[0025] The following is combined Figures 1 to 12 This application describes a smart ring according to embodiments thereof and a smart home interaction system based on the smart ring.

[0026] like Figures 1 to 9 As shown, according to some embodiments of this application, a smart ring is provided, including an annular shell 1, a miniature camera module 2, an interaction component 3, and a control module 4; the annular shell 1 has a receiving cavity formed inside, and the outer ring of the annular shell 1 is provided with a first through hole 111 and a second through hole 112 communicating with the receiving cavity; the miniature camera module 2 is disposed in the receiving cavity, and the lens of the miniature camera module 2 is exposed through the first through hole 111, and the miniature camera module 2 is used to acquire image information of an external device 6; the interaction component 3 includes an activation module and a communication module, the interaction component 3 is disposed in the receiving cavity, and at least a part of the structure of the activation module is exposed through the second through hole 112, and the communication module is used to perform data interaction with the external device 6; the control module 4 is disposed in the receiving cavity, and the control module 4 is electrically connected to the miniature camera module 2, the activation module, and the communication module respectively, and can control the working state of the miniature camera module 2 and the communication module respectively by acquiring the activation signal of the activation module.

[0027] Specifically, in this embodiment, the smart ring uses a ring-shaped shell 1 as its core carrier. The ring-shaped shell 1 has an internal cavity. The outer ring of the ring-shaped shell 1 has a first through-hole 111 and a second through-hole 112, which are connected to the cavity, providing suitable installation and working space for each functional module. The miniature camera module 2, the interaction component 3, and the control module 4 are all integrated within the cavity, achieving a compact overall design. The lens of the miniature camera module 2 is exposed through the first through-hole 111, ensuring unobstructed image acquisition. At least part of the activation module of the interaction component 3 extends from the second through-hole 112, meeting the user's external operation needs. The communication module is built into the cavity. The control module 4 is also integrated into the cavity and electrically connected to the other modules. The layout of each component conforms to the shape of the ring-shaped shell 1, balancing structural integration with the implementation conditions of each function, thus adapting to the miniaturization and portability of the ring.

[0028] In the above structure, the miniature camera module 2 can be a customized miniature camera 21 based on CMOS, which can meet the image or video acquisition requirements according to specific focal length and FOV requirements. In the interaction component 3, the activation module can adopt a capacitive touch sensing module or a light-touch metal spring switch, with part of the exposed structure attached to the ring shell. When the user touches or presses, the activation signal is triggered and transmitted to the control module 4. The communication module can be an NFC near-field communication module or a Bluetooth module. When running, it responds to the instructions of the control module 4 and establishes a temporary or long-term connection with the external device 6 through wireless signals to realize bidirectional transmission of instructions and data. The control module 4 can be a micro microcontroller with built-in control algorithms and storage units. When running, after receiving the activation signal, it accurately controls the start and stop of the miniature camera module 2 and the connection with the communication module. At the same time, it analyzes image information and matches the parameters of the external device 6 to ensure that all modules operate in a coordinated and efficient manner, adapting to the portable use requirements of the smart ring.

[0029] The smart ring provided in this application uses the control module 4 as its core, with each functional module connected electrically to form a collaborative whole. The triggering method is based on the exposed activation module. That is, when the user operates the activation module, the activation module transmits an activation signal to the control module 4. After receiving the signal, the control module 4 first triggers the miniature camera module 2 to enter the working state. The miniature camera module 2 acquires image information from the external device 6 through the exposed lens and feeds it back to the control module 4. After the control module 4 recognizes or processes the image information, it sends a working command to the communication module, driving the communication module to establish data interaction with the external device 6 (such as establishing a wireless connection). This completes the entire process of autonomous control from signal triggering, image acquisition to device connection, without the need for other external media, realizing direct linkage between the smart ring and the external device 6.

[0030] In the aforementioned structure, by highly integrating the miniature camera module 2, the interaction component 3, and the control module 4 into the ring-shaped housing 1, direct interaction between the smart ring and the external device 6 is achieved. This significantly simplifies the interaction steps between devices, eliminating the intermediate steps of pairing with a smartphone and operating via an app, thus improving the convenience and efficiency of the interaction. Simultaneously, the integrated layout of each functional module conforms to the shape and characteristics of the ring, preserving the inherent advantages of the smart ring—comfortable to wear all day, highly discreet, and fashionable—without altering its original user experience. Furthermore, this design is adaptable to multiple scenarios such as health monitoring and mobile payment. Especially in smart home human-computer interaction scenarios, it significantly optimizes the operating experience, expands the practical application value of the smart ring, and enhances the product's market competitiveness.

[0031] Optionally, such as Figures 3 to 5 As shown, the control module 4 includes a circuit board 41 and a battery module 44. The circuit board 41 is fixed to the inner wall of the annular housing 1 and is connected to the battery module 44 in a ring.

[0032] Specifically, in this embodiment, the control module 4 adopts a combined structure of circuit board 41 and battery module 44, adapted to the shape and spatial characteristics of the smart ring's annular housing 1. The circuit board 41 is a rigid-flex board adapted to the ring size, and can be tightly attached to the inner wall of the annular housing 1 using snap-fit ​​or adhesive methods, fully utilizing the inner cavity of the housing to satisfy the electrical connection relationships between different modules arranged along the annular housing 1 and the control module 4. Furthermore, the battery module 44 can be a flexible battery, arranged in a ring connection with the circuit board 41. The two form an integrated annular structure along the inner contour of the housing, ensuring a stable physical connection and circuit conduction between the circuit board 41 and the battery module 44, while also allowing the control module 4 to fit perfectly within the annular housing 1, achieving a compact and miniaturized structure. Additionally, a charging module 42 can be connected to the circuit board 41, with its charging interface exposed from the inner ring of the annular housing to charge the battery module 44.

[0033] In the above structure, the ring-shaped connection structure 222 between the circuit board 41 and the battery module 44 maximizes the use of the limited internal space of the ring-shaped shell 1, realizing the miniaturization and integration of the control module 4. This complements the layout of the miniature camera module 2 and the interaction component 3, ensuring the overall compact form of the smart ring and its comfortable and fashionable fit. Simultaneously, the wall-mounted fixing of the circuit board 41 and its ring-shaped connection with the battery module 44 shortens the power and signal transmission path, reduces transmission loss, and improves the stability of power supply and the efficiency of signal transmission. The control module 4 provides reliable hardware support for precisely controlling the miniature camera module 2 and the interaction component 3, ensuring the coordinated operation of all functional modules and further enhancing the overall working stability and response speed of the smart ring.

[0034] Optionally, such as Figures 1 to 5 As shown, the miniature camera module 2 includes a camera 21 and a camera bracket 22. The camera 21 is mounted on the camera bracket 22 and electrically connected to the circuit board 41. The camera bracket 22 is fixed on the circuit board 41 and / or inside the annular housing 1 so that the lens of the camera 21 can be exposed through the first through hole 111. Specifically, in this embodiment, the camera bracket 22 provides a stable mounting carrier for the camera 21. It can be fixed within the circuit board 41 and / or the annular housing 1, accurately positioning the camera 21 and ensuring that the camera lens is precisely and unobstructedly exposed through the first through-hole 111. This guarantees the effectiveness and accuracy of image information acquisition by the external device 6, providing a foundation for subsequent image recognition processes, such as... Figure 6 As shown, the camera bracket 22 is simultaneously welded or glued to both the annular housing 1 and the circuit board 41. Meanwhile, after being assembled via the camera bracket 22, the camera 21 achieves a stable electrical connection with the circuit board 41, ensuring smooth transmission of image information. The fixing structure of the camera bracket 22 is adapted to the spatial characteristics of the annular housing 1, without occupying excessive additional cavity space. It balances the functionality of the miniature camera module 2 with the overall compact structure of the smart ring, and also reduces the impact of displacement and vibration on the camera 21 during wear, thus improving the operational stability of the miniature camera module 2.

[0035] Optionally, such as Figures 5 to 9 As shown, the camera bracket 22 has a groove structure 221 and a connecting structure 222 located around the groove structure 221. The camera bracket 22 is fixed to the annular housing 1 through the connecting structure 222. The camera 21 is assembled in the groove structure 221, and at least part of the groove structure 221 is assembled at the first through hole 111. The lens of the camera 21 is exposed from the first through hole 111.

[0036] Specifically, in this embodiment, the camera bracket 22 adopts a design combining a groove structure 221 and a connecting structure 222, allowing the camera 21 to be fixedly installed inside the groove structure 221. The groove structure 221 is fixed to the annular housing 1 through the connecting structure 222, thereby positioning the lens of the camera 21 at the position of the first through hole 111, facilitating the assembly and positioning of the camera 21. The outer end of the groove structure 221 (i.e., the end exposed in the annular housing) may be provided with a through hole matching the lens of the camera 21, so that the groove structure 221 can both protect the camera 21 and prevent obstruction of the lens.

[0037] Optionally, such as Figure 8As shown, the inner wall of the groove structure 221 is provided with multiple positioning ribs 223, and the outer contour of the groove structure 221 matches the shape of the first through hole 111. The camera 21 is positioned and assembled in the groove structure 221 by the positioning ribs 223. The groove structure 221, together with the multiple positioning ribs 223 on its inner wall, can form a stable and precise assembly constraint on the camera 21, effectively preventing the camera 21 from shaking, shifting, or rotating within the groove structure 221, ensuring that the lens attitude and position remain stable. The positioning ribs 223 can extend along the inner to outer ring of the annular shell 1 to provide guidance for the assembly of the camera 21 and improve assembly efficiency.

[0038] Optionally, such as Figure 7 and Figure 9 As shown, the first through hole 111 is square, and the outer contour of the first end of the groove structure 221 matches the shape of the first through hole 111 to be positioned within the first through hole 111. The second end of the groove structure 221 is fixed to the circuit board 41. The shape of the connecting structure 222 matches the shape of the annular shell 1 to be fixed within the annular shell 1, as shown. Figure 6 and Figure 7 As shown.

[0039] Specifically, in the above structure, the outer contour of the groove structure 221 matches the shape of the first through hole 111, and both can be set to square, so that the first end of the groove structure 221 can be directly assembled into the first through hole 111, realizing the precise alignment of the camera 21 and the through hole of the housing, ensuring that the lens is exposed normally without obstruction or misalignment, and greatly improving the consistency and reliability of image acquisition. The shape of the connecting structure 222 is contoured to the shape of the annular housing 1, so as to facilitate fixing on the annular housing 1, providing a flexible and reliable installation method, enhancing the overall structural strength and vibration resistance, and reducing the impact of impact and vibration on the camera 21 during wear.

[0040] Optionally, such as Figures 1 to 2 ,as well as Figures 10 to 11 As shown, the activation module includes a push-button switch 31. When the push-button switch 31 is pressed by an external force, it outputs a feedback signal. The control module 4 can control the working state of the miniature camera module 2 according to the feedback signal of the push-button switch 31.

[0041] Specifically, in this embodiment, by setting the activation module as a push-button switch 31 and electrically connecting it to the control module 4, the push-button switch 31 can output a feedback signal when pressed by an external force, forming a simple and reliable trigger control structure. The push-button switch 31 can directly send a stable feedback signal to the control module 4, and the control module 4 can accurately start and stop the miniature camera module 2 based on this signal, achieving rapid response to interactive commands and effectively simplifying the trigger logic and operation process of the smart ring.

[0042] The triggering mechanism of the button switch 31 eliminates the need for complex sensing or multi-step operations. Users can activate the image acquisition function with a simple button press, lowering the barrier to entry and enhancing ease of interaction. Simultaneously, the button switch 31 features a compact structure, high stability, and fits the compact installation space of the ring. Its reliable assembly and outstanding anti-interference capabilities prevent accidental triggering, ensuring accurate and controllable switching of the miniature camera module 2's operating state. This provides a stable and efficient triggering foundation for direct interaction between the smart ring and external devices 6, improving overall reliability and user experience.

[0043] Optionally, such as Figures 3 to 5 As shown, the interactive component 3 also includes a vibration module 32, which is electrically connected to the control module 4 and contacts the inner ring of the annular housing 1, and is used to provide feedback on the interaction status between the communication module and external devices.

[0044] Specifically, in this embodiment, by adding a vibration module 32 to the interaction component 3, such as using a vibration motor to achieve tactile feedback, the interactive experience and status indication capabilities of the smart ring are effectively improved. The vibration module 32 is electrically connected to the control module 4 and arranged close to the inner ring of the annular shell 1, allowing vibration to be directly transmitted to the wearing area. For example, the control module 4 autonomously controls the start / stop and vibration mode of the vibration module 32 according to the real-time working status of the communication module. When the communication module successfully connects to, disconnects from, or exchanges data with the external device 6, the vibration motor outputs corresponding feedback, allowing the user to perceive the connection status without having to check, thus enhancing the sense of confirmation during operation.

[0045] The structure features rapid vibration feedback response and strong anti-interference capabilities, which simplifies user operation and judgment, enhances interaction reliability, and provides intuitive and efficient status prompts for direct interaction between the smart ring and external devices, thereby improving overall ease of use and user experience.

[0046] Optionally, such as Figures 3 to 5 As shown, the interactive component 3 also includes an inertial measurement unit, which is electrically connected to the control module 4 and is used to identify the motion state of the smart ring. The control module 4 can output command signals based on the feedback signals from the inertial measurement unit. Specifically, in this embodiment, by adding an inertial measurement unit to the interaction component 3, contactless intelligent interaction based on gestures can be realized, expanding the control methods and application scenarios of the smart ring. The inertial measurement unit can use miniature devices such as a six-axis accelerometer, gyroscope, or nine-axis attitude sensor, which can collect the wearer's gestures, posture changes, and motion information in real time, and transmit the corresponding feedback signals to the control module 4.

[0047] After analyzing and recognizing the signal, control module 4 directly outputs the corresponding command signal, enabling operation without the need for buttons or image triggers, significantly improving the freedom and convenience of interaction. This module is compact, low-power, and fits the compact structure of a ring, enabling gesture control such as sliding, flipping, tapping, and air tapping. It is suitable for smart home and quick operation scenarios, further simplifying interaction steps and enhancing the product's intelligence and flexibility.

[0048] Optionally, such as Figures 1 to 5 As shown, the interactive component 3 also includes a monitoring module, which is electrically connected to the control module 4 and contacts the inner wall of the annular housing 1. The monitoring module is used to monitor the user's physiological parameters.

[0049] Specifically, in this embodiment, by adding a monitoring module to the interactive component 3, the smart ring can perform health monitoring functions while enabling device interaction, thus expanding the product's application scenarios. The monitoring module is in close contact with the inner wall of the annular shell 1, and can stably collect the user's physiological signals. Common types include heart rate sensors, blood oxygen sensors, body temperature sensors, skin conductance sensors, and sleep monitoring sensors. The module is electrically connected to the control module 4, enabling real-time transmission of the collected physiological parameters to the control module 4 for real-time data processing and recording.

[0050] The smart ring provided in this application has a high degree of fit and can be worn all day long. Without increasing the extra size or affecting the compactness of the structure, it can continuously monitor health data, improve the practicality and functionality of the product, and take into account human-computer interaction and health management, so as to provide users with a more comprehensive and convenient integrated smart wearable experience.

[0051] Optionally, such as Figures 1 to 5 As shown, the control module 4 also includes a charging module 42 and a battery module 44. The charging module 42 is electrically connected to the battery module 44. The charging port of the charging module 42 is exposed in the inner ring of the annular housing 1 to facilitate the connection of the charging cable.

[0052] Optionally, such as Figures 3 to 5 As shown, the monitoring module includes an optical sensor 33 and a temperature sensor 34. The optical sensor 33 and temperature sensor 34 are arranged sequentially and at intervals along the inner ring of the annular housing 1, and are used to monitor different physiological parameters of the user. For example, the optical sensor 33 uses a PPG optical sensor to monitor the user's heart rate or blood oxygen, while the temperature sensor 34 can monitor the user's skin temperature for predicting ovulation, etc. By arranging the sensors sequentially and at intervals within the annular housing and contacting the inner ring of the annular housing 1, each sensor can be placed either through the inner ring or directly against the user's skin, improving the accuracy and reliability of the monitoring.

[0053] Optionally, such as Figures 1 to 5As shown, the annular housing 1 includes an outer ring housing 11 and an inner ring housing 12 that are sealed together. The first through hole 111 and the second through hole 112 are both located on the outer ring housing 11.

[0054] Specifically, in this embodiment, the annular housing 1 structure, in which the outer housing 11 and the inner housing 12 are sealed and fastened together, effectively improves the overall sealing performance and structural stability of the smart ring, while facilitating the assembly and maintenance of the internal modules. Both the first through hole 111 and the second through hole 112 are located on the outer housing 11, ensuring the normal exposed operation of the miniature camera module 2 lens and the activation module without compromising the integrity and fit of the inner housing 12. The sealed and fastened structure prevents dust and moisture from entering the internal cavity, protecting the circuit board 41, battery, and various sensors, ensuring stable operation, and extending their service life.

[0055] Optionally, such as Figures 1 to 5 As shown, the outer shell 11 is a metal shell, and the inner shell 12 is a potting compound.

[0056] Specifically, in this embodiment, the outer ring shell 11 is a metal shell, and the inner ring shell 12 adopts a potting compound structure, which combines structural strength, aesthetic appeal, and internal protection. The metal outer ring shell 11 has high structural rigidity, wear resistance, and deformation resistance, which can effectively protect the internal components, while enhancing the product's aesthetic appeal and fashion attributes, making it suitable for the wearing scenarios of smart rings.

[0057] The inner potting compound possesses excellent sealing, cushioning, and conformability, fully filling internal gaps to achieve complete encapsulation and protection for components such as the circuit board 41, sensor, and miniature camera module 2, enhancing waterproof, dustproof, and vibration-resistant performance. The potting compound provides a soft contact with the wearing area, improving comfort and avoiding the coldness and discomfort associated with direct metal contact. The combination of inner and outer materials ensures overall structural stability while optimizing internal heat dissipation and structural cushioning, balancing appearance, strength, sealing, and wearing experience to improve product reliability and practicality. The circuit board 41 is designed as a rigid-flex board, connected to the battery and shaped into a ring for easy encapsulation using the potting compound.

[0058] According to the second aspect of this application, reference to Figures 10 to 12 A smart home interaction system based on the smart ring provided in the first aspect is provided, comprising: when the smart ring receives an activation signal from an activation module, controlling a miniature camera module 2 to acquire image information of smart devices in the smart home environment; the smart ring controls a communication module to establish a communication connection with at least one smart device in the smart home based on the image information; the smart ring identifies user commands by monitoring the user's hand posture and sends the user commands to the smart device through the established communication connection.

[0059] In this embodiment, when the user operates the activation module, the activation module transmits an activation signal to the control module 4. After receiving the signal, the control module 4 first triggers the miniature camera module 2 to enter the working state. The miniature camera module 2 acquires image information of each smart device 6 in the home environment through the exposed lens and feeds it back to the control module 4. After the control module 4 recognizes or processes the image information, it sends a working command to the communication module to drive the communication module to establish a communication connection with the external device 6 (such as establishing a wireless connection). This completes the entire process of autonomous control from signal triggering, image acquisition to device connection, without the need for other external media, and realizes direct linkage between the smart ring and smart devices in the smart home.

[0060] Optionally, refer to Figure 12 Before establishing a communication connection, it also includes: the field of view of the miniature camera module 2 in the mobile smart ring, so that the corresponding area of ​​the field of view covers the currently paired smart device.

[0061] The above-mentioned smart ring can be used in smart homes as follows: The ring is worn on the index finger 51, with the miniature camera module 2 facing the back of the hand to facilitate the camera 21's orientation for device recognition; the button switch 31 faces the thumb 52 to facilitate the thumb's pressing function, and the hand 5's posture is as follows: Figure 10 As shown.

[0062] When interaction with smart home devices is required, the smart ring's camera 21 is pointed at the corresponding smart device, even if the field of view (FOV) of the miniature camera module 2 covers the area where the smart device is located, such as... Figure 12 As shown, pressing the button switch 31 with thumb 52 triggers the corresponding image recognition algorithm. Once the algorithm completes, the ring vibrates via a vibration motor to provide feedback, indicating that the device is connected. Then, the smart device can be controlled via built-in gesture algorithms (swiping, flipping, etc.). Figure 11 As shown.

[0063] When you need to switch control devices, simply point the smart ring's camera 21 at the new device and repeat the above steps.
