[0056] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0057] Please refer to the following Figure 1 , Figure 1 A schematic assembly diagram of a wrist-worn device provided by an embodiment of the present application. The wrist-worn device includes a housing 100, a rotating member 200 mounted on the housing 100, a voltage detection circuit, a processor, and a vital sign detection sensor; Figure 1 The dashed line in is the rotation axis when the rotating member 200 rotates relative to the housing 100. The voltage detection circuit, the processor, and the vital sign detection sensor may be inside the housing.

[0058] Specifically, a first conductive electrode 101 and a second conductive electrode 102 that are not electrically connected can be provided on the housing 100. The first conductive electrode 101 and the second conductive electrode 102 can be provided at positions on the housing 100 opposite to the rotating member 200. The rotating member 200 is provided with a conductive portion 201, and other regions of the rotating member 200 except the conductive portion are non-conductive. In this embodiment, multiple gears can be set according to the relative position between the rotating member 200 and the housing 100, and the position when the conductive portion 201 is in contact with both the first conductive electrode 101 and the second conductive electrode 102 can be set as the target gear. When the rotating member 200 rotates relative to the housing 100 to the target gear, the conductive portion 201 shorts the first conductive electrode 101 and the second conductive electrode 102. The number of conductive portions 201 provided on the rotating member 200 in this embodiment is not limited. For example, there can be 2 or more conductive portions 201. By providing multiple conductive portions 201, the convenience of triggering the vital sign data detection process can be improved. Further, the above housing is provided with a first opening and a second opening; when the rotating member rotates to the target gear, the first conductive electrode passes through the first opening and is connected to the conductive portion, and the second conductive electrode passes through the second opening and is connected to the conductive portion.

[0059] As a feasible implementation manner, the processor can be a CPU (Central Processing Unit, central processing unit) or an MCU (Microcontroller Unit, micro control unit). The processor and the vital sign detection sensor can be provided on the main board inside the housing. There can be a voltage detection circuit on this main board. One end of the first conductive electrode and the second conductive electrode is connected to the voltage detection circuit, and the voltage detection circuit can detect the voltage change caused by the short circuit of the first conductive electrode and the second conductive electrode.

[0060] The processor is connected to the voltage detection circuit and is used to judge whether the rotating member rotates relative to the housing to the target gear according to the voltage change; if so, it controls the vital sign detection sensor to collect vital sign data.

[0061] The wrist-worn device provided in this embodiment includes a housing, a rotating member, a processor, a vital sign detection sensor, and a voltage detection circuit. The housing is provided with a first conductive electrode and a second conductive electrode, and the rotating member is provided with a conductive portion. When the rotating member rotates relative to the housing, the conductive portion moves in a position relative to the housing. When the housing rotates to the target gear, the conductive portion can short the first conductive electrode and the second conductive electrode. The voltage detection circuit can detect the voltage change caused by the short circuit of the first conductive electrode and the second conductive electrode, and the processor can judge whether the rotating member rotates to the target gear according to the voltage change detected by the voltage detection circuit, and control the vital sign detection sensor to collect vital sign data after rotating to the target gear. In the above process, by adjusting the gear of the rotating member to start the vital sign data collection process, the convenience of the vital sign data detection process can be improved.

[0062] For different voltage detection circuits, there can be corresponding ways to determine whether the rotating part rotates to the target gear, such as Figure 2 and Figure 3 shown as follows:

[0063] Please refer to Figure 2 , Figure 2 which is a schematic diagram of the principle of a voltage detection circuit provided by an embodiment of the present application. As Figure 2 shown, the voltage detection circuit includes a power supply VCC, a pull-up resistor R11, and a pull-down resistor R21; the first conductive electrode is connected to the power supply VCC through the pull-up resistor R11, and the second conductive electrode R21 is connected to the GND terminal (wire ground terminal) through the pull-down resistor R21; when the first conductive electrode and the second conductive electrode are short-circuited, the end of the pull-up resistor R11 far from the power supply is connected to a preset GPIO (General-purpose input / output) pin of the processor. Correspondingly, the process by which the processor determines whether the rotating part rotates to the target gear relative to the housing according to the voltage change includes: determining whether the rotating part rotates to the target gear relative to the housing according to the level state of the preset GPIO pin. Specifically, when the first conductive electrode and the second conductive electrode are not short-circuited, the level state of the GPIO pin is a high level state; when the first conductive electrode and the second conductive electrode are short-circuited, due to the voltage division of the pull-down resistor, the level state of the GPIO pin becomes a low level state. If the voltage detection circuit shown in Figure 2 is applied, when the processor detects that the GPIO pin changes from a high level state to a low level state, it can be determined that the rotating part rotates to the target gear relative to the housing; when the processor detects that the GPIO pin changes from a low level state to a high level state, it can be determined that the rotating part does not rotate to the target gear relative to the housing.

[0064] In order to improve the accuracy of detecting whether the rotating part rotates to the target gear, the processor can also perform an operation of adjusting the resistance values of the pull-up resistor and the pull-down resistor so that the voltage trigger level threshold of the preset GPIO pin when the first conductive electrode and the second conductive electrode are short-circuited. Correspondingly, the process by which the processor determines whether the rotating part rotates to the target gear relative to the housing according to the level state of the preset GPIO pin includes: determining the level state of the preset GPIO pin; where the level state includes a high level state and a low level state, and the voltage of the preset GPIO pin is greater than or equal to the level threshold in the high level state, and the voltage of the preset GPIO pin is less than the level threshold in the low level state; if the level state is a high level state, it is determined that the rotating part does not rotate to the target gear relative to the housing; if the level state is a low level state, it is determined that the rotating part rotates to the target gear relative to the housing.

[0065] Please refer toFigure 3 , Figure 3 This is a schematic diagram of the principle of another voltage detection circuit provided by an embodiment of the present application. Figure 2 and Figure 3 The circuit structure in is basically the same, except for the connection position between the preset GPIO pin of the processor and the voltage detection circuit. When the first conductive electrode and the second conductive electrode are short-circuited, the end of the pull-up resistor R11 away from the power supply is connected to the preset GPIO pin of the processor; when the first conductive electrode and the second conductive electrode are not short-circuited, the end of the pull-up resistor R11 away from the power supply is not connected to the preset GPIO pin of the processor.

[0066] Specifically, when the first conductive electrode and the second conductive electrode are not short-circuited, the voltage of the GPIO pin is 0V; when the first conductive electrode and the second conductive electrode are short-circuited, due to the voltage division of the pull-down resistor, the voltage of the GPIO pin is greater than 0V. If the voltage detection circuit shown in Figure 3 is applied, when the processor detects that the voltage of the GPIO pin is greater than 0V, it can determine that the rotating part rotates relative to the housing to the target gear; when the processor detects that the voltage of the GPIO pin is 0V, it can determine that the rotating part does not rotate relative to the housing to the target gear.

[0067] Figure 2 and Figure 3 In the corresponding embodiments of , when the housing rotates to the target gear, the conductive part can short-circuit the first conductive electrode and the second conductive electrode. At this time, the pull-down resistor connected to the second conductive electrode divides the voltage, so that the voltage of the preset GPIO pin connected to the first conductive electrode changes. The processor of the wrist-worn device judges whether the rotating part rotates to the target gear according to the voltage change of the preset GPIO pin, and controls the vital sign detection sensor to collect vital sign data after the rotating part rotates to the target gear. In the above process, the acquisition process of vital sign data is started by adjusting the gear of the rotating part, which can improve the convenience of the vital sign data detection process.

[0068] As a further introduction to the corresponding embodiments of , in order to facilitate the user to rotate the rotating part to the target gear, corresponding marks can be set on the rotating part and the housing in this embodiment to indicate the relative positions of the rotating part and the housing. Please refer to Figure 1 , Figure 4 , Figure 4 This is a schematic diagram of a gear mark provided by an embodiment of the present application. Figure 4 In , 401 is the rotation mark of the rotating part, 402 is the gear mark corresponding to the default position of the housing, 403 is the gear mark corresponding to the target position, and 404 is the button of the housing.

[0069] ​If the above-mentioned wrist-worn device is a watch, the rotating part of the watch can be a bezel, the housing and the display screen of the watch are fixed components, and the bezel is assembled to the housing through a positioning connection mechanism such as a buckle and can rotate horizontally relative to the housing and the display screen; there is a rotation mark on the bezel to indicate the rotation position of the bezel; there is a gear mark on the cover glass of the dial display screen or on the watch case to mark the rotation position of the bezel relative to the housing or the dial. The display screen of the watch defaults to display the current time. When the user rotates the bezel to the gear mark, the conductive part on the bezel shorts the first conductive electrode and the second conductive electrode, and at this time, the display screen can display the relevant data of the physical sign data. By rotating the bezel to the target gear, the user can enable the physical sign detection function corresponding to the target gear on the watch, and without operating the touch screen, the physical sign detection can be started to quickly measure the physical signs.

[0070] As a further introduction to Figure 1 the corresponding embodiment, the above-mentioned physical sign detection sensor can be any one or a combination of several sensors such as an ECG sensor, a bioimpedance sensor, and a temperature sensor. If the above-mentioned physical sign detection sensor includes an ECG sensor, the wrist-worn device further includes a third conductive electrode, a fourth conductive electrode, and a fifth conductive electrode; wherein, the third conductive electrode and the fourth conductive electrode are arranged at the wearing contact part of the wrist-worn device, and the fifth conductive electrode is arranged on the rotating part or the button of the wrist-worn device, and the ECG sensor collects ECG data through the third conductive electrode, the fourth conductive electrode, and the fifth conductive electrode. The housing can include an upper shell and a bottom shell, the wrist-worn device can further include a wristband, the third conductive electrode and the fourth conductive electrode can be arranged on the bottom shell or the inner surface of the wristband, and the fifth conductive electrode can be arranged on the rotating part or the button of the wrist-worn device or the upper shell or the outer surface of the wristband. The conductive part is arranged in a preset area on the surface of the fifth electrode close to the housing, and an insulating film is plated on other areas of the surface of the fifth electrode close to the housing except the preset area.

[0071] Please refer to Figure 5 , Figure 5 which is a schematic diagram of the conductive electrode connection method of a wrist-worn device provided by an embodiment of the present application. The wrist-worn device includes a rotating part 510, an insulating partition 520, a housing (including an upper shell 530 and a bottom shell 531), a button 540, a first conductive electrode 550, a second conductive electrode 551, a third conductive electrode 560, a fourth conductive electrode 561, a fifth conductive electrode 562, and a sixth conductive electrode 563 located on the upper shell. When the fifth conductive electrode 562 is arranged on the rotating part 510, an insulating film is plated on the fifth conductive electrode 562, and the conductive part arranged on the rotating part 510 is the area where the insulating film is not plated on the fifth conductive electrode 562, such as the electrode contact point 570 of the fifth conductive electrode. In Figure 5 the example shown, the ECG sensor can use the third conductive electrode 560, the fourth conductive electrode 561, and the fifth conductive electrode 562 to collect ECG data.

[0072] In addition, if the above-mentioned physical sign detection sensor includes a bio-impedance sensor, the bio-impedance sensor can collect impedance data using a third conductive electrode 560, a fourth conductive electrode 561, a fifth conductive electrode 562, and a sixth conductive electrode 563. The third conductive electrode and the fourth conductive electrode are arranged at the wearing contact part of the wrist-worn device, and the fifth conductive electrode and the sixth conductive electrode are arranged at the non-wearing contact part of the wrist-worn device. As a feasible implementation manner, the fifth conductive electrode and the sixth conductive electrode are arranged on the rotating member, an insulating member is arranged between the fifth conductive electrode and the sixth conductive electrode, the conductive part is arranged in a preset area on the surface of the fifth electrode close to the housing, and an insulating film is plated on other areas of the surface of the fifth electrode close to the housing except the preset area. The conductive part arranged on the rotating member 510 is the area of the fifth conductive electrode 562 where the insulating film is not plated, such as the electrode contact 570 of the fifth conductive electrode 562. The sixth conductive electrode 563 can also be provided with an electrode contact 571, and a seventh conductive electrode 552 can also be included on the housing so that impedance data can be collected when the seventh conductive electrode 552 contacts the electrode contact 571. When the rotating member rotates to the target gear, the bio-impedance sensor can collect data of the fifth conductive electrode 562 through the electrode contact 570, and can also collect data of the sixth conductive electrode 563 through the electrode contact 571. The seventh conductive electrode 552 is used to connect the electrode contact 571 and the bio-impedance sensor, and when the rotating member rotates to the target gear, the seventh conductive electrode 552 can contact the electrode contact 571 through the opening of the housing. Through the above method, the biosensor can collect data through the fifth conductive electrode and the sixth conductive electrode only after the rotating member rotates to the target gear, which can avoid malfunction triggering and reduce power consumption.

[0073] If the above-mentioned physical sign detection sensor includes an ECG sensor and a bio-impedance sensor at the same time, the wrist-worn device further includes at least one shared electrode, and both the ECG sensor and the bio-impedance sensor can collect physical sign data through sharing, so as to reduce the number of conductive electrodes of the wrist-worn device. Specifically, the process of the processor controlling the physical sign detection sensor to collect physical sign data includes: connecting the shared electrode to the ECG sensor and controlling the ECG sensor to collect ECG data through the shared electrode; or, connecting the shared electrode to the bio-impedance sensor and controlling the bio-impedance sensor to collect impedance data through the shared electrode.

[0074] Taking the conductive electrodes including the third conductive electrode, the fourth conductive electrode, the fifth conductive electrode, and the sixth conductive electrode as an example, the third conductive electrode, the fourth conductive electrode, and the fifth conductive electrode can be used as the shared electrodes. Specifically, the ECG sensor can measure ECG data through three conductive electrodes: LA (Left Arm), RA (Right Arm), and RLD (Right Leg Driver). Two conductive electrodes, LA and RLD, are placed on the watch bottom case, and the conductive electrode RA is placed on the rotating part or the button. If the user wears the watch on the left hand, the left wrist contacts the conductive electrodes LA and RLD, and the right finger presses the conductive electrode RA. In this way, the ECG sensor can measure the user's ECG data. In this embodiment, the third conductive electrode can be used as the conductive electrode LA, the fourth conductive electrode can be used as the conductive electrode RLD, and the fifth conductive electrode can be used as the conductive electrode RA to realize the detection of ECG data. The bio-impedance sensor measures the human impedance through four conductive electrodes: FIR, FVR, FIL, and FVL. The processor can calculate the physical signs information such as the user's body fat percentage, water percentage, and muscle mass through the body composition algorithm by combining the measured impedance data with information such as the user's age, gender, height, and weight. In this embodiment, the third conductive electrode can be used as the conductive electrode FVL, the fourth conductive electrode can be used as the conductive electrode FIL, the fifth conductive electrode can be used as the conductive electrode FIR, and the sixth conductive electrode can be used as the conductive electrode FVR to realize the detection of impedance data. In addition, in this embodiment, the third conductive electrode, the fourth conductive electrode, the fifth conductive electrode, and the sixth conductive electrode can be used as the shared electrodes. The ECG sensor can collect ECG data using any three of the third conductive electrode, the fourth conductive electrode, the fifth conductive electrode, and the sixth conductive electrode, and the bio-impedance sensor can collect impedance data using the third conductive electrode, the fourth conductive electrode, the fifth conductive electrode, and the sixth conductive electrode.

[0075] The following takes the gear detection circuit of the wrist-worn device including the ECG sensor as an example to illustrate the implementation process of rotation detection. Please refer to Figure 6 , Figure 6 which is a schematic diagram of the principle of a voltage detection circuit provided by an embodiment of the present application. As Figure 6As shown, when the rotating part has not rotated to the target gear position, the first conductive electrode is connected to the VCC power supply through the pull-up resistor R11. The first conductive electrode is also connected to a preset GPIO pin of the processor. At this time, the level state of the first conductive electrode detected by the processor is a high level state. The second conductive electrode is defaultly connected to the GND terminal through the pull-down resistor R21. When the rotating part rotates to the target gear position and the conductive part shorts the first conductive electrode and the second conductive electrode, the level of the preset GPIO pin of the processor is pulled low by the resistor R21. The voltage Vg of the preset GPIO pin is Vg = VCC * (R21 / (R11 + R21)). Before this step, the resistance values of the pull-up resistor R11 and the pull-down resistor R21 can be adjusted so that the Vg voltage value is less than the low voltage trigger level threshold of the GPIO pin (that is, so that Vg is in a low level state and wakes up the processor). When the rotating part rotates back from the target gear position to other gear positions, Vg changes from a low level state to a high level state. After the processor detects that Vg changes to a high level state, it determines that the rotating part has not rotated to the target gear position.

[0076] The third conductive electrode and the fourth conductive electrode of the wrist-worn device can be conductive films plated on the outer surface and the inner surface of the heart rate lens sapphire glass. The outer surface of the heart rate lens is in contact with the skin of the human wrist. The inner surface is connected to the main board through a conductive electrode with good electrical conductivity or other conductive materials. The ECG sensor is located on the main board, so that an electronic path is formed between the skin of the human wrist and the ECG sensor through the third conductive electrode and the fourth conductive electrode.
