[0001] This invention relates to the field of smart wearable device technology, and in particular to a smart ring and its usage method. Background Technology

[0002] With the continuous development of smart wearable device technology, smart rings have gradually integrated image acquisition functions. However, due to the small size of smart rings, the capacity of their internal batteries is often limited.

Summary of the Invention

[0003] The main objective of this invention is to propose a smart ring and its usage method, aiming to solve the problems of high power consumption and short battery life of existing smart rings due to the image acquisition module.

[0007] In one embodiment, the smart ring further includes a flexible circuit board, the flexible circuit board comprising: A first plate is disposed in the cavity and electrically connected to the image acquisition module; The second plate is disposed on the side of the outer cover near the inner ring and is electrically connected to the distance measuring unit, the light sensing unit, and the trigger module; and A bendable plate, one end of which extends into the cavity to connect with the first plate and the other end of which extends into the second plate, the bendable plate being configured to deform with the relative sliding of the outer cover to maintain the electrical connection between the first plate and the second plate.

[0008] In one embodiment, the ring body further includes a limiting structure, which includes a groove and a sliding shaft. One of the groove and the sliding shaft is disposed on the outer peripheral wall of the inner ring body, and the other is disposed on the side of the outer cover body near the inner ring body. The groove extends along the sliding direction of the outer cover body. The sliding shaft slides in conjunction with the groove, and the two end walls of the groove abut against the sliding shaft to define the stacking position and the staggered position.

[0009] In one embodiment, the smart ring further includes: A thermoelectric power generation module is disposed within the cavity. The module includes an input semiconductor and an output semiconductor. The input semiconductor is located near the inner ring wall of the cavity; the output semiconductor is located on the outer ring wall of the cavity and is adapted to the shape of the ring body. A boost module, which is housed in the cavity and connected to the output semiconductor, and is used to charge the battery.

[0010] In one embodiment, a through hole is formed in the outer peripheral wall of the ring body; the smart ring further includes a heat-conducting structure, the heat-conducting structure comprising: A heat sink is located outside the through hole and blocks the through hole; A heat-conducting component, comprising a heat-conducting pillar and two heat-conducting sleeves, wherein one end of the heat-conducting pillar is connected to the two heat-conducting sleeves located within the cavity, and the other end of the heat-conducting pillar passes through the through hole to connect to the heat sink; the two heat-conducting sleeves respectively enclose the image acquisition module and the output semiconductor; and A sealing element, which fills the space between the heat-conducting column and the through hole.

[0011] In one embodiment, the trigger module includes two buttons, which are spaced apart circumferentially along the body of the ring. The two buttons are configured such that at least one button can generate a first control signal and a second control signal according to user operation, and control the distance measuring unit and the light sensing unit to perform detection work according to the first control signal, and control the image acquisition module to perform shooting work according to the second control signal.

[0012] In one embodiment, the button includes: A touch body, disposed within the cavity and movable in the pressing direction, with at least a portion of the touch body exposed outside the ring body, is used to sense changes in light caused by the user's finger moving on the touch body and to generate a first control signal; and An elastic wave component is disposed in the cavity and connected to the side of the touch body facing the center of the ring body.

[0014] The smart ring with image acquisition function provided by this invention solves the problems of high power consumption and short battery life of existing smart rings due to the collaborative work of the environmental perception module and the image acquisition module. Specifically, the smart ring includes a ring body worn on the finger, which integrates an environmental perception module and an image acquisition module. The environmental perception module is further divided into a distance measurement unit and a light sensing unit. First, the distance measurement unit measures the distance between the target and the ring body in advance and pre-calculates the focal length parameters. Then, the light sensing unit measures the ambient light intensity in advance and pre-calculates the exposure parameters. Finally, the image acquisition module directly completes the image acquisition of the target based on the pre-calculated focal length parameters and exposure parameters, without the need for the image acquisition module to perform additional calculations and adaptation parameters. In this way, the environmental perception module pre-calculates the focal length and exposure parameters, eliminating the need for the image acquisition module to perform parameter calculations simultaneously during image acquisition. This significantly reduces the workload of the image acquisition module and effectively lowers its power consumption. By controlling the overall power consumption of the device from the core power-consuming module, the pre-calculation of focal length and exposure parameters allows the image acquisition module to quickly complete image acquisition, shortening the image acquisition time and further reducing the device's power consumption. This effectively extends the smart ring's battery life and improves the user experience. Furthermore, the distance measurement unit and light sensing unit specifically calculate the core shooting parameters, ensuring parameter adaptability and the image quality of the acquired images while avoiding the additional power consumption caused by redundant calculations, achieving a balance between low power consumption and high-quality imaging.

[0021] This invention provides a smart ring 100.

[0022] Please see Figure 1 In one embodiment of the present invention, the smart ring 100 includes: Ring body 1, which is configured to be worn on the user's finger; An environmental sensing module 2, located on the ring body 1, includes a distance measurement unit 21 and a light sensing unit 22. The distance measurement unit 21 is configured to measure the distance between the target object and the ring body 1 and pre-calculate focal length parameters; the light sensing unit 22 is configured to measure ambient light intensity and pre-calculate exposure parameters; and... Image acquisition module 3 is located on the ring body 1; image acquisition module 3 is configured to acquire images of the target based on pre-calculated focal length parameters and exposure parameters.

[0023] It should be noted that the ring body 1, as the basic supporting structure of the smart ring 100, can be made of lightweight, wear-resistant materials suitable for various wearing scenarios. The whole structure is a closed loop, which can be stably worn on the user's finger, providing a solid and reliable installation base and operating carrier for various functional modules. Its structural design fits the shape of the finger, ensuring wearing comfort while also providing sufficient protection for the internal circuits and external modules, avoiding damage from bumps and knocks during daily wear. At the same time, it can rely on its own structure to realize the circuit connection between various modules, ensuring stable data transmission and power supply for each module.

[0024] The environmental sensing module 2 is integrated into the ring body 1 and is adapted to the structure of the ring body 1. It can be embedded inside the ring body 1 or placed on the surface of the ring body 1. The overall structure is compact and can form an integrated design with the ring body 1. This module includes two core functional units: a distance measurement unit 21 and a light sensing unit 22. They work together to complete the parameter pre-calculation work in the early stage of shooting and provide pre-support for subsequent image acquisition. The distance measurement unit 21 and the light sensing unit 22 can be packaged with materials with strong anti-interference to avoid the influence of external environmental factors on measurement accuracy and ensure the accuracy of parameter pre-calculation. At the same time, its operating power consumption is lower than that of the image acquisition module 3, so it will not cause excessive power consumption in the early stage of operation.

[0025] As a core component of the environmental perception module 2, the distance measurement unit 21 can be a miniature infrared ranging chip, combined with a miniature infrared emitting tube and an infrared receiving tube to form a core component. It can adopt a miniaturized structural design adapted to the layout requirements of the ring body 1. It relies on the infrared emitting tube to emit infrared signals, and then the infrared receiving tube to receive the infrared signals reflected by the shooting target, measuring the actual distance between the shooting target and the ring body 1. Based on the measured distance data, it completes the pre-calculation of the focal length parameter. This process is carried out in advance, independently of the image acquisition process of the image acquisition module 3. It can complete the calculation without relying on the image acquisition module 3. Its operating logic is simple and efficient, and it can quickly output the focal length parameter adapted to the current shooting distance, preparing for the subsequent direct call of the image acquisition module 3. At the same time, its structural design conforms to the overall layout of the ring body 1, does not occupy too much extra space, and does not affect the normal wearing and use of the ring.

[0026] The light sensing unit 22 is also integrated into the environmental sensing module 2. It can be a miniature ambient light sensor chip, paired with a photoresistor or photodiode as the core sensing component. It adopts a miniaturized sensing structure and can sense the light intensity of the surrounding environment in real time. Then, it completes the pre-calculation of exposure parameters based on the measured ambient light intensity data. This process is carried out synchronously or sequentially with the parameter pre-calculation of the distance measurement unit 21, and is also completed in advance of the image acquisition process of the image acquisition module 3. There is no need for the image acquisition module 3 to intervene in the calculation. It can output appropriate exposure parameters according to different brightness levels of the environment, ensuring that the exposure effect during subsequent image acquisition is consistent with the actual environment. Its sensing sensitivity is adapted to the range of light intensity changes in daily shooting scenes, and can accurately capture subtle changes in ambient light, ensuring the rationality of the pre-calculation of exposure parameters. At the same time, its operating power consumption is low, consuming only a small amount of power in the process of completing light intensity measurement and parameter pre-calculation.

[0027] The image acquisition module 3 is integrated into the ring body 1. The core can be a miniature CCD image sensor chip, which, together with a miniature lens assembly and a signal processing chip, forms the imaging core. It can adopt a miniaturized imaging structure and can be embedded in the reserved mounting position of the ring body 1 or set to fit the surface of the ring body 1. Its imaging direction can be adjusted to meet the shooting needs when wearing the ring. This module does not need to calculate the focal length and exposure parameters simultaneously during the image acquisition process. Instead, it directly calls the focal length parameters pre-calculated by the distance measurement unit 21 and the exposure parameters pre-calculated by the light sensing unit 22 in the environmental perception module 2. Based on the above two sets of pre-calculated parameters, it directly acquires images of the target. The entire acquisition process does not require additional calculation steps and directly completes imaging based on the pre-set parameters. Its structure is compact and fits the overall layout of the ring body 1. The material can be a scratch-resistant and wear-resistant light-transmitting material to protect the CCD image sensor and miniature lens assembly, avoid external wear on the imaging components, and ensure the clarity of the image acquisition.

[0028] The smart ring 100 with image acquisition function provided by this invention solves the problems of high power consumption and short battery life of existing smart rings 100 by adopting a design in which the environmental perception module 2 and the image acquisition module 3 work together. Specifically, the smart ring 100 includes a ring body 1 worn on the finger, on which the environmental perception module 2 and the image acquisition module 3 are integrated. The environmental perception module 2 is further divided into a distance measurement unit 21 and a light sensing unit 22. First, the distance measurement unit 21 measures the distance between the target and the ring body 1 in advance and pre-calculates the focal length parameters. Then, the light sensing unit 22 measures the ambient light intensity in advance and pre-calculates the exposure parameters. Finally, the image acquisition module 3 directly completes the image acquisition of the target based on the pre-calculated focal length parameters and exposure parameters, without the need for the image acquisition module 3 to perform additional calculations and adaptation parameters. In this way, the environmental perception module 2 pre-calculates the focal length and exposure parameters, so that the image acquisition module 3 does not need to perform parameter calculations simultaneously during image acquisition. This significantly reduces the workload of the image acquisition module 3 and effectively reduces its power consumption. By controlling the overall power consumption of the device from the core power-consuming module, the pre-calculation of focal length and exposure parameters allows the image acquisition module 3 to quickly complete image acquisition, shortening the image acquisition time and further reducing the power consumption of the device. This effectively extends the battery life of the smart ring 100 and improves the user experience. In addition, the distance measurement unit 21 and the light sensing unit 22 specifically calculate the core shooting parameters, which not only ensures parameter adaptability and the image quality of the acquired images, but also avoids the extra power consumption caused by redundant calculations, achieving a balance between low power consumption and high-quality imaging.

[0029] Please see Figure 2 In one embodiment, a cavity is formed inside the ring body 1; the smart ring 100 also includes: Trigger module 4, located on the ring body 1; trigger module 4 is electrically connected to image acquisition module 3 and environmental perception module 2, and is configured to receive user trigger operations and control the operation of distance measurement unit 21, light sensing unit 22, and image acquisition module 3; and The battery is located in the cavity and is used to power the distance measurement unit 21, the light sensing unit 22, the image acquisition module 3 and the trigger module 4.

[0030] It should be noted that the cavity formed inside the ring body 1 is a closed cavity structure. The shape of the cavity is adapted to the overall molding of the ring body 1. It can be combined with the ring body 1 using one-piece injection molding or inlay molding process. The inner wall of the cavity can be treated with insulating and scratch-resistant material, which can effectively isolate external moisture and dust, and at the same time avoid wear and tear on the internal components. It provides an independent and stable placement space for the internal battery. The cavity is not directly connected to the outside of the ring body 1. Only the power supply interface corresponding to each functional module is reserved. This ensures the airtightness of the internal space and enables a stable electrical connection between the battery and each module, which is suitable for the daily protection needs of wearable devices, without affecting the overall fit and structural stability of the ring body 1.

[0031] The trigger module 4 is located in the ring body 1 and can be embedded in the side wall of the ring body 1 or attached to the surface of the ring body 1. The whole adopts an anti-accidental touch structure design, and the shell can be encapsulated with a wear-resistant and sweat-resistant non-metallic material to avoid malfunctions caused by sweat corrosion or friction during daily wear. The trigger module 4 establishes a stable electrical connection with the environmental sensing module 2 and the image acquisition module 3. It integrates a trigger recognition chip and signal transmission components, which can receive various trigger operations such as user pressing, touching or gesture sensing. After receiving the user trigger command, it will first send a start signal to the environmental sensing module 2 to control the distance measurement unit 21 and the light sensing unit 22 to start parameter pre-calculation in sequence. After the parameter pre-calculation is completed, it will send a start signal to the image acquisition module 3 to control the image acquisition module 3 to complete image acquisition based on the pre-calculated parameters. When there is no user trigger operation, the trigger module 4 is in a low-power standby state, only maintaining the basic signal receiving function, and does not send start commands to other modules to ensure that each module does not consume power when not in operation.

[0032] The battery is located in the cavity inside the ring body 1. It can be a soft-pack lithium battery or a button lithium battery. The overall structure is regular and fits the cavity tightly, preventing displacement or abnormal noise caused by shaking during daily wear. The battery shell is wrapped with a high-temperature and corrosion-resistant sealing material, which has good insulation and protection, effectively preventing battery leakage or short circuit and ensuring safety. The battery establishes a unified power supply circuit with the distance measurement unit 21, light sensing unit 22, image acquisition module 3 and trigger module 4 through the power supply interface reserved in the cavity, providing continuous and stable power support for the operation of each module. At the same time, the battery can adapt to a low-power discharge mode, adjusting the power supply according to the working status of each module. The power output is reduced when the module is in standby mode, and the power supply is stable as needed when the module is working, adapting to the power consumption differences of each module.

[0033] In this embodiment, the internal cavity of the ring body 1 provides a dedicated space for the battery. The closed structure combined with the insulation protection design not only ensures the stability of the battery placement but also isolates it from external interference, improving battery safety and lifespan, and preventing battery failure due to external environmental factors, thus providing a basic guarantee for stable device operation. The trigger module 4 achieves linkage control of the environmental sensing module 2 and the image acquisition module 3 through electrical connection. Each module only starts working based on user trigger operation. When there is no trigger, each module is in standby mode, avoiding meaningless power consumption by each module from the source, further optimizing the overall power consumption of the device. At the same time, the trigger module 4 realizes the orderly linkage of parameter pre-calculation and image acquisition, ensuring that parameter pre-calculation is completed before image acquisition is started, ensuring both imaging effect and low power consumption operation, and effectively preventing invalid work caused by accidental touch, improving user operation convenience.

[0034] Please see Figure 2 In one embodiment, the ring body 1 includes: Inner ring 11, worn on the user's finger, has a cavity inside; image acquisition module 3 is housed in the cavity; and The outer cover 12 is slidably disposed on the inner ring 11 and has a stacked position and an interlaced position that is radially offset from the inner ring 11; the distance measuring unit 21, the light sensing unit 22 and the trigger module 4 are embedded in the outer cover 12. When the outer cover 12 is in the stacked position, the outer cover 12 blocks the acquisition end of the image acquisition module 3; when the outer cover 12 is in the staggered position, the acquisition end of the image acquisition module 3 is staggered from the outer cover 12 so as to be able to acquire the image of the target.

[0035] It should be noted that the inner ring 11, as the basic component for wearing the smart ring 100, has a closed-loop structure that fits the finger. It can be made of a skin-friendly, wear-resistant, and flexible material to conform to the curvature of the finger and ensure wearing comfort. It also has good resistance to deformation and wear, making it suitable for long-term daily wear. The inner ring 11 has an integrally molded cavity, which is a dedicated cavity for the image acquisition module 3. The cavity has a regular embedded structure, and the inner wall is made of an insulating and scratch-resistant material for fine treatment. This can effectively protect the components inside the cavity from wear and prevent the intrusion of external moisture and dust. The cavity has a transparent acquisition port corresponding to the acquisition end of the image acquisition module 3. This provides a stable and independent placement space for the image acquisition module 3 without affecting the normal operation of subsequent image acquisition. The image acquisition module 3 is housed inside the cavity, tightly fitted and firmly embedded in the inner wall of the cavity, preventing displacement or shaking during wear and ensuring the stability of the module's operation.

[0036] The outer cover 12 is slidably mounted on the inner ring 11. It is plate-shaped or has an arc-shaped structure that matches the curvature of the inner ring 11. It is made of a lightweight, wear-resistant, and smooth-sliding material. An embedded slide rail limiting structure 13 is used to connect the outer cover 12 and the inner ring 11. A sliding protrusion is provided on the inner side of the outer cover 12, and a matching sliding groove is provided on the outer side of the inner ring 11. The protrusion and groove fit tightly together, ensuring smooth, uninterrupted, and noiseless sliding of the outer cover 12, while also limiting its movement so that the outer cover 12 can only switch between overlapping and staggered positions, preventing it from falling off. To address issues such as misalignment, the distance measurement unit 21, the light sensing unit 22, and the trigger module 4 are all embedded in the outer cover 12. The outer cover 12 has pre-reserved fitting slots for each module, and each module fits tightly into the fitting slot. The outer side is sealed and protected with a sweat-resistant material. The distance measurement unit 21 and the light sensing unit 22 are always exposed and are not affected by the sliding position of the outer cover 12, so they can sense the external environment at any time. The trigger module 4 can achieve linkage control according to the position of the outer cover 12. The overall layout is compact and stable, avoiding loosening or malfunction during daily wear.

[0037] The outer cover 12 has two fixed working positions: a stacked position and a staggered position. When the outer cover 12 is in the stacked position, the outer cover 12 and the inner ring 11 are radially stacked and fitted together. The portion of the outer cover 12 corresponding to the acquisition port of the inner ring 11 completely covers the acquisition end of the image acquisition module 3. At this time, the image acquisition module 3 is tightly protected and cannot receive external image signals, while the distance measurement unit 21 and the light sensing unit 22 embedded in the outer cover 12 remain exposed and do not affect the core sensing function. When the outer cover 12 slides to the staggered position, which is radially offset from the inner ring 11, the outer cover 12... The overall structure is radially offset from the inner ring 11 cavity acquisition port, no longer obstructing the acquisition end of the image acquisition module 3, allowing the acquisition end to be fully exposed and enabling smooth image acquisition of the target. At this time, the distance measurement unit 21 and the light sensing unit 22 remain exposed, allowing for rapid environmental perception and parameter pre-calculation. Simultaneously, the position switching of the outer cover 12 can trigger the module 4 to form a dedicated control logic. It is set so that the trigger module 4 can only receive the shooting command and control the operation of each module when the outer cover 12 is in the staggered position. When the stacked position is not in the stacked position, the trigger module 4 cannot start the shooting function.

[0038] In this embodiment, the outer cover 12 adopts a sliding limiting structure 13 to facilitate convenient switching between stacked and staggered positions. The operation is simple and intuitive, and the control of occlusion and exposure is only implemented for the image acquisition module 3. The distance measurement unit 21 and the light sensing unit 22 are always exposed, which can sense the external environment at any time without repeatedly switching the exposure state, ensuring the timeliness of the sensing function, while avoiding the additional losses caused by frequent start-stop of the module. In addition, by setting that the camera can only take pictures when the outer cover 12 is open and in the staggered position, the power consumption of the device is further optimized from the control logic. When the outer cover 12 is closed and in the stacked position, even if the module 4 is accidentally triggered, the camera process cannot be started, thus eliminating unnecessary power consumption from the source.

[0039] Please see Figure 3 In one embodiment, the smart ring 100 further includes a flexible circuit board 5, which comprises: The first plate 51 is disposed in the cavity and is electrically connected to the image acquisition module 3. The second plate 52 is located on the side of the outer cover 12 near the inner ring 11 and is electrically connected to the distance measuring unit 21, the light sensing unit 22, and the trigger module 4; and The bendable plate 53 has one end extending into the cavity to connect with the first plate 51 and the other end extending into the cavity to connect with the second plate 52. The bendable plate 53 is configured to deform with the relative sliding of the outer cover 12 to maintain the electrical connection between the first plate 51 and the second plate 52.

[0040] It should be noted that the first plate 51 is the fixed arrangement part of the flexible circuit board 5. It has a flat sheet structure and is adapted to the arrangement environment of the inner ring 11 cavity. It uses a flexible substrate consistent with the main body of the flexible circuit board 5, and the surface is covered with a thickened insulating layer. It is fixedly arranged against the inner wall of the cavity and achieves a stable electrical connection with the image acquisition module 3 in the cavity. The connection part is treated with a sealed welding process to avoid poor contact caused by external moisture intrusion. It can not only stably transmit power to the image acquisition module 3, but also realize the signal communication between the image acquisition module 3 and other modules. Its arrangement position is adapted to the internal structure of the cavity, does not occupy the placement space of the image acquisition module 3, and does not affect the sealing and protection effect of the cavity. It always maintains a fixed shape and does not move with the sliding of the outer cover 12.

[0041] The second plate 52 is also the adaptation layout part of the flexible circuit board 5. It is an arc-shaped sheet structure that fits the inner arc of the outer cover 12. It is made of flexible substrate and can be tightly fitted to the side of the outer cover 12 near the inner ring 11. When laid out, it fits the flat area of ​​the inner side of the outer cover 12 without affecting the sliding fit between the outer cover 12 and the inner ring 11. The second plate 52 establishes a stable electrical connection with the distance measurement unit 21, the light sensing unit 22 and the trigger module 4 embedded in the outer cover 12. Each module has an independent conductive contact. The connection part is treated with anti-loosening encapsulation, which can stably transmit power to the three modules in a unified manner and realize the signal linkage transmission between the modules. It moves synchronously with the outer cover 12 and always maintains a stable fit with the outer cover 12. It will not fall off or have poor contact due to sliding.

[0042] The bendable plate 53 is the core transition part connecting the first plate 51 and the second plate 52. It is a seamless, integrated flexible structure, forming a continuous connection with the first plate 51 and the second plate 52 without any seams. Its flexible substrate possesses excellent repeated bending and deformation properties, withstanding multiple bends, stretching, and repositioning without easily experiencing circuit breakage or damage. One end of the bendable plate 53 extends into the cavity of the inner ring 11 and is fixedly connected to the first plate 51, while the other end extends to the inside of the outer cover 12 and is fixedly connected to the second plate 52. All connection points are reinforced to ensure strong connection. When the outer cover 12 slides relative to the inner ring 11 to switch positions, the bendable plate 53 adapts to the displacement of the outer cover 12. When the outer cover 12 is in the stacked position, the bendable plate 53 is in a naturally stretched or slightly bent state. When the outer cover 12 slides to the staggered position, the bendable plate 53 undergoes corresponding bending or stretching deformation with the displacement. Regardless of the deformation state, the internal conductive circuit can be kept unobstructed, and the power transmission and signal connection between the first plate 51 and the second plate 52 can be continuously guaranteed without connection interruption due to the sliding of the outer cover 12.

[0043] In this embodiment, the flexible circuit board 5 adapts to the structural layout of the inner ring 11 and the sliding outer cover 12, eliminating the need to reserve complex wiring space, making the circuit connection of each module more compact, and meeting the wearable structure requirements of the smart ring 100. At the same time, the flexible material has good sweat and corrosion resistance, adapting to daily wear scenarios, extending the service life of the circuit, and reducing the probability of circuit failure.

[0044] Please see Figure 3In one embodiment, the ring body 1 further includes a limiting structure 13, which includes a groove 131 and a sliding shaft 132. One of the groove 131 and the sliding shaft 132 is disposed on the outer peripheral wall of the inner ring body 11, and the other is disposed on the side of the outer cover body 12 near the inner ring body 11. The groove 131 extends along the sliding direction of the outer cover body 12. The sliding shaft 132 is slidably engaged with the groove 131, and the two end walls of the groove 131 abut against the sliding shaft 132 to limit the stacking position and the staggered position.

[0045] It should be noted that when the sliding shaft 132 slides along the sliding groove 131 to one end of the sliding groove 131 and comes into close contact with the groove wall at that end, the outer cover 12 is limited to the stacked position and is radially stacked and fitted with the inner ring 11, thus achieving shielding and protection of the image acquisition module 3 acquisition end; when the sliding shaft 132 slides along the sliding groove 131 to the other end until it comes into close contact with the groove wall at the other end of the sliding groove 131, the outer cover 12 is limited to the staggered position and is radially offset from the inner ring 11, no longer shielding the image acquisition module 3 acquisition end.

[0046] In this embodiment, the outer cover 12 is switched between two fixed working positions by the contact and limiting of the groove walls at both ends of the slide 131 and the slide shaft 132. This prevents structural damage caused by excessive sliding and allows the user to perceive clear limit feedback when switching positions, thus improving the ease of operation.

[0047] Please see Figure 3 In one embodiment, the smart ring 100 further includes: Thermoelectric power generation module 6 is disposed within the cavity. Thermoelectric power generation module 6 includes an input semiconductor 61 and an output semiconductor 62. The input semiconductor 61 is disposed near the inner ring wall of the cavity; the output semiconductor 62 is disposed on the outer ring wall of the cavity and is adapted to the shape of the ring body 1; and A boost module is housed in a cavity and connected to an output semiconductor 62, and is used to charge the battery.

[0048] It should be noted that the thermoelectric power generation module 6 consists of two parts: an input semiconductor 61 and an output semiconductor 62. It is made of semiconductor material with high thermoelectric conversion efficiency and has good thermoelectric conduction performance. It does not rely on an external power source and can realize energy conversion spontaneously through temperature difference. It is suitable for the low power consumption and self-powered energy supply requirements of the smart ring 100. The two are connected stably through conductive connectors to ensure uninterrupted energy transmission during thermoelectric conversion. At the same time, both are covered with an insulating and thermally conductive encapsulation layer, which not only ensures thermoelectric conduction efficiency but also isolates the risk of short circuits, making it suitable for sealed installation environments inside the cavity.

[0049] The input semiconductor 61 is positioned close to the inner ring wall of the cavity, which is directly connected to the inner side of the inner ring body 11. It conforms to the user's skin when wearing the device. The input semiconductor 61 adopts a structural design that fits the shape of the inner ring wall of the cavity, allowing it to fit tightly to maximize the contact area and improve heat conduction efficiency. Its heat-conducting surface faces the inner ring wall of the cavity, enabling it to quickly sense and absorb the heat transferred from the user's skin, converting the body temperature into a stable heat energy input. This provides a continuous heat source for thermoelectric conversion. The outer insulating encapsulation layer does not affect the heat conduction effect and avoids circuit interference with other components in the cavity, maintaining a stable heat energy receiving state. It can continuously collect body heat without additional operation.

[0050] The output semiconductor 62 is located on the outer ring wall of the cavity, which is connected to the outside of the ring body 1, making it easier to exchange heat with the external environment. The output semiconductor 62 adopts an arc-shaped structure that matches the shape of the ring body 1, which can be seamlessly attached to the outer ring wall of the cavity. The contact surface has good thermal conductivity, which can quickly dissipate its own heat to the external environment, forming a stable temperature difference with the input semiconductor 61. The temperature difference is the core condition for thermoelectric conversion. The input semiconductor 61 absorbs heat from the human body to form a high-temperature end, while the output semiconductor 62 dissipates heat to the outside to form a low-temperature end. The stable temperature difference between the two ends drives the movement of charge carriers inside the semiconductor, thereby continuously converting thermal energy into electrical energy and realizing autonomous power generation. Its arc-shaped structure is adapted to the layout of the outer ring wall of the cavity, without taking up extra space or affecting the overall regular shape of the ring body 1.

[0051] The boost module is housed within the cavity and employs a miniaturized integrated structure. It is compatible with the pre-reserved mounting positions within the cavity and does not conflict with the layout of components such as the thermoelectric power generation module 6, the battery, and the image acquisition module 3. The boost module is stably connected to the output semiconductor 62 of the thermoelectric power generation module 6 and receives the electrical energy transmitted by the output semiconductor 62. Since the electrical energy generated by thermoelectric power generation has a low voltage, it cannot directly charge the battery. The boost module integrates a miniature boost chip and voltage regulator components, which can boost the low-voltage electrical energy generated by the low temperature difference and convert the unstable current into a stable charging current to meet the charging voltage and current requirements of the battery. It establishes a dedicated charging circuit with the battery and only starts the boost and charging process when the thermoelectric power generation module 6 generates sufficient electrical energy. When there is no electrical energy input, it is in a low-power standby state and does not consume the battery's own power.

[0052] In this embodiment, the thermoelectric power generation module 6 generates electricity autonomously based on the natural temperature difference between the human body and the external environment, without relying on external charging or additional drive. It fully utilizes the body's heat resources in the wearable scenario to replenish the smart ring 100's power and extend the device's battery life. The input semiconductor 61 adheres to the inner ring wall of the cavity to absorb body heat, while the output semiconductor 62 adheres to the outer ring wall to dissipate heat. The boost module can boost and stabilize the low-voltage power generated by the thermoelectric power generation, converting it into charging power suitable for the battery, achieving effective energy recovery and utilization, and avoiding energy waste. The combination of thermoelectric power generation and the boost module forms an autonomous power replenishment system, reducing the inconvenience of frequent charging for users. At the same time, combined with the previous low-power control design, it optimizes both power supply and consumption, completely solving the problem of insufficient battery life of the smart ring 100, improving the device's battery life and user experience, and extending battery life.

[0053] In one embodiment, a through hole is formed in the outer peripheral wall of the ring body 1; the smart ring 100 also includes a heat-conducting structure 7, which includes: Heat sink 71, which is located outside the through hole and blocks the through hole; The heat-conducting component 72 includes a heat-conducting pillar and two heat-conducting sleeves. One end of the heat-conducting pillar is connected to the two heat-conducting sleeves located within the cavity, and the other end of the heat-conducting pillar passes through a through hole to connect to the heat sink 71. The two heat-conducting sleeves respectively enclose the image acquisition module 3 and the output semiconductor 62; and A seal is used to fill the space between the heat-conducting column and the through hole.

[0054] It should be noted that the location of the through hole avoids the area where the ring body 1 fits against the finger when worn, so as not to affect the wearing comfort. At the same time, it corresponds to the layout of the image acquisition module 3 and the output semiconductor 62 in the cavity, ensuring that the heat conduction component 72 can connect with each component.

[0055] The heat sink 71 is located outside the through hole and completely covers it. It has a sheet-like structure that conforms to the curvature of the outer wall of the ring body 1. Made of a lightweight metal with high thermal conductivity, it possesses excellent heat dissipation performance, quickly dissipating heat conducted to the surface to the external environment. The heat sink 71 fits tightly against the outer wall of the ring body 1, ensuring efficient heat dissipation without protruding from the surface of the ring body 1, thus not affecting the overall neat shape and fit of the ring. Its inner side is firmly connected to the heat-conducting pillar, ensuring rapid and efficient heat conduction without heat loss. The heat sink 71 can have concave and convex structures to increase the heat dissipation area and can also serve as a decorative pattern.

[0056] The heat-conducting component 72 comprises a heat-conducting pillar and two heat-conducting sleeves. It is made of a highly thermally conductive and flexible material, ensuring stable thermal conductivity for rapid heat transfer. It also possesses excellent insulation properties, preventing short circuits during heat conduction. The two heat-conducting sleeves respectively enclose the image acquisition module 3 and the output semiconductor 62 within the cavity. The sleeves have a wrap-around structure adapted to the shape of the corresponding modules, allowing for close contact with the module surface and maximizing the contact area. This enables rapid absorption of the heat generated by the image acquisition module 3 during operation, as well as the heat accumulated by the output semiconductor 62 during thermoelectric power generation, achieving simultaneous heat collection from both locations. The heat-conducting pillar is an integral elongated structure. One end extends into the cavity and connects to both heat-conducting sleeves, concentrating and conducting the heat collected by both sleeves. The other end passes through a through-hole in the outer peripheral wall of the ring body 1, stably connecting to the outer heat sink 71. This ensures orderly heat conduction from the module within the cavity to the outer heat sink 71. The heat-conducting pillar is neat and uninterrupted, with a smooth conduction path, effectively improving heat conduction efficiency.

[0057] The sealant fills the gap between the heat-conducting column and the through hole. It is made of flexible, high-temperature resistant sealing material and has good deformation adaptability and sealing performance. It can fit tightly with the outer wall of the heat-conducting column and the inner wall of the through hole, preventing external moisture and dust from entering the cavity through the gap of the through hole. This ensures the safe operation of core components such as the battery and image acquisition module 3 inside the cavity. At the same time, the sealant has a certain thermal conductivity and will not hinder the conduction of a small amount of heat between the heat-conducting column and the through hole. It will also not melt or deform due to the heat conduction of the heat-conducting column. It is suitable for the working environment of the heat-conducting structure 7. After the sealant is filled, there are no protrusions or gaps, and it does not affect the stability of the heat-conducting column or the overall structural integrity of the ring body 1.

[0058] In this embodiment, the heat-conducting structure 7, through the cooperation of the heat-conducting component 72 and the heat dissipation component 71, can simultaneously collect the residual heat of the image acquisition module 3 and the accumulated heat of the output semiconductor 62, achieving centralized and efficient heat dissipation, avoiding heat accumulation in the cavity, preventing high temperature from damaging precision components such as the image acquisition module 3 and the output semiconductor 62, ensuring stable operation of each module, extending the service life of the components, and improving the heat exchange efficiency between the output semiconductor 62 and the outside world, maintaining a stable temperature difference between the output semiconductor 62 and the input semiconductor 61, helping the thermoelectric power generation module 6 to continuously and efficiently generate electricity, and improving the self-replenishment effect.

[0059] Please see Figure 1 and Figure 2In one embodiment, the trigger module 4 includes two buttons 41, which are spaced apart around the circumference of the ring body 1. The two buttons 41 are configured such that at least one button 41 can generate a first control signal and a second control signal according to the user's operation, and control the distance measurement unit 21 and the light sensing unit 22 to perform detection work according to the first control signal, and control the image acquisition module 3 to perform shooting work according to the second control signal.

[0060] It should be noted that the spacing between the two buttons 41 is adapted to finger operation habits, avoiding the pressure area that the ring would exert on the finger when worn. When pressed, they have moderate rebound force and clear feedback, allowing users to easily perceive whether the operation has been effective. The inner side of the buttons 41 integrates a pressure sensing chip and a signal triggering component, which can capture the user's pressing operation and convert it into a corresponding control signal.

[0061] Users can trigger corresponding signals through different pressing methods. For example, a single light press can generate a first control signal. After receiving the first control signal, the trigger module 4 will simultaneously send a start command to the distance measurement unit 21 and the light sensing unit 22, control the infrared ranging chip to start distance detection with the transmitter and receiver tubes, calculate the distance between the shooting target and the ring body 1 and pre-calculate the focal length parameters, and at the same time control the ambient light sensor to start light intensity detection with the photosensitive component, and pre-calculate the exposure parameters accordingly. The entire detection process does not require the image acquisition module 3 to be started, only driving the low-power sensing unit to work, taking into account both detection efficiency and power consumption control.

[0062] After the distance measurement unit 21 and the light sensing unit 22 complete the detection and parameter pre-calculation, the user can generate a second control signal by pressing button 41 again. After receiving the second control signal, the trigger module 4 immediately sends a shooting command to the image acquisition module 3, controlling the miniature CCD image sensor to work with the lens assembly to quickly complete image acquisition based on the pre-calculated focal length and exposure parameters. This eliminates the need for additional calculations by the image acquisition module 3, ensuring both imaging quality and shortening shooting time. In addition, the two buttons 41 can support combined operations. Different operation modes, such as long-pressing a single button 41 or pressing both buttons 41 sequentially, can correspond to different shooting modes, adapting to diverse needs such as continuous shooting and time-lapse shooting. Moreover, the control signal generated by the button 41 is only effective when the outer cover 12 is in the staggered position and the image acquisition module 3 is exposed. When the outer cover 12 is closed, pressing the button 41 will not trigger any module to work, further preventing accidental power consumption.

[0063] In this embodiment, the two buttons 41 arranged circumferentially are adapted to finger operation habits. The arc-shaped flexible structure takes into account both wearing comfort and operation convenience. The clear pressing feedback improves the user operation experience. The sweat-resistant and wear-resistant material is suitable for daily wear scenarios and extends the service life of the buttons 41. The design of the two buttons 41 supports independent operation and combined operation, which can meet different shooting needs, adapt to diverse usage scenarios, and improve the practicality of the device. The pressing pressure corresponds to different control signals. The first control signal is triggered to start the perception detection, and then the second control signal is triggered to execute the shooting. This achieves an orderly connection between perception and shooting, which not only ensures sufficient parameter pre-calculation and improves image quality, but also avoids the high power consumption caused by the simultaneous start of modules, further optimizing the power consumption of the device.

[0064] In addition, both buttons 41 can be integrated on the surface of the outer cover 12 and arranged at intervals along the circumference of the outer cover 12. They are staggered with the distance measuring unit 21 and the light sensing unit 22 on the outer cover 12, without interfering with each other. They do not block the exposed sensing areas of the distance measuring unit 21 and the light sensing unit 22, and can be adapted to the finger operation. After the user slides the outer cover 12 open, he / she can directly raise his / her hand to operate without having to adjust the wearing posture. Furthermore, button 41 is located on the outer cover 12, which can form an anti-accidental touch logic linked to the position of the outer cover 12. When the outer cover 12 is in the stacked position and the image acquisition module 3 is covered, even if the user touches or squeezes the button 41, the button 41 will be locked and will not generate any control signal, thus completely preventing accidental press triggering in non-use scenarios. Only when the outer cover 12 slides to the staggered position and the image acquisition module 3 is exposed and ready, the button 41 will be unlocked and can normally receive the user's pressing operation to generate the first and second control signals. Physical anti-accidental touch is achieved from the structural layout, without the need for additional complex electronic control logic.

[0065] In one embodiment, button 41 includes: A touch body, disposed within the cavity and movable in the direction of pressing, with at least a portion of the touch body exposed outside the ring body, is used to sense changes in light caused by the user's finger moving on the touch body and to generate a first control signal; and The elastic wave component is located in the cavity and connected to the side of the touch body facing the center of the ring body 1. When the touch body is pressed, the touch body moves along the pressing direction and generates vibration. The elastic wave component is used to detect the vibration of the touch body and generate a second control signal. Among them, the environmental perception module 2 can receive the first control signal and perform detection work; the image acquisition module 3 can receive the second control signal and perform shooting work.

[0066] It should be noted that the touch body is made of a highly transparent and wear-resistant material, with a micro photosensitive component and a light-transmitting cavity integrated inside. The cavity contains a stable light source, which can form a uniform and closed sensing light path. When the user's finger touches or swipes across the exposed surface of the touch body, it will block or change the light path of the cavity, causing the internal light to change. The photosensitive component captures this light change and converts it into the first control signal without pressing. It is highly sensitive and not easily affected by external light. When the touch body is not in a sensing state, it maintains low power consumption standby, only keeping the internal light source working, resulting in extremely low energy consumption.

[0067] A connection point is reserved on the side of the touch body facing the center of the ring body 1 for stable connection with the elastic wave component. The connection part adopts a flexible connection structure, which not only ensures the flexibility of the touch body when pressed and moved, but also allows the vibration to be efficiently transmitted to the elastic wave component without vibration loss. When the touch body is actively pressed by the user, it can move smoothly into the cavity along the pressing direction. The pressing stroke is adapted to the finger pressing force. After pressing, it has a natural reset ability, which does not require an additional reset structure. During the movement, the touch body itself will generate uniform and stable vibration. The vibration frequency is adapted to the pressing force. When the force is moderate, the vibration is stable, avoiding vibration disorder caused by excessive pressing.

[0068] The elastic wave component is located inside the cavity and is firmly connected to the side of the touch body facing the center of the ring body 1. The entire component is a miniature integrated structure, staggered with other components within the cavity to avoid interference. The elastic wave component includes a vibration sensor and a signal conversion chip, which can quickly capture vibration signals generated when the touch body is pressed and moved, and effectively filter out interference vibrations caused by slight external shaking and collisions, preventing false triggering. The elastic wave component only responds to specific frequency vibrations generated by the touch body being pressed. After capturing the corresponding vibration, it immediately converts it into a second control signal. The signal transmission is stable and has no delay. In non-vibration detection mode, it is in low-power sleep mode, consuming no additional power, thus meeting the low-power requirements of the smart ring 100.

[0069] In this embodiment, the first control signal generated by the touch body is specifically transmitted to the environmental perception module 2. After receiving the signal, the environmental perception module 2 immediately activates the distance measurement unit 21 and the light sensing unit 22 to perform detection work, without needing to activate the high-power image acquisition module 3, thus achieving seamless wake-up detection and adapting to the environmental prediction requirements before rapid capture. The second control signal generated by the elastic wave component is specifically transmitted to the image acquisition module 3. After receiving the signal, the image acquisition module 3 quickly performs the shooting work based on the detection parameters completed by the environmental perception module 2, without the need for additional parameter calculations, ensuring imaging efficiency and quality. At the same time, the light sensing and pressure vibration of the touch body are triggered by independent logic. The light sensing only activates detection, while the pressure vibration only executes shooting. The two do not interfere with each other and must follow the linkage logic of the outer cover 12. Only when the outer cover 12 is in an interleaved position and the image acquisition module 3 is exposed can the two types of control signals take effect, further eliminating invalid triggering and power consumption.

[0070] Please see Figure 4 The present invention also provides a method of using the smart ring 100 as described above, the method comprising: S100: The distance between the target and the ring body 1 is monitored by the distance measurement unit 21, and the focal length parameter is pre-calculated based on the monitored distance; the ambient light intensity is monitored by the light sensing unit 22, and the exposure parameter is pre-calculated based on the monitored ambient light intensity. It should be noted that in this step, the distance measurement unit 21 adopts an infrared ranging scheme, with a built-in infrared emitting chip, infrared receiving component, and ranging calculation module. It can work independently without relying on the image acquisition module 3, and its low-power operation is adapted to the ring's battery life requirements. During operation, the distance measurement unit 21 emits an infrared signal towards the target and receives the feedback signal reflected by the target. After receiving the feedback signal, it calculates the actual distance between the target and the ring body 1 by measuring the signal transmission time and intensity, avoiding the high power consumption problem of traditional distance calculation relying on images. At the same time, it has a built-in focal length matching algorithm, which automatically pre-calculates and adapts the focal length parameters according to the monitored real-time distance. When the distance is close, a short focal length is matched to ensure clear details, and when the distance is far, a long focal length is matched to achieve distant scene capture. After the parameter pre-calculation is completed, it is temporarily stored in the module cache, waiting for subsequent configuration. In addition, monitoring the ambient light intensity through the light sensing unit 22 and pre-calculating the exposure parameters based on the monitored ambient light intensity is a key preliminary step to ensure uniform image brightness and true color. This is completed independently by the light sensing unit 22 on the ring. The light sensing unit 22 integrates an ambient light sensor and a light-sensitive component, which can capture the real-time ambient light intensity in the shooting scene, including complex lighting environments such as strong light, weak light, and backlight. At the same time, it can identify changes in light color temperature to avoid color cast in the image. Based on the monitored light intensity data, the light sensing unit 22 has built-in exposure calculation logic to automatically pre-calculate the appropriate exposure parameters. In strong light environment, it matches a low exposure value to prevent overexposure and whitening. In weak light environment, it matches a high exposure value to supplement brightness. In backlight scene, it adapts dynamic exposure parameters to balance the contrast between light and dark. After the parameters are calculated, they are cached synchronously with the focal length parameters to form a complete set of basic imaging parameters.

[0071] S200 configures the calculated focal length and exposure parameters to the image acquisition module 3 to control the image acquisition module 3 to perform image acquisition based on the focal length and exposure parameters.

[0072] It should be noted that this step is the parameter landing and image acquisition execution stage, realizing the linkage between the sensing parameters and the acquisition module. After the focal length and exposure parameters are pre-calculated and cached, the trigger module 4 receives the user's shooting command and simultaneously configures the two sets of parameters to the image acquisition module 3 housed in the inner ring body 11 of the ring with one click. The parameter transmission relies on the flexible circuit board 5 to achieve stable interconnection without delay or loss. After receiving the parameters, the image acquisition module 3 does not need additional calculation and debugging. It directly completes focusing based on the preset focal length parameters and adjusts the photosensitivity based on the preset exposure parameters, quickly starting the shooting process and capturing high-definition images. The parameters are accurately adapted throughout the process, avoiding the high power consumption and time consumption problems of the image acquisition module 3 calculating parameters by itself. This ensures image quality, shortens the shooting response time, and adapts to the computing power limitations of the small body of the ring, achieving efficient and low-power imaging.

[0073] The S300 transmits the collected image data to the mobile terminal; the mobile terminal is configured to store the image data and / or use AI to recognize and process the image data.

[0074] It should be noted that after the image acquisition module 3 completes the shooting, it quickly transmits the image data to the bound mobile terminal through the ring's built-in wireless transmission components (such as Bluetooth and low-power WiFi). The transmission process uses a low-power transmission protocol, which does not consume a large amount of power from the ring's battery. As a data processing terminal, the mobile terminal primarily ensures the secure storage of image data and can automatically categorize and create a dedicated album for easy access, organization, and preservation of commemorative memories. It also supports AI-based recognition and processing of image data, including but not limited to portrait beautification, pet outline optimization, highlighting of celebratory elements such as birthday cakes, and enhancement of scene atmosphere. It can also perform functions such as target recognition, text extraction, and image classification.

[0075] In this embodiment, the image acquisition method of the smart ring 100 avoids the high power consumption problem of repeated calculations in the acquisition module 3 by designing distance measurement and light sensing monitoring to perform pre-calculated parameters independently. Combined with a low-power data transmission protocol, this significantly reduces overall energy consumption, effectively alleviating the core pain point of the smart ring 100's limited battery capacity and extending the device's battery life. Furthermore, it achieves functional extension and value enhancement. By linking with a mobile terminal to complete image storage and AI processing, it not only compensates for the ring's insufficient local computing power and storage, allowing users to preserve precious daily moments, but also further explores the commemorative significance and practical value of images through AI optimization and recognition functions, meeting users' dual needs for image quality and functionality.

[0076] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent.
