[0091] An embodiment of the present application provides a wearable device 100, which can be a smart wearable device worn on the wrist. Specifically, the smart wearable device for wearing on the wrist can be a smart watch, a sports watch, a smart bracelet, or other wearable devices; this embodiment is not limited to this, and this embodiment is described using a smart watch as an example.

[0092] Among them, the wearable device 100 can obtain the wearer's vital sign data through the integrated sensor. In the embodiment of the present application, the wearable device 100 has the function of measuring blood pressure.

[0093] Among them, in the related art, in wearable devices with blood pressure measurement, the wearable devices often include a device body, a strap and an airbag, wherein an air port is opened on the bottom shell of the device body, the airbag is fixed on the bottom shell of the device body and connected to the air port, and the two ends of the airbag are detachably connected to the strap. However, since the air port is opened on the bottom shell of the device body, the bottom shell is easy to hide dust. In addition, since the airbag is arranged on the bottom shell of the device body, the airbag occupies the space of the bottom shell, which limits the internal space of the bottom shell. In addition, the airbag and the strap are separately arranged. During the measurement process, the connection between the strap and the airbag does not fit the wrist, causing discomfort when wearing and affecting the measurement accuracy.

[0094] In order to solve at least one of the above problems, an embodiment of the present application provides a wearable device, which includes a device body, at least one group of strap components and a pressure measuring component, wherein an air port is opened on the side wall of the device body, and one of the at least one group of strap components includes a first strap body and an air bag, the air bag is detachably attached to the inner side of the first strap body, one end of the air bag has a first air nozzle, the first air nozzle is connected to one end of the air flow channel in the end of the first strap body close to the device body, and the other end of the air flow channel is connected to the air port when the first strap body is connected to the side wall of the device body, and the end of the first strap body connected to the device body covers the air port. In this way, when the wearable device is worn on the wrist, since the air bag is attached to the first strap body The first air nozzle of the airbag is connected to the airflow channel at one end of the first watchband body on the inner side of the body. The airbag and the first watchband body are assembled into an integral structure and connected to the device body. In this way, after inflation, the airbag can achieve a good fit with the wrist, so that the airbag and the wrist do not cause discomfort when the wearable device is worn or when blood pressure is measured, thereby improving the wearing comfort of the wearable device during wear and blood pressure measurement. When one end of the first watchband body provided with the airflow channel is connected to the device body, the end of the first watchband body connected to the side wall of the device body does not cover the air port on the side wall of the device body, thereby preventing the air port of the device body from being exposed, thereby preventing the problem of dust accumulation at the air port of the wearable device. In addition, the airbag is located on the inner side of the first watchband body and does not occupy space in the bottom shell of the device body, making the wearable device body thinner when it has a blood pressure measurement function. Therefore, the wearable device provided by the embodiment of the present application solves the problems of discomfort during wear and dust accumulation at the air port of the wearable device during blood pressure measurement.

[0095] The specific structure of the wearable device provided in the embodiments of the present application is described in detail below.

[0096] As shown in FIG1 , the wearable device 100 provided in an embodiment of the present application may include: a device body 110 and at least one set of strap assemblies 120. For example, in FIG1 , the number of strap assemblies 120 is two sets, and the two sets of strap assemblies 120 are respectively a first strap assembly 120a and a second strap assembly 120b. Of course, in some examples, for example, the number of strap assemblies 120 can also be one set (see FIG24 below). At least one end of each set of strap assemblies 120 is connected to the side wall 111 of the device body 110. For example, in FIG1 , one end of each set of strap assemblies 120 is connected to the side wall 111 of the device body 110. In some examples, both ends of the strap assemblies 120 are connected to the side wall 111 of the device body 110 (see FIG24 below).

[0097] As shown in FIG2 , the device body 110 has a side wall 111 on which an air vent 1111 is provided. The side wall 111 of the device body 110 may be a ring-shaped middle frame structure. When there are two groups of strap assemblies 120, the two groups of strap assemblies 120 may be respectively connected to the two opposite side walls 111 of the device body 110.

[0098] As shown in FIG3 , one of the at least one set of strap assemblies 120 may include a first strap body 121 and an airbag 123. For example, the strap assemblies 120 may be two sets, namely a first strap assembly 120a and a second strap assembly 120b. As shown in FIG3 , the first strap assembly 120a may include the first strap body 121 and the airbag 123. As shown in FIG3 , the airbag 123 is detachably attached to the inner side of the first strap body 121 (i.e., the side of the first strap body 121 facing the wrist), and one end of the first strap body 121 is connected to the device body 110. Alternatively, the second strap assembly 120b may include the airbag 123, and one of the two sets of strap assemblies 120 may include the airbag 123. In this embodiment of the present application, the first strap assembly 120a having an inflatable airbag 123 is used as an example for description. Of course, in some examples, both the first strap assembly 120a and the second strap assembly 120b may be provided with airbags 123. It should be noted that the airbags 123 in the strap assembly 120 may be inflated when inflated, thereby enabling the user's blood pressure to be measured.

[0099] 4A , one end of the airbag 123 is provided with a first air nozzle 1231, and one end of the first strap body 121 is provided with an air flow channel 1411. The first air nozzle 1231 is connected to one end of the air flow channel 1411. For example, the first air nozzle 1231 can be detachably connected to one end of the air flow channel 1411. In this way, the airbag 123 is connected and connected to the air flow channel 1411 of the first strap body 121, so that the airbag 123 and the first strap body 121 form a first strap component 120a (see FIG3 ) of an integral structure, and the inner side of the first strap component 120a is the airbag 123. When worn, the airbag 123 faces the wrist. When blood pressure is measured, the airbag 123 inflates, which can achieve a good fit with the wrist, so that the airbag 123 will not be uncomfortable to wear and the wrist will not be uncomfortable when the wearable device is worn or when blood pressure is measured, thereby avoiding the problem of discomfort when wearing the wearable device.

[0100] As shown in FIG4A , the other end of the airflow channel 1411 is connected to the air port 1111 when the first strap body 121 is connected to the side wall of the device body 110. This allows the airbag 123 to be connected to the air port 1111. In this manner, in order to achieve the blood pressure measurement function, the embodiment of the present application further includes a pressure measuring assembly 130, as shown in FIG4A . The pressure measuring assembly 130 is disposed within the device body 110 and is connected to the air port 1111. The pressure measuring assembly 130 inflates the airbag 123 through the air port 1111.

[0101] As shown in FIG4A , the pressure measurement assembly 130 includes a differential pressure sensor 131, an air circuit 132, and an air pump 134. The air port 1111 is connected to the differential pressure sensor 131 and the air pump 134 through the air circuit 132. A control valve 133 is provided on the air circuit 132. The control valve 133 can control the airflow in the air circuit 132. The air pump 134 can provide airflow, which flows into the airbag 123 of the airbag 123 through the air circuit 132. The differential pressure sensor 131 is used to obtain the pressure difference of the airflow. The differential pressure sensor 131 can be electrically connected to the circuit board in the device body 110. The circuit board obtains the user's blood pressure value based on the pressure difference signal obtained by the differential pressure sensor 131.

[0102] In the embodiment of the present application, to prevent dust from accumulating at the air vent 1111 of the device body 110, the air vent 1111 of the device body 110 is designed to be invisible. As shown in FIG4A , when one end of the first strap assembly 120a is connected to the side wall 111 of the device body 110, the end of the first strap assembly 120a connected to the device body 110 covers the air vent 1111. As shown in FIG4B , when the first strap assembly 120a is connected to the side wall 111 of the device body 110, the airbag 123 is connected to the air vent 1111, and the air vent 1111 is invisible from the outside of the device body 110, thereby preventing dust accumulation at the air vent. Furthermore, the airbag 123 is located on the strap assembly 120, eliminating space on the bottom shell of the device body 110. This allows the wearable device to be thinner when equipped with a blood pressure measurement function. Therefore, the wearable device provided in the embodiment of the present application solves the problems of uncomfortable wear during blood pressure measurement and dust accumulation at the air vent.

[0103] Therefore, the wearable device 100 provided in the embodiment of the present application has an air vent 1111 on the side wall 111 of the device body 110, and one of the at least one group of strap assemblies 120 has an inflatable airbag 123, and one end of the strap assembly 120 provided with the airbag 123 covers the air vent 1111, and the air vent 1111 and the airbag 123 are connected through the air flow channel 1411 at one end of the first strap body 121. In this way, the inflatable airbag 123 is located on the strap assembly 120. When the strap assembly 120 is connected to the device body 110, on the one hand, the airbag 123 is connected to the air vent 1111, thereby realizing the function of blood pressure measurement. On the other hand, one end of the strap assembly 120 covers the air vent 1111 on the device body 110, so that dust is not easily accumulated at the air vent 1111 of the device body 110. In addition, the inflatable airbag 123 is located on the inner side of the first strap body 121, so that when blood pressure is measured during wearing, the airbag 123 can fit well with the wrist, so that there will be no wearing discomfort between the airbag and the wrist during the wearing process and blood pressure measurement, thereby improving the wearing comfort of the wearable device during the wearing process and blood pressure measurement. Therefore, the wearable device provided in the embodiment of the present application solves the problems of uncomfortable wearing of the wearable device during blood pressure measurement and dust accumulation in the air outlet.

[0104] In the embodiment of the present application, to connect one end of the first strap assembly 120a to the sidewall 111 of the device body 110, as shown in FIG5A , one end of the first strap body 121 has a first connecting structure 141, which includes an airflow channel 1411 (see FIG4A or FIG6 below). One end of the first connecting structure 141 is connected to the first strap body 121, while the other end of the first connecting structure 141 is detachably connected to the sidewall 111 of the device body 110. As shown in FIG5A and FIG5B , the first air nozzle 1231 of the airbag 123 is connected to the first connecting structure 141, and the first air nozzle 1231 communicates with the air port 1111 via the airflow channel 1411. It should be noted that in the embodiment of the present application, when one end of the first connecting structure 141 is connected to the first strap body 121, the first connecting structure 141 can be integrally designed with the first strap body 121 through a molding process or assembly method.

[0105] In the embodiment of the present application, when the first strap body 121 is fitted with the airbag 123, the first strap body 121 and the airbag 123 are fitted together by a buckling manner. Therefore, a buckling strip 1233 is provided on one of the first strap body 121 and the airbag 123, and a groove 1214 that buckles with the buckling strip 1233 is provided on the other of the strap body and the airbag 123. For example, referring to FIG5C , the airbag 123 is provided with a buckling strip 1233, and the first strap body 121 is provided with a groove 1214 that buckles with the buckling strip 1233. Of course, in some examples, the structure of the buckling strip 1233 is not limited to the strip shape shown in FIG5C . For example, referring to FIG5D , the buckling strip 1233 provided on the airbag 123 can be mushroom-shaped, and the first strap body 121 is provided with a groove 1214 that buckles with the mushroom-shaped buckling strip 1233.

[0106] In the embodiment of the present application, the first strap body 121 and the airbag 123 are engaged with each other through the buckling strip 1233 and the slot 1214, thereby achieving a good fit between the strap assembly 120 and the airbag 123, improving wearing comfort, and saving space, thereby solving the problem of discomfort caused by the lack of fit between the strap and the airbag 123 during wearing.

[0107] In one possible implementation, referring to Figures 6 and 7, one end of the first connecting structure 141 connected to the device body 110 has a second air nozzle 1412 connected to the air flow channel 1411, and the air flow channel 1411 is sealed and connected to the air port 1111 through the second air nozzle 1412. For example, a sealing structure can be provided on the outer periphery of the second air nozzle 1412, so that after the second air nozzle 1412 is inserted into the air port 1111, the air port 1111 and the second air nozzle 1412 are sealed and connected.

[0108] In one possible implementation, in order to achieve a detachable connection between the first strap assembly 120a and the device body 110, as shown in Figure 8A, it also includes: a first control button 150, as shown in Figure 8B, the first control button 150 is provided on the device body 110, and the first control button 150 is used to control the connection or disconnection between the first connection structure 141 and the device body 110. For example, when the first connection structure 141 and the device body 110 are engaged and connected, the first control button 150 locks the connection between the first connection structure 141 and the device body 110, so that the first connection structure 141 and the device body 110 cannot be disconnected. When the first strap assembly 120a needs to be disconnected from the device body 110, the first control button 150 is pressed to unlock the connection between the first connection structure 141 and the device body 110. In this way, there is no connection between the first strap assembly 120a and the device body 110, and the first strap assembly 120a can be disconnected from the device body 110. This not only realizes the detachable connection between the strap assembly 120 and the device body 110, but also makes it compatible with more functional straps, making the wearable device 100 a multifunctional smart strap, not just limited to blood pressure measurement.

[0109] Among them, when the first control button 150 controls the first connecting structure 141 to be connected or disconnected from the device body, please refer to Figure 8A for details. The first control button 150 may include a button body 151 and an elastic member 152. The button body 151 has a pressing portion 1511 and two clamping portions 1512 respectively located on both sides of the pressing portion 1511. As shown in Figure 8B, the pressing portion 1511 of the first control button 150 is exposed on the outer surface of the device body 110. The pressing portion 1511 is used to move along the thickness direction of the device body (as shown in the arrow direction in Figure 8B) when pressed. For example, when the user applies a force in the direction of the arrow in Figure 8B to the pressing portion 1511, the first control button 150 moves in the direction indicated by the arrow, and the elastic member 152 is compressed. After the external force on the pressing portion 1511 is removed, the elastic force of the elastic member 152 causes the pressing portion 1511 to reset. The clamping portion 1512 and the elastic member 152 of the first control button 150 are located inside the device body 110 .

[0110] As shown in FIG8C , one end of the elastic member 152 is connected to the pressing portion 1511, and the other end of the elastic member 152 is connected to the device body 110. The elastic member 152 is used to retractably arrange the button body 151 on the device body 110. As shown in FIG8C and FIG8B , the pressing portion 1511 (see FIG8C ) of the button body 151 is located at the edge of the bottom shell 114 of the device body 110. As shown in FIG9 , the clamping portion 1512 is used to cooperate with the clamping groove 141a provided on the first connecting structure 141 to connect the first connecting structure to the device body 110. When it is necessary to disassemble the first strap assembly 120a from the device body 110, a force in the direction of the arrow shown in FIG9 is applied to the pressing portion 1511 to press the button. When the pressing portion 1511 moves in the direction of the arrow, it drives the engaging portion 1512 to move in the same direction. This disengages the engaging portion 1512 from the engaging slot 141a on the first connecting structure 141, disengaging the first control button 150 from the first connecting structure 141. The first strap assembly 120a can then be removed from the device body 110. After the external force on the pressing portion 1511 is removed, the elastic force of the elastic member 152 drives the button body 151 in a direction opposite to the arrow, thereby resetting the button body 151.

[0111] When the first connecting structure 141 of the first strap assembly 120a is connected to the device body 110 again, the pressing part 1511 can be pressed again to make the clamping part 1512 move upward a certain distance along the arrow. After one end of the first connecting structure 141 where the clamping slot 141a is set is inserted into the device body 110, the pressing part 1511 is applied with external force to make the clamping part 1512 snap into the clamping slot 141a. Alternatively, a guide surface (not shown) can be provided at one end of the first connecting structure 141 where the clamping slot 141a is set. When the first connecting structure 141 is inserted into the device body 110, the clamping part 1512 is driven to move along the direction of the arrow until the clamping part 1512 snaps into the clamping slot 141a, and then the assembly is in place, thereby realizing the connection between the first connecting structure 141 and the first control button 150.

[0112] In the embodiment of the present application, an airbag 123 is provided in the first strap assembly 120a, and an airbag 123 is not provided in the second strap assembly 120b. As shown in Figure 9, the second strap assembly 120b includes a second strap body 122 and a buckle 1221. One end of the second strap body 122 is connected to the device body 110, and the other end of the second strap body 122 is connected to the buckle 1221. The buckle 1221 is used to be detachably connected to one end of the first strap body 121.

[0113] When worn, the first strap body 121 and the second strap body 122 are detachably connected via the clasp 1221. As shown in FIG10 , the first strap body 121 is provided with a plurality of first clasps 1211 spaced apart from each other. As shown in FIG11 , the first clasps 1211 are configured to engage with the clasp 1221. Thus, after the first strap body 121 and the second strap body 122 are engaged, the second strap body 122 is positioned outside the first strap body 121 and does not interfere with the airbag 123.

[0114] In the embodiment of the present application, in order to ensure that the airbag 123 has more fitting positions with the wrist, as shown in Figure 10, the length of the first strap body 121 is greater than the length of the second strap body 122, and the airbag 123 extends along one end of the first strap body 121 to the other end of the first strap body 121. In this way, when the wearing device is worn on the wrist, since the length of the first strap body 121 is larger, and when the second strap body 122 is matched with the first strap body 121, the second strap body 122 is located on the outside of the first strap body 121. In this way, the length of the airbag 123 fitting with the wrist is longer, thereby achieving a larger area of ​​fitting between the airbag 123 and the wrist, ensuring accurate blood pressure detection.

[0115] In the embodiment of the present application, as shown in Figure 10, the end of the first strap body 121 facing away from the device body 110 is provided with a belt loop 1213 for the buckle 1221 to pass through. The belt loop 1213 is rotatably connected to the first strap body 121, so that the buckle 1221 of the second strap body 122 can pass through the belt loop 1213 and be fastened with the first buckle position 1211 of the first strap body 121.

[0116] In particular, in the embodiment of the present application, in order to make the fastening between the first strap body 121 and the second strap body 122 more stable, as shown in Figure 10, a buckle 1212 is provided on the outer side surface of the first strap body 121 (i.e., the side facing away from the airbag 123), and a plurality of second buckle positions 1222 are provided on the second strap body 122 at intervals, as shown in Figure 11, the buckle 1212 is used to be fastened and connected with the second buckle positions 1222. After the first strap body 121 and the second strap body 122 are fastened, as shown in Figure 12, the first strap body 121 is located on the inner side facing the wrist, and the second strap body 122 is located on the outer side.

[0117] In an embodiment of the present application, one structure of the clasp 1221 can be seen in FIG13 . The clasp 1221 can include a clasp cover 1221a, which is provided with a fixed post 1221c and a movable sliding buckle 1221b. The fixed post 1221c is used to cooperate with one of the first buckle positions 1211, and the sliding buckle 1221b is used to engage with the other first buckle position 1211. As shown in FIG14 , the clasp cover 1221a can include an upper shell 1221d and a lower shell 1221e, wherein the lower shell 1221e is provided with a fixed post 1221c, and a movable slider 1221f is provided between the upper shell 1221d and the lower shell 1221e. The slider 1221f has a sliding buckle 1221b at one end, and the slider 1221f is slidably arranged in the clasp cover 1221a via a spring 1221j.

[0118] When wearing the watch, as shown in FIG15A , one end of the slider 1221f is first pushed (moving in the -x direction), compressing the spring 1221j. The slider 1221f drives the sliding buckle 1221b to the left, allowing the sliding buckle 1221b to extend into the first buckle position 1211 of the first watchband. The slider 1221f is then released. Under the elastic force of the spring 1221j, the slider 1221f moves in the x direction, causing the sliding buckle 1221b to move rightward. The end of the sliding buckle 1221b is then caught on the edge of the first buckle position 1211. Thus, the sliding buckle 1221b limits the first watchband body 121 in both the x and z directions. The fixing post 1221c extends into the other first buckle position 1211, providing positioning in the x direction. In the embodiment of the present application, a dual positioning function in the x-direction is achieved by the fixed column 1221c and the movable sliding buckle 1221b, so that a stable locking effect is achieved between the buckle 1221 and the first strap body 121.

[0119] Therefore, by setting the fixed column 1221c and the movable sliding buckle 1221b in the above-mentioned buckle 1221, the opening and closing of the buckle 1221 is achieved in the smallest space. In addition, the convenience of opening and closing the two strap bodies and the aesthetics of the buckle 1221 are achieved.

[0120] In the embodiment of the present application, the first strap body 121 and the second strap body 122 may both be made of a flexible plastic material. For example, the first strap body 121 and the second strap body 122 may both be plastic straps.

[0121] When both the first and second strap bodies 121, 122 are plastic straps, the tensile deformation of the strap bodies significantly affects the airbag 123 during blood pressure measurement. Therefore, in the embodiment of the present application, a tensile interlayer 126 is provided on the inner sides of the first and second strap bodies 121, 122. For example, as shown in FIG15B , the tensile interlayer 126 is provided on the inner side of the first strap body 121. When the airbag 123 is attached to the inner side of the first strap assembly 120a, the tensile interlayer 126 is located between the first strap assembly 120a and the airbag 123. Alternatively, in some examples, the tensile interlayer 126 may be provided on the inner sides of the first and second strap bodies 121, 122. For example, as shown in FIG15C , the tensile interlayer 126 is provided on the inner side of the first strap body 121.

[0122] By providing a tensile-resistant interlayer 126 through the strap assembly 120, when the first strap body 121 and the second strap body 122 are plastic straps, when the first strap body 121 and the second strap body 122 are stretched during the blood pressure measurement process, it will not affect the airbag 123, thereby ensuring the accuracy of the blood pressure measurement.

[0123] It should be noted that the tensile interlayer 126 may be a layer made of a material with high tensile strength. For example, the material with high tensile strength may be polyimide (PI) or nylon.

[0124] When the tensile-resistant interlayer 126 is disposed within the first and second strap bodies 121, 122, it can be integrally formed with a high-tensile-strength material during the molding process of the first and second strap bodies 121, 122. For example, the first and second strap bodies 121, 122 can be made of a rubber compound, which is first molded in a single step. During this single step, a middle plate with positioning posts is placed between the two rubber compounds to position the film material. After the single step, the middle plate is removed from between the rubber compounds, and the entire assembly is subjected to a secondary molding process to integrate the high-tensile-strength material with the rubber compound. After molding, the tensile strength of the first and second strap bodies 121, 122 is greatly enhanced. When the first and second strap bodies 121, 122 are pulled, the tensile-resistant interlayer 126 within the first and second strap bodies 121, 122 withstands the tensile force, thereby controlling deformation of the first and second strap bodies 121, 122 to a relatively small range.

[0125] In the embodiment of the present application, in addition to the blood pressure detection function, the wearable device 100 may also be provided with other detection functions. For example, as shown in FIG16 , a detection electrode 124 is further provided on the clasp 1221, and a flexible circuit board 125 is provided in the second strap body 122. As shown in FIG17 , the detection electrode 124 is electrically connected to the circuit board (not shown) in the device body 110 via the flexible circuit board 125. The detection electrode 124 can be exposed on the clasp 1221. The detection electrode 124 can be a sensor that can be attached to the leg or chest of a human body to measure heart rate or body fat. In the embodiment of the present application, by providing the detection electrode 124 on the clasp 1221, the function of the wearable device 100 is increased, achieving the purpose of human contact sensor and improving the accuracy of electrocardiogram measurement.

[0126] Among them, in the embodiment of the present application, in order to realize the connection between the second strap body 122 and the side wall 111 of the device body 110, as shown in Figure 18, it also includes: a second connecting structure 142, one end of the second connecting structure 142 is connected to the second strap body 122, and the other end of the second connecting structure 142 is connected to the device body 110.

[0127] To achieve a snap-on, detachable connection between the second strap body 122 and the device body 110, the device further includes a second control button 160 (see FIG. 9 ). The second control button 160 is disposed on the device body 110 and is used to control the connection or disconnection of the second connection structure 142 from the device body 110. The structure and functional principles of the second control button 160 can be referenced to the first control button 150 in FIG. 8A . For example, the second control button 160 can include a button body 151 and an elastic member 152. The button body 151 has a pressing portion 1511 and two engaging portions 1512 located on either side of the pressing portion 1511. The second connection structure 142 includes an engaging slot 142a that engages with the engaging portions 1512 of the second control button 160. The coordination between the second control button 160 and the second connection structure 142 can be referenced to the coordination between the first control button 150 and the first connection structure 141, and will not be further described in this embodiment.

[0128] Among them, when the detection electrode 124 is set on the buckle 1221, in order to realize the signal transmission between the detection electrode 124 and the device body 110, therefore, refer to Figure 18, and a conductive contact 1421 is provided on the second connecting structure 142, and the conductive contact 1421 is electrically connected to the flexible circuit board 125. A conductive terminal 113 (see Figure 17) that is electrically in contact with the conductive contact 1421 is provided on the side of the device body 110 connected to the second connecting structure 142, and the conductive terminal 113 is electrically connected to the circuit board in the device body 110. In this way, when the second strap body 122 is connected to the device body 110 through the second connecting structure 142, the conductive terminal 113 and the conductive contact 1421 are connected, and the detection electrode 124 is connected to the circuit board in the device body 110 through the flexible circuit board 125, thereby realizing signal transmission.

[0129] It should be noted that in the embodiment of the present application, in Figure 17, the detection electrode 124 is provided on the buckle 1221. In some examples, other detection electrodes 124 can also be provided on the side wall 111 and the bottom wall 112 of the device body 110, so as to increase the functionality of the wearable device 100.

[0130] When the detection electrode 124 is set on the buckle 1221, as shown in Figure 19, a mounting groove can be set on one side of the buckle 1221, and the detection electrode 124 can be set in the mounting groove.

[0131] In an embodiment of the present application, another structure of the clasp 1221 can be shown in FIG20 . The clasp 1221 can include a base 1221h and an upper cover 1221i. The upper cover 1221i is rotatably connected to the base 1221h, and a gap is defined between the upper cover 1221i and the base 1221h for one end of the first watchband body 121 to pass through. A pin 1221g is provided on the surface of the upper cover 1221i facing the base 1221h, which engages with the first buckle position 1211. The detection electrode 124 is provided on the upper cover 1221i, as shown in FIG21 . One end of the flexible circuit board 125 can be fixed to the bottom shell via an adhesive layer 1251. After the upper cover 1221i and the base 1221h are assembled, the flexible circuit board 125 and the detection electrode 124 are electrically connected via a spring clip or other means.

[0132] As shown in Figure 22, one end of the first strap body 121 passes through the buckle 1221, the second strap body 122 is located on the outside, the first strap body 121 is located on the inside, and the detection electrode 124 is located on the outward side of the buckle 1221. It should be noted that when the airbag 123 is arranged on the inner side of the first strap body 121, in order to avoid the base 1221h of the buckle 1221 affecting the inflation of the airbag 123, the length of the airbag 123 will be limited to ensure that when the buckle 1221 is buckled with the first strap body 121, the airbag 123 does not extend to the buckle 1221.

[0133] It should be noted that when the structure of the clasp 1221 provided in the embodiment of the present application is as shown in FIG. 22 , the end of the first strap body 121 that is not connected to the device body 110 may not be provided with the belt loop 1213 .

[0134] 23 , after the first strap body 121 passes through the buckle 1221 , the buckle pin 1221 g can be inserted into the first buckle position 1211 of the first strap body 121 , thereby achieving the buckle engagement between the buckle 1221 and the first strap body 121 .

[0135] Another structure of the wearable device 100 provided in an embodiment of the present application is described below.

[0136] As shown in Figure 24, the difference between the embodiment of the present application and the above-mentioned embodiment is: in the embodiment of the present application, a group of strap components 120, for example, only has the first strap component 120a, as shown in Figure 24, the first strap component 120a includes a first strap body 121 and an airbag 123, and both ends of the first strap body 121 are connected to the device body 110. It should be noted that the airbag 123 in Figure 24 has not yet been fitted with the first strap body 121.

[0137] In the embodiment of the present application, as shown in FIG24 , the first end 121a of the first strap body 121 is connected to the side wall 111 of the device body 110, and the second end 121b of the first strap body 121 is slidably engaged with the device body 110. The second end 121b of the first strap body 121 is detachably connected to the first strap body 121. In the embodiment of the present application, the airbag 123 can extend from one end of the first strap body 121 to the other end. In this scenario, after the airbag 123 is inflated, the sliding position of the first strap body 121 and the device body 110 will not squeeze the airbag 123. For example, after the airbag 123 is inflated, the airbag 123 can contact the sliding position of the device body 110 and the first strap body 121 without squeezing or contacting the airbag 123. Alternatively, in some examples, the length of the airbag 123 may be less than the length of the first strap body 121. For example, one end of the airbag 123 is connected to one end of the first strap body 121 where the airflow channel 1411 (see FIG. 26 below) is provided, and the other end of the airbag 123 extends to the inner side of the sliding connection between the first strap body 121 and the device body 110 in FIG. 24 . It should be noted that due to the different thicknesses of users' wrists, the sliding length of the second end 121b of the first strap body 121 may vary. To ensure that the airbag 123 does not slide outward from the inner side of the first strap body 121, the length of the airbag 123 can be set as long as it meets the measurement requirements. For example, when the second end 121b of the first strap body 121 slides to the maximum sliding amount, the length between the first end 121a of the first strap body 121 and the sliding connection between the first strap body 121 and the device body 110 can be the length of the airbag 123.

[0138] Among them, in the embodiment of the present application, the first strap body 121 can be an inelastic woven strap. For example, the first strap body 121 can be woven by a loom, and the first strap body 121 can be a structure with terry loops on both sides. The elasticity control can be achieved by adding a proportion of hot melt wire, designing the structure of the yarn, and adding stitches on the edges of both sides of the strap to control the elasticity of the first strap component 120a.

[0139] Among them, in the embodiment of the present application, the airbag 123 can be a two-layer or multi-layer structure, and the side of the airbag 123 facing the wrist can be made of a double-layer nylon-TPU (thermoplastic polyurethane) composite film material with antibacterial function. The side of the airbag 123 facing the first strap body 121 can be a two-layer or multi-layer composite TPU nylon film material. The airbag 123 and the first strap body 121 can be connected by Velcro. For example, the Velcro can be first connected to the airbag 123 by laser welding, and then fixed to the first strap body 121 by hook and loop.

The first buffer body 1432 is located between the first lug 1431 and the side wall 111 of the device body 110. The first buffer plays a buffering role when the first lug 1431 and the device body 110 are connected.

[0143] Among them, when the third connecting structure 143 is assembled, in Figure 28, after the first buffer body 1432 is set on the first head particle 1433, see Figure 29, the first lug 1431 is installed on the first head particle 1433, and the first lug 1431 and the first head particle 1433 are locked by screws. Then, as shown in Figure 30, one end of the airbag 123 with the first air nozzle 1231 is extended into one end of the first head particle 1433, so that the first air nozzle 1231 is connected to the air flow channel 1411 of the first head particle 1433. In order to fix the airbag 123 to the first head particle 1433, as shown in Figure 31, the third connecting structure 143 also includes: a cover plate 1434 and a fastener 1435 (for example, a screw or a bolt), the cover plate 1434 is pressed on the first air nozzle 1231 of the airbag 123, and the fastener 1435 is used to fasten the cover plate 1434 to the first head particle 1433, so that the airbag 123 is fastened to the first head particle 1433.

[0144] In the embodiment of the present application, in order to achieve a sliding connection between the second end 121b of the first strap body 121 and the device body 110, as shown in Figure 25, the fourth connection structure 144 is further included. One end of the fourth connection structure 144 is connected to the device body 110 (see Figure 24), and the other end of the fourth connection structure 144 is slidably connected to the first strap body 121. The second end 121b of the fourth connection structure 144 can pass through the fourth connection structure 144 and then be connected to the first strap body 121.

[0145] 25 , the fourth connection structure 144 may include: a second lug 1442 , a second head particle 1443 and a spring lug 1444 . When assembled, as shown in FIG32 , the second head particle 1443 is connected to the second lug 1442 to form an integral structure.

[0146] As shown in FIG32 , the fourth connection structure 144 further includes a second buffer body 1441, which is disposed on the second lug 1442 and located between the second lug 1442 and the sidewall 111 of the device body 110. The second buffer body 1441 acts as a buffer between the second lug 1442 and the device body 110, preventing deformation caused by contact between the second lug 1442 and the device body 110 during assembly.

[0147] As shown in Figure 33, both ends of the spring ear 1444 are connected to the second ear 1442, and there is a sliding space between the spring ear 1444 and the second ear 1442 for the second end 121b of the first strap body 121 to bypass. The second end 121b of the first strap body 121 is slidably arranged around the spring ear 1444. In this way, when the tightness of the first strap assembly 120a needs to be adjusted, the second end 121b of the first strap body 121 can be pulled toward the first end 121a of the first strap body 121 (see Figure 24), and the first strap body 121 slides around the ear 1444. When the tightness of the first strap assembly 120a is adjusted, the second end 121b of the first strap body 121 can be pulled to any length for adjustment, and the first strap body 121 has no length limit when adjusting the tightness. Therefore, compared with the one-level and one-level adjustment of the strap in the related art, in the embodiment of the present application, the sliding cooperation between the fourth connecting structure 144 and the first strap body 121 realizes stepless adjustment of the tightness of the first strap assembly 120a.

[0148] In the embodiment of the present application, the spring ear 1444 can be a rotating shaft, and the two ends of the spring ear 1444 can be rotatably connected to the second ear 1442. In this way, when the second end 121b of the first strap body 121 is pulled, the first strap body 121 moves around the spring ear 1444, and the spring ear 1444 rotates, thereby reducing the mutual friction between the first strap body 121 and the spring ear 1444.

[0149] In the embodiment of the present application, after the first strap body 121 is adjusted in tension, an adhesive member is provided on the second end 121b of the first strap body 121 to secure the second end 121b. A connector bonded to the adhesive member is provided on the side of the first strap body 121 facing away from the airbag 123. The adhesive member and connector may be a pair of mutually adhesive and removable Velcro strips. Thus, when the second end 121b of the first strap body 121 is adjusted to a certain position based on the thickness of the wrist, the adhesive member and connector connect to the outer side of the first strap body 121, thereby securing the tension of the first strap body 121. To detach the strap, the second end 121b of the first strap body 121 can be pulled to detach from the first strap body 121.

[0150] The present application may also provide a wearable system including a terminal device and a wearable device 100, wherein the terminal device and the wearable device 100 are communicatively connected.
