Description

Technical Field

[0001] This application relates to the field of electronic products, specifically to a wearable device and a watch head mechanism. Background Technology

[0002] With the continuous development of society, work pressure in all walks of life is gradually increasing. Sudden death cases occur frequently, and most cardiac arrests are not detected in time, directly leading to sudden death. In recent years, the trend of sudden death has become more pronounced among younger people, due to factors such as continuous late nights, high-intensity work, and mental stress. Existing health checkup equipment is often concentrated in hospitals and medical centers, requiring advance appointments, meaning people can only have occasional checkups, such as once a year, which is a very low frequency of health monitoring. While routine indicators such as blood pressure, heart rate, and body temperature can be monitored at home with devices like blood pressure monitors and thermometers, allowing for daily monitoring, these instruments are inconvenient to carry, preventing real-time monitoring and alerts for health status.

[0003] Among related technologies, some wearable devices such as monitoring bracelets and watches have emerged to monitor users' body data. Some of these wearable devices can be used to measure users' blood pressure values, but these wearable devices require a lot of tubing for air delivery, resulting in numerous parts and complex assembly. Summary of the Invention

[0004] The purpose of this application is to provide a wearable device and a watch head mechanism to improve the above-mentioned technical problems.

[0005] In a first aspect, embodiments of this application provide a wearable device, including a main body, a strap, an inflation assembly, and a pressure sensor. The main body includes a bottom shell, a middle frame, and an air guide cover. The middle frame is assembled to the bottom shell and forms a receiving space.

The air pump assembly is disposed in the main body and is connected to the air passage. The airbag is disposed in the strap and is connected to the air passage. The pressure sensor is disposed in the air passage.

[0006] The wearable device provided in this application embodiment forms an air passage between the air guide cover and the bottom shell as at least part of the air path. By using the bottom shell of the main body to form the air path, the number of parts of the air guide structure can be reduced, the installation space for installing the air guide structure can be reduced, the assembly can be made simpler, and the wearable device can be made thinner and lighter.

[0007] Secondly, embodiments of this application also provide a watch head mechanism for connection to a watch strap mechanism. The watch head mechanism includes a main body, an air pump assembly, and a pressure sensor. The main body includes a housing, a middle frame, and an air guide cover. The middle frame is assembled into the housing and forms a receiving space. An air passage is provided within the receiving space. The air guide cover is disposed within the receiving space and forms an air guide channel with the housing. The air guide channel is at least a part of the air passage. The air pump assembly is disposed within the receiving space and is connected to the air passage. The air passage is configured to connect to an air bladder of the watch strap mechanism. The pressure sensor is disposed within the air passage.

[0008] The meter head mechanism provided in this application embodiment is provided with an air guide cover plate forming an air guide channel with the housing as at least part of the air path. By using the housing of the main body to form the air path, the number of parts of the air guide structure can be reduced, the installation space for installing the air guide structure can be reduced, the assembly can be made simpler, and the meter head mechanism is lighter and thinner.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0031] Currently, some wearable devices on the market measure users' blood pressure by using an airbag. These devices typically require one airbag. When in operation, the airbag inflates and presses against the skin. Pressure sensors detect pressure changes within the airbag, thereby measuring physiological parameters such as blood pressure and pulse. To inflate the airbag, an air pump and an air guiding structure are needed within the wearable device. The air guiding structure directs the airflow generated by the air pump into the airbag. Current air guiding structures often consist of multiple tubes, such as silicone tubes. Due to the small size of wearable devices and the presence of various other components within their internal space, interference with the air guiding structure is likely. This necessitates an obstacle avoidance design for the air guiding structure, resulting in numerous components and difficult assembly.

[0032] Based on this, the inventors of this application have proposed wearable devices according to various embodiments of this application, aiming to improve the above-mentioned deficiencies. The embodiments of this application are described in detail below with reference to the accompanying drawings.

[0033] Example

[0034] like Figure 1 As shown, this embodiment provides a wearable device 10, which is suitable for wearing on a user's wrist. The wearable device 10 can be, but is not limited to, a bracelet, a smartwatch, or other devices. This embodiment will use a smartwatch as an example to illustrate the wearable device 10.

[0035] Please refer to the following: Figure 1 and Figure 2 The wearable device 10 includes a main body 30, a strap 20, an inflation assembly 70, and a pressure sensor 60. The main body 30 can be used to house human-computer interaction devices such as a display screen 40. The strap 20 is connected to the main body 30 and is mainly used for wearing by the user. In this embodiment, the main body 30 is the watch face, and the strap 20 is the watch strap. In some embodiments of this application, a watch head mechanism is also provided, configured to connect with the watch strap mechanism. It is understood that the watch head mechanism can be part of the wearable device 10 described above. For example, the watch head mechanism may include the main body 30, and the watch strap mechanism may include the strap 20. The relevant features of the watch head mechanism and the watch strap mechanism can be referred to the relevant features of the wearable device 10.

[0036] Please see Figure 3 The main body 30 includes a middle frame 32 and a bottom shell 31. The bottom shell 31 is fitted onto the middle frame 32, forming a receiving space 38 between the bottom shell 31 and the middle frame 32. The receiving space 38 can be used to house the inflation assembly 70 and the pressure sensor 60. Specifically, as 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 generally rectangular frame structure. The bottom shell 31 is assembled to 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 mounting groove 323 can be used to mount the display screen 40. The display screen 40 can be used to display various information of the wearable device 10, such as time, weather, and other human-computer interaction information. In this embodiment, the display screen 40 can also be used to display measured physiological parameters. It is understood that 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 have a display screen 40; for example, a mechanical dial may be installed in the mounting slot 323. Two connecting portions 322 are connected to opposite ends of the body portion 321; specifically, the two connecting portions 322 are connected to the two ends of the body portion 321 along its length. The belt 20 is connected to the two connecting portions 322.

[0038] In some embodiments, the connecting portion 322 may also have a mounting opening facing downwards, allowing the belt 20 to connect to the main body 30 from the bottom surface (the side where the bottom shell 31 is located). In this embodiment, the connecting portion 322 is oriented downwards, allowing more space in the upper shell for mounting the display screen, for example, the display screen can be mounted on the entire upper shell. It is understood that when the mounting opening of the connecting portion 322 is located on the lower side of the main body 30, the relevant structure can refer to the embodiments in this application where it is located on the upper side (as shown in the relevant figures), and the orientation of the relevant structure can be adjusted accordingly.

[0039] In some embodiments, the connecting portion 322 may also be provided with a connector for connecting the strap 20, such as a hinge pin 326. The strap 20 may be an integral structure connected to the hinge pins 326 of the two connecting portions 322 of the main body 30. For example, the strap 20 may be made of an elastic material, allowing it to stretch and contract elastically during wear. In some embodiments, the strap 20 may include a first strap and a second strap. The first strap and the second strap may be respectively connected to the hinge pins 326 of the two connecting portions 322 of the main body 30, and the end of the first strap away from the main body 30 and the end of the second strap away from the main body 30 may be detachably connected, for example, by means of a buckle. The strap 20 may be made of materials such as metal, leather, fabric, plastic, or silicone; this embodiment does not limit the materials used.

[0040] The connecting part 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 passage in the receiving space 38, thereby inflating the airbag 75.

[0041] In some embodiments, during the connection of the belt 20 and the main body 30, the airbag 75 is simultaneously connected to the air passage, thereby achieving synchronous connection, which improves assembly efficiency and makes it more convenient for users.

[0042] In some embodiments, the inflation assembly 70 includes an air pump assembly 71, an airbag 75, and an air passage 35. The air pump assembly 71 is disposed on the main body 30 and communicates with the air passage 35. The airbag 75 is disposed on the belt body 20 and communicates with the air passage 35. The air pump assembly 71 is used to inflate the airbag 75. The airbag 75 is disposed on the belt body 20 and may be disposed on the surface of the belt body 20 facing the user's skin.

[0043] Figure 5 The disassembled structure of the inflatable assembly 70 is shown from a first-view perspective. Figure 6 The disassembled structure of the inflatable assembly 70 is shown from a second perspective; the first and second perspectives are opposite to each other. Please refer to the following in this embodiment. Figure 5 and Figure 6 The inflation assembly may also include a valve 72, which includes an air inlet 721 and a first air outlet 722. The air inlet 721 may be connected to the air pump assembly 71 to allow air to enter, and the first air outlet 722 may be connected to the airbag 75.

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

[0045] The air guide 712 connects the air inlet 721 and the air outlet 7111 of the air pump 711, thereby guiding the airflow pumped by the air pump 711 into the air inlet 721. In some embodiments, the air guide 712 may be, for example, an air pipe or other structure. In this embodiment, please continue reading... Figure 5 and Figure 6The air guide component 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. An air guide groove 717 is formed on the surface of the first cover plate 713 facing the second cover plate 714. The first cover plate 713 has a first through hole 715 communicating with the air guide groove 717 and communicating with the air outlet 7111 of the air pump 711. The second cover plate 714 has a second through hole 716 communicating with the air guide groove 717 and an air inlet 721 communicating with the second through hole 716. When the air pump 711 is working, airflow is pumped out from the air outlet 7111. The airflow 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 dimensions of the first cover plate 713 and the second cover plate 714 can be roughly set to be equivalent to those of the air pump 711, and 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 furthest 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. Understandably, to improve the sealing performance of the connection between the air guide 712, the air pump 711, and the valve 72, sealing rings can be provided at the connection between the first through hole 715 and the air outlet 7111 of the air pump 711, and at the connection between the second through hole 716 and the air inlet 721. These sealing rings can be made of materials such as plastic or silicone.

[0046] Please refer to the following: Figure 7 and Figure 8 The main body 30 is also provided with an air passage 35, and a first air outlet 722 is connected to the air passage 35. The air passage 35 is used to inflate the airbag 75 with airflow when the inflation component is working. A pressure sensor 60 is disposed in the air passage 35. The pressure sensor 60 is used to detect the pressure of the airbag 75, and the wearable device 10 can obtain the user's physiological parameters based on the pressure value of the airbag 75.

[0047] In some embodiments, please refer to Figure 3 The main body 30 also includes an air guide cover 365, which is disposed on the bottom shell 31 and forms a closed air guide channel 338 between the air guide cover 365 and the bottom shell 31. Figure 11 As shown in the diagram, the air guide channel 338 is formed between the air guide cover plate 365 and the bottom shell 31. The air guide channel 338 is formed using the bottom shell 31. The air guide channel 338 serves as at least a part of the air passage 35, eliminating the need for additional components such as air pipes 354, thus reducing the number of parts in the air passage 35 and facilitating assembly. In this embodiment, the air passage 35 also includes an air chamber 350, which connects the first air outlet 722 and the air guide channel 338.

[0048] Understandably, 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 housing, a middle frame 32, and an air guide cover 365. In some embodiments, the housing may only include a bottom shell 31. In some embodiments, the housing may also include an upper shell (not shown), which may be assembled with the bottom shell 31 and may be used to mount a display screen. The middle frame 32 is assembled to the housing and forms a receiving space 38. An air passage 35 is provided in the receiving space 38. The air guide cover 365 is disposed in the receiving space 38 and forms an air guide channel 338 between it and the housing. The air guide channel 338 may be at least a part of the air passage 35. The air pump assembly 71 is disposed in the receiving space 38 and is connected to the air passage 35. The air passage 35 is configured to connect to the air bladder 75 of the watch strap mechanism for inflating the air bladder 75. The pressure sensor 60 is disposed in the air passage 35. Specifically, the structures of the main body 30, the air pump assembly 71, and the pressure sensor 60 can be referred to in the foregoing or the following descriptions, and will not be repeated here.

[0049] In this embodiment, the vent cover 365 can form a venting channel 338 with the bottom shell 31. In another embodiment, when the housing also includes an upper shell, the vent cover 365 can also form a venting channel 338 with the upper shell; this embodiment does not limit this. For example, the vent cover 365 can also be disposed on the side near the display screen and can form a closed venting channel with the upper shell.

[0050] Understandably, in this embodiment, please refer again. Figure 7 and Figure 8 The air passage 35 includes a housing 351, a cover 352, and a base plate 333. The housing 351 is mounted on the base plate 333, and the cover 352 is mounted on the end of the housing 351 away from the base plate 333. The housing 351, cover 352, and base plate 333 together form a closed air chamber 350. The base plate 333 has a generally planar plate structure, and the housing 351 has a generally hollow columnar structure. The cover 352 is provided with an air inlet 3522 and an air outlet 3521. Both the air inlet 3522 and the air outlet 3521 are connected to the receiving cavity inside the air chamber 350. Both the air inlet 3522 and the air outlet 3521 can be configured as generally columnar structures and protrude from the surface of the cover 352. During assembly, the pressure sensor 60 is pre-installed in a predetermined position on the base plate 333 and fixed to the base plate 333. Then, the outer shell 351 and the cover 352 are assembled by means of bonding to form a closed air chamber 350. The air inlet 3522 and the first air outlet 722 are connected by an 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. This embodiment does not limit this.

[0051] In this embodiment, please refer to Figure 9 , Figure 10 as well as Figure 11 A guide groove 3651 is provided on the side of the air guide cover 365 facing the bottom shell 31. The guide groove 3651 forms at least a part of the air guide channel 338. It can be understood that other spaces between the air guide cover 365 and the bottom shell 31 can also be part of the air guide channel 338. The guide groove 3651 is connected to the air outlet 3521 of the air chamber 350, thereby guiding the airflow from the first air outlet 722 into the air guide channel 338. By setting 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 within 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, thus avoiding noise.

[0052] The guide groove 3651 can be a strip groove, a rectangular groove, etc., and is not limited here. In this embodiment, the guide groove 3651 has a racetrack-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 fit better with the groove wall of the guide groove 3651, resulting in better sealing performance.

[0053] The air guide cover 365 also has a first connecting hole 3652 and a second connecting hole 3653. Both the first connecting hole 3652 and the second connecting hole 3653 are connected to the guide groove 3651. The first connecting hole 3652 is used to connect with the air pump assembly. In this embodiment, the first connecting hole 3652 connects to the air outlet 3521 of the air chamber 350 and then connects to the air pump assembly. The second connecting hole 3653 is used to connect with the air bag 75. In this embodiment, the second connecting hole 3653 connects to the air nozzle 327 and then connects to the air bag 75. During assembly, the air outlet 3521 is inserted into the first connecting hole 3652, the air nozzle 327 is inserted into the second connecting hole 3653, and the guide groove 3651 is set towards the bottom shell 31. The bottom shell 31 covers the guide groove 3651 and closes the guide groove 3651. At this time, the space between the air guide cover 365 and the bottom shell 31 forms an air guide channel 338. This configuration allows for full utilization of the space between the air guide cover 365 and the bottom shell 31 for air guidance, making reasonable use of space while reducing the number of parts; and during assembly, only the air guide cover 365 needs to be assembled, resulting in higher assembly efficiency.

[0054] Furthermore, the first connecting hole 3652 and the second connecting hole 3653 penetrate the surface of the air guide cover 365 away from the bottom shell 31. During assembly, the air outlet 3521 and the air nozzle 327 are inserted into the surface of the bottom shell 31 of the air guide cover 365 and communicate with the guide groove 3651, facilitating overall assembly. It is understood that the first connecting hole 3652 and the second connecting hole 3653 can also penetrate other surfaces of the air guide cover 365, as long as the air outlet 3521 and the air nozzle 327 can be easily inserted into the first connecting hole 3652 and the second connecting hole 3653.

[0055] In some embodiments, for the meter mechanism, the air guide cover 365 may have a guide groove 3651 on the surface facing the bottom shell 31. The air guide cover 365 has a first connecting hole 3652 and a second connecting hole 3653. Both the first connecting hole 3652 and the second connecting hole 3653 are connected to the guide groove 3651. The first connecting hole 3652 is used to communicate with the air pump assembly 71, and the second connecting hole 3653 is used to communicate with the airbag 75. The bottom shell 31 and the guide groove 3651 constitute part of the air passage 35.

[0056] In other embodiments, for the meter mechanism, the air guide cover 365 may have a guide groove 3651 on the surface facing the upper shell. The air guide cover 365 has a first connecting hole 3652 and a second connecting hole 3653, both of which are connected to the guide groove 3651. The first connecting hole 3652 is used to communicate with the air pump assembly 71, and the second connecting hole 3653 is used to communicate with the airbag 75. The upper shell and the guide groove 3651 constitute part of the air passage 35.

[0057] In this embodiment, the air nozzle 327 also has a stepped surface 328, which is inclined relative to the axial direction of the air nozzle 327. The axial direction of the air nozzle 327 is approximately parallel to the axial direction of the air outlet 3521, which facilitates the air guiding channel 338. To better cooperate with the air nozzle 327, the air guide cover 365 is provided with an inclined surface 3654, in which the second connecting hole 3653 is opened. The inclined surface 3654 cooperates with the stepped surface 328, and the inclined surface 3654 can overlap the stepped surface 328, making the connection between the air guide cover 365 and the air nozzle 327 more stable.

[0058] Please refer to it again. Figure 2The wearable device 10 may also include a control unit 50, which may be disposed within 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 opening or closing of the first air outlet 722 of the air pump 711. Simultaneously, the control unit 50 may also be electrically connected to the pressure sensor 60 and acquire 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 user's blood pressure value based on the pressure information of the airbag 75 collected by the pressure sensor 60.

The CPU primarily handles the operating system, user interface, and applications; the GPU is responsible for rendering and drawing the displayed content; and the modem handles wireless communication. It is understood that the modem may also not be integrated into the processor and may be implemented separately through a communication chip.

[0060] The memory may include random access memory (RAM) or read-only memory (ROM). The memory can be used to store instructions, programs, code, code sets, or instruction sets. The memory may include a program storage area and a data storage area. The program storage area may store instructions for implementing an operating system, instructions for implementing at least one function (such as touch functionality, sound playback functionality, image playback functionality, etc.), and instructions for implementing the various method embodiments described below. The data storage area may also store data created during the use of the electronic device (such as phonebook data, audio and video data, chat log data, etc.). The control unit 50 executes the blood pressure measurement action by calling the instructions stored in the memory through the processor.

[0061] The wearable device 10 provided in this embodiment forms an air passage 338 between the air guide cover 365 and the bottom shell 31 as at least part of the air path 35. By using the bottom shell 31 of the main body 30 to form the air path 35, the number of parts of the air guide structure can be reduced, the installation space for installing the air guide structure can be reduced, the assembly can be made simpler, and the wearable device 10 is lighter and thinner.

[0062] Because of individual differences in body structure, a single airbag cannot accurately correspond to the area being measured during the measurement process, leading to errors in the measurement results. Therefore, this application provides a wearable device 10, including a main body 30, a strap 20, an inflation assembly 70, and a pressure sensor 60. The main body 30 has a first air passage 33 and a second air passage 34, and the strap 20 is connected to the main body 30. The inflation assembly 70 includes an air pump assembly 71, a valve 72, a first airbag 73, and a second airbag 74. The air pump assembly 71 is disposed in the main body 30. The valve 72 includes an air inlet 721, a first air outlet 722, and a second air outlet 723. The air inlet 721 is connected to the air pump, the first air outlet 722 is connected to the first air passage 33, and the second air outlet 723 is connected to the second air passage 34. The first airbag 73 is disposed in the strap 20 and connected to the first air passage 33, and the second airbag 74 is disposed in the strap 20 and connected to the second air passage 34. The pressure sensor 60 includes a first pressure sensor 60 and a second pressure sensor 60. The first pressure sensor 60 is disposed in the first air passage 33, and the second pressure sensor 60 is disposed in the second air passage 34.

[0063] In some embodiments, please refer to Figure 12 The inflation assembly 70 includes an air pump assembly 71, a valve 72, and an airbag 75 (not shown in the figure). See reference... Figure 13 The airbag 75 includes a first airbag 73 and a second airbag 74. The air pump assembly 71 can inflate the first airbag 73 and the second airbag 74 through the valve 72. The first airbag 73 and the second airbag 74 are disposed on the belt body 20, specifically on the surface of the belt body 20 facing the user's skin. This embodiment does not limit the arrangement of the first airbag 73 and the second airbag 74. As an example only, the first airbag 73 and the second airbag 74 can be arranged side-by-side along the width direction of the belt body 20. It is understood that in other embodiments, the first airbag 73 and the second airbag 74 can also be arranged in other ways, such as overlapping. The volume and material of the first airbag 73 and the second airbag 74 can be the same or different; this embodiment does not limit this.

[0064] Figure 14 The disassembled structure of the inflation assembly 70 in this embodiment is shown from a first-view perspective. Figure 15The disassembled structure of the inflatable assembly 70 is shown from a second perspective; the first and second perspectives are opposite to each other. Please refer to the following in this embodiment. Figure 14 and Figure 15 Valve 72 is a three-way valve, comprising an air inlet 721, a first air outlet 722, and a second air outlet 723. The air inlet 721 can be connected to the air pump assembly 71 for air intake, while the first air outlet 722 and the second air outlet 723 can be connected to the first airbag 73 and the second airbag 74, respectively. The connection status of the first air outlet 722 and the second air outlet 723 can be independently controlled. For example, the first air outlet 722 and the second air outlet 723 can be simultaneously connected to the air inlet 721, or they can be connected to the air inlet 721 individually. That is, when the first air outlet 722 is connected to the air inlet 721, the second air outlet 723 is disconnected from the air inlet 721; when the second air outlet 723 is connected to the air inlet 721, the first air outlet 722 is disconnected from the air inlet 721.

[0065] In this embodiment, the arrangement of the air inlet 721, the first air outlet 722, and the second air outlet 723 is not limited. Depending on the installation space requirements, the air inlet 721, the first air outlet 722, and the second air outlet 723 can be arranged in any manner. As a more specific implementation, to facilitate the connection between the valve 72 and the first air passage 33 ( Figure 7 (shown in the image) and the second air passage 34 ( Figure 7 (As shown in the diagram) The valve 72 is connected to the first air passage 33 and the second air passage 34, facilitating their layout. The first air outlet 722 and the second air outlet 723 can be located on opposite sides of the valve 72, and the axial directions of the first air outlet 722 and the second air outlet 723 can be parallel to each other. Specifically, the axial directions of the first air outlet 722 and the second air outlet 723 can also be coaxial. 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 both the axial directions of the first air outlet 722 and the second air outlet 723. This layout facilitates the arrangement of the air pump assembly 71 and avoids interference with other components.

[0066] Please refer to the following: Figure 16 and Figure 17 In this embodiment, the air passage 35 includes a first air passage 33 and a second air passage 34. The first air outlet 722 is connected to the first air passage 33, and the second air outlet 723 is connected to the second air passage 34. The first air passage 33 and the second air passage 34 are used to fill the first airbag 73 and the second airbag 74 with airflow when the inflation component 70 is working.

[0067] The pressure sensor 60 includes a first pressure sensor 61 and a second pressure sensor 62. The first pressure sensor 61 is disposed within the first air passage 33, and the second pressure sensor 62 is disposed within the second air passage 34. The first pressure sensor 61 is used to detect the pressure of the first airbag 73, and the second pressure sensor 62 is used to detect the pressure of the second airbag 74. Therefore, the wearable device 10 can obtain the user's physiological parameters based on the obtained pressure of the first airbag 73 and / or the second airbag 74.

[0068] The first air passage 33 and the second air passage 34 can be housed within the receiving space 38, thus avoiding exposed pipes and ensuring the overall appearance consistency of the main body 30, resulting in a more aesthetically pleasing design. In this embodiment, to facilitate the installation of the pressure sensor 60 and its assembly with components such as the air pump 711 and valve 72, the air guide cover 365 includes a first air guide cover 335 and a second air guide cover 345, such as... Figure 18 As shown, the first air guide cover 335 is disposed within the receiving space 38 and forms a first air guide channel 336 between itself and the bottom shell 31. The first air guide channel 336 serves as at least a part of the first air passage 33; as Figure 19 As shown, the second air guide cover 345 is disposed in the receiving space 38 and forms a second air guide channel 337 between it and the bottom shell 31. The second air guide channel 337 serves as at least a part of the second air passage 34.

[0069] The structure of the first air guide cover 335 and the second air guide cover 345 is the same as that of the air guide cover 365 in the previous embodiment. For details, please refer to the content of the previous embodiment. This embodiment will not repeat the description.

[0070] The first air passage 33 includes a first air chamber 330 and a first air guide channel 336 formed in the bottom shell 31. Figure 10 As shown in the figure, the first air chamber 330 can be a generally closed cavity structure. The second air passage 34 includes a second air chamber 340 and a second air guide channel 337 formed in the bottom shell 31. The second air chamber 340 can also be a generally closed cavity structure.

[0071] Specifically, in this embodiment, please continue to refer to... Figure 17The first air passage 33 includes a first outer shell 331 and a first cover 332. The first outer shell 331 is mounted on a base plate 333, and the first cover 332 is mounted on the end of the first outer shell 331 away from the base plate 333. The first outer shell 331, the first cover 332, and the base plate 333 enclose a closed first air chamber 330. The base plate 333 has a generally planar plate structure, and the first outer shell 331 has a generally hollow columnar structure. The first cover 332 is provided with an air inlet 3322 and an air outlet 3321. Both the air inlet 3322 and the air outlet 3321 are connected to the receiving cavity inside the first air chamber 330. Both the air inlet 3322 and the air outlet 3321 can be configured as generally columnar structures and protrude from the surface of the first cover 332. During assembly, the first pressure sensor 61 is pre-installed in a predetermined position on the base plate 333 and fixed to the base plate 333. Then, the first outer shell 331 and the first cover 332 are assembled by means of bonding to form a closed first air chamber 330. The air inlet 3321 and the first air outlet 722 are connected by a first air pipe 334, so that the first air outlet 722 is connected to the first air chamber 330. The first air pipe 334 can be configured into any shape according to the space between the first air chamber 330 and the first air outlet 722. This embodiment does not limit this.

[0072] The first connecting hole 3652 of the first air guide cover 335 connects to the air outlet 3321 of the first air chamber 330, so that the first air guide channel 336 connects to the air outlet 3321 of the first air chamber 330. In this embodiment, please continue to refer to... Figure 18 The first air guide cover 335 is disposed on the bottom shell 31 and forms a closed first air guide channel 336 between the bottom shell 31. That is, the first air guide channel 336 is formed between the first air guide cover 335 and the bottom shell 31. The first air guide channel 336 is formed by using the bottom shell 31, and there is no need to add other air pipes or other components.

[0073] In this embodiment, please refer again. Figure 14 and Figure 15The second air passage 34 includes a second outer shell 341 and a second cover 342. The second outer shell 341 is mounted on a base plate 333, and the second cover 342 is mounted on the end of the second outer shell 341 away from the base plate 333. The second outer shell 341, the second cover 342, and the base plate 333 together form a closed second air chamber 340. The base plate 333 has a generally planar plate structure, and the second outer shell 341 has a generally hollow columnar structure. The second cover 342 is provided with an air inlet 3422 and an air outlet 3421. Both the air inlet 3422 and the air outlet 3421 are connected to the receiving cavity inside the second air chamber 340. Both the air inlet 3422 and the air outlet 3421 can be configured as generally columnar structures and protrude from the surface of the second cover 342. During assembly, the second pressure sensor 62 is pre-installed in a predetermined position on the base plate 333 and fixed to the base plate 333. Then, the second housing 341 and the second cover 342 are assembled to form a closed second air chamber 340. The air inlet 3422 and the second air outlet 723 are connected by a second air pipe 344, so that the second air outlet 723 is connected to the second air chamber 340. 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. This embodiment does not limit this.

[0074] Please refer to it again. Figure 19 The first connecting hole 3652 of the second air guide cover 345 connects 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. 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 Figure 19 The second air guide cover 345 is disposed on the bottom shell 31 and forms a closed second air guide channel 337 between the bottom shell 31. That is, the second air guide channel 337 is formed between the second air guide cover 345 and the bottom shell 31. The second air guide channel 337 is formed by using the bottom shell 31, and no additional air pipes or other components are required.

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

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

[0078] The first air nozzle 324 and the second air nozzle 325 can be integrally formed with the connecting portion 322, so that the first air nozzle 324 and the second air nozzle 325 are formed simultaneously during the formation of the main body 30. It is understood that in some other embodiments, the first air nozzle 324 and the second air nozzle 325 may not be provided, and other methods may be used to achieve the communication between the first airbag 73 and the first air guide channel 336, and between the second airbag 74 and the second air guide channel 337. For example, a through hole can be opened in the connecting portion 322, extending part of the airbag 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 in the connecting portion 322, and the second airbag 74 is connected to the second air nozzle 325 located in the connecting portion 322. With this arrangement, since the first and second air nozzles 324 and 325 can be integrally formed with the connecting portion 322, the first airbag 73 and 74 can be easily connected, assembled, and sealed with the first air nozzle 324 and second air nozzle 325 during assembly, thereby improving the assembly efficiency of the wearable device 10. Simultaneously, since both the first and second airbags 73 and 74 are located outside the main body 30, they will not be interfered with by the main body 30 during inflation, improving both the safety of the inflation process and measurement accuracy.

[0080] Using the wearable device 10 provided in the above embodiments, blood pressure can be measured for a user. As an example only, the measurement method can be performed as follows:

[0081] When the user wears the wearable device 10 on their wrist, in response to the user's measurement command, the air pump 711 is turned 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 inside the first airbag 73 is detected in real time by the first pressure sensor 61.

[0082] The measurement command refers to the instruction issued by the user to perform a blood pressure test, which instructs the wearable device 10 to perform a blood pressure measurement. The measurement command can be issued by operating the wearable device 10, for example, by setting physical or virtual buttons on the main body 30 of the wearable device 10. The user issues the measurement command by operating the physical or virtual buttons. In another embodiment, the wearable device 10 can also be connected to the user's mobile phone, tablet computer, or other devices wirelessly or via a wired connection. The user can send measurement commands to the wearable device 10 through the mobile phone, tablet computer, or other devices. When air is inflated into the first airbag 73, the first airbag 73 expands and presses against the user's wrist skin. The first pressure sensor 61 collects the air pressure value inside the first airbag 73 in real time and can determine the external pressure value on the user's skin. The external pressure value is equal to the pressure value of the first airbag 73.

[0083] During inflation, the air pressure inside the first airbag 73 gradually increases, thus increasing the pressure on the user's skin. This compresses the user's radial artery, causing a change in the pulse wave. When the air pressure inside the first airbag 73 reaches a certain threshold, the pulse wave disappears to 0. When the air pressure inside the first airbag 73 rises to the point where the pulse wave disappears, the current air pressure value inside the first airbag 73 is recorded as the systolic blood pressure value. The pulse wave can be measured by a pulse wave sensor installed within the main body 30, which will not be described in detail in this embodiment.

[0084] After obtaining the user's systolic blood pressure through the first airbag 73, the air pump 711 is turned off, and the first airbag 73 is deflated. When the air pressure drops to the maximum pulse wave value, the current external pressure value is recorded as the diastolic blood pressure value, at which point the blood pressure measurement is complete. It should be noted that systolic blood pressure, also known as "high pressure," represents the highest blood pressure, while diastolic blood pressure, also known as "low pressure," represents the lowest blood pressure.

[0085] After the first airbag 73 deflates, the control air pump 711 is turned on, the second air outlet 723 is opened, and the first air outlet 722 is closed, inflating the second airbag 74. The air pressure value inside the second airbag 74 is detected by the second pressure sensor 62. During inflation, the air pressure value inside the second airbag 74 gradually increases, and the pressure on the user's skin increases accordingly. At this time, the user's radial artery is compressed, and the pulse wave changes. When the air pressure value inside the second airbag 74 reaches a certain threshold, the pulse wave disappears to 0. When the air pressure value inside the second airbag 74 rises to the point where the pulse wave disappears, the current air pressure value inside the second airbag 74 is recorded as the systolic blood pressure value.

[0086] After obtaining the user's systolic pressure via the second airbag 74, the air pump 711 is turned off, and the second airbag 74 is deflated. When the pressure drops to the maximum pulse wave value, the current external pressure value is recorded as the diastolic pressure value, at which point the pressure measurement is complete.

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

[0088] The wearable device 10 provided in this embodiment forms a first air passage 336 between the first air guide cover 335 and the bottom shell 31 as at least a part of the first air path 33, and forms a second air passage 337 between the second air guide cover 345 and the bottom shell 31 as at least a part of the second air path 34. By using the bottom shell 31 of the main body 30 to form the air path 35, the number of parts of the air guide structure can be reduced, the installation space for installing the air guide structure can be reduced, the assembly can be made simpler, and the wearable device 10 is lighter and thinner.

[0089] Meanwhile, the wearable device 10 provided in this embodiment is equipped with a first airbag 73 and a second airbag 74. The inflation and deflation of the first airbag 73 and the second airbag 74 enable the measurement of the user's physiological parameters, significantly improving the accuracy of these measurements. Furthermore, since the inflation assembly 70 uses only one air pump assembly 71, and the inflation of the first airbag 73 and the second airbag 74 is controlled by a valve 72, there is no need to add an additional air pump 711, reducing the space occupied by the main body 30 and avoiding increasing its volume.

[0090] The “wearable device 10” used in this application embodiment includes, but is not limited to, means configured to receive / transmit communication signals via wired connections (such as via a Public Switched Telephone Network (PSTN), Digital Subscriber Line (DSL), digital cable, direct cable connection, and / or another data connection / network) and / or via a wireless interface (e.g., for cellular networks, Wireless Local Area Networks (WLAN), digital television networks such as DVB-H networks, satellite networks, AM-FM broadcast transmitters, and / or another communication terminal).

[0091] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
