[0033] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0034] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0035] Please see Figures 1 to 2 , Figure 1 This is a schematic diagram of the structure of the wearable device 10 provided in the embodiments of this application. Figure 2 yes Figure 1 A schematic diagram of the connection structure between the middle strap assembly 100 and the device body 200.

[0036] The wearable device 10 provided in this application can be a smartwatch, a smart bracelet, or a cuff-type blood pressure measuring device, etc. The following example uses a smartwatch as the wearable device 10. Figures 1 to 2 As shown, the wearable device 10 may include a strap assembly 100 and a device body 200. The strap assembly 100 can be connected to the device body 200 and together they form a wearing space 101, through which the user can wear the wearable device 10 on their wrist. Simultaneously, the strap assembly 100 can expand under the control of the device body 200 to compress the blood vessels in the user's wrist for blood pressure measurement. Furthermore, the strap assembly 100 can be detachably connected to the device body 200, allowing both the strap assembly 100 and the device body 200 to be removed separately for repair or replacement. In particular, since the strap assembly 100 is generally only compatible with one person, when another person uses the strap assembly 100 to measure blood pressure, the measurement results may be significantly inaccurate or impossible to measure. Based on this, by making the strap component 100 detachable, users can replace different strap components 100 with the device body 200 to measure the blood pressure of others, rather than being limited to their own use, which helps to expand the scope of application of the wearable device 10.

[0037] The term "smartwatch" as used herein refers to a device with information processing capabilities that meets the basic technical requirements of a watch. In addition to telling time, a smartwatch should also have one or more functions such as reminders, navigation, calibration, monitoring, and interaction. For example, wearable devices can utilize the Bluetooth data transmission standard to enable collaborative interaction. They can also incorporate various monitoring sensors, such as those for monitoring ambient light, geomagnetism, temperature, barometric pressure, altitude, gyroscopes, accelerometers, and heart rate. Furthermore, the display methods of a smartwatch can include, but are not limited to, analog, numerical, and graphical representations.

[0038] The strap assembly 100 can be worn on a user's wrist, and the device body 200 can inflate the strap assembly 100 to expand and compress blood vessels in the user's wrist, thereby measuring the pressure exerted by the strap assembly 100 on the user and the user's pulse pressure wave. Figures 1 to 2As shown, the strap assembly 100 may include a strap 110, an airbag structure 120, and a connecting structure 130. The strap 110 can be connected to the device body 200, and the strap 110 and the device body 200 together form the aforementioned wearing space 101. The airbag structure 120 can be connected to the strap 110 and is located on the side of the strap 110 facing the wearing space 101. Simultaneously, the airbag structure 120 can also be detachably connected to the device body 200, and the device body 200 can inflate the airbag structure 120 to inflate and compress the user's blood vessels. The connecting structure 130 can be detachably connected to the device body 200, and the airbag structure 120 can be mounted on the connecting structure 130 to achieve a detachable connection between the airbag structure 120 and the device body 200. In this embodiment, the airbag structure 120 can be detached from the device body 200 along the length direction L via the connecting structure 130, so that the airbag structure 120 can be removed and replaced separately, so that the user can replace the appropriate airbag structure 120 to measure the blood pressure of others.

[0039] It is understood that the airbag structure 120 can be a strip-shaped structure similar to the strap 110, and the aforementioned length direction L refers to the length direction of the airbag structure 120 in the flattened state after it is connected to the device body 200.

[0040] The strap 110 can specifically be a watch strap, and the strap 110 can be connected to opposite sides of the device body 200 to form a wearing space 101 together with the device body 200. Figure 1 As shown, one end of the strap 110 can be connected to one side of the device body 200, and the other end can pass through the connecting ring on the opposite side of the device body 200, and be folded onto the side of the strap 110 away from the wearing space 101, and secured by structural components such as metal buckles or Velcro. Simultaneously, one end of the strap 110 can also be detachably connected to one side of the device body 200 to facilitate replacement of the strap 110 or the device body 200. For example, one end of the strap 110 can be detachably connected to one side of the device body 200 via spring bars. Furthermore, the strap 110 can be made of flexible, skin-friendly materials such as silicone, rubber, soft plastic, or braided straps to improve user comfort. Of course, the strap 110 can also be made of metal to create a metal watchband to enhance the overall texture of the strap 110.

[0041] Optionally, in addition to using spring bar pins for detachable connection, the strap 110 and the device body 200 can also employ a detachable structure that can be unlocked by pressing, flicking, or pulling to achieve a detachable connection between the two. The specific detachable structure of the strap 110 and the device body 200 can be found in existing technology, and will not be described in detail here. Optionally, one end of the strap 110 can also be fixedly connected to one side of the device body 200, making the two non-detachable.

[0042] Optionally, in addition to using a single, longer strap 110 to form the wearing space 101 together with the device body 200, two shorter straps 110 can also be used to form the wearing space 101 together with the device body 200. One end of each strap 110 can be connected to opposite sides of the device body 200, and the other ends can be connected via structural components such as metal buckles or Velcro, allowing the device body 200 and the two straps 110 to form the wearing space 101 together. Simultaneously, the airbag structure 120 can be connected to either of the two straps 110, or both straps 110 can have an airbag structure 120. The airbag structure 120 only needs to be located on the side of the strap 110 facing the wearing space 101 and detachably connected to the device body 200; this embodiment does not impose any limitations on this.

[0043] Optionally, the strap 110 can be integrated with the airbag structure 120, meaning the strap 110 can be part of the airbag structure 120. Alternatively, the strap 110 can be omitted, allowing the strap assembly 100 to consist only of the airbag structure 120 and the connecting structure 130. In this case, the airbag structure 120 can replace the strap 110 and together with the device body 200 to form the wearing space 101. The user only needs to be able to wear the device body 200 on their wrist through the airbag structure 120, and the airbag structure 120 needs to inflate and compress the blood vessels in the user's wrist.

[0044] All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. 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 may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0045] Please see Figures 3 to 5 , Figure 3 yes Figure 2 A schematic diagram of the cross-sectional structure of the central airbag structure 120, the connecting structure 130, and the equipment body 200 along section V-V. Figure 4 These are assembly diagrams of the airbag structure 120 and the device body 200 in some designs. Figure 5 These are assembly diagrams of the airbag structure 120 and the equipment body 200 in some schemes.

[0046] The airbag structure 120 can be connected to the side of the strap 110 facing the wearing space 101, and the airbag structure 120 can also be mounted on the device body 200 via the connecting structure 130, and can inflate under the control of the device body 200 to compress the blood vessels in the user's wrist. Figure 3 As shown, the airbag structure 120 may include an air nozzle 121 and an airbag body 122. The air nozzle 121 can be connected to the airbag body 122 along the length direction L, and can also be mounted on a connecting structure 130, and can be mounted to the device body 200 via the connecting structure 130. The airbag body 122 can be connected to the strap 110 and is located on the side of the strap 110 facing the wearing space 101. The device body 200 can inflate the airbag body 122 through the air nozzle 121, causing the airbag body 122 to expand and compress the blood vessels in the user's wrist. Since the air nozzle 121 is connected to the airbag body 122 along the length direction L, the air nozzle 121 can be detached from the device body 200 along the length direction L via the connecting structure 130. This configuration allows for a detachable connection between the airbag structure 120 and the device body 200 along the length direction L, facilitating the user to replace the airbag structure 120 with a suitable one to measure the blood pressure of others.

[0047] It is understood that the airbag body 122 can be a strip-shaped structure similar to the strap 110, and the length direction L can specifically be the length direction of the airbag body 122 in the flattened state, while the air nozzle 121 can be connected to one end of the airbag body 122 in the length direction L.

[0048] Through long-term research, the inventors discovered that in most designs, the air nozzle 121 is connected to the airbag body 122 along its thickness direction, making the extension direction of the air nozzle 121 perpendicular to the length direction L of the airbag body 122. This perpendicular connection structure means that the airbag structure 120 can only be assembled with the device body 200 in two ways. The first way is that the air nozzle 121 is assembled onto the side surface 210 of the device body 200 along its extension direction, while the length direction L of the airbag body 122 is parallel to the side surface 210. This means that the other end of the airbag body 122 can only be extended from one side of the bottom surface 220 of the device body 200 (e.g., ...). Figure 4(As shown). With this assembly method, after the user wears the wearable device 10, the user's wrist size is larger than the size of the device body 200, which can cause a large-angle bend in a part of the airbag body 122 extending from the bottom surface 220. This reduces the gap between the cavity walls of the bend area of ​​the airbag body 122, which is not conducive to the device body 200 inflating the airbag body 122.

[0049] The second method involves mounting the air nozzle 121 onto the bottom surface 220 of the device body 200 along its extension direction, while the length direction L of the airbag body 122 is perpendicular to the side surface 210, allowing the other end of the airbag body 122 to extend out from the side surface 210 of the device body 200 (e.g., Figure 5 (As shown). Although this assembly method can avoid large-angle bending of the airbag body 122, the length of the air nozzle 121 in its extension direction and the thickness of the airbag body 122 will increase the thickness of the device body 200, which is not conducive to making the device body 200 thinner. That is, the device body 200 needs to be designed to be thick enough to accommodate the air nozzle 121 and the airbag body 122 in the thickness direction Z (perpendicular to the length direction L), so as to ensure that the airbag structure 120 can be assembled onto the device body 200 from the bottom surface 220 side.

[0050] Based on this, the airbag structure 120 provided in this application embodiment connects the air nozzle 121 to the airbag body 122 in the length direction L, so that the extension direction of the air nozzle 121 can be parallel to the length direction L of the airbag body 122. When the air nozzle 121 is assembled to the side 210 of the device body 200 in the length direction L through the connecting structure 130 (e.g. Figure 2 and Figure 3 As shown, the length direction L of the airbag body 122 can be perpendicular to the side surface 210. This arrangement not only avoids the problem of large-angle bending of the airbag body 122, but also changes the stacking of the air nozzle 121 and the airbag body 122 in the thickness direction Z to a stacking in the length direction L, thereby reducing the impact of the air nozzle 121 and the airbag body 122 on the thickness of the device body 200, which is beneficial for making the device body 200 thinner. The specific structure of the air nozzle 121 will be described in detail below.

[0051] Please combine Figure 3 See Figures 6 to 9 , Figure 6 yes Figure 2 A schematic diagram of the central airbag structure 120. Figure 7 yes Figure 6 A schematic diagram of the structure of the middle air nozzle 121. Figure 8 yes Figure 7 Another structural schematic diagram of the middle fixing part 1211, Figure 9 yes Figure 7 Another structural schematic diagram of the central air nozzle 121.

[0052] The air nozzle 121 can be connected to the airbag body 122 and the device body 200 along the length direction L, and the device body 200 can inflate the airbag body 122 through the air nozzle 121. Figure 3 and Figure 6 As shown, the air nozzle 121 may include a fixing part 1211 and a guiding part 1212. The fixing part 1211 can be embedded in the airbag body 122 along its length L, and together with the airbag body 122, it can form an inflation cavity 1201. The fixing part 1211 can also be mounted on the connecting structure 130. The guiding part 1212 can be connected to the side of the fixing part 1211 opposite to the cavity 1201, and the guiding part 1212 can connect the device body 200 and the cavity 1201, allowing the device body 200 to inflate the cavity 1201. In this embodiment, the air nozzle 121 can be made of high-hardness TPU, and the fixing part 1211 and the guiding part 1212 can be an integral structure, manufactured together using corresponding processes.

[0053] The fixing part 1211 can be plate-shaped and can be embedded in the end of the airbag body 122 along the length direction L. Both sides of the fixing part 1211 along the thickness direction Z can be connected to the airbag body 122, allowing the airbag body 122 to hold the fixing part 1211 in the middle, thus forming a cavity 1201 together. The fixing part 1211 and the airbag body 122 can be joined using high-frequency hot pressing, allowing the airbag body 122 to be heat-fused to the opposite sides of the fixing part 1211, improving the airtightness of the cavity 1201 formed by the fixing part 1211 and the airbag body 122. Simultaneously, the fixing part 1211 can also have a first air guide hole 1202 connecting the cavity 1201 and the outside of the airbag body 122, allowing the device body 200 to inflate the cavity 1201 through the first air guide hole 1202. For example, the side of the fixing part 1211 facing away from the cavity 1201 can be exposed outside the airbag body 122, and can be flush with the airbag body 122 in the length direction L. The first air guide hole 1202 can penetrate the side of the fixing part 1211 located inside the cavity 1201 and the side of the fixing part 1211 facing away from the cavity 1201, so as to connect the cavity 1201 and the outside of the airbag body 122.

[0054] The fixing part 1211 and the airbag body 122 are respectively provided on the opposite sides of their connection. For example, Figure 6 and Figure 7As shown, the first convex bulge 12111 and the second convex bulge 12112 can be arranged opposite each other in the thickness direction Z. The first air guide hole 1202 can be located between the first convex bulge 12111 and the second convex bulge 12112, and the first air guide hole 1202 can penetrate the fixing part 1211 in the thickness direction Z to connect the first convex bulge 12111 and the second convex bulge 12112. With this arrangement, the thickness of the fixing part 1211 can be locally increased by utilizing the first convex bulge 12111 and the second convex bulge 12112 to open the first air guide hole 1202 with a larger diameter, which is beneficial to improving the efficiency of the device body 200 in filling the cavity 1201 with air through the first air guide hole 1202. Optionally, when the maximum opening diameter of the first air guide hole 1202 is smaller than the thickness of the fixing part 1211, the design of the first convex bulge 12111 and the second convex bulge 12112 can also be omitted.

[0055] The terms "first," "second," and "third" used in this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature.

[0056] To improve the pressure effect of the airbag body 122 on the user's wrist, the airbag structure 120 can have two airbag bodies 122 to achieve a dual-airbag solution, and the fixing part 1211 can be connected to both airbag bodies 122 simultaneously. Figure 6 and Figure 7 As shown, the fixing part 1211 may include a first fixing part 1211a and a second fixing part 1211b. The first fixing part 1211a can be embedded in one airbag body 122 along the length direction L, and together with the airbag body 122, form a cavity 1201. The second fixing part 1211b can be embedded in another airbag body 122 along the length direction L, and together with the airbag body 122, form another cavity 1201, thereby realizing the dual-airbag scheme of the airbag structure 120.

[0057] Meanwhile, both the first fixing part 1211a and the second fixing part 1211b can be provided with a first air guide hole 1202. The device body 200 can inflate the two cavities 1201 through the two first air guide holes 1202 respectively, so as to realize the expansion of the two airbag bodies 122. In this embodiment, the first fixing part 1211a and the second fixing part 1211b are connected to form an integral structure, and can be symmetrically arranged about the length direction L. The specific arrangement of the two can be referred to the fixing part 1211 in the previous embodiment, and will not be repeated here.

[0058] Optionally, in addition to being connected to form an integral structure, the first fixing part 1211a and the second fixing part 1211b can also be two independent structural components. As long as they can be connected to the two airbag bodies 122 respectively and can be assembled on the connecting structure 130, this embodiment does not limit this.

[0059] Optionally, the first fixing part 1211a and the second fixing part 1211b may also share the same first air guide hole 1202. For example... Figure 8 As shown, the first air guide hole 1202 can have three openings: one opening connects to the cavity 1201 enclosed by the first fixing part 1211a, one opening connects to the cavity 1201 enclosed by the second fixing part 1211b, and the other opening connects to the side of either the first fixing part 1211a or the second fixing part 1211b that is exposed outside the airbag body 122 in the length direction L. With this configuration, the device body 200 can simultaneously inflate two cavities 1201 through one first air guide hole 1202, causing the two airbag bodies 122 to expand. In this embodiment, to achieve independent inflation of the two airbag bodies 122, an air valve can be provided inside the first air guide hole 1202 to control the air intake of the two airbag bodies 122.

[0060] It is understandable that when the airbag structure 120 is a single airbag design, the fixing part 1211 may only include a first fixing part 1211a or a second fixing part 1211b to connect to one airbag body 122. In this case, the "fixing part" can also be called the "first fixing part" or the "second fixing part," and vice versa. That is to say, there can be only one fixing part in a single airbag design.

[0061] like Figures 6 to 7As shown, the fixing part 1211 may also have a positioning hole 1203, which can position the fixing part 1211 when it is hot-pressed with the airbag body 122 to prevent it from shifting during hot pressing. For example, the fixing part 1211 can be placed inside the hot pressing mold, and the positioning structure of the hot pressing mold can be accommodated through the positioning hole 1203 to achieve positioning assembly of the fixing part 1211 and the hot pressing mold. At the same time, the positioning hole 1203 can also be used to achieve positioning assembly of the fixing part 1211 and the connecting structure 130 to improve the assembly convenience of the fixing part 1211 and the connecting structure 130. In this embodiment, when the airbag structure 120 is a dual-airbag scheme, the positioning hole 1203 can be opened in the area where the first fixing part 1211a and the second fixing part 1211b meet, that is, in the area where the first fixing part 1211a and the second fixing part 1211b are not covered by the airbag body 122, so as to avoid the positioning hole 1203 affecting the thermal pressure connection between the first fixing part 1211a and the second fixing part 1211b and the airbag body 122.

[0062] Optionally, the positioning hole 1203 may be used solely for thermally pressing the fixing part 1211 and the airbag body 122. Alternatively, the positioning hole 1203 may be used solely for positioning and assembling the fixing part 1211 and the connecting structure 130; this embodiment does not limit this. Optionally, the design of the positioning hole 1203 may also be omitted.

[0063] Optionally, the positioning hole 1203 can also be formed on at least one of the first fixing part 1211a and the second fixing part 1211b, and is not limited to being formed on the part where the first fixing part 1211a and the second fixing part 1211b meet. Taking the first fixing part 1211a as an example, in order to avoid the positioning hole 1203 affecting the thermo-pressed connection between the first fixing part 1211a and the airbag body 122, a part of the first fixing part 1211a can be provided to protrude from the airbag body 122, and the positioning hole 1203 is preferably formed on the part of the first fixing part 1211a that protrudes from the airbag body 122. Of course, the positioning hole 1203 can also be formed on the area of ​​the first fixing part 1211a that is covered by the airbag body 122, as long as the airbag body 122 is designed to avoid the positioning hole 1203, such as by making an opening, so that the positioning structure of the thermo-pressed mold and the connecting structure 130 can be positioned and assembled with the positioning hole 1203. Optionally, the number of positioning holes 1203 is not limited to one. Multiple positioning holes 1203 may be provided, such as two, three, four or more. This embodiment does not limit this.

[0064] like Figure 3 and Figure 6As shown, the connecting part 1212 can be connected to the side of the fixing part 1211 opposite to the cavity 1201, that is, the side of the fixing part 1211 exposed outside the airbag body 122 in the length direction L, and the extension direction of the connecting part 1212 can be parallel to the length direction L. When the air nozzle 121 is assembled onto the device body 200 through the connecting structure 130, the connecting part 1212 can be inserted into the device body 200 in the length direction L, and connect the device body 200 and the cavity 1201, so that the device body 200 can inflate the cavity 1201. The connecting part 1212 can be cylindrical in shape, and the connecting part 1212 can have a connecting first air vent 1202 and a second air vent 1204 on the side of the connecting part 1212 opposite to the fixing part 1211. When the conductive part 1212 is inserted into the device body 200, the second air vent 1204 can connect the device body 200 and the first air vent 1202, allowing the device body 200 to be inflated into the cavity 1201 through the first air vent 1202 and the second air vent 1204. Furthermore, when the fixing part 1211 is assembled onto the connecting structure 130, the conductive part 1212 can also protrude from the connecting structure 130, allowing the conductive part 1212 to be inserted into the device body 200 through the portion protruding from the connecting structure 130, thus connecting the device body 200 and the cavity 1201.

[0065] Optionally, the design of the connecting part 1212 can be omitted. For example, when the fixing part 1211 is assembled onto the device body 200 via the connecting structure 130, the device body 200 can be provided with a corresponding air outlet structure, which can be inserted into the first air guide hole 1202 of the fixing part 1211, allowing the device body 200 to inflate the cavity 1201 through the first air guide hole 1202. The connecting structure 130 can also be designed with a clearance hole communicating with the fixing part 1211, allowing the air outlet structure of the device body 200 to be inserted into the first air guide hole 1202 through the clearance hole. Optionally, when the design of the connecting part 1212 is retained, the device body 200 can also be provided with an air outlet structure, which can be inserted into the second air guide hole 1204 of the connecting part 1212 to achieve communication between the device body 200 and the cavity 1201.

[0066] To improve the airtightness of the connection between the conductive part 1212 and the device body 200, a sealing ring 1213 may also be provided on the peripheral side of the conductive part 1212 opposite to the second air guide hole 1204. For example... Figure 3 and Figure 6As shown, the sealing ring 1213 can be located at the end of the conductive portion 1212 away from the fixing portion 1211. When the conductive portion 1212 is inserted into the device body 200, the sealing ring 1213 can interfere with the device body 200, allowing the sealing ring 1213 to abut against both the conductive portion 1212 and the device body 200, thereby improving the airtightness of the connection between the conductive portion 1212 and the device body 200. In this embodiment, the sealing ring 1213 and the conductive portion 1212 can be an integral structure to improve the connection strength between the sealing ring 1213 and the conductive portion 1212.

[0067] Optionally, when the design of the conductive part 1212 is omitted and the device body 200 is provided with an air outlet structure, the sealing ring 1213 can also be provided on the air outlet structure. After the first air guide hole 1202 is inserted into the air outlet structure, it can interfere with the inner wall of the first air guide hole 1202 to improve air tightness. Similarly, when the design of the conductive part 1212 is retained and the device body 200 is provided with an air outlet structure, the sealing ring 1213 can also be provided on the air outlet structure. After the second air guide hole 1204 is inserted into the air outlet structure, it can interfere with the inner wall of the second air guide hole 1204 to improve air tightness.

[0068] Alternatively, the sealing ring 1213 may not be limited to the end of the conductive portion 1212 away from the fixing portion 1211, and the sealing ring 1213 may be a structural component independent of the conductive portion 1212. The sealing ring 1213 may be made of elastic materials such as rubber, silicone and soft plastic, and may be fixedly connected to the conductive portion 1212 by means of bonding, welding or embedding.

[0069] When the airbag structure 120 adopts the above-described dual-airbag design, the guiding portion 1212 may include: a first guiding portion 1212a and a second guiding portion 1212b. For example... Figure 6 and Figure 7As shown, the first guiding part 1212a can be connected to the side of the first fixing part 1211a exposed outside the airbag body 122 in the length direction L, and the second guiding part 1212b can be connected to the side of the second fixing part 1211b exposed outside the airbag body 122 in the length direction L. Both the first guiding part 1212a and the second guiding part 1212b are provided with a second air guide hole 1204. When the air nozzle 121 is assembled onto the device body 200 through the connecting structure 130, the first guiding part 1212a and the second guiding part 1212b can be inserted into the device body 200 in the length direction L, and the device body 200 can inflate the cavities 1201 of the two airbag bodies 122 through the first guiding part 1212a and the second guiding part 1212b respectively, so as to realize the expansion of the two airbag bodies 122. Furthermore, both the first conductive part 1212a and the second conductive part 1212b may be provided with a sealing ring 1213 to improve the airtightness of the connection between them and the device body 200. In this embodiment, the first conductive part 1212a and the second conductive part 1212b may be symmetrically arranged about the length direction L, and the specific arrangement of the two can be referred to the conductive part 1212 in the previous embodiment, which will not be repeated here.

[0070] It is understandable that when the airbag structure 120 is a single airbag design, the connecting part 1212 may only include a first connecting part 1212a or a second connecting part 1212b to connect the device body 200 with the cavity 1201 of the single airbag body 122. In this case, the "connecting part" can also be called the "first connecting part" or the "second connecting part," and vice versa. That is to say, there can be only one connecting part in a single airbag design.

[0071] Optionally, when the airbag structure 120 is a dual-airbag design, the guiding portion 1212 may only include: a first guiding portion 1212a or a second guiding portion 1212b. That is, the two airbag bodies 122 can share a single guiding portion 1212 for inflation. Figure 9 As shown, taking the two airbag bodies 122 sharing a first conductive part 1212a as an example, the first conductive part 1212a can be connected to the portion of the first fixing part 1211a and the second fixing part 1211b that are connected, and is located in the length direction L. At the same time, the first fixing part 1211a and the second fixing part 1211b can share a first air guide hole 1202 as in the previous embodiment, and the second air guide hole 1204 on the first conductive part 1212a can communicate with the first air guide hole 1202 shared by the first fixing part 1211a and the second fixing part 1211b, so that the device body 200 can simultaneously inflate the cavity 1201 of the two airbag bodies 122 through the first conductive part 1212a.

[0072] Because the airbag body 122 and the fixing part 1211 are connected by high-frequency hot pressing, the fixing part 1211 and the airbag body 122 will melt and form overflowing TPU adhesive during the hot pressing connection. In particular, when the TPU adhesive overflows to the side of the fixing part 1211 that connects to the conductive part 1212 and cures, the TPU adhesive is prone to interfering with the device body 200 when the conductive part 1212 is inserted into the device body 200, resulting in the conductive part 1212 not being properly assembled.

[0073] To prevent TPU adhesive from overflowing onto the side where the fixing part 1211 connects to the conducting part 1212, the air nozzle 121 may further include: a protrusion 1214 and a baffle 1215 disposed on the protrusion 1214. For example... Figure 3 and Figure 6 As shown, the protrusion 1214 can be connected to the side of the fixing part 1211 opposite to the cavity 1201, that is, to the side of the fixing part 1211 exposed outside the airbag body 122 in the length direction L. The protrusion 1214 can also protrude from the side surface of the airbag body 122 in the length direction L. The guiding part 1212 can be connected to the side of the protrusion 1214 opposite to the fixing part 1211, and the first air duct 1202 can penetrate the protrusion 1214 in the length direction L to connect with the second air duct 1204. Simultaneously, the protrusion 1214 has baffles 1215 on both opposite sides in the thickness direction Z. The baffles 1215 can be arranged adjacent to the airbag body 122 and can be located between the guiding part 1212 and the airbag body 122. The orthographic projection of the portion of the airbag body 122 connected to the fixing part 1211 in the length direction L can also be located on the baffles 1215. With this configuration, when the TPU adhesive overflows along the length L of the fixing part 1211 towards the side away from the cavity 1201, the baffle 1215 can prevent the TPU adhesive from overflowing, thus avoiding it from overflowing to the side where the protrusion 1214 connects to the conductive part 1212. Furthermore, the baffle 1215 can also partially shield the area where the fixing part 1211 and the airbag body 122 are heat-pressed together, serving a decorative purpose.

[0074] Alternatively, the design of the protrusion 1214 and the retaining wall 1215 can be omitted. Or, the protrusion 1214 and the retaining wall 1215 can also be part of the fixing part 1211.

[0075] When the airbag structure 120 is a dual-airbag design, the protrusion 1214 and the baffle 1215 can be configured as two sets. For example... Figure 7As shown, the protrusion 1214 may include a first protrusion 1214a and a second protrusion 1214b, and the baffle 1215 may include a first baffle 1215a and a second baffle 1215b. The first protrusion 1214a may be disposed between the first fixing portion 1211a and the first conducting portion 1212a, and the first baffle 1215a may be located on opposite sides of the first protrusion 1214a in the thickness direction Z. The second protrusion 1214b may be disposed between the second fixing portion 1211b and the second conducting portion 1212b, and the second baffle 1215b may be located on opposite sides of the second protrusion 1214b in the thickness direction Z. In this embodiment, the first protrusion 1214a and the second protrusion 1214b can be symmetrically arranged about the length direction L, and the first retaining wall 1215a and the second retaining wall 1215b can also be symmetrically arranged about the length direction L. The specific arrangement of the four can be referred to the protrusion 1214 and the retaining wall 1215 in the previous embodiment, and will not be described in detail here.

[0076] Understandably, when the airbag structure 120 is a single airbag design, the protrusion 1214 may only include the first protrusion 1214 or the second conductive part 1212b, and the baffle 1215 may only include the first baffle 1215a and the second baffle 1215b, to block the overflow of TPU adhesive generated by the single airbag body 122. In this case, the "protrusion" can also be called the "first protrusion" or the "second protrusion," and the "first protrusion" can also be called the "second protrusion," and the "second protrusion" can also be called the "first protrusion." The same applies to the "baffle," the "first baffle," and the "second baffle."

[0077] The airbag body 122 can be made of a highly flexible TPU material, and the airbag body 122 can inflate under the control of the device body 200 to compress the blood vessels in the user's wrist. Figure 3 and Figure 6As shown, the airbag body 122 may include a first membrane layer 1221 and a second membrane layer 1222. The first membrane layer 1221 and the second membrane layer 1222 may be stacked together and connected by high-frequency heat sealing. A fixing part 1211 may be embedded in the length direction L between the first membrane layer 1221 and the second membrane layer 1222, forming a cavity 1201 together with the first membrane layer 1221 and the second membrane layer 1222. The fixing part 1211 may be located at the ends of the first membrane layer 1221 and the second membrane layer 1222 in the length direction L. Simultaneously, the first membrane layer 1221 and the second membrane layer 1222 may also be connected to opposite sides of the fixing part 1211 by high-frequency heat sealing. The fixing part 1211 has the aforementioned first protrusion 12111 on the side near the first membrane layer 1221, and the fixing part 1211 has the aforementioned second protrusion 12112 on the side near the second membrane layer 1222. Furthermore, the side surface of the fixing part 1211 may be exposed outside the airbag body 122 to facilitate the fixing part 1211's engagement with external structures. In this embodiment, the thickness of the airbag body 122 can specifically be 0.15-0.2 mm.

[0078] Optionally, in addition to clamping the fixing part 1211 in the middle, the first membrane layer 1221 and the second membrane layer 1222 can also jointly wrap around the fixing part 1211. That is, in addition to being connected to the opposite sides of the fixing part 1211, the first membrane layer 1221 and the second membrane layer 1222 can also be connected to the side surface of the fixing part 1211 to improve the connection strength between the fixing part 1211 and the airbag body 122. Of course, the connection method between the first membrane layer 1221 and the second membrane layer 1222 and the fixing part 1211 is not limited to this. As long as the three can be jointly arranged to form a cavity 1201, and the fixing part 1211 is located at the end of the first membrane layer 1221 and the second membrane layer 1222 in the length direction L, this embodiment does not limit this.

[0079] When the airbag structure 120 is a dual-airbag design, the number of airbag bodies 122 can be two. For example... Figure 6 and Figure 7 As shown, the airbag body 122 may include a first airbag body 122a and a second airbag body 122b. The first airbag body 122a can be connected to the first fixing part 1211a, and together with the first fixing part 1211a, they enclose a cavity 1201. The second airbag body 122b can be connected to the second fixing part 1211b, and together with the second fixing part 1211b, they enclose a cavity 1201. In this embodiment, the first airbag body 122a and the second airbag body 122b may also be symmetrically arranged about the length direction L, and their specific arrangement can be referred to the airbag body 122 in the previous embodiment, which will not be repeated here.

[0080] It is understandable that when the airbag structure 120 is a single airbag design, the airbag body 122 may only include the first airbag body 122a or the second airbag body 122b, which together with the fixing part 1211 form a cavity 1201. In this case, the "airbag body" can also be referred to as the "first airbag body" or the "second airbag body", and the "first airbag body" can also be referred to as the "second airbag body", and the "second airbag body" can also be referred to as the "first airbag body".

[0081] The airbag structure 120 provided in this embodiment of the application has a fixing part 1211 embedded in the length direction L between the first membrane layer 1221 and the second membrane layer 1222, and located at the ends of the first membrane layer 1221 and the second membrane layer 1222, so that the air nozzle 121 can be connected to the airbag body 122 in the length direction L. This arrangement not only avoids the problem of large-angle bending of the airbag body 122 in the aforementioned embodiments, but also changes the stacking of the air nozzle 121 and the airbag body 122 in the thickness direction Z to stacking in the length direction L, thereby reducing the impact of the air nozzle 121 and the airbag body 122 on the thickness of the device body 200, which is beneficial for making the device body 200 thinner.

[0082] Please combine Figure 3 See Figures 10 to 14 , Figure 10 yes Figure 2 A schematic diagram of the connection structure between the central airbag structure 120 and the connecting structure 130. Figure 11 yes Figure 10 A schematic diagram of the connection structure between the central airbag structure 120 and the partial connecting structure 130. Figure 12 yes Figure 10 A schematic diagram of the structure of the mounting base 131. Figure 13 yes Figure 10 Another structural diagram of the mounting base 131, Figure 14 yes Figure 10 A schematic diagram of the cross-sectional structure of the central airbag structure 120 and the connecting structure 130 along VI-VI.

[0083] The connection structure 130 can be used to install the air nozzle 121, and can achieve a detachable connection between the air nozzle 121 and the equipment body 200. For example... Figure 3 and Figures 10 to 11As shown, the connection structure 130 may include: a mounting base 131, a cover plate 132, and a resilient snap-fit ​​member 133. The mounting base 131 is used to mount the air nozzle 121, and the air nozzle 121 can be mounted onto the device body 200 along its length direction L via the mounting base 131. The cover plate 132 can be placed on the mounting base 131 and can be used to fix the air nozzle 121. The resilient snap-fit ​​member 133 can be disposed on the mounting base 131 and protrude from the cover plate 132 in the thickness direction Z, and the resilient snap-fit ​​member 133 can realize a detachable connection between the mounting base 131 and the device body 200. In this embodiment, the connection structure 130 also has the advantage of convenient assembly and disassembly, which is beneficial to improving the ease of assembly and disassembly of the connection structure 130 and the device body 200.

[0084] The mounting base 131 may be provided with a mounting groove 1301 for assembling the air nozzle 121, and can drive the air nozzle 121 to be assembled onto the equipment body 200 along the length direction L. For example... Figures 11 to 12 As shown, the mounting base 131 may have a first surface 1311 parallel to the length direction L and perpendicular to the thickness direction Z, and a second surface 1312 perpendicular to the first surface 1311. The mounting base 131 has a mounting groove 1301 on the first surface 1311, and the fixing part 1211 can be fitted into the mounting groove 1301 from a direction perpendicular to the first surface 1311 (i.e., the thickness direction Z). Simultaneously, the mounting groove 1301 may also penetrate the second surface 1312, forming an opening on the second surface 1312 to avoid obstructing the airbag body 122 connected to the fixing part 1211, allowing the airbag body 122 to extend out of the mounting groove 1301 through the opening in the second surface 1312. In this embodiment, the first surface 1311 and the second surface 1312 may be connected. Alternatively, they may be perpendicular but not connected. In addition, the depth of the mounting groove 1301 can be greater than or equal to the thickness of the air nozzle 121 at its thickest point in the thickness direction Z, so that the air nozzle 121 can be accommodated in the mounting groove 1301.

[0085] When the airbag structure 120 is a dual-airbag design, both the first fixing part 1211a and the second fixing part 1211b can be assembled into the mounting groove 1301 from the thickness direction Z. The mounting groove 1301 can also form two openings on its second surface 1312 to avoid obstructing the first airbag body 122a and the second airbag body 122b. It is understood that when the airbag structure 120 is a single-airbag design, the mounting groove 1301 can be adapted to be smaller to accommodate either the first fixing part 1211a or the second fixing part 1211b alone, improving the installation compatibility of the mounting groove 1301 and the fixing part 1211.

[0086] A positioning post 131a may also be provided on the bottom wall of the mounting groove 1301. When the fixing part 1211 is assembled in the mounting groove 1301, the positioning post 131a can be inserted into the positioning hole 1203 to achieve the positioning assembly of the mounting base 131 and the fixing part 1211, and to prevent the fixing part 1211 from shifting its position in the mounting groove 1301. Optionally, the positions of the positioning post 131a and the positioning hole 1203 can also be interchanged. That is, the positioning hole 1203 can be provided on the bottom wall of the mounting groove 1301, and the fixing part 1211 can be provided with the positioning post 131a. With this configuration, when the fixing part 1211 is assembled in the mounting groove 1301 from the thickness direction Z, the positioning post 131a can still be inserted into the positioning hole 1203 to achieve the positioning assembly of the mounting base 131 and the fixing part 1211.

[0087] A stud 131b may also be provided on the bottom wall of the mounting groove 1301, and the stud 131b can be used for fixed assembly with the cover plate 132. For example, the cover plate 132 may have a screw hole, and the cover plate 132 can be locked onto the stud 131b by screws passing through the stud and the screw hole, so as to achieve fixed assembly between the mounting base 131 and the cover plate 132. At the same time, a connecting post 131c may also be provided on the bottom wall of the mounting groove 1301, and the connecting post 131c can be connected to the elastic snap-fit ​​member 133. It can be used to fix the position of the elastic snap-fit ​​member 133 and provide guidance for the elastic force generated by the elastic snap-fit ​​member 133. Optionally, when the design of the positioning hole 1203 and the positioning post 131a is omitted, the stud 131b can replace the positioning post 131a to play the role of positioning assembly, and only the fixing part 1211 needs to have a matching hole.

[0088] like Figures 11 to 13 As shown, the mounting base 131 may also have a third surface 1313 disposed opposite to the second surface 1312, and the third surface 1313 may also be perpendicular to the first surface 1311. The mounting base 131 has a through groove 1302 on the third surface 1313 that communicates with the mounting groove 1301, and the through groove 1302 may also penetrate the first surface 1311 to form an opening on the first surface 1311 for avoiding the guide portion 1212. Simultaneously, the guide portion 1212 may be fitted into the through groove 1302 along the thickness direction Z with the fixing portion 1211, and the end of the guide portion 1212 away from the fixing portion 1211 may also protrude from the third surface 1313 in the length direction L. With this configuration, when the mounting base 131 is assembled onto the device body 200 along the length direction L, the end of the conducting portion 1212 away from the fixing portion 1211 can be inserted into the device body 200 along the length direction L to connect the device body 200 and the cavity 1201. In this embodiment, the third surface 1313 can also be connected to the first surface 1311. Of course, the two can also be perpendicular to each other without being connected.

[0089] When the airbag structure 120 is a dual-airbag design, the through slot 1302 can also be configured as two corresponding slots. For example... Figures 11 to 13 As shown, the through groove 1302 may include a first through groove 1302a and a second through groove 1302b. The first through groove 1302a can be used to avoid the first conductive part 1212a, allowing the first conductive part 1212a to protrude beyond the mounting base 131. The second through groove 1302b can be used to avoid the second conductive part 1212b, allowing the second conductive part 1212b to protrude beyond the mounting base 131. In this embodiment, the first through groove 1302a and the second through groove 1302b may also be symmetrically arranged about the length direction L, and their specific arrangement can be referred to the through groove 1302 in the previous embodiment, which will not be repeated here.

[0090] like Figures 11 to 13 As shown, the mounting base 131 may also have a fourth surface 1314 disposed opposite to the first surface 1311, and the fourth surface 1314 may be perpendicular to the second surface 1312 and the third surface 1313. When the mounting base 131 is assembled onto the device body 200 along the length direction L, the fourth surface 1314 may be exposed outside the device body 200 along the thickness direction Z, and the user can apply a force along the length direction L to the mounting base 131 through the fourth surface 1314 to detach the mounting base 131 from the device body 200 along the length direction L. Simultaneously, to increase the friction between the fourth surface 1314 and the user's finger, the mounting base 131 may also have a friction portion 131d on the fourth surface 1314 to improve the roughness of the fourth surface 1314. In this embodiment, the fourth surface 1314 may be connected to both the second surface 1312 and the third surface 1313. Of course, the fourth surface 1314 may also be perpendicular to the second surface 1312 and the third surface 1313 without being connected.

[0091] The friction part 131d can specifically be a plurality of protrusions formed on the fourth surface 1314. When the user applies a force parallel to the length direction L to the fourth surface 1314, the design of the friction part 131d can increase the friction between the user's fingers and the fourth surface 1314, so as to facilitate the user's disassembly of the mounting base 131. Of course, in addition to protrusions, the friction part 131d can also be a plurality of strip-shaped structures arranged along the length direction L on the fourth surface 1314, as long as the friction part 131d can improve the roughness of the fourth surface 1314, this embodiment does not limit it in this way.

[0092] like Figures 11 to 13As shown, the mounting base 131 may also have a fifth surface 1315 and a sixth surface 1316 that are relatively arranged and parallel to the length direction L, and both the fifth surface 1315 and the sixth surface 1316 are perpendicular to the first surface 1311. Each of the fifth surface 1315 and the sixth surface 1316 is provided with a groove 1303, which can also penetrate the side of the mounting base 131 facing away from the second surface 1312 (the third surface 1313), forming an opening on the third surface 1313. When the mounting base 131 is assembled onto the device body 200 from the length direction L, the corresponding structural component on the device body 200 can slide from the opening on the third surface 1313 into the groove 1303 on the fifth surface 1315 and the sixth surface 1316, and can slide within the groove 1303 along the length direction L, thereby achieving the positioning and assembly of the mounting base 131 and the device body 200 in the length direction L. Meanwhile, the structural components on the equipment body 200 can also be engaged with the inner wall of the slide groove 1303 in the thickness direction Z to prevent the mounting base 131 from coming off the equipment body 200 in the thickness direction Z.

[0093] In this embodiment, when the mounting base 131 is assembled in place, the structural components on the device body 200 can slide precisely to the limit position within the slide groove 1303, that is, the position where they contact the inner sidewall of the slide groove 1303 perpendicular to the length direction L. Simultaneously, the fifth surface 1315 can be connected to the first surface 1311, the second surface 1312, the third surface 1313, and the fourth surface 1314, respectively, as can the sixth surface 1316. Optionally, when the mounting base 131 is assembled in place, the structural components on the device body 200 may not slide to the limit position within the slide groove 1303. Furthermore, the fifth surface 1315 and the sixth surface 1316 may only be perpendicular to the first surface 1311, without being connected to the first surface 1311, the second surface 1312, the third surface 1313, and the fourth surface 1314.

[0094] The cover plate 132 can be connected to the mounting base 131 in the thickness direction Z and cover the mounting groove 1301. The cover plate 132 can restrict the fixing part 1211 within the mounting groove 1301 to prevent the fixing part 1211 from coming out of the mounting groove 1301 in the thickness direction Z. Figures 10 to 12 As shown, the mounting base 131 may have a mating groove 1304 on its first surface 1311, and the mounting groove 1301 may be formed on the bottom wall of the mating groove 1304. Simultaneously, at least a portion of the mating groove 1304 may penetrate the second surface 1312, forming an opening on the second surface 1312. When the fixing part 1211 is assembled into the mounting groove 1301 from the thickness direction Z, the opening formed by the mating groove 1304 on the second surface 1312 can avoid the airbag body 122 connected to the fixing part 1211.

[0095] The cover plate 132 can be assembled into the mating groove 1304 in the thickness direction Z and cover the mounting groove 1301. The cover plate 132 can be fastened to the stud 131b on the bottom wall of the mounting groove 1301 with screws. At the same time, the cover plate 132 and the bottom wall of the mounting groove 1301 can clamp the fixing part 1211 and the airbag body 122 in the middle, thereby restricting the position of the fixing part 1211. In addition, the depth of the mating groove 1304 can be greater than or equal to the thickness of the cover plate 132 to avoid the cover plate 132 forming a protrusion on the first surface 1311, resulting in an assembly gap between the first surface 1311 and the device body 200. In this embodiment, the depth of the mating groove 1304 can be equal to the thickness of the cover plate 132, so that the cover plate 132 can be flush with the first surface 1311 in the thickness direction Z.

[0096] Optionally, the design of stud 131b can be omitted, and the cover plate 132 can also be installed in the mating groove 1304 by means of bonding, welding, or snap-fitting. This embodiment does not limit this. Optionally, the design of the mating groove 1304 can also be omitted, and the cover plate 132 can also be directly provided on the first surface 1311, as long as the cover plate 132 can cover the mounting groove 1301 to restrict the fixing part 1211. Optionally, the design of the cover plate 132 can also be omitted, and the fixing part 1211 can also be fixed in the mounting groove 1301 by means of bonding, welding, snap-fitting, or screw connection. This embodiment does not limit this.

[0097] like Figure 10 and Figure 14 As shown, the cover plate 132 may also have a through hole 1305, which penetrates the cover plate 132 in the thickness direction Z and communicates with the mounting groove 1301. The through hole 1305 can be used to avoid the elastic snap-fit ​​member 133, allowing the elastic snap-fit ​​member 133 to pass through the cover plate 132 in the thickness direction Z and protrude from the cover plate 132, so that the elastic snap-fit ​​member 133 can be detachably connected to the device body 200. In this embodiment, when the thickness of the cover plate 132 is less than the depth of the mating groove 1304, the elastic snap-fit ​​member 133 not only needs to protrude from the cover plate 132, but also needs to protrude from the first surface 1311 to avoid insufficient protrusion height of the elastic snap-fit ​​member 133, which would prevent it from engaging with the device body 200.

[0098] The flexible snap-fit ​​element 133 can be disposed on the mounting base 131, and can be snapped with the equipment body 200 in the length direction L after the mounting base 131 is assembled onto the equipment body 200. When the user applies a force parallel to the length direction L to the mounting base 131, the flexible snap-fit ​​element 133 can release its snap-fit ​​state with the equipment body 200. Figures 10 to 11 As shown, the elastic snap-fit ​​member 133 can be disposed within the mounting groove 1301 and protrude from the cover plate 132 in the thickness direction Z. When the mounting base 131 is assembled onto the device body 200, the device body 200 can press against the elastic snap-fit ​​member 133 in the thickness direction Z, causing the elastic snap-fit ​​member 133 to elastically deform, displace into the mounting groove 1301, and retract into the through hole 1305. When the mounting base 131 is fully assembled, the elastic snap-fit ​​member 133 can displace out of the mounting groove 1301 under elastic force and protrude from the cover plate 132 to snap against the device body 200 in the length direction L. When the user applies a force parallel to the length direction L to the mounting base 131 through the fourth surface 1314, the elastic snap-fit ​​member 133 can retract back into the through hole 1305 under the pressure of the device body 200, thus releasing the snap-fit ​​state between the elastic snap-fit ​​member 133 and the device body 200. With this configuration, the mounting base 131 and the device body 200 can be detachably connected via the elastic snap-fit ​​connector 133, thereby improving the ease of disassembly and reassembly of the mounting base 131 and the device body 200.

[0099] like Figures 10 to 11 as well as Figure 14 As shown, the elastic snap-fit ​​element 133 may include a snap-fit ​​element 1331 and an elastic element 1332. The snap-fit ​​element 1331 may be located within the mounting groove 1301 and may be fitted into the through hole 1305 from the side of the cover plate 132 facing the mounting groove 1301. The snap-fit ​​element 1331 may also protrude from the cover plate 132 through the through hole 1305. Simultaneously, the snap-fit ​​element 1331 may also engage with the cover plate 132 in a direction away from the bottom wall of the mounting groove 1301 to prevent the snap-fit ​​element 1331 from dislodging from the through hole 1305. The elastic element 1332 may be located within the mounting groove 1301 and connects the connecting post 131c on the bottom wall of the mounting groove 1301 to the snap-fit ​​element 1331. The elastic element 1332 may generate a spring force to maintain the snap-fit ​​element 1331 protruding from the cover plate 132.

[0100] With the above configuration, when the mounting base 131 is assembled onto the device body 200 along the length direction L, the device body 200 can press against the snap-fit ​​member 1331 protruding from the cover plate 132, causing the snap-fit ​​member 1331 to move into the mounting groove 1301, and the snap-fit ​​member 1331 can retract into the through hole 1305 after displacement. At this time, because the snap-fit ​​member 1331 moves into the mounting groove 1301, the elastic member 1332 will be pressed by the snap-fit ​​member 1331 and undergo elastic deformation. When the mounting base 131 is assembled in place, the snap-fit ​​member 1331 can move out of the mounting groove 1301 under the elastic force generated by the elastic member 1332, and protrude from the cover plate 132, and can also snap into the corresponding structure of the device body 200, so as to realize the snap-fit ​​between the mounting base 131 and the device body 200 along the length direction L. Similarly, when the user applies a force parallel to the length direction L to the mounting base 131 through the fourth surface 1314, the snap-fit ​​member 1331 can repeat the aforementioned action process to release the snap-fit ​​state with the device body 200. After the user removes the mounting base 131, the snap-fit ​​member 1331 can be reset to the state protruding from the cover plate 132 under the elastic force of the elastic member 1332, thus completing the preparation for the next assembly.

[0101] Specifically, the snap-fit ​​component 1331 may include a convex cap 1331a and a convex edge 1331b. The convex cap 1331a may be located within the through hole 1305 and protrude from the cover plate 132. The convex edge 1331b may be connected to the periphery of the convex cap 1331a and located on the side of the cover plate 132 facing the mounting groove 1301. One end of the elastic element 1332 may be connected to the convex cap 1331a, and the elastic element 1332 may generate elastic force to keep the convex cap 1331a protruding from the cover plate 132, and to keep the convex edge 1331b pressed against the cover plate 132, preventing the convex cap 1331a from dislodging from the through hole 1305. In this embodiment, the elastic element 1332 may specifically be a spring, and one end of the elastic element 1332 may be sleeved on the connecting post 131c, and the other end may be connected to the convex cap 1331a. Of course, the elastic element 1332 is not limited to a spring; it only needs to generate elastic force to drive the convex cap 1331a to reset. For example, the elastic element 1332 can also be an elastic pad (such as a silicone pad, rubber pad, etc.) filled between the bottom wall of the mounting groove 1301 and the cover plate 132 to generate elastic force.

[0102] Optionally, a hole may be provided on the bottom wall of the mounting groove 1301, and one end of the elastic member 1332 may also be provided in the hole to fix it and provide guidance for the generated elastic force. In this case, the design of the connecting post 131c can be omitted. Optionally, the snap-fit ​​member 1331 may also be a sphere, and the diameter of the snap-fit ​​member 1331 may be slightly larger than the diameter of the through hole 1305, so that the snap-fit ​​member 1331 can protrude from the cover plate 132 while also being snapped into the through hole 1305, so as to prevent the snap-fit ​​member 1331 from falling out of the through hole 1305 under the influence of elastic force or gravity.

[0103] Please see Figure 15 , Figure 15 yes Figure 10 A schematic diagram of another cross-section of the central airbag structure 120 and the connecting structure 130 along VI-VI.

[0104] Optionally, the fixing part 1211 can be fitted into the mounting groove 1301 not only from the thickness direction Z, but also from the length direction L. For example... Figure 15 Therefore, the entire area of ​​the mounting groove 1301 can penetrate the second surface 1312 to form an opening on the second surface 1312 through which the fixing part 1211 can pass. Simultaneously, the positioning post 131a on the bottom wall of the mounting groove 1301 can be omitted, and a limiting hole 1306 and a mounting hole 1307 can be formed on the bottom wall of the mounting groove 1301 to replace the design of the stud 131b and connecting post 131c in the aforementioned embodiment, thereby avoiding obstruction of the fixing part 1211 in the length direction L. Furthermore, the cover plate 132 can also be provided with an insertion hole 1308 opposite to the limiting hole 1306.

[0105] The fixing part 1211 can be assembled into the mounting groove 1301 along the length direction L through the opening formed on the second surface 1312 of the mounting groove 1301. The conducting part 1212 can be inserted into the through groove 1302 along the length direction L under the drive of the fixing part 1211 and protrude from the third surface 1313. After the fixing part 1211 is assembled in place, the snap-fit ​​member 1331 and the elastic member 1332 can be assembled into the mounting groove 1301 along the thickness direction Z, and one end of the elastic member 1332 can be located in the mounting hole 1307. After the snap-fit ​​member 1331 and the elastic member 1332 are installed, the cover plate 132 can be placed on the mounting groove 1301 along the thickness direction Z, and the cover plate 132 can be fixed to the mounting base 131 by fasteners A (pins or screws) that pass through the insertion hole 1308 and the limiting hole 1306. Meanwhile, fastener A can also be inserted into the fixing part 1211 to restrict the fixing part 1211 within the mounting groove 1301 and prevent the fixing part 1211 from coming out of the mounting groove 1301 in the length direction L.

[0106] When the airbag structure 120 is a dual-airbag design, the fastener A may not need to pass through the fixing part 1211. In this case, the fastener A can be located between the first airbag body 122a and the second airbag body 122b, and can be engaged with the portion of the first fixing part 1211a and the second fixing part 1211b in the longitudinal direction L to prevent the first fixing part 1211a and the second fixing part 1211b from coming out of the mounting groove 1301 in the longitudinal direction L. Furthermore, after the guide part 1212 is assembled in the longitudinal direction L, the through groove 1302 may not need to penetrate the first surface 1311.

[0107] Optionally, when the snap-fit ​​member 1331 and the elastic member 1332 are not disposed within the mounting groove 1301, the cover plate 132 and the mounting base 131 can also be an integral structure, and both can be integrally manufactured using appropriate processes. That is, the mounting groove 1301 can be formed on the second surface 1312 and does not penetrate the first surface 1311. To achieve a detachable connection between the mounting base 131 and the equipment body 200, the snap-fit ​​member 1331 and the elastic member 1332 can be disposed on the fifth surface 1315 and the sixth surface 1316 of the mounting base 131.

[0108] Please see Figures 16 to 19 , Figure 16 yes Figure 2 A schematic diagram of the connection structure between the intermediate connection structure 130 and the device body 200. Figure 17 yes Figure 16 A structural schematic diagram of the main body of the equipment 200. Figure 18 yes Figure 16 A schematic diagram of the cross-sectional structure of the intermediate connecting structure 130 and the equipment body 200 along VII-VII. Figure 19 yes Figure 2 A schematic diagram of the cross-sectional structure of the central airbag structure 120, the connecting structure 130, and the equipment body 200 along section IV-IV.

[0109] The device body 200 can be detachably connected to the connecting structure 130, and can be inflated into the airbag body 122 via the air nozzle 121 to measure the user's blood pressure after the airbag body 122 inflates and blocks the blood vessels in the user's wrist. Figures 16 to 17As shown, the device body 200 may have a side surface 210 and a bottom surface 220 connected to the side surface 210. The device body 200 has a receiving groove 201 on the side surface 210, and this receiving groove 201 may penetrate the bottom surface 220, forming an opening on the bottom surface 220. Simultaneously, the receiving groove 201 can be used to accommodate a mounting base 131, and the depth of the receiving groove 201 in the length direction L may be greater than or equal to the length of the mounting base 131 in the length direction L, and the depth in the thickness direction Z may also be greater than or equal to the thickness of the mounting base 131 in the thickness direction Z. In this embodiment, the device body 200 may specifically be a meter head, and the area where the side surface 210 and the bottom surface 220 meet may also have a curved surface to achieve a smooth transition between the two.

[0110] It is understood that when the wearable device 10 is another device, the device body 200 is not limited to a meter; it only needs to be able to control the inflation of the airbag body 122 to measure blood pressure. This embodiment does not limit this. Similarly, when the wearable device 10 is another device, it is not limited to being worn on the user's wrist; it can also be worn on the user's arm or leg. This embodiment does not limit this either.

[0111] like Figures 16 to 18 As shown, the inner wall of the receiving groove 201, which is opposite to the cover plate 132, is provided with a slot 202. This slot 202 can cooperate with the snap-fit ​​member 1331 to achieve snap-fit ​​between the mounting base 131 and the equipment body 200 in the length direction L. When the mounting base 131 is inserted into the receiving groove 201 from the length direction L (i.e., from the side where side 210 is located), the inner wall of the receiving groove 201, which is opposite to the cover plate 132, can press against the snap-fit ​​member 1331, causing the snap-fit ​​member 1331 to move into the mounting groove 1301 and retract into the through hole 1305. At this time, the elastic member 1332 can undergo elastic deformation under the pressure of the snap-fit ​​member 1331 to generate a spring force for resetting. When the mounting base 131 is assembled in place, the snap-fit ​​member 1331 can be positioned opposite the slot 202 in the thickness direction Z. At this time, since there is no longer the pressure from the inner wall of the receiving groove 201, the snap-fit ​​piece 1331 can be reset under the action of elasticity and snap into the slot 202 so as to snap into the inner wall of the slot 202 in the length direction L, thereby realizing the fixed assembly of the mounting base 131 and the equipment body 200.

[0112] like Figures 16 to 18As shown, since the receiving groove 201 has an opening on the bottom surface 220, the fourth surface 1314 can be exposed on the bottom surface 220 through the opening formed by the receiving groove 201. The user can apply a force parallel to the length direction L to the fourth surface 1314 through this opening, so that the snap-fit ​​member 1331 is disengaged from the slot 202, thereby releasing the snap-fit ​​state between the snap-fit ​​member 1331 and the inner wall of the slot 202, allowing the mounting base 131 to be disengaged from the receiving groove 201 in the length direction L. Specifically, the surfaces in contact between the snap-fit ​​component 1331 and the slot 202 can be inclined or curved. When the user applies a force parallel to the length direction L to the fourth surface 1314, the surfaces in contact between the snap-fit ​​component 1331 and the slot 202 can transform the force parallel to the length direction L into a force parallel to the thickness direction Z, thereby driving the snap-fit ​​component 1331 out of the slot 202, achieving the purpose of releasing the snap-fit ​​state between the two, and thus realizing the disassembly of the mounting base 131 and the equipment body 200.

[0113] Alternatively, the receiving groove 201 may be formed only on the side 210 and not penetrate the bottom surface 220. In this case, the user can apply a force parallel to the length direction L to the mounting base 131 by pulling the airbag body 122 to release the snap-fit ​​state between the snap-fit ​​member 1331 and the inner wall of the slot 202, thereby realizing the disassembly of the device body 200 and the mounting base 131.

[0114] like Figure 17 and Figure 19 As shown, the bottom wall of the receiving groove 201, which is opposite to the third surface 1313, may be provided with an air hole 203, which can be connected to an air pump. After the mounting base 131 is assembled in the receiving groove 201, the connecting part 1212 can be inserted into the air hole 203 along the length direction L to connect the cavity 1201 of the device body 200 and the airbag body 122, so that the device body 200 can inflate the cavity 1201 to expand the airbag body 122. When the connecting part 1212 is inserted into the air hole 203, the sealing ring 1213 can interfere with the inner wall of the air hole 203 to improve the airtightness after the connection between the two.

[0115] When the airbag structure 120 is a dual-airbag design, the air vents 203 may include a first air vent 203a and a second air vent 203b. A first conductive portion 1212a can be inserted into the first air vent 203a along its length L to connect the device body 200 and the first airbag body 122a. A second conductive portion 1212b can also be inserted into the second air vent 203b along its length L to connect the device body 200 and the second airbag body 122b. With this configuration, the device body 200 can inflate both the first airbag body 122a and the second airbag body 122b.

[0116] It is understandable that when the airbag structure 120 is a single airbag, the air vent 203 may include only the first air vent 203a or the second air vent 203b to connect to the single airbag body 122. In this case, the "air vent" can also be called the "first air vent" or the "second air vent", and the "first air vent" can also be called the "second air vent", and the "second air vent" can also be called the "first air vent".

[0117] like Figure 17 and Figure 19 As shown, the receiving groove 201 has sliders 230 on its two inner sidewalls, which are respectively positioned opposite to the fifth surface 1315 and the sixth surface 1316. When the mounting base 131 is assembled into the receiving groove 201, the sliders 230 can be inserted into the slide groove 1303 through the opening formed on the third surface 1313, and can slide along the length direction L within the slide groove 1303. Simultaneously, the sliders 230 can also engage with the inner wall of the slide groove 1303 in the thickness direction Z to prevent the mounting base 131 from dislodging from the opening formed on the bottom surface 220 of the receiving groove 201. Furthermore, when the mounting base 131 is fully assembled, the sliders 230 can slide to their limit position within the slide groove 1303, that is, the position where they contact the inner sidewall of the slide groove 1303 perpendicular to the length direction L.

[0118] With the above configuration, the device body 200 can be detachably connected in the length direction L to the elastic snap-fit ​​member 133 on the mounting base 131 via the slot 202 provided on the inner side wall of the receiving groove 201, thereby realizing the detachable connection between the airbag structure 120 and the device body 200 in the length direction L. Simultaneously, by providing an opening on the bottom surface of the receiving groove 201 to expose the fourth surface 1314, it is easier for the user to apply a force parallel to the length direction L to the mounting base 131, allowing for one-handed disassembly of the mounting base 131 and the device body 200, thus improving the ease of disassembly of the mounting base 131 and the device body 200.

[0119] Optionally, to further improve the assembly stability of the mounting base 131 and the equipment body 200, both the mounting base 131 and the equipment body 200 may be equipped with a magnet B. For example... Figure 19As shown, magnets B can be provided on the bottom wall of the receiving groove 201 opposite to the third surface 1313, and magnets B can also be provided on the third surface 1313 of the mounting base 131. When the mounting base 131 is assembled in the receiving groove 201, the two magnets B can attract each other to generate magnetic force to assist the mounting base 131 in positioning and assembly. After the mounting base 131 is assembled in place, the two magnets B can fit together to improve the assembly firmness of the mounting base 131 and the device body 200 in the length direction L by using magnetic force. In this embodiment, both magnets B can be magnets, or one of them can be a magnet and the other can be a metal part that can be attracted by a magnet. Optionally, the arrangement position of magnets B is not limited to the above embodiment, and its specific arrangement position can be adapted to meet the needs. In addition, the design of magnets B can also be omitted.

[0120] Please see Figures 20 to 21 , Figure 20 yes Figure 16 A schematic diagram of another section of the connecting structure 130 and the equipment body 200 along VII-VII. Figure 21 yes Figure 2 A schematic diagram of the cross-sectional structure of the central airbag structure 120, the connecting structure 130, and the equipment body 200 along another part of IV-IV.

[0121] Optionally, the positions of the slot 202 and the elastic snap-fit ​​connector 133 can be interchanged; that is, the connecting structure 130 can be provided with the slot 202, while the device body 200 can be provided with the elastic snap-fit ​​connector 133. For example... Figure 20 As shown, the through hole 1305 on the cover plate 132 can replace the slot 202 (the following description only uses the through hole 1305 to replace the slot 202), and the inner sidewall of the receiving groove 201 opposite to the cover plate 132 can be provided with a receiving hole 204. The elastic snap-fit ​​member 133 can be provided in the receiving hole 204 and protrude from the inner sidewall of the receiving groove 201 opposite to the cover plate 132. When the mounting base 131 is assembled into the receiving groove 201 in the longitudinal direction L, the cover plate 132 can press against the elastic snap-fit ​​member 133, so that the elastic snap-fit ​​member 133 retracts into the receiving hole 204 and undergoes elastic deformation. After the mounting base 131 is assembled in place, the elastic snap-fit ​​member 133 can be reset under the action of elastic force and snap into the through hole 1305 of the cover plate 132 to realize the fixed assembly of the mounting base 131 and the equipment body 200. Similarly, when the user applies a force parallel to the length direction L to the fourth surface 1314, the elastic snap-fit ​​133 can be disengaged from the through hole 1305 to achieve the disassembly of the mounting base 131 and the device body 200. Furthermore, the specific structure of the elastic snap-fit ​​133 can be found in the aforementioned embodiments and will not be repeated here.

[0122] Optionally, the positions of the slider 230 and the slide groove 1303 can be interchanged; that is, the mounting base 131 can be equipped with the slider 230, and the equipment body 200 can be equipped with the slide groove 1303. For example... Figure 21 As shown, sliders 230 can be provided on both the fifth surface 1315 and the sixth surface 1316 of the mounting base 131. Slide grooves 1303 can be formed on the two inner sidewalls of the receiving groove 201, which are respectively disposed opposite to the fifth surface 1315 and the sixth surface 1316. The slide grooves 1303 can also penetrate the side surface 210 to form an opening on the side surface 210. When the mounting base 131 is assembled into the receiving groove 201, the sliders 230 can be inserted into the slide grooves 1303 through the opening formed on the side surface 210, and can slide along the length direction L within the slide grooves 1303. They can also engage with the inner wall of the slide grooves 1303 in the thickness direction Z to prevent the mounting base 131 from dislodging from the opening on the bottom surface 220 into the receiving groove 201.

[0123] Please see Figures 22 to 23 , Figure 22 yes Figure 16 A schematic diagram of a partial cross-sectional structure of the connecting structure 130 and the equipment body 200 along XI-XI. Figure 23 yes Figure 16 A schematic diagram of another section of the connecting structure 130 and the equipment body 200 along XI-XI.

[0124] Optionally, the groove 1303 may not be limited to being provided on the fifth surface 1315 and the sixth surface 1316. For example... Figure 22 As shown, the groove 1303 can also be formed on the first surface 1311 and penetrate the third surface 1313 to form an opening on the third surface 1313. Correspondingly, a slider 230 can be provided on the inner sidewall of the receiving groove 201 opposite to the first surface 1311. When the mounting base 131 is inserted into the receiving groove 201, the slider 230 can be inserted into the groove 1303 from the opening formed on the third surface 1313, and can slide along the length direction L within the groove 1303. It can also engage with the inner wall of the groove 1303 in the thickness direction Z to prevent the mounting base 131 from falling out of the receiving groove 201 from the opening on the bottom surface 220. For example, the cross-section of the slider 230 can be an inverted triangle or an inverted trapezoid, and the shape of the groove 1303 can be adapted to the slider 230. When the slider 230 is inserted into the groove 1303, the two can engage in the thickness direction Z. In this embodiment, the positions of the slide groove 1303 and the slider 230 can also be interchanged. That is, the slider 230 is provided on the first surface 1311, while the slide groove 1303 is provided on the inner sidewall of the receiving groove 201 which is opposite to the first surface 1311. The specific arrangement of the two is the same as or similar to that in the previous embodiment, and will not be described in detail here.

[0125] Alternatively, the flexible snap-fit ​​connector 133 may not be limited to being disposed within the mounting slot 1301. For example... Figure 23 As shown, blind holes 205 can be formed on both the fifth surface 1315 and the sixth surface 1316 of the mounting base 131, and elastic snap-fit ​​members 133 can be provided in both blind holes 205 of the fifth surface 1315 and the sixth surface 1316. Correspondingly, slots 202 can be provided on the inner sidewalls of the receiving groove 201 that are respectively opposite to the fifth surface 1315 and the sixth surface 1316. The following description only takes the elastic snap-fit ​​member 133 provided on the fifth surface 1315 as an example. The elastic snap-fit ​​member 133 can be provided in the blind hole 205 and protrude from the fifth surface 1315. When the mounting base 131 is inserted into the receiving groove 201, the inner sidewall of the receiving groove 201 opposite to the fifth surface 1315 can press against the elastic snap-fit ​​member 133, so that the elastic snap-fit ​​member 133 retracts into the blind hole 205 and undergoes elastic deformation. Once the mounting base 131 is in place, the elastic snap-fit ​​member 133 can be reset under the action of elastic force and snap into the slot 202 to achieve a fixed assembly of the mounting base 131 and the equipment body 200. Furthermore, the specific structure of the elastic snap-fit ​​member 133 can be found in the aforementioned embodiments and will not be repeated here.

[0126] Similarly, when the user applies a force parallel to the length direction L to the fourth surface 1314, the elastic snap-fit ​​133 can be withdrawn from the slot 202 to disassemble the mounting base 131 and the device body 200. In this embodiment, the positions of the elastic snap-fit ​​133 and the slot 202 can also be interchanged. That is, the fifth surface 1315 and the sixth surface 1316 are provided with slots 202, and the two inner sidewalls of the receiving groove 201 opposite to the fifth surface 1315 and the sixth surface 1316 can be provided with blind holes 205 and elastic snap-fit ​​133 located in the blind holes 205. The specific arrangement of the elastic snap-fit ​​133 and the slot 202 is the same as or similar to that in the previous embodiment, and will not be described in detail here.
