Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0053] With the rapid development of smart wearable devices, virtual reality (VR) and augmented reality (AR) technologies, people are paying more and more attention to emerging electronic products such as smart wearable devices. However, due to the inconvenience of using physical keyboards or virtual keyboards, text input on smart wearable devices has always been one of the pain points, resulting in low text input efficiency and high text input error rate when using smart wearable devices, which reduces the user experience.

[0054] To this end, the utility model proposes a wearable component, referring to Figure 1 , the wearable component comprises:

[0055] Wearable carrier 10;

[0056] A communication circuit 20, provided on the wearable carrier 10, and used for communicating with an external smart device;

[0057] The signal acquisition circuit 30 is arranged on the wearable carrier 10. The signal acquisition circuit 30 is used to collect the user's motion data when the user wears the wearable component, and output the motion data to an external smart device through the communication circuit 20.

[0058] In this embodiment, the wearable carrier 10 can be implemented in the form of nail pieces, watches, bracelets, rings, finger rings, gloves, straps, clothing, etc. External smart devices include AR glasses, VR head-mounted display devices, mobile phones, tablets, computers, etc. The communication circuit 20 can be implemented by a wired communication module, such as a LIN communication module, a CAN communication module, an RS485 transceiver chip, etc., and the corresponding bus type is selected according to the communication module. The communication circuit 20 can also be implemented by a wireless communication module, such as a WiFi module, a Bluetooth communication module, a 4G / 5G module, etc. The signal acquisition circuit 30 can be implemented by a motion sensor acquisition circuit, a photoelectric encoder signal acquisition circuit, etc.

[0059] Specifically, the user can wear the wearable component on a certain part of the body, and establish a communication connection between the wearable component and an external smart device. When the user uses the wearable component to click, move, draw, etc., the signal acquisition circuit 30 can obtain the user's motion data and output it to the external smart device through the communication circuit 20. After receiving the motion data output by the signal acquisition circuit 30, the external smart device can restore the user's motion trajectory according to the motion data, thereby realizing the functions of text input and control of the smart device. For example, after the user wears the wearable component and communicates with the smart device, the user can perform text input operations on the smart device through the user's rotation, gestures and other interactive methods, such as performing a nine-square grid input through the part where the wearable component is worn. The smart device restores the user's motion trajectory through the motion data output by the signal acquisition circuit 30, performs a nine-square grid click judgment, and then realizes the text recognition function, improving the accuracy of the text input to the smart device. At the same time, the user can use the wearable component to remotely control the smart home and realize home automation, wherein the smart home includes smart lights, smart air conditioners, curtains, etc. In addition, users can also use simple gestures to control music playback, volume adjustment, song or video switching of smart devices (such as speakers), and control the display of content in VR / AR devices by wearing wearable components, thus improving user convenience and user experience.

[0060] In actual applications, users can wear the wearable component on a flexible part and perform corresponding movements, including clicking, moving, drawing, etc., so that the wearable component can upload the collected motion data to the external smart device, so that the external smart device can restore the user's motion trajectory and implement text input, control and other operations according to the internal control program of the external smart device. In this way, the accuracy of the wearable component's text input or control instructions to the external smart device and the convenience of user use are improved.

[0061] It is understandable that fingers are one of the most flexible organs of human beings, and can quickly complete actions such as clicking, moving, and drawing. At the same time, with the rise of nail art sheets, a variety of styles and designs are available on the market, ranging from simple to gorgeous, including but not limited to bows, hand-painted patterns, 3D printed designs, etc., to meet the needs of different occasions and users' personal styles. Therefore, the wearable carrier 10 can be realized in the form of nail art sheets.

[0062] In one embodiment of the present utility model, the wearable carrier 10 is a sheet carrier, the sheet carrier is a nail art sheet, and the nail art sheet includes:

[0063] A substrate layer, the substrate layer having a first surface and a second surface disposed opposite to each other;

[0064] an adhesive layer, disposed on the first surface;

[0065] The decorative layer is arranged on the second surface.

[0066] In this embodiment, the substrate layer can be made of materials such as thermoplastic elastomer (TPE), acrylic resin (PMMA), polycarbonate (PC), ABS plastic, etc. The decorative layer can be made of materials such as polyurethane resin layer, nail painting glue, printing glue, etc.

[0067] In this embodiment, the wearable carrier is arranged on the substrate layer, the adhesive layer is arranged on the first surface of the substrate layer, and the decorative layer is arranged on the second surface of the substrate layer, wherein the first surface is arranged close to the human nail and the second surface is arranged away from the human nail.

[0068] It is understandable that the adhesive layer is provided with adhesive or double-sided adhesive for attaching the nail art sheet to the human nail. The adhesive can be implemented by using jelly glue, resin glue, etc. In this embodiment, jelly glue, which is a water-soluble environmentally friendly glue, can be used to implement it. It has the characteristics of no odor, suitable for short-term wear of nail art sheets, easy to remove and little damage to human nails. In addition, double-sided adhesive is convenient and fast, and is suitable for temporary or disposable nail art sheets.

[0069] In this embodiment, the shape and size of the substrate layer are compatible with the shape and size of human nails. That is, the shape and size of the nail art sheet wearable carrier can be customized according to the shape and size of the user's nails. In addition, patterns or texts can be drawn on the decorative layer, for example, the pattern desired by the user is attached to the decorative layer through water transfer technology. Optionally, glitter, sequins and other materials can also be sprinkled on the decorative layer to increase the beauty to meet the personalized needs of the user.

[0070] Through the above configuration, the utility model uses the nail art sheet as a wearable component, which can not only serve as an auxiliary input accessory of an external smart device to complete the text input or control work of the smart device, but also increase the diversity of the nail art sheet styles through different colors, patterns, etc., to meet the personalized needs of more users. In addition, the nail art sheet wearable component is easy to wear and easy to operate.

[0071] In another embodiment of the utility model, the wearable component further includes at least one first circuit board, at least one second circuit board and a flexible circuit board;

[0072] The signal acquisition circuit 30 is arranged on any one of the first circuit board and the second circuit board, the communication circuit 20 is arranged on any one of the first circuit board and the second circuit board, and the flexible circuit board electrically connects the first circuit board and the second circuit board.

[0073] In this embodiment, the wearable carrier can be implemented by a sheet carrier such as a nail sheet, a band-aid, or a patch. When the user uses the wearable component, it can be attached to the fingernail or finger by nail glue or medical pressure-sensitive adhesive, and can be used after connecting to the smart device. The first circuit board and the second circuit board can be implemented by a PCB (Printed Circuit Board), such as a metal substrate, a ceramic substrate, and the like. The flexible circuit board (FPC) can be implemented by FPCA (Flexible Printed Circuit Assembly), single-sided FPC, double-sided FPC, multi-layer FPC, and the like.

[0074] Specifically, the wearable component is a nail plate as an example for explanation, refer to Figure 2, the size of the nail sheet needs to be set according to the size of the user's nails, that is, the length x and width y are variable values. Since the nail sheet needs to fit the human nail, it has a certain curvature, so the various electronic components in the wearable component can be arranged on different small-area PCB boards, and then the different PCB boards are electrically connected through FPC. For example, the communication circuit 20 is set on the first PCB board, the signal acquisition circuit 30 is set on the second PCB board, and the first PCB board and the second PCB board are electrically connected through FPC. In this way, the arrangement of devices can be completed in a limited space, and the curvature requirements of the nail sheet can be met, which is more in line with human nails and improves the user experience.

[0075] It can be understood that the rigid-flex PCB combines the stability of the rigid PCB and the bendability of the flexible PCB, and is composed of alternating rigid and flexible circuit layers, which is suitable for complex designs that need to maintain rigidity in specific areas and flexibility in other parts. Therefore, in this embodiment, a rigid-flex PCB can be used to implement the design of the circuit module of the wearable component.

[0076] Through the above settings, considering the bending of the nail art piece, the whole structure has a certain curvature, and it is impossible to use a larger PCB board. Therefore, a soft-hard combination board is adopted, which can be divided into multiple small-area PCB boards. The PCBs are connected by FPC, which realizes bending and folding in a limited space, meeting the miniaturization requirements of wearable components. In addition, the FPC is relatively light and thin, which helps to reduce the overall weight of the nail art piece. The FPC is directly connected to the pads on the PCB board, reducing the use of the connector 40 and reducing the risk of failure caused by looseness or wear of the connector 40, thereby improving the reliability of the wearable component.

[0077] In one embodiment of the present invention, reference Figure 3 , the signal acquisition circuit 30 comprises:

[0078] Main control circuit 31;

[0079] A motion sensor 32, wherein the motion sensor 32 is electrically connected to the main control circuit 31;

[0080] The motion sensor 32 is used to collect the user's motion data when the user wears the wearable component, and output the motion data to the main control circuit 31;

[0081] Among them, the main control circuit 31 and the motion sensor 32 are both arranged on the wearable carrier 10, the communication circuit 20 and the main control circuit 31 are arranged on the first circuit board, and the motion sensor 32 is arranged on the second circuit board.

[0082] In this embodiment, the main control circuit 31 can be implemented by a main controller, such as MCU, DSP (Digital Signal Process), FPGA (Field Programmable Gate Array), PLC, SOC (System On Chip), etc. The motion sensor 32 can be implemented by an accelerometer, a gyroscope, a magnetometer, an infrared sensor, a radar sensor, a photoelectric sensor, etc. It can be understood that the communication circuit 20 can be integrated with the main control circuit 31 in the same integrated circuit to reduce the wiring area of ​​the circuit board and reduce the volume of the wearable component, such as a microcontroller unit (MCU) with integrated Bluetooth Low Energy (BLE) function, i.e., BLE MCU, which combines the traditional microcontroller function with BLE wireless communication technology to achieve low power consumption and high integration. In this embodiment, the wearable component also includes an antenna, which is arranged on the wearable carrier 10, and the antenna is electrically connected to the first circuit board. The Bluetooth low power wireless communication module integrated in the BLE MCU transmits and receives radio signals through the antenna to complete the upload of motion data and the reception of control signals. Wearable components connect and communicate with smart devices through antennas. Wearable components can interact with smart devices efficiently and stably wirelessly while maintaining low power consumption.

[0083] It should be noted that IMU (inertial measurement unit), as a sensor component integrating accelerometer and gyroscope, is not affected by external environmental conditions, such as light, magnetic field or shielding, and can still provide continuous motion data in an environment with poor or no GPS signal (such as indoors, tunnels, high-rise buildings). In addition, IMU can provide high-precision instant motion information, especially for rapid motion changes in a short period of time, such as the measurement of acceleration and angular velocity. It has a fast response speed and high measurement accuracy, and can fully describe the motion state of an object in three-dimensional space, including posture, speed and position. Therefore, in this embodiment, IMU is selected as a telekinetic sensor, and IMU communicates with the main control circuit 31 through the SPI bus, and sends the collected motion data to the main control circuit 31 for processing in real time, so that the main control circuit 31 uploads the collected user's motion data to the smart device to improve the accuracy of the motion data. Among them, the motion data includes at least one of acceleration and angular velocity in three-dimensional space. It can be understood that IMU, as a precision sensor, is sensitive to electromagnetic interference and temperature. Isolating it from the MCU and other active components that generate strong electromagnetic radiation can reduce electromagnetic interference. In addition, the MCU may generate more heat when working under high load. If it is too close to the temperature-sensitive IMU, it may affect the performance of the IMU. Therefore, in this embodiment, the BLE MCU and IMU are set on different PCB boards to improve the accuracy and reliability of the motion data collected by the IMU.

[0084] Specifically, when the user uses the finger wearing the nail art piece to click, draw, slide, etc., the IMU can collect the user's motion data, wherein the motion data includes the acceleration ax, ay, az in the three axes of x, y, and z and the angular velocities wx, wy, and wz in the three axes. And the motion data is output to the main control circuit 31, so that the main control circuit 31 uploads it to the smart device, such as the control device of AR glasses, through the communication circuit 20. The control device of AR glasses integrates the acceleration ax, ay, and az in the three axes of x, y, and z over time to obtain the speed in the three axes of x, y, and z, and then integrates the speed in the three axes of x, y, and z over time to obtain the displacement in the three axes of x, y, and z, and integrates the angular velocities wx, wy, and wz in the three axes over time to obtain the angles in the three axes of x, y, and z. Among them, the z axis is in the same direction as gravity, and the x axis, y axis, and z axis are set in advance by the R&D personnel.

[0085] The specific calculation formula is as follows:

[0086] ∫adt ＝ v;∫vdt ＝ d;∫wdt ＝ r;

[0087] Among them, a is acceleration, v is velocity, d is displacement, w is angular velocity, and r is angle.

[0088] For the XY plane, such as Figure 8 Assuming that the current position is point 1, suppose that after dt time of finger movement, by integrating the acceleration ax and ay in the x and y axis directions twice, the displacement on the x and y axes can be obtained, and the angle of rotation on the XY plane can be obtained by integrating wz. Therefore, the position after movement (i.e. point 2) can be determined. In this way, the movement trajectory of the finger at dt time can be determined, and then the movement trajectory of the user can be restored.

[0089] It should be noted that the granularity of the finger motion trajectory calculation can be adjusted by setting the upper and lower limits of the integral, that is, the smaller the time interval, the more accurate the restoration of the finger motion trajectory. In addition, the main control circuit 31 in the wearable component can also complete the corresponding calculation according to the motion data output by the motion sensor 32 to obtain the user's motion trajectory, and then upload the signal corresponding to the motion trajectory to the smart device (such as AR glasses) via the communication circuit 20, thereby realizing text input or control operations on the AR glasses. Taking into account the power consumption requirements, the auxiliary input accessories of the nail art-type smart device selected in this embodiment only need to be responsible for motion data collection and data uploading, and the smart device performs relevant calculations, thereby reducing the power loss of the wearable component to a certain extent.

[0090] Specifically, after AR glasses restore the finger's motion trajectory based on motion data, they project it onto the XY plane to obtain the starting and ending information of the user's motion trajectory. When using nail art as an auxiliary input accessory for smart devices, gesture calibration is required first, such as Fig. 9As shown, the calibration of the nine-square grid is completed. First, the voice module and display module of the AR glasses can be used to give voice prompts or screen prompts to the user to complete the calibration of the nine-square grid. The default position of the finger is set to the center of the nine-square grid (that is, the position of the number 5). The default position is also defined as the coordinate origin. Then, the user is guided to define the positions of the numbers 1, 3, 7, and 9 in sequence by voice. For example, after the AR glasses use the initial position of the finger (the starting point of the movement) as the center of the nine-square grid, the voice module can be controlled to give a voice prompt: "Please move your finger to the upper left" to complete the calibration of the number 1. Similarly, the coordinate range of each area of ​​the entire nine-square grid input method can be determined. At the same time, the same method can be used to guide the user to define the overall coordinate range of the nine-square grid. After completing the calibration of the nine-square grid, the user's finger can start to move, and the nail art piece uploads the movement data to the AR glasses. When the AR glasses restore the movement trajectory based on the movement data and determine the starting and end positions of the finger movement, the positions of the two adjacent clicks of the finger can be confirmed, so that the nine-key pinyin key can be judged and the alternative characters or alternative words can be displayed. That is, AR glasses can project the nine-square grid and the motion trajectory through the display screen, so that the user can see the corresponding alternative words or alternative words through the AR glasses, and complete the selection among the alternative words or alternative words. For example, click on the area outside the coordinate range of the nine-square grid to select, slide left and right outside the coordinate range of the nine-square grid to switch the selection of the alternative words or alternative words, and then click to enter when you see the alternative words or alternative words you need to select through the display screen of the AR glasses. It should be noted that when the user performs nine-square grid input, if clicks, slides, etc. outside the overall calibration range of the nine-square grid, other instructions will be triggered, such as the switching and input of alternative words or alternative words described above. In order to avoid the user performing corresponding operations outside the overall calibration range of the nine-square grid when entering text, and mistakenly triggering other instructions to reduce the efficiency of text input operations, the smart device can be set to perform voice or screen prompts when it is determined that the user performs invalid operations outside the overall calibration range of the nine-square grid during the text input operation, so as to correct the scope of the user's current operation and improve the accuracy of text input.

[0091] The setting of IMU realizes the accurate collection of motion data of the wearable component worn by the user when moving in three-dimensional space, so that the smart device or the main control circuit 31 can restore the user's motion trajectory to complete the text input of the smart device, thereby improving the accuracy of text input; at the same time, the motion sensor 32 that is susceptible to interference and the main control circuit 31 that is prone to generate heat and electromagnetic radiation are separated on different circuit boards, thereby improving the anti-interference effect of the wearable component and further improving the accuracy of the wearable component's text input or control of the smart device.

[0092] In one embodiment of the present invention, reference Figure 4 , the wearable component comprises:

[0093] Connector 40, used for connecting to the power supply voltage;

[0094] Energy storage circuit 60;

[0095] A voltage conversion circuit 50, wherein a first end of the voltage conversion circuit 50 is electrically connected to the connector 40, a second end of the voltage conversion circuit 50 is electrically connected to the energy storage circuit 60, and a controlled end of the voltage conversion circuit 50 is electrically connected to the main control circuit 31;

[0096] The main control circuit 31 is used to control the voltage conversion circuit 50 to convert the supply voltage and output it to the energy storage circuit 60 when the connector 40 is connected to the supply voltage, so as to charge the energy storage circuit 60; and is also used to control the voltage conversion circuit 50 to convert the voltage of the energy storage circuit 60 and output it to the main control circuit 31 when the connector 40 is not connected to the supply voltage, so as to power the main control circuit 31.

[0097] In this embodiment, the energy storage circuit 60 can be implemented by energy storage elements such as capacitors and inductors, or by flexible batteries, lithium-ion batteries, lithium polymer batteries, etc. The voltage conversion circuit 50 can be implemented by at least one of a rectifier circuit, a filter circuit, an inverter circuit, a buck-boost circuit, or by a voltage conversion chip, such as a buck-boost chip.

[0098] Combined with the contents of the above embodiments, when the nail art piece is used as an input auxiliary accessory of a smart device, it is necessary to have a certain curvature. Therefore, in this embodiment, the energy storage circuit 60 includes a battery, and the battery is a special-shaped battery. Due to the limited volume of the wearable component, a battery with high energy density needs to be selected. The battery is welded on the first circuit board, that is, the battery is welded to the PCB where the BLE MCU is located through a hot bar. The energy storage circuit 60, the voltage conversion circuit 50 and the connector 40 are arranged on the first circuit board. Among them, the connector 40 includes a metal spring or a Pogo PIN connector 40. Taking into account the demand for miniaturization of the nail art piece, the present embodiment uses a compact Pogo PIN connector 40. At the same time, the Pogo PIN connector 40 is designed with a positive force, which can maintain a small change when the compression stroke changes, ensuring a more stable electrical contact, reducing the loosening or falling off of the connection between the wearable component and the smart device, so as to improve the reliability of the charging work.

[0099] Specifically, the voltage conversion circuit 50 is electrically connected to the battery and is responsible for powering the entire wearable component, that is, the output voltage of the battery is used to power multiple circuit modules such as the communication circuit 20, the motion sensor 32IMU, the voltage conversion circuit 50, and the main control circuit 31, and can be connected to the external energy storage module through the Pogo PIN connector 40 to charge the battery of the wearable component. It can be understood that the wearable component also includes a voltage detection circuit or a current detection circuit for detecting the output voltage or output current of the energy storage circuit 60, and outputting a corresponding voltage detection signal or current detection signal to the main control circuit 31. When the main control circuit 31 determines that the energy storage circuit 60 is insufficient in power according to the voltage detection signal or the current detection signal, it can output a corresponding signal to the external smart device through the communication circuit 20, so that the external smart device prompts the user to charge the wearable component in time. Display components such as a display screen and a voice module can also be provided inside the wearable component to perform corresponding prompts when the energy storage circuit 60 is insufficient in power. When the user uses the Pogo PIN connector 40 to access the power supply voltage, the main control circuit 31 controls the voltage conversion circuit 50 to convert the power supply voltage and output it to the energy storage circuit 60 to charge the energy storage circuit 60, thereby avoiding insufficient battery power in the wearable component and causing it to be unable to be used normally.

[0100] It should be noted that the main control circuit 31MCU can read status information from the voltage conversion circuit 50 through the I2C bus, such as the current charging current, battery voltage, and charging status (charging, full, fault, etc.), and then realize the MCU's control over the voltage conversion circuit 50. In this way, the MCU can finely control the charging process of the wearable component to ensure safe and efficient charging of the battery, and can also adjust the charging strategy according to the battery status and user needs, thereby improving the reliability and stability of the charging work of the wearable component.

[0101] Through the above-mentioned setting, power guarantee is provided for the wearable device component, which can ensure the normal operation of each circuit module in the wearable component, thereby improving the reliability of the operation of the wearable device component.

[0102] In another embodiment of the utility model, the wearable component includes a shell, on which a positive contact and a negative contact for electrically connecting to the connector 40 are provided, the energy storage circuit 60, the first circuit board, the second circuit board and the flexible circuit board are all arranged in the shell, the shell includes an inner side surface and an outer side surface, the energy storage circuit 60 is arranged close to the outer side surface, and the first circuit board, the second circuit board and the flexible circuit board are arranged close to the inner side surface.

[0103] In this embodiment, the shell can be made of silicone, polycarbonate (PC), flexible materials, etc. Silicone has the characteristics of softness, good elasticity and high skin compatibility, which can provide good wearing comfort and reduce allergic reactions. PC, as a hard plastic material, has good transparency, impact resistance and weather resistance, and is suitable for making shells that need to protect internal components and have a certain appearance display effect. Flexible materials can be used to make smart nail art sheets that are bendable and fit the shape of nails, which enhances the natural feeling and comfort of wearing.

[0104] refer to Figure 6 and Figure 7 , Figure 6 and Figure 7 The structure diagram and rear view of the nail art sheet wearable component are shown respectively. The Pogo PIN is located in the lower middle of the rear side and can be charged via a dedicated charging cable. The thickness of the whole device can be set according to actual needs. In this embodiment, the thickness z is about 6 mm. Figure 5 This is a cross-sectional diagram of a nail art sheet wearable component. The outermost part is the outer shell, which can be customized into outer shells of different colors according to different aesthetic needs of users. The battery is close to the outer side, and the first circuit board, the second circuit board and the flexible circuit board are arranged close to the inner side, wherein the inner side is closer to the human nail than the outer side. The outer side can be sprayed with different colors and patterns, and the inner side is bonded to the human fingernail. Inside the outer shell from top to bottom are the battery and the hard-soft board. Since the whole nail art sheet has an arc, a curved special-shaped battery is selected. Below the battery are the PCBA and FPCA. Due to the design of the hard-soft board, there is no need to use a large-area PCB. Instead, different devices can be placed on multiple small-area PCB boards, and the device arrangement can be completed in a limited space.

[0105] The setting of the shell gives the wearable component the characteristics of personalized design to meet the aesthetic needs of different groups of people. In addition, the battery uses a special-shaped battery to adapt to the curvature of the nail piece, and the circuit modules of the wearable component are divided into different PCB boards, and the design of a soft and hard combination board is adopted to make the circuit design more compact, which helps to reduce the size of the wearable component, reduce weight, improve wearing comfort and aesthetics, and thus improve user experience.

[0106] In an embodiment of the present invention, there are multiple wearable carriers 10 , and the communication circuit 20 and the signal acquisition circuit 30 are all provided on the multiple wearable carriers 10 .

[0107] Taking the wearable carrier 10 as a sheet carrier as an example, such as a nail sheet input auxiliary accessory, the number of wearable carriers 10 is set according to actual needs. Taking the number of wearable carriers 10 as 5 as an example, the user can wear five nail sheet wearable carriers 10 on different fingernails of one hand or both hands. When the user uses any one of the multiple fingers wearing the nail sheet to perform an action, the signal acquisition circuit 30 in the corresponding nail sheet wearable carrier 10 will collect the motion data of the finger in real time, and upload it to the external smart device through the communication circuit 20 in the wearable carrier 10 corresponding to the finger that issued the action, so that the smart device can obtain the motion trajectory of the finger according to the motion data, and then perform text input, control and other operations on the external smart device.

[0108] It can be understood that the five wearable carriers 10 can upload the real-time collected motion data to the external smart device separately through their respective communication circuits 20; any one wearable carrier 10 can also be selected as the main wearable component, and the remaining wearable carriers 10 are all slave wearable components. In addition to uploading the motion data collected by itself to the smart device in real time through the communication circuit 20, the main wearable component can also receive multiple motion data uploaded by the slave wearable components and upload them to the smart device. Optionally, when the user wears five manicure-style wearable carriers 10 on the fingernails of the five fingers of the same hand, the order of data transmission between the multiple wearable carriers 10 can be freely set, for example, the wearable carrier 10 corresponding to the little finger outputs the motion data to the wearable carrier 10 corresponding to the ring finger, the ring finger collects the motion data of the ring finger in real time, and uploads it together with the motion data of the little finger to the communication circuit 20 of the wearable carrier 10 of the middle finger. Similarly, the wearable carrier 10 on the middle finger uploads the received motion data and the motion data collected by itself to the wearable carrier 10 of the index finger, so that the wearable carrier 10 on the index finger outputs the received motion data and the motion data collected by itself to the wearable carrier 10 corresponding to the thumb, and then the wearable carrier 10 of the thumb uploads the received motion data and the motion data collected by itself to the smart device. Therefore, it is only necessary to communicate the wearable carrier 10 worn by the thumb with the external smart device. When there are multiple wearable carriers 10, compared with each wearable carrier 10 uploading motion data to the smart device individually, the transmission path of the motion data is reduced, the anti-interference and stability of the motion data are improved, and the reliability of the wearable component is improved.

[0109] In practical applications, multiple wearable carriers 10 can be used to collect motion data from different parts of the user to increase the flexibility of the user. In addition, the user can also wear at least two wearable carriers 10 on the same part. The wearable carriers 10 on the same part upload the motion data collected by each to the smart device in real time. The smart device can perform calculations based on multiple motion data of multiple wearable carriers 10 on the same part, such as using the average method, weighted average method, median method and other calculation methods, select a final result as the motion data of the part and restore its corresponding motion trajectory. In this way, the accuracy of the motion data is improved, and the reliability of the work of the smart device components is improved.

[0110] It should be noted that, in one embodiment, the wearable carrier 10 is provided with a processor;

[0111] The processor is electrically connected to the communication circuit 20, and is used to receive external control instructions via the communication circuit 20 and work according to the external control instructions, and is also used to process the motion data and output corresponding control signals to an external smart device via the communication circuit 20.

[0112] Specifically, the processor can be implemented by the main controller described above. Among them, the external control instructions are output by an external intelligent device. The processor can be electrically connected to the communication circuit 20, and receive corresponding external control instructions through the communication circuit 20 and work according to the received external control instructions. For example, the intelligent device can output corresponding control signals to instruct the wearable component to enter the motion monitoring mode, sleep monitoring mode, etc., so as to adjust the working state of the wearable component and the data type collected. It should be noted that the processor can be integrated with the main control circuit 31 and the communication circuit 20 in the same integrated chip to reduce the wiring area and improve the integration of the wearable component.

[0113] In combination with the above embodiments, the processor can be compatible with signal processing functions and control functions. That is, the processor generates a corresponding control signal according to the motion data and outputs it to the external smart device through the communication circuit 20, so that the external smart device works according to the received control signal. Of course, according to the actual application, the processor can also only perform signal processing to reduce power loss. Specifically, the processor can receive the motion data output by the motion sensor 32 and perform corresponding calculations to restore the user's motion trajectory, and upload the control signal corresponding to the motion trajectory to the smart device (such as AR glasses) through the communication circuit 20, thereby realizing text input or control operation of the AR glasses. When the user uses multiple wearable carriers 10, the main wearable component can receive the motion data output from the wearable component and its own motion data, and process all the motion data to restore the corresponding motion trajectory, and then upload it to the external smart device. Considering the power consumption requirements, in this embodiment, the wearable component only needs to be responsible for motion data collection and data uploading, and the smart device performs relevant calculations, which reduces the power loss of the wearable component to a certain extent.

[0114] The processor setting ensures that the wearable component has signal processing capabilities. The processor can filter the original motion data, remove noise or invalid data, and improve the quality of the motion data. In addition, the motion data can be compressed to facilitate efficient transmission of the motion data to the smart device, and the motion data can be encrypted before transmission to improve the security of the motion data transmission process.

[0115] The utility model also proposes a smart device component, which includes a smart device and any one of the wearable components described above, wherein the smart device is communicatively connected with the wearable component.

[0116] It is worth noting that since the smart device component of the present invention is based on the above-mentioned wearable component, the embodiments of the smart device component of the present invention include all technical solutions of all embodiments of the above-mentioned wearable component, and the technical effects achieved are also exactly the same, which will not be repeated here.

[0117] The above description is only an optional embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the inventive concept of the utility model, or directly / indirectly used in other related technical fields are included in the scope of the utility model.
