Wherein the sensor array comprises one or more sensors, the sensors are used for collecting physiological signals, the sensor array is arranged on the first surface layer, and the first magnet array and the second magnet array are located in an interlayer formed by the first surface layer and the second surface layer. The first magnet array is located on the first surface layer, the second magnet array is located on the second surface layer, and the first magnet array drives the first surface layer to be close to or away from the second surface layer under the action of a magnetic field between the first magnet array and the second magnet array.

Description

Technical Field

[0001] This application relates to the field of smart wearables, and more particularly to a sensor module, a watchband, and related devices. Background Technology

[0002] Currently, wearable devices can use sensors to measure users' physiological parameters, such as blood pressure, blood sugar, heart rate, etc., allowing users to understand their physical condition anytime, anywhere.

[0003] When wearable devices detect physiological parameters, sensors typically need to be in contact with the user's skin to obtain accurate measurements. Taking a watch-shaped wearable device as an example, the sensors are mostly placed at the bottom of the watch face. The device measures the user's physiological parameters by collecting signals from the outer side of the wrist. However, the skin temperature and capillary perfusion on the outer side of the wrist are easily affected by ambient temperature, leading to poor signal quality and high noise levels in the collected physiological signals. Placing the sensor on the inner side of the wrist can mitigate this problem to some extent; however, due to individual physiological differences and high wrist mobility, the sensor's contact with the skin is often poor, and the wearable device still cannot collect stable and high-quality physiological signals. Summary of the Invention

[0004] This application provides a sensor module, a watchband, and related devices that solve the problem of poor adhesion between the sensor and human skin.

[0005] In a first aspect, embodiments of this application provide a sensor module, which may include: a sensor array, a first surface layer, a first magnet array, a second magnet array, and a second surface layer; wherein, the sensor array includes one or more sensors for collecting physiological signals, the sensor array is disposed on the first surface layer, the first magnet array and the second magnet array are located in the sandwich formed by the first surface layer and the second surface layer, the second magnet array is located on the second surface layer, and under the action of the magnetic field between the first magnet array and the second magnet array, the first magnet array drives the first surface layer to move closer to or away from the second surface layer.

[0006] As can be seen, the embodiments of this application provide a novel sensor module. When the sensor module is attached to human skin to collect physiological signals, the first surface layer can drive the sensor array to move closer to or further away from human skin, thereby solving the problem of poor adhesion between the sensor and human skin.

[0007] In conjunction with the first aspect, in one possible implementation, the first surface layer is a flexible surface layer and the second surface layer is a rigid backing layer.

[0008] The first surface layer is a flexible surface layer, and the second surface layer is a rigid backing layer. Under the influence of a magnetic field, the first surface layer is more likely to deform due to the force, while the second surface layer is less likely to deform due to the force. This allows the first surface layer to move away from or closer to the second surface layer due to the force, thereby causing the sensor module to move closer to or away from the human skin.

[0009] In conjunction with the first aspect, in one possible implementation, the sensor array may include a first sensor disposed on a side of a first surface layer facing away from the second surface layer, and the first surface layer is located between the first magnet array and the first sensor.

[0010] As can be seen, the sensor array may include a sensor that can directly contact or face the skin, namely the first sensor, which the watch band can use to collect the user's physiological signals.

[0011] In conjunction with the first aspect, in one possible implementation, the sensor array may include a second sensor disposed on the side of the first surface layer facing the second surface layer, and the second sensor is located between the first magnet array and the first surface layer.

[0012] As can be seen, the sensor array may include sensors that cannot directly contact or face the skin, i.e., second sensors, which the watch band can use to collect the user's physiological signals.

[0013] In conjunction with the first aspect, in one possible implementation, the magnets included in the first magnet array are permanent magnets, and the magnets included in the second magnet array are electromagnets.

[0014] In this configuration, one or more magnets in the first magnet array can correspond one-to-one with one or more magnets in the second magnet array.

[0015] Understandably, the first magnet array can contain magnets that are all electromagnets, all permanent magnets, or both. Similarly, the second magnet array can contain magnets that are all electromagnets, all permanent magnets, or both.

[0016] In conjunction with the first aspect, in one possible implementation, both the first magnet array and the second magnet array contain multiple magnets arranged in a first arrangement.

[0017] In other words, the magnets in the first and second magnet arrays are arranged in the same way, which can ensure that there is a strong magnetic force between the two magnet arrays as much as possible.

[0018] In conjunction with the first aspect, in one possible implementation, the first arrangement includes the Nth row and the N+1th row, with the magnets in the Nth row and the magnets in the N+1th row interspersed, where N is an integer greater than or equal to 1.

[0019] In conjunction with the first aspect, in one possible implementation, the first arrangement is that the first and third rows each have three magnets, the second row has two magnets, and the magnets in the second row are placed in a gap relative to the magnets in the first and third rows.

[0020] In this case, the arrangement of both the first and second magnet arrays can be "3+2+3".

[0021] In conjunction with the first aspect, in one possible implementation, the sensor array includes a third sensor for acquiring a second signal; one or more sensors in the sensor array are used to acquire a first signal when the second signal satisfies a first condition.

[0022] The third sensor and the first sensor can be the same sensor, or the third sensor and the second sensor can be the same sensor, or the first sensor, the second sensor and the third sensor can be different sensors.

[0023] As can be seen, the watchband can determine the degree of contact between the sensor array and human skin based on the signal collected by the third sensor, thereby enabling the watchband to collect stable and high-quality physiological signals under a specified degree of contact.

[0024] In conjunction with the first aspect, in one possible implementation, the third sensor is a pressure sensor, the second signal is used to reflect the pressure detected by the third sensor, and the first condition is that the pressure detected by the third sensor is within a preset range.

[0025] In other words, the watch band can determine the degree of contact between the sensor array and human skin based on the pressure detected by the pressure sensor. When the pressure detected by the pressure sensor is within a preset range, one or more sensors in the sensor array can collect stable physiological signals with high signal quality.

[0026] In conjunction with the first aspect, in one possible implementation, the first condition can be that the signal quality of the first signal is greater than a threshold. In this case, the third sensor can be any one or more sensors in a sensor array.

[0027] In other words, the watch band can determine the degree of fit between the sensor array and human skin based on the signal quality of the signal collected by the third sensor. When the signal quality of the physiological signal collected by the third sensor is greater than the threshold, one or more sensors in the sensor array can collect a stable physiological signal with high signal quality.

[0028] Understandably, this first condition may differ depending on the sensor used to collect physiological signals.

[0029] Secondly, embodiments of this application provide a watch strap, including: a watch strap body and a sensor module located on the watch strap body, the sensor module being the sensor module described in the first aspect or any implementation thereof; wherein, the side of the second surface layer facing away from the first surface layer is disposed on the watch strap body.

[0030] The sensor module can be worn on the human body through the watch strap, so that the sensor can fit against the human skin and collect the physiological signals required to measure physiological parameters. The watch strap can be worn in a variety of ways, such as wrapping around the first part of the human body or sticking to the human skin.

[0031] In conjunction with the second aspect, in one possible implementation, the watchband further includes: a processor; a sensor module as described in the implementation of the first aspect, the processor being configured to adjust the current of the first magnet array and / or the second magnet array based on the second signal acquired by the third sensor, such that the second signal acquired by the third sensor satisfies a first condition.

[0032] In other words, the watch band can adjust the current of the first and second magnet arrays based on the physiological signals collected by the sensors, thereby adjusting the degree of contact between the sensor array and the human skin to a specified level.

[0033] In conjunction with the second aspect, in one possible implementation, the watchband further includes: a communication module; the communication module is used to transmit physiological signals acquired by the sensor array, and / or to receive instructions for acquiring physiological signals.

[0034] As can be seen, the watch strap can communicate with other devices through the communication module. These other devices can refer to any device, such as a mobile phone, tablet, etc.

[0035] In conjunction with the second aspect, in one possible implementation, the watch strap also includes a buckle for wrapping the watch strap around a first part of the body.

[0036] For example, the clasp can be a magnetic clasp, a mechanical clasp, or other types of clasp.

[0037] In conjunction with the second aspect, in one possible implementation, the watch strap also includes a stretching structure located on the main body of the watch strap, which is used to extend the length of the watch strap.

[0038] As can be seen, the length of the watch strap can be extended by stretching the structure, thus expanding the wearing scenarios of the watch strap. In addition to wearing the watch strap on the wrist, it can also be worn on the arm, waist or other parts of the body with a longer circumference.

[0039] Understandably, the watch strap may include one or more stretch structures.

[0040] Additionally, the tensioning structure can be located in an area of ​​the watchband body where no electrical connection is provided. If the watchband includes a positioning marker, the tensioning structure can be positioned outside the area between the sensor module and the positioning marker to prevent the stretching or contraction of the tensioning structure from altering the distance between the sensor module and the positioning marker, thereby affecting the user's ability to locate the target using the positioning marker.

[0041] In conjunction with the second aspect, in one possible implementation, the watchband further includes: a positioning marker, the distance between the positioning marker and the sensor module is a first distance, the first distance is within a first range, and the size of the sensor module is a first size, the first size is within a second range. When the watchband is worn on a first part of the human body, if the positioning marker is at a first position on the first part, the sensor module faces the first detection target on the first part.

[0042] As can be seen, the introduction of positioning markers can help users locate the position of the sensor module, making it convenient for users to face the sensor module toward the designated detection target on the human body when wearing the watch strap.

[0043] For example, with reference to the watch strap being worn on the human body, the positioning mark can be located on the side of the watch strap facing the human skin, or on the side of the watch strap facing away from the human skin, or both the side of the watch strap facing the human skin and the side facing away from the human skin can be provided with positioning marks.

[0044] It is understood that the positioning mark can be presented as a raised structure on the watch strap, a pattern on the watch strap, or a surface area with a different color or material from the rest of the watch strap. The embodiments of this application do not limit the shape of the positioning mark.

[0045] In conjunction with the second aspect, in one possible implementation, the watch strap further includes a connecting component for securing the watch strap to the watch head.

[0046] For example, the connecting component can fix the watch strap to other components through principles such as magnetic field action or mechanical action.

[0047] In conjunction with the second aspect, in one possible implementation, the connecting component includes a magnetic strip, which is fixed by the magnetic field interaction between the magnetic strip on the connecting component and the magnetic strip on the meter head.

[0048] It is understood that the connecting component may include one or more magnetic strips. The embodiments of this application do not limit the number, position, size, or pattern of the magnetic strips included in the connecting component.

[0049] In conjunction with the second aspect, in one possible implementation, the magnetic field range of the magnetic strip of the connecting component is greater than the magnetic field range of the magnetic strip of the meter head.

[0050] The magnetic field range of the magnetic strip of the connecting component is greater than that of the magnetic strip of the watch head. This allows the user to adjust the position of the watch head on the watch band after it is fixed to the band, enabling fine-tuning of the watch head's position. This allows the user to adjust the position of the watch head on their body according to their needs without having to adjust the band when wearing a watch band with the watch head fixed to it.

[0051] In conjunction with the second aspect, in one possible implementation, the watchband further includes: a communication module, the connecting component comprising two magnetic strip arrays, the communication module being located between the two magnetic strip arrays, the magnetic strip arrays extending along the long side of the watchband; or, the connecting component comprising a ring-shaped magnetic strip array, the communication module being located within the ring of the magnetic strip array.

[0052] By adjusting the positions of the communication module and connecting components, the distance that the signal needs to travel when the watch strap is fixed to other devices can be shortened, thus improving the communication quality between the watch strap and other devices.

[0053] In conjunction with the second aspect, in one possible implementation, the watchband further includes: a first connecting component and / or a second connecting component, wherein the first connecting component and the sensor module are located on different sides of the watchband, the first connecting component being used to fix the watchband to the patch, the patch being used to fix it to the inside of clothing; and the second connecting component and the sensor module are located on the same side of the watchband, the second connecting component being used to fix the watchband to the patch, the patch being used to fix it to human skin.

[0054] As can be seen, watch straps can be used with patches to be applied to human skin. Different connecting parts and wearing methods can be used on the watch strap to achieve the desired application to human skin, depending on the way the patches are worn.

[0055] For example, the patch can be presented in shapes such as rectangles, circles, triangles, etc.

[0056] Thirdly, embodiments of this application provide an electronic device, which includes: a watch strap and a watch head; wherein the watch head is disposed on the watch strap, and the watch strap is the watch strap described in the second aspect or any implementation thereof.

[0057] In conjunction with the third aspect, in one possible implementation, the meter head includes: a display screen for displaying physiological parameters determined based on a first signal acquired by the watch band, and / or, a first user interface including controls for triggering the acquisition of the first signal.

[0058] As can be seen, electronic devices can interact with users through the meter, display the measured physiological parameters to the user, and / or initiate the acquisition of specified physiological signals based on the user's wishes.

[0059] In conjunction with the third aspect, in one possible implementation, the watch head further includes a connecting component located on the side of the watch head facing the watch strap, and the watch head is fixed to the watch strap via the connecting component.

[0060] For example, the connecting parts on the watch head can be used to fix the watch head to the watch strap through principles such as magnetic field action or mechanical action.

[0061] In conjunction with the third aspect, in one possible implementation, the meter head also includes: a communication module, which is used to receive the first signal collected by the watch band and / or send an instruction to the watch band to collect the first signal.

[0062] As can be seen, the watch head can communicate with the watch band through the communication module.

[0063] In conjunction with the third aspect, in one possible implementation, the watch head further includes a processor for identifying sensors contained in the watch band, wherein the first signal is a physiological signal determined by the watch head based on the sensors contained in the watch band.

[0064] In conjunction with the third aspect, in one possible implementation, the meter head may also include a sensor module. While the watch band collects physiological signals through the sensor module, the meter head can also collect physiological signals through its own sensor module. Then, the meter head can use the physiological signals collected by the meter head and the physiological signals collected by the watch band to jointly determine the physiological parameters.

[0065] It is evident that if both the meter head and the watch band have the relevant functions for measuring physiological parameters, then the meter head and the watch band can work together to complete the measurement of the specified physiological parameters. Attached Figure Description

[0086] The embodiments of this application are described below with reference to the accompanying drawings. The embodiments described herein with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0087] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. It should be understood that in this application, "electrical connection" can be understood as components physically contacting and conducting electricity; it can also be understood as a form of connection between different components in a circuit structure through physical lines that can transmit electrical signals, such as copper foil or wires on a printed circuit board (PCB). "Connection" and "connected" can both refer to a mechanical connection relationship or a physical connection relationship. For example, A and B being connected or A and B being connected can mean that there are fastening components (such as screws, bolts, rivets, etc.) between A and B, or that A and B are in contact with each other and are difficult to separate.

[0088] Furthermore, the term "fixed" in this document should be interpreted broadly. For example, "fixed" can mean direct fixing or indirect fixing through an intermediate medium. "Fixed" refers to connections where the relative positional relationship remains unchanged after connection. The directional terms used in the embodiments of this application, such as "upper" and "lower," are merely for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. "Multiple" refers to two or more.

[0089] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0090] In the embodiments of this application, the mathematical concepts mentioned, such as parallel and perpendicular, are limitations specific to the current technological level, rather than absolute and strict mathematical definitions. Slight deviations are permissible; approximations of parallelism or perpendicularity are acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 10 and 100 degrees.

[0091] In the description of the embodiments in this application, unless otherwise stated, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone.

[0092] It is understood that the specific embodiments described herein are merely illustrative of the relevant application and not intended to limit the application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings.

[0093] The term "user interface (UI)" used in the following embodiments of this application refers to the medium interface through which an application or operating system interacts and exchanges information with the user. It realizes the conversion between the internal form of information and the form that the user can accept. The user interface is source code written in a specific computer language such as Java or Extensible Markup Language (XML). The interface source code is parsed and rendered on the electronic device, ultimately presenting content that the user can recognize. A common form of user interface is the graphical user interface (GUI), which refers to a user interface related to computer operation displayed graphically. It can be visible interface elements such as text, icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, and widgets displayed on the screen of an electronic device.

[0094] Figure 1 This is a schematic diagram of one embodiment of the watch strap 100 provided in this application.

[0095] It should be noted that the watch strap 100 is not intended to limit it to a watch strap. In other embodiments of this application, the watch strap may also be referred to as a wristband, cuff, strap, etc. This application embodiment does not limit the name.

[0096] The watch strap 100 can be used to collect physiological signals required for measuring physiological parameters through sensors when worn on the human body.

[0097] For example, the sensor may include any one or more of the following: a photoelectric sensor, an ultrasonic sensor, a pressure sensor, etc. For instance, a photoelectric sensor can be used to acquire photoplethysmography (PPG) signals, and a pressure sensor can be used to acquire pressure signals, etc.

[0098] For example, physiological parameters may include, but are not limited to, one or more of the following: blood pressure, blood glucose, blood oxygen, heart rate, respiratory rate, etc.

[0099] The watch strap 100 provided in this application embodiment can be worn in one or more of the following ways:

[0100] 1) The watch strap 100 can wrap around the first part of the body.

[0101] The first part can refer to the wrist, ankle, arm, waist, etc.

[0102] When the first part is the wrist, this is the way to wear a watch.

[0103] Furthermore, the watch band 100 can also be fixed to the watch head 200. For example, the watch band 100 can send the collected physiological signals to the watch head 200. Further, the watch band 100 can send the collected physiological signals to the watch head 200 based on a command from the watch head 200 to measure physiological parameters. In other words, the user can measure physiological parameters by interacting with the watch head 200. For example, the watch head 200 can detect when the user initiates a physiological parameter measurement operation, send a command to the watch band 100 to measure the physiological parameters, and the watch band 100 can initiate the measurement of physiological parameters based on this command. The watch head 200 can also receive the physiological signals collected by the watch band 100 and display the physiological parameters measured based on these signals.

[0104] For a detailed description of header 200, please refer to the following content, which will not be elaborated here.

[0105] 2) The watch strap 100 can be applied to human skin.

[0106] In one possible implementation, the watch strap 100 can be attached to human skin using a patch 300. One side of the patch 300 can be fixed to the watch strap 100, while the other side can be adhered to clothing or human skin. In this way, by using the patch 300, the watch strap 100 can come into contact with human skin, enabling the collection of physiological signals transmitted by the human skin through sensors.

[0107] For a detailed description of the 300 patch, please refer to the following content, which will not be elaborated here.

[0108] For example, Figure 1 (a) shows a schematic diagram of side A of the watch strap 100. Figure 1 (b) shows a schematic diagram of side B of the watch strap 100.

[0109] Here, side A refers to the side of the watch strap 100 facing the human skin when collecting physiological signals, and side B refers to the side of the watch strap 100 facing away from the human skin when collecting physiological signals.

[0110] like Figure 1 As shown in (a), the watch strap 100 may include: a watch strap body 10, a sensor module 20, a positioning marker 30, and a buckle 40. Wherein:

[0111] The main body 10 of the watch strap is the main part of the watch strap 100. The main body 10 of the watch strap can carry devices such as the sensor module 20, the positioning mark 30, and the buckle 40 to form the watch strap 100.

[0112] The sensor module 20 includes one or more sensors, through which the watchband 100 can acquire physiological signals. A detailed description of the sensor module 20 will follow. Figure 2 The details will not be elaborated here.

[0113] The positioning marker 30 can be used to visually indicate its own location. Furthermore, by setting the distance between the positioning marker 30 and the sensor module 20, as well as the size of the sensor module 20, within a specified range, the location of the sensor module 20 can be determined by observing the position of the positioning marker 30. Therefore, when the user uses the watchband 100 to collect physiological signals, by adjusting the positioning marker 30 to the specified position, the sensor module 20 can face the specified detection target on the human skin, such as a specified artery or vein, thus enabling the collection of physiological signals from the specified target.

[0114] Taking the wearing method of the watch strap 100 as wrapping around the human wrist as an example, the distance (e.g., a first distance) between the positioning mark 30 and the sensor module 20 can be within a first range. For example, the distance between the edge of the sensor module 20 close to the positioning mark 30 and the positioning mark 30 is between 6mm and 8mm. The size (e.g., a first size) of the sensor module 20 can also be within a second range. For example, the length of the sensor module 20 can be between 8mm and 10mm, and the width can be between 5mm and 8mm. In this way, when the watch strap 100 is worn on the human wrist, if the user adjusts the positioning mark 30 to a designated position on the wrist, such as the wrist side on the thumb side when the palm faces the user's face, then the sensor module 20 can face the radial artery on the user's wrist due to the pre-planned size and distance from the positioning mark 30.

[0115] The first and second ranges mentioned above can be determined based on the wrist circumference of most people and the distribution of the radial artery on the wrist. It is evident that the watchband 100 takes into account the differences in wrist circumference among people. By setting the size of the sensor module 20, it can cover the radial artery of the general population. Furthermore, the introduction of the positioning marker 30 reduces the difficulty for users to align the sensor module 20 with the designated detection target when wearing the watchband 100. Users only need to adjust the positioning marker 30 to the designated position to align the sensor module 20 with the designated detection target, obtaining more accurate physiological signals with better signal quality.

[0116] For a detailed description of the positions of the positioning marker 30 and the sensor module 20 on the wrist when the watch strap 100 is worn, please refer to the following sections. Figure 7 The relevant content in [the document / document].

[0117] Additionally, it should be noted that the specified position to which the positioning mark 30 is adjusted mentioned above is only an example of the watch strap 100 being worn on the wrist. If the watch strap 100 is worn on other parts of the body, or if the sensor module 20 is facing other detection targets, the specified position to which the positioning mark 30 is adjusted may be different, and the first range and the second range mentioned above may also be different.

[0118] For example, in order to highlight the visual prominence of the positioning mark 30, the positioning mark 30 can exist in any of the following forms:

[0119] 1) The positioning mark 30 is presented as a raised structure on the watch strap 100.

[0120] 2) The positioning mark 30 is presented as a pattern on the watch strap 100.

[0121] 3) Positioning mark 30 is a surface area that is different in color or material from the rest of the watch strap 100.

[0122] It is understood that the shape of the positioning mark 30 can also be a combination of one or more of the above shapes. For example, the positioning mark 30 can be a raised structure of a material that is different from the rest of the surface, or the positioning mark 30 can also exist in other shapes. The embodiments of this application do not limit the form of the positioning mark 30.

[0123] The buckle 40 can be used to wrap the watch strap 100 around a first part of the human body. The buckle 40 can be located at the edge of one end of the watch strap body 10. Exemplarily, the buckle 40 can be a magnetic clasp or a mechanical clasp; the form of the buckle 40 is not limited in this embodiment. If the buckle 40 is a magnetic clasp, the other end of the watch strap body 10 can be provided with a metal component, which can be used to magnetically attach to the magnetic clasp, thus wrapping the watch strap 100 around the first part of the human body. Similarly, if the buckle 40 is a mechanical clasp, the other end of the watch strap body 10 can include a locking hole, which can be used to lock the watch strap 100 around the first part of the human body.

[0124] It should be noted that the positioning mark 30 and the buckle 40 are optional components. For example, if the watch strap 100 does not need to measure a specified detection target, the positioning mark 30 is not required on the watch strap 100. Similarly, if the watch strap 100 is worn by attaching it to the skin with the patch 300, the buckle 40 is not required. It can also be understood that, besides using the buckle 40 to wrap the watch strap 100 around the first part of the body, other methods can also be used to wrap the watch strap 100 around the first part of the body without the buckle 40. For example, the main body 10 of the watch strap is a memory metal spring that can be straightened or curled under external force; when the spring is curled, it can wrap around the first part of the body.

[0125] like Figure 1 As shown in (b) above, the watch strap 100 may further include: a connecting member 50. Wherein:

[0126] The connecting component 50 can be used to fix the watch strap 100 to other components. For example, the connecting component 50 can be used to fix the watch strap 100 to the watch head 200. In this way, the watch strap 100 connected to the watch head 200 is a watch in appearance. As another example, the connecting component 50 can be used to fix the watch strap 100 to the patch 300. In this way, when the patch 300 is attached to clothing or human skin, the watch strap 100 can be fixed to the patch 300 through the connecting component 50, so that the watch strap 100 can be attached to human skin. In addition, the connecting component 50 and the sensor module 20 can be located on the same side or different sides of the watch strap 100, so that when the watch strap 100 is attached to human skin, the side of the watch strap 100 with the sensor module 20 can face the human skin.

[0127] For example, the connecting component 50 can fix the watch strap 100 to other components through magnetic field action or mechanical action. For instance, if the connecting component 50 fixes the watch strap 100 to other components through magnetic field action, the connecting component 50 may include a magnetic strip. The fixation can be achieved through the magnetic field action between the magnetic strip included on the connecting component 50 and the magnetic strips included on other components. As another example, if the connecting component 50 fixes the watch strap 100 to other components through mechanical action, the connecting component 50 can achieve this fixation through a mutually interlocking buckle structure. For example, the connecting component 50 may include two parallel slide rails with recessed structures, and other components may include two parallel, protruding crossbars. In this way, the fixing of the connecting component 50 to other components can be achieved through the mutual interlocking of the crossbars and slide rails.

[0128] in, Figure 1 (b) illustrates a specific form of the connecting member 50, with the connecting member 50 including a magnetic strip as an example.

[0129] exist Figure 1 In (b) of the above, the connecting member 50 may include two magnetic strip arrays extending along the long side of the watch strap 100 and located on the upper and lower sides of the long side of the watch strap 100, respectively. Exemplarily, one magnetic strip array may be presented as a thick serrated line.

[0130] It is understood that when the connecting component 50 includes magnetic strips, the embodiments of this application do not limit the number of magnetic strips, their placement direction, position, size, and the pattern they present. For example, the connecting component 50 may include three magnetic strip arrays, wherein each magnetic strip array may be presented as a line in which multiple magnetic strips are arranged at intervals along a straight line.

[0131] In addition, from Figure 1As can be seen from (a) and (b) in the figure, both side A and side B of the watch strap 100 can contain the positioning mark 30. In other embodiments of this application, the positioning mark 30 can be located on one side of the watch strap 100, such as side A or side B. Preferably, the positioning mark 30 can be located on side B of the watch strap 100, so that when the user wears the watch strap 100, the user can observe the positioning mark 30 more intuitively.

[0132] in addition, Figure 1 (b) also shows two areas on the watchband 100: area 1 and area 2. Optionally, a communication module 80 is provided in area 1 of the watchband 100, and a processor 60 and a power supply module 70 are provided in area 2.

[0133] It should be noted that the processor 60, power supply module 70, and communication module 80 can be located inside the watchband body 10, and these components may not be visible from the surface of the watchband 100, or some or all of their structure may be visible. For a detailed description of the processor 60, power supply module 70, and communication module 80, please refer to the following sections. Figure 5 The relevant content will not be elaborated here.

[0134] Understandable, Figure 1 The positions of regions 1 and 2 on the watchband 100 shown in (b) are merely an example. In other embodiments of this application, regions 1 and 2 may be located in other positions, and this application does not limit this.

[0135] In a specific example, see Figure 1 In (b) of the diagram, if the connecting component 50 includes two magnetic strip arrays, region 1 can be located in the middle of these two magnetic strip arrays, that is, the communication module 80 is located in the middle of these two magnetic strip arrays. This is because if the watch head 200 is connected to the watch band 100 through the connecting component 50, and the communication module 80 is located in the middle of the two magnetic strip arrays included in the connecting component 50, the distance that the signal needs to propagate when the watch band 100 and the watch head 200 communicate can be shortened as much as possible, thus improving the communication quality between the watch band 100 and the watch head 200. Furthermore, if the watch band 100 and the watch head 200 communicate via near field communication (NFC), placing the communication module 80 in the middle of these two magnetic strip arrays can also improve the success rate of communication between the watch band 100 and the watch head 200 via NFC.

[0136] In another specific example, if the connecting component 50 includes a ring-shaped array of magnetic strips, the communication module 80 can be located within the ring of the magnetic strip array. This can shorten the distance that the signal needs to travel when the watch band 100 and the watch head 200 communicate, improve the communication quality between the watch band 100 and the watch head 200, and increase the success rate of communication between the watch band 100 and the watch head 200 via NFC.

[0137] In some embodiments, region 1 on the watch strap 100 may be partially or completely open. This way, after the watch strap 100 is secured to other components, such as the watch head 200, via the connecting member 50, when the watch strap 100 is worn on the human body, the side of the watch head 200 secured to the watch strap 100 can directly face the human skin through region 1. Thus, the watch head 200 can be equipped with sensors such as photoelectric sensors and temperature sensors that require direct contact with human skin to collect physiological signals. These sensors can be located on the side of the watch head 200 secured to the watch strap 100, allowing the watch head 200 to collect physiological signals reflected by the human skin through region 1, measure the user's physiological parameters, and thereby expand the functionality of the watch head 200.

[0138] Figure 2 This is a magnified internal structure diagram of the sensor module 20 provided in an embodiment of this application.

[0139] like Figure 2 As shown, the sensor module 20 can be presented as a multi-layer structure, including: sensor array 201, first surface layer 202, first magnet array 203, second magnet array 204, and second surface layer 205.

[0140] The sensor array 201 may include one or more sensors that can be used to collect physiological signals. The sensor array 201 may be disposed on the first surface layer 202. The first magnet array 203 and the second magnet array 204 may be located in the sandwich formed by the first surface layer 202 and the second surface layer 205. The second magnet array 204 may be located on the second surface layer 205. Under the action of the magnetic field between the first magnet array 203 and the second magnet array 204, the first magnet array 203 may drive the first surface layer 202 to move closer to or away from the second surface layer 205.

[0141] For example, the first surface layer 202 can be composed of a flexible material or a rigid material, and similarly, the second surface layer 205 can be composed of a flexible material or a rigid material.

[0142] Preferably, the hardness of the second surface layer 205 can be higher than that of the first surface layer 202. In this case, the first surface layer 202 can be a flexible surface layer, and the second surface layer 205 can be a rigid backing layer.

[0143] This is because the hardness of the second surface layer 205 is higher than that of the first surface layer 202. The second surface layer 205 is not easily deformed, while the first surface layer 202 is easily deformed. Therefore, under the interaction force (e.g., repulsive force or attractive force) between the first magnet array 203 and the second magnet array 204, the first surface layer 202 deforms, causing the first surface layer 202 to move closer to or away from the second surface layer 205.

[0144] In this way, if the side of the first surface layer 202 that is away from the second surface layer 205 faces the human skin, as the first surface layer 202 moves closer to or away from the second surface layer 205, the first surface layer 202 can move the sensor array 201 located on it away from or closer to the human skin, so that the sensors contained on the sensor array 201 can fit into the human skin.

[0145] Combination Figure 1 The side of the second surface layer 205 in the sensor module 20 of the watch strap 100 that faces away from the first surface layer 202 can be disposed on the watch strap body 10, so that the side of the first surface layer 202 that faces away from the second surface layer 205 faces the human skin.

[0146] In order to achieve the magnetic field interaction between the first magnet array 203 and the second magnet array 204, each of the first magnet array 203 and the second magnet array 204 may include one or more magnets.

[0147] For example, one or more magnets in the first magnet array 203 can correspond one-to-one with one or more magnets in the second magnet array 204.

[0148] The magnets contained in the first magnet array 203 and / or the second magnet array 204 can be electromagnets. In this way, by controlling the current of the electromagnets, the magnetic field strength between the first magnet array 203 and the second magnet array 204 can be changed, thereby controlling the first surface layer 202 to move closer to or further away from the second surface layer 205.

[0149] It is understandable that the magnets included in the first magnet array 203 can be all electromagnets, all permanent magnets, or both. Similarly, the magnets included in the second magnet array 204 can be all electromagnets, all permanent magnets, or both. It is important to note that in each pair of corresponding magnets in the first magnet array 203 and the second magnet array 204, at least one magnet must be an electromagnet. This is necessary to allow the magnetic field strength between the first magnet array 203 and the second magnet array 204 to be changed by adjusting the current of that electromagnet.

[0150] In a specific example, the magnets in the first magnet array 203 can be permanent magnets, and the magnets in the second magnet array 204 can be electromagnets. Thus, the magnetic field strength between the first magnet array 203 and the second magnet array 204 can be changed by adjusting the current in the second magnet array 204.

[0151] This is because, considering that the second magnet array 204 is closer to the watch band 100 than the first magnet array 203, it is more feasible to adjust the current of the second magnet array 204 from a circuit design perspective.

[0152] In some embodiments, the first magnet array 203 and the second magnet array 204 may contain the same number of magnets, and these magnets may be arranged in a first arrangement.

[0153] For example, the first arrangement may include a Nth row and an N+1th row, with the magnets in the Nth row and the magnets in the N+1th row interspersed. Here, N is an integer greater than or equal to 1.

[0154] In other words, the magnets in the first magnet array 203 and the second magnet array 204 can be arranged in the same way, so as to ensure that there is a strong magnetic field force between the two magnet arrays.

[0155] In a specific example Figure 2 A possible schematic diagram is shown of multiple magnets in the second magnet array 204 arranged in a first configuration.

[0156] like Figure 2 As shown, see details. Figure 2 The first arrangement of the eight circles drawn in the second magnet array 204 is such that the first and third rows each have three magnets, the second row has two magnets, and the magnets in the second row are placed with gaps between them and the magnets in the first and third rows.

[0157] Understandable, Figure 2The first emission method shown is only an example, and the embodiments of this application do not limit the first emission method.

[0158] Additionally, it is worth mentioning that the sensor array 201 may contain one or more sensors. Figure 2 The sensor array 201 shown is exemplified by using four sensors (see details). Figure 2 (The four circles drawn in the sensor array 201) It should be understood that in practical applications, the sensor array 201 may contain more or fewer sensors, and the embodiments of this application do not limit this.

[0159] Furthermore, these one or more sensors may include one or more sensor types, such as pressure sensors, photoelectric sensors, etc. The location of different types of sensors within the sensor module 20 may vary.

[0160] For example, some sensors need to be in direct contact with or facing the skin without being obstructed by other components. Taking photoelectric sensors as an example, since photoelectric sensors need to emit light onto the skin through a light source, they need to be directly facing the skin when collecting physiological signals.

[0161] Assuming that sensor array 201 includes sensors that need to directly contact or face the skin, these sensors will be referred to as first sensors 2011.

[0162] Figure 3 A schematic diagram showing the position of the first sensor 2011 in the sensor module 20 is shown.

[0163] like Figure 3 As shown, the first sensor 2011 is disposed on the side of the first surface layer 202 facing away from the second surface layer 205, and the first surface layer 202 is located between the first magnet array 203 and the first sensor 2011.

[0164] In this way, under the action of the magnetic field between the first magnet array 203 and the second magnet array 204, the first magnet array 203 can indirectly drive the first sensor 2011 to move closer to or away from the second surface layer 205 while driving the first surface layer 202 to move closer to or away from the second surface layer 205.

[0165] For example, some sensors do not need to directly contact the skin, or face the skin. Take pressure sensors as an example: since pressure sensors are used to detect pressure, whether other components are placed between the skin and the pressure sensor has little impact on the pressure detection process.

[0166] Assuming that sensor array 201 includes sensors that do not need to directly contact the skin or face the skin, these sensors will be referred to as second sensors 2012 below.

[0167] Figure 4 A schematic diagram showing the position of the second sensor 2012 in the sensor module 20 is shown.

[0168] like Figure 4 As shown, the second sensor 2012 is disposed on the surface of the first surface layer 202 facing the second surface layer 205, and the second sensor 2012 is located between the first magnet array 203 and the first surface layer 202.

[0169] In this way, under the influence of the magnetic field between the first magnet array 203 and the second magnet array 204, the first magnet array 203 can directly drive the second sensor 2012 to move closer to or away from the second surface layer 205 while driving the first surface layer 202 to move closer to or away from the second surface layer 205.

[0170] It is understandable that even if the second sensor 2012 does not need to directly contact the skin, or does not need to face the skin directly, it can be placed on the side of the first surface layer 202 facing away from the second surface layer 205, similar to... Figure 3 The position of the first sensor 2011 in the sensor module 20. Preferably, the second sensor 2012 is disposed on the side of the first surface layer 202 facing the second surface layer 205, which can avoid exposing the second sensor 2012 to the outside world, thereby reducing wear and tear on the second sensor 2012 during use and extending its service life.

[0171] It should be noted that the sensor module 20 may simultaneously include the first sensor 2011 and the second sensor 2012, wherein both the first sensor 2011 and the second sensor 2012 may include one or more sensors. This application embodiment does not limit the type and number of sensors included in the sensor module 20. In addition, one or more sensors included in the sensor module 20 may also be disposed between the second magnet array 204 and the second surface layer 205. This application embodiment does not limit the position of the sensors included in the sensor module 20.

[0172] Figure 5 for Figure 1 The cross-sectional view of the watch strap 100 shown in (a) at section line CC is a cross-sectional view of one embodiment.

[0173] like Figure 5 As shown, a communication module 80 is installed in area 1 of the watch band 100, and a processor 60 and a power supply module 70 are installed in area 2 of the watch band 100. Wherein:

[0174] The communication module 80 can be used to establish communication connections with other devices and realize data communication with other devices, such as sending physiological signals collected by the sensor array 201 to other devices, and / or receiving instructions from other devices to collect physiological signals.

[0175] Specifically, the communication connection can be a wired connection or a wireless connection. The wireless connection can be a short-range connection such as a high-fidelity wireless communication (Wi-Fi) connection, a Bluetooth connection, an infrared connection, an NFC connection, or a ZigBee connection, or a long-range connection, including but not limited to long-range connections based on mobile networks based on 2G, 3G, 4G, 5G and subsequent standard protocols.

[0176] Preferably, the communication connection can be wireless. This eliminates the need for a wired connection between the watchband 100 and other devices, allowing it to be used as a standalone device and improving ease of use for measuring physiological parameters.

[0177] The power supply module 70 can be used to charge and supply power to the watch band 100. For example, the power supply module 70 can charge the watch band 100 wirelessly.

[0178] The processor 60 can be used to adjust the current of the first magnet array 203 and / or the second magnet array 204, thereby controlling the degree to which the first surface layer 202 approaches or moves away from the second surface layer 205, so that the sensor array 201 can collect physiological signals when it is in a specified degree of contact with human skin.

[0179] In one possible implementation, the degree of contact between the sensor array 201 and the human skin can be represented by the contact pressure between the sensor array 201 and the human skin.

[0180] In other words, the sensor array 201 may include a pressure sensor 2013, which can be used to detect pressure. One or more sensors in the sensor array 201 can collect physiological signals when the pressure detected by the pressure sensor 2013 meets a specified condition (e.g., a first condition). These one or more sensors may or may not include the pressure sensor 2013; the inclusion of the pressure sensor 2013 depends on the physiological parameter being measured. For example, if the physiological parameter being measured is blood pressure, the pressure sensor 2013 can be used to collect the pressure value reflected by the pulse when the pressure detected by the pressure sensor 2013 meets the specified condition, and this pressure value can be used to calculate the user's blood pressure. As another example, if the physiological parameter being measured is blood oxygen saturation, a photoelectric sensor can be used to collect a PPG signal when the pressure detected by the pressure sensor 2013 meets the specified condition, and this PPG signal can be used to calculate the user's blood oxygen saturation.

[0181] For example, the specified condition may refer to the contact pressure detected by the pressure sensor 2013 with human skin being greater than a threshold, less than a threshold, or within a preset range, etc.

[0182] Accordingly, the processor 60 can be used to adjust the current of the first magnet array 203 and / or the second magnet array 204 based on the pressure detected by the pressure sensor 2013, so that the pressure detected by the pressure sensor 2013 meets the specified condition.

[0183] Taking the processor 60 adjusting the current of the second magnet array 204 as an example, assuming that the greater the current of the second magnet array 204, the greater the pressure detected by the pressure sensor 2013, in order to control the pressure detected by the pressure sensor 2013 to meet the specified conditions, the processor 60 can reduce the current of the second magnet array 204 when the pressure is too high, and increase the current of the second magnet array 204 when the pressure is too low.

[0184] In this way, the processor 60 can control the sensor module 20 to be in a specified fit with the human skin to collect physiological signals, ensuring that the sensor module 20 can collect more accurate physiological signals with higher signal quality.

[0185] It should be noted that if the sensor module 20 contains multiple sensors, the optimal degree of contact between the different sensors and the human skin may vary when collecting physiological signals. That is, the pressure detected by the pressure sensor 2013 needs to meet different specified conditions. The processor 60 can determine the specified conditions based on the physiological parameters that need to be measured.

[0186] In one possible example, the watchband 100 may pre-store specified conditions corresponding to different sensors. When the sensor module 20 uses a certain sensor to collect physiological signals, it can find the specified conditions corresponding to the currently used sensor by using the pre-stored specified conditions corresponding to different sensors.

[0187] In the embodiments of this application, the pressure sensor 2013 mentioned above may also be referred to as the third sensor 2013.

[0188] In another possible implementation, the degree of contact between the sensor array 201 and the human skin can be represented by the signal quality of the physiological signals collected by the sensors in the sensor array 201.

[0189] For example, if the quality of the physiological signals collected by the sensor is high, it indicates that the sensor array 201 is in good contact with the human skin; if the quality of the physiological signals collected by the sensor is low, it indicates that the contact between the sensor array 201 and the human skin is poor.

[0190] In other words, in addition to adjusting the current of the first magnet array 203 and / or the second magnet array 204 based on the pressure detected by the third sensor 2013, the current of the first magnet array 203 and / or the second magnet array 204 can also be adjusted based on the signal quality of the physiological signal collected by the third sensor 2013. In this case, the third sensor 2013 is not limited to a pressure sensor, but can refer to any one or more sensors included in the sensor array 201.

[0191] Taking the adjustment of the current of the first magnet array 203 as an example, if increasing the current of the first magnet array 203 would reduce the signal quality of the physiological signal collected by the third sensor 2013, then the processor 60 can decrease the current of the first magnet array 203. Conversely, if decreasing the current of the first magnet array 203 would reduce the signal quality of the physiological signal collected by the third sensor 2013, then the processor 60 can increase the current of the first magnet array 203. In this way, the processor 60 can adjust the current of the first magnet array 203 and / or the second magnet array 204 to ensure that the signal quality of the physiological signal collected by the third sensor 2013 is greater than a threshold.

[0192] It is understood that, in addition to the pressure magnitude mentioned above, the degree of contact between the sensor array 201 and the human skin can also be reflected in other ways, such as the signal quality of physiological signals. This application embodiment does not limit this.

[0193] Figure 6 This is a schematic diagram of the header 200 provided in an embodiment of this application.

[0194] in, Figure 6 (a) shows a schematic diagram of face D of the header 200. Figure 6 (b) shows a schematic diagram of face E of header 200.

[0195] For example, with reference to the watch head 200 being fixed to the watch strap 100, the D side of the watch head 200 can refer to the side facing away from the watch strap 100, and the E side of the watch head 200 can refer to the side facing the watch strap 100.

[0196] like Figure 6 As shown in (a), the meter header 200 may include a display screen 2001. The display screen 2001 may include one or more of the following functions:

[0197] 1) The display screen 2001 can be used to display physiological parameters determined based on physiological signals.

[0198] For example, the physiological signal can be a signal sent from the watch strap 100 to the watch head 200 via the communication module 80. In this way, the user can view their own physical condition through the display screen 2001.

[0199] 2) This display screen 2001 can be used to display the relevant user interface for measuring physiological parameters.

[0200] The meter head 200 can initiate the measurement of physiological parameters based on user operations on the relevant user interface, such as touch operations on the display screen 2001. At this time, the meter head 200 can send the instruction to measure the physiological parameters to the watch band 100, thereby controlling the watch band 100 to start collecting physiological signals.

[0201] It can also be seen that the meter head 200 also includes a communication module 2003 (not shown in the figure), which can be used to receive physiological signals collected by the watch band 100 and / or send instructions to the watch band 100 to measure physiological parameters.

[0202] like Figure 6 As shown in (b), the watch head 200 may also include a connecting member 2002. The connecting member 2002 can be used to secure the watch head 200 to the watch strap 100.

[0203] Similar to the description of the connecting component 50 in the watch strap 100, the connecting component 2002 can be connected to the connecting component 50 on the watch strap 100 through principles such as magnetic field action or mechanical action, thereby fixing the watch head 200 to the watch strap 100. For details, please refer to the relevant description of the connecting component 50 above; it will not be repeated here.

[0204] in, Figure 6(b) illustrates a specific form of a connecting member 2002, taking the connecting member 2002 including a magnetic strip as an example.

[0205] exist Figure 6 In (b), the connecting component 2002 may include two magnetic strip arrays that extend along the long side of the meter head 200 and are located on the upper and lower sides of the long side of the meter head 200, respectively.

[0206] For example, both magnetic strip arrays can be presented as a thick serrated line.

[0207] For example, the spacing between the two magnetic strip arrays included in the connecting member 2002 is equal to the spacing between the two magnetic strip arrays included in the connecting member 50.

[0208] For example, when the watch head 200 is fixed to the watch strap 100, the magnetic strip array included in the connecting component 2002 should correspond one-to-one with the magnetic strip array included in the connecting component 50, and the corresponding magnetic strips should overlap in position to achieve stable fixing of the watch head 200 and the watch strap 100.

[0209] In one implementation, if both the connecting component 50 on the watch strap 100 and the connecting component 2002 on the watch head 200 include a magnetic strip, and the watch strap 100 and the watch head 200 are fixed by a magnetic field, then the magnetic field range of the magnetic strip of the connecting component 50 can be greater than the magnetic field range of the magnetic strip of the connecting component 2002. In this way, when the watch head 200 is fixed to the watch strap 100, fine-tuning of the position of the watch head 200 can be achieved, so that when the user wears the watch strap 100 with the watch head 200 fixed on it, the position of the watch head 200 on the human body can be adjusted according to their needs without adjusting the watch strap 100 itself.

[0210] In a specific example, if the connecting part 50 on the watch strap 100 is Figure 1 The two magnetic strip arrays shown in (b) have a connecting part 2002 on the meter head 200. Figure 6 The length of the magnetic strip array included in the connecting member 50, as shown in (b), can be greater than the length of the magnetic strip array included in the connecting member 2002. In this way, when the watch head 200 is fixed on the watch strap 100, the position of the watch head 200 on the watch strap 100 can be adjusted along the direction of the long side of the watch strap 100.

[0211] Understandable, Figure 6 The magnetic strip shown in (b) is just an example. When the meter head 200 includes a magnetic strip, the embodiments of this application do not limit the number of magnetic strips, their orientation, position, size, and the graphic they present on the array of magnetic strips included on the meter head 200.

[0212] For example, Figure 7 This is a schematic diagram of wearing the watch strap 100 on the wrist, provided as an embodiment of this application.

[0213] in, Figure 7 (a) shows a schematic diagram of the watch strap 100 being worn on the wrist when the watch strap 100 and the watch head 200 are not fixed together. Figure 7 (b) shows a schematic diagram of the watch strap 100 being worn on the wrist when the watch strap 100 is fixed together with the watch head 200. Figure 7 (c) shows a schematic diagram of the inside of the wrist when the watch strap 100 is worn on the wrist.

[0214] like Figure 7 As shown in (c), when the watch strap 100 is worn on the wrist, the positioning mark 30 can be located at... Figure 7 As shown in (c) of the image, the sensor module 20 located on the skin-facing side of the watchband 100 can face the radial artery on the wrist.

[0215] In some embodiments, the watch strap 100 may further include a tension structure 90, which may be located on the watch strap body 10 and can be used to extend the length of the watch strap 100.

[0216] For example, Figure 8 This is a schematic diagram of another embodiment of the watch strap 100 provided in this application.

[0217] in, Figure 8 (a) shows a schematic diagram of the watch strap 100 before the stretching structure 90 is stretched. Figure 8 (b) shows a schematic diagram of the watch strap 100 after the stretching structure 90 is stretched.

[0218] The tension structure 90 can be located at any position on the watch strap 100. For example, the tension structure 90 can be located at the edge of one end of the watch strap body 10.

[0219] contrast Figure 8 As can be seen from (a) and (b), after the stretching structure 90 is stretched, the length of the watch strap 100 becomes longer, which expands the wearing scenarios of the watch strap 100, in addition to... Figure 7 The wearing method shown allows the watch strap 100 to be worn not only on the wrist, but also on the arm, waist, or other parts of the body with a longer circumference. Furthermore, for some users with thicker wrists, the strap 100 can also be worn on the wrist by adjusting the stretching structure 90.

[0220] It is understood that the location of the tension structure 90 is not limited in this application embodiment. The tension structure 90 can be located at the edge of one end of the watch strap body 10 or at the middle of the watch strap body 10. In one possible implementation, any area in the watch strap body 10 without electrical connections can be used to install the tension structure 90. In addition, if the watch strap 100 includes a positioning mark 30, the tension structure 90 can be located outside the area between the sensor module 20 and the positioning mark 30. This avoids the tension structure 90's extension or retraction changing the distance between the sensor module 20 and the positioning mark 30, thereby preventing it from affecting the user's positioning of the target using the positioning mark 30.

[0221] Furthermore, the stretch structure 90 included on the watch strap 100 may include one or more, thereby further extending the length of the watch strap 100.

[0222] For example, Figure 9 This is a schematic diagram of another embodiment of the watch strap 100 provided in this application.

[0223] like Figure 9 As shown, the watch strap 100 may include two tension structures 90, which may be located at both ends of the watch strap 100.

[0224] It is understood that the number of tension structures 90 included on the strap 100 in the embodiments of this application is not limited.

[0225] In some embodiments, the watch strap 100 can also be extended by connecting it to other components, so that the watch strap 100 can be worn around a longer part of the body.

[0226] For example, the watch strap 100 may also include a locking structure located at one edge of the watch strap body 10. The watch strap 100 can be extended by connecting an external strap through this locking structure.

[0227] Figure 10 by Figure 8 Taking the watch strap 100 shown as an example, a schematic diagram of wearing a watch strap 100 provided in this application embodiment is shown.

[0228] like Figure 10 As shown, the watch strap 100 can be worn on the user's upper arm.

[0229] Additionally, it should be noted that if the watch band 100 includes a positioning mark 30, when the user wears the watch band 100 on their upper arm, the positioning mark 30 can be adjusted to a specific position so that the sensor module 20 on the watch band 100 can face the brachial artery on the arm.

[0230] In some implementations, the watch strap 100 can be applied to human skin using a patch 300.

[0231] Figure 11 This is a schematic diagram of one embodiment of the patch 300 provided in this application.

[0232] like Figure 11 As shown, the patch 300 may include a connecting member 3001. The connecting member 3001 can be used to fix the patch 300 to the watch strap 100. Specifically, the patch 300 can be fixed to the watch strap 100 by fixing the connecting member 3001 to a connecting member (e.g., connecting member 50) on the watch strap 100.

[0233] Similar to the description of the connecting component 50 in the watch strap 100, this connecting component 3001 can fix the patch 300 to the watch strap 100 through principles such as magnetic field action or mechanical action. For details, please refer to the relevant description of the connecting component 50 above; it will not be repeated here.

[0234] in, Figure 11 Taking the connection component 3001 including a magnetic strip as an example, a specific form of the connection component 3001 is illustrated.

[0235] exist Figure 11 In this connection, the connecting component 3001 may include two magnetic strip arrays, which are parallel to each other and located on opposite sides of the patch 300. For example, both magnetic strip arrays may be presented as a thick serrated line.

[0236] Understandably, the shape of the patch 300, besides being for... Figure 11 Besides the rounded rectangle shown, the shapes can also be circles, triangles, etc., and this application does not limit them in this embodiment.

[0237] in, Figure 11 The schematic diagram shown is a view of the side of the patch 300 facing the watch strap 100 when it is fixed to the watch strap 100, while the other side of the patch 300 can be used to fix it to human skin or clothing. For example, the side of the patch 300 that is fixed to human skin or clothing can be adhesive, and the patch 300 can be used to adhere to human skin or clothing using this adhesive side.

[0238] It is understood that, not limited to adhesive methods, the patch 300 can also be fixed to human skin or clothing in other ways, and this application embodiment does not limit this.

[0239] Specifically, taking the patch 300 being attached to human skin or clothing as an example, when the patch 300 is attached to human skin and when the patch 300 is attached to clothing, the position of the connecting part 50 on the strap 100 for fixing the patch 300 may be different, which will be described in detail below:

[0240] 1) Apply patch 300 to the inside of the garment.

[0241] To distinguish it from the connecting parts on the watch strap 100 used to fix the patch 300 to human skin when the patch 300 is attached to human skin, the connecting parts on the watch strap 100 used to fix the patch 300 to human skin are referred to here as the first connecting part 501.

[0242] Figure 12 This is a schematic diagram showing the position of the first connecting component 501 on the watch strap 100, as provided in an embodiment of this application.

[0243] like Figure 12 As shown, the first connecting component 501 and the sensor module 20 can be located on different sides of the watchband 100. Following the above... Figure 1 In the terminology used, sensor module 20 may be located on side A of watchband 100, and first connecting member 501 may be located on side B of watchband 100.

[0244] Figure 13 This is an exploded view of the watch strap 100 provided in an embodiment of this application.

[0245] like Figure 13 As shown, the patch 300 and the watch strap 100 are located between the user's skin and the user's clothing. The adhesive side of the patch 300 faces the inside of the clothing, the side of the patch 300 with the connecting member 3001 faces the watch strap 100, the side of the watch strap 100 with the first connecting member 501 faces the patch 300, and the side of the watch strap 100 with the sensor module 20 faces the human skin. Furthermore, taking an example where both the connecting member 3001 and the first connecting member 501 include magnetic strips, the watch strap 100 is fixed to the patch 300 through the magnetic field interaction between the magnetic strip in the first connecting member 501 and the magnetic strip included in the connecting member 3001 on the patch 300.

[0246] For example, the spacing between the two magnetic strip arrays included in the connecting member 3001 may be equal to the spacing between the two magnetic strip arrays included in the first connecting member 501.

[0247] For example, when the patch 300 is fixed to the watch strap 100, the magnetic strip array included in the connecting component 3001 should correspond one-to-one with the magnetic strip array included in the first connecting component 501, and the corresponding magnetic strips should overlap in position to achieve stable fixing of the patch 300 and the watch strap 100.

[0248] from Figure 13 As can be seen, after the user applies the watch strap 100 to the human skin through the patch 300, the area projected onto the human skin by the sensor module 20 on the watch strap 100 is region 3, and the watch strap 100 can collect physiological signals in region 3 of the human skin through the sensor module 20.

[0249] For example, the clothing used to attach the patch 300 can be a bodysuit. After the patch 300 is attached to the inside of the bodysuit, the close fit of the bodysuit allows the watch strap 100 fixed to the patch 300 to fit snugly against the human skin. Thus, even if the watch strap 100 is not worn around the body through the buckle 40, the watch strap 100 can still be stably attached to the human skin, enabling successful measurement of physiological parameters.

[0250] In some embodiments, the first connecting member 501 and the connecting member 50 in the watch strap 100 can be the same device. That is, the connecting member 50 on the watch strap 100 can be used to fix the watch strap 100 to the watch head 200, and can also be used to fix the watch strap 100 to the patch 300. It can be seen that the user can reuse the connecting member 50 to fix the watch strap 100 to different devices, thereby using the same device to achieve multiple wearing methods of the watch strap 100.

[0251] In other embodiments, the first connecting member 501 and the connecting member 50 in the watch strap 100 can be different devices, and one or more of the first connecting member 501 and the connecting member 50 can be provided on the watch strap 100. Wherein, if the watch strap 100 is provided with the connecting member 50, the watch strap 100 can be fixed together with the watch head 200 through the connecting member 50; if the watch strap 100 is provided with the first connecting member 501, the watch strap 100 can be fixed together with the patch 300 through the first connecting member 501.

[0252] 2) The patch 300 is applied to human skin.

[0253] To distinguish it from the connecting part on the watch strap 100 used to fix the patch 300 to the inside of the garment, the connecting part on the watch strap 100 used to fix the patch 300 to the garment is referred to as the second connecting part 502.

[0254] Figure 14This is a schematic diagram showing the position of the second connecting component 502 on the watch strap 100, as provided in an embodiment of this application.

[0255] like Figure 14 As shown, the first connecting component 501 and the sensor module 20 can be located on the same side of the watch strap 100. Following the above... Figure 1 In the terminology used, the first connecting component 501 and the sensor module 20 may be located on side A of the watch strap 100.

[0256] Figure 15 This is an exploded view of the watch strap 100 provided in an embodiment of this application.

[0257] like Figure 15 As shown, the patch 300 is located between the watch strap 100 and the human skin. The adhesive side of the patch 300 faces the human skin, the side of the patch 300 with the connecting member 3001 faces the watch strap 100, and the side of the watch strap 100 with the second connecting member 502 faces the patch 300. Furthermore, taking an example where both the connecting member 3001 and the second connecting member 502 include magnetic strips, the watch strap 100 is fixed to the patch 300 through the magnetic field interaction between the magnetic strip in the second connecting member 502 and the magnetic strip in the connecting member 3001 on the patch 300.

[0258] For example, the spacing between the two magnetic strip arrays included in the connecting member 3001 may be equal to the spacing between the two magnetic strip arrays included in the second connecting member 502.

[0259] For example, when the patch 300 is fixed to the watch strap 100, the magnetic strip array included in the connecting component 3001 should correspond one-to-one with the magnetic strip array included in the second connecting component 502, and the corresponding magnetic strips should overlap in position to achieve stable fixing of the patch 300 and the watch strap 100.

[0260] from Figure 15 As can be seen, since the sensor module 20 and the second connecting component 502 are located on the same side of the watch strap 100, after the user applies the watch strap 100 to the human skin through the patch 300, the sensor module 20 on the watch strap 100 faces the human skin, and the area projected onto the human skin by the sensor module 20 is region 4. The watch strap 100 can collect physiological signals in region 4 of the human skin through the sensor module 20.

[0261] In some embodiments, the watch strap 100 may be provided with one or more of a second connecting member 502 and a connecting member 50. Wherein, if the watch strap 100 is provided with a connecting member 50, the watch strap 100 can be fixed together with the watch head 200 through the connecting member 50; if the watch strap 100 is provided with a first connecting member 501, the watch strap 100 can be fixed together with the patch 300 through the first connecting member 501.

[0262] In a specific example, if the watch strap 100 is provided with both the second connecting part 502 and the connecting part 50, then the watch strap 100 can be fixed to both the watch head 200 and the patch 300 at the same time. In this case, the watch strap 100 can not only be applied to the human skin through the patch 300, but the watch head 200 is also fixed to the watch strap 100.

[0263] In some embodiments, the patch 300 can be applied to the skin covered by the clothing when the user is wearing a tight-fitting garment. This is because the tight-fitting garment allows the watch strap 100 to fit more closely to the human skin. In this way, even if the watch strap 100 is not worn around the body through the buckle 40, the watch strap 100 can still be stably attached to the human skin, enabling successful measurement of physiological parameters.

[0264] from Figures 11-15 It can be seen that whether the patch 300 is fixed to human skin or clothing, it is suitable for various applications. Figure 11 The patch 300 shown allows the watch strap 100 to be worn on the skin in a way that is more suitable for users who wear tight-fitting sportswear for sports activities such as cycling, swimming, fitness, running, etc.

[0265] It is understandable that the above Figure 13 and Figure 15 In the described wearing methods, each example uses one patch 300. In other embodiments of this application, the watch strap 100 can be used with multiple patches 300 to achieve application to human skin. In this case, the first connecting member 501 or the second connecting member 502 on the watch strap 100 includes one or more. Furthermore, the embodiments of this application do not limit the position of the first connecting member 501 and the second connecting member 502. In addition, the watch strap 100 can be provided with both the first connecting member 501 and the second connecting member 502 simultaneously.

[0266] It is worth mentioning that the above Figure 13 and Figure 15The two ways of wearing the watch strap 100 with the patch 300 are merely illustrative examples. In other embodiments of this application, there may be other ways of wearing the patch 300 and the watch strap 100. For example, the patch 300 may be attached to the outside of clothing, and the watch strap 100 may be located between the clothing and the human skin. It should be understood that any way of wearing the watch strap 100 with other accessories so that it is attached to the human skin should fall within the protection scope of this application.

[0267] In addition, when patch 300 is applied to human skin, patch 300 is not limited to Figure 11 The shape shown Figure 16 This is a schematic diagram illustrating another embodiment of the patch 300 provided in this application.

[0268] like Figure 16 As shown, the middle area of ​​patch 300, i.e. Figure 16 The area 5 shown is hollowed out, and the area 5 is located in the middle of the two magnetic strip arrays included in the connecting member 3001. Correspondingly, the sensor module 20 on the strap 100 can be located in the middle of the two magnetic strip arrays included in the connecting member 50.

[0269] In this way, when the watchband 100 is applied to the human skin via the patch 300, the sensor module 20 on the watchband 100 can directly face the human skin through area 5. Compared to Figure 15 The sensor module 20 shown is located on the side of the patch 300. Figure 16 The patch 300 shown enables the sensor module 20 to fit more closely to human skin and achieve successful measurement of physiological parameters without the need for the external force of a tight-fitting garment, thus expanding the application scenarios of the solution.

[0270] It should be noted that the above Figures 12-16 The watch strap 100 shown may also include one or more of the following components: positioning mark 30, watch buckle 40, processor 60, power supply module 70, communication module 80, and tension structure 90. These can be referred to in the relevant content above, and will not be repeated here.

[0271] In some implementations, the watch band 100 can establish a connection with a terminal device (such as a mobile phone, tablet, etc.) through the communication module 80. In this way, the watch band 100 can send the collected physiological signals to the terminal device, and the terminal device can display the physiological signals in real time, and / or the physiological parameters determined based on the physiological signals, so that the user can understand his or her own physical condition.

[0272] For example, Figure 17 The user interface 17 displayed by the terminal device provided in this application embodiment after acquiring the physiological signals collected by the watchband 100.

[0273] like Figure 17 As shown, the user interface 17 may include: a device connection window 171, a signal waveform display window 172, and a physiological parameter display area 173. Wherein:

[0274] The device connection window 171 can be used to display the connection status between the watch strap 100 and the terminal device.

[0275] The signal waveform display window 172 can be used to display a waveform diagram based on the pulse wave signal, which can be a physiological signal collected by the sensor module 20 in the watchband 100.

[0276] The physiological parameter display area 173 can be used to display one or more physiological parameters determined based on physiological signals collected by the watchband 100, such as heart rate, standard deviation of neural intervals (SDNN) in heart rate variability (HRV), blood oxygen, blood pressure, etc. For example, in Figure 17 In the user interface 17 shown, the heart rate is 86 bpm, the HRV-SDNN is 102 ms, the blood oxygen is 98%, and the systolic blood pressure is 117 mmHg and the diastolic blood pressure is 81 mmHg.

[0277] Understandable, Figure 17 The user interface 17 shown is merely an example and does not constitute a limitation on the embodiments of this application.

[0278] Figure 18 This is a schematic flowchart of a method for acquiring physiological signals provided in an embodiment of this application.

[0279] like Figure 18 As shown, the method may include the following steps:

[0280] S101. The watch strap 100 receives the instruction to collect the first signal.

[0281] The watch strap 100 is worn on the human body, and the watch strap 100 can be worn in one or more of the following ways:

[0282] 1) The watch strap wraps around the first part of the body.

[0283] 2) The watch strap 100 is applied to the skin using a patch 300.

[0284] For details on how to wear the watch strap 100, please refer to the above. Figure 1 The relevant content will not be repeated here.

[0285] The first signal may include one or more physiological signals, such as pressure signals, PPG signals, oscillating wave signals, etc.

[0286] For example, the watchband 100 may receive the instruction to collect the first signal in several ways:

[0287] 1) The instruction to acquire the first signal can be sent from other devices to the watchband 100.

[0288] Other devices may refer to devices such as meter header 200 or terminal devices.

[0289] In this case, other devices can establish a communication connection with the watchband 100 and send the instruction to collect the first signal to the watchband 100 through the communication connection.

[0290] In other words, users can control the watch strap 100 to start collecting physiological signals through other devices.

[0291] 2) The command to acquire the first signal can be a command generated by the watch strap 100.

[0292] In this case, the watchband 100 can generate the instruction to acquire the first signal when a specified operation is detected or a specified condition is identified.

[0293] For example, the watch strap 100 can generate the instruction to collect the first signal when it detects that the watch strap 100 is being worn on a person. For instance, the watch strap 100 can identify whether it is being worn on a person by collecting a PPG signal. Or, for another example, the watch strap 100 can identify whether it is being worn on a person by detecting temperature and determining whether that temperature is skin temperature.

[0294] In other words, users can directly interact with the watchband 100 to enable it to collect physiological signals, or the watchband 100 can automatically enable it to collect physiological signals.

[0295] The first signal can be a preset physiological signal in the watchband 100, a physiological signal set by other devices, or a physiological signal selected by the user, etc. The method of determining the first signal is not limited in this application embodiment.

[0296] For example, if the instruction to acquire the first signal is sent from the meter head 200 to the meter band 100, the first signal can be the physiological signal required to measure the first physiological parameter, which can be the physiological parameter that the user determines to be measured at present through the meter head 200.

[0297] Furthermore, in some embodiments, before the watch band 100 receives the instruction to collect the first signal, the watch band 100 may send information about the sensors it contains to the watch head 200, so that the watch head 200 can understand the sensors contained in the watch band 100 based on the information, and thus determine the physiological parameters that the watch band 100 can measure. In other words, the watch head 200 can determine the instruction to collect the first signal based on the information from the sensors.

[0298] For example, after the watch head 200 obtains information from the sensors contained in the watch band 100, the watch head 200 can display the physiological parameters that the watch band 100 can measure through the display screen 2001 for the user to select.

[0299] In a specific example, if the meter head 200 can also perform measurements of some physiological parameters, then the meter head 200 and the watch band 100 can cooperate to complete the measurement of the specified physiological parameter. For example, if the measurement of a certain physiological parameter requires physiological signals collected by multiple sensors, the meter head 200 can determine the physiological signals collected by the meter head 200 and the physiological signals collected by the watch band 100 based on its own sensors and the sensors included in the watch band 100. Thus, when the meter head 200 sends a command to the watch band 100 to collect the first signal, it will also initiate the collection of the specified physiological signal itself. As another example, if the meter head 200 and the watch band 100 contain the same sensors, the meter head 200 can control the watch band 100 and the meter head 200 to simultaneously collect the same physiological signals. Thus, the meter head 200 can use the physiological signals collected by the watch band 100 to calibrate the physiological signals collected by the meter head 200, or vice versa.

[0300] In other words, when both the watch band 100 and the meter head 200 have the function of measuring physiological parameters, the watch band 100 and the meter head 200 can cooperate with each other to measure the physiological parameters. Among them, when measuring physiological parameters, the physiological signals collected by the watch band 100 and the meter head 200 can be determined by the meter head 200, the watch band 100, or the user.

[0301] S102. Under the influence of the magnetic field between the first magnet array 203 and the second magnet array 204, the watch strap 100 drives the first surface layer 202 to move closer to or further away from the second surface layer 205 through the first magnet array 203.

[0302] The watch strap 100 includes a sensor module 20, which includes a sensor array 201, a first surface layer 202, a first magnet array 203, a second magnet array 204, and a second surface layer 205.

[0303] For a detailed description of sensor module 20, please refer to the above. Figure 1 , Figure 2 , Figure 3 and Figure 4 The relevant content will not be repeated here.

[0304] The first magnet array 203 and the second magnet array 204 each include one or more magnets, including electromagnets. By adjusting the current of the electromagnets, the magnetic field strength between the first magnet array 203 and the second magnet array 204 can be changed, thereby adjusting the degree to which the first surface layer 202 moves closer to or further away from the second surface layer 205.

[0305] S103. As the first surface layer 202 moves closer to or further away from the second surface layer 205, the watchband 100 adjusts the current of the first magnet array 203 and / or the second magnet array 204 according to the second signal collected by the third sensor 2013 in the sensor array 201. The current is used to adjust the magnetic field strength between the first magnet array 203 and the second magnet array 204.

[0306] The sensor array 201 includes a third sensor 2013. Since the sensor array 201 is disposed on the first surface layer 202, as the first surface layer 202 moves closer to or away from the second surface layer 205, the sensor array 201 can also move closer to or away from the second surface layer 205 in accordance with the deformation of the first surface layer 202.

[0307] Therefore, when the watch strap 100 is worn on the human body, the sensor array 201 can follow the deformation of the first surface layer 202, moving away from or closer to the human skin.

[0308] The second signal is acquired by the third sensor 2013, which can reflect the degree to which the sensor array 201 is close to or far from human skin.

[0309] For example, the third sensor 2013 can be a pressure sensor, and the second signal is the pressure detected by the pressure sensor. The magnitude of the pressure can reflect the degree to which the sensor array 201 is close to or far from human skin.

[0310] For example, the third sensor 2013 can refer to any one of the sensors in the sensor array 201. Since the sensor array 201 affects the signal quality of the physiological signals collected by the sensor under different degrees of contact with human skin, the signal quality of the second signal can be used to reflect the degree to which the sensor array 201 is close to or far from human skin.

[0311] The watch band 100 also includes a processor 60. For a detailed description of the processor 60, please refer to the above. Figure 5 The relevant content will not be repeated here.

[0312] Since the sensor module 201 needs to be in a specified degree of contact with human skin to collect stable and high-quality physiological signals, the processor 60 can adjust the current of the first magnet array 203 and / or the second magnet array 204 to control the sensor module 201 to be in a specified degree of contact with human skin.

[0313] For example, if the magnets in the first magnet array 203 are permanent magnets and the magnets in the second magnet array 204 are electromagnets, the processor 60 can adjust the current of the second magnet array 204, thereby adjusting the degree to which the sensor array 201 is close to or far from human skin, that is, changing the second signal collected by the third sensor 2013.

[0314] S104. When the second signal meets the first condition, the watchband 100 acquires the first signal through one or more sensors in the sensor array 201.

[0315] Specifically, when the second signal acquired by the third sensor 2013 meets the first condition, one or more sensors in the sensor array 201 can acquire stable physiological signals with high signal quality. At this time, the processor 60 can keep the magnetic field strength between the first magnet array 203 and the second magnet array 204 unchanged and control one or more sensors in the sensor array 201 to acquire the first signal.

[0316] The one or more sensors may or may not include the third sensor 2013. Similarly, the first signal may or may not include the second signal.

[0317] This first condition can be a pre-defined condition set by the developer.

[0318] If the signal quality of the second signal is used to reflect the degree to which the sensor array 201 is close to or far from human skin, then the specified condition can be that the signal quality of the second signal is greater than a threshold. Furthermore, preferably, the third sensor 2013 can be one of one or more sensors used to acquire the first signal.

[0319] If the third sensor 2013 is a pressure sensor and the second signal is a pressure signal, then the first condition can be that the pressure collected by the pressure sensor is within a preset range.

[0320] For example, different sensors may have different optimal fits to human skin when collecting physiological signals, that is, the specified conditions that the second signal needs to meet may be different. The processor 60 can determine the specified conditions specifically based on the physiological parameters that need to be measured at present.

[0321] In one possible example, the watchband 100 may pre-store specified conditions corresponding to different sensors. When the sensor module 20 uses a certain sensor to collect physiological signals, it can find the specified conditions corresponding to the currently used sensor by using the pre-stored specified conditions corresponding to different sensors.

[0322] As can be seen from steps S101-S104, the watchband 100 can adjust the degree to which the sensor module 20 is close to and far from the human skin by using the physiological signals collected by the sensor, thereby achieving the optimal fit and obtaining stable and high-quality physiological signals by using the sensor to collect the physiological signals reflected by the human skin.

[0342] The memory 220 may include one or more random access memories (RAM) and one or more non-volatile memories (NVM).

[0343] The random access memory can be directly read and written by the processor 210. It can be used to store executable programs (such as machine instructions) of the operating system or other running programs, as well as user and application data.
