Technical Field

[0001] The present application relates to the technical field of wearable devices, and in particular to a wearable device, a watch head mechanism, and a shell assembly. Background Art

[0002] At present, the common blood pressure measurement scheme of smart watches is to set an airbag on the watch strap and inflate the airbag through the watch head, so that the airbag can expand to compress and block the user's blood vessels for blood pressure measurement. Among them, the air nozzle of the airbag often needs to be set on the watch head to connect to the air pump in the watch head, so that the air pump can inflate the airbag through the air nozzle. At the same time, the watch head will also be provided with a limiting structure for fixing the air nozzle to improve the connection firmness between the air nozzle and the watch head. However, the limiting structure for fixing the air nozzle generally takes up additional space in the watch head, resulting in a reduction in the available space of the watch head, thereby limiting the design of the watch head and the layout of internal devices.

With such a configuration, the fixing structure required for maintaining the connection between the strap mechanism and the air path on the housing component of the watch header mechanism can be omitted, so as to increase the available space of the watch header mechanism, thereby reducing the restrictions on the design of the watch header mechanism and the layout of internal devices due to insufficient space.

[0033] 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.

[0034] 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.

[0035] See also Figure 1 to Figure 2 , Figure 1 is a partial structural diagram of a wearable device 10 provided in an embodiment of the present application, Figure 2 yes Figure 1 Schematic diagram of the structure of the middle strap mechanism 100.

[0036] The wearable device 10 provided in this application may be a smart watch, a smart bracelet, or a cuff-type blood pressure measuring device, etc., and the following is only an example of the wearable device 10 being a smart watch. Figure 1 As shown, the wearable device 10 includes: a strap mechanism 100 and a header mechanism 200. The strap mechanism 100 is detachably connected to the header mechanism 200, and can be used to cooperate with the header mechanism 200 to form a wearing space for the user to wear, and the strap mechanism 100 can also expand or contract under the control of the header mechanism 200 to cooperate with the header mechanism 200 to measure the user's blood pressure. The header mechanism 200 can be integrated with various functional devices required by the wearable device 10, and can be used to inflate and deflate the strap mechanism 100, so that the strap mechanism 100 can expand or contract under the control of the header mechanism 200. In this embodiment, when the strap mechanism 100 is detachably connected to the header mechanism 200, the strap mechanism 100 can also be synchronously connected to the header mechanism 200, so that the header mechanism 200 can omit the structure for fixing the inflation and deflation interface of the strap mechanism 100, so as to increase the available space of the header mechanism 200, thereby reducing the restrictions on the shape design and internal device layout of the header mechanism 200 due to insufficient space.

[0037] The strap mechanism 100 can be detachably connected to the watch head mechanism 200 and can expand or contract under the control of the watch head mechanism 200. Figure 2 As shown, the strap mechanism 100 includes: a strap assembly 110 and a connecting assembly 120. The strap assembly 110 is connected to the connecting assembly 120, and can be detachably connected to the header mechanism 200 through the connecting assembly 120, and the strap assembly 110 can also expand or contract under the control of the header mechanism 200 to cooperate with the header mechanism 200 to measure the user's blood pressure. The connecting assembly 120 is connected to the strap assembly 110, and the connecting assembly 120 can also be assembled on the header mechanism 200 and detachably connected to the header mechanism 200 to achieve a detachable connection between the strap assembly 110 and the header mechanism 200. At the same time, the connecting assembly 120 can also synchronously connect the strap assembly 110 and the header mechanism 200 when assembled with the header mechanism 200, so that the header mechanism 200 can inflate and deflate the strap assembly 110 through the connecting assembly 120 to achieve the expansion or contraction of the strap assembly 110.

[0038] The inventors have found that in addition to the structure for realizing detachable connection with the strap assembly 110, the watch header mechanism 200 in the related scheme is also provided with a structure for fixing the charging and discharging interface of the strap assembly 110. For example, the watch header mechanism 200 is provided with a groove for installing the charging and discharging interface, and is provided with a limit cover for fixing the charging and discharging interface in the groove. However, the structure independently provided for fixing the charging and discharging interface (such as the aforementioned limit cover) generally occupies more space of the watch header mechanism 200, resulting in a reduction in the available space of the watch header mechanism 200, thereby restricting the design of the watch header mechanism 200 and the layout of internal devices.

[0039] Based on this, the wearable device 10 provided in the embodiment of the present application solves the above technical problems by reusing the connection component 120. That is, the header mechanism 200 can not only be detachably connected to the strap component 110 through the connection component 120, but also can inflate and deflate the strap component 110 through the connection component 120. Compared with the solution in which the header mechanism 200 adopts two different structures to respectively realize the detachable connection and the fixed charging and deflation interface, the header mechanism 200 in this embodiment can omit the structure for fixing the charging and deflation interface of the strap component 110, so as to increase the available space of the header mechanism 200, thereby reducing the limitations on the shape design and internal device layout of the header mechanism 200 due to insufficient space.

[0040] 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.

[0041] Please combine Figure 2 See also Figures 3 to 5 , Figure 3 yes Figure 2 A schematic diagram of the connection structure between the middle strap 111 and the connection assembly 120, Figure 4 yes Figure 2 A schematic diagram of a portion of the structure of the middle airbag 112, Figure 5 yes Figure 1 Schematic diagram of the partial cross-sectional structure of the wearable device 10 along V-V.

[0042] The strap assembly 110 is connected to the connecting assembly 120 and can expand or contract under the control of the watch head mechanism 200. Figures 2 to 3As shown, the strap assembly 110 includes: a strap 111 and an airbag 112. The strap 111 is connected to the connecting assembly 120, and can be detachably connected to the header mechanism 200 through the connecting assembly 120, and the strap 111 can be used to cooperate with the header mechanism 200 to form a wearing space for the user to wear. The airbag 112 is arranged on the strap 111 and connected to the connecting assembly 120, and the airbag 112 is also connected to the connecting assembly 120, so that the header mechanism 200 can inflate and deflate the airbag 112 through the connecting assembly 120 to control the airbag 112 to expand or contract, thereby cooperating with the header mechanism 200 to measure the user's blood pressure. Of course, in addition to blood pressure measurement, the airbag 112 can also cooperate with the header mechanism 200 to achieve other measurement functions (such as heart rate measurement, etc.), which is not limited in this embodiment.

[0043] Exemplarily, the end of the strap 111 is connected to the connecting component 120, and the connecting component 120 is preferably embedded in the end of the strap 111, so as to enhance the connection firmness between the strap 111 and the connecting component 120, and at the same time, the strap 111 is used to shield the connecting component 120, thereby improving the appearance refinement of the strap mechanism 100. At the same time, part of the structure of the connecting component 120 can also be arranged protruding from the strap 111, so as to achieve a detachable connection with the header mechanism 200. In addition, the side of the strap 111 located in the wearing space can also be used to connect with the airbag 112, so that the airbag 112 fits the user's wrist, thereby cooperating with the header mechanism 200 to measure the user's blood pressure. For example, a connecting hole 1111 is provided on the side of the strap 111 located in the wearing space, and a connecting column 1121 ( Figure 4 ) to achieve a detachable connection between the strap 111 and the airbag 112 (the positions of the connection hole 1111 and the connection column 1121 can also be interchanged). Alternatively, a Velcro can be provided on one side of the strap 111 located in the wearing space, and the Velcro can be used to detachably connect to the airbag 112. In this embodiment, the material of the strap 111 can be TPU (Thermoplastic Urethane), knitted material or fluororubber. Of course, the material of the strap 111 is not limited to this, and this embodiment will not list them one by one here.

[0044] Optionally, in addition to being embedded in the end of the strap 111, the connecting component 120 can also be connected to the end of the strap 111 in other ways, as long as it can ensure that the strap 111 and the connecting component 120 have sufficient connection strength, and the connecting component 120 can cooperate with the watch head mechanism 200, which is not limited in this embodiment. At the same time, in addition to being detachably connected to the airbag 112, the strap 111 can also be fixedly connected to the airbag 112, so that the strap 111 and the airbag 112 are not detachable, and it only needs to ensure that the airbag 112 can be connected to the connecting component 120, which is not limited in this embodiment.

[0045] The airbag 112 is disposed on one side of the strap 111 located in the wearing space, and the airbag 112 is also connected to the connecting component 120 and communicates with the connecting component 120. Figures 4 to 5 As shown, the airbag 112 may include: an airbag body 1122 and an air nozzle 1123. The airbag body 1122 is disposed on the side of the watchband 111 located in the wearing space and connected to the watchband 111, and the aforementioned connecting column 1121 may be disposed on the side of the airbag body 1122 facing the watchband 111. The air nozzle 1123 is disposed at the end of the airbag body 1122 and is located on the side of the airbag body 1122 facing the watchband 111, and the air nozzle 1123 is also connected to the inside of the airbag body 1122. At the same time, the air nozzle 1123 may also be connected to the connecting component 120, and connect the airbag body 1122 and the connecting component 120, so that the watch head mechanism 200 can inflate and deflate the airbag body 1122 through the connecting component 120, thereby realizing the expansion or contraction of the airbag body 1122. In this embodiment, the air nozzle 1123 is preferably inserted into the connecting component 120 to communicate with the connecting component 120.

[0046] Optionally, in order to improve the air tightness of the airbag body 1122, the airbag body 1122 and the air nozzle 1123 can be fixed by heat pressing to improve the tightness of the airbag body 1122 and the air nozzle 1123. Of course, the airbag body 1122 and the air nozzle 1123 can also be connected in other ways, which is not limited in this embodiment.

[0047] Optionally, in order to reduce the probability of air leakage at the connection between the air nozzle 1123 and the connecting assembly 120, the airbag 112 may also be provided with a sealing ring 1124 arranged around the circumference of the air nozzle 1123, and when the air nozzle 1123 is inserted into the connecting assembly 120, the sealing ring 1124 may abut against the air nozzle 1123 and the connecting assembly 120 respectively to fill the gap between the air nozzle 1123 and the connecting assembly 120, thereby reducing the probability of air leakage at the connection between the air nozzle 1123 and the connecting assembly 120. In this embodiment, the sealing ring 1124 may be made of elastic materials such as silicone, rubber, and soft plastic, so that the sealing ring 1124 can abut against the air nozzle 1123 and the connecting assembly 120 respectively. Optionally, in addition to the sealing ring 1124, glue may also be applied at the connection between the air nozzle 1123 and the connecting assembly 120 for sealing.

[0048] Optionally, the number of the air nozzles 1123 can also be two, and the two air nozzles 1123 can be symmetrically arranged on the ends of the airbag body 1122, and are used to be inserted into the connecting assembly 120 to connect the airbag body 1122 and the header mechanism 200, so that the header mechanism 200 can inflate and deflate the airbag body 1122 through the two air nozzles 1123. Of course, in addition to the symmetrical arrangement, the two air nozzles 1123 can also be arranged according to design requirements, and it is sufficient that the two air nozzles 1123 can be inserted into the connecting assembly 120 to achieve the connection between the airbag body 1122 and the connecting assembly 120, and this embodiment is not limited to this.

[0049] Optionally, when there are two air nozzles 1123, the airbag body 1122 may have two independent cavities, and the two cavities may be respectively connected to the two air nozzles 1123. When the user wears the wearable device 10, one cavity may cover most of the user's wrist, so that after inflation, the airbag body 1122 may expand in a large range to tighten the user's wrist and compress the blood vessels, while the other cavity may cover the area where the radial artery in the user's wrist is located, so that after inflation, the airbag body 1122 may expand in a small range to fit the arterial area of ​​the user's wrist, thereby cooperating with the meter head mechanism 200 to measure the user's pulse pressure wave and other data, and finally realizing the blood pressure measurement function of the wearable device 10.

[0050] Optionally, in addition to the aforementioned airbag 112 structure, the specific structure of the airbag 112 can also be adaptively adjusted according to design requirements, which is not limited in this embodiment. For example, the design of the air nozzle 1123 can also be omitted, and a hard structure for the connecting component 120 to be inserted can be provided on the airbag body 1122 to achieve the connection between the airbag body 1122 and the connecting component 120. Alternatively, the airbag body 1122 itself can be directly inserted by the connecting component 120 to achieve the connection between the airbag body 1122 and the connecting component 120. Alternatively, the airbag body 1122 and the connecting component 120 are an integrated structure that is connected to each other to achieve the connection between the airbag body 1122 and the connecting component 120, which is not limited in this embodiment.

[0051] Optionally, the airbag 112 may not be limited to being arranged on the side of the strap 111 facing the wearing space. For example, the airbag 112 may only include the airbag body 1122, and the airbag body 1122 may be embedded in the strap 111 and communicate with the connecting assembly 120 in the strap 111. At the same time, considering the expansion problem of the airbag body 1122, the strap 111 is preferably made of a material that can be deformed as the airbag body 1122 expands, so as to reduce the restriction of the strap 111 on the expansion of the airbag body 1122. In this embodiment, the specific connection method between the airbag body 1122 and the connecting assembly 120 is the same or similar to that in the above embodiment, and will not be repeated here.

[0052] Please combine Figure 5 See also Figures 6 to 8 , Figure 6 yes Figure 2 A schematic diagram of the structure of the connecting component 120, Figure 7 yes Figure 6 A schematic diagram of the structure of the middle connector 121, Figure 8 yes Figure 6 A schematic structural diagram of the middle connector 121 from another perspective.

[0053] The connecting component 120 is connected to the end of the strap 111 and is detachably mounted on the watch head mechanism. The connecting component 120 also connects the airbag body 1122 and the watch head mechanism 200, so that the watch head mechanism 200 can inflate and deflate the airbag body 1122 through the connecting component 120. Figure 5As shown, the connection component 120 has an airway 1201, and when the connection component 120 is detachably connected to the header mechanism 200, the airway 1201 can synchronously connect the airbag body 1122 and the header mechanism 200, so that the header mechanism 200 can inflate and deflate the airbag body 1122 through the airway 1201 to achieve the expansion or contraction of the airbag body 1122. In this way, the connection component 120 can play a fixing role in the connection between the airway 1201 and the header mechanism 200 through the detachable connection with the header mechanism 200, so that the header mechanism 200 can omit the structure required for fixing the airway 1201, so as to increase the available space of the header mechanism 200, thereby reducing the restrictions on the shape design and internal device layout of the header mechanism 200 due to insufficient space. The structure of the connection component 120 is described in detail below.

[0054] like Figures 5 to 8 As shown, the connection assembly 120 includes: a connector 121 and a sealing cover 122. The connector 121 is also embedded in the end of the strap 111, and part of the structure of the connector 121 is also protruding from the strap 111, and can be inserted into the watch head mechanism 200 to be detachably connected to the watch head mechanism 200. At the same time, the connector 121 can also have the aforementioned airway 1201, and when the connector 121 is inserted into the watch head mechanism 200, part of the airway 1201 can also be inserted into the watch head mechanism 200 synchronously with the connector 121, and the insertion direction of the connector 121 is parallel to the insertion direction of the airway 1201. The sealing cover 122 is provided on the connector 121, and the sealing cover 122 is used to block the opening left on the connector 121 due to the processing of the airway 1201 to ensure the sealing of the airway 1201. In this embodiment, the connector 121 and the sealing cover 122 can be assembled and embedded in the end of the strap 111 through the process of in-mold injection molding, and the material of the connector 121 and the sealing cover 122 is preferably hard plastic, so as to provide a certain structural strength for the connection assembly 120 and help reduce the weight of the connection assembly 120. Of course, the connection method of the connector 121 and the strap 111, and the selected materials of the connector 121 and the sealing cover 122 can also be adjusted according to design requirements, and this embodiment does not limit this.

[0055] Optionally, in addition to the connector 121 being inserted into the meter header mechanism 200, the connector 121 may also be inserted into the meter header mechanism 200 to be detachably connected to the meter header mechanism 200. Similarly, in addition to the airway 1201 being inserted into the meter header mechanism 200, the airway 1201 may also be inserted into the meter header mechanism 200 to be connected to the meter header mechanism 200. The following description will only be made by taking the connector 121 being inserted into the meter header mechanism 200 and the airway 1201 being synchronously inserted into the meter header mechanism 200 with the connector 121 as an example.

[0056] It can be understood that the connector 121 can be inserted into the header mechanism 200 from the side of the header mechanism 200 . For example, the side of the header mechanism 200 can be provided with an opening for inserting part or all of the connector 121 .

[0057] Exemplarily, the connector 121 may be the head of the strap 111, and the connector 121 includes: a main body 1211, a conductive part 1212, a protruding part 1213, and a buckle part 1214. The main body 1211 may be embedded in the end of the strap 111 to achieve the connection between the connector 121 and the strap 111. The conductive part 1212 is connected to the main body 1211 and protrudes from the strap 111, and one end of the conductive part 1212 away from the main body 1211 can also be inserted into the watch head mechanism 200. The protruding part 1213 is connected to the main body 1211 and is inserted into the watch strap 111, and when the watch strap 111 and the watch head mechanism 200 are arranged to form a wearing space, the protruding part 1213 can also be exposed on the side of the watch strap 111 facing the wearing space for the air nozzle 1123 to be inserted. The buckle portion 1214 is connected to the side of the main body 1211 provided with the conducting portion 1212, and is arranged protruding from the end of the strap 111, and the buckle portion 1214 can also be inserted into the watch header mechanism 200 to be detachably connected to the watch header mechanism 200. In this embodiment, the conducting portion 1212 can be inserted into the watch header mechanism 200 simultaneously when the buckle portion 1214 is inserted into the watch header mechanism 200, and the insertion direction of the conducting portion 1212 is also parallel to the insertion direction of the buckle portion 1214, and the main body 1211, the conducting portion 1212, the protruding portion 1213 and the sealing cover 122 can jointly constitute the aforementioned airway 1201, so that the airway 1201 can connect the airbag body 1122 and the watch header mechanism 200.

[0058] The main body 1211 may include: a first side 1211a, a second side 1211b and a third side 1211c. The first side 1211a is used to connect the buckle portion 1214 and the conductive portion 1212, and when the buckle portion 1214 is detachably connected to the watch head mechanism 200, the first side 1211a can also be arranged opposite to the watch head mechanism 200. The second side 1211b and the third side 1211c are both connected to the first side 1211a and arranged opposite to each other. At the same time, the second side 1211b is also arranged close to the side of the strap 111 facing the wearing space, and is used to connect the protrusion 1213, so that the protrusion 1213 is exposed on the side of the strap 111 facing the wearing space. The third side 1211c can be used for processing the main body 1211 by a processing piece, and the third side 1211c can have an opening left over from processing to form the airway 1201. The sealing cover 122 is disposed on the third side 1211c to seal the opening left over from processing to form the airway 1201.

[0059] 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.

[0060] The main body 1211 also has an air guiding space 1201a, and the inner wall of the air guiding space 1201a can be used to form the aforementioned air channel 1201 together with the conducting portion 1212, the protruding portion 1213 and the sealing cover 122. Figure 5 and Figures 7 and 8 As shown, the air guide space 1201a can be connected to the conduction part 1212 on the first side 1211a, so as to be connected to the header mechanism 200 through the conduction part 1212. At the same time, the air guide space 1201a is also formed with a first opening 1202a and a second opening 1202b on the second side 1211b and the third side 1211c, respectively. Among them, the first opening 1202a can be connected to the protrusion 1213 on the second side 1211b, so that the air guide space 1201a can also be connected to the airbag body 1122 through the protrusion 1213 and the air nozzle 1123. The second opening 1202b is a processing part, so that the main body 1211 is processed on the third side 1211c to form the opening of the air guide space 1201a, and the sealing cover 122 can be arranged on the third side 1211c and block the second opening 1202b. Through the above arrangement, the inner wall of the air guide space 1201a can be used to form the aforementioned airway 1201 together with the conducting portion 1212, the protruding portion 1213 and the sealing cover 122 on one side located in the air guide space 1201a (hereinafter only the sealing cover 122 is omitted).

[0061] Optionally, the first opening 1202a may not be limited to being opened on the second side 1211b. For example, when the airbag body 1122 is previously disposed in the strap 111, the first opening 1202a may also be opened on the third side 1211c, and the connecting end of the airbag body 1122 may extend to the third side 1211c to communicate with the air guide space 1201a through the first opening 1202a. Of course, in addition to the third side 1211c, the first opening 1202a may also be opened on any outer side of the main body 1211, as long as the airbag body 1122 can communicate with the air guide space 1201a through the first opening 1202a, and this embodiment does not limit this.

[0062] It is understandable that if the conducting portion 1212 and the protruding portion 1213 are connected by opening holes in the main body 1211 in the direction of their extension, the holes opened by the two can only communicate at the intersection in the direction of their extension, and the area of ​​the main body 1211 corresponding to the intersection of the conducting portion 1212 and the protruding portion 1213 in the direction of their extension needs to have a sufficiently large thickness, otherwise the holes opened by the conducting portion 1212 and the protruding portion 1213 in the direction of their extension will directly penetrate the main body 1211 and cannot be connected in the main body 1211. The increase in the thickness of the main body 1211 will not only increase the weight of the connector 121, but also affect the thickness of the strap 111 (the main body 1211 is embedded in the strap 111), which is not conducive to the overall thin and light design of the strap mechanism 100.

[0063] Based on this, in this embodiment, by opening the air-guiding space 1201a from the third side 1211c to connect the conducting part 1212 and the protruding part 1213, the length of the hole opened in the extending direction of the conducting part 1212 and the protruding part 1213 can be shortened, so as to reduce the thickness of the main body 1211 at the connecting part 1212 and the protruding part 1213 (equivalent to the air-guiding space 1201a). At the same time, the design of the air-guiding space 1201a is also conducive to the subsequent processing of the shape of the airway 1201 from the second opening 1202b. For example, the wall surface of the connecting part of the air-guiding space 1201a and the conducting part 1212 (at the corner of the airway 1201) can be polished from the second opening 1202b to polish the sharp edge surface into a curved surface, thereby improving the air-guiding effect of the airway 1201.

[0064] Optionally, in order to prevent the sealing cover 122 from forming a bulge on the third side 1211c due to blocking the second opening 1202b, a receiving groove 1203 may be provided on the third side 1211c, and the second opening 1202b may be formed on the bottom wall of the receiving groove 1203. The sealing cover 122 may be arranged in the receiving groove 1203 and block the second opening 1202b, and the receiving groove 1203 may absorb the thickness of the sealing cover 122 to prevent the sealing cover 122 from forming a bulge on the third side 1211c. At the same time, the sealing cover 122 may be fixed in the receiving groove 1203 by dispensing or spot welding to improve the connection firmness and sealing of the sealing cover 122 and the main body 1211. In this embodiment, the shape of the sealing cover 122 may match the receiving groove 1203, and the size of the sealing cover 122 may be slightly smaller than the size of the receiving groove 1203, so as to install the sealing cover 122.

[0065] Optionally, the sealing cover 122 may be spaced apart from the side wall of the receiving groove 1203, so that there is a gap between the sealing cover 122 and the side wall of the receiving groove 1203. In this way, when the strap 111 and the connector 121 are subjected to the in-mold injection molding process, the strap 111 may also fill the gap between the sealing cover 122 and the side wall of the receiving groove 1203, so as to further improve the combination firmness of the strap 111, the connector 121 and the sealing cover 122.

[0066] Optionally, the design of the sealing cover 122 can also be omitted. At this time, in order to form the aforementioned air guide space 1201a without increasing the thickness of the main body 1211, the main body 1211 can also be disassembled and designed as two independent structural parts, and the two independent structural parts can form a complete main body 1211 after splicing, and can be jointly enclosed to form the air guide space 1201a after splicing, thereby omitting the design of the air guide space 1201a forming the second opening 1202b on the third side 1211c. In addition, in order to improve the sealing of the air guide space 1201a, the gap between the two spliced ​​structural parts can also be glued or filled with other airtight materials. In this embodiment, when the design of the sealing cover 122 is omitted, the inner wall of the air guide space 1201a can be used to form the aforementioned air duct 1201 together with the conducting part 1212 and the protruding part 1213.

[0067] Optionally, the first side 1211a may also be recessed toward the main body 1211 to form an escape space 1204 for evading the meter header mechanism 200, and the conducting portion 1212 and the buckle portion 1214 may be located in the escape space 1204. When the buckle portion 1214 and the conducting portion 1212 are simultaneously inserted into the meter header mechanism 200, the escape space 1204 may be used to evade the meter header mechanism 200 to avoid interference with the meter header mechanism 200, thereby ensuring that the buckle portion 1214 and the conducting portion 1212 can be inserted into place.

[0068] Optionally, the main body 1211 may also be bent toward the side of the strap 111 close to the wearing space, so that the main body 1211 may have an arc bent toward the wearing space, so that the end of the strap 111 embedded with the main body 1211 is bent, thereby forming a wearing space together with the watch head mechanism 200. At the same time, the sealing cover 122 may also match the third side 1211c of the main body 1211. That is, the surface of the sealing cover 122 exposed on the third side 1211c may also be an arc surface, so as to avoid the sealing cover 122 from forming a bulge on the third side 1211c. In addition, the thickness of the main body 1211 in the direction away from the conducting portion 1212 gradually decreases, so that the thickness of the strap 111 in the direction away from the conducting portion 1212 can also be gradually reduced, which is conducive to the thin and light design of the strap 111. Of course, the shape of the main body 1211 may also be not limited, and the specific shape of the main body 1211 may also be adaptively adjusted according to design requirements, which is not limited in this embodiment.

[0069] The main body 1211 can also be bent in the direction of the third side 1211c close to the second side 1211b, so that the main body 1211 as a whole can have a certain curvature to match the shape of the user's wrist, thereby reducing the gap between the user's wrist and the end of the strap 111 connecting the main body 1211, which is beneficial to improving the fit between the airbag body 1122 and the user's wrist after inflation.

[0070] Further, the conducting portion 1212 is connected to the first side 1211a, and can be inserted into the header mechanism 200 simultaneously when the buckle portion 1214 is inserted into the header mechanism 200, and the conducting portion 1212 is also provided with an air guide hole 1201b connecting the air guide space 1201a and the header mechanism 200, and the inner walls of the air guide space 1201a and the air guide hole 1201b can be used to form the aforementioned air channel 1201 together with the protruding portion 1213 and the sealing cover 122. Among them, the axial direction of the air guide hole 1201b can be parallel to the insertion direction of the conducting portion 1212, and the air guide hole 1201b can penetrate the two opposite sides of the conducting portion 1212 close to and away from the main body 1211, and at the same time penetrate the first side 1211a of the main body 1211, so as to be connected with the air guide space 1201a. With such a configuration, the air guide hole 1201 b can connect the air guide space 1201 a and the header mechanism 200 after the end of the conducting portion 1212 away from the main body 1211 is inserted into the header mechanism 200 .

[0071] Optionally, in order to reduce the probability of air leakage at the connection between the conducting part 1212 and the meter head mechanism 200, the connecting component 120 may also be provided with a sealing ring 123 ( Figure 5 and Figure 6), and when the conducting portion 1212 is inserted into the meter header mechanism 200, the sealing ring 123 can respectively abut against the conducting portion 1212 and the meter header mechanism 200 to fill the gap between the conducting portion 1212 and the meter header mechanism 200, thereby reducing the probability of air leakage at the connection between the conducting portion 1212 and the meter header mechanism 200. In this embodiment, the sealing ring 123 can also be made of elastic materials such as silicone, rubber, and soft plastic, so that the sealing ring 123 can respectively abut against the conducting portion 1212 and the meter header mechanism 200.

[0072] Optionally, the air guide hole 1201b may not be limited to passing through the side of the conducting portion 1212 away from the main body 1211, and the air guide hole 1201b may also pass through the peripheral side of the conducting portion 1212, and the strap mechanism 100 may also be connected to the air guide hole 1201b from the peripheral side of the conducting portion 1212.

[0073] Optionally, the design of the conducting portion 1212 can also be omitted. At this time, in order to achieve the connection between the air-conducting space 1201a and the header mechanism 200, the air-conducting space 1201a can also form a third opening on the first side 1211a, and the header mechanism 200 can be provided with a structure similar to the conducting portion 1212, and the third opening can avoid the header mechanism 200, so that the header mechanism 200 can be inserted into the air-conducting space 1201a through the third opening to achieve the connection between the header mechanism 200 and the air-conducting space 1201a. In this embodiment, when the design of the conducting portion 1212 is omitted, the inner wall of the air-conducting space 1201a can be used to form the aforementioned airway 1201 together with the protrusion 1213 and the sealing cover 122.

[0074] Furthermore, the protrusion 1213 is connected to the second side 1211b and is disposed through the strap 111, and the protrusion 1213 is also exposed on the side of the strap 111 facing the wearing space. At the same time, the protrusion 1213 can also be disposed around the first opening 1202a, and enclose a receiving hole 1201c that connects the air guide space 1201a and the air nozzle 1123, and the inner walls of the air guide space 1201a, the air guide hole 1201b, and the receiving hole 1201c can be used to form the aforementioned air channel 1201 together with the sealing cover 122. Among them, since the protrusion 1213 is provided through the strap 111, the receiving hole 1201c can be exposed on the side of the strap 111 facing the wearing space for the air nozzle 1123 to be inserted, and the sealing ring 1124 can abut against the air nozzle 1123 and the inner wall of the receiving hole 1201c respectively to improve the sealing of the air nozzle 1123 inserted into the protrusion 1213. In this embodiment, the air nozzle 1123 and the protrusion 1213 can be detachably connected or non-detachably connected, which is not limited in this embodiment.

[0075] Optionally, the opening diameter of the accommodating hole 1201c can be larger than the opening diameter of the first opening 1202a, so that the air nozzle 1123 can still contact the second side 1211b after being inserted into the accommodating hole 1201c, so as to use the second side 1211b to limit the insertion distance of the air nozzle 1123.

[0076] Optionally, when the airbag 112 is provided with a hard structure on the airbag body 1122 for the protrusion 1213 to be inserted, the protrusion 1213 can also be inserted into the hard structure to connect the air guide space 1201a and the airbag body 1122 through the receiving hole 1201c. Alternatively, the protrusion 1213 can also be directly inserted into the airbag body 1122 and fixedly connected to the airbag body 1122, so that the airbag body 1122 and the connector 121 are an integrated structure that is connected.

[0077] Optionally, the design of the protrusion 1213 can also be omitted. In this case, in order to achieve the communication between the air guide space 1201a and the header mechanism 200, the air nozzle 1123 can be directly inserted into the air guide space 1201a through the first opening 1202a to achieve the communication between the airbag body 1122 and the air guide space 1201a. In this embodiment, when the design of the protrusion 1213 is omitted, the inner wall of the air guide space 1201a can be used to form the aforementioned air channel 1201 together with the inner wall of the air guide hole 1201b and the sealing cover 122.

[0078] Optionally, the designs of the conducting portion 1212 and the protruding portion 1213 may also be omitted at the same time. In this case, the inner wall of the air guiding space 1201a and the sealing cover 122 may together form the aforementioned air passage 1201. Optionally, the designs of the conducting portion 1212, the protruding portion 1213 and the sealing cover 122 may also be omitted at the same time. In this case, the inner wall of the air guiding space 1201a may form the aforementioned air passage 1201.

[0079] Optionally, when there are two air nozzles 1123, there may also be two air passages 1201, so as to be connected to the two air nozzles 1123 respectively. Figures 5 to 8As shown, the main body 1211 may have two independent air guide spaces 1201a. The number of the conducting parts 1212 may also be two, and they are respectively connected to the two air guide spaces 1201a, and the two conducting parts 1212 are also used to insert the header mechanism 200. The number of the protruding parts 1213 may also be two, and they are respectively connected to the two air guide spaces 1201a, and the two protruding parts 1213 are also respectively connected to the two air nozzles 1123. The number of the sealing covers 122 may also be two, and the two sealing covers 122 are respectively used to block the two second openings 1202b formed on the third side 1211c of the two air guide spaces 1201a. In this embodiment, the two air guide spaces 1201a, the two conducting parts 1212, the two protruding parts 1213 and the two sealing covers 122 can be symmetrically arranged about the length direction L. The matching relationship between the single air guiding space 1201a and the conducting portion 1212, the protruding portion 1213 and the sealing cover 122 can be referred to in the above-mentioned embodiments, which will not be described in detail here.

[0080] Furthermore, the buckle portion 1214 is connected to the first side 1211a and is used to be inserted into the watch header mechanism 200 so as to be detachably connected to the watch header mechanism 200. Figures 7 and 8 As shown, the buckle portion 1214 may be provided with a slot 12141, and when the buckle portion 1214 is inserted into the header mechanism 200, the matching structure of the header mechanism 200 can enter the slot 12141 and be engaged with the buckle portion 1214 in the direction of exiting the header mechanism 200, so as to realize the fixed connection between the buckle portion 1214 and the header mechanism 200. At the same time, the matching structure of the header mechanism 200 can also exit the slot 12141 to release the engagement state with the buckle portion 1214, so that the buckle portion 1214 can be removed from the header mechanism 200, so as to realize the detachable connection between the buckle portion 1214 and the header mechanism 200. In this embodiment, when the number of the conducting portions 1212 is two, the buckle portion 1214 is also located between the two conducting portions 1212 arranged at intervals.

[0081] Optionally, in addition to being used for detachably connecting with the watch header mechanism 200, the buckle portion 1214 may also be provided with the aforementioned air guide hole 1201b, so as to be synchronously connected with the watch header mechanism 200 when inserted into the watch header mechanism 200. That is, the buckle portion 1214 can simultaneously play the role of detachably connecting with the watch header mechanism 200 and being connected with the watch header mechanism 200. In this embodiment, when the buckle portion 1214 has the air guide hole 1201b, the design of the conducting portion 1212 can be omitted, and the way of opening the air guide hole 1201b on the buckle portion 1214 can be the same as or similar to the aforementioned embodiment, which is not described in detail here.

[0082] Optionally, the number of the buckle parts 1214 can be two, and the two buckle parts 1214 are arranged between the two conductive parts 1212 at intervals, and are respectively used to be inserted into the header mechanism 200 to be detachably connected with the header mechanism 200, thereby improving the connection stability between the connection assembly 120 and the header mechanism 200. Among them, the two buckle parts 1214 can also be symmetrically arranged to improve the consistency of the insertion of the two into the header mechanism 200. At the same time, the card slots 12141 on the two buckle parts 1214 can all penetrate the side of the two buckle parts 1214 close to each other, so as to form corresponding avoidance positions between the two buckle parts 1214, so as to facilitate the matching structure of the header mechanism 200 to enter the card slot 12141. Of course, the specific design of the card slot 12141 can also be adaptively adjusted according to the needs, and it is only necessary that the matching structure of the header mechanism 200 can enter the card slot 12141 and be connected with the buckle part 1214, and this embodiment is not limited to this.

[0083] See also Figures 9 to 13 , Fig. 9 yes Figure 1 Another partial cross-sectional structural diagram of the wearable device 10 along V-V, Fig.10 yes Fig. 9 A schematic diagram of the structure of the connecting component 120, Fig.11 yes Fig.10 A schematic diagram of the structure of the middle connector 121, Fig.12 yes Fig.10 A schematic diagram of the structure of the middle air guide 124, Fig.13 yes Fig.10 A partial enlarged view of point A in the middle.

[0084] In addition to using the connector 121 and the sealing cover 122 to form the air passage 1201, the air passage 1201 may also be formed by using other independent structural members. Figures 9 and 10As shown, the connection assembly 120 provided in this embodiment may include: a connection head 121 and an air guide 124. The connection head 121 may be connected to the end of the watch strap 111, and the connection head 121 may also be assembled on the watch head mechanism 200 and detachably connected to the watch head mechanism 200. The air guide 124 may be provided on the connection head 121, and the air guide 124 may be formed with an air channel 1201, so as to respectively connect the airbag body 1122 and the watch head mechanism 200 when the connection head 121 is connected to the watch head mechanism 200, so as to realize the inflation and deflation of the airbag body 1122 by the watch head mechanism 200. In this way, the connection assembly 120 can play a fixing role in the connection between the airway 1201 and the header mechanism 200 through a detachable connection with the header mechanism 200, so that the header mechanism 200 can omit the structure required for fixing the airway 1201, so as to increase the available space of the header mechanism 200, thereby reducing the limitations on the design and internal device layout of the header mechanism 200 due to insufficient space. The structure of the connector 121 and the air guide 124 provided in this embodiment is further described below.

[0085] like Figures 9 to 11 As shown, the connector 121 is inserted into the watch header mechanism 200 and is detachably connected to the watch header mechanism 200, and the connector 121 may include: a main body 1211 and a buckle portion 1214. The shape of the main body 1211 is the same or similar to that of the above-mentioned embodiment, except that the main body 1211 provided in this embodiment does not have an air guide space 1201a, and the main body 1211 is only used to install the air guide 124 and connect with the strap 111. For example, the main body 1211 is provided with a mounting groove 1205 that runs through the first side 1211a and the second side 1211b, and the mounting groove 1205 can be used to install the air guide 124, and the air channel 1201 formed by the air guide 124 can be connected to the watch header mechanism 200 from the first side 1211a, and connected to the airbag body 1122 from the second side 1211b. In addition, the shape of the buckle portion 1214 and the matching relationship with the watch header mechanism 200 are the same as or similar to those in the above-mentioned embodiment and are not described in detail here.

[0086] The air guide 124 is disposed in the mounting groove 1205, and when the connector 121 (the buckle portion 1214) is inserted into the meter header mechanism 200, the air guide 124 can be inserted into the meter header mechanism 200 simultaneously, so that the air passage 1201 is connected to the meter header mechanism 200. Figures 9 to 12As shown, the air guide 124 includes: an air guide tube 1241 and a fixing plate 1242. The air guide tube 1241 is arranged in the mounting groove 1205 and has an air passage 1201, and the air guide tube 1241 is also respectively protruded from the first side 1211a and the second side 1211b to be connected to the meter header mechanism 200 and the airbag body 1122, so as to achieve the communication between the air passage 1201 and the meter header mechanism 200 and the airbag body 1122. The fixing plate 1242 is sleeved on the part of the air guide tube 1241 protruding from the first side 1211a, and is connected to the first side 1211a, and is used to fix the air guide tube 1241 in the mounting groove 1205. In this embodiment, the material of the air duct 1241 can be plastic, the material of the fixing plate 1242 can be metal, and the air duct 1241 and the fixing plate 1242 can be made in one piece by a metal insert injection molding process to improve the connection firmness between the two. Of course, the air duct 1241 and the fixing plate 1242 can also be fixedly connected by other means, as long as the fixing plate 1242 can play the role of fixing the air duct 1241.

[0087] Exemplarily, the air guide tube 1241 may include: a first air guide tube 1241a and a second air guide tube 1241b. One end of the first air guide tube 1241a is located in the mounting groove 1205, and the other opposite end is protruding from the first side 1211a, and is used to be inserted into the meter header mechanism 200 when the buckle portion 1214 is inserted into the meter header mechanism 200, and the first air guide tube 1241a is also provided with a first air hole 1206a connected to the meter header mechanism 200, and the first air hole 1206a can also pass through the side of the first air guide tube 1241a away from the second air guide tube 1241b. One end of the second air guide tube 1241b is connected to one end of the first air guide tube 1241a located in the installation groove 1205, and the other opposite end is protruded from the second side 1211b and protrudes from the side of the strap 111 facing the wearing space, so as to be inserted into the airbag body 1122, and the second air guide tube 1241b is also provided with a second air hole 1206b connecting the first air hole 1206a and the airbag body 1122, and the second air hole 1206b can pass through the side of the second air guide tube 1241b away from the first air guide tube 1241a. In this embodiment, the inner walls of the first air hole 1206a and the second air hole 1206b are used to form an airway 1201 to connect the watch head mechanism 200 and the airbag body 1122, so that the watch head mechanism 200 can inflate and deflate the airbag body 1122.

[0088] Optionally, the first air guide tube 1241a can be used to insert the header mechanism 200, and can also be inserted into the header mechanism 200. That is, the header mechanism 200 can also be inserted into the first air hole 1206a to achieve communication with the airway 1201. At the same time, when the first air guide tube 1241a is inserted into the header mechanism 200, the first air guide tube 1241a can also be arranged without protruding from the first side 1211a, but only located in the installation groove 1205.

The following only takes the cooperation between a single air outlet 2322 and the vent 2115 as an example for explanation. The air pump assembly 230 includes a hose 233, and one end of the hose 233 can be connected to the air outlet 2322 (such as being sleeved on the air outlet 2322), and the other end of the hose 233 extends into the receiving groove 21155 and is connected to the boss 21154 (such as being sleeved on the boss 21154) to connect the air outlet 2322 and the through hole 2013, so that the air flow can enter the ventilation space 2012 through the air outlet 2322, the hose 233 and the through hole 2013. In this embodiment, the valve 232 is preferably a three-way valve to cooperate with the two ventilation parts 2115 respectively. The hose 233 can be respectively interference-fitted with the air outlet 2322 and the boss 21154 to improve the sealing of the connection between the hose 233 and the air outlet 2322 and the boss 21154.

[0123] Optionally, in order to power the valve 232, the valve 232 can also be connected to the electrical connector 223. Among them, when the number of the vents 2115 is two, since the electrical connector 223 is to be connected to the support plates 221 on the two vents 2115 at the same time, the electrical connector 223 can cover the area between the two vents 2115. Based on this, the valve 232 can also be arranged on the area where the electrical connector 223 is located between the two vents 2115, so that the electrical connector 223 can also power the valve 232. Such a setting is conducive to reducing the number of wirings in the installation space 2111, thereby reducing the cost, compared with the solution of independently routing the valve 232 for power supply, so as to play a role in reducing the cost. In this embodiment, since the valve 232 is arranged on the electrical connector 223, the side of the valve 232 away from the electrical connector 223 can be provided with an air inlet 2321 connected to the air cavity 23111.
