Description

Technical Field

[0001] This application belongs to the field of wearable device technology, and specifically relates to a wearable device. Background Technology

[0002] With the continuous development of smart devices, smart rings have gradually become a focus of attention. These compact devices can be conveniently worn on the finger to collect users' physiological data in real time, such as heart rate, blood pressure, and blood oxygen saturation, thereby meeting users' needs for real-time monitoring of their physical condition.

[0003] In related technologies, a storage slot is provided on the side of the watch that contacts the user's skin, allowing the user to place a removed ring inside for convenient storage. However, when the ring is stored in the slot, the collection of the user's physiological data cannot continue, resulting in a poor user experience. Summary of the Invention

[0004] This application aims to provide a wearable device to solve the problem that existing smart rings cannot continue to collect users' physiological data when stored inside a watch, resulting in a poor user experience.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, this application discloses a wearable device, including: a watch and a ring;

[0007] The watch includes a watch body, and the side of the watch body that is in contact with the user's skin is provided with a receiving groove;

[0008] The ring is detachably housed in the receiving groove. The ring includes an inner wall near the center of the ring, and a physiological index sensor is provided on the inner wall. The physiological index sensor is used to emit and receive light to achieve detection.

[0009] The watch body is also provided with a light guide structure. When the ring is housed in the receiving groove, the light guide structure is positioned opposite the physiological indicator sensor to achieve light transmission.

[0010] In this embodiment, the watch body features a recessed compartment, allowing for convenient storage of the ring by placing it inside. This facilitates the user's use or storage of the ring anytime, anywhere. More importantly, the watch body also incorporates a light-guiding structure. With the ring stored in the compartment, the light-guiding structure is positioned opposite the physiological sensor, enabling light transmission. This means that even when the ring is removed and stored in the compartment, the physiological sensor on the ring continues to collect the user's physiological data, enhancing the user experience. Furthermore, the need for an additional physiological sensor within the watch can be eliminated, allowing it to be shared with the ring, thus saving on wearable device costs.

[0027] This application provides a wearable device, which will be described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1 This diagram illustrates the structure of the watch body of the wearable device provided in this embodiment of the application. Figures 2 to 4 The diagram shows a structural schematic of a ring for a wearable device provided in an embodiment of this application. (Refer to...) Figures 5 to 7 The diagram shows three light guide structures for wearable devices provided in embodiments of this application. (Refer to...) Figure 8 This diagram illustrates the working principle of a ring housed in a watch, as provided in an embodiment of this application; see reference. Figure 9 The diagram illustrates the working principle of the ring provided in this application when it is not housed within a watch. It should be noted that the dashed lines with arrows in the diagram represent the light transmission path, and the dashed lines also represent the user's skin A.

[0029] like Figures 1 to 2 As shown, this application provides a wearable device, including: a watch and a ring 2; the watch includes a watch body 1, and the side of the watch body 1 that is in contact with the user's skin A is provided with a receiving groove; the ring 2 is detachably housed in the receiving groove, and the ring 2 includes an inner wall 211 near the center of the ring 2, and a physiological indicator sensor is provided in the inner wall 211, which is used to emit and receive light to achieve detection; wherein, a light guide structure 3 is also provided in the watch body 1, and when the ring 2 is housed in the receiving groove, the light guide structure 3 is positioned opposite to the physiological indicator sensor to achieve light transmission.

[0030] In this embodiment, the watch body 1 has a receiving slot, allowing for convenient storage of the ring 2 by placing it inside, making it easy for users to use or store the ring 2 anytime, anywhere. More importantly, the watch body also features a light-guiding structure 3, and with the ring 2 stored in the receiving slot, the light-guiding structure 3 is positioned opposite the physiological indicator sensor, enabling light transmission. This means that even when the ring 2 is removed and stored in the receiving slot, the physiological indicator sensor on the ring 2 can continue to collect the user's physiological data, improving the user experience. Furthermore, the need for an additional physiological indicator sensor within the watch can be eliminated, allowing it to be shared with the ring 2, thus saving on the cost of wearable devices.

[0031] It should be noted that the physiological indicator sensors in this application embodiment include, but are not limited to, photoplethysmography (PPG) sensors, bioelectrical impedance sensors, electrocardiography (ECG) sensors, and electromyography (EMG) sensors, etc., and are not limited thereto. Those skilled in the art can adjust them according to actual needs. Taking the PPG sensor as an example, the PPG sensor is a sensor used to measure heart rate. Specifically, the PPG sensor includes a light-emitting unit 22 (such as a light-emitting diode (LED)) and a light-receiving unit 23 (such as a photodetector (PD)). The LED emits light to reach the tissues, veins, and arteries in the user's skin A, and the light is absorbed and reflected back to the photodetector. Under the premise that there is no large movement at the measurement site, the absorption of light by muscles, bones, veins, and other connecting tissues is basically unchanged. However, blood is different. Because there is blood flow in the arteries, the absorption of light naturally changes. When light is converted into an electrical signal, the absorption of light by arteries changes while the absorption of light by other tissues remains basically unchanged. The resulting signal can be divided into direct current (DC) signal and alternating current (AC) signal. By extracting the AC signal, the characteristics of blood flow can be reflected, thereby obtaining the user's heart rate parameters in real time.

[0032] In some optional embodiments of this application, a boss 12 protruding towards the opening of the receiving groove is provided in the receiving groove, and the boss 12 and at least part of the receiving groove enclose an annular cavity 11; a light guide structure 3 is disposed within the boss 12; the ring 2 is detachably received in the annular cavity 11, and the inner wall 211 corresponds to the boss 12 so that the physiological index sensor is opposite to the light guide structure 3. In this way, when the ring 2 is received in the annular cavity 11, the physiological index sensor disposed on the inner wall 211 can be opposite to the light guide structure 3 disposed in the boss 12, thereby realizing the transmission of light, so that the ring 2 stored in the annular cavity 11 can continuously collect the user's physiological data, which is beneficial to improving the user experience. In addition, by setting an annular cavity 11 that is adapted to the shape of the ring 2, the space required to store the ring 2 can be reduced, which is beneficial to the miniaturization design of wearable devices.

[0033] In some optional embodiments of this application, the physiological indicator sensor includes: a light-emitting unit 22 and a light-receiving unit 23 spaced apart; a light-guiding structure 3 at least covers the light-emitting unit 22 and the light-receiving unit 23, the light-guiding structure 3 being used to conduct the light emitted by the light-emitting unit 22 and the light received by the light-receiving unit 23. Figures 5 to 7 In this context, user skin A refers to the local skin corresponding to the wearable device 1 when the user wears the device. It can be understood that the location detected by the physiological indicator sensor is not fixed, but changes with the user's wearing position.

[0034] In this embodiment, since the light guide structure 3 at least covers the light-emitting unit 22 and the light-receiving unit 23, the light guide structure 3 can conduct the light emitted by the light-emitting unit 22 to the user's skin A as much as possible, and enable the receiving unit to receive the light reflected from the user's skin A as much as possible. This improves the reliability of physiological indicator sensor data acquisition.

[0035] It should be noted that, as Figures 3 to 4 As shown, the light-emitting unit 22 and the light-receiving unit 23 can be spaced apart along the axial direction of the ring 2 or spaced apart along the circumferential direction of the ring 2. No limitation is made here, and those skilled in the art can adjust them according to actual needs.

[0036] This application provides three light guide structures 3, which are described below in conjunction with the appendix. Figures 5 to 7 The three light guide structures are described in detail.

[0037] In one embodiment, such as Figure 5As shown, the boss 12 includes a first bottom wall 121, which is used to contact the user's skin A; the light guide structure 3 is a prism 31, which includes a first light-receiving surface 311 and a second light-receiving surface 312 arranged at an angle, the first light-receiving surface 311 facing the light-emitting unit 22 and the light-receiving unit 23, and the second light-receiving surface 312 facing the first bottom wall 121.

[0038] In this embodiment, a prism 31 is provided, with its first light-receiving surface 311 facing the light-emitting unit 22 and the light-receiving unit 23, and its second light-receiving surface 312 facing the first bottom wall 121. Thus, when the wearable device is worn on a user's limb, the first bottom wall 121 contacts the user's skin A. The light emitted by the light-emitting unit 22 is sequentially transmitted to the user's skin A via the first light-receiving surface 311 and the second light-receiving surface 312. The light reflected from the user's skin A is sequentially transmitted to the light-receiving unit 23 via the second light-receiving surface 312 and the first light-receiving surface 311, thereby achieving continuous collection of physiological data.

[0039] It should be noted that the embodiments of this application do not limit the type of prism 31 or the specific value of the angle between the first light-receiving surface 311 and the second light-receiving surface 312. Those skilled in the art can adjust it according to actual needs. For example, the angle between the first light-receiving surface 311 and the second light-receiving surface 312 can be 60°, 45°, 30° or other values. In one embodiment, the light-emitting unit 22 and the light-receiving unit 23 are arranged at intervals along the axial direction of the ring 2. The prism 31 is a right-angle prism 31, which includes two mutually perpendicular first surfaces and an inclined second surface. The first light-receiving surface 311 is one of the two first surfaces, and the second light-receiving surface 312 is the second surface. The angle between the first light-receiving surface 311 and the second light-receiving surface 312 is 45°, and the first light-receiving surface 311 is arranged parallel to the axial direction of the ring 2.

[0040] In another embodiment, such as Figure 6 As shown, the light guide structure 3 includes a first reflector 32 and a second reflector 33 spaced apart. The first reflector 32 is positioned opposite to the light-emitting unit 22 and is used to conduct the light emitted by the light-emitting unit 22. The second reflector 33 is positioned opposite to the light-receiving unit 23 and is used to conduct the light received by the light-receiving unit 23.

[0041] In this embodiment, by setting a first reflector 32 opposite to the position of the light-emitting unit 22, the light emitted by the light-emitting unit 22 can be transmitted to the user's skin A. By setting a second reflector 33 opposite to the position of the light-receiving unit 23, the light reflected by the user's skin A can be transmitted to the light-receiving unit 23, thereby realizing the continuous collection of physiological data.

[0042] Taking the arrangement of the light-emitting unit 22 and the light-receiving unit 23 along the axial direction of the ring 2 as an example, those skilled in the art can adjust the distance between the light-emitting unit 22 and the first reflector 32, and the distance between the light-receiving unit 23 and the second reflector 33, to avoid the problem of light emitting from the light-emitting unit 22 and light receiving from the light-receiving unit 23 intersecting. However, this may result in an excessively large distance between the first reflector 32 and the second reflector 33. When the first reflector 32 and the second reflector 33 are arranged in parallel, the second reflector 33 may receive insufficient light and transmit it to the light-receiving unit 23, thereby affecting the reliability of data acquisition. Based on this, in some optional embodiments of this application, the first reflector 32 has a first center line, the second reflector 33 has a second center line, and the second center line intersects with the first center line.

[0043] In this embodiment, since the first center line of the first reflector 32 intersects the second center line of the second reflector 33, that is, with respect to the first bottom wall 121, the tilt angles of the first reflector 32 and the second reflector 33 are different. Thus, with one reflector's tilt angle remaining constant, the amount of light received and transmitted to the light-collecting unit 23 by the second reflector 33 can be increased by adjusting the tilt angle of the other reflector, which is beneficial for improving the reliability of physiological indicator sensor data acquisition.

[0044] It should be noted that the embodiments of this application do not limit the tilt angle of the first reflector 32 and the second reflector 33 relative to the first bottom wall 121, and those skilled in the art can adjust them according to actual needs. For example, while ensuring that the tilt angles of the first reflector 32 and the second reflector 33 are different, the tilt angles of the first reflector 32 and the second reflector 33 can be 60°, 45°, 30° or other values.

[0045] In yet another embodiment, such as Figure 7 As shown, the boss 12 includes a first bottom wall 121 for contacting the user's skin A; the light guide structure 3 includes a first optical fiber 34 and a second optical fiber 35, one end of the first optical fiber 34 is opposite to the light-emitting unit 22, and the other end of the first optical fiber 34 extends to the first bottom wall 121, and the first optical fiber 34 is used to conduct the light emitted by the light-emitting unit 22; one end of the second optical fiber 35 is opposite to the light-receiving unit 23, and the other end of the second optical fiber 35 extends to the first bottom wall 121, and the second optical fiber 35 is used to conduct the light received by the light-receiving unit 23.

[0046] In this embodiment, a first optical fiber 34 and a second optical fiber 35 are provided. One end of the first optical fiber 34 is opposite to the light-emitting unit 22, and the other end extends to the first bottom wall 121. Similarly, one end of the second optical fiber 35 is opposite to the light-receiving unit 23, and the other end extends to the first bottom wall 121. Thus, when the wearable device is worn on a user's limb, the first bottom wall 121 contacts the user's skin A. The light emitted by the light-emitting unit 22 can be conducted to the user's skin A via the first optical fiber 34, and the light reflected from the user's skin A can be conducted to the light-receiving unit 23 via the second optical fiber 35, thereby achieving continuous collection of physiological data.

[0047] In some optional embodiments of this application, the boss 12 includes a first bottom wall 121 and a first peripheral wall 122 extending circumferentially along the first bottom wall 121. The first bottom wall 121 is used to contact the user's skin A. The boss 12 is also provided with a light channel 4, which has two opposite ends. One end of the light channel 4 extends to the first bottom wall 121, and the other end of the light channel 4 extends to the first peripheral wall 122 and is opposite to the physiological index sensor. At least a portion of the light guide structure 3 is disposed in the light channel 4.

[0048] In this embodiment, a light channel 4 is provided, with one end extending to the first bottom wall 121 and the other end extending to the first peripheral wall 122 and opposite to the physiological indicator sensor. This reduces optical interference and improves light transmission efficiency during light transmission, thereby enhancing the monitoring reliability of the physiological indicator sensor. Furthermore, since at least a portion of the light guide structure 3 is disposed within the light channel 4, the light transmission path can be altered, allowing the light to travel along a predetermined path between the physiological indicator sensor and the user's skin A.

[0049] It should be noted that, when the light guide structure 3 is a prism 31, "at least a portion of the light guide structure 3 is disposed in the light channel 4" means that the light channel 4 includes a first light channel 4 and a second light channel 4 spaced apart, and the prism 31 is disposed between the first light channel 4 and the second light channel 4. When the light guide structure 3 consists of two mirrors, "at least a portion of the light guide structure 3 is disposed in the light channel 4" means that the mirror is disposed at a bend in the light channel 4 and is connected to the light channel 4. When the light guide structure 3 consists of two optical fibers, "at least a portion of the light guide structure 3 is disposed in the light channel 4" means that the optical fibers are embedded within the light channel 4.

[0050] In some optional embodiments of this application, the physiological indicator sensor includes a light-emitting unit 22 and a light-receiving unit 23 arranged at intervals; the light channel 4 includes an independent light-emitting channel and a light-receiving channel, with the light-emitting channel corresponding to the light-emitting unit 22 and the light-receiving channel corresponding to the light-receiving unit 23.

[0051] In this embodiment, by setting independent light-emitting channels and light-receiving channels, the light emitted by the light-emitting unit 22 and the light received by the light-receiving unit 23 in the protrusion 12 can be made to not interfere with each other, which is beneficial to improving the measurement reliability of the physiological index sensor.

[0052] In some optional embodiments of this application, the ring 2 is further provided with a first electrical connector 24; the watch body 1 is further provided with a second electrical connector. When the ring 2 is received in the receiving groove, the second electrical connector is positioned opposite to the first electrical connector 24 and is electrically connected to the first electrical connector 24. Specifically, the first electrical connector 24 is provided on the body 21 of the ring 2; the second electrical connector may be provided on the boss 12 and / or the annular cavity 11.

[0053] In this embodiment, since the ring 2 is provided with a first electrical connector 24 and the watch body 1 is provided with a second electrical connector, the electrical connection between the first electrical connector 24 and the second electrical connector can realize the transmission of electrical energy and / or data between the ring 2 and the watch.

[0054] It should be noted that the embodiments of this application do not limit the placement of the first electrical connector 24 and the second electrical connector, and those skilled in the art can adjust them according to actual needs. Specifically, the ring 2 includes a body 21, which includes an inner wall 211, an outer wall 212, and a side wall 213 located between the inner wall 211 and the outer wall 212, which are spaced apart from the inside to the outside. The inner wall 211 is located close to the center of the body 21. The annular cavity 11 includes a second bottom wall 111 and a second peripheral wall 112 extending circumferentially along the second bottom wall 111. In one embodiment, the first electrical connector 24 is disposed on the inner wall 211 of the body 21, and correspondingly, the second electrical connector is disposed on the first peripheral wall 122 of the boss 12. In another embodiment, the first electrical connector 24 is disposed on the outer wall 212 of the body 21, and correspondingly, the second electrical connector is disposed on the second peripheral wall 112 of the annular cavity 11. In another embodiment, the first electrical connector 24 is disposed on the side wall 213 of the body 21, and correspondingly, the second electrical connector is disposed on the second bottom wall 111 of the annular cavity 11. The embodiments of this application do not limit the placement of the first electrical connector 24 and the second electrical connector; those skilled in the art can adjust them according to actual needs.

[0055] Furthermore, the embodiments of this application do not limit the types of the first electrical connector 24 and the second electrical connector, and those skilled in the art can design them according to actual needs. In one embodiment, the first electrical connector 24 and the second electrical connector are two mutually matched power transmission interfaces. Through the electrical connection between the first electrical connector 24 and the second electrical connector, the ring 2 can be charged. In another embodiment, the first electrical connector 24 and the second electrical connector are two mutually matched data transmission interfaces. Through the electrical connection between the first electrical connector 24 and the second electrical connector, the ring 2 can transmit data with the watch. In yet another embodiment, the first electrical connector 24 includes a power transmission interface and a data transmission interface. Correspondingly, the second electrical connector includes a power transmission interface and a data transmission interface that match the first electrical connector. Through the electrical connection between the first electrical connector 24 and the second electrical connector, that is, the electrical connection of the two power transmission interfaces and the electrical connection of the two data transmission interfaces, not only can the ring 2 be charged, but also the ring 2 can transmit data with the watch. In addition, as Figures 3 to 4 As shown, when both power transmission interface and data transmission interface are provided, each interface can be distributed sequentially at intervals along the extension direction of the inner wall 211, or it can be arrayed on the inner wall 211. This application embodiment does not limit the arrangement of each interface, and those skilled in the art can make adjustments according to actual needs.

[0056] Furthermore, data transmission between the ring 2 and the watch in this embodiment can also be achieved via wireless data transmission. Specifically, the ring 2 and the watch are each equipped with two matched wireless communication modules, and data transmission can be achieved through the interconnection of these wireless communication modules. The following description, in conjunction with... Figures 8 to 9 The working principle of the wearable device according to the embodiments of this application will be described. Figure 8 As shown, when ring 2 is housed within the watch (i.e., when the user is only wearing the watch), the watch's power management module outputs electrical energy, which is transmitted sequentially through the watch's power transmission interface and then through ring 2's power transmission interface to ring 2's power management module, thereby powering the power-requiring components of ring 2, such as the central processing unit (CPU). Simultaneously, data collected by the PPG sensor in ring 2 is processed by ring 2's CPU and then transmitted sequentially through ring 2's data transmission interface and then through the watch's data transmission interface to the watch's CPU, thus achieving data transmission. Figure 9 As shown, when ring 2 is not housed within the watch (i.e., when the user wears both ring 2 and the watch simultaneously), the data collected by the PPG sensor in ring 2 is processed by the central processing unit of ring 2, and then transmitted sequentially through the wireless communication module of ring 2 and the wireless communication module of the watch to the central processing unit of the watch, thus achieving data transmission. In this case, the watch can also be replaced with other electronic devices, such as a mobile phone.

[0057] In some optional embodiments of this application, the ring 2 is further provided with a first suction member (not shown in the drawings); the watch body 1 is further provided with a second suction member (not shown in the drawings). When the ring 2 is received in the receiving groove, the second suction member is positioned opposite to the first suction member and attracts the first suction member to limit the ring 2. Specifically, the first suction member is provided on the body 21 of the ring 2; the second suction member may be provided on the boss 12 and / or the annular cavity 11.

[0058] In this embodiment of the application, since the ring 2 is provided with a first suction member, and the boss 12 and / or the annular cavity 11 is provided with a second suction member, the ring 2 can be limited by the mutual attraction of the first suction member and the second suction member, so that the ring 2 can be reliably housed in the annular cavity 11.

[0059] It should be noted that the types of the first and second attracting components are not limited in the embodiments of this application. In one embodiment, the first and second attracting components are two magnetic components that attract each other, and the ring 2 is positioned by the mutual attraction of the two magnetic components. In another embodiment, one of the first and second attracting components is a magnetic component, and the other is a metal component, and the ring 2 is positioned by the magnetic component attracting the metal component.

[0060] Furthermore, the embodiments of this application do not limit the placement of the first and second suction members, and those skilled in the art can adjust them according to actual needs. Specifically, in one embodiment, the first suction member is disposed on the inner wall 211 of the body 21, and correspondingly, the second suction member is disposed on the first peripheral wall 122 of the boss 12. In another embodiment, the first suction member is disposed on the outer wall 212 of the body 21, and correspondingly, the second suction member is disposed on the second peripheral wall 112 of the annular cavity 11. In yet another embodiment, the first suction member is disposed on the side wall 213 of the body 21, and correspondingly, the second suction member is disposed on the second bottom wall 111 of the annular cavity 11. The embodiments of this application do not limit the placement of the first and second suction members, and those skilled in the art can adjust them according to actual needs while avoiding other components. Furthermore, the embodiments of this application do not limit the number of the first and second suction members, and those skilled in the art can adjust them according to actual needs. It is understood that the number of the first and second suction members should be the same and their positions should be identical.

[0061] In some optional embodiments of this application, the ring 2 is further provided with one of a positioning protrusion 25 or a positioning recess 13; the receiving groove is provided with the other of a positioning protrusion 25 or a positioning recess 13; when the ring 2 is received in the receiving groove, the positioning protrusion 25 is embedded in the positioning recess 13. Specifically, the positioning protrusion 25 or the positioning recess 13 is provided on the body 21 of the ring 2, and the positioning protrusion 25 or the positioning recess 13 can be provided in the boss 12 and / or the annular cavity 11.

[0064] In summary, the wearable device provided in this application has at least the following advantages:

[0065] In this embodiment, the watch body features a recessed compartment, allowing for convenient storage of the ring by placing it inside. This facilitates the user's use or storage of the ring anytime, anywhere. More importantly, the watch body also incorporates a light-guiding structure. With the ring stored in the compartment, the light-guiding structure is positioned opposite the physiological sensor, enabling light transmission. This means that even when the ring is removed and stored in the compartment, the physiological sensor on the ring continues to collect the user's physiological data, enhancing the user experience. Furthermore, the need for an additional physiological sensor within the watch can be eliminated, allowing it to be shared with the ring, thus saving on wearable device costs.
