[0051] Smart rings are an emerging type of smart wearable device that has recently gained popularity. Unlike traditional rings, smart rings offer various electronic functions and can be flexibly designed in terms of form to meet specific needs. They integrate traditional ring technology with smart technology, providing users with more functionality and convenience. To further enhance the user experience of smart rings and meet users' personalized needs, offering diverse appearances, the design of smart ring forms is necessary.

[0052] Therefore, this invention proposes a smart ring that aims to provide users with a completely new ring design through a detachable mechanism. Users can choose different materials, colors, and textures for the outer ring according to their personality and fashion style, showcasing their personal taste and unique charm.

[0053] Reference Figures 1 to 3 In one embodiment of the present invention, the smart ring 100 includes an outer ring shell 200, an inner ring shell 300, and a conversion structure 800. The conversion structure 800 is disposed between the inner ring shell 300 and the outer ring shell 200. The inner ring shell 300 has a stacked position that overlaps with the outer ring shell 200 and an interleaved position that is misaligned. In the stacked position, the outer ring shell 200 and the inner ring shell 300 are stacked in the radial direction. In the interleaved position, the outer ring shell 200 and the inner ring shell 300 are at least partially misaligned and separated in the radial direction.

[0054] Combination Figures 4 to 7 Specifically, the smart ring 100 has a first wearing state in which the outer ring shell 200 and the inner ring shell 300 are stacked together in the radial direction, and a second wearing state in which the inner ring shell 300 and the outer ring shell 200 are at least partially misaligned and separated in the radial direction. For example, after wearing the smart ring 100, the user can change the inner ring shell 300 and the outer ring shell 200 from being stacked to being separated, thereby switching from the first wearing state to the second wearing state, meeting the user's personalized needs and providing a variety of appearance smart rings 100.

[0055] Specifically, the smart ring 100 is worn on the user's finger. The smart ring 100 can be decorated with ornaments, such as jewelry or cartoon shapes and other structural components. Understandably, the smart ring 100 can also include software / hardware components for human-computer interaction, such as a display screen, which can realize heart rate measurement, blood oxygen measurement, etc. after being worn.

[0056] Reference Figures 6 to 12 To facilitate wearing and removing the smart ring, the smart ring 100 specifically includes a conversion structure 800. This conversion structure 800 is located between the inner ring shell 300 and the outer ring shell 200. The first shell 370 and the second shell 380 are connected by an elastic element 400, allowing for both a spliced ​​state and a separated state where the inner diameter of the inner ring shell 300 is expanded. The conversion structure 800 enables the first shell 370 and the second shell 380 to switch between these states. Understandably, the maximum inner diameter of the outer ring shell 200 is the maximum outer diameter of the inner ring shell 300. If the inner diameter of the inner ring shell 300 can change, then it becomes easier for the user to wear and remove the ring. The structure of the first shell 370 and the second shell 380 opening or closing under the pushing force of the elastic element 400 allows the inner diameter of the inner ring shell 300 to increase or decrease, satisfying the needs of both using the smart ring 100 and removing it, while also providing the user with a completely new wearing and removing experience.

[0057] In one embodiment, the conversion structure 800 is provided as an inner protrusion and an outer protrusion in the inner ring shell 300 or the outer ring shell 200, or a combination of a spring ball and a groove. Taking the inner protrusion and outer protrusion combination as an example, when the inner ring shell 300 is placed inside the outer ring shell 200, the inner protrusion and outer protrusion abut against each other, so that the first shell 370 and the second shell 380 are pressed against the elastic element 400 and spliced ​​on the outer ring shell 200. At this time, the inner diameter of the spliced ​​first shell 370 and the second shell 380 is the smallest, and the user wears it most stably. After the inner ring shell 300 and the outer ring shell 200 are separated, the inner protrusion and outer protrusion separate, and the first shell 370 and the second shell 380 are separated under the action of the elastic element 400 between them, so that the inner diameter of the first shell 370 and the second shell 380 increases, making it easier for the user to take them off.

[0058] Reference Figure 8 In this embodiment, the conversion structure 800 includes a first inclined surface 810 on the outer surface of the inner ring shell 300 and a second inclined surface 820 on the inner surface of the outer ring shell 200. The first inclined surface 810 is inclined along the embedding direction, and the second inclined surface 820 is inclined in the opposite direction to the first inclined surface 810. The first inclined surface 810 and the second inclined surface 820 slide against each other, so that the first shell 370 and the second shell 380 can be converted between a separated state and a spliced ​​state. When the inner ring shell 300 is placed on the outer ring shell 200, the cross-section of the mating position of the first inclined surface 810 and the second inclined surface 820 is rectangular, and the overlapping position of the first inclined surface 810 and the second inclined surface 820 is the diagonal of the rectangle. The inner diameter of the outer ring shell 200 gradually decreases in the width direction. Thus, after the inner ring shell 300 is inserted into the outer ring shell 200, it will gradually become smaller, and after splicing, it will reach the maximum limit, which is also the position where the inner diameter of the inner ring shell 300 is the smallest. When the inner ring shell 300 is separated from the outer ring shell 200, because the inner diameter of the outer ring shell 200 increases, the first shell 370 and the second shell 380 are separated from each other by the action of the elastic element 400. The inner diameter of the inner ring shell 300 formed by the first shell 370 and the second shell 380 increases, making it easier for the user to take off the smart ring 100.

[0059] In one embodiment, the elastic element 400 is a spring sheet, with its two ends connected to the first housing 370 and the second housing 380, respectively; in another embodiment, the elastic element 400 is a rubber block; see reference. Figure 11 and Figure 12In this embodiment, the elastic element 400 is a compression spring. To facilitate the installation of the compression spring and to ensure the stability of the compression spring's force during subsequent splicing and separation of the first housing 370 and the second housing 380, grooves 350 are provided on the splicing end faces of the first housing 370 and the second housing 380. The two ends of the compression spring are respectively placed in the grooves 350 of the first housing 370 and the second housing 380. During the separation of the first housing 370 and the second housing 380, part of the compression spring is exposed. When the first housing 370 and the second housing 380 are spliced, the compression spring is located in the space after the splicing of the grooves 350 of the first housing 370 and the second housing 380. The setting of the first inclined surface 810 and the second inclined surface 820 allows the inner ring shell 300 and the outer ring shell 200 to fit together, so that from the appearance, the dividing gap between the inner ring shell 300 and the outer ring shell 200 is small, resulting in good product quality and appearance.

[0060] Reference Figures 13 to 17 If the inner ring shell 300 can be completely detached from the outer ring shell 200, it may cause damage to the product in certain situations. For example, when a user wears the smart ring 100 on their finger, the relative rotation between the inner ring shell 300 and the outer ring shell 200 may cause the flexible circuit board 600 between the inner ring shell 300 and the outer ring shell 200 to twist. This may also increase the preload between the inner ring shell 300 and the outer ring shell 200, making it more difficult to remove. Therefore, the smart ring 100 also includes a limiting structure 840, which is located between the inner ring shell 300 and the outer ring shell 200. The inner ring shell 300 has a stacked position and a staggered position with the outer ring shell 200. The limiting structure 840 is used to limit the position at the stacked position and the staggered position.

[0061] Specifically, in addition to guiding the movement of the inner ring shell 300 and the outer ring shell 200, the limiting structure 840 also has a certain limiting function, restricting the rotation of the inner ring shell 300 relative to the outer ring shell 200 in the circumferential direction. In one embodiment, the limiting structure 840 is composed of ribs. For example, the inner surface of the outer ring shell 200 is provided with two spaced ribs that extend along the width direction, and the outer surface of the inner ring shell 300 is provided with one rib located between the two ribs of the outer ring shell 200. In this embodiment, the limiting structure 840 includes a sliding groove 841 provided in the inner ring shell 300 and a sliding shaft 842 provided in the outer ring shell 200. The sliding shaft 842 is placed in the sliding groove 841, and the sliding groove 841 extends along the embedding direction of the inner ring shell 300.

[0062] Specifically, the sliding groove 841 includes two sliding shafts 842, which are arranged corresponding to the number of sliding grooves 841. The two sliding grooves 841 are respectively provided in the first housing 370 and the second housing 380, and one sliding groove 841 cooperates with one sliding shaft 842. Understandably, the inner ring shell 300 is separably spliced ​​through the first housing 370 and the second housing 380. The corresponding arrangement of the sliding grooves 841 and the sliding shafts 842 in the first housing 370 and the second housing 380 allows for smoother separation and installation processes. In a specific design, to ensure the installation of the sliding shafts 842 and to prevent the sliding shafts 842 and the sliding grooves 841 from affecting the fit of the first inclined surface 810 and the second inclined surface 820, the outer ring shell 200 is provided with two mounting protrusions 220 at the end of the inner ring shell 300 in the embedding direction. The inner ring shell 300 is provided with a clearance groove 320, and a partition wall 340 is provided between the two clearance grooves 320. The sliding groove 841 is provided on the partition wall 340, and the sliding shaft 842 is inserted into the two mounting protrusions 220 and placed in the sliding groove 841. The mounting protrusions 220 are placed in the relief groove 320. In this way, when the inner ring shell 300 and the outer ring shell 200 are separated, the sliding shaft 842 moves in the sliding groove 841 and the mounting protrusions 220 move in the relief groove 320. When the first shell 370 and the second shell 380 are separated from the outer ring shell 200, the sliding shaft 842 and the sliding groove 841 will restrict the separation of the first shell 370 and the second shell 380, and will not block the expansion of the inner diameter of the first shell 370 and the second shell 380.

[0063] To facilitate the installation of the second sub-plate 612, the second sub-plate 612 is further divided into two sections at the position of the slide groove 841 of the second housing 380, thereby avoiding the position of the slide groove 841, and is installed at both ends of the slide groove 841 of the second housing 380, which facilitates the installation of the second sub-plate 612.

[0064] Combination Figures 10 to 12When worn, the user pushes the inner ring shell 300 out of the outer ring shell 200. The first shell 370 and the second shell 380 move along the slide groove 841 and the slide shaft 842. Due to the setting of the first inclined surface 810 and the second inclined surface 820, the first shell 370 and the second shell 380 are limited when they move to the end of the slide groove 841 and will not detach from the outer ring shell 200. Under the action of the upper and lower compression springs, the first shell 370 and the second shell 380 separate, and the inner diameter of the first shell 370 and the second shell 380 expands. Here, it should be noted that the first... The first housing 370 and the second housing 380 can be connected by a folding strap or a flexible strap. Because the inner diameter of the inner ring housing 300 is enlarged, the user can more easily put the inner ring housing 300 on the finger, and then push the outer ring housing 200 in the opposite direction to the inner ring housing 300. Under the action of the first inclined surface 810 and the second inclined surface 820, the first housing 370 and the second housing 380 are spliced ​​together, which reduces the inner diameter. This makes it easier for the inner ring housing 300 to fit the finger, and the electrodes of the first housing 370 and the second housing 380 can also fit tightly against the skin of the finger, thereby measuring the body's health data and making the wearing more secure.

[0065] The inner ring shell 300 fits tightly against the surface of the user's finger under the action of the outer ring shell 200. During the process of removing the ring, the inner ring shell 300 may be too tightly engaged. If too much force is applied, the outer ring shell 200 may detach too abruptly, pulling on the flexible circuit board 600 between the inner and outer ring shells. The sliding groove 841 and sliding shaft 842 are designed to prevent the user from damaging the flexible circuit board 600 by applying too much force when removing the smart ring 100. That is, when the outer ring shell 200 moves out of the inner ring shell 300, the first shell 370 and the second shell 380 separate; when the outer ring shell 200 is fitted onto the inner ring shell 300, the first shell 370 and the second shell 380 are joined together. During this process, the bendable plate part 620 is shaped like a 7, the bendable FPC is at its maximum bending radius, and it is positioned in the middle of the inner and outer shells. As the outer ring shell 200 gradually slides open, the second plate portion 630 and the bendable plate portion 620 slide together with the outer ring shell 200 for a certain distance. During this time, the bending angle and shape of the bendable plate portion 620 change accordingly, ensuring that the first plate portion 610 and the second plate portion 630 remain unobstructed connected through the bendable plate portion 620 while the inner ring shell 300 and the outer ring shell 200 are separated.

[0066] Reference Figures 13 to 17For ease of wearing or removing, the smart ring 100 also includes a flexible buckle 850. The flexible buckle 850 is installed in the inner ring shell 300, and the inner ring shell 300 has a slot 330 that passes through the sliding groove 841. At least a portion of the flexible buckle 850 is placed in the sliding groove 841 from the slot 330. The flexible buckle 850 is used to limit the movement of the sliding shaft 842. The end of the flexible buckle 850 is V-shaped and folded. The slot 330 passes through the sliding groove 841, which extends through the thickness direction of the partition wall 340. The slot 330 extends above the partition wall 340 and connects with the sliding groove 841. The V-shaped end of the flexible buckle 850 is placed in the sliding groove 841 and is limited by the V-shaped end of the flexible buckle 850 during the sliding of the sliding shaft 842. It is easy to understand that, under the action of the compression spring, the first shell 370 and the second shell 380 tend to move towards both sides of the outer ring shell 200. Thus, when the inner ring shell 300 and the outer ring shell 200 cooperate with the first inclined surface 810 and the second inclined surface 820, the first shell 370 and the second shell 380, from the spliced ​​state, that is, when the inner shell 370 and the outer ring shell 200 are stacked, tend to move towards the separated state. This may lead to separation during wearing. Therefore, the elastic buckle 850 can limit the inner ring shell 300 in the stacked and separated positions, so that the inner ring shell 300 can play a certain limiting role in the spliced ​​state to ensure the stability of wearing; and the inner ring shell 300 and the outer ring shell 200 can play a certain limiting role in the separated state to facilitate wearing.

[0067] To allow the smart ring 100 to have different limiting positions during detachment or donning, thus meeting the needs of different users, increasing the number of elastic buckles 850 increases the number of positions the outer ring shell 200 can stop at. From a width perspective, there is a height difference between the outer end faces of the inner ring shell 300 and the outer ring shell 200. When the inner ring shell 300 is embedded into the outer ring shell 200, their outer end faces become flush. Understandingly, increasing the number of elastic buckles 850 allows the inner ring shell 300 and the outer ring shell 200 to have different limiting positions. For example, there could be indicator marks on the outside of the inner ring shell 300 and the outer ring shell 200. For instance, when the user moves to the first position, the inner ring shell 300 slightly extends beyond the outer ring shell 200 in width; when moving to the second position, the inner ring shell 300 extends further than in the first position. This helps the user know which position they are in, meeting different usage needs.

[0068] In another embodiment of the present invention, the smart ring 100 further includes a flexible circuit board 600. That is, the smart ring 100 includes an outer ring shell 200, an inner ring shell 300, a limiting structure 800, and a flexible circuit board 600. The limiting structure 800 can be referred to the above description. The inner ring shell 300 is detachably embedded in the outer ring shell 200. The flexible circuit board 600 includes a first plate portion 610, a bendable plate portion 620, and a second plate portion 630 connected in sequence. The first plate portion 610 is embedded in the inner ring shell 300, the second plate portion 630 is connected to the outer ring shell 200, and the bendable plate portion 620 is located between the inner ring shell 300 and the outer ring shell 200.

[0069] A flexible printed circuit board (FPCB) 600 is a circuit board made of a flexible substrate, possessing the characteristics of being bendable, rollable, and foldable. The first board portion 610 and the second board portion 630 are the substrate layer and the component layer, respectively. The substrate layer is the main body of the entire flexible circuit board 600 and is typically made of flexible materials such as polyimide or polyester film. The substrate layer provides flexibility and bending properties, allowing the FPCB to adapt to different usage environments. The component layer is a layer added on the substrate layer using printing technology. These components can be wires, pads, resistors, capacitors, transistors, etc. The design of the component layer is based on the specific circuit function requirements for layout and connection. To protect the component layer and provide good insulation, the flexible circuit board 600 typically has a protective cover layer covering both the top and bottom of the component layer. The protective layer is usually made of polyimide film and is bonded to the substrate layer by adhesives or hot pressing. During assembly, the flexible circuit board 600 needs to be connected to other hardware devices or electronic components. The bendable plate section 620 is typically made of metal foil or conductive tape.

[0070] In order to make the outer ring shell 200 and the inner ring shell 300 fit more tightly, the inner ring shell 300 is provided with a relief groove 310 on the side facing the outer ring shell 200, and the outer ring shell 200 is provided with a mounting groove 210 corresponding to the relief groove 310. The second plate portion 630 is placed in the mounting groove 210, and the bendable plate portion 620 passes through the relief groove 310. After the inner ring shell 300 and the outer ring shell 200 are separated, they are connected by a bendable plate portion 620. The first plate portion 610 is embedded in the inner ring shell 300 and is not visible from the outside. The bendable plate portion 620 passes through the clearance groove 310. On the one hand, it allows the second plate portion 630 to be installed in the outer ring shell 200. The bendable plate portion 620 is located between the inner ring shell 300 and the outer ring shell 200, which facilitates the installation of the bendable plate portion 620. On the other hand, the bendable plate portion 620 is not visible outside the smart ring 100 and does not interfere with the outer ring shell 200 and the inner ring shell 300.

[0071] Combination Figures 6 to 8 For example, the first plate portion 610 is provided with an electrode portion 500, and the inner surface of the inner ring shell 300 is provided with corresponding electrode holes 360. At least a portion of the electrode portion 500 is exposed outside the electrode holes 360 to contact the user's finger and detect the user's health data through electrical signals. The electrode portion 500 is connected to a control module or a flexible circuit board 600 via wires. The electrode portion 500 transmits relevant electrical signals by contacting the surface of the user's finger. For example, a pressure sensing module can be set in the flexible circuit board 600, and the electrode portion 500 can transmit electrical signals so that the pressure sensor module can use the pressure signal of the relative position of the finger. The setting of multiple contact portions further improves the accuracy of the finger pressure signal.

[0072] The electrode unit 500, while collecting finger pressure, can also collect finger health data, thereby expanding the functionality of the smart ring 100 and increasing its applicability. For example, the flexible circuit board 600 also has a Bluetooth chip installed. The Bluetooth chip is electrically connected to the control module to receive finger health data and transmit and share this data with external devices, facilitating the monitoring and tracking of the user's health status.

[0073] Furthermore, a motor is also installed on the flexible circuit board 600. The motor is electrically connected to and controlled by the control module to generate vibrations to the finger. For example, when the user's health data is abnormal, the control module controls the motor to vibrate, so that the finger feels the vibration signal, which can help remind the user to pay attention to the abnormal health data and monitor their health status in a timely manner. Of course, the motor can also be used for other functions, such as monitoring or reminding the user of exercise, etc., which are not limited here.

[0074] To facilitate user operation of the smart ring 100, the smart ring 100 specifically includes a button component 700. A mounting slot 210 penetrates the outer ring shell 200, and the button component 700 is embedded in the mounting slot 210. The button component 700 includes a central button 710 and four circumferential buttons 720 located above, below, left, and right of the central button 710. The second plate 630 has multiple function keys corresponding to the central button 710 and the four circumferential buttons 720. The button component 700 can realize the relevant functions of the smart ring 100. For example, the central button and the circumferential buttons 720 can be trigger buttons, menu buttons, directional pads, function buttons, etc. For example, they can be used to open the application's menu interface, or to access settings, pause, or other functions. The directional pads can be used for navigation or menu selection, and the specific functions of the function keys may vary depending on the device. For example, volume control buttons, power buttons, etc.

[0075] Reference Figure 3 , Figure 5 , Figure 7 , Figure 13 In this design, the button 700 is a five-way button, which differs from the traditional design. It is simple, practical, and suitable for mass production. The second board 630 is a button FPC with five button springs 640 welded on it and fixed inside the outer shell. The five button springs 640 are at the bottom of the button cap. The first board 610 is a function FPC, the second board 630 is a button FPC, and the bendable board 620 connects the two. All three are continuous and share the same flexible circuit board 600. The second board 630 is arranged in the mounting groove 210 of the outer ring shell 200. This way, the button 700 can be used for control whether the inner ring shell 300 and the outer ring shell 200 are in a separate state or spliced ​​state. This not only brings users a brand-new ring shape but also makes it easier for users to operate the smart ring 100. During the triggering process, each button 700 can correspond one-to-one with a button spring 640. After the button is pressed, the button spring 640 is in a tightly compressed state, thereby connecting with the circuit on the second board 630 through the button spring 640 to realize the corresponding function. The button spring 640 acts as a switch.

[0076] Reference Figure 3 To make the installation of the second plate 630 more stable, the smart ring 100 also includes a cover plate 730, which is located in the mounting groove 210 and faces the surface of the inner ring shell 300. This prevents the second plate 630 from detaching and improves stability.

[0077] To facilitate the installation of the FPC, the inner ring shell 300 includes a first shell 370 and a second shell 380 that can be spliced ​​together to form a ring. The first plate portion 610 includes a first sub-plate 611 and a second sub-plate 612 connected and grounded. The first sub-plate 611 is connected to the bendable plate portion 620 and the second plate portion 630. The first sub-plate 611 is placed in the first shell 370, and the clearance groove 310 is provided in the first shell 370. The second sub-plate 612 is placed in the second shell 380. If the first plate 610 uses a ring-shaped FPC, the manufacturing process is more complicated and the installation requirements are higher. Therefore, the inner ring shell 300 is divided into two halves by splicing. That is, both the first shell 370 and the second shell 380 are arc-shaped. The circumference of the arc of the first shell 370 and the second shell 380 can be the same, that is, they are separated in half; or one can be larger and the other smaller. For better appearance, the first shell 370 and the second shell 380 are symmetrically separated. The splicing method of the first shell 370 and the second shell 380 can be to set a snap-fit ​​structure at the arc-shaped ends of the first shell 370 and the arc-shaped ends of the second shell 380, such as a snap-fit ​​protrusion or a snap-fit ​​groove 330, or to use a mutual magnetic adsorption method for splicing and fixing. The first sub-plate 611 and the second sub-plate 612 can be electrically connected by wires.
