[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] Some wearable devices on the market currently measure the user's blood pressure by setting up an airbag. Such wearable devices usually require one airbag. When working, the airbag is inflated to compress the skin, and the pressure sensor is used to detect the pressure change in the airbag, thereby realizing the measurement of physiological parameters such as blood pressure and pulse. In order to inflate the airbag, an air pump and an air guide structure need to be set in the wearable device. The airflow generated by the air pump is guided into the airbag through the air guide structure. The current air guide structure is mostly equipped with multiple pipes, such as silicone pipes. Due to the small size of the wearable device and the presence of various other components in the internal space, it is easy to interfere with the air guide structure, which results in the need for an avoidance design of the air guide structure, resulting in a large number of parts for the air guide structure and difficulty in assembly.

[0032] Based on this, the inventor of the present application proposes a wearable device according to each embodiment of the present application, in order to improve the above-mentioned defects. The embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0033] Example

[0034] like Figure 1 As shown, this embodiment provides a wearable device 10, which is suitable for being worn on a user's wrist. The wearable device 10 may be, but is not limited to, a wristband, a smart watch, etc. The wearable device 10 of this embodiment is described by taking a smart watch as an example.

[0035] Please also read Figure 1 and Figure 2 The wearable device 10 includes a main body 30, a belt 20, an inflatable component 70 and a pressure sensor 60. The main body 30 can be used to set a human-machine interaction device such as a display screen 40. The belt 20 is connected to the main body 30 and is mainly used for being worn by the user. In this embodiment, the main body 30 is a dial, and the belt 20 is a strap. In some embodiments of the present application, a header mechanism is also provided, which is configured to be connected to a strap mechanism. It can be understood that the header mechanism can be a part of the above-mentioned wearable device 10. For example, the header mechanism can include the main body 30, and the strap mechanism can include the belt 20. The relevant features of the header mechanism and the strap mechanism can refer to the relevant features of the wearable device 10.

[0036] See also Figure 3 The main body 30 includes a middle frame 32 and a bottom shell 31. The bottom shell 31 is assembled on the middle frame 32 and forms a receiving space 38 between the bottom shell 31 and the middle frame 32. The receiving space 38 can be used to receive part of the inflatable component 70 and the pressure sensor 60. Specifically, Figure 4As shown, the middle frame 32 includes a main body 321 and two connecting parts 322. The main body 321 is configured as a roughly rectangular frame structure. The bottom shell 31 is assembled on the main body 321. A mounting groove 323 is formed on the side of the main body 321 away from the bottom shell 31.

The display screen 40 can be used to display various information of the wearable device 10, such as time, weather, and other human-computer interactions. In this embodiment, the display screen 40 can also be used to display measured physiological parameters. It can be understood that the physiological parameters include but are not limited to blood pressure, pulse, blood sugar, etc.

[0037] In some other embodiments, the mounting slot 323 may not be provided with the display screen 40. For example, the mounting slot 323 may be provided with a mechanical dial. The two connecting portions 322 are connected to opposite ends of the main body 321. Specifically, the two connecting portions 322 are connected to the two ends of the length direction of the main body 321. The belt body 20 is connected to the two connecting portions 322.

[0038] In some embodiments, the connection portion 322 may also be provided with an installation opening toward the bottom, so that the belt body 20 can be connected to the main body 30 from the bottom surface of the main body 30 (the side where the bottom shell 31 is located). In this embodiment, the connection portion 322 is provided toward the bottom so that the upper shell can reserve more space for setting the display screen, for example, the display screen is provided on the entire upper shell. It can be understood that when the installation opening of the connection portion 322 is provided on the lower side of the main body 30, the relevant structure can refer to the relevant embodiment provided on the upper side in this application (as shown in the relevant drawings), and the relevant structure can be adaptively adjusted in the direction.

[0039] In some embodiments, the connecting portion 322 may also be provided with a connecting piece for connecting the belt body 20, such as a hinge shaft 326. The belt body 20 may be an integral structure and connected to the hinge shafts 326 of the two connecting portions 322 of the main body 30. For example, the belt body 20 may be made of an elastic material and may be elastically retractable during wearing. In some embodiments, the belt body 20 may include a first belt body and a second belt body. The first belt body and the second belt body may be respectively connected to the hinge shafts 326 of the two connecting portions 322 of the main body 30, and the end of the first belt body away from the main body 30 and the end of the second belt body away from the main body 30 may be detachably connected, for example, by being fixed by a buckle. The belt body 20 may be made of metal, leather, fabric, plastic, silicone, and other materials, which are not limited in this embodiment.

[0040] The connecting portion 322 is provided with an air nozzle 327 , which extends into the receiving space 38 . The air nozzle 327 can be used to communicate with the air path in the receiving space 38 , thereby inflating the airbag 75 .

[0041] In some embodiments, when the belt body 20 is connected to the main body 30 , the airbag 75 is synchronously connected to the air path, thereby achieving synchronous connection, thereby improving assembly efficiency and facilitating user use.

[0042] In some embodiments, the inflatable component 70 includes an air pump component 71, an air bag 75, and an air circuit 35. The air pump component 71 is disposed on the main body 30, the air pump component 71 is connected to the air circuit 35, the air bag 75 is disposed on the belt body 20 and is connected to the air circuit 35, and the air pump component 71 is used to inflate the air bag 75. The air bag 75 is disposed on the belt body 20 and can be disposed on the surface of the belt body 20 facing the user's skin.

[0043] Figure 5 The disassembled structure of the inflatable component 70 at a first viewing angle is shown. Figure 6 The disassembled structure of the inflatable component 70 at the second viewing angle is shown. The first viewing angle and the second viewing angle are opposite to each other. Figure 5 and Figure 6 The inflation component may further include a valve 72 , the valve 72 includes an air inlet 721 and a first air outlet 722 , wherein the air inlet 721 may be connected to the air pump component 71 for air intake, and the first air outlet 722 may be connected to the airbag 75 .

[0044] The air pump assembly 71 is disposed in the main body 30. For example, the air pump assembly 71 is disposed in the receiving space 38 formed in the main body 30. The air pump assembly 71 is used to inflate the airbag 75. In this embodiment, a main board can be disposed in the receiving space 38 of the main body 30. The air pump assembly 71 includes an air pump 711 and an air guide 712. The air guide 712 is connected to the air inlet 721 and the air pump 711. The air pump 711 can be connected to the main board through a flexible circuit board to realize the control of the air pump 711.

[0045] The air guide 712 is connected to the air inlet 721 and the air outlet 7111 of the air pump 711, and then guides the air flow pumped out by the air pump 711 into the air inlet 721. In some embodiments, the air guide 712 can be, for example, an air pipe or other structure. Figure 5 and Figure 6The air guide member 712 includes a first cover plate 713 and a second cover plate 714. The first cover plate 713 is attached to the second cover plate 714. The surface of the first cover plate 713 facing the second cover plate 714 forms an air guide groove 717. The first cover plate 713 is provided with a first through hole 715 connected to the air guide groove 717. The first through hole 715 is connected to the air outlet 7111 of the air pump 711. The second cover plate 714 is provided with a second through hole 716 connected to the air guide groove 717. The air inlet 721 is connected to the second through hole 716. When the air pump 711 is working, air flow is pumped out from the air outlet 7111. The air flow enters the air guide groove 717 through the first through hole 715 and then enters the air inlet 721 through the second through hole 716. The sizes of the first cover plate 713 and the second cover plate 714 can be roughly set to be equivalent to the air pump 711. The position of the first through hole 715 corresponds to the air outlet 7111 of the air pump 711. During assembly, the surface of the first cover plate 713 away from the second cover plate 714 can be attached to the air pump 711, making the entire assembly structure more compact and easier to assemble. It is understandable that in order to improve the sealing of the connection between the air guide 712 and the air pump 711 and the valve 72, a sealing ring can also be set at the connection between the first through hole 715 and the air outlet 7111 of the air pump 711 and the connection between the second through hole 716 and the air inlet 721. The sealing ring can be made of plastic, silicone or other materials.

[0046] Please also read Figure 7 and Figure 8 The main body 30 is also provided with an air circuit 35, and the first air outlet 722 is connected to the air circuit 35. The air circuit 35 is used to supply air to the airbag 75 when the inflatable component is working. The pressure sensor 60 is provided in the air circuit 35. The pressure sensor 60 is used to detect the pressure of the airbag 75, and then the wearable device 10 can obtain the pressure value of the airbag 75, and then obtain the physiological parameters of the user according to the pressure value.

[0047] In some embodiments, see Figure 3 The main body 30 further includes an air guide cover 365, which is disposed on the bottom shell 31 and forms a closed air guide channel 338 ( Fig.11 ), that is, the air guide channel 338 is formed between the air guide cover plate 365 and the bottom shell 31, and the air guide channel 338 is formed by the bottom shell 31. The air guide channel 338 is at least a part of the air circuit 35, and no additional components such as the air pipe 354 are required, thereby reducing the number of components of the air circuit 35 and facilitating assembly. In this embodiment, the air circuit 35 also includes an air chamber 350, which is connected to the first air outlet 722 and the air guide channel 338.

[0048] It can be understood that in some embodiments, the aforementioned watch head mechanism may include: a main body 30, an air pump assembly 71 and a pressure sensor 60. The main body 30 may include a shell, a middle frame 32 and an air guide cover 365. In some embodiments, the shell may only include a bottom shell 31. In some embodiments, the shell may also include an upper shell (not shown), which may be assembled with the bottom shell 31, and the upper shell may be used to install a display screen. The middle frame 32 is assembled to the shell and forms a receiving space 38. The receiving space 38 is provided with an air path 35. The air guide cover 365 is arranged in the receiving space 38 and forms an air guide channel 338 with the shell. The air guide channel 338 may serve as at least a part of the air path 35. The air pump assembly 71 is arranged in the receiving space 38. The air pump assembly 71 is connected to the air path 35. The air path 35 is configured to be connected to the air bag 75 of the strap mechanism for inflating the air bag 75. The pressure sensor 60 is arranged in the air path 35. Specifically, the structures of the main body 30 , the air pump assembly 71 and the pressure sensor 60 can refer to the above or below contents, which will not be repeated here.

[0049] The air guide cover plate 365 may form an air guide channel 338 with the bottom shell 31. In another embodiment, when the housing further includes an upper shell, the air guide cover plate 365 may also form an air guide channel 338 with the upper shell, which is not limited in this embodiment. For example, the air guide cover plate 365 may also be disposed on the side close to the display screen, and may form a closed air guide channel with the upper shell.

[0050] It can be understood that in this embodiment, please refer to Figure 7 and Figure 8 The air circuit 35 includes a shell 351, a cover 352 and a bottom plate 333. The shell 351 is mounted on the bottom plate 333, and the cover 352 is mounted on the end of the shell 351 away from the bottom plate 333. The shell 351, the cover 352 and the bottom plate 333 enclose a closed air chamber 350. The bottom plate 333 is a roughly flat plate structure, and the shell 351 is a roughly hollow columnar structure. The cover 352 is provided with an air inlet 3522 and an air outlet 3521. The air inlet 3522 and the air outlet 3521 are both connected to the accommodating cavity in the air chamber 350. The air inlet 3522 and the air outlet 3521 can be configured as a roughly columnar structure and protrude from the surface of the cover 352. During assembly, the pressure sensor 60 is pre-installed in a predetermined position of the bottom plate 333 and fixed to the bottom plate 333, and then the housing 351 and the cover 352 are assembled by bonding or the like to form a closed air chamber 350. The air inlet 3522 is connected to the first air outlet 722 through the air pipe 354, so that the first air outlet 722 is connected to the air chamber 350. The air pipe 354 can be configured into any shape according to the space between the air chamber 350 and the first air outlet 722, and this embodiment does not limit this.

[0051] In this embodiment, please refer to Fig. 9 , Fig.10 as well as Fig.11 The guide groove 3651 is provided on one side of the air guide cover plate 365 facing the bottom shell 31. The guide groove 3651 constitutes at least a part of the air guide channel 338. It can be understood that the other space between the air guide cover plate 365 and the bottom shell 31 can also be used as a part of the air guide channel 338. The guide groove 3651 is connected to the air outlet 3521 of the air chamber 350, and then guides the airflow filled from the first air outlet 722 into the air guide channel 338. By providing the guide groove 3651, it is easy to communicate with the air outlet 3521 on the cover 352, and form a better sealing effect; at the same time, it can also increase the volume in the air guide channel 338. When the airflow enters the air guide channel 338, the flow rate will not change due to the change in cross-sectional area, causing noise.

[0052] The guide groove 3651 can be a strip groove, a rectangular groove, etc., which is not limited here. In this embodiment, the guide groove 3651 is a runway-shaped structure. This arrangement can be well matched with the air outlet 3521 on the cover 352. When the air outlet 3521 is embedded in the guide groove 3651, it can better fit with the groove wall of the guide groove 3651, and the sealing performance is better.

[0053] The air guide cover plate 365 is further provided with a first communication hole 3652 and a second communication hole 3653. The first communication hole 3652 and the second communication hole 3653 are both connected to the guide groove 3651. The first communication hole 3652 is used to communicate with the air pump assembly. In this embodiment, the first communication hole 3652 is connected to the air outlet 3521 of the air chamber 350 and then communicates with the air pump assembly. The second communication hole 3653 is used to communicate with the airbag 75. In this embodiment, the second communication hole 3653 is connected to the air nozzle 327 and then communicates with the airbag 75. During assembly, the air outlet 3521 is embedded in the first communication hole 3652, the air nozzle 327 is embedded in the second communication hole 3653, the guide groove 3651 is set toward the bottom shell 31, and the bottom shell 31 covers the guide groove 3651, thereby closing the guide groove 3651. At this time, the space between the air guide cover plate 365 and the bottom shell 31 forms an air guide channel 338. This arrangement can fully utilize the space between the air guide cover plate 365 and the bottom shell 31 for air guide, which not only reasonably utilizes the space but also reduces the number of parts. In addition, during the assembly process, only the air guide cover plate 365 needs to be assembled, which increases the assembly efficiency.

[0054] Furthermore, the first connecting hole 3652 and the second connecting hole 3653 penetrate the surface of the air guide cover plate 365 away from the bottom shell 31. During assembly, the air outlet 3521 and the air nozzle 327 are both installed from the surface of the air guide cover plate 365 on the principle bottom shell 31 and communicate with the guide groove 3651, which is convenient for overall assembly. It can be understood that the first connecting hole 3652 and the second connecting hole 3653 can also penetrate other surfaces of the air guide cover plate 365, and it is only necessary to ensure that the air outlet 3521 and the air nozzle 327 can be more conveniently installed in the first connecting hole 3652 and the second connecting hole 3653.

[0055] In some embodiments, for the header mechanism, the air guide cover 365 may be provided with a guide groove 3651 on the surface facing the bottom shell 31, and the air guide cover 365 is provided with a first connecting hole 3652 and a second connecting hole 3653. The first connecting hole 3652 and the second connecting hole 3653 are both connected to the guide groove 3651, the first connecting hole 3652 is used to connect with the air pump assembly 71, and the second connecting hole 3653 is used to connect with the airbag 75; the bottom shell 31 and the guide groove 3651 constitute a part of the air path 35.

[0056] In other embodiments, for the header mechanism, the air guide cover 365 can be provided with a guide groove 3651 on the surface facing the upper shell, and the air guide cover 365 is provided with a first connecting hole 3652 and a second connecting hole 3653. The first connecting hole 3652 and the second connecting hole 3653 are both connected to the guide groove 3651, the first connecting hole 3652 is used to connect with the air pump assembly 71, and the second connecting hole 3653 is used to connect with the airbag 75; the upper shell and the guide groove 3651 constitute a part of the air path 35.

[0057] In this embodiment, the air nozzle 327 also has a step surface 328, which is inclined relative to the axial direction of the air nozzle 327. The axial direction of the air nozzle 327 is substantially parallel to the axial direction of the air outlet 3521, which is conducive to the air guiding channel 338 to guide air. In order to better cooperate with the air nozzle 327, the air guiding cover plate 365 is provided with an inclined surface 3654, wherein the second connecting hole 3653 is opened on the inclined surface 3654, the inclined surface 3654 cooperates with the step surface 328, and the inclined surface 3654 can overlap the step surface 328, so that the connection between the air guiding cover plate 365 and the air nozzle 327 is more stable.

[0058] Please refer again Figure 2The wearable device 10 may further include a control unit 50, which may be disposed in the main body 30 and used to control other electronic components, such as controlling the opening or closing of the air pump 711 and the opening or closing of the valve 72, and the connection or disconnection of the first air outlet 722 of the air pump 711. At the same time, the control unit 50 may also be electrically connected to the pressure sensor 60 and obtain the pressure information of the airbag 75 collected by the pressure sensor 60. In this embodiment, the control unit 50 is also used to calculate the blood pressure value of the user according to the pressure information of the airbag 75 collected by the pressure sensor 60.

[0059] The control unit 50 may include a processor and a memory, wherein the processor may include one or more processing cores. The processor uses various interfaces and lines to connect the various parts of the entire wearable device 10, and executes various functions of the electronic device and processes data by running or executing instructions, programs, code sets or instruction sets stored in the memory, and calling data stored in the memory. Optionally, the processor can be implemented in at least one hardware form of digital signal processing (DSP), field-programmable gate array (FPGA), and programmable logic array (PLA). The processor can integrate one or a combination of a central processing unit (CPU), a graphics processing unit (GPU), and a modem. Among them, the CPU mainly processes the operating system, user interface, and application programs; the GPU is responsible for rendering and drawing display content; and the modem is used to process wireless communications.

In particular, the axial direction of the first air outlet 722 and the axial direction of the second air outlet 723 can also be coaxially arranged. The air inlet 721 is located between the first air outlet 722 and the second air outlet 723, and the axial direction of the air inlet 721 can be perpendicular to the axial direction of the first air outlet 722 and the axial direction of the second air outlet 723.

The second air pipe 344 can be configured into any shape according to the space between the second air chamber 340 and the second air outlet 723, and this embodiment does not limit this.

[0074] Please refer again Fig.19 The first connecting hole 3652 of the second air guide cover plate 345 is connected to the air outlet 3421 of the second air chamber 340, so that the second air guide channel 337 can be used to connect to the air outlet of the second air chamber 340, and the second air guide channel 337 can also be routed in the form of an air pipe.

[0075] In this embodiment, please continue to refer to Fig.19 The second air guide cover plate 345 is arranged on the bottom shell 31, and forms a closed second air guide channel 337 between the second air guide cover plate 345 and the bottom shell 31, that is, the second air guide channel 337 is formed between the second air guide cover plate 345 and the bottom shell 31, and the second air guide channel 337 is formed by using the bottom shell 31, and there is no need to add other additional components such as air pipes.

[0076] In this embodiment, the valve 72 is fixed to the bottom plate 333 and / or on the bottom plate 333 , and the air inlet 721 passes through the bottom plate 333 and communicates with the exhaust port of the air pump 711 .

[0077] The first air guide channel 336 is connected to the first airbag 73 to guide the airflow into the first airbag 73. Similarly, the second air guide channel 337 is connected to the second airbag 74 to guide the airflow into the second airbag 74. In this embodiment, the connecting portion 322 is provided with an air nozzle 327. The air nozzle 327 includes a first air nozzle 324 for connecting to the first airbag 73 and a second air nozzle 325 for connecting to the second airbag 74. One end of the first air nozzle 324 extends into the receiving space 38 and is connected to the first air path 33. One end of the second air nozzle 325 extends into the receiving space 38 and is connected to the second air path 34. Specifically, one end of the first air nozzle 324 extending into the receiving space 38 is configured as a substantially hollow columnar structure, and one end of the second air nozzle 325 extending into the receiving space 38 is configured as a substantially hollow columnar structure. One end of the first air nozzle 324 extending into the receiving space 38 is embedded in the second communication hole 3653 of the first air guide cover plate 335, so that the first air nozzle 324 is connected to the guide groove 3651 of the first air guide cover plate 335 to form a closed structure. One end of the second air nozzle 325 extending into the receiving space 38 is embedded in the second communication hole 3653 of the second air guide cover plate 345, so that the second air nozzle 325 is connected to the guide groove 3651 of the second air guide cover plate 345 to form a closed structure.

[0078] The first air nozzle 324 and the second air nozzle 325 can be integrally prepared with the connecting portion 322, so that the first air nozzle 324 and the second air nozzle 325 are formed together in the process of forming the main body 30. It is understandable that in some other embodiments, the first air nozzle 324 and the second air nozzle 325 may not be provided, and other methods are used to achieve the communication between the first airbag 73 and the first air guide channel 336, and the communication between the second airbag 74 and the second air guide channel 337. For example, a through hole is provided in the connecting portion 322, and part of the airbag is extended into the receiving space 38 to communicate with the first air guide channel 336 or the second air guide channel 337.

[0079] The first airbag 73 is connected to the first air nozzle 324 located at the connecting portion 322, and the second airbag 74 is connected to the second air nozzle 325 located at the connecting portion 322. In this arrangement, since the first air nozzle 324 and the second air nozzle 325 can be integrally formed with the connecting portion 322, during assembly, the first airbag 73 and the second airbag 74 can be easily connected, assembled and sealed with the first air nozzle 324 and the second air nozzle 325, thereby improving the assembly efficiency of the wearable device 10. At the same time, since the first airbag 73 and the second airbag 74 are both located outside the main body 30, during the inflation process, the first airbag 73 and the second airbag 74 will not be interfered by the main body 30, thereby improving the safety of the inflation process and the measurement accuracy.

[0080] The wearable device 10 provided in the above embodiment can be used to measure the blood pressure of the user. As an example, the measurement method can be performed in the following manner:

[0081] When the user wears the wearable device 10 on the wrist, in response to the user's measurement instruction, the air pump 711 is controlled to turn on, the first air outlet 722 is opened, the second air outlet 723 is closed, and air is inflated into the first airbag 73. The air pressure value in the first airbag 73 is detected in real time through the first pressure sensor 61.

[0082] Among them, the measurement instruction refers to an instruction issued by the user to perform a blood pressure test, which is used to instruct the wearable device 10 to perform blood pressure measurement. The measurement instruction can be issued by operating the wearable device 10, for example, a physical button or a virtual button is set on the main body 30 of the wearable device 10, and the user issues the measurement instruction by operating the physical button or the virtual button. In another embodiment, the wearable device 10 can also be connected to the user's mobile phone, tablet computer and other devices wirelessly or wiredly, and the user can send a measurement instruction to the wearable device 10 through a mobile phone, tablet computer and other devices. When the first airbag 73 is inflated, the first airbag 73 expands and presses the user's wrist skin. The air pressure value in the first airbag 73 is collected in real time through the first pressure sensor 61, and the external pressure value of the current user's skin can be determined. The external pressure value is equal to the pressure value of the first airbag 73.

[0083] During the inflation process, the air pressure in the first airbag 73 gradually increases, and the pressure on the user's skin becomes stronger. At this time, the user's radial artery is compressed, and the pulse wave changes. When the air pressure in the first airbag 73 reaches a certain threshold, the pulse wave disappears to 0. When the air pressure in the first airbag 73 increases to the point where the pulse wave disappears, the current air pressure in the first airbag 73 is recorded as the systolic pressure value. The pulse wave can be measured by a pulse wave sensor disposed in the main body 30, which is not described in detail in this embodiment.

[0084] After obtaining the user's systolic pressure through the first airbag 73, turn off the air pump 711 and deflate the first airbag 73. When the air pressure value is reduced to the maximum of the pulse wave, the current external pressure value is recorded as the diastolic pressure value, and the pressure measurement is completed. It should be noted that systolic pressure is also called "high pressure", which represents the highest pressure of blood pressure, and diastolic pressure is also called "low pressure", which represents the lowest pressure of blood pressure.

[0085] After the first airbag 73 is deflated, the air pump 711 is controlled to start, the second air outlet 723 is opened, the first air outlet 722 is closed, and air is inflated into the second airbag 74. The air pressure value in the second airbag 74 is detected by the second pressure sensor 62. During the inflation process, the air pressure value in the second airbag 74 gradually increases, and the pressure on the user's skin becomes stronger. At this time, the user's radial artery is compressed, and the pulse wave changes. When the air pressure value in the second airbag 74 reaches a certain threshold, the pulse wave disappears and becomes 0. When the air pressure value in the second airbag 74 increases to the point where the pulse wave disappears, the current air pressure value in the second airbag 74 is recorded as the systolic pressure value.

[0086] After obtaining the user's systolic pressure through the second airbag 74, the air pump 711 is turned off to deflate the second airbag 74. When the air pressure value is reduced to the maximum of the pulse wave, the current external pressure value is recorded as the diastolic pressure value, and the pressure measurement is completed.

[0087] The user's blood pressure parameter may be obtained by processing the systolic pressure and diastolic pressure obtained by the first airbag 73 and the systolic pressure and diastolic pressure obtained by the second airbag 74 .

[0088] The wearable device 10 provided in this embodiment forms a first air guide channel 336 between the first air guide cover plate 335 and the bottom shell 31 as at least a part of the first air path 33, and forms a second air guide channel 337 between the second air guide cover plate 345 and the bottom shell 31 as at least a part of the second air path 34. The air path 35 is formed by using the bottom shell 31 of the main body 30, which can reduce the components of the air guide structure and the installation space for installing the air guide structure, making assembly easier and making the wearable device 10 thinner and lighter.

[0089] At the same time, the wearable device 10 provided in this embodiment is provided with a first airbag 73 and a second airbag 74, and the measurement of the physiological parameters of the user is achieved by inflation and deflation of the first airbag 73 and the second airbag 74, which can significantly improve the measurement accuracy of the physiological parameters. At the same time, since the inflation component 70 only uses one air pump component 71, the inflation of the first airbag 73 and the second airbag 74 is controlled by the valve 72, and there is no need to add an additional air pump 711, which reduces the space occupied by the main body 30 and avoids increasing the volume of the main body 30.

[0090] The "wearable device 10" used in the embodiments of the present application includes, but is not limited to, a device configured to receive / send communication signals via a wired line connection (such as via a public switched telephone network (PSTN), a digital subscriber line (DSL), a digital cable, a direct cable connection, and / or another data connection / network) and / or via a wireless interface (for example, for a cellular network, a wireless local area network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and / or another communication terminal).
