[0090] The 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 worn 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.

[0091] Among them, the wearable device 100 can obtain the wearer's vital sign data through an integrated sensor. In the embodiment of the present application, the wearable device 100 has a blood pressure measurement function.

[0092] Among them, in the related art, in the wearable device with blood pressure measurement, the wearable device often includes 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.

[0093] 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 air flow channel at one end of the first strap body on the inner side of the body, and the airbag and the first strap body are assembled into an integral structure and connected to the device body. In this way, the airbag can achieve a good fit with the wrist after inflation, so that the airbag and the wrist will not be uncomfortable to wear during the wearing process and blood pressure measurement of the wearable device, thereby improving the wearing comfort of the wearable device during the wearing process and blood pressure measurement, and avoiding the end of the first strap body connected to the side wall of the device body covering the air port on the side wall of the device body when one end of the air flow channel of the first strap body is connected to the device body, so that the air port of the device body will not be exposed to the outside, thereby avoiding the problem of easy dust accumulation at the air port of the wearable device. In addition, the airbag is located on the inner side of the first strap body and does not occupy the bottom shell space of the device body, so that the device body of the wearable device is thinner when it has the blood pressure measurement function. 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 easy dust accumulation at the air port.

[0094] The specific structure of the wearable device provided in the embodiment of the present application is described in detail below.

[0095] See also Figure 1 As shown, the wearable device 100 provided in the embodiment of the present application may include: a device body 110 and at least one set of strap components 120, for example, Figure 1 In the embodiment, the number of the strap components 120 is two groups, and the two groups of strap components 120 are respectively a first strap component 120a and a second strap component 120b. Of course, in some examples, for example, the number of the strap components 120 can also be one group (see below). Fig.24 ). At least one end of each set of strap components 120 is connected to the side wall 111 of the device body 110, for example, Figure 1 In the embodiment, one end of each set of strap components 120 is connected to the side wall 111 of the device body 110. In some examples, both ends of the strap components 120 are connected to the side wall 111 of the device body 110 (see below). Fig.24 ).

[0096] Among them, see Figure 2 As shown, the device body 110 has a side wall 111, and an air port 1111 is opened on the side wall 111, wherein the side wall 111 of the device body 110 can be a ring-shaped middle frame structure, and when the strap assembly 120 is two groups, the two groups of strap assemblies 120 can be respectively connected to the two opposite side walls 111 of the device body 110.

[0097] See also Figure 3 As shown, one of the at least one set of strap components 120 may include: a first strap body 121 and an air bag 123. For example, the strap components 120 are two sets, namely a first strap component 120a and a second strap component 120b. Figure 3 As shown, the first strap assembly 120a may include a first strap body 121 and an air bag 123, see Figure 3 As shown, 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. Of course, 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 the embodiment of the present application, the inflatable airbag 123 in the first strap assembly 120a is specifically used as an example for explanation. Of course, in some examples, the airbag 123 may also be provided in both the first strap assembly 120a and the second strap assembly 120b. It should be noted that the airbag 123 in the strap assembly 120 may be in a bulging state when inflated, so as to achieve the measurement of the user's blood pressure.

[0098] The airbag 123 has an inflatable air cavity, see Figure 4A As shown, one end of the airbag 123 has a first air nozzle 1231, and one end of the first strap body 121 has an air flow channel 1411, and 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 connected to one end of the air flow channel 1411 in a detachable manner, so that 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 assembly 120a of an integral structure (see Figure 3 As shown), the inner side of the first strap component 120a is an airbag 123. When worn, the airbag 123 faces the wrist. When blood pressure is measured, the airbag 123 bulges, which can achieve a good fit with the wrist, so that there will be no wearing discomfort between the airbag 123 and the wrist during the wearing process of the wearable device and when blood pressure is measured, thereby avoiding the problem of discomfort when wearing the wearable device.

[0099] Among them, see Figure 4A As shown, 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. In this way, the airbag 123 is connected to the air port 1111. In this embodiment of the present application, in order to realize the function of blood pressure measurement, see Figure 4A As shown, it also includes: a pressure measuring component 130, which is arranged in the equipment body 110, and the pressure measuring component 130 is connected to the air port 1111, and the pressure measuring component 130 inflates the airbag 123 through the air port 1111.

[0100] Among them, see Figure 4A As shown, the pressure measuring component 130 includes: a differential pressure sensor 131, an air circuit 132 and an air pump 134. The air port 1111 is respectively 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 size of the airflow on the air circuit 132. The air pump 134 can provide an airflow, and the airflow rushes 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, and the circuit board obtains the user's blood pressure value according to the pressure difference signal obtained by the differential pressure sensor 131.

[0101] In the embodiment of the present application, in order to ensure that dust is not easily accumulated at the air port 1111 of the device body 110, the air port 1111 of the device body 110 is set to be invisible in appearance, see Figure 4A As shown, 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 port 1111, so that Figure 4B As shown, 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 port 1111 and the air port 1111 is not visible on the appearance of the device body 110, thereby avoiding the problem of dust accumulation at the air port. In addition, the airbag 123 is located on the strap assembly 120 and does not occupy the bottom shell space of the device body 110, so that the device body of the wearable device is thinner when it has the blood pressure measurement function. Therefore, the wearable device provided in the embodiment of the present application solves the problem of discomfort when the wearable device is worn during blood pressure measurement and dust accumulation at the air port.

[0102] 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 is communicated with the airbag 123 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 communicated with 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 easy dust accumulation at the air outlet.

[0103] In the embodiment of the present application, in order to realize that one end of the first strap assembly 120a is connected to the side wall 111 of the device body 110, see Figure 5A As shown, one end of the first strap body 121 has a first connection structure 141, and the first connection structure 141 has an air flow channel 1411 (see Figure 4A or the following Figure 6 As shown in FIG. 1 , one end of the first connecting structure 141 is connected to the first strap body 121, and the other end of the first connecting structure 141 is detachably connected to the side wall 111 of the device body 110. Figure 5A and Figure 5B As shown, the first air nozzle 1231 of the airbag 123 is connected to the first connecting structure 141, and the first air nozzle 1231 is connected to the air port 1111 through the air flow 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 one end of the first connecting structure 141 can be integrated with the first strap body 121 by process molding or assembly.

[0104] 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 buckling. Therefore, one of the first strap body 121 and the airbag 123 is provided with a buckling strip 1233, and the other of the strap body and the airbag 123 is provided with a groove 1214 that buckles with the buckling strip 1233. For example, see Figure 5C As shown, the airbag 123 is provided with a buckling strip 1233, and the first strap body 121 is provided with a slot 1214 buckled with the buckling strip 1233. Of course, in some examples, the structure of the buckling strip 1233 is not limited to Figure 5C The bar shapes shown, see for example Figure 5D As shown, the buckling strip 1233 provided on the airbag 123 may be mushroom-shaped, and the first strap body 121 is provided with a slot 1214 buckled with the mushroom-shaped buckling strip 1233 .

[0105] In the embodiment of the present application, the first strap body 121 and the airbag 123 are engaged with each other through the buckle strip 1233 and the slot 1214, so as to achieve a good fit between the strap assembly 120 and the airbag 123, improve the wearing comfort, save space, and solve the problem of uncomfortable wearing caused by the lack of fit between the strap and the airbag 123 during wearing.

[0106] In one possible implementation, see Figure 6 and Figure 7 As shown, 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.

[0107] In a possible implementation, in order to realize the detachable connection between the first strap assembly 120a and the device body 110, see Fig. 8A As shown, it also includes: a first control button 150, see Figure 8BAs shown, 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 disassembly 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 disassembled. When the first strap assembly 120a needs to be disassembled from the device body 110, the first control button 150 is pressed to release the connection between the first connection structure 141 and the device body 110. In this way, there is no connection relationship between the first strap assembly 120a and the device body 110, and the first strap assembly 120a can be disassembled from the device body 110. In this way, on the one hand, the detachable connection between the strap assembly 120 and the device body 110 is realized, and on the other hand, more functional straps can be compatible, so that the wearable device 100 becomes a multifunctional smart strap, not limited to blood pressure measurement.

[0108] The first control button 150 controls the first connection structure 141 to be connected or disconnected from the device body. Fig. 8A As shown, 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. Figure 8B As shown, 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 (such as Figure 8B For example, the user applies pressure to the pressing portion 1511. Figure 8B When a force is applied in the direction of the arrow in the figure, the first control button 150 moves in the direction indicated by the arrow, the elastic member 152 is compressed, and 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 of the first control button 150 and the elastic member 152 are located in the device body 110.

[0109] See also Figure 8C As shown, 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. Figure 8C and Figure 8B As shown, the pressing portion 1511 of the button body 151 (see Figure 8C ) is located at the edge of the bottom shell 114 of the device body 110, see Fig. 9As shown, the clamping portion 1512 is used to cooperate with the clamping slot 141a provided on the first connecting structure 141 to connect the first connecting structure to the device body 110. When the first strap assembly 120a needs to be disassembled from the device body 110, a force is applied to the pressing portion 1511. Fig. 9 The pressing portion 1511 moves along the arrow direction, and drives the clamping portion 1512 to move along the arrow direction, so that the clamping portion 1512 is separated from the clamping groove 141a on the first connecting structure 141, and the first control button 150 is separated from the first connecting structure 141, and the first strap assembly 120a can 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 to move in the opposite direction of the arrow direction to achieve reset.

[0110] 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 snap-on part 1512 move upward a certain distance along the arrow. After one end of the first connecting structure 141 where the snap-in slot 141a is set is inserted into the device body 110, an external force is applied to the pressing part 1511 to make the snap-on part 1512 snap into the snap-in slot 141a. Alternatively, a guide surface (not shown) can be provided at one end of the first connecting structure 141 where the snap-in slot 141a is set. When the first connecting structure 141 is inserted into the device body 110, the snap-on part 1512 is driven to move along the direction of the arrow until the snap-on part 1512 snaps into the snap-in slot 141a and is assembled into place, thereby realizing the connection between the first connecting structure 141 and the first control button 150.

[0111] In the embodiment of the present application, the first strap assembly 120a is provided with an airbag 123, and the second strap assembly 120b is not provided with an airbag 123. Fig. 9 As shown, 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, and the buckle 1221 is used to be detachably connected to one end of the first strap body 121.

[0112] When worn, the first strap body 121 and the second strap body 122 are detachably connected via the buckle 1221. Fig.10 As shown, the first strap body 121 is provided with a plurality of first buckle positions 1211 arranged at intervals, see Fig.11 As shown, the first buckle position 1211 is used to buckle with the buckle 1221. In this way, after the first strap body 121 and the second strap body 122 are buckled, the second strap body 122 is located outside the first strap body 121, and the second strap body 122 does not interfere with the airbag 123.

[0113] In the embodiment of the present application, in order to ensure that the airbag 123 has more fitting positions with the wrist, see Fig.10 As shown, the length of the first strap body 121 is greater than that of the second strap body 122, and the airbag 123 extends from 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 relatively large, and when the second strap body 122 cooperates 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 the wrist is greater, thereby achieving a larger area of ​​fitting between the airbag 123 and the wrist, ensuring accurate blood pressure detection.

[0114] Among them, in the embodiments of this application, see Fig.10 As shown, 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, and 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 buckled with the first buckle position 1211 of the first strap body 121.

[0115] In the embodiment of the present application, in order to make the buckle between the first strap body 121 and the second strap body 122 more stable, see Fig.10 As shown, a buckle 1212 is provided on the outer side of the first strap body 121 (ie, the side facing away from the airbag 123), and a plurality of second buckle positions 1222 are provided on the second strap body 122. Fig.11 As shown, the buckle 1212 is used to buckle and connect with the second buckle position 1222. After the first strap body 121 and the second strap body 122 are buckled together, Fig.12 As shown, 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.

[0116] In the embodiment of the present application, one structure of the buckle 1221 can be seen in Fig.13 As shown, the clasp 1221 may include: a clasp cover 1221a, on which a fixing column 1221c and a movable sliding buckle 1221b are provided, wherein the fixing column 1221c is used to cooperate with one of the first buckle positions 1211, and the sliding buckle 1221b is used to engage with another first buckle position 1211. Fig.14As shown, the clasp cover 1221a may include an upper shell 1221d and a lower shell 1221e, wherein a fixing column 1221c is provided on the lower shell 1221e, a movable slider 1221f is provided between the upper shell 1221d and the lower shell 1221e, a sliding buckle 1221b is provided at one end of the slider 1221f, and the slider 1221f is slidably set in the clasp cover 1221a through a spring 1221j.

[0117] When wearing, see Fig.15A As shown, first, one end of the slider 1221f can be pushed (moved along the -x direction), the spring 1221j is compressed, and the slider 1221f drives the sliding buckle 1221b to move to the left, so that the sliding buckle 1221b can extend into the first buckle position 1211 of the first strap, and the slider 1221f is released. The slider 1221f moves along the x direction under the elastic force of the spring 1221j, and the sliding buckle 1221b moves to the right. The end of the sliding buckle 1221b is stuck on the edge of the first buckle position 1211, so that the sliding buckle 1221b realizes the limiting effect on the first strap body 121 in the x direction and the z direction. Among them, the fixed column 1221c extends into another first buckle position 1211, and the fixed column 1221c plays a positioning role in the x direction. In the embodiment of the present application, a dual positioning effect in the x-direction is achieved through the fixed column 1221c and the movable sliding buckle 1221b, so that a stable snap-fitting effect is achieved between the buckle 1221 and the first strap body 121.

[0118] 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 realized in the smallest space. In addition, the convenience of opening and closing of the two strap bodies and the aesthetics of the buckle 1221 are achieved.

[0119] 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 are both plastic straps.

[0120] Among them, when the first strap body 121 and the second strap body 122 are both plastic straps, during the blood pressure measurement process, the tensile deformation of the strap body has a greater impact on the airbag 123. Therefore, in the embodiment of the present application, the inner side of the first strap body 121 and the second strap body 122 is provided with a tensile interlayer 126, for example, see Fig. 15B As shown, the inner side of the first strap body 121 is provided with a tensile interlayer 126. 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 also be provided in the first strap body 121 and the second strap body 122, for example, see Fig. 15C As shown, a tensile-resistant interlayer 126 is provided inside the first strap body 121 .

[0121] By setting the tensile 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, it will not affect the airbag 123, thereby ensuring the accuracy of the blood pressure measurement.

[0122] It should be noted that the tensile interlayer 126 may be an interlayer made of a material with high tensile strength, for example, the material with high tensile strength may be polyimide (PI) or the material with high tensile strength may be nylon.

[0123] When the tensile interlayer 126 is provided in the first strap body 121 and the second strap body 122, it can be integrally formed with the material with high tensile strength during the molding process of the first strap body 121 and the second strap body 122. For example, the material of the first strap body 121 and the second strap body 122 can be rubber. The rubber is first molded once. During the molding, a middle plate is placed between two pieces of rubber. The middle plate has positioning columns for positioning the film material. After the molding, the middle plate is taken out from the rubber, and the whole is molded again to integrate the material with high tensile strength with the rubber. The tensile resistance of the first strap body 121 and the second strap body 122 after molding is greatly improved. When the first strap body 121 and the second strap body 122 are pulled, the tensile interlayer 126 in the first strap body 121 and the second strap body 122 bears the tensile force, and the deformation of the first strap body 121 and the second strap body 122 is controlled within a small range.

[0124] 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, Fig.16 As shown, the buckle 1221 is also provided with a detection electrode 124, and the second strap body 122 is provided with a flexible circuit board 125, see Fig.17 As shown, the detection electrode 124 is electrically connected to the circuit board (not shown) in the device body 110 through the flexible circuit board 125. The detection electrode 124 can be exposed on the buckle 1221, and the detection electrode 124 can be a sensor. The detection electrode 124 can be attached to the leg or chest of the human body to complete the measurement of heartbeat or body fat, etc. In the embodiment of the present application, by setting the detection electrode 124 on the buckle 1221, the function of the wearable device 100 is increased, and the purpose of human body contact sensor and improving the accuracy of electrocardiogram measurement is achieved.

[0125] 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, see Fig.18 As shown, 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.

[0126] In order to realize the card detachable connection between the second strap body 122 and the device body 110, the second control button 160 (see the above Fig. 9 ), the second control button 160 is provided on the device body 110, and the second control button 160 is used to control the second connection structure 142 to be connected to or disconnected from the device body 110. The structure and function principle of the second control button 160 can refer to the above Fig. 8A The first control button 150 in the embodiment, for example, the second control button 160 may include: a button body 151 and an elastic member 152, wherein the button body 151 has a pressing portion 1511 and two clamping portions 1512 respectively located on both sides of the pressing portion 1511. The second connecting structure 142 is provided with a clamping groove 142a that cooperates with the clamping portion 1512 of the second control button 160, and the cooperation between the second control button 160 and the second connecting structure 142 can refer to the above-mentioned first control button 150 and the first connecting structure 141, and will not be repeated in the embodiment of the present application.

[0127] When the detection electrode 124 is provided on the clasp 1221, in order to realize the signal transmission between the detection electrode 124 and the device body 110, therefore, see Fig.18 As shown, the second connection structure 142 is provided with a conductive contact 1421, the conductive contact 1421 is electrically connected to the flexible circuit board 125, and the surface of the device body 110 connected to the second connection structure 142 is provided with a conductive terminal 113 electrically in contact with the conductive contact 1421 (see Fig.17 ), the conductive terminal 113 is electrically connected to the circuit board in the device body 110, so that 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 conductive, and the detection electrode 124 is conductive with the circuit board in the device body 110 through the flexible circuit board 125, thereby realizing signal transmission.

[0128] It should be noted that in the embodiments of the present application, Fig.17 In the embodiment, the detection electrode 124 is disposed on the buckle 1221. In some examples, other detection electrodes 124 may be disposed 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.

[0129] When the detection electrode 124 is disposed on the buckle 1221, Fig.19 As shown, a mounting groove can be set on one side of the buckle 1221, and the detection electrode 124 is set in the mounting groove.

[0130] In the embodiment of the present application, another structure of the buckle 1221 can be as follows Fig. 20 As shown, the clasp 1221 may include: a base 1221h and an upper cover 1221i, the upper cover 1221i is rotatably connected to the base 1221h, and there is a gap between the upper cover 1221i and the base 1221h for one end of the first strap body 121 to pass through, and a clasp 1221g is provided on the surface of the upper cover 1221i facing the base 1221h to engage with the first clasp 1211. Among them, the detection electrode 124 is provided on the upper cover 1221i, see Fig.21 As shown, one end of the flexible circuit board 125 can be fixed on the bottom shell through the 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 through a spring or the like.

[0131] See also Fig. 22 As shown, 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 bulging 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.

[0132] It should be noted that the structure of the clasp 1221 provided in the embodiment of the present application is Fig. 22 As shown, the end of the first strap body 121 that is not connected to the device body 110 may not be provided with the strap loop 1213 .

[0133] See also Fig.23 As shown, after the first strap body 121 passes through the buckle 1221, the buckle pin 1221g can be inserted into the first buckle position 1211 of the first strap body 121, so as to realize the buckle engagement between the buckle 1221 and the first strap body 121.

[0134] Another structure of the wearable device 100 provided in an embodiment of the present application is described below.

[0135] See also Fig.24 As shown, the difference between the embodiment of the present application and the above embodiment is that: in the embodiment of the present application, a group of strap components 120, for example, only the first strap component 120a, see Fig.24 As shown, the first strap assembly 120a includes a first strap body 121 and an air bag 123. Both ends of the first strap body 121 are connected to the device body 110. It should be noted that: Fig.24 The middle air bag 123 has not yet been fitted with the first strap body 121 .

[0136] In the present application examples, see Fig.24 As shown, the first end 121a of the first strap body 121 is connected to the side wall 111 of the device body 110, the second end 121b of the first strap body 121 is slidably matched with the device body 110, and 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, but there will be no squeezing or no contact with the airbag 123. Alternatively, in some examples, the length of the airbag 123 can be less than the length of the first strap body 121. For example, one end of the airbag 123 and the first strap body 121 are provided with an airflow channel 1411 (see below) Fig.26 ) is connected to one end, and the other end of the airbag 123 extends to Fig.24 The inner side position of the first strap body 121 and the device body 110 where they are slidably connected. It should be noted that, due to the different thicknesses of the user's wrist, the sliding length of the second end 121b of the first strap body 121 will be different. In order to ensure that the airbag 123 does not slide out from the inner side of the first strap body 121 to the outer side of the first strap body 121, when setting the length of the airbag 123, it is sufficient to meet 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 position between the first strap body 121 and the device body 110 can be the length of the airbag 123.
