent magnet component. The control module 3 only needs to be electrically connected to each electromagnet component to independently control its magnetic polarity by adjusting the current direction. This configuration simplifies the control logic and circuit structure, eliminates the need for electrical control of all magnetic components, and reduces system complexity and energy consumption.

[0034] When the control module 3 adjusts the magnetic poles of the first magnetic component 12 and the third magnetic component 22, a controllable magnetic attraction or repulsion force is generated between them, which precisely drives the camera module 1 to achieve linear displacement along the first direction and complete the focal length adjustment. At the same time, by controlling the magnetic poles of the second magnetic component 13 and the fourth magnetic component 23, a tangential magnetic torque is generated, which drives the camera module 1 to rotate around the first direction and realize the shooting angle adjustment. This ensures the independent controllability of the two motion modes and improves the drive response speed and positioning accuracy.

[0035] Furthermore, in the aforementioned structure, the permanent magnet component provides a stable fundamental magnetic field, ensuring the reliability and continuity of the magnetic force, while the electromagnet component endows the system with dynamic adjustment capabilities. The combination of the two achieves a balance between static stability and dynamic flexibility. Compared to the all-electromagnet solution, it reduces the number of electronic control components, lowering hardware costs and reducing the risk of heat generation. Compared to the all-permanent magnet solution, it endows the module with active adjustment capabilities, freeing it from the limitations of a fixed structure. This not only ensures smooth, mechanically smooth movement along and around the first direction without mechanical jamming, but also reduces mechanical wear and extends the module's lifespan through non-contact magnetic drive. The simple structure enables complex multi-dimensional adjustments, significantly improving the flexibility of the camera module 100 in acquiring image information, meeting the intelligent shooting needs of multi-angle and zoom lenses, and optimizing the user experience.

[0036] Optionally, such as Figures 4 to 11As shown, the first magnetic component 12 includes at least one first electromagnet 121, the third magnetic component 22 includes at least one third permanent magnet 221, and the at least one first electromagnet 121 is electrically connected to the control module 3; and / or, the second magnetic component 13 includes a plurality of second permanent magnets 131, the plurality of second permanent magnets 131 are spaced apart around the periphery of the support base 11 in a first direction, and the fourth magnetic component 23 includes a plurality of fourth electromagnets 231, and the number of fourth electromagnets 231 matches the number of second permanent magnets 131, and is spaced apart on the side wall of the assembly groove 211 corresponding to the positions of the plurality of second permanent magnets 131, and the plurality of fourth electromagnets 231 are all electrically connected to the control module 3.

[0037] Specifically, in this embodiment, precise linear drive along the first direction is achieved through the pairing of the first electromagnet 121 and the third permanent magnet 221. The control module 3 adjusts the magnetic polarity of the first electromagnet 121 to generate a controllable attraction and repulsion force with the third permanent magnet 221, driving the camera module 1 to move smoothly and complete the focus adjustment. This configuration simplifies the linear drive structure, utilizes the permanent magnet to provide a stable magnetic field, and the electromagnet achieves dynamic control, balancing drive reliability and control flexibility, and ensuring the accuracy and response speed of focus adjustment.

[0038] Furthermore, the matching number and circumferential alignment of the second permanent magnet 131 and the fourth electromagnet 231 provide a uniform tangential torque for rotational drive. The control module 3 controls the polarity of multiple fourth electromagnets 231 in a time-division or synchronous manner, which interact with the second permanent magnet 131 to generate a balanced rotational driving force, enabling the camera module 1 to rotate smoothly around the first direction. This ensures the stability of the rotational motion and the accuracy of angle control, effectively avoiding eccentricity or jamming, expanding the shooting angle, and improving the flexibility and controllability of the imaging perspective.

[0039] Optionally, such as Figures 4 to 11 As shown, both the support base 11 and the fixed base 21 are configured as columnar structures extending along the first direction; the support base 11 has multiple first grooves extending along the first direction at intervals on its periphery, and multiple second permanent magnets 131 are respectively embedded in each of the first grooves; the side wall of the assembly groove 211 has multiple second grooves 212 extending along the first direction at intervals, and multiple fourth electromagnets 231 are respectively embedded in each of the second grooves 212; the magnetic poles of each fourth electromagnet 231 can correspond one-to-one with the magnetic poles of each second permanent magnet 131, so that the control module 3 drives the camera module 1 to rotate around the first direction by controlling the polarity of the magnetic poles of each fourth electromagnet 231. Specifically, in this embodiment, by designing the support base 11 and the fixed base 21 as columnar structures extending along the first direction, a compact and integrated layout of the rotation drive component is achieved. The support base 11 can be set as a cylinder, and the assembly groove 211 is also designed as a circular cross section to improve the smoothness of the camera module 1 rotating around the first direction.

[0040] The support base 11 has multiple first grooves extending along the first direction on its periphery, in which the second permanent magnet 131 is embedded, which not only ensures that the permanent magnet is firmly installed and accurately positioned, but also makes the magnetic field distribution on the periphery uniform. The assembly groove 211 has multiple second grooves 212 on its side wall, in which the fourth electromagnet 231 is embedded, so that the electromagnet and the permanent magnet form a one-to-one magnetic pole relationship, ensuring efficient transmission of magnetic force.

[0041] The recessed embedding structure in the above structure avoids the outward protrusion of the magnetic components, optimizes the overall shape of the module, and improves space utilization. The control module 3 independently controls the magnetic polarity of each fourth electromagnet 231, generating controllable attraction and repulsion forces with the corresponding second permanent magnet 131, forming a balanced tangential torque, driving the camera module 1 to rotate smoothly around the first direction. This not only ensures the stability, accuracy, and response speed of the rotational motion, but also reduces mechanical wear and extends service life through non-contact magnetic drive, effectively expands the shooting angle, and improves the imaging flexibility and user experience of the camera module 100.

[0042] Optionally, such as Figures 6 to 7 As shown, each second permanent magnet 131 is arranged in pairs, and each pair of second permanent magnets 131 is symmetrically arranged on the periphery of the support base 11. The position of each fourth electromagnet 231 matches the position of each second permanent magnet 131. Specifically, in this embodiment, by symmetrically arranging the second permanent magnets 131 in pairs around the support base 11 and precisely matching the positions of the fourth electromagnet 231 and the permanent magnets, the force and control characteristics of the rotation drive are effectively optimized. The symmetrical arrangement ensures a uniform circumferential magnetic field distribution, avoiding eccentricity and swaying caused by unilateral force, thus improving the stability and coaxiality of the rotation process. Position matching ensures precise alignment of the electromagnet and permanent magnet poles, resulting in efficient transmission of magnetic force. The control module 3 can adjust the polarity of the electromagnet to generate a balanced tangential torque, achieving precise angle adjustment around the first direction.

[0043] In one embodiment, when the camera module 100 is in its initial position (for example, at this time, the second end of the support base 11 can contact the bottom wall of the mounting groove 211, the first magnetic component 12 and / or the second magnetic component 13 are not energized and are in a state of no force; each second permanent magnet 131 is respectively fixed to the fourth electromagnet 231 by attraction), reference Figure 6 , Figure 7 and Figure 18 Since the magnetic poles of each of the second permanent magnets 131 do not change, when the control module 3 controls the direction of the current in the electromagnets so that the negative poles of each of the fourth electromagnets 231 are paired with the positive poles of each of the second permanent magnets 131, the camera module 1 will be tightly attracted and fixed to the bracket assembly 2 by the four pairs of magnets, and the appearance will be that the camera module 1 is firmly fixed. When the camera needs to rotate, it is only necessary to reverse the polarity of each of the fourth electromagnets 231, so that the positive poles of each of the fourth electromagnets 231 face the positive poles of the second permanent magnets 131. Under the action of repulsion, the camera module 1 will quickly move along the direction of the current. Figure 20 The hollow arrow in the middle rotates in the direction.

[0044] Furthermore, the angle by which the camera module 1 stops rotating depends on which fourth electromagnet 231, in the direction of rotation, has a polarity opposite to its initial polarity. Figure 20 For example, when camera module 1 rotates around the hollow arrow direction due to repulsive force from the position of the upper fourth electromagnet 231, and reaches the position of the lower fourth electromagnet 231, when the magnetic pole indicated by the question mark on the lower fourth electromagnet 231 is negative (i.e., opposite to the initial position), camera module 1 will be instantly attracted and fixed in place. (Refer to...) Figure 19 , is from the initial position ( Figure 19 Rotate 45° to the position shown, otherwise it will continue to rotate.

[0045] Optionally, such as Figures 12 to 15 As shown, the first magnetic component 12 includes two first electromagnets 121, both of which are electrically connected to the control module 3; two positioning grooves 111 are provided on the end face of the second end of the support base 11, and the two first electromagnets 121 are respectively embedded in the two positioning grooves 111; the third magnetic component 22 includes a third permanent magnet 221, which is annular and embedded in the bottom wall of the assembly groove 211; the magnetic poles of the two first electromagnets 121 are opposite to the magnetic poles of the third permanent magnet 221, so that the control module 3 can drive the camera module 1 to move along the first direction by controlling the polarity of the magnetic poles of each first electromagnet 121.

[0046] Specifically, in this embodiment, by providing two positioning grooves 111 on the second end face of the support base 11, two first electromagnets 121 are respectively embedded therein, achieving precise positioning and firm assembly of the electromagnets, preventing them from shifting during movement, and ensuring the stability of the magnetic field's point of application. The third magnetic component 22 adopts a ring-shaped third permanent magnet 221 and is embedded in the bottom wall of the assembly groove 211. Its ring structure can provide a continuous and uniform magnetic field, forming a stable magnetic pole relationship with the two first electromagnets 121.

[0047] In one embodiment, reference Figures 12 to 15,as well as Figure 21 and Figure 22 The principle by which camera module 1 moves (extends) along the first direction via two second electromagnets and a ring-shaped third permanent magnet 221 is as follows: Wherein, as Figure 14 and Figure 21 The diagram shows the positions of each component when the camera module 1 is in its initial position. At this time, the camera module 1 is at the bottom of the assembly slot 211, and the polarities of the two first electromagnets 121 and the third permanent magnet 221 are opposite, making the camera module 1 firmly fixed in the assembly slot 211. When it is necessary to push the camera module 1 further, the two first electromagnets 121 at the bottom of the camera module 1 begin to have the same polarity as the third permanent magnet 221. Under the action of a strong repulsive force, the camera module 1 is pushed to the farthest point, which appears as if the camera protrudes further outward. (See reference...) Figure 15 and Figure 22 .

[0048] The above structural layout ensures a balanced distribution of magnetic forces between the support base 11 and the fixed base 21, effectively preventing problems such as eccentricity and tilting of the camera module 1 when it moves along the first direction. This improves the coaxiality and assembly reliability of the overall module structure and provides structural assurance for the smooth operation of linear drive.

[0049] Optionally, such as Figures 13 to 15 As shown, the second end of the camera module 1 is detachably mounted in the mounting slot 211.

[0050] Specifically, in this embodiment, the second end of the camera module 1 is detachably mounted in the mounting slot 211 of the bracket assembly 2, which significantly improves the maintainability, expandability, and application flexibility of the camera module 100. The detachable structure facilitates the independent assembly and disassembly of the camera module 1. When components such as the lens and magnetic components malfunction or are damaged, the camera module 1 can be replaced individually without replacing the entire bracket assembly 2, effectively reducing maintenance costs and material waste, and simplifying the after-sales process.

[0051] Meanwhile, the detachable structural design supports the adaptation of camera modules 1 of different specifications or functions to the same bracket assembly 2, realizing modular combination and functional upgrades of the modules to meet diverse shooting needs. In addition, the detachable assembly facilitates assembly, debugging and quality inspection during the production process, improving production efficiency, and also makes it convenient for users to quickly replace modules according to scenario requirements, enhancing the versatility and practicality of the equipment, and optimizing the overall life cycle user experience of the camera module 100.

[0052] Optionally, such as Figures 13 to 15As shown, the camera module 1 also includes an airbag, which is disposed on the periphery of the second end of the support base 11. A limiting groove 213 is provided on the side wall of the mounting groove 211. When the airbag is inflated, it can cooperate with the limiting groove 213 to limit the position of the camera module 1 in the first direction. When the airbag is deflated, it can disengage from the limiting groove 213 so that the camera module 1 can be separated from the bracket assembly 2.

[0053] Specifically, in this embodiment, an airbag is provided on the circumference of the second end of the support base 11, and a limiting groove 213 is correspondingly provided on the side wall of the assembly groove 211. The inflation and deflation of the airbag achieves precise positioning and reliable fixation of the camera module 1. After the airbag is inflated, it fits tightly with the limiting groove 213 to form a circumferentially encircling limiting structure, effectively restricting the movement of the camera module 1 in the first direction, while providing flexible buffering to reduce the movement of the camera module 1 during operation (refer to...). Figure 14 and Figure 15 The airbag effectively reduces vibration and impact, improving imaging stability. Furthermore, the cooperation between the airbag and the bottom wall of the limiting groove 213 and assembly groove 211 enables stroke control of the initial and extended positions of the camera module 1 in the first direction. This non-rigid contact positioning method avoids wear and jamming caused by mechanical hard limiting, ensuring assembly accuracy while enhancing the structural stability and anti-interference capability of the module under complex working conditions.

[0054] Furthermore, the airbag inflation / deflation design gives the camera module 100 highly efficient detachability. In the deflated state, the airbag retracts and disengages from the limiting groove 213, allowing the camera module 1 to be easily extracted from the bracket assembly 2, achieving non-destructive separation and greatly simplifying the assembly and disassembly process. This method requires no tools, is convenient to operate, facilitates rapid assembly and debugging during the production phase, and also allows for individual replacement or repair of the camera module 1 during later maintenance, reducing maintenance costs and difficulty. Simultaneously, the cyclical nature of inflation positioning and deflation separation improves the module's repeatability and accuracy, balancing fixed reliability and disassembly flexibility, optimizing the product's overall lifecycle user experience. The inflation and deflation of the airbag can be achieved via an inflation motor.

[0055] Optionally, such as Figures 9 to 13 As shown, the second end of the fixing base 21 is also provided with a wiring hole 214 communicating with the assembly groove 211, and a wire group 24 is provided in the wiring hole 214; the control module 3 includes a circuit board 31 and a plug-in socket 32 ​​connected to the circuit board 31, the second end of the fixing base 21 is plugged into the plug-in socket 32, and each magnetic component is electrically connected to the circuit board 31 through the wire group 24.

[0056] Specifically, in this embodiment, by providing a wiring hole 214 communicating with the mounting groove 211 at the second end of the fixing base 21 and embedding a wire assembly 24, the orderly and integrated electrical connections within the camera module 100 are achieved. The wiring hole 214 provides a dedicated and concealed routing channel for the wire assembly 24, avoiding exposed or tangled wires, improving structural compactness and space utilization, while effectively protecting the wires from wear and tear, and enhancing the reliability and safety of the electrical connections.

[0057] The integrated design of the circuit board 31 and connector 32 of the control module 3, along with the plug-in structure at the second end of the mounting base 21, enables rapid and precise electrical connection between the bracket assembly 2 and the control module 3. Each magnetic component is directly connected to the circuit board 31 via the wire group 24, simplifying the assembly process and improving production and debugging efficiency. This solution ensures the stability of the electrical connection while optimizing the overall structural layout of the module, providing a reliable electrical foundation for the precise control of the magnetic components and enhancing the module's integration and practicality. The circuit board 31 can be an FPC (flexible printed circuit board) to adapt to the internal structure of different smart wearable devices.

[0058] According to the second aspect of this application, such as Figures 16 to 23 As shown, a smart wearable device is provided, including: a device body 200 and one or more camera modules 100 of the first aspect, the camera modules 100 being mounted on the device body 200.

[0059] Specifically, in this embodiment, by integrating the camera module 100 provided in the first aspect onto the device body 200, flexible control of the imaging function of the wearable device is achieved. The camera module 100 possesses dual-degree-of-freedom adjustment capabilities, allowing movement along and rotation around a first direction. This enables flexible adjustment of the shooting angle and focal length without changing the wearing position of the device body 200, greatly expanding the framing range and imaging flexibility of the wearable device and meeting the needs of multi-angle and multi-scene shooting. Simultaneously, the integrated design makes the device structure compact, balancing portability and functionality, and adaptable to wearable scenarios such as wrist and head.

[0060] In camera module 100, the magnetically driven, non-contact adjustment method reduces mechanical wear, improving device durability and quiet operation. Simultaneously, detachable assembly and modular design facilitate maintenance and upgrades, reducing operating costs. This solution combines highly flexible camera technology with smart wearables, optimizing the shooting experience, enriching device application scenarios, and enhancing product competitiveness and user experience. In practical applications, one or more camera modules 100 can be installed on the main body 200 of the smart wearable device. In one embodiment, such as Figures 16 to 17As shown, the smart wearable device is a smart glasses. The main body 200 is the lens of the smart glasses. The lens includes a front shell 4 and a rear shell 42. The front shell 4 and the rear shell 42 are fastened together to form a receiving cavity. The front shell 4 is provided with an assembly hole 41 that communicates with the receiving cavity. The camera module 100 is disposed in the assembly hole 41, and the lens of the camera module 1 faces the outside of the lens. The control module 3 is disposed in the receiving cavity.

[0061] In the above structure, the front shell 4 and the rear shell 42 are fastened together to form a receiving cavity, which protects the internal control module 3 and achieves a compact structure. The front shell 4 has a mounting hole 41 to embed the camera module 100 with the lens facing outwards, ensuring an unobstructed shooting angle that conforms to the human eye's perspective, enhancing the realism and immersiveness of the shooting experience. The control module 3 is built into the receiving cavity, optimizing the spatial layout, avoiding external interference, and ensuring stable electrical connections and precise control. This integrated design makes the smart glasses both lightweight and capable of imaging. The outward-facing lens facilitates first-person perspective shooting, and the integrated structure improves wearing comfort and device reliability, expands the application scenarios of smart glasses, and enhances the user's image recording experience.

[0062] Optionally, the smart wearable device is smart glasses, which include a frame and two temples 202 connected to both sides of the frame 201. A camera module 100 is mounted on the frame 201 and located at the front end of the temples 202, or mounted on the frame 201 at a position corresponding to the user's nose bridge. That is, to obtain more viewing angles, the camera module 100 can be placed in different positions to capture more perspectives, further expanding the applicable scenarios of the smart glasses.
