[0016] 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.

[0017] 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.

[0018] See also Figure 1 to Figure 2 , 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 Another structural schematic diagram of the wearable device 10.

[0019] The wearable device 10 provided in the present application may be a smart watch, a smart bracelet, or a cuff-type blood pressure measuring device, etc., and the following only takes the wearable device 10 as a smart watch as an example. Figure 1 to Figure 2 As shown, the wearable device 10 may include: a main body 100 and a strap mechanism 200. The two opposite sides of the main body 100 may be connected to the strap mechanism 200 respectively, and can be enclosed together with the strap mechanism 200 to form a wearing space 300 for accommodating the user's wrist, and the main body 100 may also be integrated with various functional devices required for the wearable device 10, such as an air pump, a speaker, a microphone, a display screen, a camera, and a battery, etc. The strap mechanism 200 may be connected to the main body 100, and the strap mechanism 200 may be tied to the user's wrist, and can expand and compress the user's wrist under the control of the main body 100, so as to cooperate with the main body 100 to measure the user's blood pressure.

[0020] Exemplarily, the main body 100 may be a watch head of a smart watch, and the main body 100 may be arranged roughly in a rectangular shape, and may include: a top surface 101 and a bottom surface 102 arranged opposite to each other, and a side surface 103 respectively connecting the top surface 101 and the bottom surface 102. Among them, the top surface 101 may be arranged away from the wearing space 300, and the top surface 101 may also be the display surface of the main body 100 to realize the display function of the wearable device 10. The bottom surface 102 is arranged close to the wearing space 300, and the bottom surface 102 may be used to install a light detection module and / or a bioelectric detection module to respectively realize the blood pressure and / or heart rate detection functions of the wearable device 10.

[0021] Further, the side surface 103 can be connected to the strap mechanism 200, and the side surface 103 can also be used to install structures such as knobs or buttons. For example, the side surface 103 can include: a first side surface 1031 and a second side surface 1032 that are opposite and spaced apart, and a third side surface 1033 and a fourth side surface 1034 that are respectively connected to the first side surface 1031 and the second side surface 1032 and are opposite and spaced apart. Among them, the first side surface 1031 and the second side surface 1032 can be used to connect to the strap mechanism 200, and the third side surface 1033 and the fourth side surface 1034 can be used to install knobs or buttons. At the same time, an air hole that is connected to the air pump in the main body mechanism 100 can also be opened on the first side surface 1031, and the air hole can be inserted into the strap mechanism 200 to connect the strap mechanism 200 and the air pump, so that the strap mechanism 200 can expand or contract under the control of the main body mechanism 100.

[0022] Optionally, the main body 100 may be provided with a receiving groove for accommodating the strap mechanism 200 on the first side surface 1031 and the second side surface 1032, and the main body 100 may be provided with a clamping structure located on the bottom surface 102 and inserted into the receiving groove. When the strap mechanism 200 is inserted into the receiving groove, the strap mechanism 200 can be clamped with the clamping structure in the receiving groove in the direction of exiting the receiving groove. At the same time, the user can also press the clamping structure on the bottom surface 102 to slide to release the clamping state between the clamping structure and the strap mechanism 200, thereby realizing a detachable connection between the strap mechanism 200 and the main body 100. In addition, an air hole can be opened on the bottom wall of the receiving groove, so that the strap mechanism 200 can be inserted into the air hole while being detachably connected with the main body 100, so as to realize the connection between the strap mechanism 200 and the main body 100.

[0023] Optionally, the detachable connection method of the main body mechanism 100 and the strap mechanism 200 may not be limited to this. For example, the main body mechanism 100 and the strap mechanism 200 may also be detachably connected by a combination of ear pins and ear holes. Of course, the main body mechanism 100 and the strap mechanism 200 may also be non-detachably connected, rather than being limited to a detachable connection. In addition, in addition to being a rectangular header, the main body mechanism 100 may also be a circular header or an elliptical header, or an irregularly shaped header, which is not limited in this embodiment.

[0024] 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.

[0025] Please combine Figure 1 to Figure 2 See also Figures 3 to 6 , Figure 3 yes Figure 1 A schematic diagram of a partial cross-sectional structure of the wearable device 10 along V-V, Figure 4 yes Figure 3 The structural diagram of the middle connecting buckle 211, Figure 5 yes Figure 4 Another structural diagram of the middle connecting buckle 211, Figure 6 yes Figure 5 A schematic structural diagram of the middle connecting buckle 211 from another viewing angle.

[0026] The strap mechanism 200 can be connected to opposite sides of the main body mechanism 100, and can be enclosed together with the main body mechanism 100 to form a wearing space 300, and the strap mechanism 200 can also expand under the control of the main body mechanism 100 to compress the user's wrist. Figures 2 to 3As shown, the strap mechanism 200 may include: a strap assembly 210 and an airbag assembly 220. Among them, one end of the strap assembly 210 can be connected to the main body 100 from the second side 1032, and one end of the airbag assembly 220 can be connected to the main body 100 from the first side 1031. At the same time, the other end of the strap assembly 210 can also overlap with the other end of the airbag assembly 220, and the strap assembly 210, the airbag assembly 220 and the main body 100 can be jointly surrounded to form the aforementioned wearing space 300. In addition, one end of the airbag assembly 220 connected to the main body 100 can also be inserted into the air hole, so that the airbag assembly 220 can expand or contract under the control of the main body 100. In this embodiment, the strap assembly 210 can avoid the expansion of the airbag assembly 220 while achieving overlap with the airbag assembly 220, so as to avoid the strap assembly 210 and the airbag assembly 220 overlapping to limit the expansion of the airbag assembly 220.

[0027] Furthermore, the strap assembly 210 may include: a connecting buckle 211 and a first strap 212. The connecting buckle 211 is connected to the end of the first strap 212, and a limiting space 2101 is formed to allow one end of the airbag assembly 220 to pass through, and the end of the first strap 212 away from the connecting buckle 211 can also be connected to the main body 100 from the second side surface 1032. At the same time, after one end of the airbag assembly 220 passes through the limiting space 2101, the first strap 212 can also overlap with the airbag assembly 220, and together with the airbag assembly 220 and the main body 100, form a wearing space 300. In addition, the connecting buckle 211 may also be provided with a notch 2102 connected to the limiting space 2101, and the notch 2102 may be located on the side of the airbag assembly 220 away from the first strap 212, so as to prevent the airbag assembly 220 from expanding in a direction away from the first strap 212, that is, toward the wearing space 300. With such a configuration, not only can the connecting buckle 211 be used to connect the first strap 212 and the airbag assembly 220, but also the connecting buckle 211 may be prevented from limiting the expansion of the airbag assembly 220.

[0028] Furthermore, the connecting buckle 211 is also located on the side of the first strap 212 close to the wearing space 300, so that one end of the airbag assembly 220 can also overlap on the side of the first strap 212 close to the wearing space 300 after passing through the limiting space 2101, so that the airbag assembly 220 can expand toward the wearing space 300, thereby pressing the user's wrist. At the same time, after one end of the airbag assembly 220 passes through the limiting space 2101, the airbag assembly 220 can also be engaged with the connecting buckle 211 in the direction of exiting the limiting space 2101, so as to maintain the overlapping state of the airbag assembly 220 and the first strap 212, thereby realizing a fixed connection between the airbag assembly 220 and the first strap 212. Of course, the locking state of the airbag assembly 220 and the connecting buckle 211 can also be released, so that the airbag assembly 220 can withdraw from the limiting space 2101 to separate from the first strap 212, thereby removing the airbag assembly 220 and the first strap 212 from the user's wrist.

[0029] Exemplarily, the connecting buckle 211 may include: a main body 2111, a limiting portion 2112 and a connecting portion 2113. Figures 3 to 5 As shown, the main body 2111 can be connected to the end of the first strap 212 and is located on the side of the first strap 212 close to the wearing space 300. The limiting portion 2112 is provided on the side of the main body 2111 away from the first strap 212, and is opposite to and spaced from the main body 2111. The connecting portion 2113 is located between the limiting portion 2112 and the main body 2111, and is connected to the limiting portion 2112 and the main body 2111 respectively, and the connecting portion 2113 can also be enclosed together with the main body 2111 and the limiting portion 2112 to form a limiting space 2101.

[0030] Furthermore, the limiting portion 2112 can contact the airbag assembly 220 in the direction in which the airbag assembly 220 is away from the first tether 212, so as to limit the displacement of the airbag assembly 220 in the direction away from the first tether 212. At the same time, a notch 2102 can be provided on the side of the limiting portion 2112 away from the main body 2111, and the limiting portion 2112 can be disconnected at the notch 2102 to be divided into two areas to respectively limit the displacement of the airbag assembly 220 in the direction away from the first tether 212. In addition, the size of the notch 2102 can be consistent with the size of the airbag assembly 220 after expansion, or slightly larger than the size of the airbag assembly 220 after expansion, so that the notch 2102 can avoid the expansion of the airbag assembly 220, thereby preventing the limiting portion 2112 from binding the airbag assembly 220.

[0031] Further, the connection part 2113 can contact the airbag assembly 220 in the width direction of the airbag assembly 220 to limit the displacement of the airbag assembly 220 in the width direction. For example, the connection part 2113 may include: a first connection part 2113a and a second connection part 2113b. Among them, the first connection part 2113a and the second connection part 2113b can be connected to the main body 2111 and the limiting part 2112 respectively, and can be enclosed together with the main body 2111 and the limiting part 2112 to form a limiting space 2101. At the same time, the first connection part 2113a and the second connection part 2113b can also be arranged oppositely and at intervals, and when the airbag assembly 220 passes through the limiting space 2101, the first connection part 2113a and the second connection part 2113b are also located on the opposite sides of the airbag assembly 220 in the width direction, and can contact the airbag assembly 220 to limit the displacement of the airbag assembly 220 in the width direction.

[0032] Furthermore, in order to be able to engage with the airbag assembly 220 passing through the limiting space 2101, the connecting buckle 211 may also include: a positioning portion 2114, and when the airbag assembly 220 passes through the limiting space 2101, the positioning portion 2114 can engage with the airbag assembly 220 in the direction of exiting the limiting space 2101, so as to maintain the overlapping state of the airbag assembly 220 and the first tether 212. Figures 3 to 6 As shown, the positioning portion 2114 can be arranged on one side of the main body 2111 close to the limiting portion 2112 and outside the limiting space 2101, so as to prevent the positioning portion 2114 from affecting the airbag assembly 220 passing through the limiting space 2101. At the same time, after the airbag assembly 220 passes through the limiting space 2101, the airbag assembly 220 can be arranged opposite to the positioning portion 2114, and the positioning portion 2114 can also be inserted into the airbag assembly 220 to engage with the airbag assembly 220 in the direction of exiting the limiting space 2101, thereby maintaining the overlapping state of the airbag assembly 220 and the first tether 212.

[0033] Optionally, the positioning portion 2114 can also be located outside the coverage of the positive projection of the expansion area of ​​the airbag assembly 220 on the main body 2111, so as to avoid the positioning portion 2114 from affecting the expansion area of ​​the airbag assembly 220 when it is inserted on the airbag assembly 220, and it is also beneficial to reduce the overall thickness of the airbag assembly 220.

[0034] Optionally, the number of the positioning parts 2114 can also be multiple, such as two, three, four or more. For example, the number of the positioning parts 2114 can be two, and the two positioning parts 2114 can be arranged oppositely and spaced apart to form a spacing space between the two positioning parts 2114, so as to use the spacing space to avoid the expansion area of ​​the airbag assembly 220. That is, the orthographic projection of the expansion area of ​​the airbag assembly 220 on the main body 2111 is located between the two positioning parts 2114, so as to avoid the two positioning parts 2114 from affecting the expansion area of ​​the airbag assembly 220.

[0035] Optionally, the positioning portion 2114 may also be located within the coverage of the orthographic projection of the expansion area of ​​the airbag assembly 220 on the main body 2111. In this case, the thickness of the portion of the airbag assembly 220 between its expansion area and the positioning portion 2114 needs to be thickened to ensure that the airbag assembly 220 has sufficient thickness for the positioning portion 2114 to be inserted without affecting the expansion area of ​​the airbag assembly 220.

[0036] Optionally, in some embodiments, the airbag assembly 220 may also be snap-fitted with the first strap 212, rather than being limited to being snap-fitted with the connecting buckle 211. For example, a hole may be provided on the first strap 212, and a protrusion may be provided at one end of the airbag assembly 220 that passes through the limiting space 2101, and the end size of the protrusion may be larger than the size of the hole, and may force the first strap 212 to deform when inserted into the hole, so that the first strap 212 is snap-fitted in the direction of exiting the hole, thereby achieving the snap-fitting of the airbag assembly 220 and the first strap 212 in the direction of exiting the limiting space 2101. In this case, the design of the positioning portion 2114 may be omitted.

[0037] Furthermore, in order to improve the convenience of use of the connection buckle 211, the connection buckle 211 may also include: a fixing portion 2115 and a rotating portion 2116. Figure 3 to Figure 4As shown, one side of the fixing portion 2115 can be connected to the end of the first strap 212, and the fixing portion 2115 is also located on the side of the first strap 212 close to the wearing space 300. The rotating portion 2116 can be arranged on the other opposite side of the fixing portion 2115 and protrude from the fixing portion 2115, and the rotating portion 2116 can be specifically a rotating shaft. The main body 2111 can be sleeved on the rotating portion 2116 and can be rotated relative to the rotating portion 2116 to be folded and buckled to the side of the fixing portion 2115 away from the first strap 212, and the limiting portion 2112 and the positioning portion 2114 are both located on the side of the main body 2111 away from the fixing portion 2115. For example, the main body 2111 is provided with an avoidance groove, and a partial area of ​​the fixing part 2115 can be arranged in the avoidance groove, and the rotating part 2116 can be simultaneously penetrated through the main body 2111 and the fixing part 2115 to realize the rotational connection between the main body 2111 and the fixing part 2115.

[0038] Optionally, in order to enable the main body 2111 to be buckled on the fixing portion 2115, a rivet 2117 is further provided on the side of the main body 2111 away from the limiting portion 2112, and a buckle position 2118 is provided on the side of the fixing portion 2115 away from the first strap 212. When the main body 2111 is rotated and folded with the fixing portion 2115, the rivet 2117 can be buckled with the buckle position 2118 to maintain the folded state of the main body 2111 and the fixing portion 2115. Of course, in addition to the combination of the rivet 2117 and the buckle position 2118, the main body 2111 and the fixing portion 2115 can also be maintained in the folded state by other fixing methods, which is not limited in this embodiment.

[0039] Through the above arrangement, when the user needs to wear the wearable device 10, the user can rotate the main body 2111 to a suitable position so that the airbag assembly 220 can pass through the limiting space 2101 and engage with the positioning portion 2114. After the airbag assembly 220 and the positioning portion 2114 are engaged, the user can snap the fixing portion 2115 onto the main body 2111 to reduce the wearing space 300, so that the airbag assembly 220 and the first strap 212 can fit the user's wrist, thereby completing the wearing of the wearable device 10. Similarly, when the user needs to take off the wearable device 10, the user can pull the fixing portion 2115 off the main body 2111 to expand the wearing space 300, so that the user can more conveniently release the engagement state of the airbag assembly 220 and the positioning portion 2114, and pull the airbag assembly 220 out of the limiting space 2101.

[0040] It can be understood that the specific structure of the aforementioned connecting buckle 211 is only for illustrative purposes and is not limited to the aforementioned embodiments, and the specific structure of the connecting buckle 211 can also be adaptively adjusted according to design requirements. It is only necessary for the connecting buckle 211 to surround and form a limited space 2101 and to provide a notch 2102 for avoiding the airbag assembly 220. This embodiment is not listed one by one here.

[0041] Optionally, the end of the first strap 212 away from the connecting buckle 211 can be detachably connected to the main body 100 from the second side surface 1032. For example, an ear pin can be provided on the end of the first strap 212 away from the connecting buckle 211, and the main body 100 is provided with an ear hole on the groove wall of the receiving groove on the second side surface 1032, so as to realize the detachable connection between the first strap 212 and the main body 100 by using the combination of the ear pin and the ear hole. Of course, the detachable connection method between the first strap 212 and the main body 100 may not be limited to this, or the first strap 212 and the main body 100 may also be non-detachably connected, which is not limited in this embodiment.

[0042] Optionally, in order to improve the air permeability of the strap mechanism 200, the first strap 212 is further provided with a heat dissipation hole 2121 connected to the wearing space 300. Figure 1 to Figure 2 As shown, the heat dissipation holes 2121 can penetrate the opposite sides of the first strap 212 in the thickness direction of the first strap 212, and the number of the heat dissipation holes 2121 can also be multiple. Among them, the multiple heat dissipation holes 2121 can be two groups of the same number, and the two groups of heat dissipation holes 2121 can be arranged on the first strap 212 at intervals, and can be arranged in sequence in the length direction of the first strap 212. Of course, there can be many ways to arrange the heat dissipation holes 2121, which are not listed one by one in this embodiment.

[0043] 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.

[0044] Please combine Figure 3 See also Figures 7 and 8 , Figure 7 yes Figure 2 A schematic diagram of the structure of the airbag assembly 220, Figure 8 yes Figure 7 Schematic diagram of the cross-sectional structure of the middle airbag assembly 220 along VI-VI.

[0045] The airbag assembly 220 can be connected to the main body 100 and the first tether 212 respectively, and can expand or contract under the control of the main body 100. Figures 7 and 8 As shown, the airbag assembly 220 may include: a second strap 221 and an airbag 222. One end of the second strap 221 can pass through the limiting space 2101 and overlap with the first strap 212, and can be engaged with the connecting buckle 211 in the direction of exiting the limiting space 2101 to maintain the overlapping state of the first strap 212 and the second strap 221. At the same time, the other end of the second strap 221 is also connected to the main body 100 from the first side 1031, so that the second strap 221, the first strap 212 and the main body 100 can be jointly surrounded to form a wearing space 300. The airbag 222 is arranged on the side of the second strap 221 away from the first strap 212, and the airbag 222 is also connected to the main body 100, and can expand or contract under the control of the main body 100. In addition, the airbag 222 can also pass through the limiting space 2101 synchronously with the second strap 221, and the notch 2102 is located on the side of the airbag 222 away from the first strap 212 to avoid the expansion of the airbag 222 in the direction of the second strap 221 away from the first strap 212, that is, toward the wearing space 300.

[0046] Exemplarily, the second strap 221 has a matching portion 2211, and when the second strap 221 passes through the limiting space 2101, the matching portion 2211 can be engaged with the positioning portion 2114 in the direction in which the second strap 221 exits the limiting space 2101. Figure 3 As shown, after the second strap 221 passes through the limiting space 2101, the matching portion 2211 can be arranged opposite to the positioning portion 2114, and the matching portion 2211 is also provided with a positioning hole 2201, and the positioning portion 2114 can be inserted into the positioning hole 2201 to engage with the side wall of the positioning hole 2201, thereby limiting the second strap 221 from exiting the limiting space 2101. At the same time, the number of positioning holes 2201 can also be multiple, and the multiple positioning holes 2201 can be arranged in sequence along the length direction of the second strap 221, so that the user can adjust the relative position of the first strap 212 and the second strap 221 through the multiple positioning holes 2201. In addition, the positioning hole 2201 can pass through the matching portion 2211 in the thickness direction of the second strap 221, that is, the positioning hole 2201 can be a through hole. Of course, in some embodiments, the positioning hole 2201 can also be a blind hole, and it is only necessary that the positioning portion 2114 can be inserted into the positioning hole 2201.

[0047] Optionally, in addition to the positioning hole 2201 provided in the matching portion 2211 for the positioning portion 2114 to be inserted, the positioning portion 2114 may also be provided with a positioning hole 2201, and the matching portion 2211 may be inserted into the positioning hole 2201 and engaged with the positioning portion 2114. That is, one of the matching portion 2211 and the positioning portion 2114 is provided with a positioning hole 2201, and the other may be inserted into the positioning hole 2201 and engaged with the side wall of the positioning hole 2201 to restrict the second lace 221 from exiting the limiting space 2101.

[0048] Optionally, in addition to the coupling between the mating portion 2211 and the positioning portion 2114 being inserted, the mating portion 2211 and the positioning portion 2114 can also be coupled by meshing. For example, a serrated structure can be formed on the mating portion 2211, and the positioning portion 2114 can also be a serrated structure corresponding to the mating portion 2211, and when the second strap 221 passes through the limit control 2101, the serrated structures of the mating portion 2211 and the positioning portion 2114 can mesh with each other to achieve the coupling between the two when the second strap 221 exits the limit space 2101. At the same time, the serrated structure of the mating portion 2211 can be designed to be longer and arranged along the length direction of the second strap 221, while the serrated structure on the positioning portion 2114 can be designed to be shorter to mesh with the serrated structures at different positions on the mating portion 2211, so as to adjust the relative positions of the first strap 212 and the second strap 221.

[0049] Optionally, in order to engage with the positioning portion 2114, the matching portion 2211 is also located outside the coverage of the airbag 222 (the expansion area of ​​the airbag assembly 220) on the second tether 221, and can be arranged opposite to the positioning portion 2114 after the second tether 221 passes through the limiting space 2101, so that the engagement of the matching portion 2211 and the positioning portion 2114 can avoid the airbag 222. Such an arrangement can not only prevent the engagement of the matching portion 2211 and the positioning portion 2114 from affecting the expansion of the airbag 222, but also help to reduce the thickness of the airbag assembly 220 as a whole.

[0050] Optionally, when there are two positioning portions 2114, the second strap 221 has matching portions 2211 on both opposite sides parallel to the length direction thereof, and the area of ​​the second strap 221 covered by the airbag 222 is located between the two matching portions 2211. At the same time, after the second strap 221 passes through the limiting space 2101, the two positioning portions 2114 can be respectively arranged opposite to the two matching portions 2211, and can be respectively inserted into the positioning holes 2201 of the two matching portions 2211 to restrict the second strap 221 from exiting the limiting space 2101. In this arrangement, the two positioning portions 2114 are respectively engaged with the two matching portions 2211, which not only improves the secure engagement between the second strap 221 and the connecting buckle 211, but also allows the area between the two positioning portions 2114 and the two matching portions 2111 to avoid the airbag 222.

[0051] Optionally, when the positioning portion 2114 is located within the coverage of the orthographic projection of the airbag 222 on the main body 2111, the matching portion 2211 may also be located within the coverage of the airbag 222 on the second tether 221 and between the positioning portion 2114 and the airbag 222 to be engaged with the positioning portion 2114. In this case, the thickness of the matching portion 2211 may be increased to increase the depth of the positioning hole 2201 provided on the matching portion 2211, so that the positioning hole 2201 can accommodate the positioning portion 2114, thereby preventing the positioning portion 2114 from passing through the matching portion 2211 and contacting the airbag 222.

[0052] Optionally, the other end of the second tie 221 can be detachably connected to the main body 100 from the first side 1031. For example, an ear pin can be provided on the other end of the second tie 221, and the main body 100 is provided with an ear hole on the wall of the receiving groove on the first side 1031, so as to realize the detachable connection between the second tie 221 and the main body 100 by using the combination of the ear pin and the ear hole. Of course, the detachable connection method between the second tie 221 and the main body 100 may not be limited to this, or the second tie 221 and the main body 100 may also be non-detachably connected, which is not limited in this embodiment.

[0053] Exemplarily, the airbag 222 is disposed on the side of the second tether 221 away from the first tether 212 and can pass through the limiting space 2101. The airbag 222 is also connected to the main body 100 to expand or contract under the control of the main body 100. Figures 7 and 8As shown, in order to reduce the overall thickness of the airbag assembly 220, the airbag 222 can also be embedded in the second strap 221. For example, a groove 2202 is also provided on the side of the second strap 221 away from the first strap 212, that is, the side of the second strap 221 close to the wearing space 300, and the airbag 222 is also located in the groove 2202, and can be protruded from the groove 2202 after expansion to compress the wrist of the user. At the same time, the airbag 222 can also be spaced apart from the side wall of the groove 2202 to form a gap to avoid the expansion of the airbag 222. That is, the size of the groove 2202 can be slightly larger than the size of the airbag 222, so that the groove 2202 can reserve the space required for the expansion of the airbag 222 to avoid the second strap 221 from restraining the expansion of the airbag 222. In this embodiment, the airbag 222 can be a single-layer airbag or a multi-layer airbag.

[0054] Through the above arrangement, when the user does not need to measure blood pressure, the airbag 222 can be retracted in the groove 2202 to reduce the probability of the airbag 222 contacting the user's skin, thereby omitting the flexible sleeve or flexible pad (located between the airbag 222 and the user's wrist to play a buffering role) required for the airbag 222, and avoiding the problem of odor (sweat) in the airbag 222 due to the flexible sleeve or flexible pad not being cleaned in time. In addition, by using the groove 2202 to accommodate the airbag 222, the overall thickness of the airbag assembly 220 can also be reduced, which is conducive to the lightweight design of the airbag assembly 220.

[0055] Furthermore, in order to achieve the communication between the airbag 222 and the main body 100, the airbag assembly 220 may further include: a connector 223. Figures 7 and 8 As shown, the connector 223 can be embedded in the other end of the second tether 221, that is, the end that does not pass through the limiting space 2101, and when the other end of the second tether 221 is connected to the main body 100 from the first side 1031, the connector 223 can be synchronously connected to the air hole of the main body 100, such as being inserted into the air hole or inserted by the connecting structure constituting the air hole. At the same time, the connector 223 can also be convexly arranged in the groove 2202 and connected to one end of the air bag 222, and the connector 223 also has an air path connecting the air hole and the air bag 222, so that the main body 100 can be connected to the air bag 222 to control the expansion or contraction of the air bag 222.

[0056] Optionally, in order to facilitate the cleaning of the airbag assembly 220, the airbag 222 can also be detachably arranged in the groove 2202. Among them, the airbag assembly 220 can also include: an air nozzle connected to the airbag 222, and the air nozzle can be plugged into the partial area of ​​the connector 223 protruding from the groove 2202 to connect the connector 223 and the airbag 222. At the same time, the air nozzle and the connector 223 can also be embedded with magnets to fix them by magnetic attraction after the two are plugged and connected. When the user needs to remove the airbag 222, the user can overcome the magnetic force to pull the air nozzle off the connector 223 to remove the airbag 222 from the groove 2202. Of course, in addition to the magnetic attraction method, the air nozzle and the connector 223 can also be detachably connected in other ways, which are not listed one by one in this embodiment.

[0057] Optionally, in order to improve the installation firmness of the airbag 222 in the groove 2202, a limiting column 224 may be provided at the other end of the airbag 222, that is, at the end of the airbag 222 passing through the limiting space 2101, and a limiting groove 2203 for inserting the limiting column 224 may be provided on the bottom wall of the groove 2202. The limiting column 224 may be inserted into the limiting groove 2203 and may be engaged with the second tether 221 in the direction of exiting the limiting groove 2203. For example, the end size of the limiting column 224 may be larger than the size of the limiting groove 2203, so that after the limiting column 224 is inserted into the limiting groove 2203, it can force the second tether 221 to deform and engage with the side wall of the limiting groove 2203 in the direction of exiting the limiting groove 2203, thereby realizing the fixed connection between the other end of the airbag 222 and the second tether 221. At the same time, in order to avoid restraining the expansion of the airbag 222, when the airbag 222 expands, the limiting column 224 can also slide in the limiting groove 2203 as the airbag 222 expands, so as to prevent the limiting column 224 from pulling the airbag 222, thereby improving the expansion effect of the airbag 222. In this embodiment, the limiting groove 2203 may pass through the second tether 221, or may not pass through the second tether 221, and this is not limited in this embodiment.

[0058] Optionally, considering that the two ends of the airbag 222 are fixed by the connector 223 and the limiting column 224 respectively, the middle part of the airbag 222 between the two ends can also be fixed on the bottom wall of the groove 2202 to improve the firmness of the airbag 222 installed in the groove 2202. For example, Velcro can be provided on the bottom wall of the groove 2202, and Velcro is also provided on the middle part of the airbag 220 between the two ends, so that the middle part of the airbag 220 can be detachably bonded to the bottom wall of the groove 2202 through the Velcro.

[0059] The strap mechanism 200 provided in the present application is provided with a connection buckle 211 connected to the end of the first strap 212 to enclose and form a limited space 2101, and the airbag assembly 220 can pass through the limited space 2101 and overlap the first strap 212, so that the first strap 212 can be connected to the airbag assembly 220 through the connection buckle 211. At the same time, by opening a notch 2102 in communication with the limited space 2101 on the connection buckle 211, and the notch 2102 is also located on the side of the airbag assembly 220 away from the first strap 212, the notch 2102 can avoid the expansion of the airbag assembly 220 in the direction away from the first strap 212, so as to avoid the connection buckle 211 from restricting the expansion of the airbag assembly 220. In this way, not only can the connection buckle 211 be used to realize the connection between the first strap 212 and the airbag assembly 220, but also the connection buckle 211 can avoid restricting the expansion of the airbag assembly 220.

[0060] The above descriptions are only some embodiments of the present application, and do not limit the protection scope of the present application. Any equivalent device or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
