Description

[0001] This application is a divisional application. The original application has the application number 202210141000.8 and the original application date is February 16, 2022. The entire contents of the original application are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electronic device technology, and in particular to a watch strap assembly. Background Technology

[0003] Electronic devices used to measure blood pressure (such as blood pressure watches or wristbands) are smaller and lighter, allowing for prolonged wear and meeting the need for continuous, real-time blood pressure monitoring. The basic principle of a blood pressure watch is that when worn on the wrist, the air bladder on the watchband is in close contact with the user's radial artery. The pressure in the air bladder can be considered approximately equal to the pressure in the radial artery. The blood pressure watch determines the user's blood pressure by detecting the pressure in the air bladder. This blood pressure value can include both systolic blood pressure (SBP) and diastolic blood pressure (DBP).

[0004] Typically, a blood pressure watch consists of a main body and an air bladder strap. However, users may assemble the wrong air bladder strap into the main body, affecting the accuracy of the blood pressure measurement. Summary of the Invention

[0005] This application provides a watchband assembly designed to improve the accuracy of blood pressure measurement.

[0006] Firstly, a watch strap assembly is provided. The watch strap assembly includes a first watch strap and a second watch strap; the first watch strap includes a first air bladder and a first magnet, with a first magnetic pole of the first magnet disposed near a mounting portion of the first watch strap, the mounting portion of the first watch strap being used for detachable connection of the first watch strap to the watch body; the second watch strap includes a second air bladder and a second magnet, with a second magnetic pole of the second magnet disposed near the mounting portion of the second watch strap, the mounting portion of the second watch strap being used for detachable connection of the second watch strap to the watch body; the lengths of the first and second air bladders are different; the first and second magnetic poles are different, so that a Hall sensor on the watch body can identify whether the first watch strap is installed on the watch body or the second watch strap is installed on the watch body by detecting the first magnetism or the second magnetic pole. It is understood that either the first or second watch strap can be installed on the watch body, that is, one watch body and one watch strap are matched. The user can choose to install either the first or second watch strap on the watch body as needed.

[0007] This application involves setting a Hall sensor in the main body of the watch and setting a magnet on the air bladder. The magnets on the air bladders of different types of watch straps face different magnetic poles of the Hall sensor. Thus, the Hall sensor can identify the type of watch strap installed in the main body by detecting the type of magnetic pole. Users can know whether they are wearing the wrong watch strap based on the identification result, avoiding the problem of decreased blood pressure accuracy caused by using the wrong watch strap.

[0008] In one possible implementation, the first watch band is suitable for users with wrist circumferences ranging from 130mm to 160mm (inclusive), and the second watch band is suitable for users with wrist circumferences ranging from 161mm to 230mm (inclusive). Users with different wrist circumferences can choose watch bands with different airbag lengths as needed. This ensures that the airbags in the watch bands can fully cover the radial and ulnar arteries while also preventing the watch bands from becoming excessively long, thus guaranteeing a good user experience.

[0009] In one possible implementation, the first magnetic pole is the S pole and the second magnetic pole is the N pole.

[0010] In one possible implementation, the first magnetic pole is the N pole and the second magnetic pole is the S pole.

[0011] In one possible implementation, the first magnet is located in the first airbag near the main body of the watch.

[0012] In one possible implementation, the second magnet is located in the second airbag near the main body of the watch.

[0013] In one possible implementation, the second magnet is disposed on the cover plate of the second watch strap, and the cover plate is used to connect to the watch body.

[0014] In one possible implementation, the second strap includes a first strap body and a second strap body, which are respectively connected to the two sides of the watch body, and the second airbag is disposed inside the first strap body.

[0015] In one possible implementation, the second watch strap includes a first strap body and a second strap body, which are respectively connected to the two sides of the watch body, and the second airbag is disposed inside the first strap body and the watch body.

[0016] In one possible implementation, the second watch strap includes a first strap body and a second strap body, which are respectively connected to both sides of the watch body, and the second airbag is disposed inside the first strap body, the watch body, and the second strap body.

[0052] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0053] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a first embodiment of an electronic device provided in this application; Figure 2 yes Figure 1 A schematic diagram of the electronic device from another angle. Wherein, Figure 1 This is a front view of the electronic device. Figure 2 This is a schematic diagram of the rear structure of an electronic device.

[0054] Electronic devices 100 include, but are not limited to, wrist-worn electronic products such as watches, smartwatches, wristbands, and smart bracelets. Figure 1 The electronic device 100 of the illustrated embodiment is described using a smartwatch as an example.

[0055] The electronic device 100 includes a watch body 10 and a watch strap 20. The watch strap 20 is mounted on the watch body 10 and has an air bladder 50 installed inside the watch strap 20 and connected to the watch body 10. In this embodiment, the air bladder 50 is detachably connected to the watch strap 20 and the watch body 10 so that it can be removed from the watch strap 20 and the watch body 10 when blood pressure measurement is not being performed, making it more comfortable for daily wear. Of course, in other embodiments, the air bladder may also be detachably connected to the watch body 10 and fixedly connected to the watch strap. Alternatively, the air bladder may also be fixedly connected to the watch body and the watch strap.

[0056] The watch strap 20 comprises two straps, namely a first strap body 21 and a second strap body 22, which are respectively connected to opposite sides of the watch body 10. In this embodiment, both the first strap body 21 and the second strap body 22 are detachably connected to opposite sides of the watch body 10. This facilitates the replacement of different types of straps with the watch body 10, meeting various wearing requirements of the user and improving the user experience. Of course, in other embodiments, the first strap body 21 and the second strap body 22 can also be fixedly connected to opposite sides of the watch body 10.

[0057] For example, the first strap 21 has a mounting portion and a first locking portion (not shown), and the second strap 22 has a mounting portion and a second locking portion (not shown). The mounting portions of the first strap 21 and the second strap 22 are respectively mounted on opposite sides of the watch body 10. The first locking portion and the second locking portion are detachably locked to each other to wear the electronic device 100 on the user's wrist. It should be understood that the mating structure between the first locking portion and the second locking portion can be a hook clasp, concealed clasp, butterfly clasp, leather strap snap, folding safety clasp, folding clasp, or pin buckle, etc., and this application does not limit this to any particular type of clasp.

[0058] Please see Figure 3 and Figure 4 , Figure 3 yes Figure 2 A schematic diagram of the main body of the electronic device shown; Figure 4 yes Figure 2 The diagram shows a cross-sectional view of the electronic device.

[0059] In this embodiment, the main body 10 of the meter has a cuboid structure and includes a housing 11, a display screen 12, a processor 13, and a blood pressure measuring component 14. The display screen 12 is connected to the housing 11 and together with the housing 11 forms a receiving space A of the main body 10. The processor 13 and the blood pressure measuring component 14 are both located within the receiving space A. The cuboid structure mentioned above includes both cuboid structures and structures approximating cuboid shapes. An approximating cuboid structure refers to a structure where the outer surface of the cuboid may have local concave lines or local convexities. The shape descriptions of the structures in the following text can be understood in the same way. It should be understood that in other embodiments, the main body 10 may also be a cylinder, a frustum of a cone, a cube, or other irregularly shaped structure.

[0060] The outer casing 11 includes a bottom wall 111 and a frame 112. The bottom wall 111 is fixed to one side of the frame 112, and the display screen 12 is fixed to the side of the frame 112 away from the bottom wall 111. That is, the bottom wall 111 and the display screen 12 are respectively fixed to opposite sides of the frame 112. The bottom wall 111, the frame 112, and the display screen 12 together enclose the receiving space A of the main body 10. When the user wears the electronic device 100, the display screen 12 is positioned away from the user's wrist, and the bottom wall 111 is positioned close to the user's wrist.

[0061] In this embodiment, the bottom wall 111 can be detachably mounted to the frame 112 to facilitate the repair and replacement of functional components such as the memory card, SIM card, and speaker inside the watch body 10. Of course, in other embodiments, the bottom wall 111 and the frame 112 can also be an integrally formed structure to improve the stability of the watch body 10.

[0062] The frame includes a first side and a second side that are set opposite to each other, and the mounting part of the first belt body 21 and the mounting part of the second belt body 22 are respectively detachably mounted on the first side and the second side.

[0063] The bottom wall 111 includes a top surface 1111 facing the receiving space A and a bottom surface 1112 opposite to the top surface 1111. The bottom surface 1112 is provided with a mounting groove 113 for mounting the airbag 50. In this embodiment, there is one mounting groove 113, which is located close to the first side. Of course, in other embodiments, the two opposite sides of the mounting groove 113 can be located close to the first side and the second side, respectively. Alternatively, the mounting groove 113 can also be located in other structures such as the frame 112.

[0064] The mounting slot 113 is provided with a connecting hole 114 that connects to the receiving space A. The connecting hole 114 penetrates the top surface 1111 and the slot wall of the mounting slot 113. The connecting hole 114 is used to enable communication between the airbag 50 and the components of the blood pressure measuring assembly 14 located in the receiving space A. In this embodiment, there is one connecting hole 114. Of course, in other embodiments, there may be one or more connecting holes. Alternatively, in other embodiments, the connecting hole is not provided in the mounting slot, and the connecting hole may be provided in the bottom wall 111 or other locations on the outer casing 11.

[0065] like Figure 4 and Figure 5 , Figure 5 yes Figure 2 The diagram shows the exploded structure of the electronic device.

[0066] In some embodiments, the electronic device 100 further includes a fixing member 15, which is fixed within the mounting groove 113 and located on the side of the airbag 50 facing away from the bottom wall 111. This fixing member secures the airbag 50, preventing it from detaching from the communication hole 114 and ensuring stable communication between the airbag 50 and the blood pressure measuring component 14 through the communication hole 114. The fixing member 15 also prevents the airbag 50 from detaching from the mounting groove 113, improving the installation stability between the airbag 50 and the bottom wall 111.

[0067] The display screen 12 includes a display panel and a cover plate fixed to the display panel. The cover plate can be made of lens materials such as glass. The display panel can be an LCD (Liquid Crystal Display), OLED (Organic Light-Emitting Diode) display, AMOLED (Active-Matrix Organic Light-Emitting Diode) display, FLED (Flexible Light-Emitting Diode) display, Mini LED, MicroLED, Micro OLED, QLED (Quantum Dot Light-Emitting Diodes), etc.

[0068] The display panel can also integrate touch functionality, meaning it's a touch-sensitive display panel that can function as both an input device for receiving input and an output device for providing input. In other words, the display screen 12 is a touchscreen. The display panel is electrically connected to the processor 13. The display panel generates touch signals and transmits them to the processor 13. The processor 13 receives the touch signals and controls the opening of the application software (App) in the main unit 10 based on these signals. For example, a user can select to open or edit a graphic by touching or pressing a graphic location on the display screen 12.

[0069] The processor 13 is housed within the housing space A. The processor 13 may include one or more processing units, such as an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, memory, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural network processing unit (NPU).

[0070] Different processing units can be independent devices or integrated into one or more processors 13. The processor 13 can serve as the nerve center and command center of the electronic device 100. The processor 13 can generate operation control signals based on the instruction opcode and timing signals to control instruction fetching and execution. Furthermore, the processor 13 may include a storage unit for storing instructions and data. For example, the storage unit of the processor 13 may be a cache memory. This memory can store instructions or data that the processor 13 has just used or is recurring. If the processor 13 needs to reuse the instruction or data, it can directly retrieve it from the memory, avoiding repeated access, reducing the processor 13's waiting time, and thus improving system efficiency.

[0071] like Figure 4The blood pressure measuring component 14 is electrically connected to the processor 13. In this embodiment, the blood pressure measuring component 14 includes an air pump 141 and a pressure sensor 142. The air pump 141 is electrically connected to the processor 13 and is used to receive control signals sent by the processor 13, and to draw in or expel gas according to the control signals. The pressure sensor 142 is spaced apart from the air pump 141 and electrically connected to the processor 13, and is used to receive control signals sent by the processor 13, and to sense pressure signals according to the control signals, converting the pressure signals into electrical signals. The pressure sensor 142 can be a capacitive pressure sensor. A capacitive pressure sensor includes at least two parallel plates with conductive material. When a force is applied to the pressure sensor 142, the capacitance between the electrodes changes. The processor 13 determines the pressure intensity based on the change in electrode capacitance. Of course, the pressure sensor 142 can also be a resistive pressure sensor or an inductive pressure sensor, etc.

[0072] Specifically, both the air pump 141 and the pressure sensor 142 are located in the receiving space A of the main body 10. The air pump 141 is connected to the connecting hole 114 to draw in or expel gas from the airbag 50 through the connecting hole 114. The pressure sensor 142 is positioned near the connection between the connecting hole 114 and the airbag 50 to facilitate the pressure sensor 142 in sensing changes in air pressure and measuring blood pressure.

[0073] In some embodiments, the main body 10 also includes a sensing component. The sensing component is spaced apart from the blood pressure measurement component 14 and electrically connected to the processor 13. Specifically, the bottom wall 111 includes a mounting hole penetrating the top surface 1111 and the bottom surface 1112. The sensing component includes a heart rate sensor, which faces the mounting hole (not shown) or is at least partially housed within it. The heart rate sensor is an optical heart rate sensor. When the user wears the electronic device 100, the bottom surface 1112 of the bottom wall 111 fits against the user's wrist, and the optical heart rate sensor can send a heart rate sensing signal through the mounting hole, achieving accurate heart rate detection, improving the functional versatility of the electronic device 100, and enhancing the user experience. Of course, the heart rate sensor can also be a bone conduction sensor or other sensor capable of heart rate detection.

[0074] In addition, the sensing components may also include sensors such as gyroscope sensors, barometric pressure sensors, accelerometers, distance sensors, proximity sensors, fingerprint sensors, temperature sensors, or ambient light sensors to further enhance the functionality of the electronic device 100 and improve the user experience.

[0075] like Figure 3In this embodiment, the watch body 10 may further include a Hall sensor 16, which is disposed in the watch body 10 and electrically connected to the processor 13. Specifically, the Hall sensor 16 may be disposed inside the receiving space A and opposite to the mounting slot 113, or it may be disposed within the mounting slot 113. The Hall sensor 16 is a device based on the Hall effect, capable of detecting changes in magnetic fields and outputting a voltage according to the measured magnetic field conditions to sense the type of the watch strap 20 mounted on the watch body 10.

[0076] Please see Figure 5 and Figure 6 , Figure 6 yes Figure 5 The diagram shows the structure of the first belt of the electronic device from another angle.

[0077] Understandably, the watch band 20 can come in various types to suit different user needs. For example, depending on the application requirements of different scenarios, the watch band 20 needs to have an air bladder when the user is measuring blood pressure, while the watch band 20 without an air bladder is more comfortable to wear when blood pressure measurement is not required. Alternatively, depending on the application needs of different users, the blood pressure measurement can be suitable for the user to measure blood pressure, or it can be suitable for the user's family members to measure blood pressure.

[0078] In this embodiment, there are two types of watch straps 20: a first watch strap and a second watch strap. The first watch strap has a first airbag, and the second watch strap has a second airbag. The first and second airbags have different lengths. It is understood that the length of the first watch strap is adapted to the length of the first airbag, and the length of the second watch strap is adapted to the length of the second airbag. It is also understood that either the first or second watch strap is installed on the watch body 10; that is, one watch body and one watch strap are matched. The user can choose to install either the first or second watch strap on the watch body as needed.

[0079] It is understandable that obtaining accurate blood pressure values ​​requires the air bladder of the watch strap 20 to fully cover the radial and ulnar arteries. However, existing watch straps are designed to be relatively long to accommodate users with different wrist sizes. For users with smaller wrists, an excessively long strap may inevitably get caught in the bottom of the watch body, affecting the user experience. Therefore, this embodiment offers two types of watch straps 20, each with a different air bladder length. Users with different wrist sizes can choose watch straps 20 with different air bladder lengths as needed. This ensures that the air bladder of the watch strap 20 fully covers the radial and ulnar arteries while also preventing the watch strap from becoming excessively long, thus guaranteeing a better user experience.

[0080] In this embodiment, the way the first airbag engages with the first watch band and the way the second airbag engages with the second watch band are the same. The following description uses the engagement of the first airbag with the first watch band as an example. The first airbag is located inside the first band body 21 and installed in the mounting groove 113. Of course, in other embodiments, the first airbag may also be located inside the second band body. Alternatively, the first airbag may also be located inside the watch body and the first band body. Alternatively, the first airbag may also be located inside the first watch body, the watch body, and the second band body.

[0081] In this embodiment, the specific structures of the first airbag and the second airbag are the same, except for their lengths. The following description will use the first airbag as an example. Figure 5 and Figure 6 The first airbag 50a includes a mounting portion 51. When the first airbag 50a is installed in the corresponding mounting groove 113, the mounting portion 51 of the first airbag 50a is installed in the mounting groove 113, and the fixing member 15 is located on the surface of the mounting portion 51 facing away from the mounting groove 113, so as to install the first airbag 50a on the main body 10. The mounting portion 51 is provided with an air nozzle 52. When the first airbag 50a is installed in the corresponding mounting groove 113, the air nozzle 52 is inserted into the communication hole 114 of the housing to realize the communication between the first airbag 50a and the air pump 141, so that the air pump 141 can draw gas from or expel gas from the first airbag 50a.

[0082] Of course, in other embodiments, the first airbag and the second airbag may have the same length but different widths. Alternatively, the first airbag and the second airbag may have different lengths and widths. Or, the first airbag and the second airbag may have different volumes, that is, the first airbag and the second airbag may have different inflation volumes.

[0083] Please refer to the following: Figure 4 and Figure 6 In some embodiments, the outer periphery of the air nozzle 52 is provided with a groove, and the sealing ring 53 is disposed in the groove to seal the gap between the air nozzle 52 and the wall of the connecting hole 114, ensuring that the first airbag 50a does not leak. Of course, in other embodiments, the air nozzle 52 and the connecting hole 114 can also be sealed by other structures besides the sealing ring 53.

[0084] It is understandable that the way the second airbag is installed in the mounting slot 113 corresponding to the main body 10 can be the same as or different from that of the first airbag 50a, which will not be elaborated further.

[0085] When the user wears the electronic device 100 on their wrist, the first airbag 50a fits snugly against the user's wrist. When the electronic device 100 receives a blood pressure measurement command, the processor 13 sends a blood pressure measurement signal to the air pump 141 and the pressure sensor 142. The air pump 141 inflates and pressurizes the first airbag 50a through the connecting hole 114 and the air nozzle 52. At this time, the first airbag 50a inflates and compresses the user's radial and ulnar arteries. The pressure sensor 142 detects the air pressure value inside the first airbag 50a and feeds it back to the processor 13 in real time. The processor 13 determines whether the air pressure value inside the first airbag 50a meets the requirements for blood pressure measurement. If not, it continues to send a blood pressure measurement signal to the air pump 141, which continues to inflate and pressurize the first airbag 50a until the processor 13 determines that the air pressure value fed back by the pressure sensor 142 meets the requirements for blood pressure measurement. The processor 13 calculates the user's blood pressure based on the real-time air pressure value fed back by the pressure sensor 142 and displays it to the user on the display screen 12. After the blood pressure measurement is completed, the processor 13 stops sending the blood pressure measurement signal, the air pump 141 and the pressure sensor 142 both stop working, the gas in the first airbag 50a is transferred to the air pump 141 and discharged by the air pump 141, at which time the first airbag 50a returns to flat and fits against the user's wrist.

[0086] For example, in this embodiment, such as Figure 7 The length of the first airbag 50a is less than the length of the second airbag 50b. Correspondingly, the length of the first strap body of the first watchband is less than the length of the first strap body of the second watchband. When the watchband 20 is the first watchband, it is a short airbag watchband; when the watchband 20 is the second watchband, it is a long airbag watchband. The first watchband is suitable for users with smaller wrist circumferences, and the second watchband is suitable for users with larger wrist circumferences. For example, the first watchband can be suitable for users with wrist circumferences in the range of 130mm to 160mm (inclusive), and the second watchband can be suitable for users with wrist circumferences in the range of 161mm to 230mm (inclusive). It is understood that the lengths of the second strap body 22 of the first and second watchbands can be the same or different.

[0087] In this embodiment, as Figure 5A magnet can also be provided on the watch strap 20. Specifically, the magnet is provided in the mounting part of the airbag 50. When the airbag 50 is installed in the mounting groove 113, the magnet and the Hall sensor 16 are positioned opposite each other. For example, it can be understood that the magnet provided on the first watch strap is the first magnet 54, and the magnet provided on the second watch strap is the second magnet. When the watch strap 20 is the first watch strap, the first magnetic pole of the first magnet 54 provided on the first airbag 50a faces the Hall sensor 16. When the watch strap 20 is the second watch strap, the second magnetic pole of the second magnet provided on the second airbag faces the Hall sensor 16. The first magnetic pole and the second magnetic pole are different. In this embodiment, the first magnetic pole is the S pole, and the second magnetic pole is the N pole. Of course, in other embodiments, the first magnetic pole can also be the N pole, and the second magnetic pole can also be the S pole.

[0088] Of course, in other embodiments, the first magnet may also be disposed in the mounting portion of the first watch strap, and the second magnet may be disposed in the mounting portion of the second watch strap.

[0089] When the first watch band 21 is installed on the watch body 10, if the Hall sensor 16 detects the magnetic field of the first magnetic pole, the processor 13 determines that the first watch band is installed on the watch body 10. If the Hall sensor 16 detects the magnetic field of the second magnetic pole, the processor 13 determines that the second watch band is installed on the watch body 10. The processor 13 can send the detection results to the display screen 12. Figure 3 This information is presented to the user, allowing them to determine whether they are wearing the wrong watchband based on the test results, thus preventing a decrease in blood pressure accuracy caused by using the wrong watchband.

[0090] In this embodiment, a Hall sensor 16 is set on the main body 10 of the watch and a magnet is set on the air bladder 50. The magnets on the air bladder 50 of different types of watch straps 20 face the Hall sensor 16 with different magnetic poles. Thus, the Hall sensor 16 can identify the type of watch strap 20 installed on the main body 10 by detecting the type of magnetic pole. The user can know whether he / she is wearing the wrong watch strap according to the identification result, avoiding the problem of decreased blood pressure accuracy caused by the user using the wrong watch strap.

[0091] It is understandable that, such as Figure 8The Hall sensor 16 includes a first output pin 161 and a second output pin 162. The Hall sensor 16 can detect changes in magnetic fields, including a north pole magnetic field, a south pole magnetic field, and no magnetic field. When the watch band 20 is installed on the watch body 10, if the watch band 20 is the first watch band and the south pole of the first airbag 50a faces the Hall sensor 16, then the level detection of the first output pin 161 of the Hall sensor 16 is low, and the level detection of the second output pin 162 is high. If the watch band 20 is the second watch band and the north pole of the second airbag faces the Hall sensor 16, then the level detection of the first output pin 161 of the Hall sensor 16 is high, and the level detection of the second output pin 162 is low.

[0092] In this embodiment, the Hall sensor 16 can also detect the absence of a magnetic field. When the airbag 50 is not installed on the main body 10, the level detection of the first output pin 161 and the second output pin 162 of the Hall sensor 16 is both low. It is understandable that when the Hall sensor 16 detects no magnetic field, it may also be due to the airbag 50 being loosely installed. When the user receives a message from the electronic device 100 indicating that the main body 10 is not equipped with the airbag 50, they can install the airbag 50 on the main body 10 or check whether the airbag 50 has become loose, thus preventing water damage to the device caused by the user washing hands or taking a shower when the airbag 50 has become loose.

[0093] Of course, in some other embodiments, the electronic device 100 may identify the type of watch strap 20 without using a Hall sensor and a magnet. That is, the electronic device 100 may not include a Hall sensor and a magnet. The processor 13 can also control the air pump 141 to inflate the watch strap 20, obtain test data, and determine whether the watch strap 20 is the first watch strap or the second watch strap based on the test data. Specifically, the air pump 141 inside the watch body 10 can inflate the air bladder 50. Since the lengths of the air bladders of the first and second watch straps are different, the pressure changes detected by the pressure sensor 142 are also different when inflating the air bladders of the first and second watch straps. The slopes of the pressure curves of the first and second watch straps in the inflated state are different. The slope of the pressure curve is the test data. By determining the slope of the pressure curve of the watch strap 20 in the inflated state, it is determined whether the watch strap 20 is the first watch strap or the second watch strap.

[0094] The second embodiment of the electronic device 100 of this application is described below. The electronic device 100 of this embodiment has a generally similar structure to the electronic device 100 of the first embodiment; the structurally identical parts can be referred to in the accompanying drawings of the first embodiment. The difference is that the watch strap 20 in this embodiment has three types: a short airbag watch strap, a long airbag watch strap, and a regular watch strap. Both the short airbag watch strap and the long airbag watch strap have airbags, while the regular watch strap does not. The short airbag watch strap has a first airbag, and the long airbag watch strap has a second airbag; the lengths of the first and second airbags are different. The regular watch strap includes a cover plate. Specifically, the short airbag watch strap is the first watch strap, and the long airbag watch strap and the regular watch strap are the second watch straps. Of course, in other embodiments, the long airbag watch strap can be the first watch strap, and the short airbag watch strap and the regular watch strap can be the second watch strap.

[0095] Understandably, obtaining accurate blood pressure readings requires the air bladder in the watch band to fully cover the radial and ulnar arteries. However, existing watch bands are designed to be relatively long to accommodate users with varying wrist sizes. For users with smaller wrists, the excessively long band may get caught on the bottom of the watch body, affecting the user experience. Furthermore, electronic devices have other functions besides blood pressure measurement, such as time display. When used in scenarios where blood pressure measurement is not required, the comfort of wearing a watch band with an air bladder is compromised.

[0096] Therefore, this embodiment offers three types of watch straps 20: a long airbag strap, a short airbag strap, and a regular strap. When measuring blood pressure, users with different wrist circumferences can choose watch straps 20 with different airbag lengths as needed. This ensures that the airbag of the strap 20 can fully cover the radial and ulnar arteries while preventing the strap from becoming excessively long, thus guaranteeing a good user experience. When not measuring blood pressure, users can choose a regular strap to improve wearing comfort.

[0097] In this embodiment, the way the first airbag and the short airbag strap are connected, and the way the second airbag and the long airbag strap are connected, can be referred to the way the first airbag and the first strap are connected in the first embodiment, and will not be repeated here. It is understood that, since the first airbag can be detachably connected to the first strap body and the watch body of the short airbag strap, and the second airbag can be detachably connected to the first strap body and the watch body of the long airbag strap, the following description uses the short airbag strap as an example.

[0098] like Figure 9After the first airbag is detached from the first strap body of the short airbag watchband and from the mounting groove of the watch body, a cover plate 60 covers the mounting groove 113. The cover plate 60 includes an air nozzle located at a vent hole in the mounting groove 113 to seal the vent hole, thereby turning the short airbag watchband into a regular watchband. Similarly, the long airbag watchband can also become a regular watchband by removing the second airbag. Of course, in other embodiments, the short airbag watchband can also become a regular watchband simply by removing the first airbag.

[0099] The length of the first airbag is shorter than the length of the second airbag; correspondingly, the length of the first band of the short airbag watchband is shorter than the length of the first band of the long airbag watchband. The short airbag watchband is suitable for users with smaller wrist circumferences, while the long airbag watchband is suitable for users with larger wrist circumferences. When the watchband 20 is a standard watchband, the cover plate 60 covers the mounting slot. For example, the short airbag watchband can be suitable for users with wrist circumferences in the range of 130mm to 160mm (inclusive), and the long airbag watchband can be suitable for users with wrist circumferences in the range of 161mm to 230mm (inclusive). It is understood that the lengths of the second band 22 of the short and long airbag watchbands can be the same or different. The standard watchband is suitable for scenarios where the user does not measure blood pressure.

[0100] In this embodiment, a magnet may also be provided on the watch strap 20. Specifically, the magnet is provided in the airbag mounting portion 51, and when the airbag is installed in the mounting groove 113, the magnet and the Hall sensor 16 are positioned opposite each other. It can be understood that the magnet on the first watch strap is the first magnet 54, and the magnet on the second watch strap is the second magnet. For example, when the watch strap 20 is a short airbag watch strap, the first magnetic pole of the first magnet 54 on the first airbag 50a faces the Hall sensor 16. When the watch strap 20 is a second watch strap (a long airbag watch strap or a regular watch strap), the second magnet on the second airbag or the second magnetic pole on the cover plate faces the Hall sensor 16. The first and second magnetic poles are different. In this embodiment, the first magnetic pole is the S pole, and the second magnetic pole is the N pole. Of course, in other embodiments, the first magnetic pole may also be the N pole, and the second magnetic pole may also be the S pole.

[0101] Of course, in other embodiments, the first magnet may also be disposed in the mounting part of the first watch strap, and when the watch strap is a long airbag watch strap, the second magnet may be disposed in the mounting part of the second watch strap.

[0102] When the first strap 21 is installed on the main body 10 of the watch, if the Hall sensor 16 detects the magnetic field of the first magnetic pole, the processor 13 determines that the strap 20 is a short airbag strap. If the Hall sensor 16 detects the magnetic field of the second magnetic pole, the processor 13 determines that the strap 20 is a second strap. Then, the processor 13 drives the air pump to inflate the second strap and obtain test data; then, the test data is compared with preset data to determine the type of test data. If the test data is the first data, the second strap is a long airbag strap; if the test data is the second data, the second strap is a regular strap. The processor 13 can send the detected results to the display screen 12 to present to the user. The user can know whether they are wearing the wrong strap based on the detection results, avoiding the problem of decreased blood pressure accuracy caused by the user using the wrong strap.

[0103] Understandably, the air pump 141 inside the watch body 10 can inflate the second watch band. Since the long airbag watch band has an airbag while the ordinary watch band does not, the pressure sensor 142 detects different pressure changes when the long airbag watch band and the ordinary watch band are inflated. Because the ordinary watch band does not have an airbag and cannot store gas, the pressure curve slope of the ordinary watch band will rise rapidly at a fixed slope in a short period of time. However, because the long airbag watch band has an airbag, the pressure curve slope of the long airbag watch band will rise slowly at a fixed slope over a period of time.

[0104] The pressure curves of the long-airbag watchband and the regular watchband differ when inflated. These pressure curve slopes are the test data. By comparing the pressure curve slope of the second watchband with predetermined data (the pressure curve slopes of the long-airbag watchband and the regular watchband), if the pressure curve slope of the second watchband matches that of the long-airbag watchband, then the test data is the first data, and the second watchband is the long-airbag watchband. If the pressure curve slope of the second watchband matches that of the regular watchband, then the test data is the second data, and the second watchband is the regular watchband.

[0105] In this embodiment, a Hall sensor 16 is installed on the main body 10 of the watch, and a magnet is installed on the air bladder or cover plate. The magnets on the air bladder or cover plate of the first and second watch straps face different magnetic poles towards the Hall sensor 16. Thus, the Hall sensor 16 can identify whether the watch strap 20 installed on the main body 10 is the first watch strap or the second watch strap by detecting the type of magnetic poles. If the watch strap 20 is the first watch strap, it can be determined that the watch strap 20 is a short air bladder watch strap. If the watch strap 20 is the second watch strap, it is further inflated to identify whether the second watch strap is a long air bladder watch strap or a regular watch strap. The processor 13 presents the identification results to the user through the display screen 12. The user can know whether they are wearing the wrong watch strap based on the identification results, avoiding the problem of decreased blood pressure accuracy caused by the user using the wrong watch strap.

[0106] In this embodiment, if the Hall sensor 16 detects no magnetic field, it may be due to the airbag 50 or the cover being loose. If the user receives a message from the electronic device 100 indicating that the main body 10 of the meter is not equipped with the airbag 50 or the cover, the user can install the airbag 50 or the cover onto the main body 10 of the meter or check whether the airbag 50 or the cover has become loose, thus preventing water damage to the device caused by the user washing hands or taking a shower when the airbag 50 has become loose.

[0107] Of course, in other embodiments, while the Hall sensor 16 identifies the magnetic poles of the watch strap 20, the air pump 141 inside the watch body 10 can inflate the watch strap 20 to confirm in a short time whether the watch strap 20 is a normal watch strap. Thus, the processor 13 can quickly determine the type of watch strap 20 in a short time based on the combined results of the Hall sensor 16 and the magnetic poles and the way the watch strap 20 is inflated.

[0108] Of course, in other embodiments, the electronic device 100 can also directly identify whether the watch strap 20 is a short airbag strap, a long airbag strap, or a regular strap by inflating the strap 20. Using this identification method, the electronic device 100 does not need to use the Hall sensor 16 and the magnet, which reduces the number of components in the electronic device 100, lowers costs, and increases the integration of the electronic device 100. However, identifying the watch strap 20 by inflating it takes longer than first identifying the first and second straps using the Hall sensor 16 and the magnet, and then further identifying the long airbag strap and the regular strap by inflating the strap 20; the user experience is not as good as the latter.

[0109] The third embodiment of the electronic device 100 of this application is described below. The electronic device 100 of this embodiment has a generally similar structure to the electronic device 100 of the second embodiment; the structurally identical parts can be referred to in the accompanying drawings of the second embodiment. The differences are as follows: Figure 10 The electronic device 100 also includes an acquisition module 30 and a comparison module 40, both of which are electrically connected to the processor 13. Of course, in some embodiments, the acquisition module 30 and the comparison module 40 may also be part of the processor 13.

[0110] The acquisition module 30 is used to acquire the user's wrist circumference data. For example, the watch body may include buttons, and the electronic device's display screen or buttons are used to receive user input. The acquisition module 30 acquires the electrical signals from the display screen or buttons to obtain the wrist circumference data input by the user. The comparison module 40 compares the wrist circumference data with the type of the watch strap 20 to determine whether the watch strap 20 is correctly or incorrectly selected. If the watch strap 20 is incorrectly selected, the processor 13 reminds the user to change to the correct watch strap 20. If the watch strap 20 is correctly selected, the blood volume measurement step is initiated. Of course, in other embodiments, the acquisition module 30 can also automatically measure and obtain the user's wrist circumference data.

[0111] This implementation identifies the type of watch strap 20 and compares it with the user's wrist circumference data to determine whether the user has selected the correct or incorrect watch strap 20. If the correct watch strap 20 is selected, the blood volume measurement step proceeds. If the incorrect watch strap 20 is selected, the user is reminded to replace it with the correct one, thus preventing the user from selecting the wrong watch strap 20 and making blood pressure measurement more accurate.

[0112] In some other embodiments, please refer to Figure 11 , Figure 11 yes Figure 2 A schematic diagram of another embodiment of the electronic device shown.

[0113] This embodiment and Figure 2 The structures of the illustrated embodiments are largely the same, and the identical parts will not be described again. The difference lies in the type of watch strap 20: a short airbag strap, a long airbag strap, and a regular strap. Both the short and long airbag straps have airbags, while the regular strap does not. The short airbag strap has a first airbag, and the long airbag strap has a second airbag. The lengths of the first and second airbags are different. The regular strap includes a cover plate. The short airbag strap is the first strap, and the long airbag strap and the regular strap are the second straps.

[0114] In this embodiment, the airbag 50 is disposed inside the first strap body, the main body of the watch, and the second strap body. When the watch strap 20 is a short airbag watch strap, the first airbag is disposed inside the first strap body, the main body of the watch, and the second strap body. When the watch strap 20 is a long airbag watch strap, the second airbag is disposed inside the first strap body, the main body of the watch, and the second strap body. When the watch strap 20 is a regular watch strap, the cover plate is disposed inside the main body of the watch.

[0115] The first airbag is shorter than the second airbag, and the shorter airbag strap is shorter than the longer airbag strap. The shorter airbag strap is suitable for users with smaller wrists, while the longer airbag strap is suitable for users with larger wrists. For example, the shorter airbag strap is suitable for users with wrists ranging from 130mm to 160mm (inclusive), while the longer airbag strap is suitable for users with wrists ranging from 161mm to 230mm (inclusive). The standard airbag is suitable for scenarios where blood pressure measurement is not required.

[0116] In this embodiment, the air nozzle of the airbag 50 can be located on the part of the airbag close to the main body of the watch. This application does not impose any limitations on this.

[0117] In some other embodiments, please refer to Figure 12 , Figure 12 yes Figure 2 A schematic diagram of another embodiment of the electronic device shown.

[0118] This embodiment and Figure 11 The structures of the illustrated embodiments are largely the same, and the identical parts will not be described again. The difference lies in the type of watch strap 20: a short airbag strap, a long airbag strap, and a regular strap. Both the short and long airbag straps have airbags, while the regular strap does not. The short airbag strap has a first airbag, and the long airbag strap has a second airbag. The lengths of the first and second airbags are different. The regular strap includes a cover plate. Specifically, the short airbag strap is the first strap, and the long airbag strap and the regular strap are the second straps. In this embodiment, the airbag 50 is located inside the first strap body and the watch body. When the strap 20 is a short airbag strap, the first airbag is located inside the first strap body and the watch body; when the strap 20 is a long airbag strap, the second airbag is located inside the first strap body and the watch body; and when the strap 20 is a regular strap, the cover plate is located on the watch body.

[0119] The first airbag is shorter than the second airbag, and the shorter airbag strap is shorter than the longer airbag strap. The shorter airbag strap is suitable for users with smaller wrists, while the longer airbag strap is suitable for users with larger wrists. For example, the shorter airbag strap is suitable for users with wrists ranging from 130mm to 160mm (inclusive), while the longer airbag strap is suitable for users with wrists ranging from 161mm to 230mm (inclusive). The standard airbag is suitable for scenarios where blood pressure measurement is not required.

[0120] In this embodiment, the air nozzle of the airbag 50 can be located on the part of the airbag close to the main body of the watch. This application does not impose any limitations on this.

[0121] The structure of an electronic device 100 has been described in detail above. The following section will describe a method for identifying the watch strap 20 of the electronic device 100, based on the structure of the first embodiment of the electronic device 100 described above.

[0122] Please see Figure 13 , Figure 13 This is a flowchart illustrating the watchband 20 identification method of the electronic device 100 in the first embodiment. The watchband 20 identification method of the electronic device 100 includes the following steps S110 to S130:

[0123] S110: Obtain the magnetic poles of the watch strap 20.

[0124] Specifically, such as Figure 5 and Figure 14 The electronic device 100 includes a table body 10 ( Figure 1The watch strap 20 has an air bladder 50 on its inner side. In this embodiment, the watch strap 20 has two types: a first watch strap and a second watch strap. The first watch strap has a first air bladder, and the second watch strap has a second air bladder. The first air bladder and the second air bladder have different lengths, so that the user can choose a suitable watch strap 20 according to their wrist circumference.

[0125] The watch body 10 is equipped with a Hall sensor 16, and the air bladder 50 of the watch strap 20 is equipped with a magnet. The magnets are positioned differently in the air bladders of the first and second watch straps. When the watch strap 20 is the first watch strap, it is mounted on the watch body 10, and the first pole of the first magnet is positioned opposite the Hall sensor 16 of the watch body 10. When the watch strap 20 is the second watch strap, it is mounted on the watch body 10, and the second pole of the second magnet is positioned opposite the Hall sensor 16 of the watch body 10. The first and second poles are different. Specifically, the first pole is the S pole, and the second pole is the N pole. Since the Hall sensor 16 can detect changes in the magnetic field, and the magnetic poles of different watch straps 20 are different, the watch body 10 can identify whether the watch strap 20 is the first or second watch strap by recognizing the magnetic poles.

[0126] Before acquiring the magnetic poles of the watchband 20, the process also includes receiving a watchband 20 identification command. It is understood that when the processor 13 detects certain user actions, it can send a watchband 20 identification command to the Hall sensor 16. For example, when the processor 13 detects that the user is turning on the electronic device 100 for the first time, when the processor 13 detects that the user is opening the blood pressure measurement function page of the electronic device 100, or when the processor 13 detects that the user is attaching the watchband 20 to the watch body 10. After receiving the watchband 20 identification command, the Hall sensor 16 detects the magnetic poles of the watchband 20 to acquire them.

[0127] S120: Determine whether the watch strap 20 is the first watch strap or the second watch strap based on the magnetic poles of the watch strap 20.

[0128] Specifically, such as Figure 19 If the Hall sensor detects the magnetic field of the first magnetic pole, then the watch strap 20 becomes the first watch strap; if the Hall sensor detects the magnetic field of the second magnetic pole, then the watch strap 20 becomes the second watch strap. The first watch strap is a short airbag strap, and the second watch strap is a long airbag strap. The first watch strap is suitable for users with smaller wrist circumferences, and the second watch strap is suitable for users with larger wrist circumferences. For example, the first watch strap can be used for users with wrist circumferences in the range of 130mm to 160mm (inclusive), and the second watch strap can be used for users with wrist circumferences in the range of 161mm to 230mm (inclusive).

[0129] Of course, if the magnetic poles of the watch strap 20 are non-magnetic, then the airbag is not installed on the watch body 10, or the airbag is detached from the watch body 10.

[0130] S130: Send the type of watchband 20 to the user interface.

[0131] Specifically, when step S120 determines that watch strap 20 is the first watch strap, such as... Figure 15 The system sends a message to the user interface stating, "The current watch band is a short airbag band. Please confirm that the band is correct." If the user confirms that the type of watch band 20 is correct, they click "Yes"; otherwise, they click "No." In some embodiments, along with the message "The current watch band is a short airbag band. Please confirm that the band is correct," a note is added below it stating, "The short airbag band is suitable for users with a wrist circumference of 130mm to 160mm."

[0132] When step S120 determines that watch strap 20 is the second watch strap, such as Figure 16 The system sends a message to the user interface stating, "The current watch band is a long airbag band. Please confirm that the band is correct." If the user confirms that the type of watch band 20 is correct, they click "Yes"; otherwise, they click "No." In some embodiments, along with the message "The current watch band is a long airbag band. Please confirm that the band is correct," a note is added below it stating, "The long airbag band is suitable for users with wrist circumferences between 161mm and 230mm."

[0133] When step S120 determines that the watch body 10 is not fitted with the watch strap 20 or the watch strap 20 is loose, such as Figure 17 The system sends a message to the user interface stating, "The watchband is currently not installed or is loose. Please install or adjust the watchband." In some implementations, a note is added below the above text: "The short airbag watchband is suitable for users with a wrist circumference of 130mm to 160mm, and the long airbag watchband is suitable for users with a wrist circumference of 161mm and 230mm. Please select the appropriate watchband to install."

[0134] This embodiment identifies the type of watch strap 20 installed on the watch body 10 and sends the identification result to the user interface. The user can then determine whether they are wearing the wrong strap, preventing a decrease in blood pressure accuracy due to using the wrong strap. Furthermore, if the user receives a message from the electronic device 100 indicating that the watch body 10 is not equipped with the watch strap 20, they can either install the strap 20 or check if it has become loose, preventing water damage to the device caused by washing hands or showering when the strap is loose.

[0135] Of course, in other embodiments, the electronic device 100 can also identify the type of watchband 20 without using the Hall sensor 16 and the magnet. For example, it can identify the type of watchband 20 by inflating it. Specifically, after receiving the watchband 20 identification command, the processor 13 controls the air pump 141 to inflate the watchband 20, and the pressure sensor 142 acquires the air pressure change value to obtain the slope of the pressurization curve of the watchband 20 in the inflated state. It is understood that the airbag lengths of long airbag watchbands and short airbag watchbands are different, so the slopes of their pressurization curves are different. The slopes of their pressurization curves can be stored in the processor 13 in advance. By comparing the obtained pressurization curve slope with the pre-stored pressurization curve slope, it can be determined whether the watchband 20 is a long airbag watchband or a short airbag watchband.

[0136] Please see Figure 18 , Figure 18 This is a flowchart illustrating the watchband 20 identification method of the electronic device 100 in the second embodiment. The watchband 20 identification method of the electronic device 100 includes the following steps S210 to S240:

[0137] S210: Obtain the magnetic poles of the watch strap 20.

[0138] For details, please refer to Figure 5 and Figure 19 The electronic device 100 includes a table body 10 ( Figure 1 The watch strap 20 has an airbag 50 on its inner side. In this embodiment, the watch strap 20 has three types: a short airbag strap, a long airbag strap, and a regular strap. Both the short airbag strap and the long airbag strap have airbags, while the regular strap does not. The short airbag strap has a first airbag, the long airbag strap has a second airbag, and the first and second airbags have different lengths. The regular strap includes a cover plate. The short airbag strap is the first strap, and the long airbag strap and the regular strap are the second straps.

[0139] When measuring blood pressure, users with different wrist circumferences can choose watch straps 20 with different airbag lengths as needed. This ensures that the airbags in watch strap 20 can fully cover the radial and ulnar arteries while also preventing the watch strap from becoming excessively long, thus guaranteeing a good user experience. When not measuring blood pressure, users can choose a regular watch strap for improved wearing comfort.

[0140] The watch body 10 is equipped with a Hall sensor 16, and the air bladder 50 or cover plate of the watch strap 20 is equipped with a magnet. The first and second watch straps have different ways of setting the magnets in their air bladders or covers. When the watch strap 20 is the first watch strap, it is mounted on the watch body 10, and the first magnetic pole of the first magnet is positioned opposite the Hall sensor 16 on the watch body 10. When the watch strap 20 is the second watch strap, it is mounted on the watch body 10, and the second magnetic pole of the second magnet is positioned opposite the Hall sensor 16 on the watch body 10. The first and second magnetic poles are different. Specifically, the first magnetic pole is the S pole, and the second magnetic pole is the N pole. Since the Hall sensor 16 can detect changes in the magnetic field, and the magnetic poles of different watch straps 20 are different, the watch body 10 can identify whether the watch strap 20 is the first or second watch strap by recognizing the magnetic poles.

[0141] Before acquiring the magnetic poles of the watchband 20, the process also includes receiving a watchband 20 identification command. It is understood that when the processor 13 detects certain user actions, it can send a watchband 20 identification command to the Hall sensor 16. For example, when the processor 13 detects that the user is turning on the electronic device 100 for the first time, when the processor 13 detects that the user is opening the blood pressure measurement function page of the electronic device 100, or when the processor 13 detects that the user is attaching the watchband 20 to the watch body 10. After receiving the watchband 20 identification command, the Hall sensor 16 detects the magnetic poles of the watchband 20 to acquire them.

[0142] S220: Confirm that the watch strap 20 is the first watch strap or the second watch strap based on the magnetic poles of the watch strap 20.

[0143] Specifically, such as Figure 19 If the Hall sensor detects the magnetic field of the first magnetic pole, then the strap 20 is the first strap, that is, the strap 20 is the short airbag strap; if the Hall sensor detects the magnetic field of the second magnetic pole, then the strap 20 is the second strap. The first strap is suitable for users with smaller wrist circumferences to measure blood pressure. For example, the first strap can be used for users with wrist circumferences in the range of 130mm to 160mm (inclusive).

[0144] Of course, if the magnetic poles of the watch strap 20 are non-magnetic, then the airbag or cover is not installed on the watch body 10, or the airbag or cover is detached from the watch body 10.

[0145] S230: If the watch strap 20 is the second watch strap, then inflate the watch strap 20 and obtain the slope of the pressure curve of the watch strap 20.

[0146] Specifically, such as Figure 19If the watch strap 20 is the second watch strap, it indicates that the second watch strap is either a long airbag strap or a regular watch strap. It is understandable that the air pump 141 inside the watch body 10 can inflate the second watch strap. Since the long airbag strap has an airbag while the regular watch strap does not, the pressure sensor 142 will detect different pressure changes when the long airbag strap and the regular watch strap are inflated. Figure 20 Since ordinary watch straps do not have air bladders and cannot store gas, the pressure curve slope of ordinary watch straps will rise rapidly at a fixed slope (k1) in a short period of time. Long air bladder watch straps have air bladders, so the pressure curve slope of long air bladder watch straps will rise slowly at a fixed slope (k2) over a period of time.

[0147] The pressure curve slopes of the long-airbag watch strap and the regular watch strap differ when inflated. These pressure curve slopes are the test data. The test data for the second watch strap is compared with predetermined data (the pressure curve slopes of the long-airbag strap and the regular watch strap). If the pressure curve slope of the second watch strap matches that of the long-airbag strap, then the test data is the first data, and the second watch strap is the long-airbag strap. The second watch strap is suitable for users with larger wrist circumferences, for example, users with wrist circumferences ranging from 161mm to 230mm (inclusive). If the pressure curve slope of the second watch strap matches that of the regular watch strap, then the test data is the second data, and the second watch strap is the regular watch strap. The regular watch strap is suitable for users to wear when not measuring blood pressure, improving user comfort.

[0148] Of course, in other embodiments, while the Hall sensor 16 identifies the magnetic poles of the watch strap 20, the air pump 141 inside the watch body 10 can inflate the watch strap 20. That is, steps S220 and S230 can be performed simultaneously. This allows for quick confirmation of whether the watch strap 20 is a regular watch strap, so that the processor 13 can quickly determine the type of watch strap 20 based on the combined results of the Hall sensor 16's interaction with the magnetic poles and the inflation method of the watch strap 20.

[0149] S240: Send the type of watchband 20 to the user interface.

[0150] Specifically, when step S220 determines that watch strap 20 is the first watch strap, such as... Figure 15 The system sends a message to the user interface stating, "The current watch band is a short airbag band. Please confirm that the band is correct." If the user confirms that the type of watch band 20 is correct, they click "Yes"; otherwise, they click "No." In some embodiments, along with the message "The current watch band is a short airbag band. Please confirm that the band is correct," a note is added below it stating, "The short airbag band is suitable for users with a wrist circumference of 130mm to 160mm."

[0151] When step S230 determines that the watch strap 20 is a long airbag watch strap, such as Figure 16 The system sends a message to the user interface stating, "The current watch band is a long airbag band. Please confirm that the band is correct." If the user confirms that the type of watch band 20 is correct, they click "Yes"; otherwise, they click "No." In some embodiments, along with the message "The current watch band is a long airbag band. Please confirm that the band is correct," a note is added below it stating, "The long airbag band is suitable for users with wrist circumferences between 161mm and 230mm."

[0152] When step S230 determines that watch strap 20 is a standard watch strap, such as Figure 21 The system sends the message "The current watch band is a standard watch band. Please confirm that the watch band is correct" to the user interface. If the user confirms that the type of watch band 20 is correct, they click "Yes"; if the user confirms that the type of watch band 20 is incorrect, they click "No". In some embodiments, while sending "The current watch band is a standard watch band. Please confirm that the watch band is correct", a note is also added below this message: "Standard watch bands are suitable for scenarios where blood pressure is not measured."

[0153] When step S230 detects that the watch body 10 is not fitted with the watch strap 20 or the watch strap 20 is loose, the message "Watch strap not currently installed or watch strap loose detected. Please install or adjust the watch strap" is sent to the user interface. In some embodiments, below the above text, it is also noted that "Short airbag watch straps are suitable for users with wrist circumferences in the range of 130mm to 160mm, long airbag watch straps are suitable for users with wrist circumferences in the range of 161mm and 230mm, and ordinary watch straps are suitable for scenarios where blood pressure is not measured. Please select the appropriate watch strap to install."

[0154] This embodiment identifies the type of watch strap 20 installed on the watch body 10 and sends the identification result to the user interface. The user can then determine whether they are wearing the wrong strap, preventing a decrease in blood pressure accuracy due to using the wrong strap. Furthermore, if the user receives a message from the electronic device 100 indicating that the watch body 10 is not equipped with the watch strap 20, they can either install the strap 20 or check if it has become loose, preventing water damage to the device caused by washing hands or showering when the strap is loose.

[0155] Of course, in other embodiments, the electronic device 100 can also identify the type of watch strap 20 without the Hall sensor 16 and the first magnet 54 working together. For example, the type of watch strap 20 can be identified by inflating it. Specifically, after receiving the watch strap 20 identification command, the processor 13 controls the air pump 141 to inflate the watch strap 20, and the pressure sensor 142 acquires the air pressure change value to obtain the slope of the pressurization curve of the watch strap 20 in the inflated state. It is understood that the airbag lengths of long airbag watch straps and short airbag watch straps are different, and ordinary watch straps have no airbags. Therefore, the slopes of the pressurization curves of the three are different. The slopes of the pressurization curves of the three can be stored in the processor 13 in advance. By comparing the obtained pressurization curve slope with the pre-stored pressurization curve slope, it can be determined whether the watch strap 20 is a long airbag watch strap, a short airbag watch strap, or an ordinary watch strap.

[0156] Please see Figure 22 , Figure 22 This is a flowchart illustrating the watchband 20 identification method of the electronic device 100 in the third embodiment. The watchband 20 identification method of the electronic device 100 includes the following steps S310 to S350:

[0157] S310: Input the user's wrist circumference data.

[0158] Specifically, such as Figure 23 The user's wrist circumference data can be entered into the electronic device 100 when it is powered on. Specifically, the user can be guided through the setup process when the electronic device 100 is used for the first time. For example, ... Figure 24 A wrist circumference setting interface will pop up, prompting the user to "select the watchband scale range according to your measured wrist circumference." The user can choose "1~11 (130mm~160mm)" or "12~18 (161mm~230mm)" based on their wrist circumference, and then click "Next" after confirmation. Figure 24 When the user clicks "1~11 (130mm~160mm)", the interface displays "This range is suitable for short airbag straps" at the bottom. Figure 25 When the user clicks "12~18 (161mm~230mm)", the interface displays "This range is suitable for long airbag watch straps". Of course, in other embodiments, the electronic device 100 can also automatically measure the user's wrist to obtain the user's wrist circumference data. Alternatively, the wrist circumference data can also be input during the process of recognizing the watch strap 20.

[0159] S320: Obtain the magnetic poles of the watch strap 20.

[0160] Specifically, such as Figure 5 and Figure 23 The electronic device 100 includes a table body 10 ( Figure 1The watch strap 20 has an airbag 50 on its inner side. In this embodiment, the watch strap 20 has three types: a short airbag strap, a long airbag strap, and a regular strap. Both the short airbag strap and the long airbag strap have airbags, while the regular strap does not. The short airbag strap has a first airbag, the long airbag strap has a second airbag, and the first and second airbags have different lengths. The regular strap includes a cover plate. The short airbag strap is the first strap, and the long airbag strap and the regular strap are the second straps.

[0161] When measuring blood pressure, users with different wrist circumferences can choose watch straps 20 with different airbag lengths as needed. This ensures that the airbags in watch strap 20 can fully cover the radial and ulnar arteries while also preventing the watch strap from becoming excessively long, thus guaranteeing a good user experience. When not measuring blood pressure, users can choose a regular watch strap for improved wearing comfort.

[0162] The watch body 10 is equipped with a Hall sensor 16, and the air bladder 50 or cover plate of the watch strap 20 is equipped with a magnet. The first and second watch straps have different ways of setting the magnets in their air bladders or covers. When the watch strap 20 is the first watch strap, it is mounted on the watch body 10, and the first magnetic pole of the first magnet is positioned opposite the Hall sensor 16 on the watch body 10. When the watch strap 20 is the second watch strap, it is mounted on the watch body 10, and the second magnetic pole of the second magnet is positioned opposite the Hall sensor 16 on the watch body 10. The first and second magnetic poles are different. Specifically, the first magnetic pole is the S pole, and the second magnetic pole is the N pole. Since the Hall sensor 16 can detect changes in the magnetic field, and the magnetic poles of different watch straps 20 are different, the watch body 10 can identify whether the watch strap 20 is the first or second watch strap by recognizing the magnetic poles.

[0163] Before acquiring the magnetic poles of the watchband 20, the process also includes receiving a watchband 20 identification command. It is understood that when the processor 13 detects certain user actions, the processor 13 can send a watchband 20 identification command to the Hall sensor 16. For example, when the processor 13 detects that the user has completed entering wrist circumference data and clicked "Next," it sends the watchband 20 identification command to the Hall sensor 16. Or, when the processor 13 detects that the user turns on the electronic device 100 for the first time. Or, when the processor 13 detects that the user opens the blood pressure measurement function page of the electronic device 100, it sends the watchband 20 identification command to the Hall sensor 16. Or, when the processor 13 detects that the user installs the watchband 20 onto the watch body 10, it sends the watchband 20 identification command to the Hall sensor 16.

[0164] like Figure 26 and Figure 27After receiving the identification command from the watch strap 20, the Hall sensor 16 can send a confirmation message to the user interface indicating whether to perform a test. The user interface displays "To ensure normal pressure application, the watch strap installation needs to be checked before measurement. Start testing?" The user clicks "√" to confirm the test and "×" to cancel. When the user clicks "√", the user interface displays "Testing in progress".

[0165] During the testing process, electronic device 100 first checks whether the user is wearing electronic device 100. If the user is not wearing electronic device 100, ... Figure 28 The user interface displays the message "Please wear electronic device for measurement" and an icon prompting the user to wear electronic device 100. If the user is wearing electronic device 100, the magnetic poles of the watch strap 20 are detected. Specifically, the processor 13 sends a watch strap 20 identification command to the Hall sensor 16. After receiving the watch strap 20 identification command, the Hall sensor 16 detects the magnetic poles of the watch strap 20 to obtain the magnetic poles of the watch strap 20.

[0166] S330: Confirm that the watch strap 20 is the first watch strap or the second watch strap based on the magnetic poles of the watch strap 20.

[0167] Specifically, such as Figure 23 If the Hall sensor detects the magnetic field of the first magnetic pole, then the strap 20 is the first strap, that is, the strap 20 is the short airbag strap; if the Hall sensor detects the magnetic field of the second magnetic pole, then the strap 20 is the second strap. The first strap is suitable for users with smaller wrist circumferences to measure blood pressure. For example, the first strap can be used for users with wrist circumferences in the range of 130mm to 160mm (inclusive).

[0168] Of course, if the magnetic poles of the watch strap 20 are non-magnetic, then the airbag or cover is not installed on the watch body 10, or the airbag or cover is detached from the watch body 10.

[0169] S340: If the watch strap 20 is the second watch strap, then inflate the watch strap 20 and obtain the slope of the pressure curve of the watch strap 20.

[0170] Specifically, such as Figure 23If the watch strap 20 is the second watch strap, it indicates that the second watch strap is either a long airbag strap or a regular watch strap. It is understood that the air pump 141 inside the watch body 10 can inflate the second watch strap. Since the long airbag strap has an airbag, while the regular watch strap does not, the pressure sensor 142 detects different pressure changes when the long airbag strap and the regular watch strap are inflated. Because the regular watch strap does not have an airbag and cannot store gas, the pressure curve slope of the regular watch strap will rise rapidly at a fixed slope in a short period of time. Since the long airbag strap has an airbag, the pressure curve slope of the long airbag strap will rise slowly at a fixed slope over a period of time. The different pressure curve slopes of the long airbag strap and the regular watch strap in the inflated state are the test data. The test data of the second watch strap is compared with predetermined data (the pressure curve slopes of the long airbag strap and the regular watch strap).

[0171] If the pressure curve slope of the second strap matches that of the long airbag strap, then the test data is the first data, and the second strap is the long airbag strap. The second strap is suitable for users with larger wrist circumferences, for example, users with wrist circumferences ranging from 161mm to 230mm (inclusive). If the pressure curve slope of the second strap matches that of the regular strap, then the test data is the second data, and the second strap is the regular strap. The regular strap is suitable for users to wear when not measuring blood pressure, improving user comfort.

[0172] Of course, in other embodiments, while the Hall sensor 16 identifies the magnetic poles of the watch strap 20, the air pump 141 inside the watch body 10 can inflate the watch strap 20. That is, steps S330 and S340 can be performed simultaneously to quickly confirm whether the watch strap 20 is a normal watch strap. Thus, the processor 13 can quickly determine the type of watch strap 20 based on the combined results of the Hall sensor 16 and the magnetic poles working together and the inflation method of the watch strap 20.

[0173] Alternatively, when the processor 13 identifies that the user's wrist circumference data corresponds to a long airbag watch strap, the controller can control the Hall sensor 16 to identify the magnetic poles of the watch strap 20 and the air pump 141 inside the watch body 10 to inflate the watch strap 20 to identify the watch strap 20. It can be understood that steps S330 and S340 are performed simultaneously to confirm whether the watch strap 20 is a normal watch strap in a short time. Thus, the processor 13 can quickly determine the type of watch strap 20 in a short time based on the combined results of the Hall sensor 16 and the magnetic poles working together and the way the watch strap 20 is inflated.

[0174] S350: Compares the type of watch strap 20 with the user's wrist circumference data and sends the comparison result to the user interface.

[0175] Specifically, such as Figure 23 When step S340 determines that the watch strap 20 is a regular watch strap, such as Figure 29 The system detects that the airbag-equipped watch strap 20 is not installed. A user interface recommending the watch strap 20 appears, displaying the message: "Based on your wrist circumference, we recommend a short airbag watch strap (or a long airbag watch strap). Please install the watch strap according to the diagram before measuring." The interface also shows a diagram illustrating the installation of the watch strap 20.

[0176] When steps S330 and S340 determine that the watch strap 20 is a long airbag watch strap, the long airbag watch strap is compared with the wrist circumference data to determine whether the watch strap 20 corresponding to the wrist circumference data is indeed a long airbag watch strap. For example... Figure 30 If the wrist circumference data corresponds to a long airbag watch band (band 20), the user interface will display "Based on your wrist circumference, a long airbag watch band is recommended. We have detected that you have installed the appropriate watch band; you can begin measuring your blood pressure." To measure blood pressure, click "Next." Figure 31 If the watch band 20 corresponding to the wrist circumference data is not a long airbag watch band, the user interface will display "Based on your wrist circumference, a short airbag watch band is recommended. The currently installed watch band does not match the recommended watch band. Please check your wrist circumference settings or change the watch band and measure again." Users can click "Previous" or "OK" as needed.

[0177] When steps S330 and S340 determine that the watch strap 20 is a short airbag strap, the short airbag strap is compared with the wrist circumference data to determine whether the watch strap 20 corresponding to the wrist circumference data is indeed a short airbag strap. If the watch strap 20 corresponding to the wrist circumference data is a short airbag strap, the user interface displays "Based on your wrist circumference, a short airbag strap is recommended. The system has detected that you have installed the corresponding strap; you can begin measuring blood pressure." To measure blood pressure, the user can click "Next." If the watch strap 20 corresponding to the wrist circumference data is not a short airbag strap, the user interface displays "Based on your wrist circumference, a long airbag strap is recommended. The system has detected that the currently installed strap does not match the recommended strap. Please check your wrist circumference settings or change the strap before measuring." The user can click "Previous" or "OK" as needed.

[0178] This embodiment identifies the type of watch strap 20 installed on the watch body 10, compares the identification structure with the user's wrist circumference, and sends the comparison result to the user interface. The user can then determine whether they are wearing the wrong watch strap based on the identification result and, upon prompting, replace the watch strap 20 or perform subsequent operations, avoiding the problem of decreased blood pressure accuracy caused by using the wrong watch strap. Furthermore, if the user receives a message from the electronic device 100 indicating that the watch body 10 is not equipped with the watch strap 20, they can install the watch strap 20 on the watch body 10 or check if the watch strap 20 is loose, preventing water damage to the device caused by washing hands or showering when the watch strap 20 is loose.

[0179] Understandably, the electronic device 100 can support storing wrist circumference data from multiple users. When the electronic device 100 has stored wrist circumference data from only one user, that user's wrist circumference data is directly retrieved for comparison in step 350. When the electronic device 100 has stored wrist circumference data from multiple users, during the recognition process of the watch strap 20, the user can select their own wrist circumference data for comparison.

[0180] Of course, in other embodiments, the electronic device 100 can also identify the type of watch strap 20 without using the Hall sensor 16 and magnet 54. For example, the type of watch strap 20 can be identified by inflating it. Specifically, after receiving the watch strap 20 identification command, the processor 13 controls the air pump 141 to inflate the watch strap 20, and the pressure sensor 142 acquires the air pressure change value to obtain the slope of the pressure curve of the watch strap 20 in the inflated state. It is understood that the airbag lengths of long airbag watch straps and short airbag watch straps are different, and ordinary watch straps have no airbags. Therefore, the slopes of the pressure curves of the three are different. The slopes of the pressure curves of the three can be stored in the processor 13 in advance. By comparing the obtained pressure curve slope with the pre-stored pressure curve slope, it can be determined whether the watch strap 20 is a long airbag watch strap, a short airbag watch strap, or an ordinary watch strap.

[0181] The above are merely some embodiments and implementation methods of this application. The scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
