Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] The following is combined Figures 1-22 This application describes the main structure of a smart ring and the smart ring itself, according to embodiments thereof.

[0027] like Figures 1 to 22 As shown, according to some embodiments of this application, a main structure of a smart ring is provided, including a first annular body 1, a second annular body 2, and a connecting body 3. The first annular body 1 has an axis along a first direction (refer to the X direction in the figures); the second annular body 2 is arranged side by side on one side of the first annular body 1 along the first direction; the connecting body 3 is connected between the first annular body 1 and the second annular body 2 in the first direction, and the connecting body 3 is made of an elastic material so that the second annular body 2 and the first annular body 1 have multiple relative degrees of freedom.

[0028] Specifically, in this embodiment, the main structure of the smart ring achieves high adaptability and improved wearing comfort for the human finger 11 through a combination design of a first annular body 1, a second annular body 2, and an elastic connecting body 3. The connecting body 3 is made of an elastic material, such as silicone or TPU, giving the two annular bodies multiple degrees of relative freedom. This allows the main structure to adapt to the relative translation, stretching, and bending deformations of the finger 11's surface, joint bending movements, etc., effectively solving the problems of traditional rigid smart rings being unable to match the finger 11's movements and causing a strong sense of foreignness when worn. Furthermore, the stretchability of the connecting body 3 can be controlled by adjusting its wall thickness; a thinner wall results in better stretching.

[0029] The flexible connection and the parallel layout of the two main bodies allow for compatibility with fingers 11 of varying thicknesses. They remain in close contact with the skin during finger flexion and extension, ensuring stability while not restricting normal finger movement, significantly improving flexibility and comfort in daily use. The first annular body 1 and the second annular body 2 can be either open or closed rings. Their material can be the same elastic material as the connecting body 3 to further enhance the fit between the main structure and the finger 11, or they can be made of rigid materials such as metal to increase the strength of the main structure and improve the structural reliability of the smart ring.

[0030] In the above structure, reference Figure 1 The connecting body 3 is connected between the first annular body 1 and the second annular body 2 in the first direction. That is, the first annular body 1 and the second annular body 2 are coaxial and spaced apart and arranged side by side in the first direction. The connecting body 3 can be set as an annular structure coaxial with the first annular body 1 and the second annular body 2. Its first circumferential end is connected to the end of the first annular body 1 near the second annular body 2, and its second circumferential end is connected to the end of the second annular body 2 near the first annular body 1, forming an annular structure with a larger width in the first direction, so as to be suitable for wearing.

[0031] The connecting body 3 can also be configured to include multiple arc segments coaxial with the first annular body 1, with the multiple arc segments spaced apart around the first direction, and each arc segment having its two sides connected to the first annular body 1 and the second annular body 2 respectively, to further improve the degree of freedom between the two bodies. The arc lengths of the multiple arc segments can be the same or different. Of course, the connecting body 3 can also include multiple strip-shaped elastic members extending along the first direction, with the multiple strip-shaped elastic members spaced apart around the first direction, and each strip-shaped elastic member having its two ends connected to the first annular body 1 and the second annular body 2 respectively. All of the above forms of the connecting body 3 can achieve the purpose of connecting between the first annular body 1 and the second annular body 2 in the first direction, thereby improving the degree of freedom between the first annular body 1 and the second annular body 2.

[0032] In this embodiment, the main structure relies on the split design of the elastic connecting body 3, the first annular body 1, and the second annular body 2. While ensuring freedom of movement, it also possesses excellent structural reliability and functional expandability. For example, the first annular body 1 and the second annular body 2 can independently support functional components such as electrodes, magnetic components, and circuit boards. The elastic connection achieves integrated electrical and structural connection. Combined with in-mold injection molding, internal components can be integrally encapsulated, improving waterproof, dustproof, and deformation resistance.

[0033] The relative degrees of freedom of the two main bodies provide a structural basis for functions such as flipping and stacking, which can not only achieve stable contact between the electrodes and the skin, but also facilitate wearing and disassembly, taking into account structural stability, functional integrity and the feasibility of mass production.

[0034] In some embodiments, the number of annular bodies can be increased. For example, third annular bodies 12 can be arranged side-by-side at intervals along the side of the first direction near the second annular body 2. Figure 22 As shown, the width of the main structure is further widened to meet the various functional requirements of the smart ring. The third ring-shaped main body 12 can also be connected to the second ring-shaped main body 2 by a connecting body 3 made of elastic material, so as to have multiple relative degrees of freedom with respect to the second ring-shaped main body 2, so as to realize the adaptation of the entire main structure to different users' fingers 11 and the bending and other movement requirements.

[0035] Optionally, such as Figures 4 to 6 As shown, a first connector 101 is provided on the first annular body 1, and a second connector 201 is provided on the second annular body 2; when the second annular body 2 is flipped and overlapped to the outer ring side of the first annular body 1, the first connector 101 and the second connector 201 can be detachably connected.

[0036] Specifically, in this embodiment, by respectively providing a first connector 101 and a second connector 201 on the first annular body 1 and the second annular body 2, the two can be detachably connected when the second annular body 2 is flipped and overlapped on the outer ring side of the first annular body 1, significantly improving the wearing stability and ease of use of the smart ring. This detachable connection method can reliably fix the two annular bodies in the overlapped state, preventing loosening, displacement, or accidental unfolding during wearing, and ensuring the overall stability of the ring.

[0037] Meanwhile, the detachable connection allows users to quickly fasten and detach the two main bodies according to their wearing needs, simplifying the wearing and removing process and improving the user experience. This structure, together with the elastic connecting body 3, ensures the overall rigidity after being stacked and fixed, while retaining a certain degree of deformation adaptability, taking into account the reliability of fixation, wearing comfort and operational flexibility, and adapting to the stable use needs in daily wear scenarios.

[0038] In one embodiment, the connector can be in the form of Velcro, with the first connector 101 as one side of the Velcro and the second connector 201 as the other side. The fastening and disengagement operations are simple and quick, achieving a reliable connection without complex structures. It is also thin and lightweight, without increasing the overall volume or wearing weight of the ring, and adapts to the deformation characteristics of the elastic body. The Velcro provides a firm fit, is not easily loosened, can be reused, has good durability, and is simple to process and assemble, facilitating mass production.

[0039] In addition to Velcro, the first connector 101 and the second connector 201 can also adopt buckles, magnetic snaps, hooks and loops, snap buttons, micro snaps, etc., all of which can achieve detachable fixing after the two ring-shaped main bodies are flipped and stacked, meeting the needs of different structural designs and usage scenarios.

[0040] Optionally, such as Figures 4 to 6 As shown, multiple first connectors 101 and multiple second connectors 201 are provided respectively; multiple first connectors 101 are sequentially spaced on the side of the first annular body 1 away from the second annular body 2 along the first direction, and multiple second connectors 201 are sequentially spaced on the side of the second annular body 2 away from the first annular body 1 along the first direction; and / or, the second annular body 2 is provided with a protrusion 202 on the side of the second annular body 2 away from the first annular body 1 along the first direction, and the second connectors 201 are provided on the protrusion 202.

[0041] Specifically, in this embodiment, by providing multiple spaced-apart first connectors 101 and second connectors 201 on the first annular body 1 and the second annular body 2 respectively, a balanced fixation at multiple points in the circumference can be achieved after the second annular body 2 is flipped and stacked, effectively improving the connection reliability and overall structural stability. The multiple connectors are distributed sequentially and spaced apart along the circumference, which allows for even distribution of force in the stacked state, avoiding the problem of concentrated force at a single point connection that easily leads to loosening or skewing. This ensures that the ring maintains its shape stability during the movement and bending of the finger 11, providing reliable support for stable contact between the inner electrode and the skin.

[0042] The above arrangement allows for flexible adjustment of the connection points and number based on the wearing force characteristics, adapting to different finger sizes and activity levels, while balancing connection strength and ease of operation. At the same time, the spacing avoids excessive structural complexity, maintains the elastic body's deformability, and enhances wearing comfort and product durability.

[0043] In one embodiment, by providing a protrusion 202 on the second annular body 2 and arranging the second connector 201 on the protrusion 202, a dedicated installation position for the second connector 201 can be provided without changing the annular size of the body or interfering with the layout of internal functional components, thereby optimizing the utilization of structural space.

[0044] The protrusion 202 keeps the second connector 201 away from the main annular area, making alignment clearer and fit smoother when flipping and stacking, reducing the difficulty of connection operations and improving the efficiency of wearing and removing the ring. This structure also avoids the problems of increased thickness and obtrusive appearance caused by directly setting the second connector 201 on the annular body, maintaining the overall thinness and beauty of the ring.

[0045] In addition, the protrusion 202 can also serve as a positioning and limiting function to ensure the stacking accuracy, while facilitating processing, molding and assembly, adapting to the one-piece injection molding process, which helps to reduce production costs, improve product consistency and mass production feasibility.

[0046] Optionally, such as Figures 1 to 9 As shown, the main structure of the smart ring also includes a first magnetic component 4 disposed in the first annular body 1 and a second magnetic component 5 disposed in the second annular body 2; when the second annular body 2 is flipped and overlapped to the outer ring side of the first annular body 1, the positions of each first magnetic component 4 and each second magnetic component 5 correspond to each other, so that the inner ring side of the first annular body 1 can be pressed tightly against the user's skin by repulsion.

[0047] Specifically, in this embodiment, by respectively arranging a first magnetic component 4 and a second magnetic component 5 within the first annular body 1 and the second annular body 2, when the second annular body 2 flips and overlaps with the outer ring side of the first annular body 1, the positions of the two sets of magnetic components correspond one-to-one and generate mutual repulsion, providing a stable and reliable active clamping force for the smart ring. This structure requires no additional mechanical buckles or complex transmission mechanisms; it relies solely on magnetic repulsion to drive the first annular body 1 to move inward toward the finger 11. Figure 15 and Figure 16 As shown, this design ensures a close fit between the inner ring and the user's skin, fundamentally improving wearing stability and preventing the ring from loosening, shifting, or falling off during daily activities.

[0048] In addition, the two sets of magnetic components are built into the ring-shaped main body, which does not occupy external space, does not damage the product's appearance and unibody structure, and can precisely adjust the repulsive force by controlling the magnetic parameters to adapt to the wearing needs of different users, while taking into account both structural simplicity and functional reliability.

[0049] Furthermore, the aforementioned magnetic components and structure can significantly improve the detection accuracy and wearing experience of the smart ring, offering outstanding advantages in scenarios such as health monitoring and biosignal acquisition. Under the action of magnetic repulsion, the inner electrode or sensing surface of the first annular body 1 can stably and uniformly adhere to the skin surface, ensuring the continuity of signal acquisition and detection accuracy, and eliminating signal noise and measurement errors caused by gaps.

[0050] The repulsion drive is a non-contact actuation method, eliminating mechanical wear, ensuring a long service life, and providing rapid response. It can adjust the clamping effect in real time according to usage conditions. Wearing and removing the device is simple; the clamping state is released by disconnecting the power or removing the magnetic field, greatly improving ease of use. The overall structure is compatible with elastic one-piece injection molding processes, providing excellent protection for internal components, making it waterproof and dustproof, suitable for mass production and long-term daily wear.

[0051] Optionally, such as Figures 10 to 19 As shown, at least one of the first magnetic component 4 and the second magnetic component 5 is an electromagnet component; and / or, the first magnetic component 4 includes a plurality of electromagnets 401, the second magnetic component 5 includes a plurality of permanent magnets 501, the number of electromagnets 401 is the same as the number of permanent magnets 501, and they are respectively covered on the outer ring side of the first annular body 1, and the permanent magnets 501 are one-to-one corresponding to the electromagnets 401 covered in the second annular body 2.

[0052] Specifically, in this embodiment, at least one of the first magnetic component 4 and the second magnetic component 5 is configured as an electromagnet component, which enables controllable adjustment and active switching of the magnetic repulsion force, significantly improving the flexibility and safety of the smart ring. By controlling the energizing state and current magnitude of the electromagnet 401, the magnetic field strength can be precisely changed, thereby adjusting the pressure on the skin to meet the fastening needs of different users in different scenarios. After power is cut off, the magnetic field disappears, and the pressure is released, making it easy to put on and take off the ring. This design achieves force control without modifying the mechanical structure, and the control method is simple and efficient, improving the product's intelligence level and user experience.

[0053] In one embodiment, multiple electromagnets 401 and multiple permanent magnets 501 are arranged in an equal, one-to-one correspondence, and are respectively wrapped around the outer ring of the first annular body 1 and inside the second annular body 2. This ensures that the magnetic repulsion force is evenly distributed and precisely aligned circumferentially, guaranteeing a stable and balanced clamping force. The separate wrapping layout of the electromagnets 401 and permanent magnets 501 is reasonable, does not interfere with the internal circuit board and electrode layout, and makes full use of the annular space, resulting in a more compact product structure. The circumferential multi-point alignment and repulsion force can avoid excessive local force or bias, allowing for more stable contact between the inner electrode and the skin, thus improving signal acquisition accuracy.

[0054] Meanwhile, both the electromagnet 401 and the permanent magnet 501 are covered and fixed by the main body material, which has high positioning accuracy and high reliability. They can be injection molded in one piece, simplifying the assembly process, improving the waterproof and dustproof performance and structural strength of the product, and making them suitable for mass production.

[0055] Optionally, such as Figures 10 to 19As shown, the main structure of the smart ring also includes a plurality of first electrodes 6, which are spaced apart and exposed on the surface of the inner ring side of the first annular body 1; and / or, the main structure also includes a plurality of second electrodes 7, which are spaced apart and exposed on the surface of the inner ring side of the second annular body 2.

[0056] Specifically, in this embodiment, by providing multiple exposed first electrodes 6 at intervals on the inner ring side of the first annular body 1, and selectively providing multiple exposed second electrodes 7 on the inner ring side of the second annular body 2, the signal acquisition capability and wearing detection stability of the smart ring can be significantly improved. The multiple electrodes are distributed circumferentially at intervals, which increases the contact area with the skin of the finger 11. This ensures that at least some electrodes reliably contact the skin when the finger 11 bends, moves its joints, or changes its posture, effectively avoiding signal interruption or detection errors caused by gaps or displacement. The number and arrangement of the first electrodes 6 and the second electrodes 7 can be the same or different.

[0057] Furthermore, the exposed electrode layout ensures the sensitivity and accuracy of sensor data acquisition, meeting the monitoring needs of various physiological signals such as heart rate, ECG, and bioimpedance. Simultaneously, the independent deployment of multiple electrodes enables simultaneous acquisition and cross-validation of multiple signals, improving data accuracy and anti-interference capabilities. The integrated design of the electrodes and the ring-shaped main body results in a compact structure and simple assembly. The use of elastic and stretchable materials does not compromise wearing comfort, balancing functional integrity, reliability, and user experience, providing stable support for the health monitoring functions of the smart ring.

[0058] Optionally, such as Figures 13 to 16 As shown, when the second annular body 2 is flipped and overlapped onto the outer ring side of the first annular body 1, there is a set gap between the connecting body 3 and the first annular body 1.

[0059] Specifically, in this embodiment, when the second annular body 2 is flipped and overlapped onto the outer ring side of the first annular body 1, a set distance is maintained between the connecting body 3 and the first annular body 1. This provides the necessary movement space for the magnetic repulsion drive and elastic deformation of the smart ring, effectively ensuring functional realization and structural reliability. This distance can prevent interference, compression, or friction between the connecting body 3 and the first annular body 1 in the overlapped state, ensuring that when the electromagnet 401 and the permanent magnet 501 generate repulsion, the first annular body 1 can move smoothly toward the finger 11, and the second annular body 2 can be lifted upwards simultaneously, allowing the connecting body 3 to fully stretch and deform to absorb the displacement.

[0060] The presence of a pre-defined spacing allows for precise control of the structural gaps and movement stroke after stacking, ensuring uniform and controllable pressure of the electrodes on the skin and preventing functional failure due to structural jamming. Simultaneously, this design reduces localized stress concentration in the elastic material, improving the lifespan and fatigue resistance of the connecting body 3. This allows the ring to maintain stable operation during repeated wearing, flipping, and charging / discharging, balancing wearing comfort, structural safety, and functional stability.

[0061] Optionally, such as Figure 1 and Figure 4 As shown, the connecting body 3 is configured as a ring structure extending around the axis; and / or, the connecting body 3 includes multiple connecting segments, which are sequentially and spaced apart between the first ring body 1 and the second ring body 2 around the axis.

[0062] Specifically, in this embodiment, the connecting body 3 is configured as a ring structure extending around the axis, which allows for a continuous and uniform elastic connection between the first ring body 1 and the second ring body 2, resulting in a more balanced stress distribution and higher overall structural strength and stability. The full-ring connection effectively improves the overall structural integrity, avoids localized stress concentration, and is less prone to tearing or failure during stretching, bending, and flipping, thus enhancing durability. Simultaneously, it provides complete protection for internal components, improving waterproof and dustproof capabilities.

[0063] The continuous ring structure facilitates one-piece injection molding, has a simple process, good mass production capability, and can stably provide bidirectional uniform elastic deformation, ensuring smooth relative movement of the two ring-shaped main body and consistent wearing fit, thereby improving wearing comfort and product reliability.

[0064] In one embodiment, the connecting body 3 can also adopt a multi-segmented interlocking structure, which can significantly improve the elastic deformation capability and freedom of movement while ensuring a reliable connection, making the two ring-shaped bodies more flexible in stretching, bending, and swinging. The segmented design reduces local constraints, adapts to the complex movements of the 11 finger joints, and makes wearing more comfortable. The interlocking layout can reduce the weight of the product, reduce the amount of material used, and at the same time enhance breathability and improve the long-term wearing experience.

[0065] The multiple connecting sections allow for flexible adjustment of their number, length, and wall thickness, precisely controlling elasticity and stiffness to meet different size and wearing requirements. This structure is also compatible with in-mold injection molding, offering high space utilization, effectively preventing deformation and jamming, and balancing connection stability, movement flexibility, and production economy.

[0066] Optionally, the second annular body 2 and the first annular body 1 have at least the following relative degrees of freedom: relative translational degree of freedom, relative tensile degree of freedom, and relative bending degree of freedom.

[0067] Specifically, in this embodiment, by limiting the relative translation, relative stretching and relative bending degrees of freedom between the second annular body 2 and the first annular body 1, the smart ring can fully adapt to the physiological structure and movement characteristics of the human finger 11, significantly improving wearing adaptability and comfort.

[0068] Among them, the relative translational degree of freedom allows the two annular bodies to be slightly misaligned along the circumferential or radial direction, adapting to the uneven shape of the finger 11 surface, such as... Figure 3 As indicated by the black arrow; the relative stretching freedom can adapt to the wearing needs of fingers of different thicknesses 11, achieving adaptive tightness adjustment, such as... Figure 3 As shown by the hollow arrow in the image; the relative bending freedom can deform synchronously with the bending of the finger 11 joint, without hindering the normal flexion and extension movements of the finger 11, and can also cause the second annular body 2 to flip and overlap onto the outer ring side of the first annular body 1, as shown in the image. Figures 17 to 19 As shown.

[0069] The three degrees of freedom work together to fundamentally solve the problems of traditional rigid smart rings, such as sticking, joint pressure, and easy loosening and displacement, ensuring that the ring always fits the skin and remains stable during daily activities. This design relies on the elastic connecting body 3 to achieve multi-dimensional free deformation. The structure is simple and reliable, taking into account wearing flexibility, usage stability and wearing experience, while also facilitating one-piece injection molding to meet mass production requirements.

[0070] Optionally, such as Figure 1 and Figure 4 As shown, the first annular body 1, the second annular body 2, and the connecting body 3 are all made of elastic material and are integrally molded into the main structure.

[0071] Specifically, in this embodiment, the first annular body 1, the second annular body 2, and the connecting body 3 are all made of elastic material and integrally molded, which can significantly improve the integrity, sealing, and reliability of the overall structure of the smart ring. The integrally molded structure has no seams, providing stronger waterproof, dustproof, and deformation resistance capabilities, effectively protecting internal components such as the FPC, electrodes, and magnetic components, and extending the product's lifespan. The elastic material gives the entire structure excellent tensile, bending, and resilience properties, ensuring wearing comfort and freedom of movement. At the same time, this structure simplifies the assembly process, reduces production costs, is suitable for one-time in-mold injection molding, improves production efficiency and product consistency, and balances structural stability, wearing comfort, and the needs of large-scale mass production.

[0072] Optionally, such as Figures 4 to 7 As shown, the main structure of the smart ring also includes a first circuit board 8, which is arranged in a ring shape within the first ring-shaped main body 1.

[0073] Specifically, in this embodiment, the first circuit board 8 is arranged in a ring shape inside the first ring-shaped body 1, which can make full use of the ring space, making the circuit layout more compact and the overall product thinner and lighter, which meets the miniaturization design requirements of smart rings.

[0074] The annular circuit board is highly matched with the annular structure of the first annular body 1, resulting in more precise installation and positioning, and more even force distribution. This effectively improves structural stability and prevents damage or poor contact caused by stretching or bending. This built-in installation method provides complete protection for the circuit board, enhancing its waterproof, dustproof, and impact resistance capabilities without affecting appearance or wearing comfort. The annular layout also facilitates the uniform arrangement and electrical connection of functional components such as electrodes and magnetic components, simplifies internal wiring, and improves signal acquisition and power supply stability.

[0075] Optionally, such as Figures 1 to 3 As shown, the main structure of the smart ring also includes a second circuit board 9 and a connecting circuit board 10; the second circuit board 9 is arranged in a ring shape inside the second ring-shaped main body 2, and the connecting circuit board 10 is arranged inside the connecting main body 3. The second circuit board 9 is connected to the first circuit board 8 through the connecting circuit board 10.

[0076] Specifically, in this embodiment, by setting an annular second circuit board 9 within the second annular main body 2 and a connecting circuit board 10 within the connecting main body 3, a stable electrical connection is achieved between the first circuit board 8 and the second circuit board 9, ensuring reliable synchronous signal and power supply for the dual-main-body structure. The annular circuit board is spatially and vertically adapted to the annular main body, resulting in a compact layout, uniform stress distribution, and the ability to deform synchronously with the elastic body without easily breaking.

[0077] The connecting circuit board 10 is built into the elastic connecting body 3, which is fully protected and can deform freely with stretching and bending without affecting relative movement. The overall structure and circuit are integrated into one design, with good waterproof and dustproof performance, simplified assembly process, and suitable for in-mold injection molding, providing a reliable guarantee for the multi-functional expansion and long-term stable operation of the smart ring.

[0078] The first circuit board 8, the second circuit board 9, and the connecting circuit board 10 can all be FPCs.

[0079] According to the second aspect of this application, such as Figures 10 to 22 As shown, a smart ring is provided, including: a main structure in the first aspect.

[0080] Specifically, in this embodiment, by applying the aforementioned main structure to the smart ring, the product achieves comprehensive improvement in terms of structural adaptation, wearing experience, functional implementation, and process reliability.

[0081] The smart ring adopts a flexible split ring-shaped main body and an elastic connecting main body 3, which has multiple degrees of relative freedom and can adapt to the unevenness of the finger 11 surface and the bending movement of the joint, solving the problems of discomfort, restriction of finger 11 movement, and easy loosening and displacement of traditional rigid rings.

[0082] The flip-over and detachable connection structure ensures a secure fit and easy assembly / disassembly. The built-in electromagnet 401 and permanent magnet 501 work together to generate a controllable magnetic repulsion force, driving the inner electrodes to fit tightly against the skin, ensuring accurate and stable collection of physiological signals.

[0083] The entire unit is made of elastic material through one-piece injection molding, which is waterproof, dustproof, deformation resistant, and durable. The internal circuit board and components are arranged in a compact and reasonable manner, and the signal transmission and power supply are stable and reliable.

[0084] This smart ring combines comfort, stability, intelligence, and mass production feasibility, meeting the needs of daily long-term wear and suitable for various application scenarios such as health monitoring and intelligent interaction.
