[0002] A human physiological monitoring ring primarily monitors physiological indicators such as blood oxygen and heart rate. By wearing the ring on a finger, these indicators can be monitored in real time. In related art, a human physiological monitoring ring uses an internal light source to emit detection light toward the finger, and a light detector receives the detection light reflected by the finger to monitor human physiological indicators.

This external ambient light interferes with the light detector, reducing the accuracy of the light detector's detection of the reflected detection light, and thus reducing the accuracy of the human body detection ring.

[0046] The present application is further described in detail below with reference to Figures 1 to 6 .

[0047] An embodiment of the present application discloses an inner ring assembly 100 .

[0048] Referring to Figures 1-3, an inner ring assembly 100 according to an embodiment of the present application includes an inner ring 10, a circuit board 20, and a conductive assembly 30. The circuit board 20 is disposed outside the inner ring 10, defining a mounting gap 101 between the inner ring 10 and the circuit board 20. After the circuit board 20 and inner ring 10 are connected, components on the circuit board 20 near the inner ring 10 are positioned within the mounting gap 101. This prevents interference between components on the circuit board 20 near the inner ring 10 and the inner ring 10, thereby minimizing malfunction of the circuit board 20 and improving the reliability of the inner ring assembly 100. Furthermore, the circuit board 20 and inner ring 10 can be securely connected by glue potting. After the glue potting is completed, the mounting gap 101 is filled with glue, and the side of the circuit board 20 away from the inner ring 10 is covered with glue. It should be noted that the circuit board 20 is a ring-shaped flexible circuit board 20 and extends along the circumference of the inner ring assembly 100.

[0049] In some specific embodiments, the material of the inner ring 10 may be ceramic, but the present application is not limited thereto. The material of the inner ring 10 may also be titanium, copper, etc.

[0050] Furthermore, the inner ring assembly 100 can also include a support frame 60, and the side of the support frame 60 close to the inner ring 10 defines a accommodating cavity 601, and the circuit board 20 is placed in the accommodating cavity 601, and then the support frame 60 with the circuit board 20 is placed on the outside of the inner ring 10. When assembling the inner ring assembly 100, compared with directly fixing the circuit board 20 to the outside of the inner ring 10, such a setting can reduce the difficulty of assembling the circuit board 20 and the inner ring 10, thereby improving the processing efficiency of the inner ring assembly 100. It should be noted that the support frame 60 is a flexible support frame 60.

[0051] The inner ring 10 is suitable for being placed on the outside of the user's finger. The circuit board 20 is formed with a detection circuit, and a light source 201 and a light detection element 202 are provided on the side of the circuit board 20 close to the inner ring 10. The light source 201 and the light detection element 202 are both located within the installation gap 101. The light source 201 is used to emit detection light to the user's finger, and the light detection element 202 is used to receive the reflected light formed by the detection light reflected on the surface of the user's finger. The detection circuit is suitable for obtaining the user's physiological information based on the detection signal of the light detection element 202. The light source 201 and the light detection element 202 are both communicatively connected to the detection circuit. In some specific embodiments, the light source 201 can be a light emitting diode and the light detection element 202 can be a photodiode, but the present application is not limited thereto. The light source 201 can also be a laser diode, etc., and the light detection element 202 can be a photoconductor, etc.

[0052] Specifically, the light source 201 emits a detection light, which passes through the inner ring 10 and contacts the user's finger. Part of the detection light is absorbed by the user's finger, and the other part is reflected by the user's finger to form a reflected light. The reflected light passes through the inner ring 10 and is received by the light detection element 202 to generate a detection signal. The detection circuit obtains the user's physiological information based on the detection signal of the light detection element 202, thereby achieving the technical effect of obtaining the user's physiological information through the light source 201, the light detection element 202 and the detection circuit.

[0053] Moreover, by setting the light source 201 to different light-emitting diodes, the light source 201 can emit different detection lights, and different detection lights are used to detect different physiological information of the human body. In some specific embodiments, when the light-emitting diode is an infrared light-emitting diode, the detection light can be used to detect blood oxygen saturation, and when the light-emitting diode is a green light-emitting diode, the detection light can be used to detect heart rate. Designers can set the light source 201 to the corresponding light-emitting diode according to usage requirements, thereby improving the usage experience of the inner ring component 100.

[0054] The conductive component 30 is disposed within the mounting gap 101. Along the radial direction of the inner ring component 100, one end of the conductive component 30 is sleeved outside the light detection element 202 and the other end extends toward the inside of the inner ring component 100. The conductive component 30 includes a filter 301 and a first light guide 302. The filter 301 is used to filter light of a preset wavelength, and the first light guide 302 is used to transmit reflected light to the light detection element 202. It should be noted that the preset wavelength is a wavelength other than the wavelength of the detection light emitted by the light source 201, that is, the preset wavelength does not include the wavelength of the detection light. The preset wavelength can be a single wavelength value or a range of wavelength values.

[0055] In some specific embodiments, when the wavelength of the detection light emitted by the light source 201 is a specific wavelength value A, the preset wavelength is a wavelength value range that does not include the specific wavelength value A. When the wavelength of the detection light emitted by the light source 201 is a specific wavelength value range B, the preset wavelength is a wavelength range that does not include the specific wavelength value range B. Specifically, when the wavelength value range of the detection light emitted by the light source 201 is 500 nanometers-600 nanometers, the preset wavelength is a wavelength range that does not include 500 nanometers-600 nanometers.

[0056] Specifically, when the detection light is reflected by the user's finger to form reflected light, the reflected light and the external ambient light will enter the transmission component 30 together, and the filter 301 will filter the light of preset wavelength in the external ambient light. The first light guide 302 transmits the reflected light and the external ambient light filtered by the filter 301 to the light detection component 202, thereby reducing the interference of the external ambient light on the light detection component 202.

[0057] Moreover, in other specific embodiments, along the radial direction of the inner ring assembly 100, the side wall of the inner ring 10 suitable for stopping with the user's finger is provided with a transparent portion opposite to the circuit board 20, the detection light passes through the transparent portion and contacts the user's finger, the reflected light passes through the transparent portion and enters the first light guide 302, and then the first light guide 302 transmits the reflected light to the light detection element 202. Such a setting can make the light detection element 202 be set at a position of the circuit board 20 that is not opposite to the transparent portion, thereby avoiding external ambient light from being directly received by the light detection element 202 as much as possible, thereby improving the accuracy of the inner ring assembly 100 in detecting human physiological information.

[0058] Furthermore, the inner ring assembly 100 also includes a battery and a wireless charging coil. The battery is electrically connected to the circuit board 20 and the wireless charging coil. The battery is used to supply power to the light source 201 and the light detection element 202 of the circuit board 20, and the wireless charging coil is used to charge the battery.

[0059] Therefore, by using the filter 301 to filter the light of preset wavelength in the external ambient light, and using the first light guide 302 to transmit the reflected light and the external ambient light filtered by the filter 301 to the light detection element 202, compared with the existing technology, the interference of the external ambient light on the light detection element 202 can be reduced, thereby improving the accuracy of the light detection element 202 in detecting the reflected light, and further improving the accuracy of the inner ring component 100 in detecting human physiological information.

[0060] 3-5 , in some embodiments of the present application, there is at least one filter 301. When the filter 301 filters light of a single preset wavelength, there may be one filter 301. When the filter 301 filters light within a preset wavelength range, there may be one or more filters 301. In some specific embodiments, the filter 301 may be a filter, but the present application is not limited thereto. The filter 301 may also be a bandpass filter, a low-pass filter, or a high-pass filter. It should be noted that when the filter 301 is a filter, the filter 301 can filter light of a single preset wavelength. When the filter 301 is a bandpass filter and / or a low-pass filter and / or a high-pass filter, the filter 301 can filter light within a preset wavelength range. Designers can configure the filter 301 as a filter and / or a bandpass filter and / or a low-pass filter and / or a high-pass filter according to actual usage requirements, thereby improving the user experience of the inner ring assembly 100.

[0061] In addition, one end of the first light guide 302 is sleeved on the outside of the light detection element 202 and the other end extends toward the inner side of the inner ring assembly 100. Specifically, the end of the first light guide 302 sleeved on the light detection element 202 abuts against the side of the circuit board 20 close to the inner ring 10. That is, the entire light detection element 202 is located inside the first light guide 302. In some specific embodiments, when the side wall of the inner ring 10 suitable for abutting against the user's finger is provided with a transparent portion, the end of the first light guide 302 away from the light detection element 202 abuts against the side of the transparent portion close to the circuit board 20, and the reflected light passes through the transparent portion and enters the first light guide 302, and then the first light guide 302 transmits the reflected light to the light detection element 202. In other specific embodiments, when the side wall of the inner ring 10 suitable for stopping with the user's finger is provided with an avoidance hole 102, the end of the first light guide 302 away from the light detection element 202 passes through the avoidance hole 102 and is suitable for contacting the user's finger, and the reflected light directly enters the first light guide 302, and then the first light guide 302 transmits the reflected light to the light detection element 202.

[0062] Furthermore, in some embodiments of the present application, when the light detection element 202 is not opposite to the transparent part of the inner ring 10 or the avoidance hole 102 of the inner ring 10, the end of the first light guide 302 close to the light detection element 202 is constructed as the exit part 3024, and the end of the first light guide 302 close to the inner ring 10 is constructed as the incident part 3025, and the first light guide 302 also has a conduction part 3026, which is connected between the incident part 3025 and the exit part 3024. The conduction part 3026 is used to conduct the light located at the incident part 3025 to the exit part 3024. Specifically, the reflected light enters the first light guide 302 from the incident part 3025, and is then conducted to the exit part 3024 by the conduction part 3026, and finally is emitted from the exit part 3024 and received by the light detection element 202. In some other embodiments of the present application, when the light detecting element 202 is opposite to the transparent portion of the inner ring 10 or the avoidance hole 102 of the inner ring 10 , the reflected light is conducted to the light detecting element 202 by the first light guiding element 302 .

[0063] The filter 301 can be arranged at the end of the first light guide 302 away from the light detection element 202. When both the reflected light and the external ambient light enter the first light guide 302, the filter 301 filters the light of preset wavelength in the external ambient light, thereby reducing the interference of the external ambient light on the light detection element 202, and further improving the accuracy of the light detection element 202 in detecting the reflected light, which helps to further improve the accuracy of the inner ring component 100 in detecting human physiological information.

[0064] Moreover, in other specific embodiments, the filter 301 may also be arranged at the end of the first light guide 302 close to the light detection element 202, or the end of the first light guide 302 away from the light detection element 202 and the end of the filter 301 close to the light detection element 202 are both provided with filters 301. Designers can arrange the filter 301 at different positions of the first light guide 302 according to actual usage requirements, thereby improving the usage experience of the inner ring assembly 100.

[0065] By sleeved one end of the first light guide 302 on the light detection element 202, and setting the filter 301 at the end of the first light guide 302 away from the light detection element 202, the technical effect of filtering the preset wavelength of the external ambient light and transmitting the reflected light and the filtered external ambient light to the light detection element 202 can be achieved.

[0066] 3 and 5 , in some embodiments of the present application, there are multiple filters 301, and the multiple filters 301 are stacked in sequence on the end of the first light guide 302 away from the light detection element 202. The multiple filters 301 filter multiple lights of a single preset wavelength value or the multiple filters 301 filter lights within a preset wavelength value range. Designers can use multiple filters 301 to filter multiple lights of a single preset wavelength value, or use multiple filters 301 to filter lights within a preset wavelength value range according to usage requirements, thereby improving the usage experience of the inner ring assembly 100.

[0067] Moreover, in the embodiment shown in FIG4 , there are two filters 301 , one of which is a low-pass filter and the other is a high-pass filter, and the two filters 301 together filter light within a preset wavelength range in the external ambient light.

[0068] 5 , in some embodiments of the present application, the first light guide member 302 defines a first light guiding channel 3021, and the first light guiding channel 3021 forms a first opening 3022 at one end of the first light guide member 302 and a second opening 3023 at the other end. The light detector 202 extends into the first opening 3022, and the second opening 3023 is disposed opposite the optical filter 301. Reflected light sequentially passes through the optical filter 301, the second opening 3023, the first light guiding channel 3021, and the second opening 3023 before being received by the light detector 202. Furthermore, in some embodiments of the present application, when the light detector 202 is not opposite the transparent portion of the inner ring 10 or the avoidance hole 102 of the inner ring 10, the first opening 3022 is located in the emission portion 3024, the second opening 3023 is located in the incidence portion 3025, and the first light guiding channel 3021 is located in the transmission portion 3026.

[0069] It should be noted that the first light guide 302 transmits the reflected light to the light detection element 202 through an optical waveguide. The inner layer of the first light guide channel 3021 used to transmit the reflected light is made of a high refractive index material, and the outer side of the inner layer of the first light guide channel 3021 is covered with an outer layer made of a low refractive index material. The first light guide channel 3021 transmits the reflected light through the total reflection effect, and in the process of the reflected light being transmitted to the light detection element 202, the loss of the reflected light can be reduced by utilizing the total reflection effect.

[0070] Therefore, by utilizing the first light guide channel 3021 to transmit the reflected light to the optical detection element 202, the loss of the reflected light in the process of being transmitted to the optical detection element 202 can be reduced, thereby improving the accuracy of the optical detection element 202 in detecting the reflected light, and further improving the accuracy of the inner ring assembly 100 in detecting human physiological information.

[0071] 2 and 3 , in some embodiments of the present application, the conductive component 30 may further include a second light guide 303, which is disposed outside the first light guide 302, and the outer wall of the second light guide 303 may abut against the outer wall of the first light guide 302, or the outer wall of the second light guide 303 may be spaced apart from the outer wall of the first light guide 302. Specifically, in the embodiment shown in FIG4 , the outer wall of the second light guide 303 abuts against the outer wall of the first light guide 302, and along the height direction of the inner ring component 100, the second light guide 303 may be disposed above or below the first light guide 302, wherein the height direction of the inner ring component 100 may refer to the up-down direction in FIG2 .

[0072] Moreover, along the radial direction of the inner ring assembly 100, the end of the second light guide 303 close to the circuit board 20 has a receiving groove 3031, and the light source 201 is completely extended into the receiving groove 3031, that is, the end of the second light guide 303 close to the circuit board 20 is abutted against the circuit board 20, and the other end of the second light guide 303 is extended toward the inner side of the inner ring assembly 100. When the inner ring 10 is provided with a transparent portion, the end of the second light guide 303 away from the circuit board 20 is abutted against the transparent portion. When the inner ring 10 is provided with a avoidance hole 102, the end of the second light guide 303 away from the circuit board 20 passes through the avoidance hole 102 and is suitable for abutting against the user's finger.

[0073] Furthermore, the second light guide member 303 is made of an opaque material, and the second light guide member 303 is used to transmit the detection light emitted by the light source 201 to the user's finger. Specifically, the second light guide member 303 defines a second light guide channel 3032, and the second light guide channel 3032 forms a third open opening 3033 at one end of the second light guide member 303 and a fourth open opening 3034 at the other end. The light source 201 extends into the third open opening 3033, and the fourth open opening 3034 is arranged opposite to the user's finger. When the inner ring 10 is provided with a transparent portion, the fourth open opening 3034 is arranged opposite to the transparent portion of the inner ring 10 and the user's finger. The detection light emitted by the light source 201 passes through the third open opening 3033, the second light guide channel 3032, the fourth open opening 3034 and the inner ring 10 in sequence and contacts the user's finger. When the inner ring 10 is provided with the avoidance hole 102 , the fourth opening 3034 faces the user's finger, and the detection light emitted by the light source 201 sequentially passes through the third opening 3033 , the second light guide channel 3032 and the fourth opening 3034 to contact the user's finger.

[0074] In addition, the second light guide member 303 can avoid the detection light from directly entering the first light guide member 302 in the installation gap 101 as much as possible, thereby avoiding the light detection member 202 from being interfered with by the detection light as much as possible, and further improving the accuracy of the light detection member 202 in detecting the reflected light, which helps to further improve the accuracy of the inner ring assembly 100 in detecting human physiological information.

[0075] Furthermore, the second light guide 303 and the inner ring 10 may be constructed as an integral piece, that is, a side of the inner ring 10 close to the circuit board is provided with the same structure as the second light guide 303 .

[0076] 2-4 , in some embodiments of the present application, there are multiple light sources 201, and any two adjacent light sources 201 are spaced apart along the circumferential direction of the inner ring assembly 100. Furthermore, in the embodiment shown in FIG4 , the multiple light sources 201 may also be spaced apart along the height direction of the inner ring assembly 100. The frequencies of the detection light emitted by at least two of the light sources 201 are different. That is, the at least two light sources 201 emit detection light toward the user's finger at different time intervals to form reflected light at different time intervals. This can reduce the time interval between the two reflected light rays received by the light detector 202, increase the frequency of the detection signal generated by the light detector 202, and further improve the real-time performance of the inner ring assembly 100 in detecting physiological information of the human body.

[0077] Furthermore, the detection light emitted by at least two light sources 201 is different detection light. Different detection light is absorbed by the human finger and reflected to form different reflected light. The light detection element 202 receives different reflected light and generates different detection signals. The detection circuit obtains different physiological information of the user based on the different detection signals generated by the light detection element 202, thereby improving the user experience of the inner ring assembly 100. In some specific embodiments, the detection light can be infrared light or green light. Infrared light is used to detect human blood oxygen information, and green light is used to detect human heart rate information.

[0078] Furthermore, there are multiple second light guide members 303, and the multiple second light guide members 303 are spaced apart along the circumferential direction of the inner ring component 100 and / or the multiple second light guide members 303 can also be spaced apart along the height direction of the inner ring component 100, and the multiple second light guide members 303 are arranged in one-to-one correspondence with the multiple light sources 201.

[0079] 4 and 5 , in some embodiments of the present application, there are multiple light detection elements 202 , which are spaced apart along the circumferential direction of the inner ring assembly 100 , and each light detection element 202 corresponds to at least one light source 201 , that is, each light detection element 202 can correspond to one light source 201 , or each light detection element 202 can correspond to multiple light sources 201 .

[0080] When each light detection element 202 corresponds to a light source 201, the light detection element 202 only receives the reflected light formed by the detection light emitted by the light source 201 corresponding to the light detection element 202, thereby reducing the interference of the reflected light formed by the detection light emitted by the light source 201 that does not correspond to the light detection element 202, and further improving the accuracy of the light detection element 202 in detecting the reflected light.

[0081] When each light detection element 202 corresponds to multiple light sources 201, that is, multiple light detection elements 202 can all receive reflected light formed after the detection light emitted by multiple light sources 201 is reflected, so that the reflected light formed after the detection light emitted by multiple light sources 201 is reflected can be received by the light detection element 202 as much as possible, thereby improving the accuracy of the light detection element 202 in detecting the reflected light, which helps to further improve the accuracy of the inner ring component 100 in detecting human physiological information.

[0082] Designers can correspond each light detecting element 202 to one light source 201 or correspond each light source 201 to multiple light sources 201 according to design requirements, thereby improving the user experience of the inner ring assembly 100 .

[0083] Furthermore, there are multiple filters 301 and multiple first light guides 302, and the multiple filters 301 and multiple first light guides 302 are arranged at intervals along the circumferential direction of the inner ring assembly 100, and the multiple filters 301 and multiple first light guides 302 are arranged in a one-to-one correspondence with the multiple light detection elements 202.

[0084] 3-5 , in some embodiments of the present application, the side wall of the inner ring 10 suitable for stopping with the user's finger is provided with an avoidance hole 102 that passes through the inner ring 10 in the radial direction of the inner ring assembly 100, and the avoidance hole 102 is connected to the installation gap 101. The first light guide 302 and the second light guide 303 both pass through the avoidance hole 102 and are suitable for stopping with the user's finger. Compared with the detection light passing through the inner ring 10 to contact the user's finger, and the reflected light passing through the inner ring 10 to be received by the light detection element 202, such a setting can avoid the detection light and the reflected light from being blocked by the inner ring 10 as much as possible, thereby increasing the amount of reflected light received by the light detection element 202, improving the accuracy of the detection circuit in acquiring human physiological information, and further improving the accuracy of the inner ring assembly 100 in detecting human physiological information.

[0085] Furthermore, when at least one of the first light guide members 302 and the second light guide members 303 is multiple, there are multiple avoidance holes 102, and the multiple avoidance holes 102 are spaced apart along the circumferential direction of the inner ring assembly 100, and the multiple avoidance holes 102 are arranged in a one-to-one correspondence with the multiple first light guide members 302 and / or the multiple second light guide members 303.

[0086] Furthermore, one end of the first light guide 302 suitable for stopping with the user's finger and one end of the second light guide 303 suitable for stopping with the user's finger are both arranged flush with the inner side of the inner ring 10, which can avoid at least one of the first light guide 302 and the second light guide 303 interfering with the user's finger, causing the user to be unable to wear the inner ring assembly 100.

[0087] 3 and 5 , in some embodiments of the present application, the inner ring assembly 100 further includes: a seal 40, which is disposed in the installation gap 101, one end of the seal 40 being disposed in the avoidance hole 102 and used to seal the avoidance hole 102, and the other end being sleeved on the outside of the first light guide 302 and the second light guide 303. This arrangement can prevent liquid from the external environment from entering the installation gap 101 as much as possible, thereby preventing liquid from the external environment from entering the circuit board 20 and causing the circuit board 20 to fail to work, thereby improving the working reliability of the inner ring assembly 100. It should be noted that the seal 40 is made of a highly transparent material, and both the detection light and the reflected light can pass through the seal 40.

[0088] Furthermore, the seal 40 can be made by glue pouring. When the circuit board 20 and the inner ring 10 are fixedly connected by glue pouring, the glue used for glue pouring seals the avoidance hole 102 and solidifies to form the seal 40. It should be noted that the glue used for glue pouring is a transparent material, and both the detection light and the reflected light can pass through the glue used for glue pouring.

[0089] Based on this, the present application further discloses a human physiological monitoring ring 200. Referring to FIG6 , the human physiological monitoring ring 200 according to the embodiment of the present application includes: an outer ring 50 and an inner ring assembly 100. Along the radial direction of the human physiological monitoring ring 200, the outer ring 50 is detachably connected to the outer side of the inner ring assembly 100. The inner ring assembly 100 is used to monitor human physiological information. The inner ring assembly 100 is the inner ring assembly 100 described in the above embodiment. It should be noted that in some specific embodiments, the outer ring 50 and the inner ring assembly 100 can be connected by bonding, and the outer ring 50 and the inner ring assembly 100 can be separated after the human physiological monitoring ring 200 is heated. The material of the outer ring 50 can be gold, but the present application is not limited thereto. The material of the outer ring 50 can also be titanium and transparent resin, etc.

[0090] According to the human physiological monitoring ring 200 described in the embodiment of the present application, the outer ring 50 is detachably connected to the outer side of the inner ring component 100. By utilizing the filter 301 in the inner ring component 100 to filter the light of a preset wavelength in the external ambient light, and utilizing the first light guide 302 to transmit the reflected light and the external ambient light filtered by the filter 301 to the light detection component 202, compared with the prior art, the interference of the external ambient light on the light detection component 202 can be reduced, thereby improving the accuracy of the light detection component 202 in detecting the reflected light, and further improving the accuracy of the inner ring component 100 in detecting human physiological information.

[0091] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
