Description

Technical Field

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

[0002] With the development of wearable device technology, smart rings are gradually gaining widespread use due to their small size, ease of wear, and ability to monitor heart rate, blood oxygen, and sleep. Current smart rings typically employ a closed ring structure, with their inner diameter fixed after production. Users need to select the appropriate size based on their finger size.

[0003] However, the size of human fingers can change due to factors such as temperature, exercise, and edema. Smart rings with a fixed inner diameter are difficult to adapt to the size requirements of different usage conditions, and may easily become too tight or too loose, affecting wearing comfort, and even posing a risk of the ring getting stuck on the finger or falling off and being lost.

[0004] Meanwhile, fixed-size structures are typically only suitable for specific fingers, making it difficult for users to switch between different fingers as needed, resulting in poor flexibility and low versatility. Therefore, how to provide a smart ring that can adapt to different finger sizes and maintain stable wear has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a smart ring that can change its inner diameter.

[0006] To address the aforementioned technical problems, this application provides a smart ring, comprising: a ring body having a circumferentially extending receiving channel; an adjustment band having its two ends connected to the ring body and together with the ring body forming a wearing hole for a finger to pass through; the adjustment band being movable along the receiving channel to extend into or retract from the ring body to change the size of the wearing hole; the adjustment band having a plurality of positioning portions spaced apart along its length; and a locking mechanism movably disposed on the ring body and capable of radial movement along the ring body, such that the locking mechanism has a locked state and an unlocked state; wherein, when the locking mechanism is in the unlocked state, the adjustment band is movable along the receiving channel; when the locking mechanism is in the locked state, the locking mechanism engages with the positioning portions to restrict the movement of the adjustment band relative to the ring body, thereby maintaining the wearing hole at a corresponding size.

[0007] In some embodiments of this application, at least one end of the adjustment band is provided with an anti-slip portion, the size of which is larger than the opening size of the receiving channel, so as to prevent the adjustment band from completely detaching from the ring body.

[0008] In some embodiments of this application, the positioning part is a boss provided on the side of the adjustment belt, and the bosses are equally spaced along the length direction of the adjustment belt; a groove is formed between adjacent bosses.

[0009] In some embodiments of this application, the positioning part is disposed on the inner side of the adjustment band facing the ring body, and / or the positioning part is disposed on the outer side of the adjustment band away from the ring body.

[0010] In some embodiments of this application, the adjustment band is made of a skin-friendly, hypoallergenic, and flexible material.

[0011] In some embodiments of this application, the locking mechanism includes a locking member and an elastic member; the locking member is movably disposed within the ring body, one end of the locking member extends out of the outer surface of the ring body, and the other end of the locking member extends into the receiving channel and is used to engage with the positioning part; when the locking member is subjected to external force, the locking member disengages from the positioning part to allow the adjusting band to move along the receiving channel; the elastic member is disposed between the locking member and the ring body and is used to drive the locking member to reset so that the locking member remains engaged with the positioning part.

[0012] In some embodiments of this application, the locking member includes a button and a buckle. One end of the button extends out of the outer surface of the ring body, and the other end of the button is connected to the buckle in a driving connection. The buckle extends into the receiving channel and engages with the positioning part. When the button is pressed, the button drives the buckle to move away from the positioning part, thereby releasing the engagement between the buckle and the positioning part.

[0013] In some embodiments of this application, the ring body includes an annular shell and a detection component disposed within the annular shell, the detection component being used to detect the user's physiological data.

[0014] In some embodiments of this application, the detection component includes an arc-shaped battery disposed within the annular housing, a main circuit board electrically connected to the arc-shaped battery, and a plurality of first sensors disposed on the inner side of the annular housing, wherein the first sensors are electrically connected to the main circuit board.

[0015] In some embodiments of this application, the adjustment band is provided with a secondary circuit board and a second sensor. The second sensor is disposed on the side of the adjustment band facing the wearing hole and is electrically connected to the secondary circuit board. The secondary circuit board is electrically connected to the main circuit board through a flexible connector.

[0016] As can be seen from the above technical solution, the beneficial effects of the present invention are as follows:

[0017] This embodiment provides a smart ring. A circumferentially extending receiving channel is provided on the ring body, along with an adjustable band that can move along the receiving channel. The adjustable band can extend into or retract from the ring body, thereby adjusting the size of the wearing hole. Simultaneously, a locking mechanism, in cooperation with multiple positioning parts on the adjustable band, engages with the corresponding positioning parts after adjustment to the target size, reliably locking the adjustable band and ensuring the wearing hole remains stably at the corresponding size. This allows the same smart ring to fit fingers of different sizes and adjust according to changes in finger size under different usage scenarios, improving the smart ring's adaptability and wearing comfort. The locking mechanism prevents the adjustable band from accidentally moving due to external forces during wear, ensuring a stable fit between the smart ring and the finger. This improves the stability and accuracy of physiological data detection, further enhancing the user experience. Attached Figure Description

If the description of the positions of these elements changes, these directional indications also change accordingly.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] Please see Figures 1 to 6 This embodiment provides a smart ring 100, which includes a ring body 10, an adjustment band 20, and a locking mechanism 30.

[0029] The ring body 10 has a circumferentially extending receiving channel 12. An adjusting band 20 is connected to the ring body 10 at both ends, forming a wearing hole for the finger to pass through. The adjusting band 20 can move along the receiving channel 12 to insert into or retract from the ring body 10, thereby changing the size of the wearing hole; the adjusting band 20 has multiple positioning portions 23 spaced apart along its length. A locking mechanism 30 is movably disposed on the ring body 10 and can move radially along the ring body 10, allowing the locking mechanism 30 to have locked and unlocked states. When the locking mechanism 30 is in the unlocked state, the adjusting band 20 can move along the receiving channel 12; when the locking mechanism 30 is in the locked state, the locking mechanism 30 engages with the positioning portions 23 to restrict the movement of the adjusting band 20 relative to the ring body 10, thereby maintaining the wearing hole at the corresponding size.

[0030] Specifically, the ring body 10 is the main structure of the smart ring 100. Its interior can house electronic components such as batteries, control circuit boards, sensors, and wireless communication modules to achieve intelligent functions such as blood oxygen detection, heart rate detection, sleep monitoring, exercise recording, and NFC communication. The ring body 10 has a circumferentially extending receiving channel 12, which is formed inside the ring body 10 and extends along its circumference.

[0031] In some examples, the receiving channel 12 can extend through both ends of the ring body 10, and both ends of the adjustment band 20 can slide along the receiving channel 12. Of course, the receiving channel 12 can also be a semi-closed structure, so that one end of the adjustment band 20 can move along the receiving channel 12, and the other end is directly fixed to the ring body 10, so as to form a wearing hole for the user's finger to pass through together with the ring body 10.

[0032] When the adjustment band 20 extends into the ring body 10, the length of the adjustment band 20 located outside the ring body 10 decreases, and the inner diameter of the wearing hole decreases accordingly. When the adjustment band 20 retracts from the ring body 10, the length of the adjustment band 20 located outside the ring body 10 increases, and the inner diameter of the wearing hole increases accordingly. Therefore, users can adjust the size of the wearing hole according to different finger sizes or wearing needs, allowing the smart ring 100 to fit fingers of different sizes and improving the product's applicability.

[0033] To fix the position of the adjustment band 20, the adjustment band 20 is provided with multiple positioning parts 23 spaced apart along its length. These positioning parts 23 can be arranged sequentially at the same or different intervals to correspond to multiple different wearing sizes. The locking mechanism 30 is movably mounted on the ring body 10 and can move radially along the ring body 10, i.e., it can move toward or away from the adjustment band 20, allowing the locking mechanism 30 to lock or unlock the adjustment band 20.

[0034] When the locking mechanism 30 is in the unlocked state, the locking mechanism 30 disengages from the positioning part 23 on the adjustment band 20. At this time, the adjustment band 20 can slide freely along the receiving channel 12, and the user can adjust the size of the wearing hole according to actual needs.

[0035] Once the adjustment band 20 has moved to the desired position, the locking mechanism 30 switches from the unlocked state to the locked state. The locking mechanism 30 moves radially along the ring body 10 and engages with the positioning part 23 at the corresponding position. Because the locking mechanism 30 restricts the movement of the adjustment band 20 along the receiving channel 12, the adjustment band 20 cannot continue to shift, thus keeping the wearing hole at the corresponding size. This prevents changes in size due to external forces during wearing and improves wearing stability.

[0036] Understandably, the locking mechanism 30 can switch between the locked and unlocked states by pressing, sliding, turning, tossing, rotating, etc.

[0037] This embodiment utilizes the receiving channel 12 located within the ring body 10 to retract and extend the adjustment band 20, and uses the locking mechanism 30 and the positioning part 23 to lock the size, enabling the smart ring 100 to fit fingers of different sizes. This solves the problem of fixed size and poor adaptability of traditional smart rings 100, while ensuring that the adjusted size can be reliably maintained, thus improving the wearing comfort and versatility of the product.

[0038] Please see Figure 1 and Figure 2 In some embodiments, the ring body 10 includes an annular housing 11 and a detection component disposed within the annular housing 11, the detection component being used to detect the user's physiological data. Further, the detection component includes an arc-shaped battery 14 disposed within the annular housing 11, a main circuit board 13 electrically connected to the arc-shaped battery 14, and a plurality of first sensors 15 disposed on the inner side of the annular housing 11, the first sensors 15 being electrically connected to the main circuit board 13.

[0039] Specifically, the annular shell 11 is the main support structure of the smart ring 100, used to install the detection components and other electronic components, and together with the adjustment band 20, it forms a wearing hole for the user's finger to pass through. The annular shell 11 can be made of metal, polymer, or composite materials, such as stainless steel, titanium alloy, aluminum alloy, zirconia ceramic, etc., to balance structural strength, wearing comfort, and product appearance.

[0040] To accommodate the adjustment band 20, the annular housing 11 is not a completely closed circular structure, but rather a non-closed annular structure. For example, the annular housing 11 can be a semi-circular structure, a three-quarters ring structure, a two-thirds ring structure, or other arc-shaped structures with openings. The two ends of the openings are connected to the adjustment band 20, and the adjustment band 20 completes the enclosure of the remaining annular structure, thereby forming a complete wearing hole.

[0041] The detection assembly is housed inside the annular housing 11 and includes an arc-shaped battery 14, a main circuit board 13, and multiple first sensors 15. The arc-shaped battery 14 is adapted to the arc-shaped structure of the annular housing 11, arranged in an arc shape, and extends circumferentially along the annular housing 11. This allows for full utilization of the limited installation space inside the annular housing 11, reducing the overall thickness while ensuring battery life. The arc-shaped battery 14 is electrically connected to the main circuit board 13, providing power to the entire detection assembly.

[0042] The main circuit board 13 is located inside the annular housing 11 and is fixedly connected to the arc-shaped battery 14. The main circuit board 13 is used to control the various first sensors 15 to collect data and to analyze, process, and store the collected physiological data. At the same time, the main circuit board 13 can also be connected to electronic devices such as wireless communication modules, storage modules, and vibration reminder modules to realize the various functions of the smart ring 100.

[0043] Multiple first sensors 15 are disposed on the side of the annular housing 11 facing the wearing hole, i.e., on the inner surface of the annular housing 11. When the user wears the smart ring 100, the first sensors 15 can directly contact or be positioned close to the user's finger skin to improve detection accuracy. The multiple first sensors 15 can be arranged circumferentially along the inner surface of the annular housing 11 to correspond to locations with abundant blood vessels in the human body, thereby improving the quality of physiological signal acquisition.

[0044] In some embodiments, the number and location of the first sensors 15 can be arranged at different positions on the inner side of the annular housing 11 according to different detection requirements, as long as the detection requirements are met. The first sensors 15 may include one or more of the following: heart rate sensor, blood oxygen sensor, body temperature sensor, pressure sensor, photoelectric sensor, bioelectric sensor, or other sensors used for detecting human physiological parameters. This enables intelligent health monitoring functions.

[0045] It should be understood that the thickness of the ring body 10 is only slightly greater than the thickness of the adjustment band 20, so that the boundary between the adjustment band 20 and the ring body 10 forms a relatively smooth transition, thereby ensuring the overall appearance harmony of the smart ring 100 and reducing the feeling of protrusion or foreign objects when wearing it, thus improving the user's wearing comfort.

[0046] Please see Figure 3 and Figure 4 In some embodiments, the adjustment band 20 is made of a skin-friendly, hypoallergenic, flexible material.

[0047] Specifically, the smart ring 100 is an electronic product worn close to the body for extended periods. The adjustment band 20 typically comes into direct contact with the user's finger skin. Therefore, using skin-friendly and hypoallergenic materials can reduce the probability of skin irritation and allergic reactions, thus improving wearing comfort. Since the adjustment band 20 needs to move repeatedly along the receiving channel 12 on the ring body 10 to adjust the size of the wearing hole, it also needs to be made of a material with a certain degree of flexibility.

[0048] In some embodiments, the adjustment belt 20 may be made of one of the flexible polymer materials such as medical-grade silicone, thermoplastic polyurethane elastomer (TPU), thermoplastic elastomer (TPE), and thermoplastic vulcanizate (TPV), or it may be made of a composite of two or more of the above materials.

[0049] For example, the adjustment band 20 can be made of medical-grade liquid silicone, which has good flexibility, aging resistance and sweat corrosion resistance, and can maintain good mechanical properties during long-term wear, and is not prone to hardening, cracking or deformation.

[0050] Please see Figure 3 and Figure 4 In some embodiments, at least one end of the adjustment band 20 is provided with an anti-slip portion 21, the size of which is larger than the opening size of the receiving channel 12, so as to prevent the adjustment band 20 from completely detaching from the ring body 10.

[0051] Specifically, one end of the adjusting band 20 is provided with an anti-slip part 21, and the other end of the adjusting band 20 is provided with a fixing part 22. The fixing part 22 is fixedly connected to the end face of the annular shell 11, while the anti-slip part 21 is movably disposed within the receiving channel 12. The external dimensions of the anti-slip part 21 are larger than the opening size of the receiving channel 12. When the adjusting band 20 moves along the receiving channel 12, the anti-slip part 21 can move with the adjusting band 20 inside the receiving channel 12. However, when the anti-slip part 21 moves to the opening position of the receiving channel 12, because the size of the anti-slip part 21 is larger than the opening of the receiving channel 12, the anti-slip part 21 cannot pass through the opening, thus axially limiting the adjusting band 20 and preventing the adjusting band 20 from completely detaching from the ring body 10.

[0052] In some embodiments, the anti-detachment part 21 can be a ball head structure, a cylindrical head structure, a flange structure, a widening block structure, a stop block structure, or other protruding structures that can form a limiting effect, as long as they can achieve the anti-detachment limiting function.

[0053] In some embodiments, both ends of the adjustment belt 20 can be configured as anti-slip portions 21. In this case, both ends of the adjustment belt 20 can move within the receiving channel 12, thereby realizing the adjustment of both ends of the adjustment belt 20.

[0054] Please see Figure 3 and Figure 4 In some embodiments, the positioning part 23 is a boss provided on the side of the adjusting belt 20, and the bosses are provided at equal intervals along the length direction of the adjusting belt 20; a groove is formed between adjacent bosses.

[0055] Specifically, the boss can be integrally injection molded with the adjusting belt 20, or it can be set on the side of the adjusting belt 20 by secondary molding, bonding or other fixing methods. The boss can be rectangular, hemispherical, trapezoidal or other protruding structures.

[0056] Multiple protrusions are arranged at equal intervals along the length of the adjustment band 20, with a slot formed between two adjacent protrusions. Each slot corresponds to a size adjustment position. When the user adjusts the adjustment band 20, the locking mechanism 30 can sequentially pass over each protrusion and finally engage with the corresponding slot, thus locking the adjustment band 20 in place. Because the spacing between the protrusions is the same, the adjustment amount between two adjacent slots remains consistent, allowing the size of the wearing hole to be adjusted according to a fixed step, thereby improving the accuracy of size adjustment.

[0057] By designing the positioning part 23 as multiple bosses evenly spaced along its length, and utilizing the slots formed between adjacent bosses as locking positions, the adjustment band 20 not only has multiple stable size adjustment levels, but also boasts a simple structure and convenient manufacturing, eliminating the need to machine multiple through holes in the adjustment band 20 to achieve the positioning function. Simultaneously, the continuous positioning structure formed between the bosses and slots provides clear feedback on the adjustment level during the locking mechanism 30, improving the user's operational feel and positioning accuracy. Furthermore, the evenly spaced bosses ensure consistent changes in size with each adjustment, allowing the smart ring 100 to fit fingers of different sizes, enhancing the product's versatility and wearing comfort.

[0058] Please see Figure 1 and Figure 2 In some embodiments, the positioning part 23 is disposed on the inner side of the adjustment band 20 facing the ring body 10, and / or the positioning part 23 is disposed on the outer side of the adjustment band 20 away from the ring body 10.

[0059] Specifically, such as Figure 1 and Figure 5 As shown, the positioning part 23 can be disposed on the inner side of the adjustment band 20, that is, the positioning part 23 is positioned facing the ring body 10. At this time, the outer side of the adjustment band 20 can remain flat, which helps to improve the overall appearance consistency of the smart ring 100. At the same time, the inner side of the adjustment band 20 itself is in contact with the user's finger skin. The positioning part 23 adopts a spaced-out protrusion structure, which not only satisfies the locking and positioning function, but also increases the contact friction between the adjustment band 20 and the finger, thus playing a role in preventing slippage. When the user wears the smart ring 100 for exercise, sweating, or daily activities, it can reduce the slippage of the smart ring 100 along the finger axis or circumference, improving wearing stability. In addition, since the positioning part 23 also has the function of anti-slip texture, there is no need to set up a separate anti-slip structure, which helps to simplify the overall structure of the adjustment band 20.

[0060] like Figure 2 and Figure 6As shown, the positioning part 23 can also be located on the outer side of the adjustment band 20, that is, the positioning part 23 is positioned away from the ring body 10. In this case, the side of the adjustment band 20 that contacts the user's finger can remain smooth and flat, which can prevent the positioning part 23 from causing local pressure marks or foreign body sensation due to long-term contact with the skin. At the same time, since the positioning part 23 is located on the outside of the adjustment band 20, the locking mechanism 30 can directly cooperate with the positioning part 23 to achieve locking without passing through the receiving channel 12, thereby facilitating the installation and maintenance of the locking mechanism 30.

[0061] Please see Figures 1 to 6 In some embodiments, the locking mechanism 30 includes a locking member and an elastic member. The locking member is movably disposed within the ring body 10, with one end extending beyond the outer surface of the ring body 10 and the other end extending into the receiving channel 12 and engaging with the positioning part 23. When the locking member is subjected to external force, the locking member disengages from the positioning part 23, allowing the adjusting band 20 to move along the receiving channel 12. The elastic member is disposed between the locking member and the ring body 10 and is used to drive the locking member to reset, so that the locking member remains engaged with the positioning part 23.

[0062] Furthermore, the locking element includes a button 311 and a latch 312. One end of the button 311 extends out of the outer surface of the ring body 10, and the other end of the button 311 is connected to the latch 312. The latch 312 extends into the receiving channel 12 and engages with the positioning part 23. When the button 311 is pressed, the button 311 moves the latch 312 away from the positioning part 23 to release the engagement between the latch 312 and the positioning part 23.

[0063] Specifically, the locking element includes a button 311 and a latch 312. The button 311 is disposed inside the ring body 10 and can reciprocate along the radial direction of the ring body 10. One end of the button 311 extends out of the outer surface of the ring body 10 for the user to press; the other end of the button 311 is located inside the ring body 10 and is connected to the latch 312, so that the button 311 and the latch 312 can move synchronously.

[0064] The buckle 312 is located on one side of the receiving channel 12. One end of it is connected to the button 311, and the other end extends into the receiving channel 12, where it can engage with the positioning part 23 on the adjusting band 20. In this embodiment, the elastic element can be a compression spring, leaf spring, or other structure with elastic recovery capability. The elastic element can be sleeved on the outer periphery of the button 311, or disposed between the button 311 and the ring body 10, or disposed between the buckle 312 and the ring body 10. When the button 311 is not subjected to external force, under the elastic force of the elastic element, the button 311 always moves towards the outside of the ring body 10, and the buckle 312 continues to extend into the receiving channel 12 and remains engaged with the positioning part 23.

[0065] When the user needs to adjust the size of the smart ring 100, they simply press button 311. Under external force, button 311 moves radially inward along the ring body 10, simultaneously causing the buckle 312 to move away from the adjustment band 20. This gradually disengages the buckle 312 from the slot between the positioning parts 23, thus releasing the contact between the buckle 312 and the positioning parts 23. At this time, the adjustment band 20 can slide freely along the receiving channel 12. The user can push the adjustment band 20 inward or pull it outward according to the size of their finger to change the size of the wearing hole.

[0066] Once the adjustment band 20 has moved to the desired position, the user releases button 311. The elastic element releases its elastic restoring force, pushing button 311 back to its original position in the opposite direction, and causing the buckle 312 to move back toward the adjustment band 20. When the buckle 312 moves to the corresponding position, it re-enters the slot between the adjacent positioning parts 23, locking again and thus limiting the further movement of the adjustment band 20, keeping the wearing hole at the current adjustment size.

[0067] By adopting the above-mentioned locking mechanism 30, not only can the locking and unlocking of the adjusting belt 20 be reliably realized, but the entire locking process is also automatically completed by the elastic element, without complicated operation, and the structure is simple and highly reliable.

[0068] Of course, in some other embodiments, the locking mechanism 30 may not have an elastic element, but instead uses a sliding button 311 with a self-locking function. The button 311 is slidably disposed on the annular housing 11 and has a first locking position and a second locking position. When the button 311 slides to the first locking position, the button 311 drives the buckle 312 away from the adjusting belt 20, causing the buckle 312 to disengage from the positioning part 23, and the adjusting belt 20 can move freely along the telescopic channel; when the button 311 slides to the second locking position, the button 311 drives the buckle 312 to move towards the adjusting belt 20, causing the buckle 312 to re-engage into the slot formed between the two adjacent positioning parts 23, locking the adjusting belt 20. Since the button 311 can remain in the corresponding locking position, the switching between the locking and unlocking states can be achieved without the need for an elastic element.

[0069] Please see Figure 5 and Figure 6 In some embodiments, the adjustment band 20 includes a secondary circuit board 24 and a second sensor 25. The second sensor 25 is located on the side of the adjustment band 20 facing the wearing hole and is electrically connected to the secondary circuit board 24; the secondary circuit board 24 is electrically connected to the main circuit board 13 via a flexible connector.

[0070] Specifically, a flexible sub-circuit board 24 is provided inside the adjustment belt 20. The sub-circuit board 24 can be embedded in the middle of the adjustment belt 20, or it can be encapsulated inside the adjustment belt 20 by means of overmolding, secondary injection molding, etc., so as to avoid the influence of sweat, water vapor and external collisions and improve the overall reliability.

[0071] The flexible connector can be a flexible printed circuit board (FPC), a flexible ribbon cable, or a flexible conductive strip. The flexible connector can be located at one end of the fixing part 22 of the adjusting belt 20. One end of the flexible connector is electrically connected to the main circuit board 13, and the other end is electrically connected to the sub-circuit board 24. It can bend as the adjusting belt 20 extends and retracts, thereby ensuring that the sub-circuit board 24 and the main circuit board 13 maintain a stable electrical connection regardless of the size of the adjusting belt 20, and that the normal operation of the detection component is not affected by size adjustments.

[0072] A second sensor 25 is provided on the adjustment band 20, and the second sensor 25 is located on the side of the adjustment band 20 facing the wearing hole, that is, the second sensor 25 is facing the user's finger. When the user wears the smart ring 100, the second sensor 25 can directly contact or be close to the skin of the finger to collect human physiological signals. The second sensor 25 can also be a blood oxygen sensor, heart rate sensor, body temperature sensor, or skin conductance sensor, and its specific type can be configured according to the functional requirements of the smart ring 100.

[0073] One or more second sensors 25 can be provided. Multiple second sensors 25 can be arranged at intervals along the length of the adjustment belt 20, or they can be concentrated in the middle of the adjustment belt 20 in an area with a large contact area with the finger, thereby expanding the range of physiological signal acquisition and improving detection accuracy and stability.

[0074] Since the adjustment band 20 can be stretched and adjusted according to the user's finger size, the second sensor 25 set on the adjustment band 20 can automatically adjust its contact position with the finger as the position of the adjustment band 20 changes, so that the second sensor 25 is always kept near a suitable detection position. There is no need to design sensor installation positions separately for smart rings 100 of different sizes, thereby improving the adaptability of smart rings 100 to users with different finger sizes and further improving the detection effect and user experience during long-term wear.

[0075] In summary, this embodiment provides a smart ring 100. By providing a circumferentially extending receiving channel 12 on the ring body 10 and an adjustment band 20 movable along the receiving channel 12, the adjustment band 20 can extend into or retract from the ring body 10, thereby adjusting the size of the wearing hole. Simultaneously, by providing a locking mechanism 30 that cooperates with multiple positioning parts 23 on the adjustment band 20, after adjustment to the target size, the locking mechanism 30 can engage with the corresponding positioning part 23 to reliably lock the adjustment band 20, ensuring the wearing hole remains stably at the corresponding size. Therefore, the same smart ring 100 can adapt to fingers of different sizes and can be adjusted according to changes in finger size under different usage scenarios, improving the adaptability and wearing comfort of the smart ring 100. Furthermore, the locking mechanism 30 prevents the adjustment band 20 from accidentally moving due to external forces during wear, ensuring a stable fit between the smart ring 100 and the finger, which is beneficial for improving the stability and accuracy of physiological data detection, further enhancing the user experience.
