In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0039] A smart ring is a wearable device that integrates multiple functions such as health management, activity monitoring, and communication. Related technologies typically use screws, clips, or other locking devices to secure the ring after adjustment. However, these methods lack the ability to automatically maintain clamping force after adjustment, making them prone to displacement due to finger movement or the weight of the device.

[0040] This application provides a smart ring, such as Figure 1 and Figure 2As shown, the smart ring 1000 includes a ring body 100 and a ring structure 200.

[0041] The main body of the ring 100 typically integrates functional components such as a battery, display panel, motherboard, and various sensors. These functional components work together to enable the smart ring 1000 to have intelligent functions such as time display, health monitoring (heart rate, blood oxygen, etc.), and notification reminders.

[0042] Both ends of the ring structure 200 are connected to the ring body 100 to form a ring structure. At least one end of the ring structure 200 is slidably connected to the ring body 100 along the circumference of the smart ring 1000. That is, one end of the ring structure 200 is slidably connected to the ring body 100 along the circumference, while the other end can be fixed, rotatably connected, or slidably connected to the ring body 100. At least one end of the ring structure 200 slides along a first direction under the action of external force, thereby increasing the inner diameter of the smart ring 1000 to accommodate fingers of different sizes; that is, when wearing the smart ring 1000, the ring structure 200 will expand outward due to the pressure of the finger, such as... Figure 2 As shown, it automatically adjusts to match the wearer's finger size. The ring structure 200 maintains a tendency to contract towards its central axis. When worn, this contraction tendency enhances the stable clamping force, preventing the ring from slipping off. When removing the ring, the contraction tendency of the ring structure 200 causes at least one end of the ring structure 200 to slide along a second direction, reducing the inner diameter of the smart ring 1000, allowing the smart ring 1000 to automatically return to its minimum inner diameter, such as... Figure 1 As shown.

[0043] The first direction is either clockwise or counterclockwise along the circumference of the smart ring 1000, and the second direction is opposite to the first direction; for example... Figure 1 and Figure 2 As shown, both ends of the ring structure 200 are slidably connected to the ring body 100. Dividing the two ends of the ring structure 200 into left and right ends according to their positions, moving the left end of the ring structure 200 counterclockwise and the right end clockwise increases the inner diameter of the smart ring 1000. Moving the left end of the ring structure 200 clockwise and the right end counterclockwise decreases the inner diameter of the smart ring 1000.

[0044] In some embodiments, such as Figure 3 and Figure 4As shown, the ring body 100 includes a housing 120 with an inner cavity. Some functional components, such as batteries, circuit boards, and electronic components, can be installed in the inner cavity of the housing 120. The housing 120 can protect the functional components installed in the inner cavity. Some functional components can also be installed on the outer peripheral wall or radially outward of the housing 120. For example, decorative functional components, display screens, and interactive buttons. Installing these functional components on the outer peripheral wall or radially outward of the housing 120 facilitates operation and observation by the wearer.

[0045] For ease of description, the end of the ring structure 200 that is slidably connected to the ring body 100 is referred to as the sliding connection end. One end of the ring structure 200 may be the sliding connection end, or both ends of the ring structure 200 may be sliding connection ends. A groove 110 is provided on the radially inner side of the ring body 100. The sliding connection end of the ring structure 200 is slidably disposed within the groove 110. The groove 110 guides the movement of the sliding connection end, providing a clear movement trajectory and preventing unnecessary axial deformation of the ring structure 200. Furthermore, when the ring structure 200 is adjusted to any inner diameter, the sliding connection end has a unique position, maintaining the connection stability between the ring body 100 and the ring structure 200.

[0046] The groove 110 is typically designed as an arc segment centered on the central axis. The extension path of the groove 110 is conjugate to the movement trajectory of the sliding connection end of the ring structure 200, ensuring smooth and low-friction movement of the sliding connection end within the groove 110 and improving the smoothness of sliding. The groove 110 can be located radially inward of the ring body 100, reducing the gap difference between the contact surface between the ring body 100 and the finger and the inner surface of the ring structure 200, making the smart ring 1000 fit the finger more closely and improving wearing stability and comfort.

[0047] Specifically, the radially inner side of the housing 120 has an arc-shaped inner wall and two flanges 122 located on both axial sides of the arc-shaped wall 121; the arc-shaped wall 121 and the two flanges 122 form a first groove 111; the opposite side of the flanges 122 has a second groove 112 communicating with the first groove 111, and the sliding groove 110 includes the first groove 111 and the second groove 112; the first groove 111 mainly serves as the receiving space for the ring structure 200, and the second groove 112 provides a sliding track. Furthermore, when the smart ring 1000 is worn, the flanges 122 contact the finger; thus, the portion of the ring structure 200 located within the sliding groove 110 does not contact the finger, avoiding discomfort to the finger caused by the sliding connection section during sliding, and improving wearing comfort.

[0048] Understandably, the extension path of the guard edge 122 is consistent with the extension path of the curved wall surface 121, that is, the guard edge 122 is also a curved structure, which matches the natural curve of the finger, thereby further improving the wearing comfort.

[0049] The two ends of the second groove 112 do not directly penetrate the retaining edge 122. That is, the solid structure of the retaining edge 122 at the two ends of the second groove 112 forms a limiting part 123. The limiting part 123 is used to contact a part of the finger ring structure 200 to limit the sliding stroke of the connecting part 220. This prevents the finger ring structure 200 from coming off during sliding.

[0050] Based on the above embodiments, such as Figure 4 As shown, the housing 120 also includes a connecting rib 124, which connects the two flanges 122, thereby enhancing the overall structural strength of the housing 120 and enabling it to better resist deformation and damage under external forces. A gap exists between the connecting rib 124 and the arc-shaped wall 121, through which the finger ring structure passes. When the sliding connection end slides along the second groove 112, the inner diameter of the finger ring structure continuously changes, and the shape of the finger ring structure does not perfectly match the trajectory of the arc-shaped wall 121. By providing the connecting rib 124, a radial limiting function can be achieved.

[0051] The number of connecting ribs 124 can be multiple, and the multiple connecting ribs 124 are arranged at intervals along the circumference. At least two connecting ribs 124 are close to the two ends of the circumference of the slide groove 110, thereby defining the start and end points of the ring structure located outside the ring body 100, and making the part of the ring structure located inside the slide groove 110 covered by the edge 122 and the connecting ribs 124, thereby maintaining the aesthetics of the external structure of the smart ring.

[0052] In other embodiments, such as Figure 5 As shown, the ring body 100 also includes a cover plate 130, which is detachably connected to the housing 120 and located radially inside the housing 120. A through hole 140 communicating with the first groove is formed between the cover plate 130 and the housing 120, through which the ring structure passes. The cover plate 130 and the housing 120 are detachably connected, such as by a snap, thread, or magnetic attraction. This design allows the cover plate 130 to be easily removed during assembly, facilitating the installation of the end of the ring structure into the first and second grooves. After assembly, the cover plate 130 is placed back on the radially inside of the housing 120, forming a stable and aesthetically pleasing overall structure. The cover plate 130 can replace the function of the connecting rib, shielding and limiting the ring structure located within the groove.

[0053] like Figure 1 and Figure 2As shown, the ratio of the circumferential length of the ring body 100 to the circumferential length of the smart ring 1000 ranges from [1 / 6, 1 / 3], meaning the central angle corresponding to the ring body 100 is between 60° and 120°. The ring body 100 needs to retain sufficient circumferential length to provide a sufficient sliding path and adjustment range, while avoiding excessive circumferential length of the ring body 100 that would prevent the smart ring 1000 from fully fitting the finger. In some embodiments, the ring band structure 200 can adjust the ring size between 17 and 21, or the length of the ring band structure 200 and the length of the slide groove 110 can be increased to achieve a wider range of adjustment; this application does not limit this.

[0054] In the first example of the above embodiments, the ring structure 200 has a preset curvature that contracts towards the central axis in its natural state, and the diameter corresponding to the preset curvature is [value missing]. The natural state of the ring structure 200 refers to the state in which the ring structure 200 acts as an independent component, with its two ends not limited by other components and not subjected to any external force. The ring structure 200 itself has a certain elasticity and deformation capability. In its natural state, the ring structure 200 presents an arc segment, or a ring shape with both ends in contact with the ground, or a ring shape with overlapping ends. This application does not limit this.

[0055] The diameter corresponding to the preset curvature is smaller than the minimum inner diameter of the smart ring 1000. By assembling the ring structure 200 to the ring body 100, the ring structure 200 is pre-expanded to form a structural pre-tightening force. When the ring structure 200 is subjected to external force, such as when the finger squeezes the ring structure 200 during wear, at least one end of the ring structure 200 slides circumferentially to expand its inner diameter to accommodate the finger; after the external force is removed, the ring structure 200 slides in the opposite direction according to its own elastic contraction tendency, returning to the pre-tightened state.

[0056] In the pre-expanded state, the ring structure 200 always maintains a contraction trend, dynamically adjusting between the minimum inner diameter and the expanded inner diameter without the need for an external locking device, ensuring continuous clamping force. Even if the finger size is close to the minimum inner diameter of the smart ring 1000, the pre-tightening force still provides sufficient contact pressure to prevent loosening.

[0057] In the second example of the above embodiment, the two ends of the ring structure 200 are connected by an elastic element, such as a spring or sheet. When a finger is inserted into the ring, the ring structure 200 is compressed, and the elastic element deforms, thereby increasing the inner diameter of the ring to accommodate the finger size. Once the finger is removed, the elastic element returns to its original shape, causing the ring structure 200 to shrink back to a smaller diameter. This example achieves automatic adjustment of the inner diameter of the smart ring 1000 through the deformation and recovery of the elastic element.

[0058] In the third example of the above embodiments, one end of the ring structure 200 is connected to the ring body 100 via an elastic element. The principle of the third example is the same as that of the second example, both achieving adjustment of the inner diameter of the smart ring 1000 through the deformation and recovery of the elastic element.

[0059] The first, second, and third examples described above represent different implementations of adjusting the inner diameter of the smart ring 1000 using the ring structure 200. This application may adopt the structure from any of the above examples, and this application does not limit it in this regard.

[0060] Based on the first example above, such as Figure 3 As shown, the ring structure 200 may include a deformable portion 210 and a connecting portion 220. The deformable portion 210 is the part of the ring structure 200 capable of elastic deformation, and at least one end of the deformable portion 210 is connected to the connecting portion 220. This allows the deformable portion 210 to deform under external force, thereby adjusting the overall size of the ring structure 200 to accommodate fingers of different sizes. Along the axial direction of the smart ring 1000, both ends of the connecting portion 220 protrude from the deformable portion 210; at least a portion of the deformable portion 210 is located within the first groove 111, that is, the deformable portion 210 is radially limited between the connecting rib 124 and the arc-shaped wall 121. The two ends of the connecting portion 220 are slidably disposed in the second groove 112, corresponding one to one. The connecting part 220, which is the part that slides in contact with the inner wall of the groove 110, can significantly reduce the actual sliding contact between the ring structure 200 and the ring body 100, and reduce the sense of resistance caused by the continuous change of the inner diameter of the ring structure 200 and the incomplete match with the shape of the groove 110.

[0061] The deformation section 210 can be made of a high-elasticity alloy only in part, while other parts can be made of other materials such as stainless steel or plastic. This allows for cost reduction and optimization of overall performance while meeting elastic deformation requirements.

[0062] The deformation part 210 can be made entirely of a highly elastic alloy, so that the entire deformation part 210 can exhibit excellent elastic recovery and corrosion resistance, ensuring that the ring always maintains a tight fit and stability during long-term use.

[0063] The high-elasticity alloy has excellent elastic recovery ability. This property allows the deformation part 210 to deform to adapt to the size of the finger when squeezed or stretched by the finger, and to immediately return to its original shape after the external force is removed, ensuring the tight fit and stability of the ring.

[0064] High-elasticity alloys can be selected from high-elasticity titanium alloys, nickel-titanium shape memory alloys, etc., and this application does not limit them.

[0065] like Figure 3 and Figure 6As shown, when only a portion of the deformable part 210 is made of a high-elasticity alloy, the deformable part 210 may include an insulating layer 211 and a deformable skeleton 212, the deformable skeleton 212 being made of a high-elasticity alloy. The deformable skeleton 212 is embedded within the insulating layer 211, which protects and isolates the deformable skeleton 212. The circumferential length of the deformable skeleton 212 is consistent with the circumferential length of the entire finger ring structure 200, thus providing deformation capability and clamping force along the entire circumferential length. Figure 7 As shown, the deformable skeleton 212 can also be disposed on the radial outer side of the insulating layer 211.

[0066] In some embodiments, the stiffness of the connecting portion 220 is greater than the stiffness of the deformable portion 210. The stiffness of the connecting portion 220 refers to its ability to resist deformation. In both structures, the stiffness of the connecting portion 220 is intentionally designed to be greater than that of the deformable portion 210 to ensure that the connecting portion 220 remains relatively stable when adjusting the ring size, while the deformable portion 210 can deform smoothly. The connecting portion 220 can reduce its deformation capacity by thickening it or using other materials, thereby preventing the connecting portion 220 from coming out of the second groove 112.

[0067] The ring structure 200 features a rounded chamfer along both circumferential edges of the smart ring 1000, reducing friction and pressure on the fingers and improving wearing comfort. Simultaneously, the rounded edges are smoother, reducing the risk of scratching the fingers.

[0068] The thickness of the ring structure 200 decreases gradually along both sides of the axial direction near the smart ring 1000. The inner wall of the ring structure 200 exposes a portion of the knuckle and finger within the ring body 100. The inner wall of the ring structure 200 is parallel to the central axis, ensuring even pressure distribution on the contact surface with the finger. The middle portion of the outer wall of the ring structure 200 protrudes radially outward, forming an arched reinforcing structure. This increases the bending stiffness of the deformable part 210, thereby enhancing the gripping force of the smart ring 1000 on the finger during wear and preventing the ring from accidentally slipping off during activities.

[0069] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
