The blood pressure measurement assembly 40 is electrically connected to the processor. In this embodiment, the blood pressure measurement assembly 40 includes an air pump 41 and a pressure sensor 42 . The air pump 41 is electrically connected to the processor for receiving a control signal sent by the processor, and extracting gas or discharging gas according to the control signal. The pressure sensor 42 is arranged spaced apart from the air pump 41 and is electrically connected to the processor for receiving a control signal sent by the processor, and sensing the pressure signal according to the control signal, so as to convert the pressure signal into an electrical signal. Wherein, the pressure sensor may be a capacitive pressure sensor. Capacitive pressure sensors include at least two parallel plates of conductive material. When a force is applied to the pressure sensor, the capacitance between the electrodes changes. The processor determines the intensity of the pressure based on the change in electrode capacitance.

Specifically, the blood pressure measurement assembly 40 is located in the inner cavity 110 of the dial, and the air nozzle 401 of the blood pressure measurement assembly 40 and the insertion interface 307 communicate with each other. Wherein, the air nozzle 401 of the air pump 41 and the first insertion interface 307 communicate with each other, so that the air pump 41 transmits the pumped gas from the vent hole 109 to the first fluid channel 306 , or receives the air transmitted from the first fluid channel 306 . gas, and the gas is discharged through the vent hole 109 . The air nozzle 401 of the pressure sensor 42 is communicated with the second insertion interface 307, so that the pressure sensor 42 senses changes in air pressure through the second fluid channel 306 to measure blood pressure.

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 assembly 40 and the insertion interface 307 will be described. The air nozzles 401 of the blood pressure measuring assembly 40 mentioned below all refer to the air nozzles 401 of the air pump 41 , and the insertion interfaces 307 all refer to the first insertion interfaces 307 that communicate with the air nozzles 401 of the air pump 41 .

Repeat the description.

In this embodiment, the air nozzle 401 of the blood pressure measuring assembly 40 is inserted into the insertion interface 307 and extends along the Z direction. The gas nozzle 401 of the blood pressure measuring assembly 40 is inserted into the insertion interface 307 from the upper end of the insertion interface 307 . Along the Z direction, since the inner diameter of the upper end of the insertion interface 307 gradually increases, the gas nozzle 401 of the blood pressure measuring assembly 40 can be inserted into the insertion interface 307 more easily. In addition, the inner diameter of the lower end of the insertion interface 307 is equal to or slightly smaller than the outer diameter of the air nozzle 401 of the blood pressure measuring assembly 40 to ensure that when the air nozzle 401 of the blood pressure measuring assembly 40 extends from the upper end of the insertion interface 307 into the lower end , the air nozzle 401 of the blood pressure measurement assembly 40 is closely attached to the first cover member 32 to ensure the reliability of the connection between the air nozzle 401 of the blood pressure measurement assembly 40 and the first cover member 32 .

It should be understood that, in other embodiments, the formation manner of the interposer interface 307 may also be the same as that of the extra interposer interface 305 . At this time, the top surface 323 of the first covering portion 321 partially protrudes to form an inner plug-in mouth, and the inner side of the inner plug-in mouth forms an inner plug interface 307 . The air nozzle 401 of the blood pressure measuring assembly 40 and the inner plug connector are plugged with each other, that is, the air nozzle 401 of the blood pressure measurement assembly 40 is plugged into the plug interface 307, or the air nozzle 401 of the blood pressure measurement assembly 40 is sleeved on the inner plug connector mouth.

In one embodiment, the elastic modulus of the air nozzle 401 of the blood pressure measuring assembly 40 is greater than the elastic modulus of the first cover member 32 . That is, the air nozzle 401 of the blood pressure measuring assembly 40 is made of a hard material, and the first cover member 32 is made of an elastic material, that is, the air nozzle 401 of the blood pressure measuring assembly 40 is made of a relatively hard material, The first cover member 32 is made of a relatively soft material. When the gas nozzle 401 of the blood pressure measurement assembly 40 is inserted into the insertion interface 307 , the first cover member 32 will be squeezed by the gas nozzle 401 of the blood pressure measurement assembly 40 . It is pressed and deformed to closely fit with the air nozzle 401 of the blood pressure measuring assembly 40 , which ensures the tightness between the air nozzle 401 of the blood pressure measuring assembly 40 and the first cover member 32 . It should be understood that, the air nozzle 401 of the blood pressure measuring assembly 40 and the first cover member 32 can also be sealed by structures such as a sealing ring or a sealing gasket, which is not specifically limited in this application.

The sensor assembly is spaced apart from the blood pressure measuring assembly 40 and is electrically connected to the processor. Specifically, the sensor assembly includes a heart rate detection sensor, and the heart rate detection sensor faces the installation hole (not shown) or is at least partially accommodated in the installation hole. 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 with the wrist of the user, and the optical heart rate sensor can send a heart rate sensing signal through the mounting hole, so as to realize accurate detection of heart rate and improve the functional diversity of the wearable device 1000 , to improve the user experience. Of course, the heart rate detection sensor may also be a sensor that can perform heart rate detection, such as a bone conduction sensor.

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, so as to further improve the functional diversity of the wearable device 1000 and improve the user experience. user experience.

Please refer to FIG. 2 and FIG. 19 . FIG. 19 is a schematic structural diagram of the compression strap 300 in the wearable device 1000 shown in FIG. 2 .

The compression band 300 is located on one side of the dial 100 . The compression band 300 includes a cuff 320, an air bag (not shown) accommodated in the cuff 320, and a gas nozzle 340 communicated with the air bag. The cuff 320 includes a top surface 320a and a bottom surface 320b disposed opposite to each other and a peripheral surface 320c connected between the top surface 320a and the bottom surface 320b. The bladder is located at the position of the cuff 320 near the dial 100 . The air nozzle 340 protrudes from the top surface 320 a 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. Wherein, the gas nozzle 340 and the airbag can be made of the same material, and in this case, the gas nozzle 340 can be integrally formed with the airbag. Alternatively, the material of the gas nozzle 340 and the airbag may also be different. In this case, the gas nozzle 340 may be assembled and formed with the airbag in a detachable manner.

In this embodiment, there are two air nozzles 340 . The two air nozzles 340 are the first air nozzle 340 and the second air nozzle 340 respectively, and the first air nozzle 340 and the second air nozzle 340 are arranged at intervals along the X direction. The structures of the first air nozzle 340 and the second air nozzle 340 are basically the same.

See Figure 20 and Figure 21a. FIG. 19 is a schematic diagram of the assembly structure of the compression strap 300 and the dial 100 in the wearable device 1000 shown in FIG. 2 . FIG. 21a is a schematic structural diagram of the structure shown in FIG. 20 cut along the G-G direction. 20 and 21a only show the part where the compression band 300 is connected to the dial 100 .

The compression band 300 partially extends into the mounting groove 319 and is fixed in the mounting groove 319 , and partially extends out of the mounting groove 319 . At this time, the compression band 300 completely shares the thickness distance of the bottom cover 30 in the Z direction, which reduces the influence on the thickness of the wearable device 1000 when the compression band 300 is assembled on the bottom cover 30 , and helps to realize the wearable device 1000 thin and light design.

The air nozzle 340 of the compression belt 300 is located in the fitting groove 319 . Specifically, the air nozzle 340 of the compression belt 300 and the external insertion interface 305 communicate with each other. That is, the air nozzle 340 of the compression belt 300 communicates with the air nozzle 401 of the blood pressure measuring assembly 40 through the fluid channel 306 . At this time, the air bag 330 of the compression belt 300 communicates with the external insertion port 305 through the air nozzle 340 . That is, the air bag 330 of the compression belt 300 communicates with the air nozzle 401 of the blood pressure measurement assembly 40 through the air nozzle 340 and the fluid passage 305 of the compression belt 300 .

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, the flow resistance of the gas in the fluid channel 306 is small, and the air pressure between the gas nozzle 340 of the belt 300 and the blood pressure measuring assembly 40 is ensured. The gas exchange rate between the mouths 401 is large enough to facilitate the rapid flow of gas between the gas nozzle 340 of the compression belt 300 and the gas nozzle 401 of the blood pressure measuring assembly 40 , and is conducive to improving the blood pressure detection efficiency of the wearable device 1000 .

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 measuring assembly 40 , so that the compression band 300 will not be easily affected during the process of assembling or disassembling the compression band 300 . The blood pressure measurement assembly 40 is displaced, which avoids the problem of damage to the blood pressure measurement assembly 40 when the compression belt 300 moves, and is beneficial to improve the service life of the wearable device 1000 .

Moreover, the external insertion interface 305 , the fluid channel 306 and the internal insertion interface 307 are all integrated in the bottom cover 30 of the dial 100 , and it is not necessary to set the air nozzle 340 connected to the compression belt 300 and the blood pressure measuring assembly 40 in the dial cavity 110 . The communication pipeline between the mouths 340 avoids the space occupancy rate of the communication pipeline in the inner cavity 110 of the dial, is beneficial to improve the space utilization rate of the inner cavity 110 of the dial, realizes the light and thin design of the dial 100, and improves the performance of the wearable device 1000. Exquisite appearance.

Furthermore, the outer plug-in interface 305 communicated with the air nozzle 340 of the compression band 300 is closer to the frame 10, that is, the inner plug-in interface 307 communicated with the air nozzle 401 of the blood pressure measuring assembly 40 is closer to the middle of the bottom cover 30, so that the The air nozzle 340 can communicate with the air nozzle 401 of the blood pressure measurement assembly 40 without extending directly below the blood pressure measurement assembly 40, which can not only reduce the extension length of the compression band 300 under the dial 100, but also help reduce the wearable device. The overall thickness of the wearable device 1000 realizes the thin and light design of the wearable device 1000, and also makes the position design between the compression band 300 and the blood pressure measurement component 40 more flexible, thereby making the battery and/or sensor module located in the inner cavity 110 of the dial more flexible. The location design of the functional device is also more flexible, which is beneficial to improve the space utilization rate of the inner cavity 110 of the dial, and helps to realize the thin and light design of the wearable device 1000 .

Please refer to FIG. 21a and FIG. 21b. FIG. 21b is an enlarged schematic view of the H region in the structure shown in FIG. 21a.

In this embodiment, the first air nozzle 340 of the compression belt 300 and the first external insertion interface 305 communicate with each other. At this time, the first air nozzle 340 of the compression belt 300 communicates with 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 outside air drawn through the vent hole 109 into the air bag 330 of the compression belt 300 through the first fluid channel 306 and the air nozzle 340 of the compression belt 300, so as to realize the measurement of blood pressure. Inflation of the bladder 330 of the compression band 300. After 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 and the first fluid channel 306 of the compression belt 300 , and the air pump 41 can discharge the air through the ventilation hole 109 . Among them, when the air pump 41 inflates the airbag 330, the flow path of the gas is shown by the dotted arrow in Fig. 21b, and when the air in the airbag 330 is discharged by the air pump 41, the flow path of the gas is shown by the solid line arrow in Fig. 21b, and then The descriptions of the solid line arrows and the dashed line arrows in the accompanying drawings should be understood in the same way.

The second air nozzle 340 of the compression belt 300 and the second external insertion interface 305 communicate with each other. At this time, the second air nozzle 340 of the compression belt 300 communicates with 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 air bag 330 of the compression band 300 through the second fluid channel 306 .

In the wearable device 1000 shown in this embodiment, the air pump 41 and the air nozzle 401 of the pressure sensor 42 communicate with the air nozzle 340 of the compression belt 300 through two fluid channels 306 respectively, instead of sharing one fluid channel, which can not only improve blood pressure measurement The installation flexibility of the assembly 40 in the inner cavity 110 of the dial can also avoid mutual interference of gas transmission between the air pump 41 and the pressure sensor 42 and the air bag 330 of the compression band 300, which is beneficial to improve the blood pressure measurement assembly 40 during the blood pressure measurement process. measurement sensitivity and accuracy.

Next, the assembly structure between the first air nozzle 340 of the compression belt 30 and the first outer plug-in nozzle 310 will be described as an example. The mouth 340 and the external plug-in nozzle 310 refer to the first external plug-in nozzle 310 . It should be understood that the assembly structure between the second air nozzle 340 and the second external plug-in nozzle 310 of the compression belt 300 is basically the same as the assembly structure between the first air nozzle 340 and the first plug-in nozzle 310 , which will be described later. The description will not be repeated.

Specifically, the air nozzle 340 of the compression belt 300 is sleeved on the outer plug-in nozzle 310 , that is, the outer plug-in nozzle 310 is inserted 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. The inner diameter of the air nozzle 340 of the compression belt 300 is slightly smaller than the outer diameter of the outer plug-in nozzle 310, so that when the air nozzle 340 of the compression belt 300 is sleeved on the outer plug-in nozzle 310, the outer plug-in nozzle 310 is plugged into the outer plug-in nozzle 310. When the air nozzle 340 of the compression belt 300 is compressed, the air nozzle 340 of the compression belt 300 can be closely attached to the outer plug-in nozzle 310 , ensuring the reliability of the connection between the air nozzle 340 of the compression belt 300 and the outer plug-in connection nozzle 310 .

It can be understood that, compared with the embodiment in which the second distance range [Z ₂₁ , Z ₂₂ ] completely coincides with the first distance range [Z ₁₁ , Z ₁₂ ], in the wearable device 1000 shown in this embodiment, due to the fact that along the In the Z direction, the length dimension of the external plug-in nozzle 310 is larger, 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, Not only the reliability of connection between the air nozzle 340 of the compression band 300 and the external plug-in nozzle 310 is increased, but also the risk of air leakage between the air nozzle 340 of the compression band 300 and the external plug-in nozzle 310 is reduced.

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 belt 300 . That is, the main body 31 is made of hard material, and the air nozzle 340 of the compression belt 300 is made of elastic material. That is, the external plug-in mouth 310 of the main body 31 is made of a relatively hard material, and the air nozzle 340 of the compression belt 300 is made of a relatively soft material. When the external plug nozzle 310 is inserted into the air nozzle 340 of the compression belt 300 , since the external plug nozzle 310 is relatively hard and the air nozzle 340 of the compression belt 300 is relatively soft, the air nozzle 340 of the compression belt 300 will be in the outer plug of the nozzle 310 . It is deformed under pressing and closely fits with the external plug-in nozzle 310 , which ensures the sealing between the external plug-in nozzle 310 and the air nozzle 340 of the compression belt 300 . It can be understood that, sealing between the air nozzle 340 of the compression belt 300 and the external plug-in nozzle 310 can also be achieved by using a sealing gasket or a sealing ring, which is not specifically limited in this application.

The air nozzle 340 of the compression belt 300 partially extends into the escape groove 3191 . The inner diameter of the avoidance groove 3191 is equal to or larger 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 pressure of the compression belt 300. The assembling structure between the air nozzle 340 and the external plug connector 310 has an influence on the thickness of the wearable device 1000 , which is helpful to realize the thin and light design of the wearable device 1000 . It should be understood that the air nozzle 340 of the compression band 300 can also be completely accommodated in the escape groove 3191 . At this time, the outer plug nozzle 310 does not need to extend and protrude from the bottom wall of the groove 319 , which can further reduce the compression band 300 The assembly structure between the air nozzle 340 and the external plug connector 310 affects the thickness of the wearable device 1000 .
