Description

Technical Field

[0001] This application relates to the field of wearable device technology, and more particularly to a wearable device with a camera module. Background Technology

[0002] Traditional ear-hook headphones typically have limited functionality, primarily for audio playback or calls. However, with the growing demand for more multifunctional portable electronic devices, wearable devices integrating camera capabilities have emerged. These devices attempt to combine audio playback with video recording, providing users with a more convenient experience.

[0003] However, existing wearable devices with camera functions have structural design shortcomings. The camera module is usually directly fixed to the audio module, making it impossible to flexibly adjust the shooting angle and direction. When users need to shoot from different angles, they often need to adjust the position of the entire wearable device or change their head posture, which is not only cumbersome but may also affect the comfort and stability of wearing the device. At the same time, the fixed positional relationship between the camera module and the audio module in traditional designs limits the shooting range of the camera module, preventing it from effectively extending to the ideal shooting position and resulting in poor functionality.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Traditional ear-hook headphones typically have limited functionality, primarily for audio playback or calls. However, with the growing demand for more multifunctional portable electronic devices, wearable devices integrating camera capabilities have emerged. These devices attempt to combine audio playback with video recording, providing users with a more convenient experience.

[0023] However, existing wearable devices with camera functions have structural design shortcomings. The camera module is usually directly fixed to the audio module, making it impossible to flexibly adjust the shooting angle and direction. When users need to shoot from different angles, they often need to adjust the position of the entire wearable device or change their head posture, which is not only cumbersome but may also affect the comfort and stability of wearing the device. At the same time, the fixed positional relationship between the camera module and the audio module in traditional designs limits the shooting range of the camera module, preventing it from effectively extending to the ideal shooting position and resulting in poor functionality.

[0024] Based on this, see Figures 1 to 4 As shown, this utility model embodiment provides a wearable device 10 with a camera module, which includes a wearing structure 100, an audio module and a camera module; the audio module is disposed on the wearing structure 100; the camera module 300 includes a camera module 310 and an extension component for extending the camera module 310 forward relative to the audio module, the extension component is connected to the camera module 310 and the audio module respectively, and the extension component is rotatably connected to the audio module.

[0025] The wearable device 10 with a camera module in this embodiment adopts a structural design in which the camera module 300 includes a camera module 310 and an extension component. The extension component is connected to the camera module 310 and the audio module respectively. The extension component is rotatably connected to the audio module, which effectively solves the technical problem in traditional devices where the camera module 310 is directly fixed to the audio module, resulting in the inability to flexibly adjust the shooting angle.

[0026] In the camera module 300 of this embodiment, the extension component allows the camera module 310 to extend outward from the audio module to a more suitable shooting position, overcoming the limitation of the fixed positional relationship between the camera module 310 and the audio module in traditional designs and effectively expanding the shooting range. Simultaneously, the rotating connection structure between the extension component and the audio module allows the user to adjust the orientation of the camera module 310 by rotating the extension component, achieving multi-angle shooting functionality and simplifying operation.

[0027] The wearable device 10 in this embodiment is designed so that users can adjust the angle without adjusting the position of the entire wearable device 10 or changing their head posture, maintaining wearing comfort and stability while improving the convenience and flexibility of shooting. The configuration of the extension components not only optimizes the spatial layout of the camera module 310, but also ensures the effective integration of the camera and audio functions, resulting in a compact and reasonable structure.

[0028] Specifically, the wearing structure 100 is worn on the user's head and can be an arc-shaped structure that wraps around the user's head. The arc design of the wearing structure 100 conforms to the natural curve of the user's head, providing a comfortable wearing experience. Its material can be lightweight and elastic plastic or metal, ensuring structural strength while reducing overall weight. The inner side of the wearing structure 100 can be padded or have anti-slip texture to enhance the fit and stability with the user's head, preventing slippage or displacement during use. The length and bending angle of the wearing structure 100 are ergonomically optimized to adapt to different user head sizes, ensuring wide applicability and good wearing stability.

[0029] Specifically, the audio module includes an audio module and an audio housing 200. The audio housing 200 is connected to the wearing structure 100. The audio module is located inside the audio housing 200. The audio housing 200 has an arc-shaped guide groove 211. The extension component has a guide pin 3311. The extension component is rotatably connected to the audio housing 200, and the guide pin 3311 slides with the guide groove 211.

[0030] The guide pin 3311 and guide groove 211 are designed to restrict and guide the rotation range of the extension component, ensuring that the extension component maintains a stable and controlled state during rotation. The arc-shaped structure of the guide groove 211 matches the rotation trajectory of the extension component, providing stable rotational support and guidance for the extension component.

[0031] This structural design not only ensures the smoothness and stability of the extension component's rotation, but also effectively limits the rotation angle of the extension component, preventing the camera module 310 from deviating from the ideal shooting range during rotation. Simultaneously, the cooperation between the guide groove 211 and the guide pin 3311 ensures good positioning and repeatability of the extension component during rotation, allowing the user to accurately position the camera module 310 to the desired location each time they adjust its angle.

[0032] This design of rotation limit and guide mechanism effectively solves the problems of inflexible angle adjustment and poor positioning accuracy of camera modules in traditional wearable camera devices. Users can easily and quickly adjust the shooting angle and direction of the camera module 310 by simply rotating the extension component to meet various shooting needs. This design not only improves ease of use but also ensures the stability and reliability of the captured images.

[0033] In one embodiment, a damping sheet or spring sheet may be provided between the audio housing 200 and the extension component to achieve a limiting function. The damping sheet may be made of rubber or polyurethane and is disposed between the contact surfaces of the extension component and the audio housing 200. The damping sheet generates appropriate frictional resistance through elastic deformation, so that the extension component produces a smooth damping feel during rotation, preventing the extension component from rotating excessively due to inertia, while providing the user with good tactile feedback.

[0034] The spring clips can be made of stainless steel or spring steel and are positioned near the rotation axis of the extension component. The elastic force of the spring clips applies a preload to the extension component, allowing it to form a stable positioning point at a specific angle. The number of spring clips can be one, two, or more; there is no fixed limit. Using multiple spring clips provides a more uniform distribution of preload, improving the positioning accuracy and stability of the extension component. Multiple positioning points also allow users to quickly adjust the camera module 310 to their preferred shooting angle. The elastic coefficient of the spring clips can be selected based on the required positioning force, ensuring sufficient positioning stability without making rotation operation too difficult.

[0035] These limiting structures not only improve the stability and controllability of the extended component's rotation, but also provide users with clear angle positioning feedback, making the angle adjustment of the camera module 310 more precise and convenient. Damping plates and springs can be used individually or in combination, depending on specific design requirements and usage scenarios. When multiple limiting structures are used simultaneously, they can cooperate to provide more comprehensive rotation control and positioning functions, further enhancing the user experience and reliability of the wearable device 10.

[0036] In one embodiment, the audio housing 200 includes a housing body 210 and a fixing part 220. The fixing part 220 is connected to the housing body 210 and has a rotating hole 221. The extension component includes an extension 320 and a connecting seat 330. The extension 320 is connected to the connecting seat 330 and the camera module 310. The connecting seat 330 includes a connecting part 331 and a rotating shaft 332. The connecting part 331 is connected to the rotating shaft 332 and the extension 320. The rotating shaft 332 passes through the rotating hole 221 and rotates with the fixing part 220.

[0037] The fixing part 220 can be a cylindrical tubular structure, with its inner wall forming the wall surface of the rotating hole 221. The fixing part 220 can be made of a high-strength and wear-resistant metal material, such as aluminum alloy, stainless steel, or engineering plastic, to ensure that it can withstand the repeated rotation of the rotating shaft 332 without wear or deformation during long-term use. The outer surface of the fixing part 220 can be provided with positioning structures such as protrusions or grooves to facilitate precise positioning and secure connection with the shell body 210.

[0038] The rotating shaft 332 serves as a rotating support element for the connecting seat 330. Its length should match the thickness of the fixing part 220 to ensure that the rotating shaft 332 can be fully inserted into the rotating hole 221 and form a stable rotating fit with the fixing part 220.

[0039] The rotating hole 221 and the rotating shaft 332 cooperate to achieve a rotatable connection between the connector 330 and the audio housing 200. The rotating shaft 332 and the rotating hole 221 cooperate to form a rotating pair, with the rotating shaft 332 as the inner ring and the rotating hole 221 as the outer ring, forming a cylindrical connection between them, allowing the connector 330 to rotate around the axis of the rotating shaft 332. This rotatable connection method has the technical advantages of smooth rotation, strong load-bearing capacity, and compact structure, and can provide stable angle adjustment function for the camera module 310.

[0040] The guide pin 3311 is located on the side of the connecting part 331 facing the audio housing 200, so that it can form a good sliding fit with the arc-shaped guide groove 211 on the audio housing 200. The guide pin 3311 can be cylindrical, conical or spherical, etc., and is not limited to one shape here.

[0041] Furthermore, the pivot 332 has a connection hole 3321, and the connection hole 3321 is coaxially arranged with the rotation hole 221. The extension 320 has a cable channel connected to the camera module 310 inside, and the connection hole 3321 is connected to the cable channel and the internal space of the audio housing 200 respectively.

[0042] The connecting hole 3321 of the rotating shaft 332 extends through the shaft 332 along its axial direction, forming a through-hole structure with a circular or elliptical cross-section. The diameter of the connecting hole 3321 can be designed according to the number and thickness of the cables, and is not limited to a single size. The inner wall of the connecting hole 3321 can be chamfered or have a guide chamfer to prevent damage to the cables during installation due to sharp edges. The connecting hole 3321 can be processed by drilling, stamping, or laser cutting. Drilling has the advantages of high precision and good surface finish, stamping has the advantages of high production efficiency and low cost, and laser cutting has the advantages of high processing precision and small heat-affected zone.

[0043] The coaxial arrangement of the connecting hole 3321 and the rotating hole 221 ensures that the cable can bend and deform around the same axis during the rotation of the connector 330, avoiding additional stress concentration due to axis offset, and ensuring that the cable will not experience abnormal wear or twisting during rotation.

[0044] The cable channel inside the extension member 320 extends along the length of the extension member 320, forming a cable transmission path connecting the camera module 310 and the connection hole 3321. The cross-sectional shape of the cable channel can be designed as circular, square, or racetrack-shaped. A circular cross-section offers advantages such as uniform stress distribution and simple manufacturing; a square cross-section offers advantages such as high space utilization and neat cable arrangement; and a racetrack-shaped cross-section combines the advantages of both circular and square shapes, offering strong adaptability. The dimensions of the cable channel should match the dimensions of the connection hole 3321 to ensure smooth cable passage without obstruction. The inner wall of the cable channel can be fitted with an anti-wear sleeve or coated with a lubricating coating to reduce friction between the cable and the channel wall, extending the cable's service life.

[0045] The connection hole 3321 connects to both the cable channel and the internal space of the audio housing 200, forming a complete cable transmission path from the internal space of the audio housing 200 to the camera module 310. This connection design allows the cable to originate from the circuit board or signal processing unit inside the audio housing 200, pass sequentially through the connection hole 3321 and the cable channel, and finally reach the camera module 310, thus achieving power supply and signal transmission functions. A sealing ring or dust cover can be installed at the connection point between the connection hole 3321 and the internal space of the audio housing 200 to prevent external dust or moisture from entering the interior of the audio housing 200, protecting the normal operation of the internal electronic components.

[0046] The cable can enter through the connection hole 3321 and can pass through the extension member 320 before connecting to the camera module 310. The cable type can include power cables, signal transmission cables, and data transmission cables. The power cable provides power to the camera module 310, the signal transmission cable transmits control signals, and the data transmission cable transmits image or video data captured by the camera module 310. The number of cables can be one, two, three, or more, depending on the functional requirements of the camera module 310, and is not limited here. Using multiple cables allows for separate transmission of power and signals, improving the system's anti-interference capability and transmission stability, while also supporting multiple functional modes of the camera module 310.

[0047] The extension member 320 and connector 330 protect the cable while ensuring signal connection and transmission even when the camera module 310 can rotate. The tubular structure of the extension member 320 provides a sealed protective space for the cable, effectively blocking damage from dust, moisture, and mechanical impact from the external environment. The rotating design of the connector 330 allows the cable to bend and deform accordingly with the angle adjustment of the camera module 310. This deformation is controllable and predictable, avoiding cable breakage or poor contact caused by forced bending.

[0048] Specifically, the curvature of the guide groove 211 is no greater than 180°.

[0049] The curvature of the guide groove 211 can be 30°, 60°, 90°, 120°, 150°, or 180°, depending on the actual design requirements, and is not a single limitation. When the curvature of the guide groove 211 is less than 30°, the angle adjustment range of the camera module 310 is relatively limited, which may not meet the user's shooting needs in different scenarios, affecting the user experience and functional practicality. When the curvature of the guide groove 211 is greater than 180°, the space occupied by the guide groove 211 on the audio housing 200 increases, which may lead to an increase in the overall size of the audio housing 200. At the same time, an excessively large curvature design will weaken the structural strength of the housing body 210 at the guide groove 211, affecting the mechanical stability of the audio housing 200.

[0050] The curvature design of the guide groove 211 is based on the principles of geometry and mechanical kinematics. The curvature angle determines the length of the movement trajectory of the guide pin 3311 within the guide groove 211 and the maximum rotation angle of the camera module 310. When the guide pin 3311 slides along the curved trajectory of the guide groove 211, the arc length of its movement trajectory is directly proportional to the curvature of the guide groove 211. The larger the curvature, the longer the sliding distance of the guide pin 3311, and correspondingly, the larger the angle adjustment range of the camera module 310. There is a geometric correspondence between the curvature angle of the guide groove 211 and the rotation angle of the camera module 310. By precisely controlling the curvature design of the guide groove 211, the rotation range of the camera module 310 can be precisely limited.

[0051] The arc-shaped profile of the guide groove 211 can adopt geometric shapes such as circular arc, elliptical arc, or compound curve. Among them, the circular arc guide groove 211 has the advantages of simple processing and smooth movement; the elliptical arc guide groove 211 has the advantages of adjustable movement trajectory and strong adaptability; and the compound curve guide groove 211 has the advantages of customizable movement characteristics and diverse functions. The depth of the guide groove 211 can be designed according to the size of the guide pin 3311 to ensure that the guide pin 3311 can slide stably within the guide groove 211 without dislodging.

[0052] This design allows the camera module 310 to easily switch between folded and unfolded states. In the folded state, the camera module 310 is stored near the audio housing 200, with a relatively compact position relative to the audio housing 200. In this state, the camera module 310 does not occupy additional space, facilitating the storage and carrying of the entire wearable device. In the unfolded state, the camera module 310 extends away from the audio housing 200, obtaining a wider field of view and a better shooting angle, allowing the camera module 310 to fully utilize its shooting function.

[0053] During the transition of the camera module 310 from a folded state to an unfolded state, the guide pin 3311 slides along an arc-shaped trajectory within the guide groove 211 from the starting position to the ending position. Simultaneously, the connecting seat 330 rotates around the pivot 332, causing the extension 320 and the camera module 310 to adjust their angles together. This motion mechanism is based on a composite motion principle of sliding and rotational guidance. The cooperation between the guide groove 211 and the guide pin 3311 provides constraint and guidance for the motion trajectory, while the cooperation between the pivot 332 and the rotation hole 221 provides rotational support and load-bearing function. The two guiding mechanisms work together to achieve a smooth and controllable state transition of the camera module 310.

[0054] The technological benefits of the state-switching feature are reflected in both ease of use and functional adaptability. In terms of ease of use, users can flexibly adjust the position and angle of the camera module 310 according to actual shooting needs. When not using the camera function, the camera module 310 can be folded and stored, reducing the overall size of the wearable device. When the camera function is needed, the camera module 310 can be unfolded to a suitable position to achieve the desired shooting effect. In terms of functional adaptability, the state-switching capability of the camera module 310 allows it to adapt to different usage scenarios and shooting requirements. For example, in the folded state, it can be used for covert or close-up shooting, while in the unfolded state, it can be used for wide-angle or long-distance shooting, improving the functional versatility and practical value of the wearable device.

[0055] In one embodiment, the guide groove 211 and the guide pin 3311 are located on the same side of the rotation axis of the extension member, and the extension member is oriented away from the wearing structure 100.

[0056] The configuration of the guide groove 211 and the guide pin 3311 ensures that the reaction force generated when the guide pin 3311 slides in the guide groove 211 is mechanically balanced with the center of gravity distribution of the extension component, avoiding instability in the rotation of the extension component due to eccentric load. The axis of rotation refers to the geometric axis of the connecting seat 330 when it rotates around the rotating shaft 332. This axis coincides with the center line of the rotating shaft 332 and is coaxial with the center line of the rotating hole 221.

[0057] The specific positional relationship between the guide groove 211 and the guide pin 3311 on the same side of the rotation axis can be described by geometric projection. When a coordinate system is established with the rotation axis as the reference, the geometric center of the guide groove 211 and the geometric center of the guide pin 3311 are projected into the same quadrant of the rotation axis in a plane perpendicular to the rotation axis. This arrangement ensures that the motion trajectory of the guide pin 3311 sliding along the guide groove 211 and the rotation trajectory of the connecting seat 330 form an orderly motion relationship in space, avoiding motion interference and spatial conflict problems.

[0058] The extension 320 is positioned away from the wearing structure 100, ensuring that the camera module 310 has an unobstructed field of view during operation. Since the wearing structure 100 serves as the connection between the wearable device 10 and the user's body, its spatial position is relatively fixed. The orientation design of the extension 320 must consider its spatial relationship with the wearing structure 100 to ensure that the camera module 310's shooting function is not limited by the space of the wearing structure 100. The orientation angle of the extension 320 can be changed by adjusting the rotation angle of the connecting base 330, thereby enabling flexible adjustment of the camera module 310's shooting direction.

[0059] In this embodiment, after the wearable device 10 is worn, the wearing structure 100 can be located behind the user's head, the camera module 310 can face the front of the user, and the guide groove 211 and guide pin 3311 can be located behind the rotation axis of the camera module 300. The wearing method of the wearable device 10 is based on ergonomic design principles, and the way the wearing structure 100 fits against the user's head can provide stable support and a comfortable wearing experience. The design of the wearing structure 100 being located behind the user's head makes the center of gravity distribution of the wearable device 10 more even, reducing the burden on the user's neck caused by the forward tilting moment. The audio housing 200 forms a stable positional relationship with the user's head through the wearing structure 100, providing a reliable mounting base for the camera module 300.

[0060] The camera module 310's forward-facing configuration allows it to capture the user's field of view, making it suitable for various applications such as first-person perspective shooting, environmental recording, and interactive scene shooting. The shooting direction of the camera module 310 can be adjusted by rotating the connector 330, allowing the user to adjust the camera module 310 to the optimal shooting angle according to actual shooting needs.

[0061] The arrangement of the guide groove 211 and guide pin 3311 behind the rotation axis of the camera module 300 is based on the principle of spatial layout optimization. This configuration allows the guide mechanism to be concentrated in the rear area of ​​the camera module 300, providing a larger unobstructed space for the front shooting area of ​​the camera module 310. The area behind the rotation axis refers to the space away from the user's forward field of vision, with the rotation axis as the boundary. The utilization of this space will not affect the shooting function of the camera module 310. The specific position of the guide groove 211 behind the rotation axis can be optimized according to the structural layout of the audio housing 200 to ensure no spatial conflict with other functional modules inside the audio housing 200. In another embodiment, the guide groove 211 and guide pin 3311 can also be located in front of the rotation axis. The area in front of the rotation axis refers to the space facing the user's forward field of vision, with the rotation axis as the boundary, and will not be elaborated further here.

[0062] Furthermore, in the direction of the optical axis of the camera module 310, the distance between the end of the camera module 310 furthest from the audio module and the audio module is no more than 90mm. This design helps to maintain the compact size and balanced center of gravity distribution of the entire wearable device 10.

[0063] Specifically, when the distance between the far end of the camera module 310 and the audio module exceeds 90mm, the overall size of the wearable device 10 will increase accordingly, which is detrimental to the user's wearing experience and portability. At the same time, an excessively long lever arm will also increase the amplitude of shooting sway caused by user head movements, affecting the shooting stability of the camera module 310. Keeping this distance within 90mm not only maintains the compact size of the wearable device 10 but also effectively reduces the interference of user head movements on the shooting stability of the camera module 310.

[0064] Specifically, the distance design within 90mm provides sufficient extension space for the camera module 310 to achieve an ideal shooting angle and field of view, while ensuring that the overall size is not too bulky and maintains good wearing comfort. At the same time, the shorter lever arm length also reduces the impact of the user's head movements on the shooting stability of the camera module 310, avoiding image shake or blur. This distance design takes into account multiple factors such as functionality, ergonomics, and structural layout, reflecting the systematic and comprehensive design of the wearable device 10.

[0065] In practical applications, the distance between the camera module 310 and the audio module can be adjusted appropriately based on the specific usage scenario and user group characteristics. For example, for scenarios requiring prolonged wear, the distance can be shortened to improve wearing stability; for scenarios requiring wide-angle shooting effects, the distance can be increased to optimize the shooting field of view of the camera module 310. In short, this distance design needs to strike a balance between functionality, user experience, and structural compactness.

[0066] In another embodiment, the extension 320 is a malleable structure. A malleable structure refers to a material structure that can change shape under external force and retain its deformed shape after the external force is removed. The malleable structure design of the extension 320 is based on the principle of plastic deformation in materials mechanics. When the applied external force exceeds the elastic limit of the material but does not reach the breaking strength, the material will undergo irreversible plastic deformation, and this deformation can maintain a stable state after the external force is removed.

[0067] The malleable structure of extension 320 can be achieved using a variety of materials, including highly malleable metallic materials such as aluminum alloys, copper alloys, low-carbon steel, and shape memory alloys, as well as polymeric materials with some malleability such as polyethylene and polypropylene. Aluminum alloys offer advantages such as light weight, moderate strength, and good stability after plastic deformation, making them suitable for wearable devices with strict weight requirements. Copper alloys offer excellent malleability, good electrical conductivity, and strong corrosion resistance, making them suitable for applications requiring both plastic deformation adjustment and electrical connection. Low-carbon steel offers advantages such as a wide range of plastic deformation, low cost, and good processing performance, making it suitable for mass production applications where cost control is a priority.

[0068] The cross-sectional shape of the extension 320 can be designed as circular, square, rectangular, or irregular, with different cross-sectional shapes corresponding to different bending performance and deformation characteristics. A circular cross-sectional extension 320 exhibits equal bending resistance in all directions, enabling omnidirectional bending adjustment. A square cross-sectional extension 320 has different bending resistance in two main directions, providing directional bending advantages. A rectangular cross-sectional extension 320 has distinct strong and weak axis directions, with bending deformation primarily occurring in the weak axis direction, enabling controllable unidirectional bending.

[0069] The shape of the extension 320 can be adjusted by bending to adjust the shooting position of the camera module 310. Bending refers to the process of applying a bending moment to the extension 320, causing it to bend and deform in a specific direction. The bending operation is based on the bending theory of beams. When a bending moment is applied to the extension 320, a bending stress distribution will be generated on the cross-section of the extension 320, with tensile stress on the tension side and compressive stress on the compression side. When the bending stress exceeds the yield strength of the material, the extension 320 undergoes plastic bending deformation.

[0070] Bending operations can be performed manually, with tool assistance, or using a dedicated bending device. Manual bending involves the user applying bending force directly by hand to adjust the shape of the extension 320. This method is simple and intuitive, suitable for extensions with small cross-sectional dimensions and moderate bending resistance. Tool assistance involves using general-purpose tools such as pliers and wrenches to bend the extension 320. This method provides greater bending torque and is suitable for extensions with larger cross-sectional dimensions or higher material strength. Dedicated bending devices involve using specially designed bending tools to precisely bend the extension 320. This method enables precise angle control and repeatable bending operations.

[0071] The shooting position adjustment of the camera module 310 is achieved through the shape change of the extension member 320. The bending deformation of the extension member 320 directly changes the spatial positional relationship between the camera module 310 and the connecting base 330. The bending of the extension member 320 in the horizontal direction can adjust the left and right shooting angle of the camera module 310, realizing the scanning adjustment of the horizontal field of view. The bending of the extension member 320 in the vertical direction can adjust the up and down shooting angle of the camera module 310, realizing the adjustment of the pitch angle. The three-dimensional bending deformation of the extension member 320 can realize the adjustment of the camera module 310 to any position in three-dimensional space, providing users with maximum shooting flexibility.

[0072] The adjustable flexibility of the extension 320 and the rotating adjustment of the connector 330 complement each other, forming a dual position adjustment mechanism for the camera module 310. The rotating adjustment of the connector 330 provides coarse adjustment for the camera module 310, enabling rapid and wide-range angle adjustments. The adjustable flexibility of the extension 320 provides fine adjustment for the camera module 310, allowing for fine-tuning and customization based on the rotating adjustment of the connector 330. This dual adjustment mechanism enables the camera module 310 to adapt to more complex and diverse shooting needs, improving the flexibility and functional adaptability of the wearable device 10.

[0073] The malleable structural design of the extension component 320 also provides shock absorption and cushioning. When the wearable device 10 is subjected to external impact or vibration during use, the extension component 320 can absorb impact energy through slight elastic-plastic deformation, protecting the camera module 310 from damage. The deformation recovery characteristics of the extension component 320 allow it to return to its original shape after being subjected to slight external force, ensuring the stability of the shooting position of the camera module 310. The malleable adjustment function of the extension component 320 provides users with personalized shooting position customization capabilities. Users can personalize the extension component 320 according to their own usage habits and shooting preferences to create a customized shooting configuration.

[0074] Specifically, the extension 320 includes a shaped part and a flexible layer. The shaped part is connected to the camera module 310 and the connector 330 respectively, and the flexible layer covers the outside of the shaped part.

[0075] The molding section, as the core support structure of the extension 320, is responsible for transmitting the weight load of the camera module 310 and maintaining its shape stability. The connection between the molding section and the camera module 310 is achieved through mechanical fastening, using threaded connections, snap-fit ​​connections, or welding to ensure a reliable structural connection. Threaded connections provide a detachable connection, facilitating maintenance and replacement of the camera module 310. Snap-fit ​​connections enable quick assembly and disassembly, improving assembly efficiency and ease of use. Welded connections offer the highest connection strength and sealing performance, suitable for applications requiring extremely high structural stability.

[0076] The connection between the molded part and the connector 330 also employs a reliable mechanical connection method, ensuring that the molded part can effectively transfer various loads generated by the camera module 310 to the connector 330. The design of the connection area needs to consider stress concentration, reducing the degree of stress concentration by increasing the connection area, using transition fillets, or employing a gradient cross-section design. The length of the molded part can be determined based on the installation position requirements of the camera module 310 and the shooting field of view requirements; no single limitation is imposed here.

[0077] A flexible layer covers the outside of the molded part, providing comprehensive protection and surface treatment. Reliable connections are achieved between the flexible layer and the molded part through bonding, hot pressing, or mechanical encapsulation. Bonding uses adhesives to form chemical bonds or physical adsorption between the flexible layer and the molded part, providing excellent adhesive strength and sealing performance. Hot pressing uses heat and pressure to plastically deform the flexible layer material and tightly adhere it to the surface of the molded part, enabling glue-free bonding and environmentally friendly processing. Mechanical encapsulation utilizes the elastic deformation of the flexible layer material to achieve a tight wrapping of the molded part, providing removable protection and reusability.

[0078] The addition of a flexible layer enhances wearing comfort. Based on ergonomic design principles, this layer improves the user experience by providing a soft contact surface and cushioning protection. Materials for the flexible layer can include silicone, polyurethane, thermoplastic elastomers, or fabrics, all possessing good softness and skin compatibility. Silicone offers high softness, strong aging resistance, and easy cleaning, providing long-term, stable comfort and protection. Polyurethane boasts good elasticity, wear resistance, and strong resilience, maintaining excellent performance stability during repeated deformation. Thermoplastic elastomers offer good processability, strong environmental performance, and recyclability, aligning with green design principles. Fabrics offer good breathability, a comfortable feel, and moisture-wicking properties, making them suitable for extended wear.

[0079] In one embodiment, the wearing structure 100 includes a connecting frame 110, a wearing frame 120, and a main unit housing 130. The connecting frame 110 has a ring structure, and the wearing frame 120 is formed with a space for accommodating the ear. An audio module is connected to the wearing frame 120. The wearable device 10 also includes a main unit module, which is disposed inside the main unit housing 130 and is signal-connected to the audio module and the camera module 300, respectively.

[0080] The wearing structure 100 serves as the main support frame of the wearable device 10, undertaking the important functions of fixing the various functional modules and ensuring wearing stability. The connecting frame 110, the wearing frame 120, and the main body shell 130 are mechanically connected to form a complete wearing structure 100, providing stable structural support for the wearable device 10.

[0081] The connecting frame 110 is a ring-shaped structure that provides the main structural support and wearing fixation function for the wearable device 10. The ring-shaped design is based on the geometry of the human head, ensuring a good fit and stable wearing effect. The ring-shaped design of the connecting frame 110 allows the weight of the wearable device 10 to be evenly distributed across multiple contact points on the user's head, avoiding discomfort caused by excessive local pressure. The connecting frame 110 can be made of materials with a good strength-to-weight ratio, such as aluminum alloy, titanium alloy, carbon fiber composite material, or high-strength engineering plastics. Aluminum alloy has the advantages of being lightweight, high-strength, and corrosion-resistant, effectively controlling the overall weight of the wearable device 10 while ensuring structural strength. Titanium alloy has the advantages of high strength, strong corrosion resistance, and good biocompatibility, making it suitable for long-term wear and high-end applications. Carbon fiber composite material has the advantages of being extremely lightweight, extremely strong, and highly flexible in design, enabling optimal strength-to-weight ratio and personalized appearance design.

[0082] The connecting frame 110 can be an arc-shaped structure that wraps around the back of the user's head. This arc-shaped design better adapts to the natural curve of the human head, improving wearing comfort and stability. The radius of curvature of the connecting frame 110 can be optimized based on ergonomic data to ensure good fit for users with different head shapes. The design of the connecting frame 110 wrapping around the back of the user's head avoids obstructing the user's facial vision, ensuring that the wearable device 10 does not affect the user's normal visual activities during use.

[0083] The earpiece 120 is molded with a space to accommodate the ear, providing a suitable mounting position and acoustic transmission path for the audio module. This ear-accommodating space is achieved through a precise molding process, with its shape and dimensions designed according to the anatomical features of the human ear. The earpiece 120 can be molded with an inner surface curve that matches the shape of the human auricle, achieving a comfortable fit. The earpiece 120 can be made of materials with good flexibility and skin compatibility, such as silicone, polyurethane, thermoplastic elastomers, or soft PVC. Silicone material has the advantages of high softness, strong aging resistance, and easy cleaning, providing long-term stable wearing comfort. Polyurethane material has the advantages of good elasticity, wear resistance, and strong resilience, maintaining good shape stability during repeated wear.

[0084] The audio module is connected to the wearer 120, achieving a reliable connection through mechanical fixation and electrical connection. The audio module includes components such as a speaker unit, audio processing circuitry, and signal transmission lines. The speaker unit converts electrical signals into sound signals, the audio processing circuitry amplifies, filters, and equalizes the audio signals, and the signal transmission lines transmit the audio signals from the host module to the audio module. The audio module can be connected to the wearer 120 using screw fixing, snap-fit ​​connection, or adhesive fixing. Screw fixing provides a detachable connection, facilitating maintenance and replacement of the audio module. Snap-fit ​​connection allows for quick assembly and disassembly, improving production efficiency and user convenience.

[0085] The main unit housing 130 is used to house the main unit module, providing mechanical protection and environmental sealing. The internal space of the main unit housing 130 is designed according to the external dimensions and heat dissipation requirements of the main unit module, ensuring that the main unit module can be stably installed and operate normally inside the main unit housing 130.

[0086] The main unit module is housed within the main unit casing 130. The main unit module includes a main controller, memory, communication module, power management module, and various electronic components such as sensors. The main controller is responsible for the functional control and data processing of the entire wearable device 10. The memory stores system programs and user data. The communication module communicates with external devices. The power management module manages battery power and controls the power supply to each module. Auxiliary components such as shock-absorbing pads, heat sinks, or thermally conductive materials can be installed between the main unit module and the main unit casing 130 to improve the operational stability and lifespan of the main unit module.

[0087] The host module is connected to both the audio module and the camera module 300 via cables, flexible circuit boards, or wireless communication. Cable connections provide stable signal transmission and high bandwidth, suitable for high-quality audio and video signal transmission. Flexible circuit board connections offer good mechanical flexibility while maintaining signal transmission quality, adapting to the moving parts of the wearable device 10. Wireless communication connections avoid the constraints of physical cables, improving the design flexibility and user convenience of the wearable device 10. The signal connection between the host module and the audio module includes the transmission of audio, control, and power signals; the signal connection between the host module and the camera module 300 includes the transmission of video, control, and power signals.

[0088] In a preferred embodiment, the main housing 130 is located between the wearing frame 120 and the connecting frame 110. This location optimizes the weight balance and improves the structural compactness of the wearable device 10. The position of the main housing 130 is chosen based on ergonomic principles and weight distribution optimization theory, allowing the main housing 130 to fully utilize the space between the wearing frame 120 and the connecting frame 110, forming a compact overall structural layout.

[0089] The design of the main unit housing 130, located between the wearing frame 120 and the connecting frame 110, allows the weight of the main unit module to be effectively transferred to the user's head through the connecting frame 110, avoiding excessive local pressure caused by the weight being concentrated on a single support point. The shape of the main unit housing 130 can be customized according to the spatial contour between the wearing frame 120 and the connecting frame 110, maximizing the use of available space while maintaining a good overall appearance.

[0090] At this point, the center of gravity of the camera module 300 and the main unit housing 130 are located on either side of the ear, resulting in good balance. This weight distribution design is based on the principle of mechanical balance, achieving a balanced center of gravity and optimized wearing stability of the wearable device 10 by distributing the main weight components to the front and back of the user's head. The camera module 300 is connected to one side of the wearable device 10 via the extension 320, and its center of gravity creates a certain torque relative to the user's ear. The main unit housing 130 is located on the other side of the user's ear, and its weight generates a torque in the opposite direction, balancing the torque generated by the camera module 300. This symmetrical weight distribution design effectively reduces the net torque generated by the wearable device 10 on the user's head, preventing the wearable device 10 from tilting or slipping during use.

[0091] The center of gravity of the camera module 300 can be optimized by adjusting the layout of its internal components. The weight distribution of components such as the lens assembly, image sensor, and processing circuitry within the camera module 300 directly affects its center of gravity. By rationally arranging the positions of heavy components, the center of gravity of the camera module 300 can be brought as close as possible to the connection point of the extension 320, reducing the bending moment load borne by the extension 320. Similarly, the weight distribution of the main unit module within the main housing 130 can be adjusted by optimizing the layout of its internal components, achieving an optimal balance between the center of gravity of the main housing 130 and the camera module 300.

[0092] Wearable device 10 can be an ear-hook type of earphone. As a specific implementation of the ear-hook type of earphone, wearable device 10 adopts an ear-hook wearing method, achieving stable wearing by hooking it onto the user's ear via a wearing bracket 120. The design of ear-hook earphones has the technical advantages of being easy to wear, not obstructing the ear canal, and providing high comfort. The ear-hook portion of the wearing bracket 120 is designed according to the anatomical characteristics of the human auricle, forming a good fit with the outer contour of the user's ear. The ear-hook portion is made of a flexible material with a certain degree of elastic deformation, capable of adapting to the differences in ear shape among different users.

[0093] Earhook headphones can employ an open-back speaker design for their audio modules. This design doesn't completely seal off the user's ear canal, allowing ambient sounds to enter the ear simultaneously with the audio playback. This design enables users to maintain awareness of their surroundings while enjoying audio content, improving safety. The acoustic design of open-back speakers needs to consider sound leakage control and sound quality optimization, achieving good audio playback and privacy protection through acoustic modeling and optimized design.

[0094] Wearable device 10 may be a bone conduction headphone. As a specific implementation of a bone conduction headphone, wearable device 10 uses bone conduction technology to achieve audio playback. The audio module includes a bone conduction transducer and a vibration transmission component. The bone conduction transducer is responsible for converting electrical signals into mechanical vibrations, and the vibration transmission component is responsible for effectively transmitting the mechanical vibrations to the user's skull. Bone conduction technology achieves sound perception by directly stimulating the inner ear through skull vibrations, without completely obstructing the user's ear canal. It has the technical advantages of comfortable wear, strong environmental awareness, and no hearing damage even after prolonged use.
