Description

Wearable devices, watch heads and housing components

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on July 17, 2023, with application number 2023108778513 and invention name “Wearable device, watch head mechanism and shell assembly”, the entire contents of which are incorporated by reference into this application.

Technical field

[0002] The present application relates to the technical field of wearable devices, and in particular to a wearable device, a watch head mechanism, and a housing assembly. [Background Technology]

[0003] At present, the common blood pressure measurement solution for 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 inside 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 components.

[0004] [Summary of the invention]

[0005] On one hand, the present application provides a wearable device, which includes: a strap mechanism and a head mechanism, and the head mechanism includes: a shell assembly and an air pump assembly arranged in the shell assembly; wherein the shell assembly is provided with an air path connecting the air pump assembly and the outside of the shell assembly, the strap mechanism is detachably connected to the shell assembly, and is synchronously connected to the air path when detachably connected to the shell assembly; the air pump assembly is configured to inflate and deflate the strap mechanism through the air path.

[0006] On the other hand, the present application provides a watch header mechanism for connecting to a watch strap mechanism, the watch header mechanism comprising: a shell assembly and an air pump assembly arranged in the shell assembly; wherein the shell assembly is provided with an air path connecting the air pump assembly and the outside of the shell assembly, the watch strap mechanism is detachably connected to the shell assembly, and is synchronously connected to the air path when detachably connected to the shell assembly; the air pump assembly is configured to inflate and deflate the watch strap mechanism through the air path.

[0007] The present application also provides a shell assembly for connecting a strap mechanism and accommodating an air pump assembly, the shell assembly comprising: a frame, and the frame comprising: a frame portion surrounding an installation space, and a ventilation portion connected to the frame portion and located in the installation space; the air pump assembly is located in the installation space, and a connecting hole is provided on a side of the frame portion facing away from the installation space; the strap mechanism is detachably connected to a side of the frame portion facing away from the installation space, and is synchronously inserted into the connecting hole when connected to the frame portion; the ventilation portion has a ventilation space connecting the connecting hole and the air pump assembly, and the ventilation space and the connecting hole together constitute an air path, and the air pump assembly is configured to inflate and deflate the strap mechanism through the air path.

[0008] The wearable device provided by the present application has an air path on the housing assembly that connects the air pump assembly and the outside of the housing assembly. The air path can also be connected to the strap mechanism when the housing assembly and the strap mechanism are detachably connected. This allows the detachable connection between the housing assembly and the strap mechanism to also secure the connection between the strap mechanism and the air path. With this arrangement, the fixing structure required for maintaining the connection between the strap mechanism and the air path on the housing assembly can be omitted, thereby increasing the available space for the header mechanism and reducing the limitations on the design of the header mechanism and the layout of internal components due to insufficient space.

[0055] The present application will be further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only intended to illustrate the present application and are not intended to limit the scope of the present application. Similarly, the following examples are only some examples of the present application and not all examples. All other examples obtained by those of ordinary skill in the art without creative work are intended to fall within the scope of protection of this application.

[0056] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0057] Please refer to Figures 1 and 2. Figure 1 is a partial structural diagram of a wearable device 10 provided in an embodiment of the present application, and Figure 2 is a structural diagram of the strap mechanism 100 in Figure 1.

[0058] The wearable device 10 provided in this application can be a smart watch, a smart bracelet, or a cuff-type blood pressure measuring device, etc., and the following only uses the wearable device 10 as an example of a smart watch. As shown in Figure 1, the wearable device 10 includes: a strap mechanism 100 and a header mechanism 200. Among them, 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 limitations on the shape design and internal device layout of the header mechanism 200 due to insufficient space.

[0059] The strap mechanism 100 can be detachably connected to the header mechanism 200 and can expand or contract under the control of the header mechanism 200. As shown in Figure 2, 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. 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 component 120 can also synchronously connect the strap component 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 component 110 through the connecting component 120 to achieve expansion or contraction of the strap component 110.

[0060] The inventors have discovered that, in addition to being provided with a structure for detachably connecting with the strap assembly 110, the watch header mechanism 200 in the related solution also includes a structure for fixing the inflation and deflation interface of the strap assembly 110. For example, the watch header mechanism 200 includes a groove for mounting the inflation and deflation interface, and a position-limiting cover for securing the inflation and deflation interface within the groove. However, a separate structure for securing the inflation and deflation interface (such as the aforementioned position-limiting cover) generally occupies a significant amount of space within the watch header mechanism 200, resulting in a reduction in the available space within the watch header mechanism 200, thereby restricting the design of the watch header mechanism 200 and the layout of its internal components.

[0061] 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 scheme 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 of the header mechanism 200 and the layout of internal devices due to insufficient space.

[0062] All directional indications in the embodiments of the present application (such as up, down, left, right, front, back...) are only used to explain the relative position 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 will also change accordingly. In addition, the terms "including" and "having" and any variations thereof 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.

[0063] Please refer to Figures 3 to 5 in conjunction with Figure 2. Figure 3 is a schematic diagram of the connection structure of part of the strap 111 and the connecting component 120 in Figure 2, Figure 4 is a schematic diagram of the partial structure of the airbag 112 in Figure 2, and Figure 5 is a schematic diagram of the partial cross-sectional structure of the wearable device 10 along V-V in Figure 1.

[0064] 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. As shown in Figures 2 and 3, 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 watch head mechanism 200 via the connecting assembly 120. The strap 111 can be used to cooperate with the watch head mechanism 200 to form a wearing space for the user. The airbag 112 is provided on the strap 111 and connected to the connecting assembly 120. The airbag 112 is also connected to the connecting assembly 120, allowing the watch head mechanism 200 to inflate and deflate the airbag 112 through the connecting assembly 120 to control its expansion or contraction, thereby cooperating with the watch head 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 watch head mechanism 200 to perform other measurement functions (such as heart rate measurement), which is not limited in this embodiment.

[0065] For example, the end of the strap 111 is connected to the connecting assembly 120, and the connecting assembly 120 is preferably embedded in the end of the strap 111. This not only enhances the connection between the strap 111 and the connecting assembly 120, but also shields the connecting assembly 120 with the strap 111, thereby enhancing the refined appearance of the strap mechanism 100. Furthermore, a portion of the connecting assembly 120 can protrude from the strap 111 to achieve a detachable connection with the watch head mechanism 200. Furthermore, the side of the strap 111 located within the wearing space can also be used to connect to the airbag 112, allowing the airbag 112 to fit the user's wrist, thereby cooperating with the watch head mechanism 200 to measure the user's blood pressure. For example, a connection hole 1111 is provided on one side of the watch strap 111 located in the wearing space, and a connection post 1121 (shown in FIG4 ) is provided on the air bag 112 that is inserted into the connection hole 1111 and has an interference fit with the watch strap 111, so as to achieve a detachable connection between the watch strap 111 and the air bag 112 (the positions of the connection hole 1111 and the connection post 1121 can also be interchanged). Alternatively, a Velcro can be provided on one side of the watch strap 111 located in the wearing space, and the Velcro can be used to detachably connect to the air bag 112. In this embodiment, the material of the watch strap 111 can be TPU (Thermoplastic Urethane), a knitted material, or fluororubber. Of course, the material of the watch strap 111 is not limited to this, and this embodiment does not list them one by one here.

[0066] Alternatively, in addition to being embedded within the end of the watch strap 111, the connecting assembly 120 may be connected to the end of the watch strap 111 in other ways. This only requires ensuring sufficient connection strength between the watch strap 111 and the connecting assembly 120 and that the connecting assembly 120 can cooperate with the watch head mechanism 200. This is not a limitation in this embodiment. Furthermore, in addition to being detachably connected to the airbag 112, the watch strap 111 may also be fixedly connected to the airbag 112, such that the watch strap 111 and the airbag 112 are inseparable. This only requires ensuring that the airbag 112 can communicate with the connecting assembly 120. This is also not a limitation in this embodiment.

[0067] The airbag 112 is located on the side of the watchband 111 that is located within the wearable space. The airbag 112 is also connected to the connecting assembly 120 and communicates with the connecting assembly 120. As shown in Figures 4 and 5, the airbag 112 may include an airbag body 1122 and an air nozzle 1123. The airbag body 1122 is located on the side of the watchband 111 that is located within the wearable space and is connected to the watchband 111. The aforementioned connecting post 1121 may be provided on the side of the airbag body 1122 that faces the watchband 111. The air nozzle 1123 is located at the end of the airbag body 1122, on the side of the airbag body 1122 that faces the watchband 111, and communicates with the interior of the airbag body 1122. At the same time, the air nozzle 1123 can also be connected to the connecting assembly 120, and connect the airbag body 1122 and the connecting assembly 120, so that the meter head mechanism 200 can inflate and deflate the airbag body 1122 through the connecting assembly 120, thereby achieving expansion or contraction of the airbag body 1122. In this embodiment, the air nozzle 1123 is preferably inserted into the connecting assembly 120 to communicate with the connecting assembly 120.

[0068] Optionally, to improve the airtightness of the airbag body 1122, the airbag body 1122 and the air nozzle 1123 may be fixed by heat pressing to improve the tightness of the connection between the airbag body 1122 and the air nozzle 1123. Of course, the airbag body 1122 and the air nozzle 1123 may also be connected by other methods, which are not limited in this embodiment.

[0069] Optionally, 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 disposed around the circumference of the air nozzle 1123. When the air nozzle 1123 is inserted into the connecting assembly 120, the sealing ring 1124 can abut against the air nozzle 1123 and the connecting assembly 120, respectively, filling 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 can be made of an elastic material such as silicone, rubber, or soft plastic, so that the sealing ring 1124 can abut against the air nozzle 1123 and the connecting assembly 120. Optionally, in addition to the sealing ring 1124, glue can also be applied to seal the connection between the air nozzle 1123 and the connecting assembly 120.

[0070] Optionally, there may be two air nozzles 1123, and the two air nozzles 1123 may be symmetrically arranged at the ends of the airbag body 1122 and inserted into the connecting assembly 120 to connect the airbag body 1122 and the meter mechanism 200, so that the meter mechanism 200 can inflate and deflate the airbag body 1122 through the two air nozzles 1123. Of course, in addition to being symmetrically arranged, the two air nozzles 1123 may also be arranged according to design requirements, as long as the two air nozzles 1123 can be inserted into the connecting assembly 120 to achieve communication between the airbag body 1122 and the connecting assembly 120. This is not limited in this embodiment.

[0071] Optionally, when there are two air nozzles 1123, the airbag body 1122 can have two independent cavities, and the two cavities can be respectively connected to the two air nozzles 1123. When the user wears the wearable device 10, one cavity can cover most of the user's wrist, allowing the airbag body 1122 to expand widely after inflation, tightening the user's wrist and compressing the blood vessels. The other cavity can cover the area where the radial artery is located in the user's wrist, allowing the airbag body 1122 to expand slightly after inflation to fit the arterial area of ​​the user's wrist, thereby cooperating with the meter mechanism 200 to measure the user's pulse pressure wave and other data, ultimately realizing the blood pressure measurement function of the wearable device 10.

[0072] 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 the airbag body 1122 can be provided with a hard structure for the connection component 120 to be inserted, so as to achieve communication between the airbag body 1122 and the connection component 120. Alternatively, the airbag body 1122 itself can be directly inserted into the connection component 120 to achieve communication between the airbag body 1122 and the connection component 120. Alternatively, the airbag body 1122 and the connection component 120 are an integrated structure that is connected to each other to achieve communication between the airbag body 1122 and the connection component 120, which is not limited in this embodiment.

[0073] Optionally, the airbag 112 is not limited to being located on the side of the watchband 111 facing the wearer's space. For example, the airbag 112 may comprise only the airbag body 1122, which may be embedded within the watchband 111 and connected to the connecting assembly 120 within the watchband 111. Furthermore, considering the expansion of the airbag body 1122, the watchband 111 is preferably made of a material that deforms as the airbag body 1122 expands, thereby minimizing the restriction imposed by the watchband 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 of the above-described embodiment and will not be further described here.

[0074] Please refer to Figures 6 to 8 in conjunction with Figure 5. Figure 6 is a structural diagram of the connecting component 120 in Figure 2, Figure 7 is a structural diagram of the connecting head 121 in Figure 6, and Figure 8 is a structural diagram of the connecting head 121 in Figure 6 from another perspective.

[0075] The connecting assembly 120 is connected to the end of the watch strap 111 and is detachably mounted on the watch head mechanism. The connecting assembly 120 also connects the airbag body 1122 and the watch head mechanism 200, allowing the watch head mechanism 200 to inflate and deflate the airbag body 1122 through the connecting assembly 120. As shown in FIG5 , the connecting assembly 120 has an air passage 1201. When the connecting assembly 120 is detachably connected to the watch head mechanism 200, the air passage 1201 can simultaneously connect the airbag body 1122 and the watch head mechanism 200, allowing the watch head mechanism 200 to inflate and deflate the airbag body 1122 through the air passage 1201 to achieve expansion or contraction of the airbag body 1122. With this arrangement, the connecting assembly 120 can secure the connection between the air passage 1201 and the meter header mechanism 200 through a detachable connection with the meter header mechanism 200. This allows the meter header mechanism 200 to omit the structure required to secure the air passage 1201, thereby increasing the available space of the meter header mechanism 200 and reducing the limitations on the design and internal component layout of the meter header mechanism 200 due to insufficient space. The structure of the connecting assembly 120 is described in detail below.

[0076] As shown in Figures 5 to 8, 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 header mechanism 200 to be detachably connected to the header mechanism 200. At the same time, the connector 121 can also have the aforementioned air channel 1201, and when the connector 121 is inserted into the header mechanism 200, part of the air channel 1201 can also be inserted into the header mechanism 200 synchronously with the connector 121, and the insertion direction of the connector 121 is parallel to the insertion direction of the air channel 1201. The sealing cover 122 is provided on the connector 121, and the sealing cover 122 is used to seal the opening on the connector 121 left due to the processing to form the air channel 1201, so as to ensure the sealing of the air channel 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 an in-mold injection molding process. The connector 121 and the sealing cover 122 are preferably made of hard plastic to provide a certain structural strength to the connection assembly 120 and help reduce the weight of the connection assembly 120. Of course, the connection method between the connector 121 and the strap 111, as well as the materials used for the connector 121 and the sealing cover 122, can also be adjusted according to design requirements, and this embodiment does not limit this.

[0077] Alternatively, 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 thereto. 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 in communication therewith. The following description will only take the example of the connector 121 being inserted into the meter header mechanism 200, and the airway 1201 being simultaneously inserted into the meter header mechanism 200 along with the connector 121.

[0078] It can be understood that the connector 121 can be inserted into the watch header mechanism 200 from the side of the watch header mechanism 200. For example, the side of the watch header mechanism 200 can be provided with an opening for inserting part or all of the connector 121.

[0079] Exemplarily, the connector 121 can be the head of the watchband 111, and the connector 121 includes: a main body 1211, a conductive portion 1212, a protruding portion 1213, and a buckle portion 1214. The main body 1211 can be embedded in the end of the watchband 111 to connect the connector 121 to the watchband 111. The conductive portion 1212 is connected to the main body 1211 and protrudes from the outside of the watchband 111. The end of the conductive portion 1212 away from the main body 1211 can also be inserted into the watchhead mechanism 200. The protruding portion 1213 is connected to the main body 1211 and is inserted into the watchband 111. When the watchband 111 and the watchhead mechanism 200 are combined to form a wearing space, the protruding portion 1213 can also be exposed on the side of the watchband 111 facing the wearing space to allow the air nozzle 1123 to be inserted. The buckle portion 1214 is connected to the side of the main body 1211 where the conductive portion 1212 is provided, and is provided to protrude from the end of the watch strap 111. 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 conductive portion 1212 can be inserted into the watch header mechanism 200 simultaneously with the buckle portion 1214, and the insertion direction of the conductive portion 1212 is also parallel to the insertion direction of the buckle portion 1214. The main body 1211, the conductive portion 1212, the protrusion 1213, and the sealing cover 122 can collectively constitute the aforementioned air channel 1201, so that the air channel 1201 can connect the airbag body 1122 and the watch header mechanism 200.

[0080] 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. When the buckle portion 1214 is detachably connected to the watch head mechanism 200, the first side 1211a can also be positioned opposite the watch head mechanism 200. The second side 1211b and the third side 1211c are both connected to the first side 1211a and are positioned opposite each other. The second side 1211b is also positioned near the side of the watch strap 111 facing the wearer's space and is used to connect to the protrusion 1213, so that the protrusion 1213 is exposed on the side of the watch strap 111 facing the wearer's space. The third side 1211c can be used for processing the main body 1211 by a processing part, and the third side 1211c can have an opening left over from processing to form the air channel 1201. The sealing cover 122 is provided on the third side 1211c to seal the opening left over from processing to form the air channel 1201.

[0081] The terms "first," "second," and "third" in this application are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first," "second," or "third" may explicitly or implicitly include at least one of such features.

[0082] 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 protrusion 1213, and the sealing cover 122. As shown in Figures 5 and 7-8, the air-guiding space 1201a can be connected to the conducting portion 1212 on the first side 1211a, thereby connecting to the meter header mechanism 200 through the conducting portion 1212. At the same time, the air-guiding 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. The first opening 1202a can be connected to the protrusion 1213 on the second side 1211b, so that the air-guiding space 1201a can also be connected to the airbag body 1122 through the protrusion 1213 and the air nozzle 1123. Second opening 1202b is a workpiece, and thus the opening remaining after machining main body 1211 on third side 1211c to form air-guiding space 1201a. Sealing cover 122 can be disposed on third side 1211c to seal second opening 1202b. Through this arrangement, the inner wall of air-guiding space 1201a, along with conducting portion 1212, protruding portion 1213, and one side of sealing cover 122 located within air-guiding space 1201a (hereinafter referred to simply as sealing cover 122), can collectively constitute the aforementioned airway 1201.

[0083] Alternatively, the first opening 1202a is not limited to being located on the second side 1211b. For example, when the airbag body 1122 is disposed within the watchband 111, the first opening 1202a may also be located on the third side 1211c, and the connection 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, the first opening 1202a may also be located on any outer surface of the main body 1211 besides the third side 1211c. This is sufficient as long as the airbag body 1122 can communicate with the air guide space 1201a through the first opening 1202a. This is not a limitation in this embodiment.

[0084] It is understood that if the conductive portion 1212 and the protruding portion 1213 extend in the direction of their extension and form a hole in the main body 1211 for communication, the hole formed by the two can only communicate at the intersection of their extension directions. The area of ​​the main body 1211 corresponding to the intersection of the conductive portion 1212 and the protruding portion 1213 in the extension direction needs to be sufficiently thick. Otherwise, the hole formed by the conductive portion 1212 and the protruding portion 1213 in the direction of their extension will directly pass through the main body 1211, and communication within the main body 1211 will be impossible. Increasing the thickness of the main body 1211 not only increases the weight of the connector 121, but also affects the thickness of the watchband 111 (the main body 1211 is embedded in the watchband 111), which is not conducive to the overall lightweight design of the watchband mechanism 100.

[0085] Based on this, this embodiment, by opening an air-guiding space 1201a on the third side 1211c to connect the conductive portion 1212 and the protruding portion 1213, can shorten the length of the holes opened in the conductive portion 1212 and the protruding portion 1213 in their extending direction, thereby reducing the required thickness of the main body 1211 at the connection point between the conductive portion 1212 and the protruding portion 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 air channel 1201 from the second opening 1202b. For example, the wall surface at the connection point between the air-guiding space 1201a and the conductive portion 1212 (at the corner of the air channel 1201) can be polished from the second opening 1202b to grind the sharp edge surface into a curved surface, thereby improving the air-guiding effect of the air channel 1201.

[0086] Optionally, to prevent the sealing cover 122 from forming a protrusion 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 disposed within the receiving groove 1203 and block the second opening 1202b. The receiving groove 1203 may also absorb the thickness of the sealing cover 122, thereby preventing the sealing cover 122 from forming a protrusion on the third side 1211c. Furthermore, the sealing cover 122 may be secured within the receiving groove 1203 by dispensing glue or spot welding to enhance the secure connection and sealing performance between 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 that of the receiving groove 1203 to facilitate installation of the sealing cover 122.

[0087] Optionally, the sealing cover 122 may be spaced apart from the sidewalls of the receiving groove 1203, so that a gap exists between the sealing cover 122 and the sidewalls of the receiving groove 1203. With this arrangement, when the watch strap 111 and the connector 121 undergo an in-mold injection molding process, the watch strap 111 may also fill the gap between the sealing cover 122 and the sidewalls of the receiving groove 1203, thereby further improving the secure connection between the watch strap 111, the connector 121, and the sealing cover 122.

[0088] Optionally, the design of the sealing cover 122 can also be omitted. In this case, 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 into two independent structural parts, and the two independent structural parts can form the entire main body 1211 after splicing, and can be jointly enclosed to form the air guide space 1201a after splicing, thereby omitting the design of forming the second opening 1202b on the third side 1211c of the air guide space 1201a. 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 substances. 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 portion 1212 and the protruding portion 1213.

[0089] Optionally, the first side 1211a may be recessed toward the inside of the main body 1211 to form a clearance space 1204 for circumventing the meter header mechanism 200, and both the conductive portion 1212 and the latch portion 1214 may be located within the clearance space 1204. When the latch portion 1214 and the conductive portion 1212 are simultaneously inserted into the meter header mechanism 200, the clearance space 1204 may be used to circumvent the meter header mechanism 200 to avoid interference with the meter header mechanism 200, thereby ensuring that the latch portion 1214 and the conductive portion 1212 can be inserted into place.

[0090] Optionally, the main body 1211 can be curved toward the side of the watchband 111 closest to the wearing space, allowing the main body 1211 to curve toward the wearing space. This allows the end of the watchband 111 where the main body 1211 is embedded to bend, thereby forming a wearing space together with the watch head mechanism 200. Furthermore, the sealing cover 122 can also mate with the third side 1211c of the main body 1211. Specifically, the surface of the sealing cover 122 exposed on the third side 1211c can also be curved, thereby preventing the sealing cover 122 from forming a protrusion on the third side 1211c. Furthermore, the thickness of the main body 1211 gradually decreases away from the conductive portion 1212, allowing the thickness of the watchband 111 to also gradually decrease away from the conductive portion 1212, facilitating a thinner and lighter design for the watchband 111. Of course, the shape of the main body 1211 is not limited to any particular shape and can be adjusted to suit design requirements, which is not a limitation in this embodiment.

[0091] 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 to the main body 1211, which is conducive to improving the fit between the airbag body 1122 and the user's wrist after inflation.

[0092] Furthermore, the conducting portion 1212 is connected to the first side 1211a and can be inserted into the watch header mechanism 200 simultaneously with the snap portion 1214 being inserted into the watch header mechanism 200. The conducting portion 1212 also defines an air guide hole 1201b that connects the air guide space 1201a and the watch header mechanism 200. 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 protrusion 1213 and the sealing cover 122. The axial direction of the air guide hole 1201b can be parallel to the insertion direction of the conducting portion 1212. The air guide hole 1201b can penetrate opposite sides of the conducting portion 1212, close to and away from the main body 1211, and simultaneously penetrate the first side 1211a of the main body 1211, to communicate 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 watch header mechanism 200 after the end of the conducting portion 1212 away from the main body 1211 is inserted into the watch header mechanism 200 .

[0093] Optionally, in order to reduce the probability of air leakage at the connection between the conductive portion 1212 and the meter header mechanism 200, the connecting assembly 120 may further be provided with a sealing ring 123 (shown in Figures 5 and 6) sleeved on the conductive portion 1212, and when the conductive portion 1212 is inserted into the meter header mechanism 200, the sealing ring 123 may respectively abut against the conductive portion 1212 and the meter header mechanism 200 to fill the gap between the conductive portion 1212 and the meter header mechanism 200, thereby reducing the probability of air leakage at the connection between the conductive portion 1212 and the meter header mechanism 200. In this embodiment, the sealing ring 123 may also be made of an elastic material such as silicone, rubber, and soft plastic, so that the sealing ring 123 can abut against the conductive portion 1212 and the meter header mechanism 200 respectively.

[0094] Optionally, the air guide hole 1201b may not be limited to passing through the side of the conductive part 1212 away from the main body 1211, and the air guide hole 1201b may also pass through the peripheral side of the conductive part 1212, and the strap mechanism 100 may also be connected to the air guide hole 1201b from the peripheral side of the conductive part 1212.

[0095] Alternatively, the design of the conducting portion 1212 can be omitted. In this case, to achieve communication between the air-guiding space 1201a and the meter header mechanism 200, the air-guiding space 1201a can also form a third opening on the first side 1211a. The meter header mechanism 200 can be provided with a structure similar to the conducting portion 1212, and the third opening can avoid the meter header mechanism 200, allowing the meter header mechanism 200 to be inserted into the air-guiding space 1201a through the third opening to achieve communication between the meter header mechanism 200 and the air-guiding space 1201a. In this embodiment, when the design of the conducting portion 1212 is omitted, the inner wall of the air-guiding space 1201a can be used to form the aforementioned air channel 1201 together with the protrusion 1213 and the sealing cover 122.

[0096] Furthermore, the protrusion 1213 is connected to the second side 1211b and is disposed through the watchband 111. The protrusion 1213 is also exposed on the side of the watchband 111 facing the wearing space. The protrusion 1213 can also be disposed around the first opening 1202a, forming a receiving hole 1201c that connects the air guide space 1201a and the air nozzle 1123. 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. Because the protrusion 1213 is provided through the watchband 111, the receiving hole 1201c can be exposed on the side of the watchband 111 facing the wearing space, allowing the air nozzle 1123 to be inserted. The sealing ring 1124 can respectively abut the air nozzle 1123 and the inner wall of the receiving hole 1201c to improve the sealing performance 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.

[0097] 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.

[0098] Optionally, when the airbag 112 is provided with a hard structure on the airbag body 1122 into which the protrusion 1213 is inserted, the protrusion 1213 can be inserted into the hard structure to connect the air-guiding space 1201a and the airbag body 1122 via the receiving hole 1201c. Alternatively, the protrusion 1213 can be directly inserted into the airbag body 1122 and fixedly connected thereto, so that the airbag body 1122 and the connector 121 form a connected, integrated structure.

[0099] Alternatively, the protrusion 1213 can be omitted. In this case, to connect the air-guiding space 1201a with the meter head mechanism 200, the air nozzle 1123 can be directly inserted into the air-guiding space 1201a through the first opening 1202a, thereby connecting the airbag body 1122 and the air-guiding space 1201a. In this embodiment, when the protrusion 1213 is omitted, the inner wall of the air-guiding space 1201a can be used to form the aforementioned air channel 1201 together with the inner wall of the air-guiding hole 1201b and the sealing cover 122.

[0100] Alternatively, the design of the conducting portion 1212 and the protruding portion 1213 can be omitted. In this case, the inner wall of the air-guiding space 1201a and the sealing cover 122 can jointly form the aforementioned air channel 1201. Alternatively, the design of the conducting portion 1212, the protruding portion 1213, and the sealing cover 122 can be omitted. In this case, the inner wall of the air-guiding space 1201a can form the aforementioned air channel 1201.

[0101] Optionally, when the number of the air nozzles 1123 is two, the number of the air passages 1201 may also be two, so as to be respectively connected to the two air nozzles 1123. As shown in Figures 5 to 8, 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 respectively 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 seal the two second openings 1202b formed on the third side 1211c of the two air guide spaces 1201a. In this embodiment, the two air-guiding spaces 1201a, the two conducting portions 1212, the two protruding portions 1213, and the two sealing covers 122 may be symmetrically arranged about the length direction L. The coordination relationship between a 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 previous embodiment and will not be described in detail here.

[0102] Furthermore, the latch portion 1214 is connected to the first side 1211a and is used to be inserted into the watch header mechanism 200 for detachable connection with the watch header mechanism 200. As shown in Figures 7 and 8, the latch portion 1214 can be provided with a slot 12141. When the latch portion 1214 is inserted into the watch header mechanism 200, a mating structure of the watch header mechanism 200 can enter the slot 12141 and engage with the latch portion 1214 in a direction in which the latch portion exits the watch header mechanism 200, thereby achieving a fixed connection between the latch portion 1214 and the watch header mechanism 200. At the same time, the mating structure of the watch header mechanism 200 can also exit the slot 12141 to release the engagement with the latch portion 1214, allowing the latch portion 1214 to be removed from the watch header mechanism 200, thereby achieving a detachable connection between the latch portion 1214 and the watch header mechanism 200. In this embodiment, when there are two conducting portions 1212 , the locking portion 1214 is further located between the two conducting portions 1212 that are spaced apart.

[0103] Optionally, in addition to being used for detachable connection with the watch header mechanism 200, the buckle portion 1214 may also be provided with the aforementioned air guide hole 1201b, so as to simultaneously communicate with the watch header mechanism 200 when inserted into the watch header mechanism 200. In other words, the buckle portion 1214 can simultaneously function as a detachable connection with the watch header mechanism 200 and as a communication channel 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 manner in which the air guide hole 1201b is provided on the buckle portion 1214 can be the same or similar to that of the aforementioned embodiment and will not be further described here.

[0104] Optionally, there may be two latching portions 1214, spaced apart between the two conductive portions 1212, each configured to be inserted into the meter header mechanism 200 for removable connection thereto, thereby enhancing the secure connection between the connecting assembly 120 and the meter header mechanism 200. The two latching portions 1214 may also be symmetrically arranged to enhance consistency in insertion into the meter header mechanism 200. Furthermore, the latching slots 12141 on each latching portion 1214 may extend through the sides of the two latching portions 1214 proximate to each other, forming corresponding clearances between the two latching portions 1214, thereby facilitating entry of the mating structure of the meter header mechanism 200 into the latching slots 12141. Of course, the specific design of the latching slots 12141 can be adjusted as needed, as long as the mating structure of the meter header mechanism 200 can enter the latching slots 12141 and engage with the latching portions 1214. This is not a limitation in this embodiment.

[0105] Please refer to Figures 9 to 13. Figure 9 is a schematic diagram of another partial cross-sectional structure of the wearable device 10 along V-V in Figure 1, Figure 10 is a schematic diagram of the structure of the connecting component 120 in Figure 9, Figure 11 is a schematic diagram of the structure of the connecting head 121 in Figure 10, Figure 12 is a schematic diagram of the structure of the air guide 124 in Figure 10, and Figure 13 is a partial enlarged view of point A in Figure 10.

[0106] In addition to using the connector 121 and the sealing cover 122 to form the air channel 1201, the air channel 1201 can also be formed by other independent structural parts. As shown in Figures 9 and 10, the connection assembly 120 provided in this embodiment may include: a connector 121 and an air guide 124. Among them, the connector 121 can be connected to the end of the watch strap 111, and the connector 121 can also be assembled on the header mechanism 200 and detachably connected to the header mechanism 200. The air guide 124 can be provided on the connector 121, and the air channel 1201 is formed on the air guide 124 to connect the airbag body 1122 and the header mechanism 200 respectively when the connector 121 is connected to the header mechanism 200, thereby realizing the inflation and deflation of the airbag body 1122 by the header mechanism 200. With this arrangement, the connecting assembly 120 can secure the connection between the air passage 1201 and the meter header mechanism 200 through a detachable connection with the meter header mechanism 200. This allows the meter header mechanism 200 to omit the structure required to secure the air passage 1201, thereby increasing the available space of the meter header mechanism 200 and reducing the limitations on the design and internal component layout of the meter header mechanism 200 due to insufficient space. The structures of the connecting head 121 and the air guide 124 provided in this embodiment are further described below.

[0107] As shown in Figures 9 to 11, the connector 121 is inserted into the watch head mechanism 200 and is detachably connected thereto. The connector 121 may include a main body 1211 and a snap-fit ​​portion 1214. The shape of the main body 1211 is the same or similar to that of the previous embodiment, except that the main body 1211 provided in this embodiment does not have an air guide space 1201a. The main body 1211 is used solely for mounting the air guide 124 and connecting to the watch strap 111. For example, the main body 1211 defines a mounting groove 1205 extending through the first side 1211a and the second side 1211b. The mounting groove 1205 is used to mount the air guide 124. The air channel 1201 formed by the air guide 124 can communicate with the watch head mechanism 200 from the first side 1211a and with 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 head mechanism 200 are the same as or similar to those in the above embodiment and are not described in detail here.

[0108] The air guide 124 is disposed within the mounting groove 1205, and when the connector 121 (the snap-fit ​​portion 1214) is inserted into the meter header mechanism 200, the air guide 124 can be simultaneously inserted into the meter header mechanism 200, thereby connecting the air passage 1201 with the meter header mechanism 200. As shown in Figures 9 to 12, the air guide 124 includes an air guide tube 1241 and a fixing plate 1242. The air guide tube 1241 is disposed within the mounting groove 1205 and has an air passage 1201. The air guide tube 1241 also protrudes from the first side 1211a and the second side 1211b, respectively, to connect to the meter header mechanism 200 and the airbag body 1122, thereby connecting the air passage 1201 with the meter header mechanism 200 and the airbag body 1122. The fixing plate 1242 is mounted over the portion of the air duct 1241 protruding from the first side 1211a and is connected to the first side 1211a. It is used to secure the air duct 1241 within the mounting groove 1205. In this embodiment, the air duct 1241 may be made of plastic, and the fixing plate 1242 may be made of metal. The air duct 1241 and fixing plate 1242 may be integrally formed using a metal insert injection molding process to enhance the secure connection between the two. Of course, the air duct 1241 and fixing plate 1242 may also be fixedly connected using other methods; the fixing plate 1242 only needs to be able to secure the air duct 1241.

[0109] Exemplarily, the air duct 1241 may include a first air duct 1241a and a second air duct 1241b. One end of the first air duct 1241a is located within the mounting groove 1205, while the other opposite end protrudes from the first side 1211a and is configured to be inserted into the meter header mechanism 200 simultaneously with the buckle portion 1214 being inserted into the meter header mechanism 200. The first air duct 1241a further defines a first air hole 1206a communicating with the meter header mechanism 200. The first air hole 1206a may also extend through a side of the first air duct 1241a away from the second air duct 1241b. One end of the second air duct 1241b is connected to the end of the first air duct 1241a located within the mounting groove 1205, while the other opposite end protrudes from the second side 1211b and the side of the watchband 111 facing the wearing space, allowing insertion into the airbag body 1122. The second air duct 1241b also defines a second air hole 1206b that connects the first air hole 1206a with the airbag body 1122. This second air hole 1206b extends through the side of the second air duct 1241b away from the first air duct 1241a. In this embodiment, the inner walls of the first air hole 1206a and the second air hole 1206b form an air channel 1201, connecting the watch head mechanism 200 and the airbag body 1122, allowing the watch head mechanism 200 to inflate and deflate the airbag body 1122.

[0110] Optionally, in addition to being used to insert the meter header mechanism 200, the first air duct 1241a can also be inserted into the meter header mechanism 200. That is, the meter header mechanism 200 can also be inserted into the first air hole 1206a to achieve communication with the airway 1201. Furthermore, when the first air duct 1241a is inserted into the meter header mechanism 200, the first air duct 1241a can be positioned solely within the mounting groove 1205, rather than protruding from the first side 1211a.

[0111] Optionally, in addition to being used to insert the airbag body 1122, the second air guide tube 1241b can also be used to insert the airbag body 1122. Specifically, the airbag body 1122 can be inserted into the second air hole 1206b via the aforementioned air nozzle 1123 to achieve communication with the airway 1201. Furthermore, when the air nozzle 1123 is inserted into the second air guide tube 1241b, the second air guide tube 1241b can be positioned solely within the mounting groove 1205, rather than protruding from the second side 1211b.

[0112] Alternatively, when the second air guide tube 1241b is inserted into the airbag body 1122, the air nozzle 1123 can be omitted. The second air guide tube 1241b can function similarly to the air nozzle 1123 and be secured to the airbag body 1122 by heat pressing or other methods. During assembly, the airbag body 1122 can be first connected to the second air guide tube 1241b, and then the air guide member 124 with the airbag body 1122 can be installed into the mounting groove 1205.

[0113] Optionally, the axial directions of the first air hole 1206a and the second air hole 1206b can intersect to form an angle α greater than 90° (as shown in FIG12 ). Furthermore, to facilitate connection between the second air duct 1241b and the airbag body 1122, the end of the second air duct 1241b away from the first air duct 1241a can be inserted through the thickness direction of the watchband 111. This allows the airbag body 1122 to be connected to the second air hole 1206b via the air nozzle 1123 and fit more closely on the watchband 111, thereby facilitating the expansion of the airbag body 1122 and compressing the user's wrist. Optionally, when the airbag body 1122 is embedded in the watchband 111, the second air duct 1241b can be directly inserted into the airbag body 1122 without being inserted through the watchband 111.

[0114] Optionally, an avoidance groove 1211d connected to the installation groove 1205 is also provided on the third side 1211c, and the avoidance groove 1211d is used to avoid the installation of the air duct 1241 to avoid interference between the air duct 1241 and the inner wall of the installation groove 1205, resulting in the problem of improper installation of the air duct 1241.

[0115] Furthermore, a fixing plate 1242 is provided on the first side 1211a and is sleeved over the portion of the first air duct 1241a that protrudes from the first side 1211a. The fixing plate 1242 is used to fix the positions of the first air duct 1241a and the second air duct 1241b. As shown in Figures 9, 11, and 13, a fixing groove 1207 is provided on the first side 1211a, and the mounting groove 1205 extends through the bottom wall of the fixing groove 1207. The fixing groove 1207 can be used to install the fixing plate 1242 to improve the connection between the fixing plate 1242 and the main body 1211. In this embodiment, the fixing plate 1242 can be fixed in the fixing groove 1207 by means such as welding or threaded connection. Optionally, the design of the fixing groove 1207 can also be omitted.

[0116] Optionally, in order to further improve the connection firmness between the fixing plate 1242 and the main body 1211, a positioning groove 1208 is also provided on the side wall of the fixing groove 1207, and the fixing plate 1242 is also provided with a positioning portion 12421 protruding from the positioning groove 1208, so that the positioning portion 12421 and the positioning groove 1208 can cooperate to position the fixing plate 1242, thereby improving the connection firmness between the fixing plate 1242 and the main body 1211.

[0117] Optionally, to further enhance the secure connection between the fixing plate 1242 and the main body 1211, a limiting groove 1209 communicating with the fixing groove 1207 may be provided on the first side 1211a, with the limiting groove 1209 being disposed opposite the positioning groove 1208. Furthermore, the fixing plate 1242 may be provided with a limiting portion 12422 protruding from the limiting groove 1209. The limiting portion 12422 cooperates with the limiting groove 1209 to limit the fixing plate 1242, thereby enhancing the secure connection between the fixing plate 1242 and the main body 1211.

[0118] Optionally, when the air duct 1241 and the fixing plate 1242 are integrally formed by metal insert injection molding, the side of the first air duct 1241a facing away from the first air hole 1206a further includes an annular ridge 1241c, so as to increase the thickness of the first air duct 1241a. Furthermore, the fixing plate 1242 can be sleeved onto the side of the annular ridge 1241c facing away from the first air duct 1241a and include a coupling portion 12423 (shown in FIG. 9 ) embedded within the annular ridge 1241c and the first air duct 1241a. The coupling portion 12423 can also be bent and embedded within the annular ridge 1241c and the first air duct 1241a, thereby enhancing the secure connection between the air duct 1241 and the fixing plate 1242. In this embodiment, the number of the coupling portions 12423 can also be multiple, so that the fixing plate 1242 can be firmly mounted on the first air guide tube 1241a. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0119] Optionally, the fixing plate 1242 may be omitted, and the air duct 1241 may be disposed in the mounting groove 1205 in other detachable or non-detachable manners. For example, the air duct 1241 may be connected to the main body 1211 by welding, bonding, or clamping to be fixed in the mounting groove 1205.

[0120] Optionally, the connection assembly 120 provided in this embodiment may also have two air passages 1201. As shown in Figures 10 and 11, the main body 1211 may have two mounting slots 1205, and the number of air guides 124 may be two, and the two air guides 124 may be installed in the two mounting slots 1205, respectively, so that the connection assembly 120 has two air passages 1201. The mating relationship between a single air guide 124 and the main body 1211 can be referred to in the previous embodiment and will not be repeated here.

[0121] Optionally, when there are two air guides 124, the snap-fit ​​portion 1214 may be located between two spaced-apart first air guide tubes 1241a. Furthermore, to match the watch head mechanism 200, the area of ​​the first side 1211a between the two first air guide tubes 1241a may be recessed toward the inside of the main body 1211 to form an escape space 1204. The snap-fit ​​portion 1214 may be located within the escape space 1204.

[0122] The connection assembly 120 provided in this embodiment has an air guide 124 having an air channel 1201 disposed on the connector 121. The air channel 1201 is also capable of connecting the airbag body 1122 and the watch head mechanism 200 when the connector 121 is connected to the watch strap 111 and the watch head mechanism 200, respectively. This allows the connector 121 to secure the connection between the air channel 1201 and the watch head mechanism 200 when the connector 121 is detachably connected to the watch head mechanism 200. With this arrangement, the watch head mechanism 200 can omit the structure required to secure the air channel 1201, thereby increasing the available space of the watch head mechanism 200 and reducing the limitations on the design and internal component layout of the watch head mechanism 200 due to insufficient space.

[0123] Please refer to Figures 14 to 16 in conjunction with Figures 5 and 9. Figure 14 is a structural schematic diagram of the header mechanism 200 in Figure 1, Figure 15 is a connection structure schematic diagram of the frame 211, the air pump assembly 230 and the detection assembly 220 in Figure 14, and Figure 16 is a partial cross-sectional structure schematic diagram of the frame 211 and the detection assembly 220 along VI-VI in Figure 15.

[0124] The meter mechanism 200 is detachably connected to the buckle portion 1214 and can be synchronously connected to the airway 1201 when detachably connected to the buckle portion 1214. The meter mechanism 200 can inflate and deflate the airbag body 1122 through the airway 1201 to expand or contract the airbag body 1122. As shown in Figures 14 to 16, the meter mechanism 200 includes: a housing assembly 210, a detection assembly 220, an air pump assembly 230, and an unlocking assembly 240. The housing assembly 210 can be used to install the air pump assembly 230 and can be inserted into the buckle portion 1214. The housing assembly 210 also has an air path 201 connecting the air pump assembly 230 and the airway 1201, allowing the air pump assembly 230 to inflate and deflate the airbag body 1122 through the air path 201 and the airway 1201. The detection assembly 220 is provided on the housing assembly 210 and is located within the air path 201. The detection assembly 220 is used to detect the airflow pressure within the air path 201. The unlocking assembly 240 is slidably provided on the housing assembly 210 and can be engaged with the latch portion 1214 inserted into the housing assembly 210. The unlocking assembly 240 can also be released from the latch portion 1214 by a user's pressure, thereby achieving a detachable connection between the latch portion 1214 and the housing assembly 210.

[0125] Specifically, the housing assembly 210 includes a frame 211. The frame 211 encloses a mounting space 2111 for accommodating the air pump assembly 230 and defines an air path 201 connecting the air pump assembly 230 and the side of the frame 211 facing away from the mounting space 2111. Furthermore, a slot 2112 is defined on the side of the frame 211 facing away from the mounting space 2111. This slot 2112 accommodates a latch 1214 and accommodates a portion of the unlocking assembly 240, allowing the latch 1214 to be removably connected to the side of the frame 211 facing away from the mounting space 2111 via the unlocking assembly 240. When the buckle portion 1214 is inserted into the slot 2112, the conducting portion 1212 or the first air duct 1241a (shown in Figures 5 and 9, and referred to as the air duct 1201 below) of the strap mechanism 100 can also be simultaneously inserted into the air path 201 from the side of the frame 211 away from the installation space 2111, thereby achieving communication between the air path 201 and the air duct 1201. In addition, the frame 211 is further provided with a slide groove 2113 connected to the slot 2112, and the unlocking assembly 240 can be slidably disposed in the slide groove 2113.

[0126] Optionally, in addition to installing the air pump assembly 230, the installation space 2111 can also be used to install other functional components required by the meter head mechanism 200, such as a battery, a speaker, and a microphone. Furthermore, when there are two latching portions 1214, there are also two slots 2112, each of which can accommodate the two latching portions 1214. Both slots 2112 can accommodate a portion of the unlocking assembly 240, allowing the two latching portions 1214 to still cooperate with the unlocking assembly 240 to achieve a detachable connection between the latching portions 1214 and the frame 211.

[0127] Optionally, the installation space 2111 may penetrate two opposite sides of the frame 211 to facilitate the installation of functional components into the installation space 2111. Simultaneously, the housing assembly 210 may further include a back cover 212, which may be disposed on the side of the frame 211 penetrated by the installation space 2111, shielding and enclosing the installation space 2111 to protect the functional components located within the installation space 2111. Furthermore, the meter header mechanism 200 may further include a display assembly 250, which may be disposed on the other opposite side of the frame 211 penetrated by the installation space 2111 to achieve the display function of the meter header mechanism 200 while cooperating with the back cover 212 to enclose the installation space 2111.

[0128] Please refer to Figures 17 to 19 in conjunction with Figure 16. Figure 17 is a structural schematic diagram of the frame 211 in Figure 15, Figure 18 is a partial cross-sectional structural schematic diagram of the frame 211, the air pump assembly 230 and the detection assembly 220 along Ⅶ-Ⅶ in Figure 15, and Figure 19 is a partial enlarged schematic diagram of point B in Figure 17.

[0129] As shown in Figures 16 to 19, the frame 211 includes a frame portion 2114 and a vent portion 2115. The frame portion 2114 encloses the aforementioned installation space 2111 and has a socket 2011 for inserting the air supply duct 1201 on a side facing away from the installation space 2111. The frame portion 2114 also has a slot 2112 for inserting the buckle portion 1214 on a side facing away from the installation space 2111. The slot 2112 is also located adjacent to the socket 2011. The opposite sides of the frame portion 2114, which are penetrated by the installation space 2111, are used to support the back cover 212 and the display assembly 250, respectively. The frame portion 2114 has the aforementioned slide groove 2113 on the side facing the back cover 212. The vent portion 2115 is connected to the frame portion 2114 and is located within the installation space 2111. The vent portion 2115 also defines a ventilation space 2012 that connects the jack 2011 and the air pump assembly 230. The detection assembly 220 is disposed on the vent portion 2115, with a portion of the detection assembly 220 also located within the ventilation space 2115, and is used to detect the airflow pressure within the ventilation space 2115. In this embodiment, the jack 2011 and the ventilation space 2012 together constitute the air path 201 disposed on the frame 211.

[0130] Alternatively, the design of the vent portion 2115 may be omitted, and the jack 2011 may be directly connected to the air pump assembly 230 located in the installation space 2111. For example, the air pump assembly 230 may be directly inserted into the jack 2011 from the side of the frame portion 2114 close to the installation space 2111 to communicate with the air duct 1201. Alternatively, the portion of the frame portion 2114 that forms the jack 2011 may be protruded toward the installation space 2111 and inserted into the air pump assembly 230 to communicate with the air pump assembly 230. In this embodiment, when the vent portion 2115 is omitted, the jack 2011 may independently constitute the air path 201 without having to constitute the air path 201 together with the ventilation space 201.

[0131] Furthermore, the vent portion 2115 has a first surface 21151 and a second surface 21152 disposed opposite to each other in the thickness direction of the watch header mechanism 200. The vent portion 2115 has a first vent groove 2012a defined on the first surface 21151 and a second vent groove 2012b defined on the second surface 21152. The first vent groove 2012a and the second vent groove 2012b are interconnected and together constitute the aforementioned vent space 2012. At the same time, the first vent groove 2012a is in communication with the insertion hole 2011, and the second vent groove 2012b is in communication with the air pump assembly 230. Both of these are used to buffer the airflow that the air pump assembly 230 injects into the ventilation space 2012, thereby slowing the rate at which the airflow enters the insertion hole 2011 through the first vent groove 2012a, thereby improving the precision of controlling the expansion and contraction of the airbag body 1122. In this embodiment, the insertion hole 2011 may have an opening formed on the sidewall of the first vent groove 2012a to communicate with the first vent groove 2012a, while the air pump assembly 230 may be in communication with the bottom wall of the second vent groove 2012b.

[0132] Furthermore, the first surface 21151 can be used to mount the detection assembly 220. The detection assembly 220 can also enclose the first ventilation groove 2012a on the first surface 21151 and protrude into the first ventilation groove 2012a. This allows for simultaneous detection of the airflow pressure within the ventilation space 2012 while enclosing the first ventilation groove 2012a. Accordingly, the housing assembly 210 can also include a sealing plate 213, which is disposed on the second surface 21152 and encloses the second ventilation groove 2012b. With this arrangement, the detection assembly 220 and the sealing plate 213 can be used to seal the ventilation space 2012, ensuring its airtightness.

[0133] Optionally, to prevent the sealing plate 213 from forming a protrusion on the second surface 21152, the second surface 21152 may further be provided with a receiving groove 21153, and the second vent groove 2012b may be provided on the bottom wall of the receiving groove 21153. The sealing plate 213 is disposed within the receiving groove 21153, and the shape and size of the sealing plate 213 may match or be slightly smaller than the receiving groove 21153, so as to facilitate installation of the sealing plate 213 within the receiving groove 21153. In this embodiment, the sealing plate 213 may be specifically adhesively fixed to the bottom wall of the receiving groove 21153 by dispensing glue. Of course, the sealing plate 213 may also be fixed within the receiving groove 21153 by other means, such as welding, threaded connection, or clamping, which is not limited in this embodiment.

[0134] Optionally, the ventilation portion 2115 is further provided with a boss 21154 connected to the air pump assembly 230, and the boss 21154 has a through hole 2013 connecting the second ventilation groove 2012b and the installation space 2111, so that the air pump assembly 230 can be connected to the second ventilation groove 2012b via the through hole 2013. In particular, the boss 21154 can be provided on the first surface 21151, and the through hole 2013 can penetrate the boss 21154 on opposite sides away from and close to the first surface 21151, and further penetrate the vent portion 2115 to form an opening on the bottom wall of the second ventilation groove 2012b, so that when the air pump assembly 230 inflates the second ventilation groove 2012b, the air flow can first be buffered by the sealing plate 213 covered on the second surface 21152, and then enter the first ventilation groove 2012a through the second ventilation groove 2012b to form a "U"-shaped flow path (shown by the dotted arrow in Figure 18). In this embodiment, the boss 21154 can be inserted into the air pump assembly 230 to achieve communication between the through hole 2013 and the air pump assembly 230, and the jack 2011, the ventilation space 2012 and the through hole 2013 can constitute the air path 201. Of course, in some embodiments, the design of the boss 21154 may be omitted, and the air pump assembly 230 may be directly inserted into the second ventilation groove 2012b to communicate with the second ventilation groove 2012b, which is not limited in this embodiment.

[0135] Optionally, to improve assembly convenience, a receiving groove 21155 (shown in Figures 18 and 19) is further provided on the first surface 21151 of the vent portion 2115, and the receiving groove 21155 also extends through a third surface 21156 of the vent portion 2115 connecting the first surface 21151 and the second surface 21152. A boss 21154 protrudes from the bottom wall of the receiving groove 21155 and can be assembled with the air pump assembly 230 in the thickness direction of the meter header mechanism 200. The opening formed on the third surface 21156 of the receiving groove 21155 can also avoid the air pump assembly 230, so that the air pump assembly 230 can be simultaneously connected to the boss 21154 when installed in the installation space 2111, thereby improving assembly convenience. Of course, in some embodiments, the design of the accommodating groove 21155 can also be omitted, and the boss 21154 can also be set at other positions of the vent portion 2115. It is only necessary that the through hole 2013 can connect the second vent groove 2012b and the air pump assembly 230. This embodiment does not limit this.

[0136] Optionally, when there are two air passages 1201, there can also be two air paths 201. Two insertion holes 2011 can be provided on the side of the frame portion 2114 facing away from the installation space 2111, and the two insertion holes 2011 can be respectively inserted into the two air passages 1201. Furthermore, the frame 211 can be provided with two vents 2115 within the installation space 2111, and the ventilation spaces 2012 of the two vents 2115 can be respectively connected to the two insertion holes 2011, thereby forming two air paths 201 to cooperate with the two air passages 1201. In this embodiment, the two vents 2115 are identical or similar in appearance and are spaced apart within the installation space 2111. The third surfaces 21156 of the two vents 2115 proximal to each other are penetrated by a receiving groove 21155, allowing the air pump assembly 230 to be assembled between the two vents 2115 and communicate with the ventilation spaces 2012 of the two vents 2115. Accordingly, the two receptacles 2011 may also be spaced apart on the side of the frame 2114 facing away from the installation space 2111, and the region of the frame 2114 between the two receptacles 2011 may be provided with a slot 2112. Furthermore, the communication method between the air pump assembly 230 and the single air path 201 and the airway 1201 can be referred to in the previous embodiment and will not be described in detail here.

[0137] Detection assembly 220 is located on the first surface 21151 of ventilating portion 2115 and covers the first vent groove 2012a. Detection assembly 220 is also protruded in the first vent groove 2012a to simultaneously serve as a closed ventilation space 2012 and to detect the airflow pressure in the ventilation space 2012. Detection assembly 220 comprises a support plate 221, a detection member 222, and an electrical connector 223. As shown in Figures 16 and 18, support plate 221 is covered on the first surface 21151 and covers the first vent groove 2012a to serve as a closed ventilation space 2012. Detection member 222 is located on a side of support plate 221 facing the first vent groove 2012a and protruded in the first vent groove 2012a to detect the airflow pressure in the ventilation space 2012. The electrical connector 223 is connected to the side of the support plate 221 facing away from the detection member 222, and is used to connect a power source to supply power to the detection member 222. In this embodiment, the support plate 221 can be a rigid circuit board, the detection member 222 can be a pressure sensor, and the electrical connector 223 can be a flexible circuit board.

[0138] Optionally, when there are two vents 2115, the detection assembly 220 may be provided with two corresponding support plates 221 and detection members 222, and the two support plates 221 and detection members 222 may be respectively disposed on the first surfaces 21151 of the two vents 2115 to respectively detect the airflow pressure within the ventilation spaces 2012 of the two vents 2115. The electrical connector 223 may be respectively connected to the two support plates 221 and simultaneously function on the two detection members 222, thereby reducing wiring within the installation space 2111.

[0139] Please refer to Figures 20 to 23 in conjunction with Figure 18, Figure 20 is a structural schematic diagram of the air pump assembly 230 in Figure 15, Figure 21 is a decomposed structural schematic diagram of the air pump 231 in Figure 20, Figure 22 is a cross-sectional structural schematic diagram of the air pump assembly 230 along IV-IV in Figure 20, and Figure 23 is a connection structural schematic diagram of the valve 232 and the hose 233 in Figure 20.

[0140] The air pump assembly 230 is disposed within the installation space 2111 and is used to inflate and deflate the airbag body 1122, thereby expanding or contracting the airbag body 1122. As shown in Figure 20, the air pump assembly 230 includes an air pump 231 and a valve 232. The air pump 231 is disposed within the installation space 2111 and is used to generate airflow to inflate and deflate the airbag body 1122. The valve 232 is connected to the air pump 231 and is in communication with the through hole 2013 and the air pump 231, respectively. The valve 232 is used to control the flow of the airflow generated by the air pump 231. In this embodiment, when there are two vents 2115, the valve 232 can be disposed between the two vents 2115 and be in communication with the ventilation spaces 2012 of the two vents 2115. The following description only illustrates the structure in which the valve 232 cooperates with the two vents 2115.

[0141] As shown in Figures 21 and 22, the air pump 231 may include a connecting structure 2311 and an air pump body 2312. The connecting structure 2311 is used to mount the air pump body 2312 and is connected to the frame portion 2114 to be fixed within the mounting space 2111. The connecting structure 2311 also has an air cavity 23111 that connects the valve 232 and the air pump body 2312. The air pump body 2312 is disposed on the connecting structure 2311 and is used to generate airflow and, under the control of the valve 232, inflate and deflate the airbag body 1122 to achieve expansion or contraction of the airbag body 1122.

[0142] Specifically, the connection structure 2311 includes a support plate 23112 and a cover plate 23113. The support plate 23112 is disposed within the installation space 2111 and connected to the frame portion 2114. The air pump body 2312 is disposed on one side of the support plate 23112. The support plate 23112 also defines an air hole 23112a that connects the air pump body 2312 with the side of the support plate 23112 facing away from the air pump body 2312. The cover plate 23113 is disposed on the side of the support plate 23112 facing away from the air pump body 2312 and, together with the support plate 23112, encloses an air cavity 23111 that is connected to the air hole 23112a. In this embodiment, airflow generated by the air pump body 2312 can enter the air cavity 23111 through the air hole 23112a and be further conducted through the air cavity 23111 to the valve 232.

[0143] Furthermore, the valve 232 is disposed on a side of the cover plate 23113 facing away from the carrier plate 23112 and communicates with the air cavity 23111. The orthographic projection of the valve 232 on the carrier plate 23112 and the orthographic projection of the air pump body 2312 on the carrier plate 23112 are spaced apart, allowing the valve 232 and the air pump body 2312 to be offset in the thickness direction of the meter header mechanism 200, thereby facilitating a reduction in the stacking height of the valve 232, the air pump body 2312, and the connecting structure 2311. Furthermore, a mounting hole 23113a is defined on a side of the cover plate 23113 facing away from the carrier plate 23112, and the mounting hole 23113a communicates with the air cavity 23111. The air inlet 2321 of the valve 232 can be inserted into the mounting hole 23113a to achieve communication between the valve 232 and the air cavity 23111. In addition, a seal 23114 may be provided between the wall of the mounting hole 23113a and the air inlet portion 2321. The seal 23114 may have an interference fit with the air inlet portion 2321 to improve the sealing performance at the connection between the air inlet portion 2321 and the cover plate 23113. In this embodiment, the seal 23114 may be an annular structure made of materials such as silicone, rubber, or soft plastic.

[0144] As shown in Figures 18 and 23, the valve 232 is arranged between the two vents 2115, and the valve 232 is provided with air outlet portions 2322 on the opposite sides facing the two vents 2115, and the air outlet portions 2322 can be respectively connected to the bosses 21154 of the two vents 2115, and respectively communicated with the through holes 2013 of the two bosses 21154. The following only takes the cooperation between a single air outlet portion 2322 and the vent 2115 as an example for explanation. The air pump assembly 230 includes a hose 233, one end of which can be connected to the air outlet portion 2322 (e.g., sleeved on the air outlet portion 2322), while the other end of the hose 233 extends into the receiving groove 21155 and is connected to the boss 21154 (e.g., sleeved on the boss 21154), thereby connecting the air outlet portion 2322 and the through hole 2013. This allows air to enter the ventilation space 2012 through the air outlet portion 2322, the hose 233, and the through hole 2013. In this embodiment, the valve 232 is preferably a three-way valve, respectively mating with the two vents 2115. The hose 233 can be interference-fitted with the air outlet portion 2322 and the boss 21154, respectively, to improve the sealing of the connection between the hose 233, the air outlet portion 2322, and the boss 21154.

[0145] Optionally, in order to power the valve 232, the valve 232 may also be connected to the electrical connector 223. Specifically, when there are two vents 2115, since the electrical connector 223 needs to be connected to the support plates 221 on both vents 2115 at the same time, the electrical connector 223 may cover the area between the two vents 2115. Based on this, the valve 232 may also be disposed in the area where the electrical connector 223 is located between the two vents 2115, so that the electrical connector 223 may also power the valve 232. Compared to a solution in which the valve 232 is independently powered, this arrangement helps reduce the amount of wiring within the installation space 2111, thereby reducing costs. In this embodiment, since the valve 232 is disposed on the electrical connector 223, an air inlet 2321 communicating with the air cavity 23111 may be provided on the side of the valve 232 facing away from the electrical connector 223.

[0146] Please refer to Figures 24 to 25 in conjunction with Figure 14. Figure 24 is a structural schematic diagram of the unlocking component 240 in Figure 14, and Figure 25 is a partial cross-sectional structural schematic diagram of the wearable device 10 along XI-XI in Figure 1.

[0147] As shown in Figures 14 and 24-25, the unlocking assembly 240 is slidably disposed within the slide groove 2113 and can slide in the thickness direction of the watch header mechanism 200. When the latch portion 1214 is inserted into the slot 2112, the unlocking assembly 240 is pushed against by the latch portion 1214 to avoid insertion. Furthermore, once the latch portion 1214 is fully inserted, the unlocking assembly 240 can be reset and snapped into the latch groove 12141 to engage with the latch portion 1214. Furthermore, the unlocking assembly 240 is exposed on the side of the rear cover 212 facing away from the frame portion 2114 and can be withdrawn from the latch groove 12141 by a user to release the engagement with the latch portion 1214. This arrangement enables the unlocking assembly 240 to achieve a detachable connection between the latch portion 1214 and the watch header mechanism 200. The structure of the unlocking assembly 240 is further described below.

[0148] The unlocking assembly 240 includes a sliding member 241 and an elastic member 242. The sliding member 241 is disposed within the slide groove 2113 and can slide within the slide groove 2113 along the thickness direction of the watch header mechanism 200. Part of the sliding member 241 is also located within the slot 2112. When the latch portion 1214 is inserted into the slot 2112, the sliding member 241 is displaced by the latch portion 1214. Once the latch portion 1214 is fully inserted, the sliding member 241 can return to its original position, locking into the slot 12141 and engaging with the latch portion 1214. The sliding member 241 is also disposed through the rear cover 212 and exposed on the side of the rear cover 212 facing away from the frame portion 2114. A user can press the sliding member 241 on the rear cover 212 to release the sliding member 241 from the slot 12141, thereby releasing the locking state between the sliding member 241 and the latch portion 1214. The elastic member 242 is arranged between the sliding member 241 and the bottom wall of the sliding groove 2113, and when the sliding member 241 is pushed by the locking portion 1214 or pressed by the user, the elastic member 242 can be elastically deformed by the sliding member 241 to provide elastic force to drive the sliding member 241 to reset.

[0149] It is understandable that the structure of the aforementioned unlocking component 240 is merely an example. In some embodiments, the structure of the unlocking component 240 may not be limited thereto. It is only necessary that the unlocking component 240 can cooperate with the buckle portion 1214 to achieve a detachable connection. This embodiment does not limit this.

[0150] The wearable device 10 provided in the present application is provided with an air path 201 on the housing assembly 210 that is connected to the air pump assembly 230 and the outside of the housing assembly 210. The air path 201 can also be connected to the strap mechanism 100 when the housing assembly 210 is detachably connected to the strap mechanism 100, so that the detachable connection between the housing assembly 210 and the strap mechanism 100 can also play a role in fixing the connection between the strap mechanism 100 and the air path 201. With such a configuration, the fixing structure required for maintaining the connection between the strap mechanism 100 and the air path 201 on the housing assembly 210 can be omitted, thereby increasing the available space of the header mechanism 200 and reducing the limitations on the design of the header mechanism 200 and the layout of internal components due to insufficient space.

[0151] The above descriptions are only some embodiments of the present application and do not limit the scope of protection of the present application. Any equivalent device or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the scope of patent protection of this application.
