Description

Technical Field

[0001] This application relates to the technical field of wearable devices, specifically to a wearable device, a watch strap mechanism, and a watch head mechanism. Background Technology

[0002] Currently, common blood pressure measurement solutions in smartwatches involve placing an air bladder on the watch band and inflating it via the watch head. This inflates the bladder to compress and block the user's blood vessels for blood pressure measurement. The air valve for the air bladder is typically located on the watch head, connecting to an internal air pump that inflates the bladder. The watch head also includes a retaining structure to secure the valve and improve the connection. However, this retaining structure generally occupies some space on the watch head, reducing usable space and limiting the watch's design and the layout of its internal components. Summary of the Invention

[0003] This application provides a wearable device, comprising: a watch head mechanism and a watch strap mechanism, wherein the watch strap mechanism comprises: a watch strap assembly and an airbag assembly; the watch head mechanism has a mounting surface in the thickness direction and a mounting groove is formed on the mounting surface, and the watch head mechanism is further configured to control the expansion or contraction of the airbag assembly; the watch strap assembly is configured to be inserted into the mounting groove from the mounting surface and is detachably connected to the watch head mechanism; the airbag assembly is disposed on the watch strap assembly and communicates with the watch head mechanism after being inserted into the mounting groove along with the watch strap assembly.

[0004] In another aspect, this application provides a watch strap mechanism for connection to a watch head mechanism, wherein the watch head mechanism has a mounting surface in the thickness direction and a mounting groove is formed on the mounting surface. The watch strap mechanism includes a watch strap assembly and an airbag assembly. The watch strap assembly includes a fixing seat and a watch strap connected to the fixing seat. The fixing seat is configured to be inserted into the mounting groove from the mounting surface and is detachably connected to the watch head mechanism. The airbag assembly includes an air nozzle and an airbag connected to the air nozzle. The air nozzle is disposed on the fixing seat and connects the airbag and the watch head mechanism after being inserted into the mounting groove along with the fixing seat. The watch head mechanism is also configured to control the inflation or deflation of the airbag.

[0005] This application also provides a watch head mechanism connected to a watch strap mechanism, wherein the watch strap mechanism includes a watch strap assembly and an airbag assembly, and the watch head mechanism includes a housing assembly, an air pump assembly, and a sliding assembly; the housing assembly has a mounting surface in the thickness direction and a mounting groove is formed on the mounting surface; the air pump assembly is disposed inside the housing assembly, and the housing assembly also has an air guide hole communicating with the air pump assembly and the mounting groove; the sliding assembly is slidably connected to the housing assembly, and the sliding assembly is also exposed outside the housing assembly and protrudes from the bottom wall of the mounting groove; wherein, the watch strap assembly is configured to be inserted into the mounting groove from the mounting surface and detachably connected to the sliding assembly; the airbag assembly is configured to be inserted into the mounting groove along with the watch strap assembly and inserted into the air guide hole, and the air pump assembly is configured to inflate or deflate the airbag assembly through the air guide hole to control the expansion or contraction of the airbag assembly.

[0006] The wearable device provided in this application, by placing the airbag assembly on the watch band assembly, and when the watch band assembly is detachably connected to the watch head mechanism by being inserted into the mounting slot, the airbag assembly can also be inserted into the mounting slot along with the watch band assembly and communicate with the watch head mechanism. This allows the airbag assembly to be fixed using the detachable connection between the watch band assembly and the watch head mechanism, maintaining the communication between the airbag assembly and the watch head mechanism. With this configuration, the wearable device can reuse the detachable connection between the watch band assembly and the watch head mechanism, allowing the structure required to fix the airbag assembly in the watch head mechanism to be omitted, thereby increasing the usable space in the watch head mechanism and reducing the limitations imposed by insufficient space on the design and internal component layout of the watch head mechanism.

[0020] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0021] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] Please see Figures 1 to 3 , Figure 1 This is a partial structural schematic diagram of the wearable device 10 provided in an embodiment of this application. Figure 2 yes Figure 1 A structural diagram of the central header mechanism 100. Figure 3 yes Figure 1 A schematic diagram of the cross-sectional structure of the central meter head mechanism 100 along section V-V.

[0023] The wearable device 10 provided in this application can be a smartwatch, a smart bracelet, or a cuff-type blood pressure measuring device, etc. The following example uses a smartwatch as the wearable device 10. Figure 1 As shown, the wearable device 10 includes a watch head mechanism 100 and a watch strap mechanism 200. The watch head mechanism 100 and the watch strap mechanism 200 are detachably connected and together form a wearing space 300, through which the user can wear the watch head mechanism 100 and the watch strap mechanism 200 on their wrist. Simultaneously, the watch head mechanism 100 is also connected to the watch strap mechanism 200 and can control the expansion or contraction of the watch strap mechanism 200. Furthermore, the watch strap mechanism 200 can compress blood vessels in the user's wrist after expansion to facilitate blood pressure measurement. In this embodiment, the detachable connection and communication between the watch head mechanism 100 and the watch strap mechanism 200 can be implemented simultaneously, allowing the structure required for maintaining communication with the watch head mechanism 100 to be omitted, thereby increasing the available space of the watch head mechanism 100 and reducing the limitations imposed on the design and internal component layout of the watch head mechanism 100 due to insufficient space.

[0024] For example, the head unit 100 is detachably connected to the strap unit 200, and the strap unit 200 can be controlled to expand or contract to cooperate with the strap unit 200 in realizing the blood pressure measurement function. Figures 2 to 3 As shown, the watch head mechanism 100 has a mounting surface 101 in the thickness direction Z, and a mounting groove 102 is formed on the mounting surface 101. The watch strap mechanism 200 can be inserted into the mounting groove 102 from the mounting surface 101, and can be detachably connected and communicated with the watch head mechanism 100 simultaneously. The mounting surface 101 may include a top surface 1011 and a bottom surface 1012, and one of the top surface 1011 and the bottom surface 1012 may have a mounting groove 102 formed therein. The watch strap mechanism 200 is inserted into the mounting groove 102 from the one of the top surface 1011 and the bottom surface 1012 with the mounting groove 102 formed therein. Meanwhile, the watch head mechanism 100 also has a side surface 1013 that connects the top surface 1011 and the bottom surface 1012 respectively, and the mounting groove 102 can also penetrate through the side surface 1013 to avoid the watch strap mechanism 200 when it is installed in the mounting groove 102, thereby improving the integrated effect of the watch head mechanism 100 and the watch strap mechanism 200 in appearance.

[0025] Alternatively, the mounting groove 102 may not penetrate the side 1013. In this case, the watch strap mechanism 200 can be mounted on one of the top surface 1011 and the bottom surface 1012 where the mounting groove 102 is provided, and has a mating structure protruding from the mounting groove 102 to communicate with and detachably connect with the watch head mechanism 100.

[0026] When the watch head mechanism 100 and the watch strap mechanism 200 together form the wearing space 300, the top surface 1011 can specifically be the side of the watch head mechanism 100 facing away from the wearing space 101. Furthermore, when the watch head mechanism 100 has a display function, a portion of the top surface 1011 can also serve as the display surface for the watch head mechanism 100, allowing the user to view it. Simultaneously, the bottom surface 1012 can specifically be the side of the watch head mechanism 100 facing the wearing space 101, and can contact the user's wrist. When the watch head mechanism 100 has a heart rate detection function (such as being equipped with an ECG or PPG module), the bottom surface 1012 can also serve as the electrode contact surface or the light-emitting surface of the watch head mechanism 100 to acquire the user's biometric information. The following explanation uses an example where the top surface 1011 has a mounting groove 102 that extends through the side surface 1013.

[0027] like Figures 2 to 3 As shown, the meter mechanism 100 includes a housing assembly 110 and an air pump assembly 120. The housing assembly 110 has a top surface 1011 and a bottom surface 1012 disposed opposite to each other in the thickness direction Z, and side surfaces 1013 connecting the top surface 1011 and the bottom surface 1012 respectively. The housing assembly 110 also has the aforementioned mounting groove 102. Furthermore, the housing assembly 110 has a receiving space 1101, which can be used to install the air pump assembly 120 and other functional components required for the meter mechanism 100, such as batteries, microphones, speakers, pressure sensors, ECG modules, and PPG modules. In addition, the housing assembly 110 is provided with an air guide hole 1102 on the bottom wall of the assembly groove 102, which connects to the receiving space 1101. The air guide hole 1102 can be used to connect the air pump assembly 120 and the watch strap mechanism 200, so that the air pump assembly 120 can charge and depress the watch strap mechanism 200 through the air guide hole 1102 to control the expansion or contraction of the watch strap mechanism 200.

[0028] Exemplarily, the housing assembly 110 may include a frame 111 and a rear cover 112. The frame 111 may enclose a receiving space 1101, and the rear cover 112 may cover the side of the receiving space 1101 where an opening is formed on the frame 111, thus closing the receiving space 1101. Simultaneously, the side of the frame 111 facing away from the rear cover 112 may form a top surface 1011, while the side of the rear cover 112 facing away from the frame 111 may form a bottom surface 1012. The side of the frame 111 facing away from the receiving space 1101 may be a side surface 1013 connecting the top surface 1011 and the bottom surface 1012, respectively. In this embodiment, the frame 111 may have the aforementioned mounting groove 102, and the aforementioned air vent 1102 may be formed on the bottom wall of the mounting groove 102.

[0029] The air outlet structure of the air pump assembly 120 can be inserted into the air guide hole 1102, and the watch strap mechanism 200 can also be inserted into the air guide hole 1102 simultaneously after being installed in the mounting slot 102, so that the air pump assembly 120 and the watch strap mechanism 200 can be connected through the air guide hole 1102. Similarly, the air pump assembly 120 and the watch strap mechanism 200 can also be inserted into the air guide structure of the frame 111 forming the air guide hole 1102, so as to achieve communication between the air pump assembly 120 and the watch strap mechanism 200 through the air guide hole 1102. In this embodiment, the watch strap mechanism 200 preferably achieves communication with the air guide hole 1102 by insertion or being inserted, so as to simplify the steps required to connect the watch strap mechanism 200 and the air guide hole 1102, which is beneficial to improve the convenience of the watch strap mechanism 200 to be detachably connected and connected with the watch head mechanism 100. However, the air pump assembly 120 and the air guide hole 1102 can also be connected in other ways, which are not limited in this embodiment.

[0030] The number of air vents 1102 can also be two, and the two air vents 1102 can be spaced apart on the bottom wall of the assembly groove 102, and both are connected to the air pump assembly 120. When the watch strap mechanism 200 is installed into the assembly groove 102, the watch strap mechanism 200 can be simultaneously inserted into the two air vents 1102, and the air pump assembly 120 can inflate or deflate the watch strap mechanism 200 through the two air vents 1102 respectively, to control the expansion or contraction of the watch strap mechanism 200. Of course, the number of air vents 1102 is not limited to two, and the number of air vents 1102 can be adaptively adjusted according to design requirements; this embodiment does not limit this.

[0031] When the meter head mechanism 100 has a display function, the meter head mechanism 100 may further include a display component 130. The receiving space 1101 can extend through opposite sides of the frame 111, the back cover 112 can cover the side of the receiving space 1101 where an opening is formed on the frame 111, and the display component 130 can cover the other opposite side of the receiving space 1101 where an opening is formed on the frame 111, so that the back cover 112 and the display component 130, together with the frame 111, can form a closed receiving space 1101. Simultaneously, the side of the display component 130 and the side of the frame 111 facing away from the back cover 112 can together form a top surface 1011, while the side of the back cover 112 facing away from the frame 111 can be used to form a bottom surface 1012, and the side of the frame 111 facing away from the receiving space 1101 can be a side surface 1013 connecting the top surface 1011 and the bottom surface 1012 respectively. In this embodiment, a portion of the top surface 1011 corresponding to the display component 130 can serve as a display surface, while a portion of the top surface 1011 corresponding to the frame 111 can be provided with a mounting groove 102, and the mounting groove 102 is preferably located at the edge of the top surface 1011 away from the display component 130.

[0032] It is understood that the aforementioned embodiment of the housing assembly 110 including the frame 111 and the back cover 112 is an illustrative example. The specific structure of the housing assembly 110 can be adjusted or changed according to design requirements, and is not limited to including the frame 111 and the back cover 112. It is only necessary that the housing assembly 110 has a top surface 1011, a bottom surface 1012 and a side surface 1013, and has an assembly groove 102 and a vent hole 1102. This embodiment does not limit this.

[0033] Please combine Figure 2 See Figures 4 to 5 , Figure 4 yes Figure 1 A schematic diagram of a partial cross-sectional structure of the central meter head mechanism 100 along line VI-VI. Figure 5 yes Figure 4 A schematic diagram of the structure of the card connector 141.

[0034] To enable a detachable connection between the watch head mechanism 100 and the watch strap mechanism 200, the watch head mechanism 100 may further include a sliding component 140. For example... Figure 2 and Figure 4As shown, the sliding component 140 is slidably connected to the housing component 110 and is exposed on the bottom surface 1012, and the sliding component 140 also protrudes from the bottom wall of the mounting groove 102. When the watch strap mechanism 200 is inserted into the mounting groove 102, the watch strap mechanism 200 can push against the sliding component 140 to slide and avoid it, allowing the watch strap mechanism 200 to be inserted into the mounting groove 102. After the watch strap mechanism 200 is in place, the sliding component 140 can reset and engage with the watch strap mechanism 200 to prevent the watch strap mechanism 200 from detaching from the top surface 1011 and exiting the mounting groove 102. Simultaneously, the user can press the sliding component 140 from the bottom surface 1012 to slide it, and the sliding component 140 can release its engagement with the watch strap mechanism 200 after being pressed and slid, allowing the watch strap mechanism 200 to detach from the top surface 1011 and exit the mounting groove 102. With this configuration, when the watch strap mechanism 200 is installed into the mounting slot 102, the sliding component 140 can cooperate with the watch strap mechanism 200 to achieve a detachable connection between the watch head mechanism 100 and the watch strap mechanism 200.

[0035] For example, the sliding component 140 includes a snap-fit ​​member 141 and an elastic member 142. (As...) Figure 2 and Figure 4 As shown, the snap-fit ​​member 141 is slidably connected to the housing assembly 110 and is exposed on the bottom surface 1012, and the snap-fit ​​member 141 also protrudes from the bottom wall of the mounting groove 102. The elastic member 142 is disposed between the snap-fit ​​member 141 and the housing assembly 110, and is located on the sliding path of the snap-fit ​​member 141. When the watch strap mechanism 200 is inserted into the mounting groove 102, the watch strap mechanism 200 can push against the snap-fit ​​member 141 to slide and avoid it, and the snap-fit ​​member 141 can also press against the elastic member 142 to undergo elastic deformation. After the watch strap mechanism 200 is in place, the snap-fit ​​member 141 can reset under the elastic force provided by the elastic member 142 and snap into the watch strap mechanism 200. Simultaneously, the user can press and slide the latching member 141 from the bottom surface 1012. The latching member 141, after being pressed and slid, can disengage from the strap mechanism 200 and elastically deform against the elastic element 142, allowing it to reset using the elastic force of the elastic element 142 after the strap mechanism 200 disengages from the mounting slot 102. This configuration allows the latching member 141 to reset using the elastic force of the elastic element 142 after sliding under pressure or pushing, thus achieving a detachable connection with the watch head mechanism 100.

[0036] The housing assembly 110 has a sliding space 1103 for mounting the snap-fit ​​member 141. For example... Figure 4As shown, the side of the frame 111 facing away from the bottom wall of the mounting groove 102 can form a sliding space 1103 together with the edge area of ​​the back cover 112. The sliding space 1103 can also penetrate the frame 111 and the back cover 112, and form a first opening 1103a and a second opening 1103b on the bottom surface 1012 and the bottom wall of the mounting groove 102, respectively. The snap-fit ​​member 141 can be disposed in the sliding space 1103, and the snap-fit ​​member 141 can also be exposed on the bottom surface 1012 through the first opening 1103a, so that the user can press the snap-fit ​​member 141 on the bottom surface 1012. At the same time, the snap-fit ​​member 141 can also protrude from the bottom wall of the mounting groove 102 through the second opening 1103b, so as to detachably connect with the watch strap mechanism 200 when the watch strap mechanism 200 is installed in the mounting groove 102.

[0037] The snap-fit ​​component 141 includes a pressing part 1411 and a hook part 1412. For example... Figure 4 and Figure 5 As shown, the pressing part 1411 is located within the sliding space 1103 and is exposed on the bottom surface 1012 through the first opening 1103a, allowing the user to press it. The pressing part 1411 also has a fixing post 14111, and one end of the elastic member 142 can be sleeved on the fixing post 14111 to connect the elastic member 142 with the snap-fit ​​member 141. The hook part 1412 is connected to the pressing part 1411 and protrudes from the bottom wall of the assembly groove 102 through the second opening 1103b. When the watch strap mechanism 200 is inserted into the assembly groove 102, the watch strap mechanism 200 can push against the hook part 1412 to slide and avoid it, causing the pressing part 1411 to slide and press against the elastic member 142. Once the watchband mechanism 200 is in place, the hook portion 1412 can be reset under the elastic force of the elastic member 142 and engage with the watchband mechanism 200. Similarly, when the user presses the pressing part 1411, the pressing part 1411 can drive the hook portion 1412 to slide and press against the elastic member 142 to undergo elastic deformation, thereby releasing the hook portion 1412 from the watchband mechanism 200.

[0038] Optionally, the side of the pressing part 1411 exposed on the bottom surface 1012 is also located between the bottom surface 1012 and the side surface 1013. That is, the sliding space 1103 has a first opening 1103a in the edge region where the bottom surface 1012 and the side surface 1013 meet. With this arrangement, compared to the solution where the pressing part 1411 is exposed on the bottom surface 1012 by passing through the rear cover 112, the step of assembling the pressing part 1411 and the rear cover 112 can be omitted, thereby improving the assembly convenience of the snap-fit ​​member 141 and the housing assembly 110.

[0039] Optionally, the sliding space 1103 may have two second openings 1103b formed on the bottom wall of the assembly groove 102, and the snap-fit ​​member 141 may be provided with two snap hook portions 1412. Figure 2 and Figure 5 As shown, the two second openings 1103b can be spaced apart, and the two hook portions 1412 can be spaced apart and connected to the same side of the pressing portion 1411. The two hook portions 1412 can each protrude from the bottom wall of the mounting groove 102 through the two second openings 1103b, and both hook portions 1412 can cooperate with the watch strap mechanism 200 to achieve a detachable connection between the watch head mechanism 100 and the watch strap mechanism 200. This arrangement, with the two hook portions 1412 cooperating with the watch strap mechanism 200, helps to improve the connection stability between the watch head mechanism 100 and the watch strap mechanism 200. It is understood that the cooperation method between the two hook portions 1412 and the watch head mechanism 100 is the same as or similar to that in the aforementioned embodiment, and will not be described in detail in this embodiment.

[0040] The housing assembly 110 also has a receiving hole 1104 for mounting the resilient element 142. For example... Figure 4 As shown, the frame 111 is located on one side within the sliding space 1103, that is, the inner wall of the sliding space 1103 has a receiving hole 1104 that connects to the receiving space 1101. The housing assembly 110 also has a baffle 113 located within the receiving space 1101 and covering the receiving hole 1104. An elastic member 142 can be disposed within the receiving hole 1104, and the opposite ends of the elastic member 142 can be connected to the baffle 113 and the snap-fit ​​member 141 respectively. After the snap-fit ​​member 141 slides, it is subjected to pressure from the baffle 113 and the snap-fit ​​member 141, resulting in elastic deformation to provide elastic force for the snap-fit ​​member 141 to reset. In this embodiment, the receiving hole 1104 can be specifically formed by opening the frame 111 on one side within the receiving space 1101, and the baffle 113 is used to cover the receiving hole 1104 and support the elastic member 142. This design, compared to having a receiving hole 1104 on the inner wall of the sliding space 1103, helps to reduce the processing difficulty of the receiving hole 1104.

[0041] Optionally, the elastic element 142 can be a spring. Of course, besides a spring, the elastic element 142 can also be other structural components capable of generating elastic force. For example, the elastic element 142 can also be made of an elastic material such as rubber or silicone filled in the receiving hole 1104, and the fixing post 14111 can be inserted into the receiving hole 1104. When the latching member 141 slides, the fixing post 14111 can press against the elastic element 142, causing the elastic element 142 to undergo elastic deformation, thereby providing elastic force to drive the latching member 141 to reset. Simultaneously, the fixing post 14111, inserted into the receiving hole 1104, can also cooperate with the inner wall of the receiving hole 1104 to provide guidance for the sliding of the latching member 141, thereby improving the sliding consistency of the latching member 141. It is understandable that when the elastic element 142 is a spring, the fixing post 14111 can also be inserted into the receiving hole 1104 so that the fixing post 14111 can press against the elastic element 142 to cause elastic deformation.

[0042] The watch head mechanism 100 provided in this embodiment of the application, by providing a hook portion 1412 on the bottom wall of the assembly groove 102 and opening an air guide hole 1102 on the bottom wall of the assembly groove 102 to connect with the air pump assembly 120, allows the watch strap mechanism 200 to simultaneously engage with the hook portion 1412 and the air guide hole 1102 when it is installed into the assembly groove 102 from the top surface 1011, thereby simultaneously realizing the connection and detachable connection between the watch strap mechanism 200 and the watch head mechanism 100. With this configuration, the structure on the housing assembly 110 used to fix the watch strap mechanism 200 and the air guide hole 1102 can be omitted from the watch head mechanism 100, increasing the usable space of the watch head mechanism 100 and reducing the limitations on the shape design and internal component layout of the watch head mechanism 100 due to insufficient space. Furthermore, the simplification of the structure of the watch head mechanism 100 also helps to reduce material and assembly costs.

[0043] Please see Figures 6 to 8 , Figure 6 yes Figure 1 A structural diagram of the middle section of the watch strap mechanism 200. Figure 7 yes Figure 1 A schematic diagram of a partial cross-sectional structure of the wearable device 10 along line VI-VI. Figure 8 yes Figure 6 A schematic diagram of the structure of the middle fixed base 211.

[0044] The watch strap mechanism 200 is inserted into the mounting slot 102 from the top surface 1011 and into the vent hole 1102. The watch strap mechanism 200 can also be detachably connected to the hook portion 1412. For example... Figure 6As shown, the watch strap mechanism 200 includes a watch strap assembly 210 and an airbag assembly 220. The watch strap assembly 210 can be inserted into the mounting groove 102 from the top surface 1011 and is detachably connected to the hook portion 1412. The airbag assembly 220 is disposed on the watch strap assembly 210 and can be simultaneously inserted into the air vent 1102 during the insertion of the watch strap assembly 210 into the mounting groove 102, thereby communicating with the air pump assembly 120. The air pump assembly 120 can inflate and deflate the airbag assembly 220 through the air vent 1102 to control the expansion or contraction of the airbag assembly 220.

[0045] With the above configuration, since the airbag assembly 220 can be simultaneously inserted into the air vent 1102 and connected to the air pump assembly 120 during the detachable connection between the strap assembly 210 and the hook portion 1412, the detachable connection between the strap assembly 210 and the hook portion 1412 can also fix the connection between the airbag assembly 220 and the air pump assembly 120. This allows the watch head mechanism 100 to omit the structure on the housing assembly 110 for fixing the airbag assembly 220, thereby increasing the available space on the housing assembly 110 and reducing the limitations on the shape design and internal component layout of the watch head mechanism 100 due to insufficient space. In addition, compared to the scheme where the airbag assembly 220 is fixed independently to the watch head mechanism 100, the user only needs to complete the disassembly and assembly of the strap assembly 210 and the airbag assembly 220 to the watch head mechanism 100 in one operation, which improves the convenience of the user in disassembling and assembling the strap mechanism 200.

[0046] For example, the watch strap assembly 210 includes: a mounting base 211 and a watch strap 212. (As...) Figures 6 to 7 As shown, the mounting base 211 can be inserted into the mounting groove 102 from the top surface 1011 and is detachably connected to the hook portion 1412. The mounting base 211 is also connected to the airbag assembly 220, so that the airbag assembly 220 can be inserted into the mounting groove 102 along with the mounting base 211 to insert into the air guide hole 1102, thereby achieving communication with the air pump assembly 120. The watch strap 212 can be connected to the mounting base 211 and can be formed together with the housing assembly 110 to form the aforementioned wearing space 300. The airbag assembly 220 is also located on the side of the watch strap 212 facing the wearing space 300, so that the airbag assembly 220 can contact the user to improve the effect of the airbag assembly 220 compressing the user's wrist.

[0047] The mounting base 211 has a mounting side 2111 facing the bottom wall of the mounting groove 102, and a supporting portion 2112 is provided on the mounting side 2111, which is used for detachable connection with the hook portion 1412. Figures 7 to 8As shown, the supporting portion 2112 can protrude from the mounting side 2111 and has a first surface 2112a and a second surface 2112b disposed opposite to each other. The first surface 2112a can be disposed away from the mounting side 2111, while the second surface 2112b can be disposed opposite to and spaced apart from the mounting side 2111. When the fixing seat 211 is inserted into the assembly groove 102, the first surface 2112a of the supporting portion 2112 can contact the hook portion 1412 and push the hook portion 1412 to slide and avoid it. After the fixing base 211 is installed in place, the first surface 2112a can separate from the hook portion 1412, allowing the hook portion 1412 to reset under the action of elasticity and return to the position between the second surface 2112b and the mounting side 2111. The hook portion 1412 can also engage with the second surface 2112b to prevent the fixing base 211 from detaching from the top surface 1011 and exiting the assembly slot 102. Furthermore, when the user presses the pressing portion 1411, the hook portion 1412 can slide out of the area between the second surface 2112b and the mounting side 2111, releasing the engagement with the second surface 2112b and allowing the fixing base 211 to detach from the top surface 1011.

[0048] Optionally, the first surface 2112a can be an inclined surface, allowing the fixing seat 211 to slide against the hook portion 1412 via the first surface 2112a. Simultaneously, the hook portion 1412 may also have a mating surface parallel to the first surface 2112a, through which the first surface 2112a can contact the hook portion 1412 to push it and slide.

[0049] Optionally, to reduce the sliding stroke of the hook portion 1412, the abutment portion 2112 may also have a third surface 2112c connecting the first surface 2112a and the second surface 2112b. When the fixing seat 211 is inserted into the mounting groove 102, the hook portion 1412 can contact the first surface 2112a and, during the pushing process by the first surface 2112a, slide from the first surface 2112a to the third surface 2112c. The third surface 2112c can only abut against the hook portion 1412 to maintain the state of the hook portion 1412 pressing against the elastic member 142. When the fixing seat 211 is in place, the hook portion 1412 can separate from the third surface 2112c, allowing the hook portion 1412 to return to its original position between the second surface 2112b and the mounting side 2111 under elastic force, so as to engage with the second surface 2112b. With this configuration, compared to the hook portion 1412 transitioning directly from the first surface 2112a to the second surface 2112b, the third surface 2112c can reduce the sliding stroke of the hook portion 1412, thereby avoiding the problem of the hook portion 1412 occupying too much space in the housing assembly 110 due to its large sliding stroke.

[0050] Optionally, the supporting portion 2112 can also be provided on the bottom wall of the mounting groove 102, while the snap-fit ​​member 141 and the elastic member 142 can also be provided on the fixing base 211. For example, the first surface 2112a can be disposed away from the bottom wall of the mounting groove 102, while the second surface 2112b can be disposed opposite to and spaced apart from the bottom wall of the mounting groove 102. At the same time, the fixing base 211 can be provided with space for the snap-fit ​​member 141 to slide, and the elastic member 142 can be disposed between the snap-fit ​​member 141 and the fixing base 211. The pressing portion 1411 of the snap-fit ​​member 141 can be exposed on the side of the fixing base 211 away from the mounting side 2111 and can slide under the user's actuation, while the hook portion 1412 of the snap-fit ​​member 141 can protrude from the mounting side 2111. With this configuration, when the fixing seat 211 is inserted into the assembly groove 102, the supporting part 2112 can slide against the hook part 1412 through the first surface 2112a to avoid obstruction. After the fixing seat 211 is assembled in place, the hook part 1412 can be reset under the action of elasticity between the second surface 2112b and the bottom wall of the assembly groove 102, and engage with the second surface 2112b to prevent the fixing seat 211 from falling out of the assembly groove 102 from the top surface 1011.

[0051] Optionally, the mounting side 2111 is also provided with a clearance groove 2113, and a portion of the bottom wall of the clearance groove 2113 can be disposed opposite to the second surface 2112b, so that the second surface 2112b can be spaced apart from the mounting side 2111 (fixed seat 211) by means of the clearance groove 2113. When the fixed seat 211 is installed in place, the hook portion 1412 can be inserted into the clearance groove 2113 and slide along the clearance groove 2113 under the action of elasticity to return to the position between the second surface 2112b and the bottom wall of the clearance groove 2113, thereby achieving engagement with the second surface 2112b. This arrangement reduces the stacking height of the hook portion 1412 and the supporting portion 2112 after assembly by means of the clearance groove 2113, thereby reducing the space occupied by the mounting groove 102 on the housing assembly 110.

[0052] Optionally, in order to cooperate with the two hook portions 1412, the mounting base 211 may also be provided with two abutment portions 2112 on the mounting side 2111 and have two clearance grooves 2113, so that the two hook portions 1412 can cooperate with the two abutment portions 2112 respectively, thereby improving the connection between the mounting base 211 and the hook portions 1412.

[0053] Since the assembly slot 102 also extends through the side 1013, in order to prevent the fixing seat 211 from coming off the side 1013 and exiting the assembly slot 102, the fixing seat 211 is also provided with a positioning part 2114 on the mounting side 2111, and a positioning slot 103 is also provided on the bottom wall of the assembly slot 102. Figure 2(As shown). When the fixing base 211 is installed in place, the positioning part 2114 can be inserted into the positioning groove 103 and engage with the side wall of the positioning groove 103 to prevent the fixing base 211 from detaching from the assembly groove 102 on the side 1013. In this embodiment, there are two positioning parts 2114 and two positioning grooves 103, and each positioning part 2114 can cooperate with one of the two positioning grooves 103 to improve the connection stability between the fixing base 211 and the housing assembly 110. Of course, the number of positioning parts 2114 and positioning grooves 103 is not limited to two; this embodiment does not limit this.

[0054] Optionally, the positions of the positioning part 2114 and the positioning groove 103 can be interchanged. That is, the mounting base 211 has a positioning groove 103 on its mounting side 2111, while the mounting groove 102 has a positioning part 2114 on its bottom wall. With this arrangement, when the mounting base 211 is inserted into the mounting groove 102, the positioning part 2114 can still be inserted into the positioning groove 103 and engaged with the side wall of the positioning groove 103, so as to prevent the mounting base 211 from coming off the side 1013 of the mounting groove 102.

[0055] The watch strap 212 is connected to the mounting base 211 and together with the housing assembly 110, forms a wearing space 300 for the user to wear the wearable device 10. To improve the connection between the watch strap 212 and the mounting base 211, the mounting base 211 can be embedded in one end of the watch strap 212, and one end of the watch strap 212 can be simultaneously inserted into the mounting groove 102 along with the mounting base 211. The other end of the watch strap 212 can extend from the side 1013 outside the mounting groove 102. Simultaneously, to facilitate the engagement of the supporting part 2112 and the positioning part 2114 with the hook part 1412 and the positioning groove 103 respectively, the mounting side 2111 can also be exposed outside the watch strap 212. Of course, besides being embedded inside or outside the watch strap 212, the mounting base 211 can also be connected to the watch strap 212 in other ways, such as bonding, welding, or snap-fitting, etc. This embodiment does not limit this method.

[0056] Optionally, when the fixing seat 211 is embedded in one end of the watch strap 212, the mounting side 2111 may not be exposed outside the watch strap 212. In this case, the supporting part 2112 and the positioning part 2114 can pass through the watch strap 212 and protrude from the outside of the watch strap 212, and the watch strap 212 may also have a notch with a communicating clearance groove 2113. With this configuration, the supporting part 2112 and the positioning part 2114 can still cooperate with the hook part 1412 and the positioning groove 103 to achieve a detachable connection between the fixing seat 211 and the hook part 1412.

[0057] Optionally, the clearance groove 2113 may also penetrate the side surface where the fixing seat 211 connects to the mounting side 2111, and this side surface may also be disposed opposite to the side wall of the mounting groove 102 in the sliding direction of the hook portion 1412. The watch strap 212 may also have a connecting portion 2121 extending from the side surface into the clearance groove 2113, and this connecting portion 2121 may occupy a portion of the space in the clearance groove 2113 away from the abutment portion 2112, thereby increasing the contact area between the watch strap 212 and the fixing seat 211, and thus improving the connection strength between the watch strap 212 and the fixing seat 211.

[0058] Please combine Figure 6 and Figure 8 See Figures 9 to 10 , Figure 9 yes Figure 1 A schematic diagram of a partial cross-sectional structure of the wearable device 10 along line V-V. Figure 10 yes Figure 6 A schematic diagram of the structure of the central airbag assembly 220.

[0059] The airbag assembly 220 is mounted on the mounting base 211 and protrudes from the mounting side 2111, allowing the airbag assembly 220 to be simultaneously inserted into the air guide hole 1102 during the process of the mounting base 211 being installed into the assembly slot 102, so as to connect with the air pump assembly 120. Figure 6 and Figures 8 to 9 As shown, the airbag assembly 220 may include an air nozzle 221 and an airbag 222. The air nozzle 221 may protrude from the mounting side 2111 and be inserted into the air guide hole 1102 simultaneously with the mounting base 211 into the mounting groove 102, thus communicating with the air pump assembly 120. The airbag 222 may be connected to and communicate with the air nozzle 221, and the air pump assembly 120 may inflate or deflate the airbag 222 through the air nozzle 221 to control the expansion or contraction of the airbag 222. Simultaneously, the airbag 222 may also be located on the side of the watch strap 212 facing the wearing space 300, so as to facilitate contact with the user's wrist, thereby improving the pressure effect of the inflated airbag 222 on the user's wrist.

[0060] For example, the air nozzle 221 may be disposed on the mounting side 2111, and the air nozzle 221 may include: a main body 2211 and an extension 2212. For example... Figures 8 to 9As shown, the main body 2211 can be provided on the mounting side 2111, and the extension 2212 is provided on the side of the main body 2211 facing away from the mounting side 2111. The extension 2212 is used to connect the airbag 222 and the air duct 1102. For example, the extension 2212 can be inserted into the air duct 1102 simultaneously when it is installed in the mounting slot 102, and has a vent 2212a that connects to the air duct 1102. The vent 2212a can also penetrate the side of the main body 2211 facing the mounting side 2111 and communicate with the airbag 222 located between the main body 2211 and the mounting side 2111.

[0061] Optionally, a sealing ring 223 may be provided on the periphery of the extension 2212 away from the vent 2212a. When the extension 2212 is inserted into the vent 1102, the sealing ring 223 is located between the inner walls of the extension 2212 and the vent 1102, and abuts against both the inner walls of the extension 2212 and the vent 1102 to fill the gap between them, thereby improving the sealing performance of the connection between the extension 2212 and the air pump assembly 120. In this embodiment, the sealing ring 223 may be made of an elastic sealing material such as silicone or rubber.

[0062] Airbag 222 is located on the side of the strap 212 facing the wearing space 300, and airbag 222 also has a vent end 2221 extending to the mounting side 2111. Figures 8 to 10 As shown, the vent end 2221 is located between the main body 2211 and the mounting side 2111, and has a notch 2222 communicating with the vent hole 2212a. The vent end 2221 can connect the airbag 222 and the vent hole 2212a, so that the air pump assembly 120 can inflate and deflate the airbag 222 to control the expansion or contraction of the airbag 222. In this embodiment, the main body 2211 and the vent end 2221 can be connected by high-frequency heat pressing.

[0063] Optionally, a mounting groove 2115 may be provided on the mounting side 2111, and the mounting groove 2115 can be used to accommodate the vent end 2221. The shape of the mounting groove 2115 can be adapted to the shape of the vent end 2221, so that the vent end 2221 can be positioned and connected to the fixing base 211 through the mounting groove 2115, thereby improving the stability of the vent end 2221 on the mounting side 2111.

[0064] Optionally, to cooperate with the two air vents 1102, there can be two air nozzles 221, namely a first air nozzle 221a and a second air nozzle 221b. Similarly, there can also be two vent ends 2221, namely a first vent end 2221a and a second vent end 2221b. Furthermore, there can also be two mounting slots 2115, namely a first mounting slot 2115a and a second mounting slot 2115b. The first vent end 2221a is located within the first mounting slot 2115a and connected to the first air nozzle 221a, and the first vent end 2221a is also in communication with the first air nozzle 221a. The first air nozzle 221a can be inserted into one air vent 1102 when installed in the mounting slot 102. The second vent end 2221b can be located in the second mounting groove 2115b and connected to the second air nozzle 221b. The second vent end 2221b is connected to the second air nozzle 221b, and the second air nozzle 221b can be inserted into another air guide hole 1102 when it is installed in the assembly groove 102.

[0065] Alternatively, the design of the vent 2221 can be omitted. In this case, a portion of the main body 2211 can extend toward the side of the strap 212 located within the wearing space 300, and has an air channel connecting to the vent 2212a. The airbag 222 can be directly connected to the area of ​​the main body 2211 extending to the side of the strap 212 located within the wearing space 300, and connected to the air channel to achieve communication between the airbag 222 and the air nozzle 221.

[0066] Alternatively, the airbag 222 can be located on the side of the strap 212 facing the wearing space 300, or it can be embedded within the strap 212. In this case, the airbag 222 can still communicate with the air nozzle 221 through the vent end 2221 extending to the mounting side 2111. Meanwhile, the strap 212 is preferably made of an elastic material and has a certain amount of redundant space to avoid restricting the inflation of the airbag 222.

[0067] Please combine Figure 6 and Figure 9 See Figures 11 to 12 , Figure 11 yes Figure 6 A schematic diagram of the cross-sectional structure of the middle section of the watch strap mechanism 200 along line IV-IV. Figure 12 yes Figure 6 A schematic diagram of the structure of the middle fixing plate 213.

[0068] Exemplarily, the watchband assembly 210 may further include a fixing plate 213, which can be used to fix the air nozzle 221 and the vent end 2221 to the mounting side 2111. Figure 6 and Figures 11 to 12As shown, the fixing plate 213 can be covered on the mounting side 2111 and is located on the side of the main body 2211 facing away from the mounting side 2111. It can be configured to clamp the main body 2211 and the vent end 2221 together with the fixing base 211. The extension 2212 can pass through the fixing plate 213 and protrude from the side of the fixing plate 213 facing away from the mounting side 2111. The mounting side 2111 can be provided with screw holes. The fixing plate 213 can be locked to the mounting side 2111 by bolts that pass through the fixing plate 213 and are inserted into the screw holes, so that it can clamp the main body 2211 and the vent end 2221 together with the fixing base 211.

[0069] Optionally, the fixing plate 213 may also be provided with a limiting part 2131 located in the mounting groove 2115, and a limiting groove 2116 that cooperates with the limiting part 2131 may also be provided on the side wall of the mounting groove 2115. The limiting part 2131 can be inserted into the limiting groove 2116 and engaged with the inner wall of the limiting groove 2116 to improve the connection stability between the fixing plate 213 and the fixing base 211.

[0070] For example, the fixing plate 213 may include a connecting portion 2132, a first fixing portion 2133, and a second fixing portion 2134. The connecting portion 2132 is located between the first air nozzle 221a and the second air nozzle 221b, and can be bolted to the mounting side 2111. The first fixing portion 2133 and the second fixing portion 2134 are respectively connected to opposite sides of the connecting portion 2132. The first fixing portion 2133, together with the fixing base 211, clamps the first air nozzle 221a and the first venting end 2221a, while the second fixing portion 2134, together with the fixing base 211, clamps the second air nozzle 221b and the second venting end 2221b. Meanwhile, the first mounting groove 2115a and the second mounting groove 2115b are provided with limiting grooves 2116 on their sidewalls away from each other, and the first fixing part 2133 and the second fixing part 2134 are provided with limiting parts 2131 on their side away from each other. The two limiting parts 2131 can be respectively inserted into the two limiting grooves 2116 to improve the connection stability between the fixing plate 213 and the fixing seat 211.

[0071] Alternatively, the design of the fixing plate 213 can be omitted. The vent end 2221 and the air nozzle 221 can also be fixed in the mounting groove 2115 by other methods such as welding, snap-fitting or bonding, which is not limited in this embodiment.

[0072] Optionally, in addition to creating a mounting groove 102 on the top surface 1011, a mounting groove 102 can also be created on the bottom surface 1012, allowing the mounting base 211 to be inserted into the mounting groove 102 from the bottom surface 1012, thereby increasing the usable area (e.g., display area) of the top surface 1011. In the structure of the aforementioned embodiment, if the mounting base 211 is inserted into the mounting groove 102 from the bottom surface 1012, the airbag 222 will be located on the side of the watch strap 212 away from the wearing space, which is not conducive to the airbag 222 inflating and pressing on the user's wrist. Based on this, in this embodiment, the airbag 222 is preferably embedded in the watch strap 212, and the vent end 2221 of the airbag 222 still extends to the mounting side 2111 of the mounting base 211 facing the bottom wall of the mounting groove 102, so as to communicate with the air nozzle 221. Similarly, the fixing plate 213 can still be placed on the mounting side 2111 to lock the vent end 2221 and the air nozzle 221 onto the fixing base 211. With this configuration, when the fixing base 211 is inserted into the mounting groove 102 from the bottom surface 1012, the extension 2212 of the air nozzle 221 can still be inserted into the air duct 1102 to communicate with the air pump assembly 120. Furthermore, to reduce the restriction caused by the watch strap 212 on the inflation of the airbag 222, the watch strap 212 is preferably made of an elastic material and has a certain amount of redundant space to allow for the inflation of the airbag 222.

[0073] The wearable device 10 provided in this application, by placing the airbag assembly 220 on the strap assembly 210, and when the strap assembly 210 is detachably connected to the watch head mechanism 100 by being inserted into the mounting slot 102, the airbag assembly 220 can also be inserted into the mounting slot 102 along with the strap assembly 210 and communicate with the watch head mechanism 100. This allows the airbag assembly 220 to be fixed using the detachable connection between the strap assembly 210 and the watch head mechanism 100, thus maintaining the communication between the airbag assembly 220 and the watch head mechanism 100. With this configuration, the wearable device 10 can reuse the detachable connection between the strap assembly 210 and the watch head mechanism 100, allowing the watch head mechanism 100 to omit the structure required to fix the airbag assembly 220, thereby increasing the available space in the watch head mechanism 100 and reducing the limitations imposed on the design and internal component layout of the watch head mechanism 100 due to insufficient space.

[0074] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application.
