[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] In related technologies, detection rings are typically worn on the fingers and have multiple advanced sensors built in, enabling real-time monitoring of several key health indicators. For example, they can accurately measure heart rate, helping users understand their heartbeat at any time and detect abnormalities promptly; they can also monitor blood oxygen saturation, providing a reference for respiratory health, and providing effective evidence for users' health management.

[0031] Detection rings typically have multiple transmitters to emit different types of light and multiple receivers to receive different types of light. However, due to the limited space inside the detection ring, the number of transmitters and receivers that can be placed is limited, which restricts the functionality of the detection ring and reduces its applicability.

[0032] The following is combined with Figures 1 to 5 This describes an embodiment of the present application.

[0033] According to embodiments of this application, in one aspect, a detection ring is provided, such as... Figures 1 to 3 As shown, it includes a ring housing 1, a reflected light emitting component 2, a transmitted light emitting component 3, and a light signal receiving component 4, with the specific scheme as follows.

[0034] The ring housing 1 is a light-transmitting plastic housing with a light transmittance of over 80%. The ring housing 1 has a receiving cavity 11. Specifically, the receiving cavity 11 is a housing that extends circumferentially along the ring housing 1. For example, the receiving cavity 11 is an arc-shaped cavity that extends circumferentially along the ring housing 1, or an annular cavity that extends circumferentially along the ring housing 1. The inner annular surface of the ring housing 1 is used to fit on the finger.

[0035] like Figure 3 As shown, the reflected light emitting component 2 can be fixed and snapped into the accommodating cavity 11 by a snap-fit ​​surface (such as a snap-fit ​​groove or snap-fit ​​block); the transmitted light emitting component 3 is fixed and snapped into the accommodating cavity 11 by a snap-fit ​​surface (such as a snap-fit ​​groove or snap-fit ​​block), and is spaced apart from the reflected light emitting component 2.

[0036] like Figure 3As shown, the optical signal receiving component 4 is disposed in the accommodating cavity 11 and close to the reflective light emitting component 2. The optical signal receiving component 4 is used to receive the light signal emitted by the reflective light emitting component 2 that is reflected by the finger, and the light signal emitted by the transmission light emitting component 3 that is transmitted through the finger. That is, the light signal emitted by the reflective light emitting component is received by the optical signal receiving component 4 after being reflected by the finger, and the light signal emitted by the transmission light emitting component is also received by the optical signal receiving component 4 after being transmitted through the finger.

[0037] It is worth noting that the optical signal receiving component 4 is close to the reflected light emitting component 2, meaning that the optical signal receiving component 4 and the reflected light emitting component 2 are arranged adjacent to each other, that is, the distance between the two is relatively small.

[0038] It should be noted that the reflected light reflector, the transmitted light emitter 3, and the optical signal receiver 4 are all existing products, and their specific structures will not be described in detail here.

[0039] In this embodiment, such as Figures 1 to 3 As shown, a reflective light emitting component 2, a transmittance light emitting component 3, and a light signal receiving component 4 are arranged in the accommodating cavity 11 inside the ring housing 1. The light receiving component simultaneously receives the light signal emitted by the reflective light emitting component 2 and reflected by the finger, as well as the light signal emitted by the transmittance light emitting component 3 and transmitted by the finger. This reduces the number of light signal receivers required, reduces the space occupied, provides space for other detection function components, increases the functionality of the detection ring, and improves the applicability of the detection ring.

[0040] Meanwhile, by placing the optical signal receiving component 4 and the reflected light emitting component 2 close together, the space occupied can be further reduced, providing space for the arrangement of other detection function components, increasing the function settings of the detection ring, and improving the applicability of the detection ring.

[0041] In one embodiment, such as Figure 4 As shown, the detection ring also includes a circuit board 5. The circuit board 5 includes multiple rigid segments 51 and at least one flexible segment 52. Specifically, the rigid segment 51 is a PCB (Printed Circuit Board) or other board material with a certain resistance to deformation, and the flexible segment 52 is an FPC (Flexible Printed Circuit) or other board material with a certain deformation capability. The multiple rigid segments 51 are arranged linearly, and any two adjacent rigid segments 51 are electrically connected through a flexible segment 52. The reflected light emitting component 2 and the light signal receiving component 4 are located on one rigid segment 51, and the transmitted light emitting component 3 is located on another rigid segment 51.

[0042] It should be noted that the linear arrangement of multiple rigid segments 51 means that multiple rigid segments 51 are arranged sequentially along a certain linear trajectory, where the linear trajectory can be a straight line or a curve.

[0043] In actual use, the flexible end in the circuit can make two adjacent rigid segments 51 bend relative to each other, thereby arranging the arc-shaped receiving cavity accordingly.

[0044] In this embodiment, such as Figure 4 As shown, the circuit board 5 includes multiple rigid segments 51 and at least one flexible segment 52. Any two adjacent rigid segments 51 are electrically connected through a flexible segment 52, which enables the circuit board 5 to be set in a conformal manner. At the same time, the reflected light emitting component 2 and the light signal receiving component 4 are set on one rigid segment 51, and the transmitted light emitting component 3 is set on another rigid segment 51. The rigid components can reduce the problem of poor contact between the reflected light emitting component 2, the light signal receiving component 4, and the transmitted light emitting component 3 and the circuit board 5 due to abnormal conditions such as vibration and falling, thereby improving the product reliability of the detection ring.

[0045] In one embodiment, such as Figure 4 As shown, at least a portion of the circuit board 5 is arranged in a bent and overlapping manner within the accommodating cavity 11. Specifically, one end of the circuit board 5 is folded and arranged within the ring housing 1, or the middle part of the circuit board 5. Since the space occupied by the functional devices arranged in the thickness direction of the rigid section 51 is small, the space occupied by the circuit board 5 can be reduced by folding and overlapping this part of the circuit board 5.

[0046] In one embodiment, such as Figure 1 As shown, the ring housing 1 includes a first ring segment 12 and a second ring segment 13 along its circumference, and the first ring segment 12 and the second ring segment 13 are elastically telescopically connected; the accommodating cavity 11 includes a first cavity 111, which is located inside the first ring segment 12, and the reflected light emitting component 2, the transmitted light emitting component 3 and the light signal receiving component 4 are all located inside the first cavity 111.

[0047] Specifically, the central angle of the first ring segment 12 is any angle between 180° and 270°, and correspondingly, the central angle of the second ring segment 13 is any angle between 180° and 90°; preferably, under normal circumstances, the central angles of the first ring segment 12 and the second ring segment 13 are both 180°.

[0048] In actual use, since the thickness of different people's fingers is different, when encountering thicker fingers, the elastic connection between the first finger ring segment 12 and the second finger ring can be used to adapt to the thicker fingers.

[0049] In this embodiment, the ring housing 1 is made up of a first ring segment 12 and a second ring segment 13, and the two are elastically connected, so that fingers of different thicknesses can be used, thereby improving the applicability of the ring housing 1.

[0050] In a specific embodiment, such as Figure 3 and Figure 5 As shown, the detection ring also includes at least one elastic telescopic member 6. Specifically, the elastic telescopic member 6 can be a spring, an elastic rubber strip, etc., and the number of elastic telescopic members 6 can be 1 to 3, preferably 2. The accommodating cavity 11 also includes a second cavity 112, which is located inside the second ring segment 13. A part of the elastic telescopic member 6 is located inside the second cavity 112. The two ends of the elastic telescopic member 6 pass through the two ends of the second ring segment 13 and are fixedly connected to the two ends of the first ring segment 12. Specifically, the two ends of the first ring segment 12 are provided with hanging ears (for example, the cylinder to be ringed), and the two ends of the elastic telescopic member 6 are provided with hooks, which are hung on the hanging ears.

[0051] And / or, such as Figure 3 and Figure 5 As shown, both ends of the second ring segment 13 are provided with sliding grooves 131, and the two ends of the first ring segment 12 are slidably connected to the sliding grooves 131 on the two ends of the second ring segment 13.

[0052] In actual use, the two ends of the first ring segment 12 are slidably connected to the sliding grooves 131 at both ends of the second ring segment 13. When the detection ring is put on a thicker finger, it can play a sliding guiding role, making it easy to operate.

[0053] In this embodiment, an elastic telescopic member 6 is provided through the second ring segment 13 to connect with both ends of the first ring segment 12. The structure is simple and can use a small detection ring.

[0054] Meanwhile, the sliding groove 131 enables the sliding guide connection between the first ring segment 12 and the second ring segment 13, facilitating operation and improving the user experience.

[0055] In some embodiments not shown, an annular telescopic component, such as an annular elastic band, can be provided at each end of the first ring to connect to the two ends of the first ring, so as to achieve an elastic connection.

[0056] In one embodiment, such as Figure 3As shown, the detection ring also includes a power supply component 7. The power supply component 7 is disposed in the first cavity 111 or the second cavity 112 by means of snap-fit ​​or adhesive. The power supply component 7 is electrically connected to the reflected light emitting component 2, the transmitted light emitting component 3 and the light signal receiving component 4 through wires. In this embodiment, the power supply component 7 can be arranged in the first cavity 111 or the second cavity 112 according to the actual space arrangement requirements, which can facilitate spatial arrangement.

[0057] In one embodiment, such as Figure 1 As shown, at least one limiting part 14 is provided on the outer ring surface of the ring housing 1. The limiting part 14 is used to limit contact with the finger to prevent the ring housing 1 from rotating. Specifically, there can be one or two limiting parts 14.

[0058] In this embodiment, a limiting part 14 is provided on the outer ring surface of the ring housing 1 to limit contact with adjacent fingers, which can prevent the detection ring from rotating on the fingers, ensure the stability of the circumferential relative position of the detection ring with respect to the detection fingers, improve the stability of the detection waveform, and thus improve the accuracy of detection.

[0059] In a specific embodiment, such as Figure 1 As shown, the outer ring surface of the ring housing 1 is rectangular, and the two opposite surfaces on the outer ring surface are both limiting parts 14. Specifically, the ring housing 1 is square on the outside and round on the inside, with a simple shape, which facilitates the arrangement of power supply components 7, etc.

[0060] In some embodiments not shown, the main body of the ring housing 1 is annular, and one or two sets of limiting protrusions are provided on the outer ring surface of the ring housing 1. Specifically, one set of limiting protrusions includes two limiting protrusions, which respectively contact the back and pad of the adjacent finger to prevent the detection ring from rotating.

[0061] In one embodiment, such as Figure 1 As shown, the part of the inner ring surface corresponding to the reflected light emitting component 2 and the light signal receiving component 4 is flat and is used to contact the fingertip; the part of the inner ring surface corresponding to the transmitted light emitting component 3 is arc-shaped and is used to contact the side of the finger, which facilitates the fixation of the finger and can improve the stability and accuracy of the detection results.

[0062] In one embodiment, such as Figure 1 As shown, a spherical crown protrusion 15 is provided on the inner ring surface of the ring housing 1 at the part corresponding to the reflected light emitting component 2. The spherical crown protrusion 15 protrudes outward toward the center of the inner ring surface. The spherical crown protrusion 15 can act as a lens to focus light and improve the transmission effect.

[0063] The following embodiment will be used to fully illustrate the solution of this application.

[0064] This embodiment provides a detection ring, such as Figures 1 to 3 As shown, it includes a ring housing 1, a reflected light emitting component 2, a transmitted light emitting component 3, an optical signal receiving component 4, a power supply component 7, and a circuit board 5. The specific solution is as follows.

[0065] The ring housing 1 is a light-transmitting plastic housing with a light transmittance of over 80%. The ring housing 1 has a receiving cavity 11. Specifically, the receiving cavity 11 is a housing that extends circumferentially along the ring housing 1. For example, the receiving cavity 11 is an arc-shaped cavity that extends circumferentially along the ring housing 1, or an annular cavity that extends circumferentially along the ring housing 1. The inner annular surface of the ring housing 1 is used to fit on the finger.

[0066] like Figure 3 As shown, the reflected light emitting component 2 can be fixed and snapped into the accommodating cavity 11 by a snap-fit ​​surface (such as a snap-fit ​​groove or snap-fit ​​block); the transmitted light emitting component 3 is fixed and snapped into the accommodating cavity 11 by a snap-fit ​​surface (such as a snap-fit ​​groove or snap-fit ​​block), and is spaced apart from the reflected light emitting component 2.

[0067] like Figure 3 As shown, the optical signal receiving component 4 is disposed in the accommodating cavity 11 and close to the reflective light emitting component 2. The optical signal receiving component 4 is used to receive the light signal emitted by the reflective light emitting component 2 that is reflected by the finger, and the light signal emitted by the transmission light emitting component 3 that is transmitted through the finger. That is, the light signal emitted by the reflective light emitting component is received by the optical signal receiving component 4 after being reflected by the finger, and the light signal emitted by the transmission light emitting component is also received by the optical signal receiving component 4 after being transmitted through the finger.

[0068] It is worth noting that the optical signal receiving component 4 is close to the reflected light emitting component 2, meaning that the optical signal receiving component 4 and the reflected light emitting component 2 are arranged adjacent to each other, that is, the distance between the two is relatively small.

[0069] It should be noted that the reflected light reflector, the transmitted light emitter 3, and the optical signal receiver 4 are all existing products, and their specific structures will not be described in detail here.

The multiple rigid segments 51 are arranged linearly, and any two adjacent rigid segments 51 are electrically connected through a flexible segment 52. The reflected light emitting component 2 and the light signal receiving component 4 are located on one rigid segment 51, and the transmitted light emitting component 3 is located on another rigid segment 51.

[0071] It should be noted that the linear arrangement of multiple rigid segments 51 means that multiple rigid segments 51 are arranged sequentially along a certain linear trajectory, where the linear trajectory can be a straight line or a curve.

[0072] More specifically, such as Figure 4 As shown, at least a portion of the circuit board 5 is arranged in a bent and overlapping manner within the accommodating cavity 11. Specifically, one end of the circuit board 5 is folded and arranged within the ring housing 1, or the middle part of the circuit board 5. Since the space occupied by the functional devices arranged in the thickness direction of the rigid section 51 is small, the space occupied by the circuit board 5 can be reduced by folding and overlapping this part of the circuit board 5.

[0073] More specifically, such as Figure 1 As shown, the ring housing 1 includes a first ring segment 12 and a second ring segment 13 along its circumference, and the first ring segment 12 and the second ring segment 13 are elastically telescopically connected; the accommodating cavity 11 includes a first cavity 111, which is located inside the first ring segment 12, and the reflected light emitting component 2, the transmitted light emitting component 3 and the light signal receiving component 4 are all located inside the first cavity 111.

[0074] Specifically, the central angle of the first ring segment 12 is any angle between 180° and 270°, and correspondingly, the central angle of the second ring segment 13 is any angle between 180° and 90°; preferably, under normal circumstances, the central angles of the first ring segment 12 and the second ring segment 13 are both 180°.

[0075] More specifically, such as Figure 3 and Figure 5As shown, the detection ring also includes at least one elastic telescopic member 6. Specifically, the elastic telescopic member 6 can be a spring, an elastic rubber strip, etc., and the number of elastic telescopic members 6 can be 1 to 3, preferably 2. The accommodating cavity 11 also includes a second cavity 112, which is located inside the second ring segment 13. A part of the elastic telescopic member 6 is located inside the second cavity 112.

Specifically, the two ends of the first ring segment 12 are provided with hanging ears (for example, the cylinder to be ringed), and the two ends of the elastic telescopic member 6 are provided with hooks, which are hung on the hanging ears.

[0076] And / or, such as Figure 3 and Figure 5 As shown, both ends of the second ring segment 13 are provided with sliding grooves 131, and the two ends of the first ring segment 12 are slidably connected to the sliding grooves 131 on the two ends of the second ring segment 13.

[0077] More specifically, such as Figure 3 As shown, the detection ring also includes a power supply component 7. The power supply component 7 is disposed in the first cavity 111 or the second cavity 112 by means of snap-fit ​​or adhesive. The power supply component 7 is electrically connected to the reflected light emitting component 2, the transmitted light emitting component 3 and the light signal receiving component 4 through wires. In this embodiment, the power supply component 7 can be arranged in the first cavity 111 or the second cavity 112 according to the actual space arrangement requirements, which can facilitate spatial arrangement.

[0078] More specifically, such as Figure 1 As shown, at least one limiting part 14 is provided on the outer ring surface of the ring housing 1. The limiting part 14 is used to limit contact with the finger to prevent the ring housing 1 from rotating. Specifically, there can be one or two limiting parts 14.
