[0055] Referring to Figures 1 to 5 , the present application provides a smart ring 100, comprising an annular housing 10 and at least one electronic component 20. The annular housing 10 comprises an outer ring 11, an inner ring 12, and a receiving cavity 13 between the outer ring 11 and the inner ring 12. At least one electronic component 20 is disposed in the receiving cavity 13. The smart ring 100 further comprises a first electrode 30 and a second electrode 40, which are spaced apart on the circumference C (as shown in Figure 1) of the inner surface of the annular housing 10, and the first electrode 30 and the second electrode 40 are electrically connected to the at least one electronic component 20.

[0056] The smart ring 100 provided in this application has a housing cavity formed between the outer ring 11 and the inner ring 12 of the annular housing 10. At least one electronic component 20 is disposed within the housing cavity. A first electrode 30 and a second electrode 40 electrically connected to the at least one electronic component 20 are disposed along the circumference of the inner surface of the annular housing 10 for contact with human skin. Thus, when the user wears the smart ring 100 on their finger, the first electrode 30 and the second electrode 40 can contact the finger skin to collect physiological signals from the human body and transmit them to the electronic component 20, thereby realizing the health monitoring function of the smart ring 100.

[0057] The first electrode 30 and the second electrode 40 can be used to collect one or more physiological detection signals, including at least one of skin electrode activity (EDA) signal, body impedance signal, heart rate detection signal, blood pressure signal, electrocardiogram signal and body temperature signal.

[0058] In some embodiments, at least one of the first electrode 30 and the second electrode 40 can be reused to obtain multiple physiological detection signals to reduce the number of electrodes on the smart ring 100, which is more conducive to streamlining the structure of the smart ring 100 and reducing costs. For example, at least one of the first electrode 30 and the second electrode 40 can be reused to obtain EDA signals and body temperature signals. For another example, the first electrode 30 and the second electrode 40 can be reused to obtain EDA signals and electrocardiogram signals. In other embodiments, the first electrode 30 and the second electrode 30 can be reused as charging terminals while the first electrode 30 and the second electrode 40 are used to obtain physiological detection signals. For example, while the first electrode 30 and / or the second electrode 40 are used as body temperature sensing electrodes, the first electrode 30 and the second electrode 40 are used as charging terminals. The specific implementation of electrode reuse is not limited here.

[0059] The annular housing 10 includes an outer ring 11 and an inner ring 12 , wherein the outer wall of the outer ring 11 may serve as at least a portion of the outer surface of the annular housing 10 , and the inner wall of the inner ring 12 may serve as at least a portion of the inner surface of the annular housing 10 .

[0060] The outer ring 11 can be made of a conductive material such as metal. In some embodiments, the outer ring 11 can be a titanium alloy ring, a stainless steel ring, or an aluminum alloy ring. As an example, the outer ring 11 is a titanium alloy ring, which makes the overall hardness of the smart ring 100 higher and more aesthetically pleasing.

[0061] The inner ring 12 may be made of a conductive material such as metal or an insulating material such as non-metal, or a portion of the inner ring 12 may be made of a conductive material such as metal and a portion of the inner ring 12 may be made of an insulating material such as non-metal.

[0062] In some embodiments, the inner ring 12 can be made of a non-metallic material. For example, the inner ring 12 can be made of a moldable material such as epoxy resin. In this case, at least one hole can be provided in the inner ring 12, and the first electrode 30 and the second electrode 40 can protrude from the inner surface of the inner ring 12 through the at least one hole. Alternatively, the first electrode 30 and the second electrode 40 can be provided as a metal coating on the inner surface of the inner ring 12.

[0063] In other embodiments, the inner ring 12 may be made of a metal material, wherein the metal material of the inner ring 12 and the metal material of the outer ring 11 may be the same or different. In this case, at least a portion of the inner wall of the inner ring 12 may serve as the first electrode 30 and the second electrode 40, i.e., a first portion of the inner surface of the inner ring 12 serves as the first electrode 30, and a second portion of the inner surface of the inner ring 12 serves as the second electrode 40. Alternatively, at least one hole may be defined in the inner wall of the inner ring 12, through which the first electrode 30 and the second electrode 40 may protrude from the inner wall of the inner ring 12. An insulating layer may be provided between the first electrode 30 and the second electrode 40 and the inner wall of the inner ring 12.

[0064] An accommodating cavity 13 may be provided between the outer ring 11 and the inner ring 12. In some embodiments, the cavity wall of the accommodating cavity 13 may include the outer ring 11 and the inner ring 12. Alternatively, other components, such as other annular components, may be provided between the outer ring 11 and the inner ring 12. Accordingly, the cavity wall of the accommodating cavity 13 may include at least one of the outer ring 11 and the inner ring 12. As an example, the outer ring 11 and the inner ring 12 are both made of metal materials. In this case, an isolation ring 60 made of an insulating material such as a non-metallic material may be provided between the outer ring 11 and the inner ring 12. The non-metallic material may be epoxy resin, polyurethane, polyethylene, etc., and the isolation ring 60 may be formed by glue pouring or other processes. In this case, the accommodating cavity 13 may be formed between the outer ring 11 and the isolation ring 60, or between the inner ring 12 and the isolation ring 60. As an example, the accommodating cavity 13 can be formed between the outer ring 11 and the isolating ring 60. Accordingly, the cavity wall of the accommodating cavity 13 can include at least a portion of the outer ring 11 and at least a portion of the isolating ring 60. The isolating ring 60 can be disposed on the outer surface of the inner ring 12. Here, assuming that the surface of the inner ring 12 serving as the inner surface of the annular housing 10 is the first surface, the second surface of the inner ring 12, opposite the first surface, is the outer surface of the inner ring 12. For example, the isolating ring 60 can be formed by a coating or a glue layer disposed on the outer surface of the inner ring 12. As another example, the accommodating cavity 13 can be formed between the inner ring 12 and the isolating ring 60. Accordingly, the cavity wall of the accommodating cavity 13 can include at least a portion of the inner ring 12 and at least a portion of the isolating ring 60. The isolating ring 60 can be disposed on the inner surface of the outer ring 11. For example, the isolating ring 60 can be formed by a coating or a glue layer disposed on the inner surface of the outer ring 11.

[0065] At least one electronic component 20 is provided in the accommodating cavity 13, and the at least one electronic component 20 can be provided on the circuit board 70. The at least one electronic component 20 may include at least one of a charging component and a physiological parameter sensor. The physiological parameter sensor may be a sensor that obtains physiological parameters through electrode signals. As an example, the physiological parameter sensor may include at least one of a bioelectrical impedance sensor (BIA), a body temperature sensor, an electrocardiogram sensor, and an EDA sensor. In addition, the accommodating cavity 13 may also be provided with at least one of a processor, a memory, a battery assembly, a communication assembly (wired and / or wireless communication module), a positioning assembly, etc., which are not limited here.

[0066] In some embodiments, an optical detection module 24 can be provided in the accommodating cavity 13. The optical detection module 24 can be used to detect the pulse wave signal of the human body to obtain one or more physiological parameters of the human body, such as heart rate, blood oxygen saturation, blood pressure, blood sugar, etc., or it can further determine whether there are abnormalities in the one or more physiological parameters, and promptly remind the user when abnormal data is detected.

[0067] The optical detection module 24 may include a plurality of optical devices, such as at least one light emitter and at least one light detector, wherein the light emitter may include a monochromatic (e.g., green, red, or infrared) LED, a bicolor (e.g., red and infrared, etc.) LED, or a tricolor (e.g., green, red, and infrared, etc.) LED for emitting a light signal of at least one wavelength, and the light detector may include a photodiode (PD), etc., which may be used to detect light signals within a certain wavelength range, such as light signals with a wavelength within the range of 400nm to 1000nm. The optical detection module 24 may be a reflective or transmissive optical sensor. The spacing between the light emitter and the light detector may be 3mm to 12mm, which is not limited here. Specifically, the light emitter may be used to emit light signals of one or more wavelengths, and the emitted light signals may be incident on human skin and received by the light detector after being reflected and / or refracted by the human skin. By analyzing and processing the light signals received by the light detector, the measurement results of the physiological parameters of the human body may be obtained. For example, the optical detection module 24 can use green light to detect heart rate. For another example, the optical detection module 24 can use red light and infrared light to detect blood oxygen saturation. The light emitter and the light detector can be located on the same side of the human skin. For example, the light emitter and the light detector can be arranged adjacent to each other in the annular housing 10. Alternatively, the light emitter and the light detector can be located on different sides of the human skin. For example, the light emitter and the light detector can be located in opposite areas of the annular housing 10 of the smart ring 100. The specific implementation of the optical detection module 24 is not limited here.

[0068] In some embodiments, in order to allow the light signal to be incident on the human skin after being emitted from the light emitter, and to allow the light signal returned from the human skin to be received by the light detector, light-transmitting areas can be respectively set at positions corresponding to the light emitter and the light detector on the inner ring 12, and a light-shielding area can be set between the light-transmitting areas. As an example, the inner ring 12 can be made of a light-transmitting material, such as glass, sapphire, epoxy resin, transparent plastic, etc., and a light-shielding layer can be set at a position not corresponding to the light emitter and the light detector to block the passage of light, prevent crosstalk and improve the aesthetics. For example, an ink layer can be set on the surface of the inner ring, wherein the ink layer contains ink in an area not corresponding to the optical device or between areas corresponding to the optical device. As another example, a bracket can also be set between the inner ring 12 and the optical detection module, and corresponding light-transmitting areas and light-shielding areas can be set on the bracket, wherein the bracket can be set on the outer surface of the inner ring 12, but the embodiments of the present application are not limited to this. As another example, the inner ring 12 may be made of an opaque material, and holes may be provided at positions corresponding to the light emitters and light detectors, with light-transmitting lenses provided in the holes to form light-transmitting areas.

[0069] In some embodiments, the optical detection module 24 may further include at least one convex lens 241 arranged corresponding to the multiple optical devices. The convex lens 241 may be elliptical or in other shapes to focus the light signal, thereby helping to reduce the power consumption of the optical detection module 24. In addition, the convex lens 241 may serve as part of the inner surface of the smart ring 100, increasing the contact with the finger skin and helping to improve measurement accuracy. In addition, the convex lens 241 may also serve as a position guide for the smart ring 100 when it is worn or charged. For example, when the smart ring 100 is placed in the charging box 200 for charging, the convex lens 241 may also be adapted to be positioned with the guide groove on the charging box 200, which can achieve a foolproof positioning effect and improve charging safety. In the example shown in FIG2 , the convex lens is an elliptical runway lens, which may be formed of a light-transmitting material, such as a transparent silicone material, an epoxy resin material, and the like.

[0070] As an example, at least one convex lens 241 can be provided on the inner surface of the annular housing 10 at a position corresponding to the optical device. Specifically, at least one opening 123 can be provided on the inner ring 12, and a convex lens 241 protruding from the inner surface of the inner ring 12 can be embedded in the opening 123. For example, at least one convex lens 241 can be provided in the accommodating cavity 13, and an opening 123 can be provided at a corresponding position on the inner ring 12, so that the convex lens 241 protrudes from the opening 123. As another example, the inner ring 12 can be made of a light-transmitting material and have at least one convex hull at a position corresponding to the optical device. The at least one convex hull can serve as the convex lens 241. In other words, the inner surface of the inner ring 12 can include at least one convex hull, and the at least one convex hull can be used to converge the optical signal.

[0071] In some embodiments, in order to prevent the optical signal emitted by the optical transmitter from directly entering the optical detector and causing crosstalk, the optical detection module 24 may further include an optical barrier, which may be disposed between the optical transmitter and the optical detector. For example, one end of the optical barrier is connected to the circuit board, and the other end is connected to the surface of the inner ring 12. The specific implementation of the optical barrier is not limited here.

[0072] In some optional embodiments, as shown in Figures 2 and 3, the first electrode 30 and the second electrode 40 are both semi-annular or approximately semi-annular in shape. The first electrode 30 and the second electrode 40 can form a ring or a nearly ring-shaped shape along the circumference of the inner surface of the inner ring 12. In this way, the first electrode 30 and the second electrode 40 can have a larger surface area, and accordingly, a larger contact area with the finger skin, which is beneficial for improving the efficiency and accuracy of physiological parameter detection. As an example, the first electrode 30 and the second electrode 40 occupy more than two-thirds of the circumference of the inner ring 12. As another example, the first electrode 30 and / or the second electrode 40 occupy more than two-thirds of the width direction W of the inner ring 12 (as shown in Figure 2). As another example, the first electrode 30 and / or the second electrode 40 occupy more than two-thirds of the area on the inner surface of the inner ring 12. In this way, the first electrode 30 or the second electrode 40 has a larger contact area with the user's finger skin.

[0073] In some embodiments, as shown in FIG2 , the inner ring 12 includes a first electrode 30 and a second electrode 40 arranged along the circumferential direction, and an isolating member 50 located between the first electrode 30 and the second electrode 40. The isolating member 50 is made of an insulating material such as a non-metal. In this way, the area in which the first electrode 30 and the second electrode 40 are in contact with the skin is large enough, which is beneficial for the smart ring 100 to accurately and efficiently collect signals through the first electrode 30 and the second electrode 40. At the same time, the isolating member 50 insulates the first electrode 30 and the second electrode 40, and also plays the role of antenna clearance. In the example shown in FIG2 , two isolating members 50 are provided in the gap between the first electrode 30 and the second electrode 40, respectively located at the connection portion of the first electrode 30 and the second electrode 40, but in other embodiments, the number of isolating members 50 may be more or less, and is not limited here.

[0074] In some examples, the first electrode 30 and the second electrode 40 may be the same electrode, which can ensure the signal collection effect and facilitate production and processing.

[0075] In addition, in some embodiments, at least one of the first electrode 30 and the second electrode 40 is provided with at least one opening 123, and the at least one opening 123 can correspond to a plurality of optical devices included in the optical detection module 24 provided in the accommodating cavity 13, so that a plurality of convex lenses 241 corresponding to the plurality of optical devices extend from the opening 123.

[0076] In the examples shown in Figures 2 and 5 , three optical devices are disposed within the accommodating cavity 13 and arranged along the circumference of the annular housing 10: a first optical device 242, a second optical device 243, and a third optical device 244. The second optical device 243 is located in the region where the isolator 50 connects to the first electrode 30 and the second electrode 40. The first and third optical devices 242 and 244 are disposed on either side of the second optical device 243. As an example, the first and third optical devices 242 and 244 are symmetrically disposed about the second optical device 243. Each of the first, second, and third optical devices 242, 243, and 244 can be a light emitter or a light detector. In some examples, the second optical device 243 can be a light emitter, and the first and third optical devices 242 and 244 can be light detectors. In other examples, the second optical device 243 can be a light detector, and the first and third optical devices 242 and 244 can be light emitters. In other examples, the number of optical devices can be greater or lesser, or they can be arranged in other ways, which are not limited here. Here, the second optical device 243 is used as a light emitter, and the first optical device 242 and the third optical device 244 are used as light detectors. The second optical device 243 can form a first optical detection channel with the first optical device 242, and the second optical device 243 can form a second optical detection channel with the third optical device 244. In some examples, when the second optical device 243 is a dual-color LED or a tri-color LED, the second optical device 243 can include two or more light-emitting devices. In this case, each of the two or more light-emitting devices can form a different optical detection channel with the first optical device 242 and / or the third optical device 244, which is not limited here.

[0077] In the example shown in FIG3 , the optical detection module 24 includes four optical components: a first light emitter 2431, a second light emitter 2432, a first light detector 242, and a second light detector 244. The first light emitter 2431 and the second light emitter 2432 are located near the region where the spacer 50 connects to the first electrode 30 and the second electrode 40. The first light detector 242 and the second light detector 244 are located on either side of the first light emitter 2431 and the second light emitter 2432. The first light emitter 2431 and the second light emitter 2432 can be configured to emit visible light or infrared light and, together with the first light detector 242 and the second light detector 244, form at least one optical detection channel for collecting physiological signals. As an example, the spacing between the first light emitter 2431 and the first light detector 242 is 4 mm, forming the first optical detection channel. The spacing between the first light emitter 2431 and the second light detector 244 is 12 mm, forming the second optical detection channel. The distance between the second light emitter 2432 and the first light detector 242 is 8 mm, and the two constitute the third optical detection channel. The distance between the second light emitter 2432 and the second light detector 244 is 8 mm, and the two constitute the fourth optical detection channel. Multiple optical devices form a total of four optical detection channels, which makes the measurement signal quality higher and the obtained physiological parameters more accurate. Similarly, in some examples, when the first light emitter 2431 or the second light emitter 2432 is a two-color LED or a three-color LED, more optical detection channels can be formed, or each optical detection channel can include more components, which is not limited here.

[0078] In addition, a convex lens 241 is correspondingly provided for each optical device. In the example shown in FIG2 , the first electrode 30 and the second electrode 40 both include a complete opening 123 located in the middle region and a half opening 123 located at the end. The half openings 123 of the first electrode 30 and the second electrode 40 can form a complete opening 123 after the smart ring 100 is assembled. At this time, the two convex lenses 241 corresponding to the first optical device 242 and the third optical device 244 can respectively extend through the complete openings 123 provided on the first electrode 30 and the second electrode 40, and the convex lens 241 corresponding to the second optical device 243 can extend through the opening 123 formed by the combination of the first electrode 30 and the second electrode 40.

[0079] In addition, in the example shown in FIG2 , an isolation ring 60 is provided between the outer ring 11 and the inner ring 12, and a housing cavity 13 is formed between the isolation ring 60 and the outer ring 11. The isolation ring 60 can be made of a non-metallic material, such as a silicone material or a resin material, and at least one of the convex lens 241 and the isolating member 50 can be provided on the isolation ring 60. The outer ring 11 and the inner ring 12 are respectively fixed on different sides (i.e., the inside and the outside) of the isolation ring 60. With such a configuration, the isolation ring 60 can not only provide insulation but also improve the overall aesthetics of the smart ring 100. The housing cavity 13 provides a housing space for the electronic components 20, so that the space of the smart ring 100 can be reasonably utilized and various functions can be realized.

[0080] In other embodiments, as shown in FIG5 , the inner surface of the inner ring 12 is symmetrically provided with a first hole 121 and a second hole 122 along the circumferential direction. The first electrode 30 is provided on the inner surface of the inner ring 12 through the first hole 121, and the second electrode 40 is provided on the inner surface of the inner ring 12 through the second hole 122. In this case, the inner wall of the inner ring 12 can be made of a non-metallic material, or an insulating layer can be provided between the inner wall of the inner ring 12 and the first electrode 30 and the second electrode 40. The first electrode 30 and the second electrode 40 are provided on both sides of the optical detection module, that is, they are provided around the optical devices 242, 243, and 244 in the circumferential direction. In this case, a plurality of convex lenses 214 can be provided on the inner wall of the inner ring 12. For example, the inner surface of the inner ring 12 includes a plurality of convex hulls serving as the convex lenses 214, but this is not limited in this embodiment of the present application.

[0081] In some examples, the smart ring 100 further includes a circuit board 70 disposed within the accommodating cavity 13. The circuit board 70 may be provided with one or more electronic components 20, or further provided with one or more other components, such as at least one of an optical detection module 24, a temperature sensor module 23, a charging module 22, a skin electrical activity sensor module 21, and a communication module. Accordingly, one end of the first electrode 30 and the second electrode 40 may be provided on the circuit board 70, and the other end may protrude from the inner surface of the inner ring 12. In this case, the first electrode 30 and the second electrode 40 may have a certain thickness. For example, as shown in FIG5 , the first electrode 30 and the second electrode 40 may include a support portion 31 and a detection portion 32, wherein the support portion 31 is provided on the circuit board 70, and the detection portion 32 protrudes from the inner surface of the inner ring 12. The support portion 31 may be fixed to the circuit board 70, for example, by adhesive, positioning posts, screws, etc. Alternatively, the support portion 31 may be fixed to the outer ring 11. For example, as shown in FIG5 , the support portion 31 is provided with a fixing groove 311. A positioning member 1131 provided on the outer ring 11 is embedded in the fixing groove 311, thereby positioning the first electrode 30 and the second electrode 40. To further stabilize the position of the first electrode 30 and the second electrode 40, in some examples, adhesive or other fixing members may be provided at the contact position between the positioning member 1131 and the detection portion 32, which is not limited here.

[0082] As shown in Figures 3 and 5 , to accommodate the annular structure of the smart ring 100 and maximize the number of electronic components 20 placed on the circuit board 70, the circuit board 70 can be configured in an arc shape. The circuit board 70 can include a rigid circuit board 71 and a flexible circuit board 72. For example, the circuit board 70 includes at least two rigid circuit boards 71 ​​and a flexible circuit board 72 for connecting the at least two rigid circuit boards 71. The rigid circuit board 71 can be, for example, a printed circuit board (PCB), on which the electronic components 20 to be placed can be placed to ensure the stability of the electronic components 20. The flexible circuit board 72 can be, for example, a flexible printed circuit (FPC), which connects two adjacent rigid circuit boards 71 ​​to form the required curvature to fit the annular shape of the smart ring 100. In some embodiments, the curvature of the flexible circuit board 72 can be used to adjust the storage space of the smart ring 100, allowing the same circuit board 70 to be used in smart rings 100 of different sizes, thereby achieving universal circuit board 70 compatibility. The circuit board 70 can be a rigid-flexible board. By adjusting the curvature of the flexible circuit board 72 and the angle between the adjacent rigid circuit boards 71 ​​according to the size of the smart ring 100, the curvature and effective length of the rigid-flexible board can be modified according to the size and shape of the smart ring 100 without adding any additional mechanisms or components. In some examples, to enhance the structural strength of the flexible circuit board 72, a reinforcing plate, such as a steel sheet, can be provided in the area where the flexible circuit board 72 is located. This is not limited here.

[0083] In some embodiments, at least one electronic component 20 in the smart ring 100 can be entirely disposed on the rigid circuit board 71, while the flexible circuit board 72 may not be provided with any electronic components 20, but may only be provided with necessary connection terminals or connectors. In other embodiments, at least one electronic component 20 in the smart ring 100 can be partially disposed on the rigid circuit board 71 and partially disposed on the flexible circuit board 72. In other embodiments, other electronic components in the smart ring 100 can be disposed on either the rigid circuit board 71 or the flexible circuit board 72. For example, at least one electronic component 20 can be disposed on the rigid circuit board 71, while other electronic components can be disposed on the flexible circuit board 72. This is not limited here.

[0084] The first electrode 30 and the second electrode 40 can be electrically connected to the rigid circuit board 71 and / or the flexible circuit board 72 of the circuit board 70. In some embodiments, the circuit board 70 can be electrically connected to the first electrode 30 and the second electrode 40 via a wire 73 or other type of electrical connector, wherein the first electrode 30 and the second electrode 40 can be electrically connected to the rigid circuit board 71 or the flexible circuit board 72. In some embodiments, solder pads can be reserved on the rigid circuit board 71 or the flexible circuit board 72, and the first electrode 30 and the second electrode 40 can be soldered to the solder pads using surface mount technology (SMT). One end of the wire 73 can be soldered to the first electrode 30 and the second electrode 40, and the other end can be connected to the rigid circuit board 71 or the flexible circuit board 72. In some embodiments, a metal sheet can be provided in the accommodating cavity 13 of the annular housing 10, and the connection between the outer ring 11, the inner ring 12, or the circuit board 70 and the first electrode 30 and the second electrode 40 can be achieved by welding the metal sheet. Alternatively, the circuit board 70 may be bonded to the first electrode 30 and the second electrode 40 respectively using a conductive adhesive to achieve electrical connection between the circuit board 70 and the first electrode 30 and the second electrode 40 .

[0085] The optical detection module 24 can be disposed on a rigid circuit board 71 or a flexible circuit board 72. In some embodiments, the area on the circuit board 70 used to dispose the optical components can be provided with an opaque material, such as being made of an opaque material or provided with a light-shielding layer, to prevent crosstalk between different optical components. For example, the area on the circuit board 70 between the light emitter and the light detector can be provided with an opaque material. In other embodiments, the first optical component 242 and the third optical component 244 can be encapsulated on the rigid circuit board 71 using a transparent material, such as a silicone material or a resin material, while an opaque optical barrier can be provided around the second optical component 243. Alternatively, opaque optical barriers can be provided around the first optical component 242 and the third optical component 244, respectively, without limitation herein.

[0086] The circuit board 70 can be fixed to the housing cavity 13 of the smart ring 100 by a variety of positioning methods, such as by gluing, positioning members, welding, etc. In some embodiments, the rigid circuit board 71 and the flexible circuit board 72 can be positioned in the annular housing 10 using different positioning methods. Referring to the example shown in Figure 4, at least one of a first positioning portion 112 and a second positioning portion 113 is provided on the inner wall 111 of the outer ring, wherein at least a portion of the rigid circuit board 71 is fixed to the first positioning portion 112 by a first positioning method, and at least a portion of the flexible circuit board 72 is fixed to the second positioning portion 113 by a second positioning method, wherein the first positioning method is different from the second positioning method. In some examples, the first positioning method can be gluing or welding, and the second positioning method can be positioning based on positioning members. For example, the second positioning portion 113 is provided with at least one positioning member 1131, and the flexible printed circuit board 72 is provided with a positioning adapter 721 that is adapted to connect with the at least one positioning member 1131. The positioning member 1131 may be a positioning post, and the positioning adapter 721 may be a positioning hole. Alternatively, the positioning member 1131 may be a screw, and the positioning adapter 721 may be a nut, etc. In this way, by respectively securing the rigid printed circuit board 71 and the flexible printed circuit board 72 in the accommodating cavity 13 through different positioning methods, the positioning effect of the printed circuit board 70 can be improved.

[0087] By adapting and connecting the positioning adapter 721 on the flexible circuit board 72 with the positioning piece 1131, the flexible circuit board 72 can be fixed on the outer ring 11, making it easier to fix the circuit board 70 on the outer ring 11, preventing the circuit board 70 from moving relative to the outer ring 11, ensuring the functional stability of the smart ring 100, and at the same time improving the assembly convenience of the smart ring 100.

[0088] In some embodiments, in order to further improve the positioning effect, as shown in Figures 4 and 5, a groove 1132 can be provided on the second positioning portion 113, and one end of the positioning member 1131 is fixedly disposed in the groove 1132, and the other end of the positioning member 1131 is connected to the first electrode 30 or the second electrode 40 through the positioning adapter 721. In this way, the positioning member 1131 can not only play the role of positioning the circuit board 70, but also further realize the role of positioning the electrode. Among them, the positioning member 1131 can be fixed in the groove 1132 by means of dispensing glue or snap-fitting, and connected to the first electrode 30 or the second electrode 40 by means of dispensing glue, welding, snap-fitting, etc. Correspondingly, a fixing groove 311 can be provided on the first electrode 30 and / or the second electrode 40, and the end of the positioning member 1131 can be disposed in the fixing groove 311 and fixed by means of dispensing glue, snap-fitting, etc.

[0089] Referring to the example shown in Figure 5, the outer ring 11 of the smart ring 100 includes a positioning piece 1131, and the circuit board 70 is provided with a positioning hole adapted to the positioning piece 1131. One end of the positioning piece 1131 is fixed to the outer ring 11, and the other end of the positioning piece 1131 is connected to the fixing groove 311 on the first electrode 30 or the second electrode 40 through the positioning hole on the circuit board 70. The adaptive positioning structure of the positioning piece and the positioning hole can simultaneously achieve fixation of the circuit board 70 and the electrode.

[0090] In some embodiments, as shown in Figures 3 and 5 , the smart ring 100 further includes a curved battery assembly 80. The curved battery assembly 80 is semi-annular or quasi-semi-annular in shape. The curved battery assembly 80 and the circuit board 70 are disposed in different areas within the accommodating cavity 13 along the circumference of the accommodating cavity 13. For example, the curved battery assembly 80 and the circuit board 70 may form a shape that fits within the annular housing 10, such as a ring or quasi-annular shape. In some examples, at least one first gap may exist between the curved battery assembly 80 and the circuit board 70. For example, the curved battery assembly 80 and the circuit board 70 may not overlap at all. In this case, in the examples shown in Figures 2 and 3 , the curved battery assembly 80 and the circuit board 70 may be offset from the first electrode 30 and the second electrode 40, such that the first gap between the curved battery assembly 80 and the circuit board 70 and the second gap between the first electrode 30 and the second electrode 40 do not overlap along the circumference of the annular housing 10. This allows for more efficient utilization of the annular accommodation space of the accommodating cavity 13, improves the compactness of the internal structure of the smart ring 100, and reduces the thickness of the smart ring 100. In some examples, at least one first gap between the curved battery assembly 80 and the circuit board 70 and at least one second gap between the first electrode 30 and the second electrode 40 are evenly distributed along the circumference of the annular housing 10. For example, as shown in FIG2 , the curved battery assembly 80 and the circuit board 70 are arranged with a vertical spacing, i.e., disposed at the upper and lower portions of the annular housing 10, respectively, while the first electrode 30 and the second electrode 40 are arranged with a horizontal spacing, i.e., disposed at the left and right portions of the annular housing 10, respectively, such that a line connecting the two first gaps and a line connecting the two second gaps are perpendicular or nearly perpendicular to each other, but this is not limited in this embodiment of the present application.

[0091] In some embodiments, the various components of the same module can be arranged on the same circuit board, or different components of the same module can be arranged on different circuit boards. For example, the first electrode 30 and the second electrode 40 can be arranged on different circuit boards. For another example, the light emitter and the light detector of the optical detection module 24 can be arranged on different circuit boards, or different light emitters and / or different light detectors of the optical detection module 24 can be arranged on different circuit boards. As an example, the various light emitters of the optical detection module 24 can be arranged on the same circuit board, and different light detectors can be arranged on different circuit boards, and the different circuit boards are different from the circuit boards where the light emitters are located. As another example, each individual optical device of the optical detection module 24 can be arranged on a separate circuit board. For example, each two-color or three-color LED can be arranged on a separate circuit board, and each PD can be arranged on a separate circuit board, which is not limited here.

[0092] In some embodiments, at least one electronic component 20 may include an electrode-based charging module or one or more physiological parameter sensors. Referring to the example shown in FIG6 , at least one electronic component 20 may include at least one of a skin electrode activity sensor module 21 and a body composition sensor module, each of which is electrically connected to a first electrode 30 and a second electrode 40. Furthermore, the accommodating cavity 13 may also include at least one of a charging module 22 and a temperature sensor module 23. Optionally, at least one of the charging module 22 and the temperature sensor module 23 may reuse the first electrode 30 and the second electrode 40 with at least one of the skin electrode activity sensor module 21 and the body composition sensor module. Thus, when the smart ring 100 is worn on a finger, the first electrode 30 and the second electrode 40 contact the finger skin, collecting signals and transmitting them to the sensor module disposed on the circuit board 70. The sensor module may process the signals to obtain physiological measurement data. In some embodiments, the smart ring 100 may further include a processor module such as a controller and a switching circuit, wherein the switching circuit may be used to switch the connection circuit between the first electrode 30 and the second electrode 40 and each component, so that the first electrode 30 and the second electrode 40 can measure different types of physiological data, or switch between charging and physiological data measurement. The controller can be used to send a control signal to the switching circuit. In other embodiments, the smart ring 100 may not include a controller, but may include a wireless communication module, such as a Bluetooth communication module, a WIFI communication module, and the like. The wireless communication module can receive a control signal sent by a mobile terminal or a server, and the switching circuit can switch the connection circuit between the first electrode 30 and the second electrode 40 and each component under the control of the control signal. In addition, after obtaining the physiological detection signal and / or processed data, the smart ring 100 can send the physiological detection signal and / or processed data to a mobile terminal or server through a wireless communication module, so that the mobile terminal or server can further process the physiological detection signal and / or processed data to obtain physiological detection results, and / or output the received processed data and / or physiological detection results to the user. The mobile terminal may include other wearable devices such as mobile phones and smart bracelets, computer devices such as tablet computers, and electronic devices such as vehicle-mounted terminals. The mobile terminal can output the physiological detection results through audio, touch, display, etc. Accordingly, the user can view their own health data on the mobile terminal, such as emotional state information, physiological stress information, electrocardiogram information, body composition information, body temperature, heart rate, blood oxygen saturation, etc., or, based on the above physiological detection signals and / or processed data, health improvement suggestions can also be obtained and output to the user. Optionally, the user can interact with the mobile terminal to instruct the smart ring 100 to perform specific operations or functions.

[0093] In some embodiments, the skin electrode activity sensing module 21 can detect skin electrode activity signals indicating physiological and emotional changes of the user through the first electrode 30 and the second electrode 40. The skin electrode activity sensing module 21 can transmit the skin electrode activity signals directly to the mobile terminal or server, or can transmit the skin electrode activity signals to the mobile terminal or server after performing one or more processing. For example, the processor module of the smart ring can obtain feature data related to emotional response based on the skin electrode activity signals, and send the feature data to the mobile terminal or server so that the mobile terminal or server can process the received feature data to obtain emotion monitoring results. Alternatively, the processor module of the smart ring can obtain an emotion monitoring result based on the skin electrode activity signals to determine whether the user has an emotional response, and send it to the mobile terminal or server so that the mobile terminal or server can output the emotion monitoring result to the user or perform subsequent analysis and statistics. In other embodiments, the smart ring may further include an output module, such as at least one of an audio output module, a tactile output module, and a display. Accordingly, after the processor module obtains the emotion monitoring result, the output module can output the emotion monitoring result to the user.

[0094] The emotion monitoring results can be used to indicate whether the user has an emotional reaction, such as excitement, calmness, anger, or sadness, etc. In some embodiments, the detected emotional reactions can be accumulated to determine the user's emotional tendency or summary over a longer period of time, and the emotional tendency or summary can be output to the user, or guidance and suggestions for improving mood can be further output, such as performing one or more physical and / or mental activities, which are not limited here.

[0095] In some embodiments, the body composition sensing module can be electrically connected to the first electrode 30 and the second electrode 40, and obtain the user's body composition signal through the first electrode 30 and the second electrode 40. Based on the body composition signal, the user's body composition measurement results, such as body fat measurement results, can be obtained. The body composition sensing module can be based on a two-electrode mode, a four-electrode mode, or an eight-electrode mode, etc. As an example, the smart ring 100 is also provided with one or more third electrodes for performing body composition measurement. For example, one or more third electrodes can be provided on the outer surface of the outer ring 11. When the user wears the smart ring 100 on one of their fingers, the first electrode 30 and the second electrode 40 contact the skin of the finger wearing the smart ring 100, while the one or more third electrodes can contact the adjacent finger or the user's other hand, thereby achieving body composition measurement using multiple electrodes. As another example, the smart ring 100 can be combined with other electronic devices to achieve body composition measurement. For example, the smart ring 100 can be combined with a wrist-worn device such as a smart watch or a mobile terminal to achieve body composition measurement. For example, a smart watch is provided with at least one third electrode. When a user wears the smart ring 100 and the smart watch at the same time, or the user's finger contacts the first electrode 30 and the second electrode 40 on the smart ring and the at least one third electrode on the smart watch at the same time, the user's body composition measurement can be achieved. In this case, the smart ring 100 can send the detected body composition signal or the signal obtained after one or more processing to other devices that jointly perform body composition measurement, so that the other device can obtain the user's body composition measurement result based on the received signal and the body composition signal detected by itself. Alternatively, the smart ring 100 and other devices can transmit the detected body composition signal or the signal obtained after one or more processing to a mobile terminal or server, so that the mobile terminal or server can obtain the user's body composition measurement result based on the signals received from multiple devices.

[0096] In some embodiments, the temperature sensing module 23 can be electrically connected to at least one of the first electrode 30 and the second electrode 40. The first electrode 30 and / or the second electrode 40 can transmit the skin temperature to the temperature sensing module 23. The temperature sensing module 23 detects the temperature signal and transmits the temperature signal or the signal obtained after one or more processing of the temperature signal to the mobile terminal or server, so that the mobile terminal or server can obtain the user's body temperature monitoring result, wherein the body temperature monitoring result here can be a skin surface temperature monitoring result or a core temperature monitoring result. In this way, when the mobile terminal or server finds that the user's body temperature is abnormal, it can remind the user and further strengthen the monitoring of the user's health, which is conducive to the user to conduct timely and effective health monitoring and timely detection of abnormal health conditions.

[0097] In some embodiments, the charging module 22 can be electrically connected to the first electrode 30 and the second electrode 40, receive power through the first electrode 30 and the second electrode 40, and provide power to the battery assembly 80. Referring to the examples shown in Figures 7 and 8, the charging box 200 may include a base and a charging unit. When the smart ring 100 is placed in the charging box 200, the first electrode 30 and the second electrode 40 are correspondingly connected to the multiple charging terminals 201 of the charging unit, thereby charging the smart ring 100 using the charging box 200. The charging module 22 can be a wired charging module or a wireless charging module, which is not limited here.

[0098] In some embodiments, the smart ring 100 can be manufactured through injection molding. For example, the smart ring 100 can be assembled and manufactured using a jig. Referring to the example shown in Figures 9 to 11 , the jig can include an upper positioning jig 300, a lower positioning jig 400, and a silicone jig 500. The smart ring 100 is manufactured through secondary injection molding.

[0099] First, the upper positioning jig 300 can be used to gas adsorb the first electrode 30 and the second electrode 40, and then the upper positioning jig 300 with the first electrode 30 and the second electrode 40 is placed in the lower positioning jig 400. After the upper positioning jig 300 and the lower positioning jig 400 are used to position the bottom of the first electrode 30 and the second electrode 40, the first glue is dispensed to bond the first electrode 30 and the second electrode 40 together. Alternatively, the bonding can be performed by pouring glue. In other embodiments, the first electrode 30 and the second electrode 40 can be assembled into a whole by a Nano Molding Technology (NMT) injection molding process, and then bonded by pouring glue after positioning by the jig.

[0100] Then, the circuit board 70 and curved battery assembly 80 can be assembled onto the outer ring 11, and the wire 73 can be soldered to the first electrode 30 and the second electrode 40. Finally, a silicone jig 500 can be used in place of the upper positioning jig 300. Epoxy resin can be poured from the silicone jig 500 into the smart ring 100, thereby encapsulating the outer ring 11, electronic component 20, first electrode 30, second electrode 40, circuit board 70, and curved battery assembly 80. After the epoxy resin cures, an isolation ring 60 is formed. The inner wall of the isolation ring 60 protrudes between the first electrode 30 and the second electrode 40 to form two spacers 50.

[0101] In the smart ring 100 provided in the present application, the first electrode 30 and the second electrode 40 are in electrical contact with the charging terminal 201 in the charging box 200 to realize the charging function. The first electrode 30 and the second electrode 40 are in contact with the skin to collect one or more signals from the human body, such as at least one of the skin electrode activity signal, the body composition signal, and the temperature signal. The first electrode 30 and the second electrode 40 can integrate the charging function and the function of collecting human physiological signals, making the smart ring 100 simple in structure and small in size, saving the manufacturing cost of the smart ring 100.
