[0033] As mentioned above, with the development of technologies related to wearable smart products, users pay more attention to the convenience of wearable electronic devices. As a type of wearable electronic device, smart rings for health monitoring have become a new trend in the wearable electronic device market due to their lightness, non-contact, and continuous measurement. At present, the existing smart rings include: an annular shell and a accommodating cavity, in which a power module and a circuit board are arranged, and the circuit board is provided with a number of path heart rate, blood oxygen, blood pressure, body temperature and other monitoring sensors, so as to monitor the user's vital signs (pulse, blood pressure, body temperature, blood oxygen saturation, etc.). However, the existing monitoring sensors are made of silicon-based hard materials, are heavy in size, and are small in size. In order to increase the signal strength, it is necessary to set a glue-injected bubble-type convex lens above the monitoring sensor, for example: Figure 1 is a schematic diagram of an existing smart ring provided in an embodiment of the present application, such as Figure 1 As shown, the existing smart ring is provided with a glue-injected bubble-type convex lens 102 at a position corresponding to the monitoring sensor 101, resulting in a poor wearing experience for users.

[0034] In an embodiment of the present application, the smart ring includes a shell, a light-emitting unit, a flexible photosensitive unit, a circuit board and a chip. The light-emitting unit can emit sensing light, the flexible photosensitive unit can receive reflected light reflected back by the human body, and generate a sensing signal based on the reflected light. The chip can convert the sensing signal into a digital signal, so that the terminal can identify the vital signs of the human body based on the digital signal. Since the smart ring provided by the present application adopts a flexible photosensitive unit, such as OPD, etc., compared with the silicon-based hard material monitoring sensor used in the prior art, due to the use of a flexible photosensitive unit and the flexible photosensitive unit can change its shape, a flexible photosensitive unit with a larger photosensitive area can be set in the smart ring, and there is no need to set a glue-injected bubble convex lens above the monitoring sensor, which can improve the user's wearing experience.

[0035] The smart ring provided by the present application is described below by way of examples.

[0036] Figure 2 is a schematic diagram of a smart ring provided in an embodiment of the present application, such as Figure 2 As shown, the smart ring includes a housing 201, a light-emitting unit 203, a flexible photosensitive unit 202, a circuit board 204 and a chip 205. The light-emitting unit 203, the flexible photosensitive unit 202, the circuit board 204 and the chip 205 are arranged in the cavity of the housing 201, and the light-emitting unit 203 and the flexible photosensitive unit 202 are electrically connected to the chip 205 through the circuit board 204. The light-emitting unit 203 can emit sensing light to the inside of the human body, and the flexible photosensitive unit 202 can receive the reflected light reflected back from the inside of the human body, and generate a sensing signal according to the reflected light, and the chip 205 can convert the sensing signal into a digital signal and transmit it to the terminal for vital sign recognition.

[0037] The smart ring includes an annular shell 201, and the annular shell 201 is hollow inside to form a receiving cavity. In one example, the shell 201 can be made of metal, such as metal alloy. The light-emitting unit 203, the flexible photosensitive unit 202, the circuit board 204 and the chip 205 are arranged in the cavity of the receiving cavity, and the light-emitting unit 203 and the flexible photosensitive unit 202 are electrically connected to the circuit board 204 respectively. In one example, the light-emitting unit 203 can be integrated on the circuit board 204, and the light-emitting unit 203 can emit sensing light, which can be green light, red light, near infrared light, infrared light and other light of multiple wavelengths. The sensing light penetrates the human body (the finger wearing the smart ring) and irradiates into the human body. The blood and red blood cells in the blood vessels inside the human body can absorb part of the sensing light and reflect part of the sensing light to form reflected light.

[0038] The flexible photosensitive unit 202 can receive reflected light reflected from the human body, for example, reflected light reflected from blood, reflected light reflected from red blood cells, etc. The flexible photosensitive unit 202 can generate a sensing signal according to the reflected light after receiving the reflected light. The chip 205 can receive the sensing signal through the circuit board 204 and convert the sensing signal into a digital signal. The terminal can identify vital signs according to the digital signal, for example, identifying the human body's pulse, blood pressure, body temperature, blood oxygen saturation, etc. The terminal can be an electronic device such as a mobile phone. In one example, the flexible photosensitive unit 202 can be an organic photodiode (OPD), and the OPD can convert the received reflected light into an electrical signal.

[0039] In an embodiment of the present application, the smart ring includes a shell 201, a light-emitting unit 203, a flexible photosensitive unit 202, a circuit board 204 and a chip 205. The light-emitting unit 203 can emit sensing light, the flexible photosensitive unit 202 can receive reflected light reflected by the human body, and generate a sensing signal according to the reflected light. The chip 205 can convert the sensing signal into a digital signal, so that the terminal can identify the vital signs of the human body according to the digital signal. Since the smart ring provided by the present application adopts a flexible photosensitive unit 202, such as OPD, etc., compared with the silicon-based hard material monitoring sensor used in the prior art, due to the use of a flexible photosensitive unit 202 and the flexible photosensitive unit 202 can change its shape, a flexible photosensitive unit 202 with a larger photosensitive area can be set in the smart ring, and there is no need to set a glue-injected bubble convex lens above the monitoring sensor, which can improve the user's wearing experience.

[0040] Figure 3 is a schematic diagram of a flexible photosensitive unit provided in an embodiment of the present application, such as Figure 3As shown, the flexible photosensitive unit 202 includes a first photosensitive unit 2021 and a second photosensitive unit 2022, the second end of the first photosensitive unit 2021 is connected to the first end of the second photosensitive unit 2022, the second end of the second photosensitive unit 2022 is electrically connected to the circuit board 204, the light-emitting unit 203 is arranged on the circuit board 204, and the light-emitting unit 203 is located between the second end of the first photosensitive unit 2021 and the first end of the second photosensitive unit 2022, and the housing 201 between the light-emitting unit 203, the first photosensitive unit 2021, the second photosensitive unit 2022 and the inside of the human body includes a first through hole, and the first through hole is encapsulated by a first transparent encapsulation layer. .

[0041] The first photosensitive unit 2021 and the second photosensitive unit 2022 are connected, and a light emitting unit 203 integrated on the circuit board 204 is arranged between the first photosensitive unit 2021 and the second photosensitive unit 2022, and the second photosensitive unit 2022 is electrically connected to the circuit board 204. When in use, the light emitting unit 203 emits sensing light into the human body, and the first photosensitive unit 2021 and / or the second photosensitive unit 2022 receives the reflected light. It should be understood that Figure 4 is a schematic diagram of a smart ring including a first photosensitive unit and a second photosensitive unit provided in an embodiment of the present application, such as Figure 4 As shown, the first photosensitive unit 2021 and the second photosensitive unit 2022 can be arranged on both sides of the ring, so that the angles of receiving reflected light can be different, for example: Figure 4 The direction of the reflected light indicated by the dotted arrow in the middle can receive reflected light from different directions.

[0042] The corresponding positions on the smart ring housing 201 corresponding to the light-emitting unit 203, the first photosensitive unit 2021 and the second photosensitive unit 2022 may include a first through hole, and the first through hole is located between the light-emitting unit 203, the first photosensitive unit 2021 and the second photosensitive unit 2022 and the inside of the human body. The first through hole is encapsulated by a first transparent encapsulation layer, for example: the first through hole is encapsulated by a transparent material such as resin, so that after the light-emitting unit 203 emits sensing light, the sensing light is emitted from the smart ring through the first transparent encapsulation layer and enters the inside of the human body. After the sensing light is reflected by the inside of the human body to form reflected light, the reflected light can be emitted into the first photosensitive unit 2021 and / or the second photosensitive unit 2022 in the smart ring through the first transparent encapsulation layer.

[0043] In one example, if Figure 3 As shown, the second photosensitive unit 2022 can be electrically connected to the circuit board 204 through a binding wire. In other examples, the second photosensitive unit 2022 can be electrically connected to the circuit board 204 through soldering, conductive adhesive, etc. The way in which the second photosensitive unit 2022 is electrically connected to the circuit board 204 is not limited here.

[0044] It should be noted that the circuit board 204 can be a flexible printed circuit (FPC) or a chip on flex (Chip On Flex, or Chip On Film, COF), so that the circuit board 204 can be set in the annular shell 201 and can be deformed with the shape of the shell 201.

[0045] In the embodiment of the present application, the flexible photosensitive unit 202 includes a first photosensitive unit 2021 and a second photosensitive unit 2022, the first photosensitive unit 2021 and the second photosensitive unit 2022 are connected, and the light-emitting unit 203 is arranged between the first photosensitive unit 2021 and the second photosensitive unit 2022, and the second photosensitive unit 2022 is electrically connected to the circuit board 204. Since the first photosensitive unit 2021 and the second photosensitive unit 2022 are provided, and the first photosensitive unit 2021 and the second photosensitive unit 2022 are flexible photosensitive units 202, they can be bent in the annular shell 201, and reflected light from different angles can be received through the first photosensitive unit 2021 and the second photosensitive unit 2022, and more reflected light can be received. Therefore, the signal strength of the sensing signal generated according to the reflected light is high, which can improve the accuracy of vital sign monitoring.

[0046] Figure 5 is a schematic diagram of another flexible photosensitive unit provided in an embodiment of the present application, such as Figure 5 As shown, the flexible photosensitive unit 202 includes N photosensitive unit groups 2023, and the photosensitive unit group 2023 includes a third photosensitive unit 20231 and a fourth photosensitive unit 20232. The fourth photosensitive unit 20232 in the first photosensitive unit group 2023 is electrically connected to the third photosensitive unit 20231 and the circuit board 204 respectively, and the fourth photosensitive unit 20232 in the Mth photosensitive unit group 2023 is electrically connected to the third photosensitive unit 20231 and the third photosensitive unit in the M-1th photosensitive unit group 2023 respectively. The light unit 20231 is connected, and the third photosensitive unit 20231 and the fourth photosensitive unit 20232 in the N photosensitive unit groups 2023 each include a light-emitting unit 203 arranged on the circuit board 204, and the outer shell 201 between the light-emitting unit 203, the third photosensitive unit 20231 and the fourth photosensitive unit 20232 and the inside of the human body includes a second through hole, and the second through hole is encapsulated by a second transparent encapsulation layer, wherein N is a positive integer greater than or equal to 2, and M is a positive integer greater than 1 and less than or equal to N.

[0047] The flexible photosensitive unit 202 may include multiple photosensitive unit groups 2023, each photosensitive unit group 2023 is provided with a third photosensitive unit 20231 and a fourth photosensitive unit 20232, in the same photosensitive unit group 2023, the second end of the third photosensitive unit 20231 is connected to the first end of the fourth photosensitive unit 20232, the first end of the third photosensitive unit 20231 is connected to the second end of the fourth photosensitive unit 20232 in the previous photosensitive unit group 2023, and the second end of the fourth photosensitive unit 20232 in the first photosensitive unit group 2023 is electrically connected to the circuit board 204.

[0048] The corresponding positions of the light-emitting unit 203, the third photosensitive unit 20231 and the fourth photosensitive unit 20232 on the smart ring housing 201 may include a second through hole, and the second through hole is located between the light-emitting unit 203, the third photosensitive unit 20231 and the fourth photosensitive unit 20232 and the inside of the human body. The second through hole is encapsulated by a second transparent encapsulation layer, for example: the second through hole is encapsulated by a transparent material such as resin, so that after the light-emitting unit 203 emits sensing light, the sensing light is emitted from the smart ring through the second transparent encapsulation layer and enters the inside of the human body. After the sensing light is reflected by the inside of the human body to form reflected light, the reflected light can be emitted into the third photosensitive unit 20231 and / or the fourth photosensitive unit 20232 in the smart ring through the second transparent encapsulation layer.

[0049] The following is an example of N = 2. Figure 5 As shown, when the flexible photosensitive unit 202 includes two photosensitive unit groups 2023, the second end of the third photosensitive unit 20231 in the first photosensitive unit group 2023 is connected to the first end of the fourth photosensitive unit 20232, and the second end of the fourth photosensitive unit 20232 is electrically connected to the circuit board 204. It should be understood that since N=2 at this time, M is a positive integer greater than 1 and less than or equal to N, and M=2 at this time, that is, the second end of the third photosensitive unit 20231 in the second photosensitive unit group 2023 is connected to the first end of the fourth photosensitive unit 20232, and the second end of the fourth photosensitive unit 20232 is connected to M-1, that is, the first end of the third photosensitive unit 20231 in the first photosensitive unit group 2023, and as shown in FIG. Figure 5 As shown, each photosensitive unit group 2023 includes a light emitting unit 203 disposed on a circuit board 204 between the third photosensitive unit 20231 and the fourth photosensitive unit 20232 .

[0050] The following is an example of N=3. Figure 6 is a schematic diagram of another flexible photosensitive unit 202 provided in an embodiment of the present application, such as Figure 6As shown, when the flexible photosensitive unit 202 includes three photosensitive unit groups 2023, the second end of the third photosensitive unit 20231 in the first photosensitive unit group 2023 is connected to the first end of the fourth photosensitive unit 20232, and the second end of the fourth photosensitive unit 20232 is electrically connected to the circuit board 204. It should be understood that since N=3 at this time, M is a positive integer greater than 1 and less than or equal to N, when M=2, that is, the second end of the third photosensitive unit 20231 in the second photosensitive unit group 2023 is connected to the first end of the fourth photosensitive unit 20232. When M=3, the second end of the third photosensitive unit 20231 in the third photosensitive unit group 2023 is connected to the first end of the fourth photosensitive unit 20232, and the second end of the fourth photosensitive unit 20232 is connected to the first end of the third photosensitive unit 20231 in M-1, i.e., the second end of the fourth photosensitive unit 20232 is connected to the first end of the third photosensitive unit 20231 in M-1, i.e., the second photosensitive unit group 2023, and when M=3, i.e., the second end of the third photosensitive unit 20231 in the third photosensitive unit group 2023 is connected to the first end of the fourth photosensitive unit 20232, and the second end of the fourth photosensitive unit 20232 is connected to the first end of the third photosensitive unit 20231 in M-1, i.e., the second photosensitive unit group 2023, and when Figure 6 As shown, each photosensitive unit group 2023 includes a light emitting unit 203 disposed on a circuit board 204 between the third photosensitive unit 20231 and the fourth photosensitive unit 20232 .

[0051] It should be understood that the above two examples are only used as an illustration, and N can be any positive integer greater than or equal to 2. The specific value of N can be set according to the cost and space of the smart ring, and is not specifically limited here.

[0052] Figure 7 is a schematic diagram of a smart ring including N photosensitive unit groups provided in an embodiment of the present application, such as Figure 7 As shown, N photosensitive unit groups 2023 can be set at different positions of the smart ring, and the smart ring can be rotated arbitrarily. After the smart ring rotates, the third photosensitive unit 20231 and / or the fourth photosensitive unit 20232 are still located at the fingertips. The photosensitive unit group 2023 can monitor human vital signs and ensure data accuracy.

[0053] In the embodiment of the present application, the flexible photosensitive unit 202 includes N photosensitive unit groups 2023, each photosensitive unit group 2023 includes a third photosensitive unit 20231 and a fourth photosensitive unit 20232, and a light-emitting unit 203 arranged on the circuit board 204 is included between the third photosensitive unit 20231 and the fourth photosensitive unit 20232, so that the vital signs of the human body can be monitored by the N photosensitive unit groups 2023. Since N photosensitive unit groups 2023 are provided, the vital signs of the human body can be monitored by multiple photosensitive unit groups 2023 when the smart ring rotates. Compared with setting one photosensitive unit group 2023, the vascular area of ​​the finger pulp can be monitored when the smart ring rotates, which can ensure the accuracy of data collection. Since multiple photosensitive unit groups 2023 are provided, when one photosensitive unit group 2023 is damaged, monitoring can continue through other photosensitive unit groups 2023, thereby improving the reliability of the smart ring.

[0054] In one possible implementation, among the N photosensitive unit groups 2023, the photosensitive directions of the third photosensitive units 20231 in at least two photosensitive unit groups 2023 are located on a straight line, or the photosensitive directions of the fourth photosensitive units 20232 in at least two photosensitive unit groups 2023 are located on a straight line, or the photosensitive directions of the third photosensitive units 20231 in at least two photosensitive unit groups 2023 are located on a straight line, and the photosensitive directions of the fourth photosensitive units 20232 are located on the same straight line.

[0055] Among the N photosensitive unit groups 2023, the photosensitive directions of the third photosensitive units 20231 in at least two photosensitive unit groups 2023 are located on the same straight line. The following takes N=2 as an example for explanation.
