[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 occupies part of the space of 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.

[0020] 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.

[0021] 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.

[0022] See also Figures 1 to 3 , 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 The structural diagram of the middle header mechanism 100, Figure 3 yes Figure 1 Schematic diagram of the partial cross-sectional structure of the middle header mechanism 100 along V-V.

[0023] The wearable device 10 provided in the present application may be a smart watch, a smart bracelet, or a cuff-type blood pressure measuring device, etc., and the following only takes the wearable device 10 as a smart watch as an example. Figure 1 As shown, the wearable device 10 includes: a watch head mechanism 100 and a watch strap mechanism 200. The watch head mechanism 100 is detachably connected to the watch strap mechanism 200, and can be enclosed together with the watch strap mechanism 200 to form a wearing space 300, and the user can wear the watch head mechanism 100 and the watch strap mechanism 200 on the wrist through the wearing space 300. At the same time, the watch head mechanism 100 is also connected to the watch strap mechanism 200, and can control the watch strap mechanism 200 to expand or contract, and the watch strap mechanism 200 can also compress the blood vessels in the user's wrist after expansion to cooperate with the watch head mechanism 100 to measure the user's blood pressure. In this embodiment, the detachable connection and communication of the watch head mechanism 100 and the watch strap mechanism 200 can be realized simultaneously, so that the watch head mechanism 100 can omit the structure required for maintaining communication with the watch head mechanism 100, so as to increase the available space of the watch head mechanism 100, thereby reducing the restrictions on the shape design and internal device layout of the watch head mechanism 100 due to insufficient space.

[0024] For example, the watch head mechanism 100 is detachably connected to the watch strap mechanism 200, and can control the watch strap mechanism 200 to expand or contract, so as to cooperate with the watch strap mechanism 200 to achieve the blood pressure measurement function. Figures 2 to 3 As shown, the watch head mechanism 100 has an assembly surface 101 in the thickness direction Z, and an assembly groove 102 is provided on the assembly surface 101. The strap mechanism 200 can be installed into the assembly groove 102 from the assembly surface 101, and can be detachably connected and communicated with the watch head mechanism 100 at the same time. The assembly 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 be provided with an assembly groove 102, and the strap mechanism 200 is installed into the assembly groove 102 from one of the top surface 1011 and the bottom surface 1012 that has the assembly groove 102. At the same time, the watch header mechanism 100 also has a side surface 1013 respectively connecting the top surface 1011 and the bottom surface 1012, and the assembly groove 102 can also penetrate the side surface 1013 to avoid the strap mechanism 200 when the strap mechanism 200 is installed in the assembly groove 102, thereby improving the integrated effect of the watch header mechanism 100 and the strap mechanism 200 in appearance.

[0025] Optionally, the assembly groove 102 may not penetrate the side surface 1013. In this case, the strap mechanism 200 can be assembled on one of the top surface 1011 and the bottom surface 1012 with the assembly groove 102, and a matching structure protruding from the assembly groove 102 is provided to communicate with the watch head mechanism 100 and be detachably connected.

[0026] When the watch head mechanism 100 and the watch strap mechanism 200 are jointly arranged to form the wearing space 300, the top surface 1011 can be specifically the side of the watch head mechanism 100 away from the wearing space 101, and when the watch head mechanism 100 has a display function, part of the top surface 1011 can also be used as the display surface of the watch head mechanism 100 for the user to watch. At the same time, the bottom surface 1012 can be specifically the side of the watch head mechanism 100 facing the wearing space 101, and can contact the user's wrist, and when the watch head mechanism 100 has a heart rate detection function (such as equipped with an ECG or PPG module), the bottom surface 1012 can also be used as the electrode contact surface or light-emitting surface of the watch head mechanism 100 to obtain the user's biological information. The following is only an example in which the top surface 1011 is provided with an assembly groove 102, and the assembly groove 102 also passes through the side surface 1013.

[0027] like Figures 2 to 3 As shown, the meter head 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 that are arranged opposite to each other in the thickness direction Z, and a side surface 1013 that connects the top surface 1011 and the bottom surface 1012 respectively, and the housing assembly 110 has the aforementioned assembly groove 102. At the same time, the housing assembly 110 also has a receiving space 1101, and the receiving space 1101 can be used to install the air pump assembly 120 and other functional components required by the meter head mechanism 100, such as a battery, a microphone, a speaker, a pressure sensor, an ECG module, and a PPG module. In addition, the shell component 110 is also provided with an air guide hole 1102 on the bottom wall of the assembly groove 102, which is connected to the accommodating space 1101, and the air guide hole 1102 can be used to achieve the connection between the air pump component 120 and the strap mechanism 200, so that the air pump component 120 can inflate and deflate the strap mechanism 200 through the air guide hole 1102 to control the expansion or contraction of the strap mechanism 200.

[0028] Exemplarily, the housing assembly 110 may include: a frame 111 and a back cover 112. The frame 111 may be arranged to enclose a receiving space 1101, and the back cover 112 may be arranged to cover a side of the receiving space 1101 where an opening is formed on the frame 111, and close the receiving space 1101. At the same time, a side of the frame 111 facing away from the back cover 112 may be used to form a top surface 1011, and a side of the back cover 112 facing away from the frame 111 may be used to form a bottom surface 1012, and a side of the frame 111 facing away from the receiving space 1101 may be a side surface 1013 respectively connecting the top surface 1011 and the bottom surface 1012. In this embodiment, the frame 111 may be provided with the aforementioned assembly groove 102, and the aforementioned air guide hole 1102 may be provided on the bottom wall of the assembly groove 102.

[0029] The air outlet structure of the air pump assembly 120 can be inserted into the air guide hole 1102, and the strap mechanism 200 can also be inserted into the air guide hole 1102 after being installed in the assembly slot 102, so that the air pump assembly 120 and the strap mechanism 200 can be connected by using the air guide hole 1102. Similarly, the air pump assembly 120 and the strap mechanism 200 can also be inserted into the air guide structure of the frame 111 to form the air guide hole 1102, so as to realize the connection between the air pump assembly 120 and the strap mechanism 200 by using the air guide hole 1102. In this embodiment, the strap mechanism 200 is preferably connected with the air guide hole 1102 by insertion or being inserted, so as to simplify the steps required for connecting the strap mechanism 200 with the air guide hole 1102, which is conducive to improving the convenience of the strap mechanism 200 being detachably connected and connected with the watch head mechanism 100 at the same time, and the air pump assembly 120 and the air guide hole 1102 can also be connected by other methods, which is not limited in this embodiment.

[0030] The number of the air guide holes 1102 can also be two, and the two air guide holes 1102 can be opened at intervals on the bottom wall of the assembly slot 102, and both are connected to the air pump assembly 120. When the strap mechanism 200 is installed in the assembly slot 102, the strap mechanism 200 can be inserted into the two air guide holes 1102 simultaneously, and the air pump assembly 120 can inflate and deflate the strap mechanism 200 through the two air guide holes 1102 to control the expansion or contraction of the strap mechanism 200. Of course, the number of the air guide holes 1102 may not be limited to two, and the number of the air guide holes 1102 may also be adaptively adjusted according to design requirements, which is not limited in this embodiment.

[0031] When the header mechanism 100 has a display function, the header mechanism 100 may further include: a display assembly 130. The storage space 1101 may pass through the opposite sides of the frame 111, the back cover 112 may be covered on one side of the storage space 1101 where an opening is formed on the frame 111, and the display assembly 130 may be covered on the other opposite side of the storage space 1101 where an opening is formed on the frame 111, so that the back cover 112 and the display assembly 130 may be jointly enclosed with the frame 111 to form a closed storage space 1101. At the same time, the display assembly 130 and the side of the frame 111 facing away from the back cover 112 may jointly form a top surface 1011, and the side of the back cover 112 facing away from the frame 111 may be used to form a bottom surface 1012, and the side of the frame 111 facing away from the storage space 1101 may be a side surface 1013 respectively connecting the top surface 1011 and the bottom surface 1012. In this embodiment, a partial area of ​​the top surface 1011 corresponding to the display component 130 can be used as a display surface, and a partial area of ​​the top surface 1011 corresponding to the frame 111 can be provided with an assembly groove 102, and the assembly groove 102 is preferably provided at the edge of the top surface 1011 away from the display component 130.

[0032] It can be understood that the above-mentioned embodiment in which the shell assembly 110 includes a frame 111 and a back cover 112 is an exemplary description, and the specific structure of the shell assembly 110 can also be adjusted or changed according to design requirements, and is not limited to including a frame 111 and a back cover 112. It is only necessary for the shell assembly 110 to have a top surface 1011, a bottom surface 1012 and a side surface 1013, and to be provided with an assembly groove 102 and an air guide hole 1102. This embodiment is not limited to this.

[0033] Please combine Figure 2 See also Figures 4 to 5 , Figure 4 yes Figure 1 A schematic diagram of a partial cross-sectional structure of the middle header mechanism 100 along VI-VI, Figure 5 yes Figure 4 A schematic structural diagram of the middle clamping member 141.

[0034] In order to realize the detachable connection between the watch head mechanism 100 and the watch band mechanism 200, the watch head mechanism 100 may further include a sliding assembly 140. Figure 2 and Figure 4As shown, the sliding assembly 140 is slidably connected with the housing assembly 110 and exposed on the bottom surface 1012, and the sliding assembly 140 is also protruded from the bottom wall of the assembly groove 102. When the strap mechanism 200 is installed in the assembly groove 102, the strap mechanism 200 can push the sliding assembly 140 to slide and avoid, so that the strap mechanism 200 can be installed in the assembly groove 102. After the strap mechanism 200 is installed in place, the sliding assembly 140 can be reset and engaged with the strap mechanism 200 to prevent the strap mechanism 200 from escaping from the assembly groove 102 on the top surface 1011. At the same time, the user can also press the sliding assembly 140 from the bottom surface 1012 to slide, and the sliding assembly 140 can release the engagement with the strap mechanism 200 after being pressed and sliding, so that the strap mechanism 200 can be escaping from the assembly groove 102 on the top surface 1011. With such arrangement, when the strap mechanism 200 is inserted into the assembly slot 102 , the sliding assembly 140 can cooperate with the strap mechanism 200 to achieve a detachable connection between the watch head mechanism 100 and the strap mechanism 200 .

[0035] Exemplarily, the sliding assembly 140 includes: a clamping member 141 and an elastic member 142. Figure 2 and Figure 4 As shown, the clamping member 141 is slidably connected with the housing assembly 110 and exposed on the bottom surface 1012, and the clamping member 141 is also protruded from the bottom wall of the assembly groove 102. The elastic member 142 is arranged between the clamping member 141 and the housing assembly 110, and is located on the sliding path of the clamping member 141. When the strap mechanism 200 is installed into the assembly groove 102, the strap mechanism 200 can push the clamping member 141 to slide and avoid, and the clamping member 141 can also press the elastic member 142 to elastically deform. When the strap mechanism 200 is installed in place, the clamping member 141 can be reset under the elastic force provided by the elastic member 142 and be clamped with the strap mechanism 200. At the same time, the user can also press the clamping member 141 from the bottom surface 1012 to slide, and the clamping member 141 can release the clamping connection with the strap mechanism 200 after being pressed and slid, and press the elastic member 142 to elastically deform, so that the elastic force of the elastic member 142 can be used to reset the strap mechanism 200 after it escapes from the assembly groove 102. In this way, the clamping member 141 can be reset by the elastic force of the elastic member 142 after being pushed or pressed to slide, so as to achieve a detachable connection with the watch head mechanism 100.

[0036] The housing assembly 110 has a sliding space 1103 for installing the clamping member 141. Figure 4As shown, the side of the frame 111 away from the bottom wall of the assembly slot 102 can be enclosed together with the edge area of ​​the back cover 112 to form a sliding space 1103, and 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 assembly slot 102 respectively. Among them, the clamping member 141 can be arranged in the sliding space 1103, and the clamping member 141 can also be exposed on the bottom surface 1012 through the first opening 1103a, so that the user can press the clamping member 141 on the bottom surface 1012. At the same time, the clamping member 141 can also protrude from the bottom wall of the assembly slot 102 through the second opening 1103b, so as to cooperate with the strap mechanism 200 for detachable connection when the strap mechanism 200 is installed in the assembly slot 102.

[0037] The clamping member 141 includes a pressing portion 1411 and a hook portion 1412. Figure 4 and Figure 5 As shown, the pressing portion 1411 is arranged in the sliding space 1103 and exposed on the bottom surface 1012 through the first opening 1103a, and the pressing portion 1411 can be pressed by the user. At the same time, the pressing portion 1411 is also provided with a fixing column 14111, and one end of the elastic member 142 can be sleeved on the fixing column 14111 to achieve the connection between the elastic member 142 and the clamping member 141. The hook portion 1412 is connected to the pressing portion 1411 and protrudes from the bottom wall of the assembly groove 102 through the second opening 1103b. Among them, when the strap mechanism 200 is installed in the assembly groove 102, the strap mechanism 200 can push the hook portion 1412 to slide to avoid, and drive the pressing portion 1411 to slide against the elastic member 142. When the strap mechanism 200 is installed in place, the hook portion 1412 can be reset under the elastic force of the elastic member 142 and be engaged with the strap mechanism 200. Similarly, when the user presses the pressing portion 1411, the pressing portion 1411 can drive the hook portion 1412 to slide and press the elastic member 142 to cause elastic deformation, so that the hook portion 1412 is released from the engagement with the strap mechanism 200.

[0038] Optionally, the side of the pressing portion 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 is formed with a first opening 1103a at the edge area where the bottom surface 1012 and the side surface 1013 meet. With such a configuration, compared with the solution in which the pressing portion 1411 is exposed on the bottom surface 1012 by penetrating the back cover 112, the step of assembling the pressing portion 1411 and the back cover 112 can be omitted, thereby improving the convenience of assembling the clamping member 141 and the housing assembly 110.

[0039] Optionally, the sliding space 1103 may be formed with two second openings 1103b on the bottom wall of the assembly groove 102, and the clamping member 141 may be provided with two hook portions 1412. Figure 2 and Figure 5 As shown, the two second openings 1103b can be arranged at intervals, and the two hook portions 1412 can be connected to the same side of the pressing portion 1411 at intervals. The two hook portions 1412 can be respectively arranged to protrude from the bottom wall of the assembly groove 102 through the two second openings 1103b, and the two hook portions 1412 can cooperate with the strap mechanism 200 to achieve a detachable connection between the watch header mechanism 100 and the watch strap mechanism 200. In this way, the two hook portions 1412 cooperate with the strap mechanism 200, which is conducive to improving the connection stability between the watch header mechanism 100 and the strap mechanism 200. It can be understood that the cooperation between the two hook portions 1412 and the watch header mechanism 100 is the same or similar to that in the above-mentioned embodiment, and this embodiment will not be repeated.

[0040] The housing assembly 110 also has a receiving hole 1104 for mounting the elastic member 142. Figure 4 As shown, the frame 111 is located at one side of the sliding space 1103, that is, the inner wall of the sliding space 1103 is provided with a receiving hole 1104 connected to the receiving space 1101, and the housing assembly 110 is also provided with a baffle 113 located in the receiving space 1101 and covering the receiving hole 1104. Among them, the elastic member 142 can be arranged in the receiving hole 1104, and the opposite ends of the elastic member 142 can be connected to the baffle 113 and the clamping member 141 respectively, and can be elastically deformed by the baffle 113 and the clamping member 141 after the clamping member 141 slides, so as to provide elastic force to drive the clamping member 141 to reset. In this embodiment, the receiving hole 1104 can be formed by opening from one side of the frame 111 located in the receiving space 1101, and the baffle 113 is used to cover the receiving hole 1104 and play a role in supporting the elastic member 142. Compared with providing the receiving hole 1104 on the inner wall of the sliding space 1103 , such a configuration is helpful to reduce the difficulty of processing the receiving hole 1104 .

[0041] Optionally, the elastic member 142 can specifically be a spring. Of course, in addition to the spring, the elastic member 142 can also be other structural members that can generate elastic force. For example, the elastic member 142 can also be composed of elastic materials such as rubber or silicone filled in the receiving hole 1104, and the fixing column 14111 can be inserted in the receiving hole 1104. Among them, when the clamping member 141 slides, the fixing column 14111 can press the elastic member 142 to cause the elastic member 142 to undergo elastic deformation, thereby providing elastic force to drive the clamping member 141 to reset. At the same time, the fixing column 14111 is inserted in the receiving hole 1104, and can also cooperate with the inner wall of the receiving hole 1104 to provide a guiding effect for the sliding of the clamping member 141, so as to improve the sliding consistency of the clamping member 141. It is understandable that when the elastic member 142 is a spring, the fixing column 14111 can also be inserted into the receiving hole 1104 so that the fixing column 14111 can press the elastic member 142 to cause elastic deformation.

[0042] The watch head mechanism 100 provided in the embodiment of the present application, by providing a hook portion 1412 on the bottom wall of the assembly slot 102, and opening an air guide hole 1102 connected to the air pump assembly 120 on the bottom wall of the assembly slot 102, enables the strap mechanism 200 to be synchronously matched with the hook portion 1412 and the air guide hole 1102 when it is installed into the assembly slot 102 from the top surface 1011, so as to simultaneously realize the connection and detachable connection between the strap mechanism 200 and the watch head mechanism 100. With such a configuration, the watch head mechanism 100 can omit the structure on the housing assembly 110 for fixing the connection between the strap mechanism 200 and the air guide hole 1102, so as to increase the available space of the watch head mechanism 100, thereby reducing the restrictions on the shape design and internal device layout of the watch head mechanism 100 due to insufficient space. In addition, the omission and simplification of the structure of the watch head mechanism 100 can also play a role in reducing material costs and assembly costs.

[0044] The strap mechanism 200 is inserted into the assembly groove 102 from the top surface 1011 and inserted into the air guide hole 1102, and the strap mechanism 200 can also be detachably connected to the hook portion 1412. Figure 6As shown, the strap mechanism 200 includes: a strap assembly 210 and an airbag assembly 220. The strap assembly 210 can be installed into the assembly slot 102 from the top surface 1011 and detachably connected to the hook portion 1412. The airbag assembly 220 is arranged on the strap assembly 210, and can be synchronously inserted into the air guide hole 1102 during the process of the strap assembly 210 being installed into the assembly slot 102, so as to communicate with the air pump assembly 120. The air pump assembly 120 can inflate and deflate the airbag assembly 220 through the air guide hole 1102 to control the expansion or contraction of the airbag assembly 220.

[0045] Through the above arrangement, since the airbag assembly 220 can be inserted into the air guide hole 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 play a fixing role in the connection between the airbag assembly 220 and the air pump assembly 120, so that the header mechanism 100 can omit the structure set on the shell assembly 110 for fixing the airbag assembly 220, so as to increase the available space on the shell assembly 110, thereby reducing the restrictions on the shape design and internal device layout of the header mechanism 100 due to insufficient space. In addition, compared with the solution in which the airbag assembly 220 is independently fixed to the header mechanism 100, the user only needs one operation to simultaneously complete the disassembly and assembly of the strap assembly 210 and the airbag assembly 220 from the header mechanism 100, which is conducive to improving the convenience of users in disassembling and assembling the strap mechanism 200.

[0046] Exemplarily, the strap assembly 210 includes: a fixing seat 211 and a strap 212. Figure 6 to Figure 7 As shown, the fixing seat 211 can be installed into the assembly groove 102 from the top surface 1011, and is detachably connected to the hook portion 1412, and the fixing seat 211 is also connected to the airbag assembly 220, so that the airbag assembly 220 can be installed into the assembly groove 102 with the fixing seat 211 to be inserted into the air guide hole 1102, thereby achieving communication with the air pump assembly 120. The strap 212 can be connected to the fixing seat 211, and can be enclosed together with the housing assembly 110 to form the aforementioned wearing space 300, and the airbag assembly 220 is also located on the side of the 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 pressing the user's wrist.

[0047] The fixing seat 211 has a mounting side 2111 disposed toward the bottom wall of the assembly slot 102, and a supporting portion 2112 is disposed on the mounting side 2111, and the supporting portion 2112 is used to be detachably connected to the hook portion 1412. Figures 7 and 8As shown, the abutting portion 2112 may be arranged protruding from the mounting side 2111, and may have a first surface 2112a and a second surface 2112b arranged opposite to each other, and the first surface 2112a may be arranged away from the mounting side 2111, while the second surface 2112b may be arranged opposite to and spaced from the mounting side 2111. When the fixing seat 211 is installed in the assembly slot 102, the first surface 2112a of the abutting portion 2112 may contact the hook portion 1412, and push the hook portion 1412 to slide and avoid. When the fixing seat 211 is installed in place, the first surface 2112a can be separated from the hook portion 1412, so that the hook portion 1412 can be reset under the action of elastic force and reset to between the second surface 2112b and the installation side 2111, and the hook portion 1412 can also be engaged with the second surface 2112b to prevent the fixing seat 211 from slipping out of the assembly groove 102 on the top surface 1011. In addition, when the user presses the pressing portion 1411, the hook portion 1412 can also slide out of the area between the second surface 2112b and the installation side 2111 under the drive of the pressing portion 1411 to release the engagement with the second surface 2112b, so that the fixing seat 211 can slip out of the top surface 1011.

[0048] Optionally, the first surface 2112a may be an inclined surface, so that the fixing seat 211 can push the hook portion 1412 to slide through the first surface 2112a. At the same time, the hook portion 1412 may also be provided with a matching surface parallel to the first surface 2112a, and the first surface 2112a may contact the hook portion 1412 through the matching surface to push the hook portion 1412 to slide.

[0049] Optionally, in order to reduce the sliding stroke of the hook portion 1412, the abutting 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 installed in the assembly groove 102, the hook portion 1412 may contact the first surface 2112a, and in the process of being pushed by the first surface 2112a, slide from the first surface 2112a to the third surface 2112c, and the third surface 2112c may only abut against the hook portion 1412 to keep the hook portion 1412 pressing the elastic member 142. When the fixing seat 211 is installed in place, the hook portion 1412 may be separated from the third surface 2112c, so that the hook portion 1412 can be reset to between the second surface 2112b and the installation side 2111 under the action of elastic force to engage with the second surface 2112b. Compared with the hook portion 1412 directly transitioning 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 more space in the housing assembly 110 due to the large sliding stroke.

[0050] Optionally, the abutting portion 2112 may also be arranged on the bottom wall of the assembly groove 102, and the clamping member 141 and the elastic member 142 may also be arranged on the fixing seat 211. For example, the first surface 2112a may be arranged away from the bottom wall of the assembly groove 102, and the second surface 2112b may be arranged opposite to and spaced from the bottom wall of the assembly groove 102. At the same time, a space for the clamping member 141 to slide may be provided on the fixing seat 211, and the elastic member 142 may be arranged between the clamping member 141 and the fixing seat 211. Among them, the pressing portion 1411 of the clamping member 141 may be exposed on the side of the fixing seat 211 away from the installation side 2111, and may slide under the user's manipulation, and the hook portion 1412 of the clamping member 141 may be arranged protruding from the installation side 2111. With such a configuration, when the fixing seat 211 is installed in the assembly groove 102, the abutting portion 2112 can slide and avoid the hook portion 1412 by pushing the first surface 2112a. When the fixing seat 211 is assembled in place, the hook portion 1412 can be reset to between the second surface 2112b and the bottom wall of the assembly groove 102 under the action of elastic force, and be engaged with the second surface 2112b to prevent the fixing seat 211 from slipping out of the assembly groove 102 from the top surface 1011.

[0051] Optionally, the installation side 2111 is also provided with an escape groove 2113, and part of the bottom wall of the escape groove 2113 can be arranged opposite to the second surface 2112b, so that the second surface 2112b can be spaced apart from the installation side 2111 (fixed seat 211) by utilizing the escape groove 2113. When the fixed seat 211 is installed in place, the hook portion 1412 can be inserted into the escape groove 2113, and slide along the escape groove 2113 under the action of elastic force to reset to between the second surface 2112b and the bottom wall of the escape groove 2113, thereby realizing the engagement with the second surface 2112b. With such an arrangement, the escape groove 2113 can be used to reduce the stacking height of the hook portion 1412 and the abutting portion 2112 after assembly, thereby reducing the space occupied by the assembly groove 102 on the housing assembly 110.

[0052] Optionally, in order to cooperate with the two hook portions 1412, the fixing seat 211 may also be provided with two abutting portions 2112 on the mounting side 2111, and two avoidance grooves 2113 may be provided, so that the two hook portions 1412 can respectively cooperate with the two abutting portions 2112 to improve the connection firmness between the fixing seat 211 and the hook portion 1412.

[0053] Since the assembly groove 102 also penetrates the side surface 1013, in order to prevent the fixing seat 211 from falling out of the assembly groove 102 from the side surface 1013, the fixing seat 211 is further provided with a positioning portion 2114 on the installation side 2111, and the bottom wall of the assembly groove 102 is further provided with a positioning groove 103 ( Figure 2). When the fixing seat 211 is installed in place, the positioning portion 2114 can be inserted into the positioning groove 103 and snap-fitted with the side wall of the positioning groove 103 to prevent the fixing seat 211 from slipping out of the assembly groove 102 from the side 1013. In this embodiment, the number of the positioning portion 2114 and the positioning groove 103 are both two, and the two positioning portions 2114 can respectively cooperate with the two positioning grooves 103 to improve the connection stability between the fixing seat 211 and the housing assembly 110. Of course, the number of the positioning portion 2114 and the positioning groove 103 may not be limited to two, and this embodiment does not limit this.

[0054] Optionally, the positions of the positioning portion 2114 and the positioning groove 103 can also be interchanged. That is, the fixing seat 211 is provided with a positioning groove 103 on the installation side 2111, and the bottom wall of the assembly groove 102 is provided with a positioning portion 2114. In this way, when the fixing seat 211 is installed in the assembly groove 102, the positioning portion 2114 can still be inserted into the positioning groove 103 and snap-fit ​​with the side wall of the positioning groove 103 to prevent the fixing seat 211 from slipping out of the assembly groove 102 from the side 1013.

[0055] The strap 212 is connected to the fixing seat 211, and can be enclosed together with the shell assembly 110 to form a wearing space 300 for the user to wear the wearable device 10. In order to improve the connection firmness between the strap 212 and the fixing seat 211, the fixing seat 211 can be embedded in one end of the strap 212, and one end of the strap 212 can be installed in the assembly slot 102 synchronously with the fixing seat 211, while the other end of the strap 212 can extend from the side 1013 to the outside of the assembly slot 102. At the same time, in order to facilitate the cooperation between the abutting portion 2112 and the positioning portion 2114 with the hook portion 1412 and the positioning slot 103 respectively, the installation side 2111 can also be exposed outside the strap 212. Of course, in addition to being embedded inside and outside the strap 212, the fixing seat 211 can also be connected to the strap 212 in other ways, such as bonding, welding or clamping, etc., which is not limited in this embodiment.

[0056] Optionally, when the fixing seat 211 is embedded in one end of the strap 212, the mounting side 2111 may not be exposed outside the strap 212. In this case, the abutting portion 2112 and the positioning portion 2114 may be inserted through the strap 212 and protrude from the strap 212, and the strap 212 may also be provided with a notch connected to the avoidance groove 2113. In this way, the abutting portion 2112 and the positioning portion 2114 may still cooperate with the hook portion 1412 and the positioning groove 103 to achieve a detachable connection between the fixing seat 211 and the hook portion 1412.

[0057] Optionally, the avoidance groove 2113 may also penetrate the side surface of the fixing seat 211 connected to the installation side 2111, and the side surface may also be arranged opposite to the side wall of the assembly groove 102 in the sliding direction of the hook portion 1412. The strap 212 may also be provided with a coupling portion 2121 extending from the side surface to the avoidance groove 2113, and the coupling portion 2121 may occupy a part of the space of the avoidance groove 2113 away from the abutting portion 2112, so as to increase the contact area between the strap 212 and the fixing seat 211, thereby improving the connection firmness between the strap 212 and the fixing seat 211.
