Technical Field

[0001] The present application relates to the technical field of wearable devices, and in particular to a wearable device. Background Art

[0002] As people's pace of life accelerates, more and more people have abnormal blood pressure. Abnormal blood pressure can easily induce the occurrence of various diseases. It is particularly important to detect blood pressure immediately. Wrist sphygmomanometers have emerged. However, in existing wrist sphygmomanometers, the detection component of the sphygmomanometer is directly connected to the air nozzle of the airbag. During the assembly or disassembly of the compression belt that accommodates the airbag, it is very easy to cause the detection component to move and cause damage to the detection component. Summary of the invention

[0003] The present application provides a wearable device, which avoids the problem of internal components of the wearable device being damaged due to displacement of the compression band when assembling or disassembling the compression band, thereby improving the service life of the wearable device.

[0004] The wearable device provided in the present application includes a dial, a watch strap and a compression belt. The dial includes a frame, a bottom cover and a blood pressure measurement component. The frame is connected to the periphery of the bottom cover, and together with the bottom cover, encloses an inner cavity of the dial. The bottom cover is provided with an external plug-in interface, a fluid channel and an internal plug-in interface that are connected in sequence, and the external plug-in interface is closer to the frame than the internal plug-in interface. The blood pressure measurement component is accommodated in the inner cavity of the dial, and the air nozzle of the blood pressure measurement component is connected to the internal plug-in interface. The watch strap is connected to the frame, the compression belt is stacked with the watch strap, and the air nozzle of the compression belt is connected to the external plug-in interface.

[0005] In the wearable device shown in the present application, the air nozzle of the blood pressure measuring component is connected to the internal plug-in interface, and the air nozzle of the compression belt is connected to the external plug-in interface. The air nozzle of the blood pressure measuring component and the air nozzle of the compression belt are connected through a fluid channel, that is, the fluid channel separates the air nozzle of the compression belt from the air nozzle of the blood pressure measuring component. During the assembly or disassembly of the compression belt, the blood pressure measuring component will not be easily affected and displaced, thereby avoiding damage to the blood pressure measuring component when the compression belt moves, which is beneficial to improving the service life of the wearable device.

[0006] Moreover, in the wearable device shown in the present application, the external interface, fluid channel and internal interface are all integrated in the bottom cover of the dial, and there is no need to set a connecting pipeline in the inner cavity of the dial, which reduces the space occupied by the connecting pipeline in the inner cavity of the dial, is conducive to improving the space utilization rate of the inner cavity of the dial, realizing a lightweight design of the dial, and improving the exquisite appearance of the wearable device.

[0007] In addition, in the wearable device shown in the present application, the external interface is closer to the frame than the internal interface, that is, the external interface connected to the air nozzle of the compression belt is closer to the edge, and the air nozzle of the compression belt does not need to extend to directly below the blood pressure measurement component to be connected to the air nozzle of the blood pressure measurement component. This not only reduces the extension length of the compression belt under the dial, which is beneficial to reducing the overall thickness of the wearable device and realizing a lightweight design of the wearable device, but also makes the position setting between the compression belt and the blood pressure measurement component more flexible, and the arrangement of devices such as batteries and heart rate detection sensors located in the inner cavity of the dial is also more flexible, which is beneficial to improving the space utilization rate of the inner cavity of the dial and helps to realize a lightweight design of the dial.

[0008] Among them, the bottom cover is provided with an inner plug-in nozzle and an outer plug-in nozzle, the inner side of the inner plug-in nozzle forms an inner plug-in interface, and the inner side of the outer plug-in nozzle forms an outer plug-in interface. The air nozzle of the blood pressure measurement component is connected to the inner plug-in interface, which means that the air nozzle of the blood pressure measurement component and the inner plug-in nozzle are plugged into each other, that is, the air nozzle of the blood pressure measurement component is plugged into the inner plug-in interface, or the air nozzle of the blood pressure measurement component is sleeved into the inner plug-in nozzle. Similarly, the air nozzle of the compression belt is connected to the outer plug-in interface, which means that the air nozzle of the compression belt and the outer plug-in nozzle are plugged into each other, that is, the air nozzle of the compression belt is plugged into the outer plug-in interface, or the air nozzle of the compression belt is sleeved into the outer plug-in nozzle.

[0009] The compression belt includes a cuff, an air bag contained in the cuff, and an air nozzle connected to the air bag.

[0010] The airbag and the air nozzle are integrally formed, or the airbag and the air nozzle are assembled and formed.

[0011] In one embodiment, the cross-sectional area of ​​the fluid channel is equal to or greater than 1 mm 2 , so as to reduce the air resistance of the fluid channel, ensure the gas exchange rate between the air nozzle of the compression belt and the air nozzle of the blood pressure detection component, realize the rapid flow of gas between the air nozzle of the compression belt and the air nozzle of the blood pressure detection component, and improve the blood pressure detection efficiency of the wearable device.

[0012] In one embodiment, the dial further includes a top cover, which is fixed to a side of the frame away from the bottom cover.

[0013] The top cover may be a display screen, which includes a display surface away from the frame, and the display surface is used to display information such as time, icons or physiological parameters of the user.

[0014] In one embodiment, the bottom cover includes a top surface facing the inner cavity of the dial, the distance between the external interface and the top surface of the bottom cover forms a first distance range, and the distance between the internal interface and the top surface of the bottom cover forms a second distance range, and the second distance range partially overlaps with the first distance range or completely overlaps with the first distance range, that is, the external interface and the internal interface partially share or completely share the thickness distance of the bottom cover in the Z direction, that is, the external interface and the internal interface are relatively close in the Z direction, which is beneficial to reducing the distance between the compression belt and the blood pressure measurement component in the Z direction, and is beneficial to reducing the thickness of the bottom cover, thereby facilitating the realization of a lightweight design of the wearable device.

[0015] The width direction of the dial is the X direction, the length direction of the dial is the Y direction, the thickness direction of the dial is the Z direction, and the X direction, the Y direction and the Z direction are perpendicular to each other.

[0016] The Z direction is the direction from the top cover to the bottom cover of the dial.

[0017] The top surface of the bottom cover is parallel to the XY plane of the dial.

[0018] The distance between one end of the external plug-in interface and the top surface of the bottom cover forms one end point of the first distance range, and the distance between the other end of the external plug-in interface and the top surface of the bottom cover forms another end point of the first distance range.

[0019] The distance between one end of the inner plug-in interface and the top surface of the bottom cover forms one end point of the second distance range, and the distance between the other end of the inner plug-in interface and the top surface of the bottom cover forms another end point of the second distance range.

[0020] In one embodiment, a third distance range is formed between the fluid channel and the top surface of the bottom cover, and the third distance range is a combination of the first distance range and the second distance range, that is, the distance between any position of the fluid channel and the top surface of the bottom cover is always within the first distance range or the second distance range, so that the fluid channel always shares the thickness distance of the bottom cover with the external interface or the internal interface in the Z direction, that is, avoiding the fluid channel from occupying additional thickness distance of the bottom cover in the Z direction, which is beneficial to reducing the thickness of the bottom cover, and further conducive to realizing a lightweight design of the dial.

[0021] In one embodiment, the air nozzle of the blood pressure measurement assembly extends along the Z direction.

[0022] In one embodiment, the fluid channel is in an "I" shape, an "S" shape, an "L" shape or a "Z" shape.

[0023] In one embodiment, the bottom cover includes a main body and a first cover part. The periphery of the main body is connected to a frame. The first cover part is fixed to one side of the main body. The first cover part forms an internal plug-in interface and is jointly formed with the main body to form a fluid channel to simplify the formation process of the fluid channel, that is, to simplify the formation process of the bottom cover and reduce the preparation cost of the bottom cover.

[0024] The main body is made of plastic such as polycarbonate or metal materials such as stainless steel.

[0025] In one embodiment, the main body includes a top surface facing the inner cavity of the dial, the top surface of the main body partially protrudes to form a boss, the first cover is fixedly connected to the boss, and together with the boss, a fluid channel is formed.

[0026] In the wearable device shown in this embodiment, the boss formed by the local protrusion of the top surface of the main body and the first cover member together form a fluid channel, and only the local thickness of the bottom cover needs to be increased, rather than the overall thickness of the bottom cover, saving the manufacturing cost of the bottom cover. In addition, this design allows the compression band to be connected to the external plug-in interface at the edge of the watch, reducing the volume of the compression band superimposed on the bottom of the watch, which is conducive to the lightweight design of the wearable device.

[0027] The elastic moduli of the main body and the first covering member may be the same or different.

[0028] In one embodiment, the air nozzle of the blood pressure measurement component is plugged into the internal plug-in interface, and the elastic modulus of the air nozzle of the blood pressure measurement component is greater than the elastic modulus of the first cover. That is, the air nozzle of the blood pressure measurement component is made of a hard material, and the first cover is made of an elastic material, that is, the air nozzle of the blood pressure measurement component is made of a relatively hard material, and the first cover is made of a relatively soft material. When the air nozzle of the blood pressure measurement component is inserted into the internal plug-in interface, the first cover will be deformed under the extrusion of the air nozzle of the blood pressure measurement component and fit tightly with the air nozzle of the blood pressure measurement component, thereby ensuring the sealing between the air nozzle of the blood pressure measurement component and the first cover.

[0029] The first cover member is made of elastic materials such as silicone or TPU (Thermoplastic polyurethanes).

[0030] In one embodiment, the bottom cover also includes a second cover piece, which is fixed to the side of the main body away from the first cover piece, and the second cover piece forms an external plug-in interface, and the air nozzle of the compression belt is plugged into the external plug-in interface, and the elastic modulus of the air nozzle of the compression belt is greater than the elastic modulus of the second cover piece. That is, the air nozzle of the compression belt is made of a hard material, and the second cover piece is made of an elastic material, that is, the air nozzle of the compression belt is made of a relatively hard material, and the second cover piece is made of a relatively soft material. When the air nozzle of the compression belt is inserted into the external plug-in interface, the second cover piece will be deformed under the extrusion of the air nozzle of the compression belt and fit tightly with the air nozzle of the compression belt, thereby ensuring the sealing between the air nozzle of the compression belt and the second cover piece.

[0031] The second cover member is made of elastic materials such as silicone or TPU.

[0032] In one embodiment, the main body includes a bottom surface facing away from the inner cavity of the dial, the bottom surface of the main body is partially recessed to form an assembly groove, the groove wall of the assembly groove is partially protruded to form an external plug-in nozzle, the inner side of the external plug-in nozzle forms an external plug-in interface, the air nozzle of the compression belt is located in the assembly groove, and the external plug-in nozzle is plugged into the air nozzle of the compression belt, that is, the air nozzle of the compression belt is sleeved on the external plug-in nozzle to achieve the connection between the compression belt and the main body.

[0033] In addition, the elastic modulus of the main body is greater than the elastic modulus of the air nozzle of the compression band. That is, the main body is made of a hard material, while the air nozzle of the compression band is made of an elastic material, that is, the main body is made of a relatively hard material, while the air nozzle of the compression band is made of a relatively soft material. When the external plug-in nozzle is inserted into the air nozzle of the compression band, since the external plug-in nozzle is harder and the air nozzle of the compression band is softer, the air nozzle of the compression band will be deformed under the extrusion of the external plug-in nozzle and fit closely with the external plug-in nozzle, thereby ensuring the sealing between the external plug-in nozzle and the air nozzle of the compression band.

[0034] In one embodiment, the opening of the assembly groove is located on the bottom surface of the main body, the assembly groove is recessed from the bottom surface of the main body toward the top surface, and passes through the circumference of the main body, and the air nozzle of the compression belt is located in the assembly groove. At this time, the compression belt partially shares or completely shares the thickness distance of the main body in the Z direction to reduce the impact of the compression belt on the thickness of the wearable device.

[0035] In one embodiment, the bottom cover also includes a fixing member, which is fixed to the side of the compression band facing away from the main body and supports the compression band, which not only prevents the air nozzle of the compression band from falling off from the external plug-in nozzle, maintains the plug-in stability between the air nozzle of the compression band and the external plug-in nozzle, but also prevents the compression band from falling off from the assembly groove, thereby improving the connection stability between the compression band and the main body.

[0036] In one embodiment, the external plug nozzle is located between the top surface of the main body and the bottom surface of the main body, that is, the external plug nozzle completely shares the thickness distance of the main body in the Z direction, thereby reducing the influence of the existence of the external plug nozzle on the thickness of the bottom cover, and helping to achieve a lightweight design of the wearable device.

[0037] In one embodiment, a portion of the circumferential surface of the main body protrudes to form an external plug-in nozzle, the inner side of the external plug-in nozzle forms an external plug-in interface, and the air nozzle of the compression belt is sleeved on the external plug-in nozzle, that is, the external plug-in nozzle is plugged into the air nozzle of the compression belt. At this time, the compression belt does not occupy the bottom space of the bottom cover at all, and only partially or completely shares the thickness distance of the main body in the Z direction, so as to reduce the influence of the compression belt on the thickness of the wearable device, which is conducive to the lightweight design of the wearable device.

[0038] In addition, the elastic modulus of the air nozzle of the compression band is smaller than the elastic modulus of the main body. That is, the air nozzle of the compression band is made of elastic material, and the main body is made of hard material, that is, the air nozzle of the compression band is made of relatively soft material, and the main body is made of relatively hard material. When the external plug-in nozzle is inserted into the air nozzle of the compression band, since the external plug-in nozzle is harder and the air nozzle of the compression band is softer, the air nozzle of the compression band will be deformed under the extrusion of the external plug-in nozzle and fit tightly with the external plug-in nozzle, thereby ensuring the sealing between the external plug-in nozzle and the air nozzle of the compression band.

[0039] In one embodiment, the wearable device also includes a gas sensor, which is located in the fluid channel and fixed to the inner wall of the fluid channel to analyze the gas composition of the environment surrounding the wearable device when the wearable device measures blood pressure, thereby improving the functional diversity of the wearable device and enhancing the user experience.

[0040] In one embodiment, there are two external plug-in interfaces, two fluid channels, and two internal plug-in interfaces, the two external plug-in interfaces are respectively a first external plug-in interface and a second external plug-in interface, the two fluid channels are respectively a first fluid channel and a second fluid channel, the two internal plug-in interfaces are respectively a first internal plug-in interface and a second internal plug-in interface, the first external plug-in interface, the first fluid channel, and the first internal plug-in interface are sequentially connected, and the second external plug-in interface, the second fluid channel, and the second plug-in interface are sequentially connected;

[0041] The blood pressure measurement assembly includes an air pump and a pressure sensor, the air nozzle of the air pump is connected to the first internal plug-in interface, and the air nozzle of the pressure sensor is connected to the second internal plug-in interface;

[0042] The compression belt includes two air nozzles, one air nozzle is connected to the first external plug-in interface so that the air pump can deliver the pumped gas into the airbag of the compression belt through the first fluid channel, or the gas in the airbag of the compression belt enters the air pump through the first fluid channel and is discharged from the air pump, and the other air nozzle is connected to the second external plug-in interface so that the gas in the airbag of the compression belt can be delivered to the pressure sensor through the second fluid channel, so that the pressure sensor can sense the changes in air pressure in the airbag to achieve blood pressure measurement.

[0043] In this embodiment, the air nozzles of the pressure sensor and the air pump are connected to the air nozzle of the compression belt through two fluid channels respectively, instead of sharing one fluid channel. This not only improves the installation flexibility of the blood pressure measurement component in the inner cavity of the dial, but also avoids mutual interference in gas transmission between the pressure sensor, the air pump and the air bag of the compression belt, which is beneficial to improving the measurement sensitivity and accuracy of the blood pressure measurement component during the blood pressure measurement process.

[0044] In one embodiment, the frame or the bottom cover is provided with a vent hole, which connects the inner cavity of the dial and the outside of the dial, so that the air pump can inhale gas from the surrounding environment through the vent hole during blood pressure measurement and fill the gas into the air bag to measure blood pressure.

[0045] In one embodiment, the wearable device also includes a heart rate detection sensor. A mounting hole is provided in the middle of the bottom cover and is spaced apart from the internal plug-in interface. The heart rate detection sensor is accommodated in the inner cavity of the dial and is opposite to the mounting hole or at least partially accommodated in the mounting hole, so as to send a sensing signal through the mounting hole to achieve heart rate measurement of the user, improve the functional diversity of the wearable device, and enhance the user experience.

Among them, the rectangular parallelepiped structure described above includes a rectangular parallelepiped structure and a structure similar to a rectangular parallelepiped. The structure similar to a rectangular parallelepiped means that the outer surface of the rectangular parallelepiped can be partially concave or partially convex, and the shape description of the structure in the following text can be understood in the same way. It should be understood that in other embodiments, the dial 100 may also be cylindrical, frustum, cube or other special-shaped structures.

[0088] See also Figure 5 and Figure 6 . Figure 5 yes Figure 4 A schematic structural diagram of the frame 10 in the dial 100 is shown. Figure 6 yes Figure 5 The frame 10 is shown as a schematic diagram of the structure cut along the AA direction. It should be noted that in the drawings of this application, "cut along the AA direction" means cutting along the AA line and the plane where the arrows at both ends of the AA line are located, and the description of the drawings in the following text shall be understood in the same way.

[0089] The frame 10 is a roughly rectangular parallelepiped frame structure. The frame 10 includes a top surface 101 and a bottom surface 102 disposed opposite to each other and a peripheral surface 103 connected between the top surface 101 and the bottom surface 102. The bottom surface 102 of the frame 10 is partially recessed to form a first fixing groove 104. That is, the opening of the first fixing groove 104 is located at the bottom surface 102 of the frame 10, and the first fixing groove 104 is recessed from the bottom surface 102 of the frame 10 to the direction of the top surface 101.

[0090] The circumferential surface 103 includes a first circumferential surface 105 and a second circumferential surface 106 which are arranged opposite to each other, and a third circumferential surface 107 and a fourth circumferential surface 108 which are connected between the first circumferential surface 105 and the second circumferential surface 106, and the third circumferential surface 107 and the fourth circumferential surface 108 are arranged opposite to each other.

There are two first fixing ears 11, and the two first fixing ears 11 are arranged at intervals at both ends of the first circumferential surface 105 along the X-axis direction. In addition, the second circumferential surface 106 partially protrudes to form a second fixing ear (not shown), and the second fixing ear protrudes from the second circumferential surface 106 in a direction away from the first circumferential surface 105.

Among them, the top surface 301 of the bottom cover 30 is parallel to the XY plane. It should be understood that the periphery of the bottom cover 30 refers to the edge portion of the bottom cover 30, that is, the portion of the bottom cover 30 formed by the edge of the top surface 301 of the bottom cover 30, the peripheral surface 303 of the bottom cover 30, and the edge of the bottom surface 302 of the bottom cover 30.

In this embodiment, there are two external plug-in interfaces 305, two fluid channels 306 and two internal plug-in interfaces 307.

[0103] For ease of understanding, the following description is made by taking the first external plug-in interface 305, the first fluid channel 306 and the first internal plug-in interface 307 as examples. The external plug-in interface 305 mentioned below refers to the first external plug-in interface 305, the fluid channel 306 refers to the first fluid channel 306, and the internal plug-in interface 307 refers to the first internal plug-in interface 307. It should be understood that since the second external plug-in interface 305 and the first external plug-in interface 305 have substantially the same structure, the second fluid channel 306 and the first fluid channel 306 have substantially the same structure, and the second internal plug-in interface 307 and the first internal plug-in interface 307 have substantially the same structure, they will not be described repeatedly.

[0104] Specifically, the external plug-in interface 305 is located at the edge of the bottom cover 30. The external plug-in interface 305 extends along the Z direction, that is, the external plug-in interface 305 extends along the thickness direction of the bottom cover 30. That is, the extension direction of the external plug-in interface 305 is perpendicular to the XY plane, that is, the extension direction of the external plug-in interface 305 is perpendicular to the top surface 301 of the bottom cover 30. Among them, the external plug-in interface 305 is a hole-like structure that is roughly cylindrical, and the external plug-in interface 305 has a central axis O1. It should be understood that the external plug-in interface 305 can also be a hole-like structure in a rectangular parallelepiped or other shapes.

[0105] Next, in order to facilitate understanding of the structure of the bottom cover 30, the plane where the top surface 301 of the bottom cover 30 is located is defined as the zero point position in the Z direction, the direction upward from the top surface 301 of the bottom cover 30 is the Z+ direction, and the direction downward from the top surface 301 of the bottom cover 30 is the Z- direction. Among them, the top surface 301 of the bottom cover 30 is the reference surface when the bottom cover 30 is machined or assembled, that is, the top surface 301 of the bottom cover 30 is the positioning reference when the bottom cover 30 is machined or assembled, so as to determine the specific position of each part or component in the dial 100. It should be noted that the directional terms such as "upper" and "lower" used in the bottom cover 30 shown in this embodiment are mainly based on the attached Fig. 9 and Fig.10 The display orientation in the figure is used to illustrate the present invention, and it does not limit the orientation of the bottom cover 30 in the actual application scenario.

[0106] The distance between the external plug-in interface 305 and the top surface 301 of the bottom cover 30 forms a first distance range [Z 11 , Z 12 ]. The distance between one end of the external plug-in interface 305 and the top surface 301 of the bottom cover 30 forms the initial endpoint Z of the first distance range. 11 The distance between the other end of the external plug-in interface 305 and the top surface 301 of the bottom cover 30 forms the end point Z of the first distance range. 12 .

[0107] Specifically, the external plug-in interface 305 includes a lower port and an upper port that are arranged opposite to each other. The lower port and the upper port of the external plug-in interface 305 are respectively located on both sides of the top surface 301 of the bottom cover 30. The lower port of the external plug-in interface 305 is located below the top surface 301 of the bottom cover 30 and is connected to the outside of the bottom cover 30. The distance between the lower port of the external plug-in interface 305 and the top surface 301 of the bottom cover 30 is Z. 11 , that is, Z 11 It is equal to the Z coordinate value of the top surface 301 of the bottom cover 30 minus the Z coordinate value of the lower port of the external plug-in interface 305. 11 The upper port of the external plug-in interface 305 is located above the top surface 301 of the bottom cover 30 and is connected to the fluid channel 306. The distance between the upper port of the external plug-in interface 305 and the top surface 301 of the bottom cover 30 is Z 12 , that is, Z 12 It is equal to the Z coordinate value of the upper port of the external plug-in interface 305 minus the Z coordinate value of the top surface 301 of the bottom cover 30. 12 >0.

[0108] The internal plug-in interface 307 is spaced apart from the external plug-in interface 305. In this embodiment, the internal plug-in interface 307 is located in the middle of the bottom cover 30 and is spaced apart from the mounting hole 304. When the bottom cover 30 is connected to the frame 10, the internal plug-in interface 307 is away from the frame 10 relative to the external plug-in interface 305, that is, the external plug-in interface 305 is closer to the frame 10 relative to the internal plug-in interface 307.

[0109] Specifically, the inner plug-in interface 307 and the outer plug-in interface 305 extend in the same direction, both extending in the Z direction. That is, the inner plug-in interface 307 also extends in the thickness direction of the bottom cover, that is, the extension direction of the inner plug-in interface 307 is also perpendicular to the top surface 301 of the bottom cover 30, that is, the extension direction of the inner plug-in interface 307 is also perpendicular to the XY plane. Among them, the inner plug-in interface 307 is a hole-like structure that is roughly cylindrical, and the inner plug-in interface 307 has a central axis O2. It should be understood that the inner plug-in interface 307 can also be a hole-like structure in a rectangular parallelepiped shape or other shapes.

[0110] The distance between the inner interface 307 and the top surface 301 of the bottom cover 30 forms a second distance range [Z 21 , Z 22 ]. The distance between one end of the internal interface 307 and the top surface 301 of the bottom cover 30 forms the initial end point Z of the second distance range. 21 The distance between the other end of the plug-in interface 307 and the top surface 301 of the bottom cover 30 forms the end point Z of the second distance range. 22 .

[0111] Specifically, the internal plug-in interface 307 includes a lower port and an upper port that are arranged opposite to each other. The lower port and the upper port of the internal plug-in interface 307 are respectively located on both sides of the top surface 301 of the bottom cover 30. The lower port of the internal plug-in interface 307 is located below the top surface 301 of the bottom cover 30 and is connected to the inside of the bottom cover 30. The distance between the lower port of the internal plug-in interface 307 and the top surface 301 of the bottom cover 30 is Z. 21 , that is, Z 21 = is equal to the Z coordinate value of the top surface 301 of the bottom cover 30 minus the Z coordinate value of the lower port of the interpolation interface 307. 21 The upper port of the internal plug-in interface 307 is located above the top surface 301 of the bottom cover 30 and communicates with the fluid channel 306. The distance between the upper port of the internal plug-in interface 307 and the top surface 301 of the bottom cover 30 is Z 22 , that is, Z 22 It is equal to the Z coordinate value of the upper port of the interpolation interface 307 minus the Z coordinate value of the top surface 301 of the bottom cover 30. 22 >0.

[0112] In this embodiment, the second distance range [Z 21 , Z 22 ] and the first distance range [Z11 , Z 12 ] partially overlap. That is, along the direction from the central axis O1 of the external plug-in interface 305 to the central axis O2 of the internal plug-in interface 307, the external plug-in interface 305 and the internal plug-in interface 307 are partially stacked, that is, the external plug-in interface 305 and the internal plug-in interface 307 partially share the thickness distance of the bottom cover 30 in the Z direction. At this time, the external plug-in interface 305 and the internal plug-in interface 307 are relatively close in the Z direction, which can reduce the thickness distance of the bottom cover 30 occupied by the external plug-in interface 305 and the internal plug-in interface 307 in the Z direction, which is conducive to realizing the thinning of the bottom cover 30 in the Z direction, and helps to realize the light and thin design of the dial 100.

[0113] It should be understood that, in other embodiments, the second distance range [Z 21 , Z 22 ] and the first distance range [Z 11 , Z 12 ] can also completely overlap. At this time, the lower port of the external interface 305 can be flush with the lower port of the internal interface 307, and in the direction from the central axis O1 of the external interface 305 to the central axis O2 of the internal interface 307, the external interface 305 and the internal interface 307 are completely stacked, that is, the external interface 305 and the internal interface 307 completely share the thickness distance of the bottom cover 30 in the Z direction, that is, the external interface 305 and the internal interface 307 are completely flush in the Z direction, which minimizes the thickness distance of the bottom cover 30 occupied by the external interface 305 and the internal interface 307 in the Z direction, which helps to achieve a light and thin design of the dial 100.

[0114] The fluid channel 306 is connected between the external plug-in interface 305 and the internal plug-in interface 307. The fluid channel 306 is in a "Z" shape. It should be understood that in other embodiments, the fluid channel 306 can be in a "U" shape, an "S" shape, an "L" shape, or the like.

[0115] A third distance range [Z 31 , Z 32 Specifically, the fluid channel 306 includes a lower end surface and an upper end surface that are arranged opposite to each other. The lower end surface and the upper end surface of the fluid channel 306 are respectively located on both sides of the top surface 301 of the bottom cover 30. The lower end surface of the fluid channel 306 is located below the top surface 301 of the bottom cover 30. The distance between the lower end surface of the fluid channel 306 and the top surface 301 of the bottom cover 30 is Z. 31 , that is, Z 31 It is equal to the Z coordinate value of the top surface 301 of the bottom cover 30 minus the Z coordinate value of the lower end surface of the fluid channel 306. 31<0. The upper end surface of the fluid channel 306 is located above the top surface 301 of the bottom cover 30. The distance between the upper end surface of the fluid channel 306 and the top surface 301 of the bottom cover 30 is Z 32 , that is, Z 32 = is equal to the Z coordinate value of the upper end surface of the fluid channel 306 minus the Z coordinate value of the top surface 301 of the bottom cover 30. 32 >0.

[0116] In this embodiment, the third distance range [Z 31 , Z 32 ] is the second distance range [Z 21 , Z 22 ] and the first distance range [Z 11 , Z 12 ], that is, the distance between any position of the fluid channel 306 and the top surface 301 of the bottom cover 30 is always within the first distance range [Z 11 , Z 12 ] or the second distance range [Z 21 , Z 22 That is, along the direction from the central axis O1 of the external plug-in interface 305 to the central axis O2 of the internal plug-in interface 307, a part of the fluid channel 306 is stacked with the internal plug-in interface 307, and another part of the fluid channel 306 is stacked with the external plug-in interface 305, that is, the fluid channel 306, the internal plug-in interface 307 and the external plug-in interface 305 completely share the thickness distance of the bottom cover 30 in the Z direction, avoiding the additional occupation of the thickness distance of the bottom cover 30 in the Z direction due to the existence of the fluid channel 306, which is conducive to realizing the thinning of the thickness of the bottom cover 30 in the Z direction and realizing the light and thin design of the dial 100.

[0117] In one embodiment, the fluid channel 306 includes a first channel 3061, a second channel 3062b, and a third channel 3063 that are connected in sequence. The first channel 3061 extends along the XY plane and is connected to the upper port of the external plug-in interface 305. The second channel 3062b extends along the Z direction and is connected between the first channel 3061 and the third channel 3063. The third channel 3063 extends along the XY plane and is connected to the lower port of the internal plug-in interface 307. Specifically, the cross-sectional area of ​​the fluid channel 306 is greater than 1 mm 2 , so as to reduce the air resistance of the gas flowing in the fluid channel 306 and ensure the gas flow rate between the external plug-in interface 305 and the internal plug-in interface 307. The shape of the cross section of the fluid channel 306 includes but is not limited to circular, square or other special shapes.

Specifically, the external plug-in nozzle 310 is located between the top surface 311 and the bottom surface 312 of the main body 31, that is, the external plug-in nozzle 310 completely shares the thickness distance of the main body 31 in the Z direction, reducing the influence of the existence of the external plug-in nozzle 310 on the thickness of the bottom cover 30, so as to realize the light and thin design of the dial 100.

[0131] In this embodiment, since the second distance range [Z 21 , Z22 ] and the first distance range [Z 11 , Z 12 ] only partially overlap, that is, the lower end of the external plug interface 305 is not flush with the lower end of the internal plug interface 307. At this time, the external plug nozzle 310 protrudes from the bottom wall of the assembly groove 319, does not exceed the bottom surface 312 of the main body 31, and does not exceed the bottom surface 312b of the truncated cone 312a. Compared with the second distance range [Z 21 , Z 22 ] and the first distance range [Z 11 , Z 12 ] The embodiment completely overlaps with the embodiment. In the wearable device 1000 shown in this embodiment, along the Z direction, the length dimension of the external plug-in nozzle 310 is larger, and the area of ​​the outer peripheral surface of the external plug-in nozzle 310 is also larger.

[0132] In addition, the bottom wall of the assembly groove 319 is partially recessed to form a first fixing hole 3192. Specifically, the opening of the first fixing hole 3192 is located at the edge area of ​​the bottom wall of the assembly groove 319, and is spaced apart from the opening of the avoidance groove 3191. The first fixing hole 3192 is recessed from the bottom wall of the assembly groove 319 toward the top surface 311 of the main body 31. There are two first fixing holes 3192, which are spaced apart and located on opposite sides of the avoidance groove 3191.

[0133] See also Fig.11 , the first cover part 32 is located on one side of the main body 31 close to the top surface 311, and the first cover part 32 forms an internal plug-in interface 307. In this embodiment, there are two first cover parts 32, and the two first cover parts 32 are located on the same side of the main body 31. Specifically, one first cover part 32 forms a first internal plug-in interface 307, which is compatible with the first boss 314. The other first cover part 32 forms a second internal plug-in interface 307, which is compatible with the second boss 314. Among them, the structures of the two first cover parts 32 are basically the same.

[0134] See also Fig.15 , Fig.15 yes Fig.11 A schematic structural diagram of the first covering member 32 is shown.

[0135] The first covering member 32 includes a first covering portion 321 and a first plug-in portion 322 connected to the first covering portion 321. In the present embodiment, the first covering portion 321 is roughly in the form of a planar plate. The first covering portion 321 includes a top surface 323 and a bottom surface 324 disposed opposite to each other. The first plug-in portion 322 is connected to the bottom surface 324 of the first covering portion 321. The first plug-in portion 322 extends from the bottom surface 324 of the first covering portion 321 in a direction away from the top surface 323 and is roughly in the form of a circular tubular structure. The first plug-in portion 322 includes a bottom surface 325 facing the same direction as the bottom surface 324 of the first covering portion 321. The bottom surface 325 of the first plug-in portion 322 is partially recessed to form an internal plug-in interface 307, that is, the opening of the internal plug-in interface 307 is located at the bottom surface 325 of the first plug-in portion 322. The inner plug interface 307 extends from the bottom surface 325 of the first plug portion 322 toward the top surface 323 of the first cover portion 321 and penetrates the top surface 323 of the first cover portion 321. The first cover member 32 is made of elastic materials such as silicone or TPU.

[0136] See also Fig.16 , Fig.16 yes Fig.15 The structure diagram of the first covering member 32 is shown cut away along the EE direction.

[0137] The plug-in interface 307 includes an upper end portion 3071 and a lower end portion 3072 that are connected to each other. The upper end portion 3071 is close to the top surface 323 of the first covering portion 321. In the direction from the bottom surface 324 of the first covering portion 321 to the top surface 323, that is, in the Z direction shown in the figure, that is, in the thickness direction of the first covering portion 321, the inner diameter of the upper end portion 3071 gradually increases. That is, the upper end portion 3071 is a hole-shaped structure that is roughly horn-shaped. The lower end portion 3072 is located below the upper end portion 3071, and the lower end portion 3072 is a hole-shaped structure that is roughly cylindrical.

[0138] See also Fig. 9 The first cover part 32 is fixed to one side of the main body 31, and is jointly formed with the main body 31 to enclose a fluid channel 306, so as to simplify the forming process of the fluid channel 306, that is, to simplify the forming process of the bottom cover 30, and to reduce the preparation cost of the bottom cover 30. Among them, the material of the first cover part 32 is different from that of the main body 31, that is, the elastic modulus of the first cover part 32 is different from that of the main body 31. It should be understood that the material of the first cover part 32 can also be the same as that of the main body 31, that is, the elastic modulus of the first cover part 32 is the same as that of the main body 31. In this case, the first cover part 32 can also be integrally formed with the main body 31 to improve the structural strength of the bottom cover 30 and ensure the structural stability of the bottom cover 30.

[0139] In this embodiment, the first cover member 32 is fixedly connected to the boss 314, and together with the boss 314, forms a fluid channel 306. The first cover member 32 formed with a first internal plug-in interface 307 is fixedly connected to the first boss 314, and together with the first boss 314, forms a first fluid channel 306. The first cover member 32 formed with a second internal plug-in interface 307 is fixedly connected to the second boss 314, and together with the second boss 314, forms a second fluid channel 306.

[0140] In the wearable device 1000 shown in this embodiment, the boss 314 formed by the local protrusion of the top surface 323 of the main body 31 and the first cover part 32 together form a fluid channel 306. It is only necessary to increase the local thickness of the bottom cover 30 instead of increasing the overall thickness of the bottom cover 30, thereby saving the preparation cost of the bottom cover 30.

[0141] Next, the assembly structure between the first cover member 32 and the boss 314 is described by taking the first cover member 32 and the first boss 314 formed with the first internal plug-in interface 307 as an example. It should be understood that the assembly structure between the first cover member 32 and the second boss 314 formed with the second internal plug-in interface 307 is substantially the same as the assembly structure between the first cover member 32 and the first boss 314 formed with the first internal plug-in interface 307, and will not be described again in the following text.

[0142] Please also read Fig.13 , the first covering member 32 is fixedly mounted on the first mounting groove 316. The first covering portion 321 is fixedly mounted on the first groove body 3161 of the first mounting groove 316. The first covering portion 321 covers the openings of the first portion 3171 and the second portion 3172 of the fluid groove 317 to form the first channel 3061 of the fluid channel 306. The first plug-in portion 322 extends from the first groove body 3161 into the second groove body 3162 to connect the internal interface 307 with the third portion 3173 of the fluid groove 317. The first plug-in portion 322 fits with the groove side wall of the second groove body 3162 and covers the opening of the second portion 3172 of the fluid groove 317 on the groove side wall of the second groove body 3162 to form the second channel 3062 of the fluid channel 306. The first plug-in portion 322 also covers the opening of the third portion 3173 of the fluid groove 317 to form the third channel 3063 of the fluid channel 306.

[0143] See also Fig.11, the fixing member 33 is located on the side of the main body 31 away from the first covering member 32, that is, the fixing member 33 is located on the side of the main body 31 close to the bottom surface 312. The fixing member 33 is a plate-like structure adapted to the shape of the assembly groove 319. The fixing member 33 includes a top surface 331 and a bottom surface 332 that are arranged opposite to each other. The bottom surface 332 of the fixing member 33 is partially recessed to form a second fixing hole 333, that is, the opening of the second fixing hole 333 is located on the bottom surface 332 of the fixing member 33. The second fixing hole 333 extends from the bottom surface 332 of the fixing member 33 to the direction of the top surface 331, and passes through the top surface 331 of the fixing member 33, that is, the second fixing hole 333 passes through the fixing member 33 along the thickness direction of the fixing member 33. Among them, there are two second fixing holes 333, and the two second fixing holes 333 are arranged at intervals on the edge of the fixing member 33.

[0144] See also Fig.14 and Fig.17 , Fig.17 yes Fig.11 The schematic diagram of the assembly structure of the fixing member 33 and the main body 31 in the bottom cover 30 is shown.

[0145] The fixing member 33 is fixed to the side of the main body 31 away from the first cover member 32. That is, the first cover member 32 and the fixing member 33 are respectively fixed to the opposite sides of the main body 31, and when the wearable device 1000 is worn by the user, the fixing member 33 is placed toward the user's wrist, and the first cover member 32 is placed away from the user's wrist.

[0146] Specifically, the fixing member 33 is fixedly installed in the assembly groove 319. The fixing member 33 can be installed in a detachable manner by fasteners such as screws or bolts passing through the second fixing hole 333 and locking in the first fixing hole 3192. At this time, the fixing member 33 covers the opening of the assembly groove 319, and covers the avoidance groove 3191 and the external plug-in nozzle 310. In addition, the bottom surface 332 of the fixing member 33 is flush with the bottom surface 332 of the main body 31, that is, the bottom surface 332 of the fixing member 33 and the bottom surface 332 of the main body 31 are located in the same plane, so that when the wearable device 1000 is worn by the user, the connection between the bottom surface 332 of the fixing member 33 and the bottom surface 332 of the main body 31 will not be partially protruded and press against the user's wrist, thereby improving the user's experience.

[0147] See also Figure 4 and Fig.18 , Fig.18 yes Figure 3 The structure diagram of the dial 100 shown is cut away along the FF direction.

[0148] The periphery of the main body 31 is connected to the frame 10, and together with the frame 10 and the top cover 20, the dial cavity 110 is enclosed. At this time, the top surface 311 of the main body 31 faces the dial cavity 110, that is, the boss 314 is located in the dial cavity 110. The first cover member 32 is located in the dial cavity 110, and the fixing member 33 is located outside the dial 100. Among them, the first cover member 32 and the boss 314 are both located in the dial cavity 110, which fully utilizes the volume of the dial cavity 110 to form the fluid channel 306 without increasing the volume outside the dial 100, which is conducive to the light and thin design of the dial 100.

[0149] The processor is housed in the inner cavity 110 of the dial. The processor may include one or more processing units, for example: the processing unit may include an application processor (AP), a modem processor, a graphics processor (GPU), an image signal processor (ISP), a controller, a memory, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural network processor (NPU). Among them, different processing units may be independent devices or integrated in one or more processors. Among them, the processor may be the nerve center and command center of the wearable device 1000. The processor may generate an operation control signal according to the instruction opcode and the timing signal to complete the control of fetching and executing instructions. In addition, the processor may also include a storage unit for storing instructions and data. For example, the storage unit of the processor is a high-speed cache memory. The memory may store instructions or data that the processor has just used or circulated. If the processor needs to use the instruction or data again, it can be directly called from the memory, avoiding repeated access, reducing the waiting time of the processor, and thus improving the efficiency of the system.

[0150] The blood pressure measurement component 40 is electrically connected to the processor. In the present embodiment, the blood pressure measurement component 40 includes an air pump 41 and a pressure sensor 42. The air pump 41 is electrically connected to the processor to receive a control signal sent by the processor and to extract or discharge gas according to the control signal. The pressure sensor 42 is spaced apart from the air pump 41 and electrically connected to the processor to receive a control signal sent by the processor and to sense a pressure signal according to the control signal, and can convert the pressure signal into an electrical signal. Among them, the pressure sensor can be a capacitive pressure sensor. The capacitive pressure sensor includes at least two parallel plates with a conductive material. When a force acts on the pressure sensor, the capacitance between the electrodes changes. The processor determines the intensity of the pressure based on the change in the electrode capacitance. Of course, the pressure sensor 42 can also be a resistive pressure sensor or an inductive pressure sensor pressure sensor, etc.

[0151] Specifically, the blood pressure measurement component 40 is located in the dial cavity 110, and the air nozzle 401 of the blood pressure measurement component 40 is connected to the internal plug-in interface 307. The air nozzle 401 of the air pump 41 is connected to the first internal plug-in interface 307, so that the air pump 41 can transfer the pumped gas from the vent 109 to the first fluid channel 306, or receive the gas transferred from the first fluid channel 306 and discharge the gas through the vent 109. The air nozzle 401 of the pressure sensor 42 is connected to the second internal plug-in interface 307, so that the pressure sensor 42 can sense the air pressure change through the second fluid channel 306 to measure the blood pressure.

[0152] Next, taking the air nozzle 401 of the air pump 41 as an example, the assembly structure between the air nozzle 401 of the blood pressure measurement component 40 and the plug-in interface 307 is described. Among them, the air nozzle 401 of the blood pressure measurement component 40 mentioned below refers to the air nozzle 401 of the air pump 41, and the plug-in interface 307 refers to the first plug-in interface 307 that is connected to the air nozzle 401 of the air pump 41. It should be noted that the assembly structure between the air nozzle 402 of the pressure sensor 42 and the second plug-in interface 307 is roughly the same as the assembly structure between the air nozzle 401 of the air pump 41 and the first plug-in interface 307, and will not be repeated in the following text.

[0153] In this embodiment, the air nozzle 401 of the blood pressure measurement component 40 is plugged into the internal plug-in interface 307 and extends along the Z direction. The air nozzle 401 of the blood pressure measurement component 40 is plugged into the internal plug-in interface 307 from the upper end of the internal plug-in interface 307. Along the Z direction, since the inner diameter of the upper end of the internal plug-in interface 307 gradually increases, the air nozzle 401 of the blood pressure measurement component 40 can be more easily plugged into the internal plug-in interface 307. In addition, the inner diameter of the lower end of the internal plug-in interface 307 is equal to or slightly smaller than the outer diameter of the air nozzle 401 of the blood pressure measurement component 40, so as to ensure that when the air nozzle 401 of the blood pressure measurement component 40 extends from the upper end of the internal plug-in interface 307 into the lower end, the air nozzle 401 of the blood pressure measurement component 40 is tightly fitted with the first cover 32, thereby ensuring the connection reliability between the air nozzle 401 of the blood pressure measurement component 40 and the first cover 32.

[0154] It should be understood that, in other embodiments, the inner plug interface 307 may be formed in the same manner as the outer plug interface 305. At this time, the top surface 323 of the first cover portion 321 partially protrudes to form an inner plug nozzle, and the inner side of the inner plug nozzle forms the inner plug interface 307. The air nozzle 401 of the blood pressure measurement component 40 and the inner plug nozzle are plugged into each other, that is, the air nozzle 401 of the blood pressure measurement component 40 is plugged into the inner plug interface 307, or the air nozzle 401 of the blood pressure measurement component 40 is sleeved into the inner plug nozzle.

[0155] In one embodiment, the elastic modulus of the air nozzle 401 of the blood pressure measurement component 40 is greater than the elastic modulus of the first cover 32. That is, the air nozzle 401 of the blood pressure measurement component 40 is made of a hard material, and the first cover 32 is made of an elastic material, that is, the air nozzle 401 of the blood pressure measurement component 40 is made of a relatively hard material, and the first cover 32 is made of a relatively soft material. When the air nozzle 401 of the blood pressure measurement component 40 is inserted into the internal plug interface 307, the first cover 32 will be deformed under the extrusion of the air nozzle 401 of the blood pressure measurement component 40 and fit closely with the air nozzle 401 of the blood pressure measurement component 40, thereby ensuring the sealing between the air nozzle 401 of the blood pressure measurement component 40 and the first cover 32. It should be understood that the air nozzle 401 of the blood pressure measurement component 40 and the first cover 32 can also be sealed by a sealing ring or a sealing pad and other structures, and this application does not specifically limit this.

[0156] The sensor assembly is spaced apart from the blood pressure measurement assembly 40 and is electrically connected to the processor. Specifically, the sensor assembly includes a heart rate detection sensor, which is opposite to the mounting hole (not shown) or at least partially accommodated in the mounting hole. Among them, the heart rate detection sensor is an optical heart rate sensor. When the wearable device 100 is worn by the user, the bottom surface 312b of the boss 312a fits the user's wrist, and the optical heart rate sensor can send a heart rate sensing signal through the mounting hole to achieve accurate detection of the heart rate, improve the functional diversity of the wearable device 1000, and enhance the user's experience. Of course, the heart rate detection sensor can also be a bone conduction sensor or other sensor that can perform heart rate detection.

[0157] In addition, the sensor component may also include sensors such as a gyroscope sensor, an air pressure sensor, an acceleration sensor, a distance sensor, a proximity light sensor, a fingerprint sensor, a temperature sensor or an ambient light sensor to further improve the functional diversity of the wearable device 1000 and enhance the user experience.

[0158] See also Figure 2 and Fig.19 , Fig.19 yes Figure 2 A schematic structural diagram of the compression band 300 in the wearable device 1000 is shown.

[0159] The compression belt 300 is located on one side of the dial 100. The compression belt 300 includes a cuff 320, an air bag (not shown) contained in the cuff 320, and an air nozzle 340 connected to the air bag. The cuff 320 includes a top surface 320a and a bottom surface 320b arranged opposite to each other, and a peripheral surface 320c connected between the top surface 320a and the bottom surface 320b. The air bag is located at a position of the cuff 320 close to the dial 100. The air nozzle 340 protrudes from the top surface 320a of the cuff 320. The air nozzle 340 extends from the top surface 320a of the cuff 320 in a direction away from the bottom surface 320b, that is, the air nozzle 340 extends along the Z direction. Among them, the air nozzle 340 can be made of the same material as the air bag, in which case the air nozzle 340 can be integrally formed with the air bag. Alternatively, the air nozzle 340 and the air bag can also be made of different materials, in which case the air nozzle 340 can be detachably assembled with the air bag.

[0160] In this embodiment, there are two air nozzles 340. The two air nozzles 340 are respectively a first air nozzle 340 and a second air nozzle 340. The first air nozzle 340 and the second air nozzle 340 are spaced apart along the X direction. The structures of the first air nozzle 340 and the second air nozzle 340 are substantially the same.

[0161] See also Fig. 20 and Fig.21a . Fig. 20 yes Figure 2A schematic diagram of the assembly structure of the compression band 300 and the dial 100 in the wearable device 1000 is shown. Fig.21a yes Fig. 20 The structure shown is a schematic diagram of the structure cut along the GG direction. Fig. 20 and Fig.21a Only the portion where the compression band 300 is connected to the dial 100 is shown.

[0162] The compression belt 300 partially extends into the assembly groove 319 and is fixed in the assembly groove 319, and partially extends out of the assembly groove 319. At this time, the compression belt 300 completely shares the thickness distance of the bottom cover 30 in the Z direction, which reduces the influence of the compression belt 300 on the thickness of the wearable device 1000 when it is assembled on the bottom cover 30, and helps to realize the lightweight design of the wearable device 1000.

[0163] The air nozzle 340 of the compression belt 300 is located in the assembly groove 319. Specifically, the air nozzle 340 of the compression belt 300 is connected to the external plug-in interface 305. That is, the air nozzle 340 of the compression belt 300 is connected to the air nozzle 401 of the blood pressure measurement component 40 through the fluid channel 306. At this time, the air bag 330 of the compression belt 300 is connected to the external plug-in interface 305 through the air nozzle 340. That is, the air bag 330 of the compression belt 300 is connected to the air nozzle 401 of the blood pressure measurement component 40 through the air nozzle 340 of the compression belt 300 and the fluid channel 305.

[0164] Since the cross-sectional area of ​​the fluid channel 306 is equal to or greater than 1 mm 2 That is, the inner diameter of the fluid channel 306 is large enough so that the gas flow resistance in the fluid channel 306 is small, ensuring that the gas exchange rate between the air nozzle 340 of the compression belt 300 and the air nozzle 401 of the blood pressure measurement component 40 is large enough, which helps to quickly circulate the gas between the air nozzle 340 of the compression belt 300 and the air nozzle 401 of the blood pressure measurement component 40, and is beneficial to improving the blood pressure detection efficiency of the wearable device 1000.

[0165] In the wearable device 1000 shown in this embodiment, the fluid channel 306 separates the air nozzle 340 of the compression band 300 from the air nozzle 401 of the blood pressure measurement component 40. During the assembly or disassembly of the compression band 300, the blood pressure measurement component 40 will not be easily affected and displaced, thereby avoiding damage to the blood pressure measurement component 40 when the compression band 300 moves, which is beneficial to improving the service life of the wearable device 1000.

[0166] Moreover, the external plug-in interface 305, the fluid channel 306 and the internal plug-in interface 307 are all integrated in the bottom cover 30 of the dial 100. There is no need to set a connecting pipeline between the air nozzle 340 of the compression belt 300 and the air nozzle 340 of the blood pressure measurement component 40 in the dial inner cavity 110, thereby avoiding the space occupancy rate of the connecting pipeline in the dial inner cavity 110, which is beneficial to improving the space utilization rate of the dial inner cavity 110, realizing the lightweight design of the dial 100, and improving the exquisite appearance of the wearable device 1000.

[0167] Furthermore, the external plug-in interface 305 connected to the air nozzle 340 of the compression belt 300 is closer to the frame 10, that is, the internal plug-in interface 307 connected to the air nozzle 401 of the blood pressure measurement component 40 is closer to the middle of the bottom cover 30, so that the air nozzle 340 of the compression belt 300 does not need to extend to the bottom of the blood pressure measurement component 40 to be connected to the air nozzle 401 of the blood pressure measurement component 40, which can not only reduce the extension length of the compression belt 300 under the dial 100, but also help to reduce the overall thickness of the wearable device 1000 and realize the lightweight design of the wearable device 1000, but also make the position design between the compression belt 300 and the blood pressure measurement component 40 more flexible, thereby making the position design of functional components such as the battery and / or sensor module located in the dial cavity 110 more flexible, which is beneficial to improve the space utilization of the dial cavity 110 and help to realize the lightweight design of the wearable device 1000.

[0168] See also Fig.21a and Figure 21b , Figure 21b yes Fig.21a Schematic diagram of the enlarged structure of the H region in the structure shown.

[0169] In this embodiment, the first air nozzle 340 of the compression belt 300 is connected to the first external plug-in interface 305. At this time, the first air nozzle 340 of the compression belt 300 is connected to the air nozzle 401 of the air pump 41 through the first fluid channel 306. When the wearable device 1000 needs to measure blood pressure, the air pump 41 can send the external air extracted through the vent 109 into the airbag 330 of the compression belt 300 through the first fluid channel 306 and the air nozzle 340 of the compression belt 300 to inflate the airbag 330 of the compression belt 300. When the blood pressure measurement of the wearable device 1000 is completed, the air in the airbag 330 of the compression belt 300 can be sent to the air pump 41 through the air nozzle 340 of the compression belt 300 and the first fluid channel 306, and the air pump 41 can discharge the gas through the vent 109. Among them, when the air pump 41 inflates the airbag 330, the flow path of the gas is as follows: Figure 21b As shown by the dashed arrow, when the gas in the airbag 330 is discharged by the air pump 41, the flow path of the gas is as follows: Figure 21b As shown by the solid arrow in the middle, the descriptions of the solid arrow and the dotted arrow in the following drawings shall be understood in the same way.

[0170] The second air nozzle 340 of the compression belt 300 is connected to the second external plug-in interface 305. At this time, the second air nozzle 340 of the compression belt 300 is connected to the air nozzle 401 of the pressure sensor 42 through the second fluid channel 306. The pressure sensor 42 can sense the air pressure value in the airbag 330 of the compression belt 300 through the second fluid channel 306.

[0171] In the wearable device 1000 shown in this embodiment, the air pump 41 and the air nozzle 401 of the pressure sensor 42 are connected to the air nozzle 340 of the compression belt 300 through two fluid channels 306 respectively, without sharing a fluid channel. This can not only improve the installation flexibility of the blood pressure measurement component 40 in the dial cavity 110, but also avoid mutual interference in gas transmission between the air pump 41 and the pressure sensor 42 and the air bag 330 of the compression belt 300, which is beneficial to improving the measurement sensitivity and accuracy of the blood pressure measurement component 40 during the blood pressure measurement process.

[0172] Next, the assembly structure between the first air nozzle 340 of the compression belt 30 and the first external plug-in nozzle 310 is described as an example. The air nozzle 340 of the compression belt 300 referred to below refers to the first air nozzle 340 of the compression belt 340, and the external plug-in nozzle 310 refers to the first external plug-in nozzle 310. It should be understood that the assembly structure between the second air nozzle 340 of the compression belt 300 and the second external plug-in nozzle 310 is basically the same as the assembly structure between the first air nozzle 340 and the first plug-in nozzle 310, and will not be described again below.

[0173] Specifically, the air nozzle 340 of the compression belt 300 is sleeved on the external plug-in nozzle 310, that is, the external plug-in nozzle 310 is plugged into the air nozzle 340 of the compression belt 300, so that the compression belt 300 and the bottom cover 30 are connected to each other. Among them, the inner diameter of the air nozzle 340 of the compression belt 300 is slightly smaller than the outer diameter of the external plug-in nozzle 310, so that when the air nozzle 340 of the compression belt 300 is sleeved on the external plug-in nozzle 310, that is, when the external plug-in nozzle 310 is plugged into the air nozzle 340 of the compression belt 300, the air nozzle 340 of the compression belt 300 can be closely fitted with the external plug-in nozzle 310, ensuring the reliability of the connection between the air nozzle 340 of the compression belt 300 and the external plug-in nozzle 310.

[0174] It can be understood that compared with the second distance range [Z 21 , Z 22 ] and the first distance range [Z 11 , Z 12] In the wearable device 1000 shown in this embodiment, since the length dimension of the external plug-in nozzle 310 is larger along the Z direction, the area of ​​the outer peripheral surface of the external plug-in nozzle 310 is also larger, and the contact area between the air nozzle 340 of the compression belt 300 and the external plug-in nozzle 310 is also larger, which not only increases the connection reliability between the air nozzle 340 of the compression belt 300 and the external plug-in nozzle 310, but also reduces the risk of air leakage between the air nozzle 340 of the compression belt 300 and the external plug-in nozzle 310.

[0175] In one embodiment, the elastic modulus of the main body 31 is greater than the elastic modulus of the air nozzle 340 of the compression band 300. That is, the main body 31 is made of a hard material, while the air nozzle 340 of the compression band 300 is made of an elastic material. That is, the outer plug-in nozzle 310 of the main body 31 is made of a relatively hard material, while the air nozzle 340 of the compression band 300 is made of a relatively soft material. When the outer plug-in nozzle 310 is inserted into the air nozzle 340 of the compression band 300, since the outer plug-in nozzle 310 is harder and the air nozzle 340 of the compression band 300 is softer, the air nozzle 340 of the compression band 300 will be deformed under the extrusion of the outer plug-in nozzle 310 and fit tightly with the outer plug-in nozzle 310, thereby ensuring the sealing between the outer plug-in nozzle 310 and the air nozzle 340 of the compression band 300. It is understandable that the air nozzle 340 of the compression belt 300 and the external plug-in nozzle 310 may also be sealed by using a sealing gasket or a sealing ring, and the present application does not make any specific limitation on this.

[0176] Among them, the air nozzle 340 of the compression belt 300 partially extends into the avoidance groove 3191. The inner diameter of the avoidance groove 3191 is equal to or greater than the outer diameter of the air nozzle 340 of the compression belt 300, so that the air nozzle 340 of the compression belt 300 can be inserted into the avoidance groove 3191 to avoid the air nozzle 340 of the compression belt 300, so as to reduce the influence of the assembly structure between the air nozzle 340 of the compression belt 300 and the external plug-in nozzle 310 on the thickness of the wearable device 1000, which helps to achieve a light and thin design of the wearable device 1000. It should be understood that the air nozzle 340 of the compression belt 300 can also be completely accommodated in the avoidance groove 3191, in which case the external plug-in nozzle 310 does not extend and protrude from the bottom wall of the assembly groove 319, which can further reduce the influence of the assembly structure between the air nozzle 340 of the compression belt 300 and the external plug-in nozzle 310 on the thickness of the wearable device 1000.

[0177] The fixing part 33 is fixed to the side of the compression band 300 away from the main body part 31 and supports the compression band 300, which can not only prevent the air nozzle 340 of the compression band 300 from falling off from the external plug-in nozzle 310 and maintain the plug-in stability between the air nozzle 340 of the compression band 300 and the external plug-in nozzle 310, but also prevent the compression band 300 from falling off from the assembly groove 319, thereby improving the assembly stability between the compression band 300 and the bottom cover 30.

[0178] In the wearable device 1000 shown in this embodiment, the blood pressure measurement component 40 is integrated into the dial 100, and a compression belt 300 stacked with the strap 200 is added. When the wearable device 1000 is worn on the user's wrist, the user can measure the blood pressure anytime and anywhere and understand the user's own blood pressure condition in time without the need to use a sphygmomanometer for blood pressure measurement, which improves the convenience of blood pressure measurement for the user and enhances the user experience.

[0179] When the wearable device 1000 is worn on the wrist of the user, the compression band 300 fits the wrist of the user. When the wearable device 1000 receives the input of the blood pressure measurement instruction, the processor sends the blood pressure measurement signal to the air pump 41 and the pressure sensor 42. The air pump 41 inhales the gas from the external environment through the vent 109, and inflates and pressurizes the airbag 330 of the compression band 300 through the first fluid channel 306 and the first air nozzle 340 of the compression band 300. At this time, the compression band 300 will swell and compress the wrist artery of the user. The pressure sensor 42 detects the air pressure value in the airbag 330 of the compression band 300 through the second fluid channel 306 and the second air nozzle 340 of the compression band 300 and feeds it back to the processor in real time. The processor determines whether the air pressure value of the airbag 330 of the compression band 300 meets the requirements of blood pressure measurement. If not, the blood pressure measurement signal continues to be sent to the air pump 41, and the air pump 41 continues to inflate and pressurize the airbag 330 of the compression belt 300 until the processor determines that the air pressure value fed back by the pressure sensor 42 meets the blood pressure measurement requirements. The processor calculates the user's blood pressure based on the air pressure value fed back by the pressure sensor 42 in real time, and feeds it back to the user through the display screen. After the blood pressure measurement is completed, the processor stops sending the blood pressure measurement signal, and the air pump 41 and the pressure sensor 42 both stop working. The gas in the airbag 330 of the compression belt 300 is transmitted to the air pump 41 through the first air nozzle 340 and the first fluid channel 306 of the compression belt 300, and the air pump 41 discharges the gas through the vent 109. At this time, the compression belt 300 is restored to be flat and fits the user's wrist.

[0180] See also Fig. 22 and Fig.23 . Fig. 22 3 is a schematic diagram of the cross-sectional structure of the bottom cover 30 along the CC direction in the second wearable device 1000 provided in an embodiment of the present application. Fig.23 yes Fig. 22 A schematic diagram of the partial structure of the front view of the structure shown.

[0181] The wearable device 1000 shown in this embodiment is different from the wearable device 1000 shown in the above embodiment in that the external plug-in interface 305 and the internal plug-in interface 307 are respectively located on opposite sides of the top surface 301 of the bottom cover 30. Specifically, the external plug-in interface 305 is located below the top surface 301 of the bottom cover 30, and the external plug-in interface 305 and the top surface 301 of the bottom cover 30 form a first distance range [Z 11 , Z 12 ]. Among them, Z 11 <Z 12 The internal interface 307 is located above the top surface 301 of the bottom cover 30, and the internal interface 307 and the top surface 301 of the bottom cover form a second distance range [Z 21 , Z 22 ]. Where 0<Z 21 <Z 22 .

[0182] At this time, the first distance range [Z 11 , Z 12 ] and the second distance range [Z 21 , Z 22 That is, along the direction from the central axis O1 of the external plug-in interface 305 to the central axis O2 of the internal plug-in interface 307, the external plug-in interface 305 and the internal plug-in interface 307 are completely staggered, that is, the external plug-in interface 305 and the internal plug-in interface 307 do not share the thickness distance of the bottom cover 30 in the Z direction.

[0183] The fluid channel 306 is in a "U" shape and is parallel to the XY plane. A third distance range [Z 31 , Z 32 Specifically, the lower end surface of the fluid channel 306 is flush with the upper end surface of the external plug-in interface 305, that is, Z 31 =Z 12 The upper end surface of the fluid channel 306 is flush with the lower end of the insert interface 307, that is, Z 31 =Z 22 At this time, the third distance range [Z 31 , Z 32 ]Only the endpoint is within the second distance range [Z 21 , Z 22 ] and the first distance range [Z 11 , Z 12] in the collection. That is, along the direction of the central axis O1 of the external plug-in interface 305 toward the central axis O2 of the internal plug-in interface 307, the fluid channel 306 is staggered with both the external plug-in interface 305 and the internal plug-in interface 306. It can be understood that in the wearable device 1000 shown in this embodiment, the structures of the external plug-in interface 305, the fluid channel 306 and the internal plug-in interface 306 are simple, which simplifies the molding process of the back cover 30, thereby saving the preparation cost of the back cover 30.

Specifically, the bottom wall of the assembly groove 319 is partially recessed to form the second mounting groove 3121. That is, the opening of the second mounting groove 3121 is located at the bottom wall of the assembly groove 319. The second mounting groove 3121 is recessed from the bottom wall of the assembly groove 319 toward the top surface 315 of the boss 314, and passes through the bottom wall of the fluid groove 317.

[0187] In this embodiment, the back cover 30 also includes a second covering member 34, which is located on the side of the main body 31 away from the first covering member 32, and the second covering member 34 forms an external plug interface 305. Specifically, the second covering member 34 includes a second covering portion 341 and a second plug-in portion 342 connected to the second covering portion 341. The first covering portion 321 is generally a planar plate-shaped structure. The second covering portion 341 includes a top surface and a bottom surface that are arranged opposite to each other. The second plug-in portion 342 is connected to the top surface of the second covering portion 341. The second plug-in portion 342 extends from the top surface of the second covering portion 341 in a direction away from the bottom surface, and is generally a circular tubular structure. The second plug-in portion 342 includes a top surface that faces the same direction as the top surface of the second covering portion 341. The top surface of the second plug-in portion 342 is partially recessed to form the external plug interface 305, that is, the opening of the external plug interface 305 is located on the top surface of the second plug-in portion 342. The external plug interface 305 extends from the top surface of the second plug-in portion 342 toward the bottom surface of the second cover portion 341 and penetrates the bottom surface of the second cover portion 341. The second cover member 34 is made of elastic materials such as silicone or TPU.

[0188] The second fixing member is fixed to the side of the main body 31 away from the first covering member 32. Specifically, the second covering member 34 is fixed to the assembly groove 319 and is located between the main body 31 and the fixing member 33.

The second covering portion 341 of the second covering member 34 is fixed to the assembly groove 319, and the second plug portion 342 extends into the second installation groove 3121, so that the external plug interface 305 is connected to the fluid channel 306.

[0190] The air nozzle 340 of the compression belt 300 is plugged into the external plug-in interface 305 to achieve mutual communication with the external plug-in interface 305. The outer diameter of the air nozzle 340 of the compression belt 300 is slightly larger than the inner diameter of the external plug-in interface 305 to ensure a close fit between the air nozzle 340 of the compression belt 300 and the second cover 34, and to ensure the reliability of the connection between the air nozzle 340 of the compression belt 300 and the second cover 34.

[0191] In one embodiment, the elastic modulus of the air nozzle 340 of the compression belt 300 is greater than the elastic modulus of the second cover 34. That is, the air nozzle 340 of the compression belt 300 is made of a hard material, and the second cover 34 is made of an elastic material, that is, the air nozzle 340 of the compression belt 300 is made of a relatively hard material, and the second cover 34 is made of a relatively soft material. When the air nozzle 340 of the compression belt 300 is inserted into the external plug-in interface 305, the second cover 34 will be deformed under the extrusion of the air nozzle 340 of the compression belt 300 and fit closely with the air nozzle 340 of the compression belt 300, thereby ensuring the sealing between the air nozzle 340 of the compression belt 300 and the second cover 34.

Compared with the air nozzle 340 of the compression band 300 being sleeved on the external plug-in nozzle 310, the problem of being unable to achieve plug-in with the external plug-in nozzle 310 due to the processing error of the air nozzle 340 of the compression band 300 is avoided, that is, the requirements for the processing accuracy of the air nozzle 340 of the compression band 300 are reduced, which is beneficial to reducing the preparation cost of the compression band 300 and improving the product competitiveness of the wearable device 1000.

[0196] The air nozzle 340 of the compression belt 300 is sleeved on the external plug-in nozzle 310, that is, the external plug-in nozzle 310 is plugged into the air nozzle of the compression belt 300. The air nozzle 340 of the compression belt 300 protrudes from the circumference 320c of the cuff 320. The air nozzle 340 of the compression belt 300 extends from the circumference 320c of the cuff 320 along the XY plane.

[0197] In the wearable device 1000 shown in this embodiment, the compression band 300 is connected to the circumferential surface 313 of the main body 31. At this time, the compression band 300 does not occupy the bottom surface space of the bottom cover 30 at all, and partially or completely shares the thickness distance of the back cover 30 in the Z direction, so as to reduce the influence of the compression band 300 on the thickness of the wearable device 1000, which is conducive to the lightweight design of the wearable device 1000.

[0198] See also Fig.31 and Fig.32 . Fig.31 Schematic diagram of the exploded structure of the fifth wearable device 1000 provided in an embodiment of the present application. Fig.32 yes Fig.31 A schematic diagram of the exploded structure of the dial 100 in the wearable device 1000 is shown.

[0199] The wearable device 100 shown in this embodiment is different from the above four wearable devices 1000 in that the blood pressure measuring device 40 is a device that integrates the functions of an air pump and a pressure sensor, that is, the air pump and the pressure sensor are integrated into the blood pressure measuring device 40 to simplify the structure of the blood pressure measuring component 40, reduce the volume occupied by the blood pressure measuring component 40 in the inner cavity of the dial, and facilitate the thin and light design of the dial 200. Among them, the external plug-in interface, the fluid channel and the internal plug-in interface are all one. The air nozzle of the blood pressure measuring device 40 is connected to the internal plug-in interface, and the air nozzle 340 of the compression belt 300 is connected to the internal plug-in interface. At this time, the air nozzle 340 of the compression belt 300 is also one.

[0200] It should be understood that in the wearable device 1000 shown in this embodiment, components such as the frame 10 and the top cover 20 of the dial 100 and other structures of the strap 200 and the compression belt 300 are basically the same as the structures in the wearable device 1000 shown in the above four embodiments, and will not be repeated here.

[0202] The wearable device 100 shown in this embodiment is different from the above five wearable devices 100 in that the sensor assembly further includes a gas sensor 50, and the gas sensor 50 is located in the fluid channel 306. Specifically, the gas sensor 50 is fixed to the inner wall of the fluid channel 306 and is electrically connected to the processor, so as to analyze the gas components such as formaldehyde, oxygen or carbon dioxide in the surrounding environment of the wearable device 1000 when the wearable device 1000 measures blood pressure, thereby improving the functional diversity of the wearable device 1000 and enhancing the user experience.

[0203] Specifically, when the wearable device 1000 performs blood pressure measurement, the air pump 41 inhales gas from the surrounding environment, and fills the gas into the airbag 330 of the compression belt 300 through the fluid channel 306 and the air nozzle 340 of the compression belt 300 to measure blood pressure. Since the gas sensor 50 is located in the fluid channel 306, the gas will flow through the gas sensor 50. When the pressure sensor measures the air pressure value P in the airbag 33 of the compression belt 300 at a certain moment, the gas sensor 50 simultaneously analyzes the concentration value C of the gas to be measured, and the processor receives the air pressure value P fed back by the pressure sensor and the gas concentration value C fed back by the gas sensor 50, and processes the air pressure value P and the concentration value C to obtain the concentration of the gas measured in the environment.
