Description

Technical Field

[0001] The present invention relates to the field of intelligent wearable technology, and in particular to a wearable device, a wearable accessory and a wearable host. Background Art

[0002] With the rapid development of wearable devices, integrated health monitoring functions have become an important trend in this field. For example, wearable devices such as smart bracelets and smart watches can monitor key physiological parameters such as heart rate, blood oxygen saturation and blood pressure in real time through PPG (Photoplethysmography) technology. PPG technology is based on the changes in light propagation in the blood, and obtains physiological data by analyzing the changes in the amount of light absorbed by substances in the blood.

[0003] Existing wearable devices include LED light-emitting components and sensors. When the wearable devices are worn, the LED light-emitting components and sensors are located on the same side of the wrist. The LED emits light of a specific wavelength, which is reflected after hitting the skin and tissue. The reflected light is then received and analyzed by the sensor to assess health status.

[0004] However, this reflective PPG technology has high requirements for optical path design. Deviations in the assembly of LED light-emitting components and sensors will affect the reflected light received by the sensor. In addition, reflective PPG is greatly affected by the absorption of light by substances in the blood, and the amount of light that can be reflected is relatively limited, resulting in low accuracy in wearable device monitoring of user physiological parameters, affecting the user experience.

[0039] The present invention provides a wearable device 1.

[0040] Combination Figure 1 and Figure 2As shown, in one embodiment of the present invention, the wearable device 1 includes a wearable item 10 and a detection component 20; the wearable item 10 can be enclosed to form a wearing opening 13 for the wearer's limbs to pass through; the detection component 20 includes a light emitter 22 and a light sensor 21, and the light emitter 22 and the light sensor 21 are both arranged on the wearable item 10; when the wearing opening 13 is formed, the light emitting side of the light emitter 22 faces the light receiving side of the light sensor 21, and the light sensor 21 is configured to receive the light signal emitted by the light emitter 22 after passing through the wearer's limbs.

[0041] In this embodiment, the wearable device 1 can be an intelligent wearable device worn on the wrist, arm, thigh, calf or ankle and other limbs. In order to facilitate the description of the technical solution of the present application, the following description is only based on the way in which the wearable device 1 is worn on the wrist, and other wearing methods are similar, and no further elaboration is made here. The wearable part 10 can be an integrally formed structure, and a wearing opening 13 is formed, or it can include a connected strap 11 and a main body 12, and the strap 11 and the main body 12 are buckled on the limbs to form a wearing opening 13. In both ways, the wearable device 1 can be worn on the user's wrist, thereby ensuring the consistency and accuracy of data collection during the detection process. In addition, due to the difference in wrist size of different users, the diameter of the wearing opening 13 of the wearable part 10 can be adjusted to accommodate a wider range of people. For the wearing opening 13 formed by integral molding, the wearable part 10 can be at least partially set to an elastic and retractable structure to achieve the adjustment of the diameter of the wearing opening 13. As for the wearing opening 13 formed by the buckling of the strap 11 and the main body 12, the strap 11 is designed to include a belt-like structure with multiple fine-tuning holes. The wearer can adjust the diameter of the wearing opening 13 formed between the strap 11 and the main body 12 by pressing or buckling the holes at specific positions.

[0042] In the detection component 20, the light emitter 22 uses a light source of a specific wavelength that is harmless to the human body. The light emitter 22 can be a light-emitting element such as LED, OLED, etc. The wavelength of light emitted by the light emitter 22 can be infrared light or near-infrared light. These wavelengths of light can better penetrate the skin and have a higher sensitivity to the components in the blood, which helps to obtain more accurate physiological parameter information. The light sensor 21 is a photoelectric conversion element, such as a phototransistor or a photodiode, which can convert the received light signal into an electrical signal.

[0043] The light emitter 22 and the light sensor 21 are both arranged on the wearable device 10, and when the wearing opening 13 is formed, the light emitter 22 and the light sensor 21 are both located on the side of the wearable device 10 facing the wearing opening 13, that is, facing the wrist of the wearer. The light emitting side of the light emitter 22 is the side from which the light of the light emitter 22 is emitted, and the light receiving side of the light sensor 21 is the side from which the light is received. When the wearing opening 13 is formed, the light emitting side of the light emitter 22 faces the receiving side of the light sensor 21. Such a layout allows the light emitted by the light emitter 22 to penetrate the wrist tissue of the wearer and reach the light sensor 21. The light sensor 21 receives and analyzes the changes in the light signal, and converts it into an electrical signal, which is then output to the processing unit 23 of the wearable device 10. The processing unit 23 can calculate and obtain the user's physiological parameters (such as heart rate parameters, blood oxygen parameters, respiratory rate parameters, etc.) based on the electrical signal of the light sensor 21. Since the present application adopts the transmissive PPG technology, the interference factors of the position accuracy of the light emitter 22 and the light sensor 21 on the reflection path, as well as the interference factors of the light absorption by blood or tissue affecting the reflection of light are reduced, thereby improving the accuracy of the detection data.

[0044] In order to further improve the signal quality, a filtering circuit is integrated inside the light sensor 21, which can effectively remove the noise interference caused by ambient light and other non-target light sources, ensuring that the final physiological parameter data is more accurate.

[0045] The wearable device 1 provided in this embodiment sets the light emitter 22 to emit light toward the light sensor 21, so as to achieve accurate monitoring of the user's physiological parameters. Compared with the traditional reflective solution, the present invention does not require the design of a complex reflective light path, which reduces the difficulty of assembly and also avoids the problem of inaccurate measurement results due to poor reflection effects of blood or tissue. Therefore, the technical solution provided in this embodiment improves the accuracy of the wearable device 1 in monitoring the user's physiological parameters and improves the user's experience.

[0046] Combination Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the wearable device 10 includes a strap 11 and a main body 12 connected to each other, and the strap 11 and the main body 12 are enclosed to form a wearing opening 13;

[0047] The light sensor 21 is disposed on a side of the main body 12 facing the wearing opening 13 , and the light emitter 22 is disposed on a side of the strap 11 facing the wearing opening 13 .

[0048] In this embodiment, the main body 12 is the main component of the wearable device 1. For example, when the wearable device 1 is a watch, the main body 12 is a dial; the strap 11 is an accessory for wearing the main body 12 on the user's wrist. For example, when the wearable device 1 is a watch, the strap 11 is a watch strap. The strap 11 and the main body 12 can be detachably connected by means of magnetism or buckles, so that the two can be closely connected and easy to disassemble and maintain. The strap 11 can be provided with a plurality of magnetic points or buckle points or partially provided with an elastic and retractable structure, so that the wearer can flexibly adjust the wearing tightness according to the size of his or her wrist, thereby ensuring that the device is always in the best fit.

[0049] As a component that converts optical signals into electrical signals, the optical sensor 21 needs to be connected to the processing unit 23 in communication, so as to process the electrical signals output by the optical sensor and obtain the physiological parameters of the user. Therefore, the circuit layout of the optical sensor 21 is more complicated than that of the optical transmitter 22. In addition, since the processing unit 23 and other display or power supply related components occupy a large volume, in order to improve the integration of the device, the processing unit 23 needs to be set in the main body 12. Therefore, in this embodiment, the optical sensor 21 is set on the main body 12 to facilitate the circuit connection of the optical sensor 21 with the processing unit 23 or other power supply or display related components.

[0050] The circuit connection of the light emitter 22 is relatively simple. It is installed on the strap 11 so that the light emitter 22 and the light sensor 21 are not located in the same plane, thereby making it easier to point the light-emitting surface of the light emitter 22 to the light sensor 21 in the main body 12.

[0051] In this embodiment, the light emitter 22 and the light sensor 21 are respectively arranged on the strap 11 and the main body 12, so that the light emitter 22 and the light sensor 21 always maintain a fixed working distance and angle, and even if the strap 11 is slightly displaced during wearing, it will not affect the alignment relationship between the two. This stable optical path greatly improves the detection accuracy, especially when used in dynamic environments, such as sports or daily activities, and can continuously obtain high-precision physiological parameter data. Moreover, this layout method no longer requires a complex reflective optical path design. It only needs to ensure that the light-emitting surface of the light emitter 22 faces the light sensor 21, which makes it easier to achieve precise positioning during assembly, thereby simplifying the assembly process and reducing the difficulty of manufacturing.

[0052] Combination Figure 1 and Figure 3 As shown, in one embodiment of the present invention, both ends of the strap 11 are bent to form a bending portion 112, the two bending portions 112 are connected to the main body 12, the light emitter 22 is disposed on the side of the bending portion 112 facing the wearing opening 13, and the light sensor 21 is disposed at one end of the main body 12 close to the bending portion 112.

[0053] In this embodiment, the design of the bending portion 112 and the position design of the light sensor 21 and the light emitter 22 shorten the distance between the light emitter 22 and the light sensor 21, and reduce the transmission distance of the light. In other embodiments, the light emitter 22 and the light sensor 21 are respectively arranged on opposite sides of the wearable device, which requires the light to penetrate the entire wrist, which not only increases the length of the optical path and reduces the light penetration, but also causes more scattering and refraction, thereby affecting the detection accuracy. In this embodiment, by arranging the light emitter 22 at the bending portion 112, that is, Figure 3 As shown, the light emitter 22 is closer to the light sensor 21, the optical path is reduced, and the light emitted by the light emitter 22 penetrates one side of the wrist where the bones and tissues are thinner. Therefore, this design scheme can improve the transmittance of light, thereby improving the accuracy of the detection component 20 in monitoring the user's physiological parameters, thereby improving the detection accuracy.

[0054] In addition, the design of the bent portion 112 enables the strap 11 to better fit the curve of the wearer's wrist, increasing the comfort when worn, while also reducing the displacement caused by the wearer's activities, thereby maintaining a stable light transmission path.

[0055] Combination Figure 3 As shown, in one embodiment of the present invention, the detection component 20 includes two light sensors 21 and two light emitters 22. The two light emitters 22 are respectively disposed at two bending portions 112, and the two light sensors 21 are respectively disposed at two ends of the main body 12 close to the two bending portions 112. The light emitting side of each light emitter 22 is arranged toward the light receiving side of an adjacent light sensor 21.

[0056] In this embodiment, two light emitters 22 and two light sensors 21 are provided, and each light emitter 22 forms a group with a light sensor 21. The light emitter 22 and the light sensor 21 in each group form an independent optical path. In this way, two independent groups of detection data can be obtained, thereby realizing mutual verification and review of the data.

[0057] Specifically, two groups of light emitters 22 and light sensors 21 can simultaneously obtain two groups of data on the same physiological parameter. If the two groups of data are highly consistent, the measurement result is reliable; if there is a difference, and the difference exceeds the preset threshold, the processing unit 23 takes the average value of the two as the physiological parameter data monitored by the detection component 20; if the physiological parameters detected by a certain group of light emitters 22 and light sensors 21 continue to exceed the health index range, the processing unit 23 uses the abnormal physiological parameter data as the final monitoring result. By setting up two groups of light emitters 22 and light sensors 21, the errors that may occur in single-point measurement can be effectively reduced, and the accuracy and reliability of the overall measurement can be improved.

[0058] In addition, even if one set of light emitters 22 or light sensors 21 fails, the other set of light emitters 22 or light sensors 21 can continue to work to ensure that the device does not fail completely, thereby ensuring the continuation of the continuous monitoring function. This is especially important for users who wear the device for a long time and rely on it for health management.

[0059] In one embodiment of the present invention, the detection component 20 includes two light emitters 22 . The two light emitters 22 are both disposed on the same bending portion 112 , and the light emitting sides of the two light emitters 22 are both disposed toward the light receiving side of the light sensor 21 .

[0060] In this embodiment, by concentrating two light emitters 22 on the same bending portion 112 and making them both emit light toward the light sensor 21 located at one end of the main body 12 close to the bending portion 112, a single light sensor 21 can receive light signals from the two light emitters 22 and obtain two sets of user physiological parameter monitoring data, thereby improving the monitoring accuracy.

[0061] The two light emitters 22 on the same bend 112 can be arranged side by side, vertically, or staggered. For example, when the two light emitters 22 are arranged vertically, the two light emitters 22 are spaced apart in the vertical direction on the bend 112. This layout increases the number of light paths, allowing the light sensor 21 to receive light signal data at different positions through the wrist. For example, the upper light emitter 22 may be more likely to penetrate the surface tissue, while the lower light emitter 22 can better capture information about deep blood vessels. This helps to improve the resolution of multi-layer structures (such as vascular networks at different depths under the skin), thereby providing users with richer physiological parameter data.

[0062] In one embodiment of the present invention, at least one side of the light emitter 22 facing the wearing opening 13 is made of a flexible material.

[0063] In this embodiment, at least one side of the light emitter 22 facing the wearing opening 13 can be made of a flexible material that is soft, elastic, or has a certain degree of deformation ability and has a good light transmittance effect, such as silicone or TPU (thermoplastic polyurethane). The surface of the light emitter 22 made of flexible material is smoother and softer, making the wearing process more comfortable and smooth, and at the same time making the contact between the light emitter 22 and the wearer's skin more natural and fit.

[0064] The flexible material allows the light emitter 22 to slightly deform with the wearer's movements to a certain extent, thereby reducing the pressure on the skin and avoiding discomfort or indentations caused by long-term wearing. In addition, the flexible material can also act as a buffer, reducing the impact of external impact on the light emitter 22 and improving the durability of the device.

[0065] Furthermore, a Fresnel pattern or a focusing lens is provided on the light-emitting side of the light emitter 22 to help the light emitter 22 focus light and increase the penetration performance of light into the skin.

[0066] Combination Figure 2 As shown, in one embodiment of the present invention, a mounting groove 111 is formed on one side of the strap 11 facing the wearing opening 13 , and the light emitter 22 is embedded in the mounting groove 111 .

[0067] In this embodiment, the size and shape of the mounting groove 111 are adapted to the light emitter 22, so that the light emitter 22 can be stably fixed on the strap 11 without loosening or displacement. And the setting of the mounting groove 111 enables the light emitter 22 to be embedded in the strap 11, thereby avoiding the problem that the light emitter 22 protrudes from the surface of the strap 11 and causes discomfort to the user, thereby improving the wearing comfort. At the same time, this embedded design makes the appearance of the wearable device 1 more concise and smooth, without abrupt parts affecting the overall aesthetics. In addition, the mounting groove 111 provides physical protection for the light emitter 22 to prevent it from being damaged by external collision or friction, thereby extending the service life of the light emitter 22. In addition, the embedded design also simplifies the assembly process of the light emitter 22. The light emitter 22 only needs to be inserted into the pre-designed mounting groove 111 to complete the fixation, thereby improving production efficiency, reducing assembly difficulty, and reducing possible manual errors, so that light can pass through the wrist and be received by the light sensor 21, thereby further improving the accuracy of the detection component 20 in monitoring the user's physiological parameters.

[0068] Combination Figures 2 to 4 As shown, in one embodiment of the present invention, the main body 12 includes a shell 122, a circuit board 124 and a display component 121. The shell 122 forms a accommodating cavity 125. The circuit board 124 is disposed in the accommodating cavity 125 and is electrically connected to the light emitter 22, the light sensor 21 and the display component 121. Both ends of the shell 122 are connected to the strap 11, and the display component 121 is disposed on the outer wall of the shell 122.

[0069] In this embodiment, the shell 122 is a component of the main external structure of the main body 12, and plays a role in protecting the internal electronic components and other parts; the two ends of the shell 122 are connected to the strap 11 by a detachable manner such as plug-in and snap-on, and can also be integrally formed with the strap 11 or fixedly connected by welding to ensure a close fit between the two.

[0070] The circuit board 124 integrates electronic components, such as memory, sensor interface, etc., and the processing unit 23 is also arranged on the circuit board 124 and is responsible for processing and transmitting data. A closed accommodating cavity 125 is formed inside the housing 122 for installing the circuit board 124 and other key components. Of course, the accommodating cavity 125 can also be formed by the housing 122 and the display component 121. The accommodating cavity 125 has good sealing performance and can effectively prevent external pollutants such as moisture and dust from entering, so that the wearable device 1 has good waterproof and dustproof effects.

[0071] The display component 121 includes a display surface 12a board and a circuit connecting the display surface 12a board and the circuit board 124. The display surface 12a board adopts a high-resolution display screen, such as an OLED or AMOLED screen, which can clearly display a variety of information such as heart rate and blood oxygen saturation. In addition, the display surface 12a can also integrate a touch function, so that the user can browse and manage health data through simple touch operations.

[0072] The circuit board 124 is provided with a processing unit 23, which is used to execute complex algorithms, analyze the data collected by the light sensor 21 in real time, and calculate accurate physiological parameter values. These data can not only be directly displayed on the screen of the main body 12, but also be sent to the user's smartphone or other terminal device through a wireless communication module (such as Bluetooth, Wi-Fi) for further viewing and recording.

[0073] Combination Figure 2 As shown, in one embodiment of the present invention, the housing 122 is provided with a light inlet 122a communicating with the accommodating cavity 125, a part of the structure of the light sensor 21 is located in the accommodating cavity 125, and the light receiving side of the light sensor 21 is exposed at the light inlet 122a.

[0074] In this embodiment, the light sensor 21 is disposed in the accommodating cavity 125 rather than on the outer surface of the shell 122, which effectively avoids the protrusion problem of the light sensor 21. In other embodiments, the light sensor 21 is disposed on the outer surface of the shell 122, which is easy to cause local protrusions, causing discomfort to the user, especially during long-term wearing, which may cause indentations or friction pain. However, this embodiment ensures the flatness of the surface of the strap 11 by disposing at least part of the structure of the light sensor 21 in the accommodating cavity 125, providing a more comfortable and natural wearing experience. At the same time, the light inlet 122a opened on the side of the shell 122 facing the wearing opening 13 ensures that the light passing through the wrist can be incident on the receiving side of the light sensor 21 through the light inlet 122a. It can be understood that when two light sensors 21 are provided, two light inlets 122a are also provided.

[0075] Combination Figure 2As shown, in one embodiment of the present invention, the detection component 20 further includes an optical lens 24. The optical lens 24 is located on the light receiving side of the light sensor 21 and covers the light entrance 122a.

[0076] In this embodiment, the optical lens 24 can correct the light path, reduce scattering and refraction, and make the light enter the light sensor 21 more concentratedly. In addition, the optical lens 24 is blocked at the light inlet 122a, so that the accommodating cavity 125 forms a closed space, effectively blocking external pollutants (such as moisture and dust) from invading the accommodating cavity 125, and protecting the safety of the circuit board 124 and other sensitive electronic components. This closed design enhances the waterproof and dustproof effects of the wearable device 1, enabling it to work stably in various environments.

[0077] The optical lens 24 is made of a high light transmittance material, such as glass or transparent acrylic and other plastics, and has good optical properties. The surface of the optical lens 24 is provided with Fresnel patterns, which are used to converge light to increase the intensity of the light signal received by the light sensor 21, thereby improving the physiological parameter monitoring accuracy of the detection component 20. Of course, in other embodiments, the optical lens 24 can also be set as a focusing lens, which can also achieve the above-mentioned function of converging light.

[0078] Combination Figure 2 As shown, in one embodiment of the present invention, a power supply terminal 123 electrically connected to the circuit board 124 is provided at one end of the shell 122, and a receiving terminal electrically connected to the optical transmitter 22 is provided at one end of the strap 11, and the power supply terminal 123 is electrically abutted with the receiving terminal.

[0079] In this embodiment, a power supply terminal 123 is provided at one end of the housing 122, and the power supply terminal 123 is electrically connected to the circuit board 124 in the accommodating cavity 125. At the same time, a receiving terminal is provided at one end of the strap 11, and the receiving terminal is electrically connected to the optical transmitter 22, so that the optical transmitter 22 can receive power provided by the circuit board 124 through the cooperation of the receiving terminal and the power supply terminal 123. Since the optical transmitter 22 is arranged in the mounting groove 111 of the bending portion 112 of the strap 11 in one embodiment, at this time, a circuit is arranged between the optical transmitter 22 and the receiving terminal, and the circuit is arranged inside the strap 11, and one end is electrically connected to the receiving terminal, and the other end is electrically connected to the optical transmitter 22 in the mounting groove 111. The circuit is arranged inside the strap 11, so that the strap 11 protects the circuit, improves the reliability and safety of the circuit, and also improves the overall waterproof effect of the wearable device 1.

[0080] When the wearing opening 13 is formed, the shell 122 and the two ends of the strap 11 fit tightly together, and the power supply terminal 123 and the receiving terminal are electrically connected and abutted, ensuring the efficiency and stability of power transmission. In order to ensure a reliable connection between the power supply terminal 123 and the receiving terminal, the power supply terminal 123 and the receiving terminal are made of highly conductive materials, such as gold-plated copper columns or stainless steel spring pins, to improve the conductivity and durability of the contact surface. At the same time, in order to prevent moisture and dust from entering the connection area, a waterproof sealing ring or other sealing protection measures can be added around the terminal to further enhance the durability and safety of the wearable device 1.

[0081] Combination Figure 2 As shown, in one embodiment of the present invention, the wearable device 1 also includes a first light receiver 30, the display component 121 has a display surface 12a exposed in the shell 122, and a light-transmitting area 12b is formed at the edge of the display surface 12a. The first light receiver 30 is arranged in the accommodating cavity 125 and is used to receive ambient light passing through the light-transmitting area 12b.

[0082] In this embodiment, when the user wears the device, the display surface 12a faces the outside world, and the light-transmitting area 12b on the display surface 12a enables ambient light to smoothly enter the accommodating cavity 125 and be captured by the first light receiver 30. The first light receiver 30 can be a component such as a photodiode, a phototransistor or a photoresistor. The first light receiver 30 converts the received ambient light into an electrical signal and transmits it to the processing unit 23 for processing. The processing unit 23 automatically adjusts the brightness of the display screen according to the received ambient light intensity information. For example, in a bright outdoor environment, the screen brightness will be increased accordingly to ensure clear visibility; while in a darker indoor or night environment, the screen brightness will be reduced to reduce stimulation to the eyes and save power. This adaptive brightness adjustment function improves the user's visual experience.

[0083] In addition, the display surface 12a includes a display area and a non-display area, and the light-transmitting area 12b is located in the non-display area to avoid affecting the screen display in the display area. At the same time, the light-transmitting area 12b is set to be black and semi-transparent, or the same color as the shell 122 in the non-display area to improve the aesthetics of the wearable device 1. The light-transmitting area 12b is a light-transmitting material such as transparent plastic (acrylic, etc.) or glass.

[0084] Combination Figures 1 to 4As shown, in one embodiment of the present invention, the wearable device 1 further includes a first light-emitting member 40 and a communication connector 50, the first light-emitting member 40 is disposed in the housing 122, the light-emitting side of the first light-emitting member 40 is disposed toward the light-transmitting area 12b, the communication connector 50 includes a connecting portion 54, and a second light receiver 52 and a second light-emitting member 51 disposed on the connecting portion 54, the connecting portion 54 is detachably connected to the housing 122, and the second light receiver 52 and the second light-emitting member 51 are communicatively connected to an external mobile terminal;

[0085] The second light receiver 52 receives the light signal emitted by the first light emitting element 40 , and the first light receiver 30 receives the light signal emitted by the second light emitting element 51 .

[0086] In this embodiment, the communication connector 50 is provided with a second light receiver 52 and a second light emitting member 51 for realizing bidirectional optical communication. The second light receiver 52 may be a photodiode or a photoelectric coupler; the first light emitting member 40 and the second light emitting member 51 may be light emitting members such as LED or OLED; the connecting portion 54 may be a shell arranged outside the second light receiver 52 and the second light emitting member 51, or may be a plastic shell sealed outside the second light receiver 52 and the second light emitting member 51. Specifically, when the connecting portion 54 is connected to the housing 122, the optical signal emitted by the first light emitting member 40 may be transmitted to the second light receiver 52 in the communication connector 50 through the light transmission area 12b. At the same time, the optical signal emitted by the second light emitting member 51 may also be transmitted to the first light receiver 30 in the housing 122 through the light transmission area 12b. This bidirectional optical communication mechanism ensures that data can be efficiently transmitted between the wearable device 1 and the communication connector 50. In this way, the wearable device 1 can establish a stable communication connection with the mobile terminal, thereby realizing various remote management and control functions, and facilitating program upgrades and other operations. The mobile terminal may be an electronic product such as a mobile phone or a tablet.

[0087] In the traditional design, the wearable device 1 is connected to the mobile terminal through wireless communication (such as Bluetooth, Wi-Fi), which is convenient but may have delay or instability problems, especially in complex electromagnetic environments. However, this embodiment uses optical communication and optical signals as the transmission medium to avoid the influence of electromagnetic interference and ensure the real-time and reliability of data transmission.

[0088] In addition, the first light receiver 30 in this embodiment is used to receive ambient light and control the brightness adjustment of the display screen; it also serves as an optical communication medium for data transmission between the wearable device 1 and the mobile terminal, thereby improving the integration level of the wearable device 1 and reducing the processing cost.

[0089] Combination Figure 3 and Figure 4As shown, in one embodiment of the present invention, the connecting portion 54 is magnetically connected to the housing 122 .

[0090] In this embodiment, magnetic parts 53, such as permanent magnets or electromagnets, are provided inside the shell 122 and in the connecting part 54. When the user brings the connecting part 54 close to the shell 122, the magnetic force will automatically guide the two to align and fit tightly, ensuring that the second light receiver 52 and the first light emitting part 40, as well as the first light receiver 30 and the second light emitting part 51 can be accurately docked. This magnetic connection mechanism not only simplifies the user's operation process, but also improves the reliability and stability of the connection. Through this magnetic connection method, the wearable device 1 can quickly establish a stable communication connection with the mobile terminal, thereby realizing various remote management and control functions, and facilitating program upgrades and other operations.

[0091] In this embodiment, by setting a magnetic connection between the connection part 54 and the housing 122, the user only needs to bring the connection part 54 close to the housing 122 to automatically complete the connection without precise alignment or applying additional force. This not only simplifies the operation steps, but also reduces possible human errors, improving the convenience and reliability of use. In addition, the magnetic connection can maintain the surface flatness of the housing 122 and the communication connector 50, effectively preventing dust and moisture from entering the connection area, and enhancing the durability and safety of the device.

[0093] In this embodiment, the strap 11 is used to be installed on the main body 12, and together with the main body 12, it forms a wearable device 1; the strap 11 is a structure such as a watch strap or a bracelet, and its material can be metal, leather, rubber or fabric. The main body 12 is a dial, and the strap 11 and the main body 12 are detachably connected. By replacing the strap 11 with different colors, materials or specifications, the different usage needs of users can be met. The strap 11 can be provided with only a light emitter 22, or only a light sensor 21, or both a light emitter 22 and a light sensor 21. When the light emitter 22 and the light sensor 21 are provided on the strap 11 at the same time, the two are arranged at intervals along the extension direction of the strap 11. When the strap 11 is connected to the main body 12 and enclosed to form a wearing opening 13, the light emitter 22 and the light sensor 21 are both facing the wearing opening 13, and the light emitting side of the light emitter 22 faces the light receiving side of the light sensor 21. Terminals electrically connected to the main body 12 are provided at both ends of the strap 11. When the strap 11 is connected to the main body 12, the light emitter 22 and / or the light sensor 21 are electrically connected to the main body 12 through the terminals to achieve the function of health detection.

[0094] The present invention also proposes a wearable host, which includes a main body 12 and a detection component 20; the detection component 20 is arranged on the main body 12, and the detection component 20 includes a light emitter 22 and / or a light sensor 21. When the main body 12 is connected to the strap 11, the light emitting side of the light emitter 22 faces the light receiving side of the light sensor 21.

[0095] In this embodiment, the main body 12 is used to connect to the strap 11, and together with the strap 11, it forms a wearable device 1; the main body 12 is a dial or a structure that integrates circuit, data processing, display and other functions. The main body 12 and the strap 11 are detachably connected, so that the user can replace different main bodies 12. In the present application, the light emitter 22 and / or the light sensor 21 are arranged on the main body 12, and the light emitter 22 and / or the light sensor 21 are electrically connected to the power supply circuit and the processing unit arranged inside the main body 12, thereby improving the convenience of user use. It can be understood that when the light emitter 22 and the light sensor 21 are both arranged on the main body 12, in order to ensure that the light-emitting side of the light emitter 22 faces the light-receiving side of the light sensor 21, the side of the main body 12 facing the wearing channel 13 can be arranged to be a curved surface or at least partially a curved surface.
