[0031] Smart rings, unlike traditional rings, are wearable electronic devices equipped with mobile components such as sensors and NFC chips. They can be used for a variety of applications, primarily for tracking daily activities and as peripherals for mobile devices. Their diverse electronic functions and flexible design options make them a compelling alternative to smartwatches and fitness trackers.

[0032] Currently, the sizes of common smart rings on the market are all fixed. However, different users have fingers of different thicknesses, and fixed-size smart rings are not conducive to user comfort.

[0033] In view of this, the present invention proposes a smart ring.

[0034] Please refer to Figures 1 to 6 In an embodiment of the present invention, the smart ring includes a ring body 100, which includes an open-loop ring portion and an adjustment mechanism 200 provided between the two open-loop ends of the open-loop ring portion. The adjustment mechanism 200 is used to magnetically attract the two open-loop ends of the open-loop ring portion, and the adjustment mechanism 200 includes at least one electromagnet. The smart ring also includes a controller 310 electrically connected to the electromagnet. The controller 310 controls the current flowing in the electromagnet to control the magnitude of the magnetic attraction between the two open-loop ends of the open-loop ring portion, adjusts the distance between the two open-loop ends of the open-loop ring portion, and thereby adjusts the size of the smart ring.

[0035] Specifically, the smart ring includes a ring body 100, which is used to be put on the finger to realize the wearing of the smart ring. Of course, the smart ring can also include decorations provided on the ring body 100, and the decorations can be other structural parts such as jewelry or cartoon shapes. The ring body 100 includes an open-loop ring portion, and the open-loop ring portion extends along its circumference and has two free ends, namely a first end 111 and a second end 112, and an adjustment mechanism 200 is provided between the first end 111 and the second end 112. The adjustment mechanism 200 is used to make the open-loop ends of the open-loop ring portion magnetically attracted to each other, that is, the adjustment mechanism 200 makes the first end 111 and the second end 112 of the open-loop ring portion magnetically attracted to each other. The adjustment mechanism 200 includes at least one electromagnet, which can generate magnetism when energized to generate an interaction force with another magnetic structural part. The smart ring also includes a controller 310, which is electrically connected to the electromagnet and controls the current flowing in the electromagnet, thereby controlling the magnetic attraction between the two ends of the open loop of the open loop ring, thereby adjusting the distance between the first end 111 and the second end 112, thereby adjusting the size of the smart ring to meet the wearing needs of different users, thereby increasing the applicability of the smart ring and improving the comfort of use of the smart ring.

[0036] In one embodiment, the adjustment mechanism 200 includes two electromagnets, both of which are electrically connected to the controller 310. Under the control of the controller 310, the magnitude of the current flowing in the two electromagnets is adjusted, thereby controlling the magnitude of the magnetism between the two electromagnets and the magnitude of the magnetic attraction between the two electromagnets, thereby adjusting the distance between the two ends of the open loop of the open loop ring part to achieve the purpose of adjusting the size of the smart ring.

[0037] In another embodiment, the adjustment mechanism 200 includes an electromagnet and a permanent magnet, wherein the electromagnet is electrically connected to the controller 310. Under the control of the controller 310, the current flowing in the electromagnet can be adjusted, and the magnetism generated by the electromagnet can be adjusted, thereby controlling the magnetic attraction between the electromagnet and the permanent magnet to adjust the distance between the first end 111 and the second end 112, thereby adjusting the size of the smart ring.

[0038] In another embodiment, the adjustment mechanism 200 includes an electromagnet and a magnetic structural member, wherein the material of the magnetic structural member contains at least one of magnetic materials such as iron, cobalt, nickel, etc. The electromagnet is electrically connected to the controller 310. Under the control of the controller 310, the current flowing in the electromagnet can be adjusted, and the magnetism generated by the electromagnet can be adjusted, thereby controlling the size of the magnetic attraction between the electromagnet and the magnetic structural member to adjust the distance between the first end 111 and the second end 112, thereby adjusting the size of the smart ring.

[0039] In one embodiment, the controller 310 includes a main control chip, a battery, and an on / off switch. The battery provides power for the smart ring. The main control chip is electrically connected to the electromagnet and controls the current flowing through the electromagnet, thereby controlling the magnetic attraction between the two ends of the open loop of the ring, adjusting the distance between the first end 111 and the second end 112, and thus adjusting the size of the smart ring. The on / off switch controls the connection between the electromagnet and the main control chip. In other words, the size of the smart ring can be adjusted by turning the on / off switch on and off. Once the size is adjusted to the desired value, the on / off switch can be turned off.

[0040] One technical solution of the present invention involves providing an open-loop ring portion within a smart ring and disposing an adjustment mechanism 200 between the two open ends of the open loop portion. The adjustment mechanism 200 is configured to magnetically attract the two open ends of the open loop portion. The adjustment mechanism 200 comprises at least one electromagnet, which is electrically connected to a controller 310 within the smart ring. The controller 310 controls the current flowing through the electromagnet, thereby controlling the magnetic attraction between the two open ends of the open loop portion. Adjusting the spacing between the two open ends of the open loop portion allows the size of the smart ring to be adjusted to suit different wearers, thereby expanding the range of applications and enhancing the comfort of use. Thus, compared to existing smart rings with fixed sizes, the smart ring of the present invention is adjustable, improving comfort and applicability. Furthermore, compared to other more complex size adjustment mechanisms in the prior art, the present invention utilizes the adjustment mechanism 200, which includes at least one electromagnet, to adjust the size of the smart ring using the magnetic field between the magnets. This simplifies the structure of the smart ring and makes it easier to operate, contributing to its miniaturization and lightweighting.

[0041] Please refer to Figure 2 and Figure 3 Furthermore, the adjustment mechanism 200 includes a first magnet 210 and a second magnet 220 respectively arranged at both ends of the open loop of the open loop ring portion, and an elastic member 230 arranged between the first magnet 210 and the second magnet 220, and at least one of the first magnet 210 and the second magnet 220 is an electromagnet.

[0042] Specifically, the adjustment mechanism 200 includes a first magnet 210, a second magnet 220, and an elastic member 230, wherein the first magnet 210 is mounted on the first end 111 of the open-loop ring portion, and the second magnet 220 is mounted on the second end 112 of the open-loop ring portion. The first magnet 210 and the second magnet 220 can be fixed to the first end 111 and the second end 112, respectively, by bonding or snapping. The elastic member 230 is mounted between the first magnet 210 and the second magnet 220. When a magnetic attraction is generated between the first magnet 210 and the second magnet 220, the elastic member 230 between the two can be compressed or released, thereby adjusting the distance between the first magnet 210 and the second magnet 220 to adjust the size of the smart ring.

[0043] At least one of the first magnet 210 and the second magnet 220 is an electromagnet. When energized, the electromagnet generates magnetism, generating an interaction force with the other magnet. The controller 310 is electrically connected to the electromagnet and controls the current flowing through the electromagnet, thereby controlling the magnetic attraction between the first magnet 210 and the second magnet 220, and thus controlling the force applied to the elastic member 230. This allows the size of the smart ring to be adjusted to suit different users, thereby expanding the applicability and comfort of the smart ring. The provision of the elastic member 230 allows for smoother and more gradual adjustment of the spacing between the first end 111 and the second end 112 of the open-loop ring, facilitating comfortable wearing of the ring during size adjustment.

[0044] Please refer to Figure 2 、 Figure 3 、 Figure 5 and Figure 6 Furthermore, the adjustment mechanism 200 also includes an outer sleeve 240 and an inner sleeve 250 provided at both ends of the open loop of the open loop ring portion, the inner sleeve 250 is inserted into the outer sleeve 240, and a first connection 241 is provided on the side of the outer sleeve 240 away from the inner sleeve 250, the first magnet 210 is fixed to the outer sleeve 240 through the first connection 241, and a second connection 251 is provided on the side of the inner sleeve 250 away from the outer sleeve 240, the second magnet 220 is fixed to the inner sleeve 250 through the second connection 251, and the elastic member 230 is provided between the inner sleeve 250 and the outer sleeve 240.

[0045] Specifically, the adjustment mechanism 200 further includes an outer sleeve 240 and an inner sleeve 250. The outer sleeve 240 is disposed at the first end 111 of the open-loop ring portion, and the inner sleeve 250 is disposed at the second end 112 of the open-loop ring portion. The inner sleeve 250 is inserted into the outer sleeve 240, thereby connecting the inner sleeve 250 and the outer sleeve 240. Thus, the first end 111 and the second end 112 of the open-loop ring portion are connected together through the adjustment mechanism 200. The outer sleeve 240 has a first connection point 241. In the embodiment shown in the drawings of the present invention, the first connection point 241 is a first connecting platform, which is disposed on a side of the outer sleeve 240 near the first end 111 and extends toward the first end 111. In one embodiment, the bottom of the first magnet 210 is fixed to the first connecting platform by bonding. Furthermore, the outer sleeve 240 also has a first connecting hole 243 near the first connecting platform to facilitate interaction between the first magnet 210 and the second magnet 220. Accordingly, the inner sleeve 250 is provided with a second connection 251. In the embodiment shown in the drawings of the present invention, the second connection 251 is a second connection platform, which is provided on the side of the inner sleeve 250 near the second end 112 and extends toward the second end 112. In one embodiment, the bottom of the second magnet 220 is fixed to the second connection platform by bonding. At the same time, the inner sleeve 250 is also provided with a second connection hole 256 near the second connection platform to facilitate the interaction between the second magnet 220 and the first magnet 210. The elastic member 230 is provided between the inner sleeve 250 and the outer sleeve 240. As the magnetic attraction between the first magnet 210 and the second magnet 220 increases, the elastic member 230 is compressed or released, and the inner sleeve 250 moves closer to or further away from the outer sleeve 240, thereby achieving the purpose of adjusting the size of the smart ring.

[0046] Please refer to Figure 3 Furthermore, a sealing groove 253 is provided on the outer wall of the inner sleeve 250 at one end close to the outer sleeve 240 along its circumference, and a sealing ring 254 is provided at the sealing groove 253 .

[0047] Specifically, to improve the sealing performance of the connection between the inner sleeve 250 and the outer sleeve 240, a sealing groove 253 is defined on the outer wall of the inner sleeve 250 at one end near the outer sleeve 240. The sealing groove 253 extends along the entire circumference of the outer wall of the inner sleeve 250, and a sealing ring 254 is embedded in the sealing groove 253. When the inner sleeve 250 is inserted into the outer sleeve 240, the sealing ring 254 abuts against the inner wall of the outer sleeve 240 along its radially outermost wall, thereby ensuring the sealing performance of the connection between the inner sleeve 250 and the outer sleeve 240, as well as the sealing performance of the relative movement between the inner sleeve 250 and the outer sleeve 240.

[0048] Please refer to Figure 3 、 Figure 5 and Figure 6Furthermore, the elastic member 230 is a spring, and a first positioning hole 242 is opened on the side of the outer sleeve 240 away from the inner sleeve 250, and a second positioning hole 252 is opened on the side of the inner sleeve 250 away from the outer sleeve 240. The first tail 231 of the spring is inserted into the first positioning hole 242, and the second tail 232 of the spring is inserted into the second positioning hole 252.

[0049] Specifically, in one embodiment, the elastic member 230 is a spring having a first tail portion 231 and a second tail portion 232 along its length. A first positioning hole 242 is defined on the side of the outer sleeve 240 near the first end 111, and a second positioning hole 252 is defined on the side of the inner sleeve 250 near the second end 112. The first tail portion 231 of the spring is inserted into the first positioning hole 242, and the second tail portion 232 of the spring is inserted into the second positioning hole 252, thereby achieving the positioning and installation of the spring within the inner sleeve 250 and the outer sleeve 240. The specific position, diameter, and cross-sectional shape of the first and second positioning holes 242, 252 are not limited herein. In order to further improve the fixing stability and reliability of the spring, after the first tail 231 and the second tail 232 are respectively inserted into the first positioning hole 242 and the second positioning hole 252, the part of the first tail 231 extending out of the first positioning hole 242 is bent, and the part of the second tail 232 extending out of the second positioning hole 252 is also bent, thereby further improving the stability of the spring during the relative movement of the inner sleeve 250 and the outer sleeve 240.

[0050] Of course, the elastic member 230 can also be a spring, which is installed between the inner sleeve 250 and the outer sleeve 240 by means of snap connection or bonding, and is compressed or released following the relative movement of the inner sleeve 250 and the outer sleeve 240, thereby achieving the adjustment of the size of the smart ring.

[0051] Please refer to Figure 1 and Figure 2 Furthermore, the open-loop ring portion includes an open-loop FPC component 300, the ring body 100 also includes an outer shell 400 covering the outside of the FPC component 300 and an inner shell 500 covering the inside of the FPC component 300, and the adjustment mechanism 200 is arranged between the two ends of the open loop of the FPC component 300.

[0052] Specifically, in one embodiment, the ring body 100 includes an open-loop ring portion, an outer shell 400, and an inner shell 500. The open-loop ring portion includes an open-loop FPC assembly 300. The FPC assembly 300 (Flexible Printed Circuit, or FPC assembly 300) is a highly reliable and highly flexible printed circuit board (PCB) made from a polyimide or polyester film substrate. It is also known as a flexible printed circuit board, soft circuit board, or flexible circuit board. The FPC assembly 300 includes an open-loop assembly body, with an adjustment mechanism 200 disposed between the two ends of the open loop of the FPC assembly 300. That is, in one embodiment, components such as the controller 310 are all disposed on the assembly body. More specifically, the first magnet 210, the second magnet 220, and the controller 310 are secured to the assembly body via a SMT process. In this way, integrating components such as the controller 310 into the FPC assembly 300 facilitates the processing and molding of the smart ring, improving the production efficiency of the smart ring. The outer shell 400 is covered on the outer side of the FPC assembly 300 , and the inner shell 500 is covered on the inner side of the FPC assembly 300 , thereby providing protection and safeguard to both the inner and outer sides of the FPC assembly 300 .

[0053] Of course, the open-loop ring portion may not adopt the structural form of the FPC assembly 300. In one embodiment, the open-loop ring portion may also be arranged in a manner of connecting components such as the controller 310 together through wiring harnesses.

[0054] Furthermore, the inner shell 500 and the outer shell 400 are both closed-loop structures, and both the inner shell 500 and the outer shell 400 are made of soft rubber material.

[0055] Specifically, to enhance the aesthetics of the smart ring, in one embodiment, both the inner shell 500 and the outer shell 400 are closed-loop structures. To ensure the adjustability of the open-loop FPC assembly 300 between the inner and outer shells 500 and 400, both are injection-molded from a soft-rubber material. It is worth noting that in the general plastics industry, plastics with a light specific gravity and relatively low surface hardness, such as PP and PE, are referred to as soft-rubber; while plastics such as PS, ABS, AS, and rigid PVC are referred to as hard-rubber. The specific material of the soft-rubber is not limited here. Furthermore, a non-stick agent is applied between the outer sleeve 240 and inner sleeve 250 and the outer and inner shells 400 and 500. During the molding process of the smart ring, the inner shell 500 and the outer shell 400 are respectively wrapped around the inner and outer sides of the FPC assembly 300. After the soft rubber layers of the inner shell 500 and the outer shell 400 are molded, the outer sleeve 240 and the inner sleeve 250 are peeled off from the outer shell 400 and the inner shell 500, allowing the inner sleeve 250 to move relative to the outer sleeve 240. At this time, the soft rubber around the outer sleeve 240 and the inner sleeve 250 is relatively thin, that is, the outer shell 400 and the inner shell 500 around the outer sleeve 240 and the inner sleeve 250 are thin and elastic, and can be easily squeezed, making it easier to adjust the size of the smart ring.

[0056] In another embodiment, the inner shell 500 and the outer shell 400 are made of soft rubber material only at the corresponding adjustment mechanism 200, and the rest of the inner shell 500 and the outer shell 400 can be made of hard material. In this way, the size adjustment of the smart ring can also be guaranteed. It is worth noting that the hard material can be a hard rubber material or other materials such as metal. When the inner shell 500 and the outer shell 400 are made of soft rubber material at the adjustment mechanism 200 and hard rubber material at the rest, the inner shell 500 and the outer shell 400 can be formed using a double-shot injection molding process.

[0057] Of course, the inner shell 500 and outer shell 400 can also be open-loop structures, with an adjustment mechanism 200 provided at the open loop. The adjustment mechanism 200 is connected between the first end 111 and the second end 112 of the FPC assembly 300, thereby adjusting the size of the smart ring. In this case, the inner shell 500 and outer shell 400 can be made of either soft or hard plastic.

[0058] Please refer to Figure 1 and Figure 2 Furthermore, at least one pressure sensor assembly 320 is installed on the FPC assembly 300. The pressure sensor assembly 320 is electrically connected to the controller 310 and is used to collect the pressure signal of the finger so that the controller 310 can control the current flowing in the electromagnet according to the pressure signal.

[0059] Specifically, at least one pressure sensor assembly 320 is mounted on the FPC assembly 300, meaning that at least one pressure sensor assembly 320 is mounted on the assembly body. Pressure sensor assembly 320 is electrically connected to controller 310 and is used to collect pressure signals from the phone. After pressure sensor assembly 320 transmits the finger pressure signal to controller 310, controller 310 controls the current flowing through the electromagnet based on the pressure signal. This makes the smart ring more comfortable to wear, compared to a setup without pressure sensor assembly 320.

[0060] In one embodiment, to ensure the accuracy of finger pressure signals, multiple pressure sensor assemblies 320 are spaced apart along the circumference of the FPC assembly 300, providing multiple pressure signal collection points around the finger. The controller 310 receives and averages the pressure signals transmitted by the multiple pressure sensor assemblies 320. Subsequently, the controller 310 controls the current flowing through the electromagnet based on the average pressure value. Furthermore, the multiple pressure sensor assemblies 320 are evenly spaced along the circumference of the FPC assembly 300, which improves the accuracy of finger pressure signal collection. Furthermore, an even number of pressure sensor assemblies 320 are evenly spaced along the FPC assembly 300, allowing the pressure sensor assemblies 320 to utilize pressure signals from the relative positions of the finger, further improving the accuracy of the finger pressure signal. In the embodiment shown in the figures of the present invention, four pressure sensor assemblies 320 are provided along the circumference of the FPC assembly 300. Compared to using more than four pressure sensor assemblies 320, this arrangement not only improves the accuracy of finger pressure signal collection but also facilitates the lightweight, compact, and low-cost design of the smart ring.

[0061] More specifically, in the initial state of the smart ring, the ring body 100 is at its largest size, making it relatively easy to put on the finger. After putting it on the finger, the on / off switch is pressed to power the smart ring from the battery. The electromagnet begins to generate magnetic force opposite to that of the other magnetic structure, and the magnetism gradually increases as the current increases. At this point, the first magnet 210 and the second magnet 220 gradually move closer together due to their mutual attraction. In this process, they must overcome the elastic force of the elastic member 230, compressing it and gradually reducing the diameter of the smart ring. Multiple pressure sensor assemblies 320 begin to collect pressure signals from the finger, and the main control chip averages the pressure values ​​collected by the multiple pressure sensor assemblies 320. When the average pressure value reaches a set stop range, the main control chip controls the on / off switch to turn off, severing the connection between the electromagnet and the battery, and thus the interaction between the first magnet 210 and the second magnet 220. This stops the size adjustment of the smart ring, and the smart ring is now at its optimal fit.

[0062] It is worth noting that the pressure setting stop range can be set as needed. Once the pressure value leaves the stop range, the electromagnet will start to increase or decrease the magnetism accordingly, that is, the ring body 100 will begin to shrink or expand, thereby adjusting the smart ring to the appropriate size.

[0063] Of course, the FPC assembly can also be configured without the pressure sensor assembly 320. In this case, an adjustment button can be provided on the ring body 100. When the size of the smart ring needs to be adjusted, the adjustment button is triggered. After the adjustment button is activated, the ring body 100 begins to contract. When the finger feels the appropriate tightness of the ring body 100, or when the ring body 100 is visually sized, the adjustment button is released, causing the smart ring to stop adjusting, thereby adjusting the smart ring to the appropriate size. The adjustment button can be configured as a push button or a touch-sensitive button.

[0064] Please refer to Figure 2 and Figure 4 Furthermore, the inner wall of the FPC assembly 300 is provided with at least one accommodating cavity 330 along its circumference, and the cavity top of the accommodating cavity 330 is provided with an exposure hole 331, which is exposed on the inner wall of the inner shell 500; the pressure sensor assembly 320 includes a pressure sensor 321, a fixing plate 322 and a connecting wire 323 connected in sequence, the pressure sensor 321 is located in the accommodating cavity 330 and is exposed from the exposure hole 331, the fixing plate 322 is connected to the inner wall of the accommodating cavity 330, and the end of the connecting wire 323 away from the fixing plate 322 is electrically connected to the FPC assembly 300.

[0065] Specifically, the inner wall of the FPC assembly 300 is provided with at least one accommodating cavity 330 along its circumference. Accommodating cavity 330 is used to mount and secure the pressure sensor assembly 320. A revealing hole 331 is provided at the top of the cavity 330. When the smart ring is assembled—that is, when the FPC assembly 300 is assembled with the outer shell 400 and inner shell 500—revealing hole 331 can be exposed from the inner wall of the inner shell 500. In other words, the inner shell 500 is provided with at least one through-hole along its circumference, penetrating both its outer and inner walls. This through-hole allows the revealing hole 331 of the accommodating cavity 330 to be exposed.

[0066] like Figure 4As shown, the pressure sensor assembly 320 includes a pressure sensor 321, a fixing plate 322, and a connecting wire 323. The pressure sensor 321 is mounted and fixed on the fixing plate 322. In one embodiment, the pressure sensor 321 is fixed to the fixing plate 322 through the SMT process. Among them, SMT (Surface Mounting Technology, abbreviated as SMT), also known as surface mount technology, is a new generation of electronic assembly technology. It compresses traditional electronic components into devices with a volume of only a few tenths, thereby achieving high density, high reliability, miniaturization, low cost, and automated production of electronic product assembly. The process of assembling components onto a printed (or other substrate) is called the SMT process. A connecting wire 323 is welded to the end face of the fixing plate 322 facing away from the pressure sensor 321, thereby achieving the installation connection between the pressure sensor 321, the fixing plate 322, and the connecting wire 323. The pressure sensor assembly 320 is placed within the accommodating cavity 330, such that the pressure sensor 321 is located within the accommodating cavity 330 and exposed from the exposure hole 331, thereby contacting the surface of the finger to measure the pressure signal of the finger. The fixing plate 322 is connected to the inner wall of the accommodating cavity 330. In one embodiment, the fixing plate 322 is bonded to the inner wall of the accommodating cavity 330 using adhesive. The end of the connecting wire 323 away from the fixing plate 322 is electrically connected to the FPC assembly 300. In one embodiment, the end of the connecting wire 323 away from the fixing plate 322 is connected to the corresponding solder joint on the FPC assembly 300, thereby achieving an electrical connection between the pressure sensor assembly 320 and the FPC assembly 300.

[0067] In one embodiment, to facilitate installation of the pressure sensor assembly 320, mounting holes are provided in the accommodating cavity 330. The accommodating cavity 330 comprises connected side walls and a cavity roof. The side walls are connected end-to-end along the circumference, while the cavity roof is connected to the side walls and located on the side of the accommodating cavity 330 facing the inner shell 500. Thus, the side walls and cavity roof together enclose a storage space that constitutes the accommodating cavity 330 for mounting the pressure sensor assembly 320. The mounting holes provided in the side walls of the accommodating cavity 330 facilitate installation and maintenance of the pressure sensor assembly 320 and contribute to the lightweight design of the smart ring.

[0068] Please refer to Figure 2 Furthermore, the inner wall of the FPC assembly 300 is provided with at least one electrode 360 ​​along its circumference, and the accommodating cavity 330 is formed on the side of the electrode 360 ​​facing the inner wall of the FPC assembly 300. The electrode 360 ​​is exposed on the inner wall of the inner shell 500 and is used to collect the health data of the finger. The FPC assembly 300 is also installed with a Bluetooth chip 340, which is used to receive and transmit the health data of the finger to an external device.

[0069] Specifically, the FPC assembly 300 also includes at least one electrode 360, which is used to collect health data of the finger. The electrode 360 ​​is arranged along the circumference of the inner wall of the FPC assembly 300 and is exposed on the inner wall of the inner shell 500. That is, when the FPC assembly 300, the inner shell 500 and the outer shell 400 are assembled together, the electrode 360 ​​can be exposed from the inner wall of the inner shell 500 to contact the finger, thereby facilitating the collection of health data of the finger. In order to further integrate the smart ring, the accommodating cavity 330 is provided on the side of the inner wall of the FPC assembly 300 facing the electrode 360. In this way, the accommodating cavity 330 is an electrode accommodating cavity, which accommodates the pressure sensor assembly 320. While collecting finger pressure, it can also realize the collection of health data of the finger, thereby expanding the function of the smart ring and improving the scope of application of the smart ring. The FPC assembly 300 also houses a Bluetooth chip 340, which is electrically connected to the controller 310 and is used to receive and transmit finger health data to external devices for easy monitoring and tracking of the user's health. The electrodes 360 and Bluetooth chip 340 are secured to the FPC assembly 300 using a SMT process.

[0070] Please refer to Figure 2 Furthermore, the FPC assembly 300 is also equipped with a motor 350, which is electrically connected to the controller 310 and controlled by the controller 310 to generate vibrations on the fingers. Specifically, the FPC assembly 300 is also equipped with a motor 350, which is electrically connected to the controller 310. When the user's health data is abnormal, the controller 310 controls the motor 350 to vibrate, so that the fingers feel the vibration signal, so as to remind the user to pay attention to the abnormality of the health data and pay attention to their own health status in time. Of course, the motor 350 can also be used for other functions, such as monitoring or reminding the user to exercise, etc., which are not limited here. Among them, the motor 350 is fixed to the FPC assembly 300 through the SMT process.

[0071] In one embodiment, a smart ring includes an outer shell 400, an FPC assembly 300, an inner shell 500, and an adjustment mechanism 200. The adjustment mechanism 200 includes a first magnet 210, a second magnet 220, a spring, an inner sleeve 250, and an outer sleeve 240. During the smart ring molding process, the FPC assembly 300 is first molded. The pressure sensor assembly 320 is first installed in the accommodating cavity 330 of the FPC assembly 300. The first magnet 210 is then connected to the outer sleeve 240, the second magnet 220 is then connected to the inner sleeve 250, and the spring is then installed between the inner sleeve 250 and the outer sleeve 240. The gaps between the first magnet 210, the second magnet 220, and the spring and the inner sleeve 250 and the outer sleeve 240 are simultaneously sealed. This completes the molding of the FPC assembly 300.

[0072] Next, the FPC assembly 300 and housing 400 are molded. A female mold is placed outside the FPC assembly 300, and a male mold is placed inside the FPC assembly 300. A soft adhesive layer is then injected between the FPC assembly 300 and the female mold and cured to form the mold. Magnets are placed within the male mold to attract the first magnet 210, second magnet 220, and electrode 360 ​​in the FPC assembly 300, preventing the impact force during the molding of the housing 400 from dislodging the FPC assembly 300. This completes the molding of the FPC assembly 300 and housing 400.

[0073] Finally, the FPC assembly 300 with the outer shell 400 and the inner shell 500 are molded. A female mold is set on the outside of the FPC assembly 300 with the outer shell 400, and another male mold is set on the inside of the FPC assembly 300 with the outer shell 400. Then, a soft rubber layer is injected between the FPC assembly 300 with the outer shell 400 and the other male mold and cured to form. Among them, a magnet is still set in the other male mold to adsorb the first magnet 210, the second magnet 220 and the electrode 360 ​​in the FPC assembly 300 with the outer shell 400, so as to prevent the impact force during the molding process of the outer shell 400 from washing away the FPC assembly 300 with the outer shell 400. In this way, the molding of the FPC assembly 300 with the outer shell 400 and the inner shell 500 is realized, that is, the molding of the smart ring is realized.
