[0020] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be specifically noted that the following embodiments are only used to illustrate the present application, but do not limit the scope of the present application. Similarly, the following embodiments are only partial embodiments of the present application rather than all embodiments.

[0021] Referring to "embodiment" in the present application means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present application. The phrase appears in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0022] Please refer to Figures 1 to 3 , Figure 1 which is a structural schematic diagram of the wearable device 10 provided by an embodiment of the present application, Figure 2 Is Figure 1 a structural schematic diagram of the main body mechanism 100 in [diagram name], Figure 3 Is Figure 2 a structural schematic diagram of the locking assembly 110 in [diagram name].

[0023] The wearable device 10 provided in this application can be a smart watch, a smart bracelet, or a cuff-type blood pressure measurement device, etc. Hereinafter, only the case where the wearable device 10 is a smart watch will be taken as an example for illustration. As Figure 1 shown, the wearable device 10 may include: a main body mechanism 100 and a strap mechanism 200. Among them, the main body mechanism 100 is connected to the strap mechanism 200 and can jointly enclose a wearing space with the strap mechanism 200, and the user can wear the wearable device 10 on the wrist through the wearing space. At the same time, the main body mechanism 100 can also inflate and deflate the strap mechanism 200, so that the strap mechanism 200 can expand or contract under the control of the main body mechanism 100 to cooperate with the main body mechanism 100 to realize the function of blood measurement. In addition, in order to facilitate the user to replace or repair the main body mechanism 100 and the strap mechanism 200, the main body mechanism 100 can also be detachably connected to the strap mechanism 200. In this embodiment, when the main body mechanism 100 is detachably connected to the strap mechanism 200, the main body mechanism 100 can also be synchronously communicated with the strap mechanism 200, so as to use the structure of the detachable connection between the main body mechanism 100 and the strap mechanism 200 to maintain the communication between the two, so that the main body mechanism 100 can omit the structure for fixing the strap mechanism 200, thereby improving the space utilization rate of the main body mechanism 100.

[0024] The main body mechanism 100 is detachably connected to the strap mechanism 200 and can be communicated with the strap mechanism 200, and the main body mechanism 100 can inflate and deflate the strap mechanism 200 to cooperate with the strap mechanism 200 to measure the blood pressure of the user. As Figures 2 to 3 shown, the main body mechanism 100 has a top surface 101, a bottom surface 102, and a side surface 103. Among them, the top surface 101 and the bottom surface 102 are arranged opposite to each other, the side surface 103 is respectively connected to the top surface 101 and the bottom surface 102, and the strap mechanism 200 can be inserted into the main body mechanism 100 from a direction perpendicular to the side surface 103 and is detachably connected to the main body mechanism 100. At the same time, when the strap mechanism 200 is inserted into the main body mechanism 100, the strap mechanism 200 can also be synchronously communicated with the main body mechanism 100, so that the main body mechanism 100 can inflate and deflate the strap mechanism 200. In this embodiment, when the wearable device 10 is a smart watch, the main body mechanism 100 can specifically be a watch head, and the main body mechanism 100 includes: a housing and functional devices arranged on the housing, such as a display screen, an air pump, a camera, a battery, and various sensors, etc., so that the main body mechanism 100 can realize corresponding functions.

[0025] Exemplarily, a locking component 110 may be provided on the main body mechanism 100. When the strap mechanism 200 is inserted into the main body mechanism 100, the locking component 110 may be engaged with the strap mechanism 200 in a direction perpendicular to the side surface 103 to fix the strap mechanism 200 to the main body mechanism 100. At the same time, the locking component 110 is also slidably connected to the main body mechanism 100 and exposed on the bottom surface 102 of the main body mechanism 100. The locking component 110 can slide into the main body mechanism 100 under the pressing of the user to release the engagement state with the strap mechanism 200, so that the strap mechanism 200 can be withdrawn from the main body mechanism 100, thereby realizing the detachable connection between the main body mechanism 100 and the strap mechanism 200. In addition, when the strap mechanism 200 is engaged with the locking component 110 in place, the strap mechanism 200 can also be connected to the main body mechanism 100 in place synchronously. Or, before the strap mechanism 200 is engaged with the locking component 110 in place, the strap mechanism 200 can be connected to the main body mechanism 100 in place to avoid the situation that the strap mechanism 200 and the main body mechanism 100 are not yet completely connected after the strap mechanism 200 is engaged with the locking component 110 in place.

[0026] For example, the main body mechanism 100 is provided with a slot 104 on the side surface 103 for inserting the strap mechanism 200. The locking component 110 is inserted into the main body mechanism 100 from the bottom surface 102, and a part of the locking component 110 is located in the slot 104, so that when the strap mechanism 200 is inserted into the slot 104, the locking component 110 can cooperate with the strap mechanism 200 for detachable connection. Among them, the locking component 110 may include: a sliding member 111 and an elastic member 112. Among them, the sliding member 111 can be inserted into the main body mechanism 100 from the bottom surface 102 and is slidably connected to the main body mechanism 100, and the sliding member 111 can slide in a direction close to or away from the top surface 101. At the same time, a part of the sliding member 111 is also exposed in the slot 104 and located on the displacement path of the strap mechanism 200, so that the sliding member 111 can cooperate with the strap mechanism 200 inserted into the slot 104. The elastic member 112 is arranged in the main body mechanism 100 and located on the sliding path of the sliding member 111. When the sliding member 111 slides in a direction close to the top surface 101, the elastic member 112 can be elastically deformed under the pressing of the sliding member 111 and the main body mechanism 100 to provide an elastic force to drive the sliding member 111 to reset.

[0027] When the user needs to assemble the main body mechanism 100 and the strap mechanism 200, the user can insert the strap mechanism 200 into the slot 104, and the slider 111 can be pushed by the strap mechanism 200 to slide in the direction close to the top surface 101 to avoid the insertion of the strap mechanism 200. After the strap mechanism 200 is inserted in place, the slider 111 can be reset under the elastic action of the elastic member 112 to be engaged with the strap mechanism 200, so as to fix the strap mechanism 200 in the slot 104. When the user needs to disassemble the main body mechanism 100 and the strap mechanism 200, the user can press the slider 111 exposed on the bottom surface 102 and drive the slider 111 to slide in the direction close to the top surface 101 to release the engagement state with the strap mechanism 200, so as to remove the strap mechanism 200 from the slot 104. With such a setting, the detachable connection between the main body mechanism 100 and the strap mechanism 200 can be realized.

[0028] Optionally, in order to improve the stability of the detachable connection between the main body mechanism 100 and the strap mechanism 200, the number of the slots 104 can be two, and two parts of the slider 111 can be respectively exposed in the two slots 104 to cooperate with the strap mechanism 200 respectively. In addition, it can be understood that the foregoing solution for the detachable connection between the main body mechanism 100 and the strap mechanism 200 is only an exemplary illustration, and there can be various solutions for the main body mechanism 100 and the strap mechanism 200 to achieve detachable connection, such as achieving detachable connection by means of spring bars, etc. This embodiment does not limit this.

[0029] Furthermore, the main body mechanism 100 can also be provided with an air hole 105 on the side surface 103 for the strap mechanism 200 to insert, and the air hole 105 can communicate the strap mechanism 200 and the air pump in the main body mechanism 100, so that the main body mechanism 100 can inflate and deflate the strap mechanism 200 to control the expansion or contraction of the strap mechanism 200. As Figure 2 shown, the air hole 105 can be arranged adjacent to the slot 104, so that when the strap mechanism 200 is inserted into the slot 104, it can also be inserted into the air hole 105 to synchronously realize the detachable connection and communication between the main body mechanism 100 and the strap mechanism 200. At the same time, when the strap mechanism 200 is engaged with the slider 111 in place, the strap mechanism 200 can also be inserted into the air hole 105 in place synchronously. Or, before the strap mechanism 200 is engaged with the slider 111 in place, the strap mechanism 200 can be inserted into the air hole 105 in place to avoid the situation that after the strap mechanism 200 is engaged with the locking assembly 110 in place, the strap mechanism 200 and the main body mechanism 100 are not yet completely connected.

[0030] Optionally, in order to improve the inflation and deflation efficiency of the main body mechanism 100, or to enable the main body mechanism 100 to inflate and deflate two independent spaces on the strap mechanism 200 respectively, two air holes 105 may be opened on the side surface 103 of the main body mechanism 100. As Figure 2 shown, the two air holes 105 are both arranged adjacent to the slot 104, and the slot 104 may be located between the two air holes 105. At the same time, when the strap mechanism 200 is inserted into the slot 104, the strap mechanism 200 may also be synchronously inserted into the two air holes 105, and the main body mechanism 100 may inflate and deflate the strap mechanism 200 through the two air holes 105 to control the expansion or contraction of the strap mechanism 200.

[0031] Optionally, in addition to opening the air holes 105 for the insertion of the strap mechanism 200, the main body mechanism 100 may also be inserted into the strap mechanism 200 to achieve the connection between the main body mechanism 100 and the strap mechanism 200. For example, the main body mechanism 100 may be provided with an insertion tube communicated with an air pump on the side surface 103, the strap mechanism 200 may be provided with a corresponding insertion hole, and when the strap mechanism 200 is inserted into the slot 104 and engaged with the sliding member 111, the insertion tube on the main body mechanism 100 may be synchronously inserted into the insertion hole on the strap mechanism 200 to achieve the connection between the main body mechanism 100 and the strap mechanism 200.

[0032] Optionally, in addition to being detachably connected to the strap mechanism 200, the main body mechanism 100 and the strap mechanism 200 may also be non-detachably connected, and only when the main body mechanism 100 and the strap mechanism 200 are non-detachably connected, the main body mechanism 100 and the strap mechanism 200 can be synchronously connected.

[0033] Please refer to Figures 4 to 7 , Figure 4 is Figure 1 the schematic structural diagram of the strap mechanism 200 in Figure 5 is Figure 4 the exploded structural diagram of the strap mechanism 200 in Figure 6 is Figure 1 the partial cross-sectional structural diagram of the main body mechanism 100 and the strap assembly 210 along V-V in Figure 7 is Figure 5 the partial enlarged schematic diagram at A in Figure 8 is Figure 1 the partial cross-sectional structural diagram of the main body mechanism 100 and the strap assembly 210 along VI-VI in

[0034] The strap mechanism 200 is detachably connected to the main body mechanism 100, and can be connected to the main body mechanism 100, and the main body mechanism 100 can inflate and deflate the strap mechanism 200 to control the expansion or contraction of the strap mechanism 200. As Figures 4 to 5As shown, the strap mechanism 200 may include: a strap assembly 210 and an airbag assembly 220. Among them, the strap assembly 210 may be inserted into the slot 104 and detachably connected to the main body mechanism 100, and the strap assembly 210 may also jointly enclose the aforementioned wearing space with the main body mechanism 100. The airbag assembly 220 is disposed on one side of the strap assembly 210 within the wearing space, that is, the airbag assembly 220 can be arranged to contact the user's wrist, and the strap assembly 210 also has an air passage 230 that respectively communicates with the airbag assembly 220 and the main body mechanism 100, so that the main body mechanism 100 can inflate and deflate the airbag assembly 220 to control the expansion or contraction of the airbag assembly 220. In this embodiment, the strap assembly 210 and the airbag assembly 220 have the advantages of high connection strength and reliability, which is beneficial to reducing the probability of the strap assembly 210 and the airbag assembly 220 being pulled off, so as to ensure that the main body mechanism 100 can effectively inflate and deflate the airbag assembly 220.

[0035] Exemplarily, the strap assembly 210 may include: a connection head 212 and a strap 213. Among them, the connection head 212 may be embedded in the end of the strap 213, and a part of the connection head 212 also protrudes from the strap 213 and can be inserted into the slot 104 to be detachably connected to the main body mechanism 100. At the same time, the connection head 212 has the aforementioned air passage 230, and this air passage 230 can be synchronously inserted into the air hole 105 when the connection head 212 is inserted into the slot 104, and communicates with the air pump in the airbag assembly 220 and the main body mechanism 100, so that the main body mechanism 100 can inflate and deflate the airbag assembly 220 through the air hole 105 and the air passage 230. The strap 213 can jointly enclose the aforementioned wearing space with the main body mechanism 100, and the airbag assembly 220 can be connected to one side of the strap 213 within the wearing space, so as to facilitate the airbag assembly 220 to compress the blood vessels in the user's wrist when inflated. In this embodiment, when the wearable device 10 is a smart watch, the connection head 212 may specifically be a watch head grain, and the strap 213 may be a watch band.

[0036] Such as Figures 6 to 7As shown, the connector 212 may include: a main body portion 2121, a conduction portion 2122, a protruding portion 2123, a buckle portion 2124, and a mating portion 2125. Among them, the main body portion 2121 may be embedded in the end of the strap 213 to improve the connection firmness between the connector 212 and the strap 213. The conduction portion 2122 is connected to the main body portion 2121 and protrudes outside the strap 213, and one end of the conduction portion 2122 away from the main body portion 2121 can also be inserted into the air hole 105. The protruding portion 2123 is connected to the main body portion 2121 and passes through the strap 213. When the strap 213 and the main body mechanism 100 cooperate to enclose a wearing space, the protruding portion 2123 can also be exposed on the side of the strap 213 facing the wearing space to communicate with the airbag assembly 220. The buckle portion 2124 is connected to the side of the main body portion 2121 where the conduction portion 2122 is provided and protrudes from the end of the strap 213, and the buckle portion 2124 can also be inserted into the slot 104 to be detachably connected to the main body mechanism 100. The mating portion 2125 is connected to the main body portion 2121 and passes through the strap 213. When the strap 213 and the main body mechanism 100 cooperate to enclose a wearing space, the protruding portion 2123 can also be exposed on the side of the strap 213 facing the wearing space to be connected to the airbag assembly 220. In this embodiment, the insertion direction of the conduction portion 2122 is parallel to the insertion direction of the buckle portion 2124, and when the buckle portion 2124 is inserted into the slot 104 in place, the conduction portion 2122 can also be inserted into the air hole 105 in place.

[0037] Further, the main body portion 2121, the conduction portion 2122, and the protruding portion 2123 may jointly form the aforementioned air passage 230, so that the air passage 230 can communicate the airbag assembly 220 and the main body mechanism 100. As Figures 6 to 7As shown, the main body portion 2121 may include: a first side 2121a, a second side 2121b, and a third side 2121c. Among them, the first side 2121a is connected with a buckle portion 2124 and a conduction portion 2122. And after the buckle portion 2124 is detachably connected to the main body mechanism 100, the first side 2121a can also be attached to the side surface 103 of the main body mechanism 100 to improve the connection tightness between the strap mechanism 200 and the main body mechanism 100. The second side 2121b and the third side 2121c are both connected to and arranged opposite to the first side 2121a. And the second side 2121b is also close to the wearing space and is connected with a protruding portion 2123 and a matching portion 2125, so that after the protruding portion 2123 and the matching portion 2125 are passed through the strap 213, they can be exposed on the side of the strap 213 facing the wearing space. The terms "first", "second", and "third" in this application are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second", and "third" may explicitly or implicitly include at least one of such features.

[0038] The main body portion 2121 also has a gas guiding space 231, and the inner wall of the gas guiding space 231 can be used to jointly form the aforementioned air duct 230 with the conduction portion 2122 and the protruding portion 2123. As Figure 6 shown, the gas guiding space 231 can communicate with the conduction portion 2122 and the protruding portion 2123 respectively, and the gas guiding space 231 also forms an opening 2311 on the third side 2121c. Among them, the opening 2311 is left after a workpiece processes the main body portion 2121 from the third side 2121c to form the gas guiding space 231. Therefore, the strap assembly 210 can also be provided with a sealing cover 214 that covers the third side 2121c and seals the opening 2311. In addition, a receiving groove can also be formed on the third side 2121c, and the opening 2311 can be formed on the bottom wall of the receiving groove, while the sealing cover 214 can be arranged in the receiving groove and cover the bottom wall of the receiving groove to seal the opening 2311. With such a setting, the receiving groove can be used to accommodate the sealing cover 214 to prevent the sealing cover 214 from forming a protrusion on the third side 2121c.

[0039] It can be understood that if the conduction part 2122 and the protruding part 2123 are connected by opening holes into the main body part 2121 in their extending directions, the holes opened by the two can only communicate at the intersection point in their extending directions, and the area of the main body part 2121 corresponding to the intersection point of the extending directions of the conduction part 2122 and the protruding part 2123 needs to be designed thick enough. Otherwise, the holes opened by the conduction part 2122 and the protruding part 2123 in their extending directions will directly penetrate through the main body part 2121, making it impossible for the conduction part 2122 and the protruding part 2123 to communicate within the main body part 2121. However, if the thickness of the main body part 2121 is increased, it will not only cause an increase in the weight of the connector 212, but also affect the thickness of the strap 213 (the main body part 2121 is embedded in the strap 213), which is not conducive to the overall thin and light design of the strap mechanism 200.

[0040] Based on this, in this embodiment, by opening an air guide space 231 on the third side 2121c to connect the conduction part 2122 and the protruding part 2123, the length of the holes opened by the conduction part 2122 and the protruding part 2123 in their extending directions can be shortened, so as to reduce the thickness that the main body part 2121 needs to be designed at the connection part of the conduction part 2122 and the protruding part 2123 (equivalent to the air guide space 231). At the same time, the design of the air guide space 231 is also beneficial to the subsequent processing of the shape of the air duct 230 from the opening 2311. For example, the wall surface at the connection part of the air guide space 231 and the conduction part 2122 (the corner of the air duct 230) can be polished from the opening 2311 to polish the sharp edge surface into an arc surface, thereby improving the air guiding efficiency of the air duct 230.

[0041] Optionally, the design of the sealing cover 214 can also be omitted. At this time, in order to form the aforementioned air guide space 231 without increasing the thickness of the main body part 2121, the main body part 2121 can also be disassembled and designed into two independent structural parts, and the two independent structural parts can form a complete main body part 2121 after splicing and can jointly enclose to form the air guide space 231 after splicing, thereby omitting the design of forming the opening 2311 on the third side 2121c of the air guide space 231. At the same time, in order to improve the sealing performance of the air guide space 231, glue can also be applied to the gap between the two spliced structural parts or other airtight substances can be filled.

[0042] The conduction part 2122 is connected to the first side 2121a and protrudes from the end of the strap 213. When the buckle part 2124 is inserted into the slot 104, the conduction part 2122 can be synchronously inserted into the air hole 105 to connect the air hole 105 and the air guide space 231. As Figure 6As shown, the conduction part 2122 is provided with an air guide hole 232, and the air guide hole 232 can penetrate through the opposite sides of the conduction part 2122 in the extending direction of the conduction part 2122, that is, the direction in which the conduction part 2122 is inserted into or withdrawn from the air hole 105, and at the same time penetrate through the first side 2121a, so that the air guide hole 232 can communicate with the air hole 105 and the air guide space 231 respectively. In this embodiment, the inner walls of the air guide space 231 and the air guide hole 232 can be used to jointly form the aforementioned air passage 230 with the protruding part 2123.

[0043] Optionally, in order to reduce the probability of air leakage at the connection between the conduction part 2122 and the main body mechanism 100, the strap assembly 210 can also be provided with a sealing ring 215 sleeved on the conduction part 2122. As Figure 6 shown, when the conduction part 2122 is inserted into the air hole 105, the sealing ring 215 can be respectively abutted against the side walls of the conduction part 2122 and the air hole 105 to fill the gap between the side walls of the conduction part 2122 and the air hole 105, thereby reducing the probability of air leakage at the connection between the conduction part 2122 and the main body mechanism 100. In this embodiment, the sealing ring 215 can also be made of elastic materials such as silica gel, rubber and soft plastic, so that the sealing ring 215 can be respectively abutted against the conduction part 2122 and the main body mechanism 100.

[0044] The protruding part 2123 is connected to the second side 2121b and is arranged through the strap 213, and the protruding part 2123 is also exposed on the side of the strap 213 close to the wearing space. Among them, the protruding part 2123 is provided with a receiving hole 233, and the receiving hole 233 can penetrate through the opposite sides of the protruding part 2123 in the extending direction of the protruding part 2123, that is, the direction in which the second side 2121b approaches or moves away from the third side 2121c, and at the same time penetrate through the second side 2121b, so that the receiving hole 233 can communicate with the air guide space 231 and the wearing space respectively. In this embodiment, the inner walls of the air guide space 231, the air guide hole 232 and the receiving hole 233 can jointly form the aforementioned air passage 230, and the receiving hole 233 can also be inserted into the airbag assembly 220 to realize the connection between the airbag assembly 220 and the air passage 230.

[0045] Optionally, when the number of the air holes 105 is two, the number of the air channels 230 can also be two, so as to be respectively communicated with the two air holes 105. Among them, two independent air guiding spaces 231 can be provided on the main body portion 2121, the number of the conduction portions 2122 can also be two, and the two conduction portions 2122 are respectively communicated with the two air guiding spaces 231, and the two conduction portions 2122 are respectively used for inserting into the main body mechanism 100. The number of the protruding portions 2123 can also be two, and the two protruding portions 2123 are respectively communicated with the two air guiding spaces 231. The number of the sealing covers 214 can also be two, and the two sealing covers 214 are respectively used for blocking two openings 2311 formed by the two air guiding spaces 231 on the third side 2121c. It can be understood that the cooperation relationship between a single air guiding space 231 and the conduction portion 2122, the protruding portion 2123, and the sealing cover 214 can refer to the foregoing embodiments, and will not be elaborated herein.

[0046] It can be understood that the foregoing specific structure of the connecting head 212 and the formation of the air channel 230 are only exemplary descriptions. In some embodiments, the structure of the connecting head 212 and the formation of the air channel 230 can also be adaptively adjusted according to design requirements, as long as the connecting head 212 has the air channel 230 and can communicate the main body mechanism 100 and the airbag assembly 220. This embodiment does not make any limitations in this regard.

[0047] The buckle portion 2124 is connected to the first side 2121a and can be inserted into the slot 104 of the main body mechanism 100 to be detachably connected to the main body mechanism 100. As Figures 7 to 8 shown, the buckle portion 2124 is located between the two conduction portions 2122, and a card slot 21241 is provided in the region between the end of the buckle portion 2124 away from the first side 2121a and the end close to the first side 2121a. Among them, when the buckle portion 2124 is inserted into the slot 104, the end of the buckle portion 2124 away from the first side 2121a can push the sliding member 111 to slide in the direction close to the top surface 101 to avoid the insertion of the buckle portion 2124. When the buckle portion 2124 is inserted in place, the sliding member 111 can be reset into the card slot 21241 under the elastic force of the elastic member 112 and is clamped with the buckle portion 2124. Similarly, when the user presses the sliding member 111 to slide in the direction close to the top surface 101, the sliding member 111 can exit the card slot 21241 to release the clamping state with the buckle portion 2124, so that the buckle portion 2124 can exit from the slot 104, thereby realizing the detachable connection between the connecting head 212 and the main body mechanism 100. In this embodiment, when the number of the slots 104 is two, the number of the buckle portions 2124 is also two, and the two buckle portions 2124 can be respectively inserted into the two slots 104 to respectively cooperate with the sliding member 111, so as to improve the stability of the detachable connection between the connecting head 212 and the main body mechanism 100.

[0048] The mating part 2125 is connected to the second side 2121b, is disposed through the strap 213, and the mating part 2125 is also exposed on one side of the strap 213 close to the wearing space. As Figure 7 shown, the mating part 2125 is adjacently disposed to the protruding part 2123, and the mating part 2125 can be used to connect with the airbag assembly 220 to fix the airbag assembly 220 to the connection head 212. For example, a jack 21251 for inserting the airbag assembly 220 can be opened on one side of the mating part 2125 exposed in the wearing space, and threads are provided on the inner wall of the jack 21251 and can be threadedly connected with the airbag assembly 220, so that the airbag assembly 220 can be threadedly and tightly fitted to the connection head 212 to improve the connection firmness between the airbag assembly 220 and the strap assembly 210, thereby reducing the probability that the airbag assembly 220 is pulled out of the accommodation hole 233. In this embodiment, the number of the mating parts 2125 can be two, and the airbag assemblies 220 can be respectively inserted into the jacks 21251 of the two mating parts 2125 and are respectively threadedly fitted with the two mating parts 2125 to further improve the connection firmness between the airbag assembly 220 and the strap assembly 210.

[0049] Optionally, the design of the mating part 2125 can also be omitted. At this time, the main body part 2121 can be provided with the aforementioned jack 21251 on the second side 2121b, and the corresponding avoidance hole can be opened in the area of the strap 213 corresponding to the jack 21251. With such a setting, the airbag assembly 220 can still be inserted into the jack 21251 on the main body part 2121 through the avoidance hole of the strap 213 to be threadedly fitted with the main body part 2121, so as to be fixed on the connection head 212.

[0050] Please refer to Figures 9 to 12 , Figure 9 is Figure 4 a partial structural schematic diagram of the airbag assembly 220 in Figure 10 is Figure 9 a partial structural schematic diagram of the airbag assembly 220 in another perspective in Figure 11 is Figure 4 a partial cross-sectional structural schematic diagram of the strap mechanism 200 along Ⅳ-Ⅳ in Figure 12 is Figure 4 a partial cross-sectional structural schematic diagram of the airbag assembly 220 along Ⅶ-Ⅶ in

[0051] The airbag assembly 220 is connected to one side of the strap 213 close to the wearing space, is inserted into the jack 21251 and is threadedly fitted with the connection head 212, and the airbag assembly 220 is also inserted into the accommodation hole 233 and is connected to the air passage 230. As Figures 9 to 11As shown, the airbag assembly 220 may include: a first air nozzle 221, a first airbag 222, a rigid member 223, and a fastener 224. Among them, the first air nozzle 221 is connected to the end of the first airbag 222 in the thickness direction of the first airbag 222, and is in communication with the inside of the first airbag 222. One end of the first air nozzle 221 away from the first airbag 222 can also be inserted into the receiving hole 233 to communicate the air passage 230 and the first airbag 222. The first airbag 222 is connected to the side of the strap 213 close to the wearing space, and the first airbag 222 can expand or contract under the control of the main body mechanism 100 and cooperate with the main body mechanism 100 to realize the function of blood pressure measurement. The rigid member 223 is connected to the first air nozzle 221 and is on the same side of the first airbag 222 as the first air nozzle 221. The fastener 224 passes through the first airbag 222 and the rigid member 223 from the side of the first airbag 222 facing away from the rigid member 223, and can be inserted into the insertion hole 21251 after passing through the rigid member 223 to fasten the rigid member 223 to the connection head 212. In this embodiment, by setting the rigid member 223 to be connected to the first air nozzle 221, and the rigid member 223 can also be fixed to the connection head 212 through the fastener 224, the fastener 224 can ensure the firmness of the connection between the first air nozzle 221 and the air passage 230, so as to reduce the probability of the first air nozzle 221 being pulled out of the receiving hole 233 by the first airbag 222.

[0052] Exemplarily, the first air nozzle 221 is connected to the end of the first airbag 222, and is located between the first airbag 222 and the strap 213, and the first air nozzle 221 can be inserted into the receiving hole 233 to communicate the air passage 230 and the inside of the first airbag 222. Among them, the first air nozzle 221 can be made of TPU (Thermoplastic Urethane), and the first air nozzle 221 can be thermally pressed to the first airbag 222 to improve the sealing performance at the connection between the two. At the same time, the aforementioned sealing ring 215 can also be sleeved on the end of the first air nozzle 221 away from the first airbag 222. When the first air nozzle 221 is inserted into the receiving hole 233, the sealing ring 215 can abut against the inner wall of the receiving hole 233 and the first air nozzle 221 respectively to fill the gap between the inner wall of the receiving hole 233 and the first air nozzle 221, thereby improving the sealing performance of the connection between the first air nozzle 221 and the connection head 212. In this embodiment, two sealing rings 215 can be sleeved on the first air nozzle 221, and the deformation amounts generated by the two sealing rings 215 can be the same or different to further improve the sealing performance of the connection between the first air nozzle 221 and the connection head 212.

[0053] The first airbag 222 is connected to the side of the strap 213 close to the wearing space, and the first airbag 222 can expand or contract under the control of the main body mechanism 100. Among them, an avoidance groove 2221 is further formed on the side of the first airbag 222 facing away from the rigid member 223, and the avoidance groove 2221 can communicate with the rigid member 223 and is used to avoid the fastener 224, so that the fastener 224 can be passed through the rigid member 223 in the avoidance groove 2221. At the same time, the first airbag 222 and the strap 213 can be detachably connected by means such as buckles or Velcro, so that the first airbag 222 and the strap 213 can be replaced according to needs. Of course, in some embodiments, the first airbag 222 and the strap 213 can also be non-detachably connected, and this embodiment does not limit this.

[0054] Optionally, since the existence of the avoidance groove 2221 will cause the rigid member 223 and the fastener 224 to be exposed outside the first airbag 222, the airbag assembly 220 can further include a second airbag 225 for covering the avoidance groove 2221. As Figures 9 to 11 shown, the second airbag 225 is located on the side of the first airbag 222 facing away from the rigid member 223, and the shape of the second airbag 225 can match that of the first airbag 222, so that the second airbag 225 can cover the avoidance groove 2221 to prevent the rigid member 223 and the fastener 224 from being directly exposed to the external environment, thereby improving the appearance expressiveness of the airbag assembly 220. At the same time, in order to avoid the assembly of the fastener 224, the rigid member 223 and the connector 212, the end of the second airbag 225 covering the avoidance groove 2221 can also be movable relative to the first airbag 222, so that the end of the second airbag 225 covering the avoidance groove 2221 can be turned over relative to the first airbag 222, thereby exposing the avoidance groove 2221. In this embodiment, the area where the second airbag 225 does not cover the avoidance groove 2221 and is not movable can be connected to the first airbag 222 by hot pressing, so as to ensure the connection firmness of the first airbag 222 and the second airbag 225 while enabling the end of the second airbag 225 covering the avoidance groove 2221 to be movable.

[0055] Optionally, in order to prevent the end of the second airbag 225 covering the avoidance groove 2221 from being shaken unnecessarily under the influence of external force, a connecting portion 2252 protruding into the avoidance groove 2221 can be provided at one end of the second airbag 225 covering the avoidance groove 2221 ( Figure 11As shown by the dashed line in the figure. Among them, the material of the connecting part 2252 can be hard plastic, and the connecting part 2252 can also be fixed on the second airbag 225 by means such as hot pressing connection. At the same time, the connecting part 2252 can be detachably arranged in the avoidance groove 2221, so as to facilitate the user to turn over the second airbag 225 to assemble the fastener 224. For example, the connecting part 2252 can be in interference fit with the side wall of the avoidance groove 2221, that is, in interference fit with the first airbag 222, and can be disengaged from the avoidance groove 2221 when the user pulls the second airbag 225, so as to realize the detachable setting of the connecting part 2252. Or, a magnet can be embedded in the connecting part 2252, so that the connecting part 2252 can be adsorbed on the side of the rigid part 223 exposed in the avoidance groove 2221, and the user can also pull the second airbag 225 to overcome the magnetic force to disassemble the connecting part 2252, so as to realize the detachable setting of the connecting part 2252. Of course, in addition to the above two embodiments, there can be various detachable setting methods for the connecting part 2252, which are not elaborated one by one in this embodiment.

[0056] Optionally, in addition to covering the avoidance groove 2221 by the second airbag 225, the airbag assembly 220 can also be provided with an independent covering member to cover the avoidance groove 2221. For example, the covering member can be the same as or similar to the aforementioned connecting part 2252, and can be detachably arranged in the avoidance groove 2221. Of course, the structure of the covering member is not limited to this, and the covering member can also be a structure such as a covering cloth or a covering cover, which is not limited in this embodiment.

[0057] Optionally, when the strap assembly 210 and the airbag assembly 220 are non-detachably connected, one end of the second airbag 225 covering the avoidance groove 2221 can also be fixed on the first airbag 222 after the fastener 224 is installed, and cannot move relative to the first airbag 222. Similarly, the covering member can also be fixed in the avoidance groove 2221 after the fastener 224 is installed and cannot be disassembled from the avoidance groove 2221.

[0058] Exemplarily, in order to enable the main body mechanism 100 to independently inflate and deflate the first airbag 222 and the second airbag 225, the airbag assembly 220 can also be provided with a second air nozzle 226 communicated with the second airbag 225. Such as Figure 9 and Figure 11As shown, the second air nozzle 226 is connected to the end of the first air bag 222 in the thickness direction of the first air bag 222, and is located on the side of the first air bag 222 where the first air nozzle 221 is provided and is adjacent to the first air nozzle 221, and the second air nozzle 226 can be connected to the second air bag 225. At the same time, the first air nozzle 221 and the second air nozzle 226 can be inserted into the two receiving holes 233 respectively, so that the first air bag 222 can be connected to the main body 100 through the first air nozzle 221 and one air channel 230, and the second air bag 225 can be connected to the main body 100 through the second air nozzle 226 and another air channel 230. In this way, the main body 100 can independently inflate and deflate the first air bag 222 and the second air bag 225 through the first air nozzle 221 and the second air nozzle 226, so that the first air bag 222 and the second air bag 225 can be expanded or contracted simultaneously or successively.

[0059] Furthermore, since the second air nozzle 226 is located on the side of the first airbag 222 away from the second airbag 225, in order to achieve the communication between the second air nozzle 226 and the second airbag 225, the second airbag 225 can also be connected to a part of the space of the first airbag 222, so as to indirectly communicate with the second air nozzle 226 through the first airbag 222. For example, the first airbag 222 can have an independent first cavity 2222 and a second cavity 2223. Figures 11 to 12 As shown, the first cavity 2222 can be communicated with the first air nozzle 221, and the main body 100 can inflate the first cavity 2222 to expand the first airbag 222. The second cavity 2223 can be communicated with the second airbag 225 and the second air nozzle 226, respectively, so that the main body 100 can inflate the second airbag 225 through the second air nozzle 226 and the second cavity 2223, thereby realizing the independent control of the first airbag 222 and the second airbag 225 by the main body 100. In this embodiment, the membrane layer separating the first cavity 2222 and the second cavity 2223 can be a single layer or a double layer. That is, the cavity walls of the first cavity 2222 and the second cavity 2223 close to each other can share the same membrane layer, or can be composed of two membrane layers respectively.

[0060] Optionally, in addition to indirectly achieving the communication between the second air nozzle 226 and the second air bag 225 through the second cavity 2223, the second air nozzle 226 can also be directly connected to the second air bag 225. For example, the position of the first air bag 222 corresponding to the second air nozzle 226 can be provided with an avoidance position, and the second air nozzle 226 can be provided on the second air bag 225 through the avoidance position and communicate with the second air bag 225. The avoidance position can be formed by providing a notch or a through groove on the first air bag 222, and the avoidance groove 2221 can also be expanded to the position of the first air bag 222 corresponding to the second air nozzle 226 to form the aforementioned avoidance position.

[0061] Optionally, since the first airbag 222 and the second airbag 225 are connected by hot pressing, a sealed space 2201 is formed due to hot pressing between the immovable partial area of the second airbag 225 and the first airbag 222. As Figure 12 shown, the first airbag 222 may be provided with a first through hole 2224 communicating the second cavity 2223 and the sealed space 2201, and the second airbag 225 may be provided with a second through hole 2251 communicating the inside of the second airbag 225 and the sealed space 2201, so that the second cavity 2223 can communicate with the inside of the second airbag 225 through the first through hole 2224, the sealed space 2201 and the second through hole 2251. In this embodiment, in order to facilitate the communication between the second cavity 2223 and the second airbag 225, the second cavity 2223 is preferably arranged close to the second airbag 225.

[0062] Optionally, in some embodiments, when the first airbag 222 and the second airbag 225 are connected in other ways, the design of the sealed space 2201 can also be omitted. At this time, the first through hole 2224 and the second through hole 2251 can also be directly opened in the connecting area of the first airbag 222 and the second airbag 225 for communication, and this embodiment does not limit this.

[0063] Optionally, in some embodiments, the first airbag 222 and the second airbag 225 can also be completely connected, so that the main body mechanism 100 can simultaneously inflate and deflate the first airbag 222 and the second airbag 225 through the first air nozzle 221 to control the first airbag 222 and the second airbag 225 to expand or contract simultaneously.

[0064] Optionally, the aforementioned sealing ring 215 can also be sleeved on the second air nozzle 226, and the number of the sealing rings 215 can also be two to improve the sealing performance of the communication between the second air nozzle 226 and the connector 212.

[0065] The rigid member 223 is respectively connected to the first air nozzle 221 and the second air nozzle 226, and is located on the same side of the first airbag 222 as the first air nozzle 221 and the second air nozzle 226, that is, on the side of the first airbag 222 close to the strap 213. As Figure 11As shown, the rigid member 223 can be arranged in a sheet shape and have a certain length, and the opposite ends of the rigid member 223 can be respectively sleeved on the first nozzle 221 and the second nozzle 226. At the same time, the rigid member 223, the first nozzle 221 and the second nozzle 226 can be integrally formed by an injection molding process to improve the connection firmness between the rigid member 223, the first nozzle 221 and the second nozzle 226. In addition, the rigid member 223 can be arranged at an interval from the first airbag 222 to form a gap of 0.2-0.3 mm between the rigid member 223 and the first airbag 222, so as to prevent the rigid member 223 from pressing against the first airbag 222 when the first airbag 222 is thermally pressed and connected to the first nozzle 221 and the second nozzle 226 respectively, thereby causing the situation that the thermal pressing of the first airbag 222 to the first nozzle 221 and the second nozzle 226 is not in place. In this embodiment, the material of the rigid member 223 can be metal (such as steel, etc.), and the first nozzle 221, the second nozzle 226 and the rigid member 223 can be integrally formed by an insert injection molding process to improve the connection strength among the three.

[0066] Optionally, in some embodiments, the connection manner between the rigid member 223, the first nozzle 221 and the second nozzle 226 may not be limited to integrally forming by injection molding, and the two may also be fixedly connected by other methods such as welding, snap connection or interference fit. Similarly, the rigid member 223 can also be made of other materials with a certain structural strength, and is not limited to metal.

[0067] Optionally, in some embodiments, the first nozzle 221 and the second nozzle 226 can also be detachably arranged on the rigid member 223. For example, the rigid member 223 can be disassembled and designed into two layers of steel plates, and skirt structures can be arranged on the circumferences of the first nozzle 221 and the second nozzle 226. Among them, the first nozzle 221 and the second nozzle 226 can be arranged through the two layers of steel plates, and the above skirt structures can be clamped by the two layers of steel plates, and the two layers of steel plates can be locked by screws to fix the first nozzle 221 and the second nozzle 226 on the rigid member 223. In this way, the user can complete the disassembly among the first nozzle 221, the second nozzle 226 and the rigid member 223 by unscrewing the screws. In this embodiment, an avoidance notch for the skirt structure can be arranged on one of the two layers of steel plates to avoid the skirt structure when the first nozzle 221 and the second nozzle 226 pass through the steel plates. After the skirt structure passes through the notch, the assembler can rotate the first nozzle 221 and the second nozzle 226 so that the skirt structure is misaligned with the notch to be clamped by the two layers of steel plates.

[0068] The fastener 224 is inserted through the rigid member 223 from within the avoidance groove 2221, and can be inserted into the insertion hole 21251 after passing through the rigid member 223. Moreover, the fastener 224 can also be threadedly connected to the inner wall of the insertion hole 21251 to lock the rigid member 223 to the connector 212, thereby improving the connection firmness and reliability between the rigid member 223 and the connector 212. As Figure 12 shown, the fastener 224 can specifically be a bolt or a screw. When assembling the airbag assembly 220 and the strap assembly 210, the user can turn up the end of the second airbag 225 that shields the avoidance groove 2221, and use tools such as a screwdriver to pass the fastener 224 through the rigid member 223 from within the avoidance groove 2221 and screw it into the insertion hole 21251, thereby realizing the fixed assembly of the rigid member 223 and the connector 212.

[0069] In this embodiment, by integrally forming the rigid member 223 with the first nozzle 221 and the second nozzle 226, and locking the rigid member 223 to the connector 212 through the fastener 224, it is beneficial to improve the tensile strength of the first nozzle 221 and the second nozzle 226, and through actual measurement, the maximum tensile force that can be withstand is 40 - 50 N. At the same time, by fixing the rigid member 223 through the fastener 224, it is beneficial to ensure strong connectivity reliability between the first nozzle 221 and the second nozzle 226 and the connector 212, and it is not likely to fail due to changes in the external environment or long-term use.

[0070] Optionally, the number of fasteners 224 can be two, which respectively cooperate with the two insertion holes 21251 on the connector 212, thereby further improving the connection stability between the rigid member 223 and the connector 212. Of course, in addition to the threaded fit, the fastener 224 can also be fixedly connected to the connector 212 in other ways. For example, the fastener 224 can also be put into the insertion hole 21251 after being calcined at high temperature to be welded with the mating part 2125. Or, the fastener 224 can be in interference fit with the mating part 2125.

[0071] Optionally, in addition to being connected to the main body mechanism 100 through the connector 212, the airbag assembly 220 can also be directly connected to the main body mechanism 100. For example, air holes 105 and insertion holes 21251 can be formed on the bottom surface 102 of the main body mechanism 100, and the first nozzle 221 and the second nozzle 226 can be inserted into the air holes 105 from the bottom surface 102 to realize the connection between the main body mechanism 100 and the first airbag 222 and the second airbag 225. Similarly, the fastener 224 can also be inserted through the rigid member 223 from the bottom surface 102 and inserted into the insertion hole 21251 to fasten the rigid member 223 to the main body mechanism 100.

[0072] The airbag assembly 220 provided by the present application is configured such that the first air nozzle 221 is connected to the end of the first airbag 222 in the thickness direction of the first airbag 222, and the rigid member 223 connected to the first air nozzle 221 is also on the same side of the first airbag 222 as the first air nozzle 221. Further, an avoidance groove 2221 is formed on the side of the first airbag 222 facing away from the rigid member 223. The fastener 224 can pass through the rigid member 223 from within the avoidance groove 2221. When the first air nozzle 221 is in communication with an external structure (equivalent to the connection head 212), the fastener 224 can also be inserted into the external structure synchronously and fix the rigid member 223 to the external structure. With such a configuration, the rigid member 223 and the fastener 224 can be used to achieve a fixed connection between the first air nozzle 221 and the external structure. Compared with the solution of using adhesive bonding, it is beneficial to improve the connection strength and reliability between the first air nozzle 221 and the external structure.
