[0018] The present application is further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0019] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] See also Figures 1 to 3 , Figure 1 is a schematic diagram of the structure of a wearable device 10 provided in an embodiment of the present application, Figure 2 yes Figure 1 A schematic diagram of the structure of the airbag assembly 220, Figure 3 yes Figure 2 Schematic diagram of the exploded structure of the airbag assembly 220.

[0021] The wearable device 10 provided in the embodiment of the present application may be a smart watch, a smart bracelet, or a cuff-type blood pressure monitor, etc., and the following is only an example of the wearable device 10 being a smart watch. Figure 1 As shown, the wearable device 10 may include: a device body 100 and a strap mechanism 200. Among them, the device body 100 can be connected to the strap mechanism 200, and can be enclosed together with the strap mechanism 200 to form a wearing space 101, and the user can wear the device body 100 and the strap mechanism 200 on the wrist through the wearing space 101. At the same time, the strap mechanism 200 can also expand or contract under the control of the device body 100, so as to compress the blood vessels in the user's wrist when expanded, and cooperate with the device body 100 to measure the user's blood pressure. In this embodiment, the side of the strap mechanism 200 that contacts the user's wrist can have the advantage of high breathability, which helps to reduce sweat accumulation between the user's wrist and the strap mechanism 200, thereby improving the comfort of the user wearing the wearable device 10.

[0022] Exemplarily, when the wearable device 10 is a smart watch, the device body 100 can be the watch head of the smart watch, and the device body 100 can not only provide users with communication services such as voice calls and video chats, but also monitor the user's daily exercise conditions, physical health conditions and other data indicators. For example, the device body 100 can be provided with functional devices such as an air pump, a display screen, a camera, a speaker, a microphone, a gravity sensor, an inertial sensor, a PPG (Photo Plethysmo Graphy) sensor, and an ECG (Electro Cardio Graphy) sensor to achieve the aforementioned functions of the device body 100. In this embodiment, the air pump in the device body 100 can be connected to the strap mechanism 200, and can inflate and deflate the strap mechanism 200 to control the expansion or contraction of the strap mechanism 200. Optionally, the air pump in the device body 100 can also be replaced with a liquid pump, so that the liquid pump is used to inject or extract liquid into the strap mechanism 200, thereby achieving control of the expansion or contraction of the strap mechanism 200.

[0023] The strap mechanism 200 can be connected to two opposite sides of the device body 100, and can be arranged together with the device body 100 to form a wearing space 101. Figure 1 As shown, the strap mechanism 200 may include: a strap assembly 210 and an airbag assembly 220. Among them, the strap assembly 210 can be connected to the opposite sides of the device body 100, and can be enclosed together with the device body 100 to form the aforementioned wearing space 101. The airbag assembly 220 can be arranged on the side of the strap assembly 210 facing the wearing space 101, and connected to the air pump in the device body 100, and the airbag assembly 220 can expand or contract under the control of the device body 100 to compress the blood vessels in the user's wrist, thereby cooperating with the device body 100 to measure the user's blood pressure. In this embodiment, the side of the airbag assembly 220 that contacts the user can have the advantage of high air permeability, which helps to reduce the accumulation of sweat between the user's wrist and the airbag assembly 220, thereby improving the comfort of the user wearing the wearable device 10.

[0024] For example, when the wearable device 10 is a smart watch, the strap assembly 210 may be a strap of the smart watch, and the strap assembly 210 may include: a strap body 211 and a connector 212. Figure 1As shown, one end of the strap body 211 can be fixedly or detachably connected to one side of the device body 100, and the other end of the strap body 211 can pass through the connecting ring 110 on the other opposite side of the device body 100, and be bent and sleeved on the connecting ring 110, so that the device body 100 can be enclosed together with the strap body 211 to form the aforementioned wearing space 101. The connecting member 212 can be provided on the other end of the strap body 211 passing through the connecting ring 110, and the connecting member 212 can be detachably connected to the matching portion 213 on the side of the strap body 211 away from the wearing space 101 after the other end of the strap body 211 is bent, so as to fix the position of the other end of the strap body 211. In this embodiment, the connecting member 212 and the matching portion 213 can specifically be Velcro. Alternatively, the connecting member 212 and the matching portion 213 can also be metal buckles and buckle positions, respectively. Of course, the types of the connecting member 212 and the matching portion 213 are also not limited to this, and this embodiment is not repeated here one by one.

[0025] Optionally, in addition to the above-mentioned use of a single strap body 211 and the device body 100 to enclose the wearing space 101, two strap bodies 211 and the device body 100 can also be used to enclose the wearing space 101. For example, the opposite sides of the device body 100 can be fixedly or detachably connected to one end of the two strap bodies 211, and the other ends of the two strap bodies 211 can be connected to each other, so that the device body 100 can be enclosed with the two strap bodies 211 to form the wearing space 101. For example, the other ends of the two strap bodies 211 can be respectively provided with a connecting piece 212 and a matching portion 213, so as to be detachably connected using the connecting piece 212 and the matching portion 213. In this embodiment, the airbag assembly 220 can cover the side of any one of the two strap bodies 211 facing the wearing space 101, or cover the side of the two strap bodies 211 facing the wearing space 101. It is only necessary for the airbag assembly 220 to be located in the wearing space 101 and to be able to compress the user's wrist to realize the blood pressure measurement function.

[0026] The airbag assembly 220 is disposed on the side of the strap body 211 facing the wearing space 101, and is connected to the side of the device body 100 connected to the strap body 211, and the airbag assembly 220 is also connected to the air pump in the device body 100, so that the airbag assembly 220 can expand or contract under the control of the device body 100. Figures 2 to 3As shown, the airbag assembly 220 may include: an airbag body 221 and a mesh sleeve 222. The airbag body 221 is arranged on the side of the strap body 211 facing the wearing space 101, and the part of the airbag body 221 close to the strap body 211 is also connected to the side of the device body 100 connected to the strap body 211, and is connected to the air pump in the device body 100, so that the airbag body 221 can expand or contract under the control of the device body 100. At the same time, the mesh sleeve 222 can cover the part of the airbag body 221 away from the strap body 211 to isolate the airbag body 221 and the user's wrist to play a role in ventilation and sweat prevention. In addition, the mesh sleeve 222 is also provided with an opening 2221 on the side facing the strap body 211, and the mesh sleeve 222 can not only be set on the airbag body 221 through the opening 2221, but also can be detached from the airbag body 221 through the opening 2221.

[0027] After long-term research by the inventor, it is found that some technical solutions increase the air permeability between the airbag body 221 and the user's wrist by providing an air-permeable pad on the side of the airbag body 221 that contacts the user. The air-permeable pad is often fixed to the airbag body 221 by welding or sewing, and other non-detachable methods. When replacing the air-permeable pad, the user needs to simultaneously remove the airbag body 221 from the device body 100, which not only increases the difficulty of removing the air-permeable pad for the user, but also increases the cost required for the user to replace the air-permeable pad.

[0028] Based on the above technical problems, the embodiment of the present application sets a mesh 222 to cover the partial area of ​​the airbag body 221 away from the strap body 211, so that the mesh 222 can isolate the airbag body 221 and the user's wrist to play a role of ventilation and sweat prevention, thereby improving the comfort of the user wearing the wearable device 10. At the same time, by setting an opening 2221 on the side of the mesh 222 facing the strap body 211, and the mesh 222 can also be set on the airbag body 221 through the opening 2221, or detached from the airbag body 221, and the partial area of ​​the airbag body 221 close to the strap body 211 is used to connect the air pump of the device body 100, so that even if the airbag body 221 and the device body 100 are in a connected state, the mesh 222 can still be directly detached from the airbag body 221 without being restricted by the connection between the airbag body 221 and the device body 100, which is conducive to improving the convenience of users replacing the mesh 222.

[0029] All directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0030] Please combine Figure 3 See also Figures 4 to 7 , Figure 4 yes Figure 2 A schematic diagram of a partial cross-sectional structure of the middle airbag assembly 220 along V-V, Figure 5 yes Figure 3 Schematic diagram of the connection structure between the first diaphragm 2211 and the mesh sleeve 222, Figure 6 yes Figure 2 A schematic diagram of a partial cross-sectional structure of the middle airbag assembly 220 along VI-VI, Figure 7 yes Figure 2 Schematic diagram of the partial cross-sectional structure of the middle airbag assembly 220 along IV-IV.

[0031] The airbag body 221 is disposed on the side of the strap body 211 facing the wearing space 101, and the airbag body 221 is also connected to the device body 100, and can expand or contract under the control of the device body 100. Figure 3 to Figure 4As shown, the airbag body 221 may include: a first diaphragm 2211 and a second diaphragm 2212. The first diaphragm 2211 is arranged in the mesh 222 and can stretch the mesh 222 so that the mesh 222 can remain flat under the support of the first diaphragm 2211 to reduce the probability of large wrinkles in the mesh 222. The second diaphragm 2212 is arranged on the side of the strap body 211 facing the wearing space 101 and is located between the mesh 222 and the strap body 211, and the side of the mesh 222 facing the second diaphragm 2212 has an opening 2221. At the same time, the first diaphragm 2211 is also connected to the second diaphragm 2212, and a conducting portion 2213 is formed to connect the first diaphragm 2211 and the second diaphragm 2212, and the opening 2221 can also avoid the conducting portion 2213. In addition, the second diaphragm 2212 is also connected to the device body 100, and the second diaphragm 2212 is also connected to the air pump of the device body 100, so that the device body 100 can inflate and deflate the first diaphragm 2211 and the second diaphragm 2212 to control the expansion or contraction of the first diaphragm 2211 and the second diaphragm 2212. In this embodiment, the first diaphragm 2211 can be a part of the airbag body 221 away from the strap body 211, and the second diaphragm 2212 can be a part of the airbag body 221 close to the strap body 211.

[0032] Through the above arrangement, when the user wears the wearable device 10, the mesh sleeve 222 can isolate the first diaphragm 2211 and the user's wrist to play a role of breathability and sweat prevention, thereby improving the user's wearing comfort. At the same time, by setting the second diaphragm 2212 to be connected to the device body 100, and the device body 100 can indirectly inflate and deflate the first diaphragm 2211 through the second diaphragm 2212, the first diaphragm 2211 can be set independently of the device body 100, so that the mesh sleeve 222 can cover the first diaphragm 2211 more completely without the need to avoid the connection design of the first diaphragm 2211 and the device body 100. In addition, the independent design of the first diaphragm 2211 enables the mesh sleeve 222 to be directly detached from the first diaphragm 2211 even when the second diaphragm 2212 and the device body 100 are in a connected state, without the need to remove the airbag body 221 as a whole from the device body 100, which is conducive to improving the convenience of users replacing the mesh sleeve 222.

[0033] The terms "first", "second", and "third" in this application are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features.

[0034] Exemplarily, the first diaphragm 2211 is disposed in the mesh sleeve 222, and the first diaphragm 2211 includes: a first sub-diaphragm 2211a and a second sub-diaphragm 2211b. Figures 3 to 5 As shown, the first sub-diaphragm 2211a and the second sub-diaphragm 2211b are stacked and located between the second sub-diaphragm 2211b and the second diaphragm 2212, and the first sub-diaphragm 2211a and the second sub-diaphragm 2211b are also enclosed together to form a first cavity 2201. At the same time, the first sub-diaphragm 2211a is connected to the second diaphragm 2212, and the aforementioned conductive portion 2213 is formed, and the first sub-diaphragm 2211a is also provided with a first vent c connecting the conductive portion 2213 and the first cavity 2201. The device body 100 can inflate and deflate the first cavity 2201 through the second diaphragm 2212, the conductive portion 2213 and the first vent c, so that the first diaphragm 2211 expands or contracts.

[0035] Optionally, the edge positions of the first sub-membrane 2211a and the second sub-membrane 2211b can be connected by heat-melting, so that the first sub-membrane 2211a and the second sub-membrane 2211b can be jointly enclosed to form the first cavity 2201, and the heat-melting connection method is also conducive to improving the sealing of the first cavity 2201. Of course, the connection method of the first sub-membrane 2211a and the second sub-membrane 2211b is also not limited to this, as long as the first sub-membrane 2211a and the second sub-membrane 2211b can be enclosed to form the first cavity 2201, and this embodiment does not limit this.

[0036] The second membrane 2212 is located on the side of the mesh sleeve 222 having the opening 2221 and between the mesh sleeve 222 and the strap body 211. The second membrane 2212 is also connected to the strap body 211 and the first sub-membrane 2211a. Figure 3 to Figure 4 As shown, the second diaphragm 2212 may include: a third sub-diaphragm 2212a and a fourth sub-diaphragm 2212b. The third sub-diaphragm 2212a and the fourth sub-diaphragm 2212b are stacked and located between the first sub-diaphragm 2211a and the fourth sub-diaphragm 2212b, and the third sub-diaphragm 2212a and the fourth sub-diaphragm 2212b are also jointly surrounded to form a second cavity 2202 connected to the device body 100. At the same time, the third sub-diaphragm 2212a is connected to the first sub-diaphragm 2211a and forms the aforementioned conductive portion 2213, and the third sub-diaphragm 2212a is also provided with a second air hole d connecting the conductive portion 2213 and the second cavity 2202, so that the device body 100 can not only inflate and discharge air to the second cavity 2202, but also inflate and discharge air to the first cavity 2201 through the second air hole d, the conductive portion 2213 and the first air hole c, so as to realize the expansion or contraction of the first diaphragm 2211 and the second diaphragm 2212.

[0037] Optionally, the edge positions of the third sub-diaphragm 2212a and the fourth sub-diaphragm 2212b can also be connected by heat-melting, so that the third sub-diaphragm 2212a and the fourth sub-diaphragm 2212b can be jointly enclosed to form the second cavity 2202, and the heat-melting connection method is also conducive to improving the sealing of the second cavity 2202. Of course, the connection method of the third sub-diaphragm 2212a and the fourth sub-diaphragm 2212b is also not limited to this, as long as the third sub-diaphragm 2212a and the fourth sub-diaphragm 2212b can be enclosed to form the second cavity 2202, and this embodiment does not limit this.

[0038] Optionally, the third sub-membrane 2212a and the area corresponding to the opening 2221 of the first sub-membrane 2211a can also be hot-melt connected, so that a conductive portion 2213 can be formed between the first sub-membrane 2211a and the third sub-membrane 2212a, and the conductive portion 2213 can be an annular convex edge formed by the corresponding area of ​​the first sub-membrane 2211a or the second sub-membrane 2211b being hot-pressed, and can be surrounded between the third sub-membrane 2212a and the first sub-membrane 2211a to form a sealed space e, and the first air hole c and the second air hole d can be connected to the sealed space e. That is, the area of ​​the first sub-membrane 2211a exposed in the sealed space e can be provided with the first air hole c, and the area of ​​the third sub-membrane 2212a exposed in the sealed space e can be provided with the second air hole d. Such a setting is conducive to improving the sealing of the connection between the first sub-membrane 2211a and the third sub-membrane 2212a.

[0039] Optionally, the third sub-diaphragm 2212a and the first sub-diaphragm 2211a can also be connected in other ways. For example, the third sub-diaphragm 2212a and the first sub-diaphragm 2211a corresponding to the opening 2221 can also be bonded by a sealant, and the first air hole c and the second air hole d are respectively provided, and the first air hole c and the second air hole d can be coaxially provided to connect the first cavity 2201 and the second cavity 2202. At this time, the area where the third sub-diaphragm 2212a and the first sub-diaphragm 2211a are bonded can jointly constitute the aforementioned conductive part 2213, and the first air hole c and the second air hole d are equivalent to being provided on the conductive part 2213, so as to realize the connection of the conductive part 2213 to the first cavity 2201 and the second cavity 2202.

[0040] Optionally, the conductive portion 2213 may be an annular convex edge formed by heat pressing the corresponding area of ​​the first sub-membrane 2211a or the third sub-membrane 2212a, or it may be a structural member independent of the first sub-membrane 2211a and the third sub-membrane 2212a, and may be connected to the first sub-membrane 2211a and the second sub-membrane 2211b respectively by hot-melt connection or bonding, and may connect the first cavity 2201 and the second cavity 2202. This embodiment is not limited to this.

[0041] Optionally, the number of the first air holes c and the second air holes d can be multiple, and the multiple first air holes c and the multiple second air holes d can be arranged in sequence along the length direction of the airbag body 221 in the flattened state. Among them, the number of the first air holes c and the second air holes d can be the same, and the multiple first air holes c and the multiple second air holes d can also be arranged one by one. In addition, the apertures of the multiple first air holes c can be the same or different, the apertures of the multiple second air holes d can also be the same or different, and the apertures of the corresponding first air holes c and the second air holes d can be the same. It can be understood that the aforementioned arrangement of the first air holes c and the second air holes d is only an exemplary description, and the specific arrangement mode, corresponding relationship and aperture size of the first air holes c and the second air holes d can also be adaptively adjusted according to design requirements, and this embodiment does not limit this. In the description of this application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0042] For example, in order to achieve the communication between the second cavity 2202 and the air pump in the device body 100, the third sub-diaphragm 2212a is further provided with a first extension portion 2212c, and the fourth sub-diaphragm 2212b is further provided with a second extension portion 2212d. Figure 3 and Figure 6 As shown, the first extension part 2212c is connected to the end of the third sub-diaphragm 2212a, the second extension part 2212d is connected to the end of the fourth sub-diaphragm 2212b, and the first extension part 2212c and the second extension part 2212d can be stacked and jointly enclose a first air guide space f that is connected to the second cavity 2202. At the same time, the first extension part 2212c and the second extension part 2212d can jointly constitute the air guide end 2212e of the second diaphragm 2212, and the air guide end 2212e can be connected to the device body 100, and can be inserted into the air guide structure (connected to the air pump) on the device body 100, or the air guide structure (connected to the air pump) on the device body 100 is inserted, so that the first air guide space f can connect the device body 100 and the second cavity 2202, thereby realizing the device body 100 to charge and discharge the second cavity 2202.

[0043] Optionally, the edge positions of the first extension portion 2212c and the second extension portion 2212d may also be connected by heat-melting, so that the first extension portion 2212c and the second extension portion 2212d can be jointly enclosed to form the first air guide space f, and the heat-melting connection method is also conducive to improving the sealing of the first air guide space f. Of course, the connection method of the first extension portion 2212c and the second extension portion 2212d may not be limited to this, as long as the first extension portion 2212c and the second extension portion 2212d can be enclosed to form the first air guide space f, and this embodiment does not limit this.

[0044] Optionally, the airbag assembly 220 may further include: a first air nozzle 223 disposed on the air guide end 2212e. The first air nozzle 223 may be disposed on the first extension portion 2212c and / or the second extension portion 2212d, and the first air nozzle 223 may also be inserted into the air guide structure on the device body 100, and respectively connect the air pump and the first air guide space f. For example, the first air nozzle 223 may be provided through the second extension portion 2212d to connect the first air guide space f, and the first air nozzle 223 may also be provided protruding from the side of the second extension portion 2212d away from the first extension portion 2212c, so that the first air nozzle 223 can be inserted into the air guide structure from the side of the device body 100 toward the wearing space 101, so as to connect the first air guide space f and the air pump. Similarly, the first air nozzle 223 can also be inserted into the first extension portion 2212c to connect to the first air guide space f, and the first air nozzle 223 can also protrude from the side of the first extension portion 2212c away from the second extension portion 2212d, so that the first air nozzle 223 can be inserted into the air guide structure from the side of the device body 100 away from the wearing space 101.

[0045] In addition, the first air nozzle 223 can be inserted into the air guide structure from the side of the device body 100 away from or toward the wearing space 101, and can also be inserted into the air guide structure from the side where the device body 100 is connected to the strap 211. For example, one end of the first air nozzle 223 can be wrapped by the first extension portion 2212c and the second extension portion 2212d, which is equivalent to being arranged on the first extension portion 2212c and the second extension portion 2212d, and the other end can extend outward from the first air guide space f along the length direction of the airbag body 221. In this way, when the first air nozzle 223 is assembled with the device body 100, the other end of the first air nozzle 223 can be inserted into the air guide structure from the side where the device body 100 is connected to the strap 211, so as to achieve the communication between the first air guide space f and the air pump in the device body 100. Of course, in addition to the above arrangement, the specific arrangement position of the first air nozzle 223 can also be adaptively adjusted according to the direction and position of assembly with the device body 100, and this embodiment does not limit this.

[0046] Optionally, in addition to the second cavity 2202, the second diaphragm 2212 also has a third cavity 2203 that is independent of the second cavity 2202, and the third cavity 2203 is also located on the side of the second cavity 2202 away from the first cavity 2201. At the same time, after the device body 100 inflates the first cavity 2201 and the second cavity 2202, the device body 100 can also inflate the third cavity 2203, so that the second diaphragm 2212 can expand twice, so as to compress the user's wrist through the two expansions, so as to improve the accuracy of the wearable device 10 in measuring blood pressure. Figure 3 to Figure 4 As shown, the second diaphragm 2212 may also include: a fifth sub-diaphragm 2212f. The fifth sub-diaphragm 2212f is arranged on the side of the fourth sub-diaphragm 2212b away from the third sub-diaphragm 2212a, and is jointly surrounded with the fourth sub-diaphragm 2212b to form a third cavity 2203 independent of the second cavity 2202. At the same time, the device body 100 can be connected to the third cavity 2203, and can inflate and deflate the third cavity 2203 to independently control the expansion or contraction of the second diaphragm 2212. In this embodiment, the first cavity 2201 can be arranged away from the strap body 211, the third cavity 2203 can be arranged close to the strap body 211, and the second cavity 2202 is located between the first cavity 2201 and the third cavity 2203. Through the above arrangement, the second cavity 2202 and the third cavity 2203 can share the fourth sub-diaphragm 2212 b , which is beneficial to reducing the overall thickness of the airbag body 221 .

[0047] Optionally, in addition to the solution of sharing the fourth sub-diaphragm 2212b, the second diaphragm 2212 may further include: a sixth sub-diaphragm, and the sixth sub-diaphragm may be arranged on the side of the fifth sub-diaphragm 2212f away from the fourth sub-diaphragm 2212b, and may be jointly arranged with the fifth sub-diaphragm 2212f to form the third cavity 2203. In this case, the fifth sub-diaphragm 2212f may be stacked with the fourth sub-diaphragm 2212b, but may not be jointly arranged with the fourth sub-diaphragm 2212b to form the third cavity 2203.

[0048] Exemplarily, in order to achieve the communication between the third cavity 2203 and the air pump in the device body 100, the fifth sub-diaphragm 2212f is further provided with a third extension portion 2212g, and the third sub-diaphragm 2212a is further provided with a fourth extension portion 2212h. Figure 3 and Figure 7As shown, the third extension part 2212g is connected to the end of the fifth sub-diaphragm 2212f, the fourth extension part 2212h is connected to the end of the third sub-diaphragm 2212a, and the third extension part 2212g and the fourth extension part 2212h can be stacked and jointly enclose a second air guide space g that is connected to the third cavity 2203. At the same time, the third extension part 2212g and the fourth extension part 2212h can jointly constitute the ventilation end 2212j of the second diaphragm 2212, and the ventilation end 2212j can be connected to the device body 100, and can be inserted into the air guide structure (connected to the air pump) on the device body 100, or the air guide structure (connected to the air pump) on the device body 100 is inserted, so that the second air guide space g can connect the device body 100 and the third cavity 2203, thereby realizing the device body 100 to charge and discharge the third cavity 2203. In this embodiment, the ventilation end 2212j and the gas guiding end 2212e can be arranged adjacent to each other and connected to the same side of the device body 100 to improve the assembly convenience of the airbag body 221 and the device body 100.

[0049] Optionally, the edge positions of the third extension portion 2212g and the fourth extension portion 2212h can also be connected by heat melting, so that the third extension portion 2212g and the fourth extension portion 2212h can be jointly enclosed to form the second air guide space g, and the heat melting connection method is also conducive to improving the sealing of the second air guide space g. Of course, the connection method of the third extension portion 2212g and the fourth extension portion 2212h is also not limited to this, as long as the third extension portion 2212g and the fourth extension portion 2212h can be enclosed to form the second air guide space g, and this embodiment does not limit this.

[0050] Optionally, the fourth extension portion 2212h can be disposed on the third sub-membrane 2212a or on the fourth sub-membrane 2212b. It is only required that the fourth extension portion 2212h can be stacked with the third extension portion 2212g and can be jointly enclosed with the third extension portion 2212g to form the second air guide space g.

[0051] Optionally, the airbag assembly 220 may further include: a second air nozzle 224 disposed on the ventilation end 2212j. The second air nozzle 224 may be disposed on the third extension portion 2212g and / or the fourth extension portion 2212h, and the second air nozzle 224 may also be inserted into the air guide structure on the device body 100, and respectively connect the air pump and the second air guide space g. For example, the second air nozzle 224 may be inserted into the third extension portion 2212g to connect the second air guide space g, and the second air nozzle 224 may also be protruded from the side of the third extension portion 2212g away from the fourth extension portion 2212h, so that the second air nozzle 224 can be inserted into the air guide structure from the side of the device body 100 toward the wearing space 101 to connect the second air guide space g and the air pump. Similarly, the second air nozzle 224 can also be inserted into the fourth extension portion 2212h to connect to the second air guide space g, and the second air nozzle 224 can also protrude from the side of the fourth extension portion 2212h away from the third extension portion 2212g, so that the second air nozzle 224 can be inserted into the air guide structure from the side of the device body 100 away from the wearing space 101.

[0052] In addition, the second air nozzle 224 can be inserted into the air guide structure from the side of the device body 100 away from or toward the wearing space 101, and can also be inserted into the air guide structure from the side where the device body 100 is connected to the strap 211. For example, one end of the second air nozzle 224 can be wrapped by the third extension part 2212g and the fourth extension part 2212h, which is equivalent to being arranged on the third extension part 2212g and the fourth extension part 2212h, and the other end can extend outward from the second air guide space g along the length direction of the airbag body 221. In this way, when the second air nozzle 224 is assembled with the device body 100, the other end of the second air nozzle 224 can be inserted into the air guide structure from the side where the device body 100 is connected to the strap 211, so as to achieve the communication between the second air guide space g and the air pump in the device body 100. Of course, in addition to the above arrangement, the specific arrangement position of the second air nozzle 224 can also be adaptively adjusted according to the direction and position of assembly with the device body 100, which is not limited in this embodiment. Furthermore, in order to improve assembly convenience, the first air nozzle 223 and the second air nozzle 224 are preferably connected to the same side of the device body 100 .

[0053] Optionally, the fifth sub-diaphragm 2212f can also be detachably connected to the strap body 211 to achieve the detachability of the airbag body 221 and the strap body 211. The fifth sub-diaphragm 2212f can be provided with a connecting buckle 225 ( Figure 3The airbag body 221 and the strap body 211 may be provided with a buckle position (not shown) that matches the connecting buckle 225 on the side of the fifth sub-diaphragm 2212f away from the fourth sub-diaphragm 2212b, and the airbag body 221 and the strap body 211 may be detachably connected by using the matching connecting buckle 225 and buckle position. Of course, in addition to the detachable connection method of the connecting buckle 225 and the buckle position, the fifth sub-diaphragm 2212f and the strap body 211 may also be detachably connected by other methods (such as Velcro).

[0054] Optionally, the fifth sub-membrane 2212f can also be fixed to the strap body 211 by welding or sewing. Optionally, the design of the fifth sub-membrane 2212f can also be omitted, and the fourth sub-membrane 2212b can also be connected to the strap body 211 in the same or similar manner as the fifth sub-membrane 2212f.

[0055] In this embodiment, the first sub-diaphragm 2211a, the second sub-diaphragm 2211b, the third sub-diaphragm 2212a and the fourth sub-diaphragm 2212b, that is, the first diaphragm 2211 and the second diaphragm 2212 are surrounded to form a partial area of ​​the first cavity 2201 and the second cavity 2202, which can jointly constitute the first airbag. At the same time, the fourth sub-diaphragm 2212b and the fifth sub-diaphragm 2212f, that is, the partial area of ​​the second diaphragm 2212 that forms the third cavity 2203, can jointly constitute the second airbag. At the same time, when the user wears the wearable device 10, the first airbag can be set to fit the user's wrist, and the mesh sleeve 222 can play a role in isolating the first airbag and the user's wrist. The second airbag can fit the strap 211 on one side of the wearing space 101, and the first airbag is located on the side of the second airbag away from the strap 211. With such arrangement, the airbag body 221 can have a double airbag design, which is beneficial to improving the accuracy of blood pressure measurement performed by the airbag body 221 and the device body 100 .

[0056] The mesh sleeve 222 can cover the first membrane 2211 and can be stretched by the first membrane 2211 to isolate the first membrane 2211 and the user's wrist, thereby achieving a breathable and sweat-proof effect. Figure 4As shown, the mesh sleeve 222 can be covered from the side of the second sub-membrane 2211b facing away from the first sub-membrane 2211a to the side of the first sub-membrane 2211a facing away from the second sub-membrane 2211b, and the aforementioned opening 2221 is formed on the side of the first sub-membrane 2211a facing away from the second sub-membrane 2211b, so that the mesh sleeve 222 can not only use the opening 2221 to avoid the conductive part 2213, but also can use the opening 2221 to be set on the first membrane 2211, or be detached from the first membrane 2211. The mesh 222 may be a woven material (such as a webbing) to improve the air permeability of the mesh 222, and the woven material of the mesh 222 may also have a certain elastic deformation ability, so that the mesh 222 can be deformed under the action of an external force to expand the opening 2221 to be detached from the first diaphragm 2211, thereby realizing a detachable connection between the mesh 222 and the airbag body 221. Similarly, the mesh 222 may also be sleeved on the first diaphragm 2211 by expanding the opening 2221. In addition, the deformability of the mesh 222 may also reduce the restraint caused by the mesh 222 on the expansion of the first diaphragm 2211, so that the mesh 222 can be deformed accordingly with the expansion of the first diaphragm 2211, so as to reduce the probability that the mesh 222 affects the compression efficiency of the filled airbag.

[0057] See also Figures 8 to 9 , Figure 8 yes Figure 3 Another schematic diagram of the connection structure between the first diaphragm 2211 and the mesh sleeve 222, Fig. 9 yes Figure 3 FIG. 2 is another schematic diagram of a connection structure between the first diaphragm 2211 and the mesh sleeve 222.

[0058] Optionally, the airbag body 221 may also be connected to the device body 100 not only through the second diaphragm 2212, so as to achieve the expansion or contraction of the first airbag. That is, in addition to being connected to the second diaphragm 2212 (the second cavity 2202), the device body 100 may also be connected to the first diaphragm 2211 (the first cavity 2201), so as to use the first diaphragm 2211 to inflate the first airbag (the first cavity 2201 and the second cavity 2202). Figures 8 to 9As shown, the first diaphragm 2211 can be generally arranged like the second diaphragm 2212, that is, it can be provided with a structure that is the same as or similar to the gas-conducting end 2212e. For example, the first sub-diaphragm 2211a can be provided with a first extension 2212c, the second sub-diaphragm 2211b can be provided with a second extension 2212d, and the first extension 2212c and the second extension 2212d can be stacked and arranged to form the gas-conducting end 2212e. In this arrangement, the first diaphragm 2211 can also be connected to the air pump in the device body 100 by using the gas-conducting end 2212e, so that the device body 100 can inflate the first cavity 2201 and the second cavity 2202 to achieve the expansion of the first airbag.

[0059] Furthermore, the mesh sleeve 222 sleeved on the first diaphragm 2211 may be provided with a notch 2222 (eg, Figure 8 As shown in the figure), the air guide end 2212e is avoided. For example, the air guide end 2212e can be inserted through the notch 2222 in the mesh sleeve 222 to extend outside the mesh sleeve 222 and connect with the device body 100. At this time, if the mesh sleeve 222 is to be removed, the air guide end 2212e needs to be removed from the device body 100 first. For another example, the notch 2222 in the mesh sleeve 222 for the air guide end 2212e to pass through can be connected to the opening 2221 (as shown in the figure). Fig. 9 As shown), when the mesh sleeve 222 is disassembled, the air guide end 2212e can enter the opening 2221 along the notch 2222 and detach from the mesh sleeve 222 from the opening 2221 together with the first diaphragm 2211, without the need to detach the air guide end 2212e from the device body 100, which is beneficial to improving the convenience of disassembly of the mesh sleeve 222.

[0060] The airbag assembly 220 provided in the present application is configured to connect a first diaphragm 2211 and a second diaphragm 2212, and to form a conductive portion 2213 connecting the first diaphragm 2211 and the second diaphragm 2212, and the second diaphragm 2212 is also connected to the device body 100, and the first diaphragm 2211 and the second diaphragm 2212 can also expand or contract under the control of the device body 100, so that the overall expansion stroke of the airbag body 221 can be increased to increase the pressure exerted by the airbag body 221 on the user's wrist, which is beneficial to improving the accuracy of blood pressure measurement performed by the device body 100 through the airbag body 221. At the same time, by providing a mesh sleeve 222 with an opening 2221, the opening 2221 can be used to be sleeved on the first diaphragm 2211, and the opening 2221 can also avoid the conductive part 2213, so that the mesh sleeve 222 can not only isolate the user's wrist and the first diaphragm 2211, but also can be directly detached from the first diaphragm 2211 when the second diaphragm 2212 is in a connected state with the device body 100, without being restricted by the connection between the airbag body 221 and the device body 100, which is beneficial to improving the convenience of users to remove the mesh sleeve 222.
