Description

[0001] This application is a divisional application based on application number 202011594117.9, filed on December 29, 2020, by Wuhan Tianma Microelectronics Co., Ltd. and its Shanghai branch, entitled "Wristband and Wristwatch". Technical Field

[0002] This invention relates to the field of display technology, and in particular to a wristband and a watch. Background Technology

[0003] With the continuous development and advancement of technology, various watches are becoming increasingly popular, especially smartwatches. These watches not only satisfy the wearer's need to tell time, but also provide feedback on parameters such as physical condition information, making them increasingly favored by users. Consequently, the requirements for the user experience of smartwatches are also getting higher and higher.

[0004] For example, the required tightness of a watch strap varies depending on the wearer's state of mind. When exercising, the strap needs to be tighter to prevent discomfort from excessive movement. Conversely, when not exercising, the strap should be looser for comfort.

[0005] Existing wristbands, in order to meet the wearer's requirements for wristband laxity in different states, are mainly adjusted by adjusting the length of the wristband around the wearer's wrist, which is complicated and not conducive to adjusting the wristband laxity. Summary of the Invention

[0006] This invention provides a wristband and a wristwatch. The wristband can adjust its looseness according to the wearer's movement state. It is easy to operate and facilitates the adjustment of the wristband's looseness.

[0007] On one hand, according to an embodiment of the present invention, a wristband is provided, comprising: a wristband body for wearing on a wearer, the wristband body including a strap body and an inflatable bladder disposed on the strap body, the wall portion surrounding the inflatable bladder being provided with a release structure communicating with the inner cavity of the inflatable bladder to release gas inside the inflatable bladder; an inflation device disposed on the wristband body, the inflation device including an inflation component and a driving component, the inflation component communicating with the inflatable bladder, the driving component moving with the wearer and providing power to the inflation component to inflate the inflatable bladder.

[0008] On the other hand, according to an embodiment of the present invention, a wristwatch is provided, including the wristband described above; a dial, which is connected to the wristband and can be enclosed together with the wristband to form a closed ring, with a vent hole facing the closed ring.

[0009] According to embodiments of the present invention, a wristband and a wristwatch are provided. The wristband includes a wristband body and an inflation device. The wristband body has a strap body and an inflation bladder disposed on the strap body. The inflation device includes an inflation component and a driving component. When the wristband is used in a wristwatch and placed on the wearer, the wristband adjusts its looseness according to the wearer's state. For example, when the wearer moves, the driving component moves accordingly and provides power to the inflation component to inflate the inflation bladder, making the volume of the inflation bladder larger and ensuring that the wristband is tighter on the wearer's wrist. When the wearer is in a quiet state, the gas inside the inflation bladder can be released using a release structure communicating with the inner cavity of the inflation bladder to loosen the wristband. The operation is simple and facilitates the adjustment of the wristband's looseness. Attached Figure Description

[0037] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. Numerous specific details are set forth in the following detailed description in order to provide a thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention may be practiced without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of the invention by illustrating examples of the invention. In the accompanying drawings and the following description, at least some well-known structures and techniques have not been shown in order to avoid unnecessarily obscuring the invention; and, for clarity, the dimensions of some structures may be exaggerated. Furthermore, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0038] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the wristband and watch of the present invention. It should also be noted in the description of the present invention that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0039] As wristwatches become increasingly popular, wearers have higher and higher demands for the wristwatch experience. For example, the ease of adjusting the wristband's tightness under different sports conditions is an important factor when purchasing a watch. Most existing watches adjust the tightness of their wristbands using a clasp system, adjusting the length around the wearer's wrist. This method is complex and not conducive to adjusting the tightness. Some watches use an active air-inflating system to adjust the tightness. This mainly uses an air pump or other power source to introduce or remove air from the wristband as needed. While this method achieves the desired tightness adjustment, it requires an external power source, which consumes electrical energy and requires a corresponding control system, making the overall structure of the wristband complex and costly.

[0040] To address the aforementioned technical problems, this invention provides a novel wristband that adjusts its slack according to the wearer's movement, offering ease of operation and convenient adjustment. For a better understanding of this invention, the following description... Figures 1 to 17 The wristband and wristwatch according to embodiments of the present invention will be described in detail.

[0041] like Figures 1 to 5 As shown, Figure 1 A schematic diagram of the structure of a wristband 100 according to an embodiment of the present invention is shown. Figure 2This diagram illustrates the usage state of the wristband 100 in a relaxed state according to an embodiment of the present invention. Figure 3 This diagram illustrates the usage state of the wristband 100 in a tightened state according to an embodiment of the present invention. Figure 4 as well as Figure 5 As shown, Figure 4 A top view of a wristband 100 according to an embodiment of the present invention is shown. Figure 5 A schematic diagram of the structure of an inflation device 20 and a mounting frame 30 according to an embodiment of the present invention is shown.

[0042] The wristband 100 provided in this embodiment of the invention includes a wristband body 10 and an inflation device 20. The wristband body 10 is used to be fitted onto a wearer 300. The wristband body 10 includes a strap body 11 and an inflation bladder 12 disposed on the strap body 11. The wall portion surrounding the inflation bladder 12 is provided with a release structure 13 that communicates with the inner cavity of the inflation bladder 12 to release the gas inside the inflation bladder 12. The inflation device 20 is disposed on the wristband body 10. The inflation device 20 includes an inflation component 21 and a driving component 22. The inflation component 21 communicates with the inflation bladder 12. The driving component 22 moves with the wearer 300 and provides power to the inflation component 21 to inflate the inflation bladder 12.

[0043] The wristband 100 provided in this embodiment of the invention, when used in a wristwatch and mounted on a wearer 300, adjusts its looseness according to the movement state of the wearer 300. When the wearer 300 is in a non-moving state, the gas inside the airbag 12 can be released using the release structure 13, which communicates with the inner cavity of the airbag 12, to loosen the wristband 100. When the wearer moves, the drive component 22 will move accordingly and provide power to the inflation component 21 to inflate the airbag 12, making the airbag 12 larger and ensuring that the wristband 100 fits more snugly on the wearer's wrist. This operation is simple and facilitates the adjustment of the wristband 100's looseness.

[0044] Furthermore, the wristband 100 provided in this embodiment of the invention utilizes the kinetic energy obtained by the inflator 20 to provide power to the inflator 21 by following the wearer 300, thereby meeting the inflation requirements of the airbag 12. It does not require an external air pump or other power source, and therefore does not require a corresponding control system to control the power source. The overall structure of the wristband 100 is simple and the cost is low.

[0045] In some alternative embodiments, the wristband 100 provided in this embodiment of the invention may have its body 11 made at least partially of a flexible strip, and the flexible strip has a predetermined deformation capability under external force. Optionally, the entire body 11 may be made of flexible strip. Of course, in some embodiments, the body 11 may only be made of flexible strip at the location where the inflatable bladder 12 is provided.

[0046] As an alternative implementation, the wristband body 10 may have two opposite free ends in its own length direction. When used in a wristwatch, the two opposite free ends may be used to connect with the dial 200 and together form a closed loop.

[0047] As an optional implementation, the wristband 100 provided in this embodiment of the invention has an inflatable bladder 12 disposed inside the wristband body 11, which divides the wristband body 11 into a first split 11a and a second split 11b disposed opposite to each other. In the arrangement direction of the first split 11a and the second split 11b, the wall thickness of the first split 11a is smaller than the wall thickness of the second split 11b. When used for a wristwatch and disposed on a wearer 300, the first split 11a faces the wearer 300 and the second split 11b faces away from the wearer 300.

[0048] like Figure 2 As shown, when the air bladder 12 of the wristband 100 is not inflated, a gap can be formed between the first part 11a formed on the main body 11 and the wearer 300, at which time the wristband 100 is in a relaxed state.

[0049] like Figure 3 As shown, when the wearer 300 is in motion, such as during running, the drive component 22 moves with the wearer 300 and provides power to the inflation component 21 to inflate the airbag 12. When gas enters the airbag 12, the volume of the airbag 12 will increase, and at the same time, it will compress the first part 11a and the second part 11b, providing a force to the first part 11a and the second part 11b to move away from each other. Since the wall thickness of the first part 11a is less than that of the second part 11b, the first part 11a is less resistant to external forces than the second part 11b. The gas that is filled in will move towards the side where the first part 11a is located in advance. The first part 11a will deform in a direction away from the second part 11b to contact the wearer 300, reduce or eliminate the gap between it and the wearer 300, so that the wristband 100 is in a tightened state, which satisfies the automatic tightening requirement of the wearer 300 for the wristband 100 from the non-movement state to the movement state.

[0050] like Figure 6 As shown, Figure 6 yes Figure 1Enlarged view at point A. In some optional embodiments, the release structure 13 includes a vent 131, which communicates with the inner cavity of the air bladder 12 and faces the wearer 300. By including the vent 131 in the release structure 13, the gas inside the air bladder 12 can slowly leak out. Since the vent 131 faces the wearer 300, when the wearer 300 is in motion, the inflation device 20 inflates the air bladder 12, causing it to expand. The vent 131 temporarily adheres to the wearer 300, maintaining the tightness of the wristband 100. When the wearer 300 is not in motion, the drive component 22 also stops providing power to the inflation component 21, and the gas inside the air bladder 12 slowly leaks out under the action of the vent 131, automatically loosening the wristband 100.

[0051] In some alternative embodiments, the air leakage hole 131 can be provided on the first split 11a and communicate with the air bag 12. The number of air leakage holes 131 can be set according to parameters such as the size of the air bag 12 and the air leakage rate requirement. There can be one or more. When there are more than two, they can be distributed at intervals in the direction surrounding the wearer 300.

[0052] See Figures 4 to 6 As an optional implementation, the wristband 100 provided in various embodiments of the present invention includes a driving component 22 comprising a rotatably connected adapter 221 and a moving component 222. One end of the adapter 221 opposite to the moving component 222 is connected to the inflation component 21. The moving component 222 moves with the wearer 300 and drives the inflation component 21 to extend and retract via the adapter 221. With the above-described form, the driving component 222 can connect the moving component 222 to the inflation component 21 via the adapter 221, allowing the kinetic energy generated by the movement of the moving component 222 and the wearer 300 to be converted into the extension and retraction motion of the inflation component 21, reliably meeting the inflation requirements of the airbag 12.

[0053] In some optional embodiments, the wristband 100 provided by this invention has a moving member 222 that can be rotatably connected to the wristband body 10. The rotation center of the moving member 222 and the wristband body 10, and the rotation center of the adapter 221 and the moving member 222 are spaced apart from each other. The moving member 222 moves with the wearer 300 and rotates relative to the wristband body 10, so as to drive the inflation component 21 to extend and retract via the adapter 221. By making the moving member 222 rotatably connected to the wristband body 10, when the wearer 300 moves, the moving member 222 can rotate a full circle relative to the wristband body 10 with the rotation center of the wristband body 10 as the rotation center, so as to drive the adapter 221 to move along a predetermined trajectory, so as to alternately stretch and compress the inflation component 21 to meet the inflation requirements of the airbag 12.

[0054] As an optional implementation, the moving part 222 may include a turntable 2221 and a swinging part 2222 connected to the turntable 2221. The center of the turntable 2221 is rotatably connected to the wristband body 10 through a first rotating shaft 2223. The swinging part 2222 moves with the wearer 300 and drives the turntable 2221 to rotate around the first rotating shaft 2223. The adapter 221 is rotatably connected to the turntable 2221 through a second rotating shaft 2224. The second rotating shaft 2224 and the first rotating shaft 2223 are spaced apart from each other. The moving part 222 adopts the above-described structure, which allows the wearer 300 to move in different directions. This allows the moving part 222 to move in multiple directions of the wearer 300, so that the whole formed by the swing part 2222 and the turntable 2221 can rotate around the first rotating shaft 2223 as the rotation center relative to the wristband body 10. Then, the second rotating shaft 2224 drives the adapter 221 to move, thereby stretching and compressing the inflatable part 21.

[0055] In some alternative embodiments, the swinging part 2222 includes a swing arm 2222a and a pendulum 2222b. One end of the swing arm 2222a is connected to the turntable 2221, and the other end of the swing arm 2222a protrudes radially from the turntable 2221 and is connected to the pendulum 2222b. With the above-described structure, the swinging part 2222 can amplify the kinetic energy obtained by the wearer 300, increase the driving force on the adapter 221, and thus more easily achieve the stretching and compression of the inflation component 21, ensuring the inflation effect of the airbag 12.

[0056] Optionally, the swing arm 2222a can be a rod structure and be fixedly connected to the turntable 2221. The pendulum 2222b can be a spherical body and can be made of a high-density material to ensure that it has a greater weight while occupying a smaller volume.

[0057] In some alternative embodiments, the adapter 221 may be a rod structure, which is simple in structure and facilitates the transfer of kinetic energy between the moving part 222 and the inflatable part 21.

[0058] As an optional implementation, the inflation component 21 includes a bellows with an air inlet and an inflation port communicating with the inflation bladder 12. The end of the bellows is connected to the drive component 22. The bellows-shaped inflation component 21 has a simple structure and is easy to stretch and compress. Optionally, the end of the bellows can be connected to the adapter 221 of the drive component 22.

[0059] As an optional implementation, in the wristband 100 provided in this embodiment of the invention, when the release component includes an air vent 131, the radial dimension of the interface between the inflation component 21 and the air bladder 12 is greater than or equal to the radial dimension of the air vent 131. Through this arrangement, when the wearer 300 is in motion, the inflation rate of the inflation device 20 on the air bladder 12 is greater than the deflation rate of the air vent 131, ensuring effective inflation of the air bladder 12 during wearer 300 movement and meeting the tightening requirements of the wristband 100 during wearer 300 movement.

[0060] In some optional embodiments, the diameter of the air vent 131 of the wristband 100 provided in this embodiment of the invention is any value between 0.05mm and 0.1mm, including both 0.05mm and 0.1mm, and optionally 0.03mm. The diameter of the interface between the inflation component 21 and the inflation bladder 12 is any value between 1mm and 1.5mm, including both 1mm and 1.5mm, and optionally 1.2mm. The air vent 131 and the interface using the above dimensions reliably ensure that the wristband 100 automatically adjusts its slack according to the movement state of the wearer 300, thereby improving the user experience.

[0061] As an optional implementation, the wristband 100 provided in this embodiment of the invention includes an inflation device 20 that further includes a connecting pipe 24. The connecting pipe 24 connects the inflation component 21 and the inflation bladder 12. A second control valve 25 is provided within the connecting pipe 24, and the second control valve 25 allows unidirectional flow from the inflation component 21 to the inflation bladder 12. This arrangement facilitates the connection between the inflation bladder 12 and the inflation component 21, while also preventing the inflation component 21 from drawing back the gas from the inflation bladder 12 when stretched, thus ensuring the effective inflation of the inflation bladder 12.

[0062] In some optional embodiments, the wristband 100 provided in this invention further includes a mounting frame 30 disposed on the wristband body 10, and the inflation device 20 is integrated into the mounting frame 30 and connected to the wristband body 10 through the mounting frame 30. By providing the mounting frame 30, the inflation component 21, the driving component 22, and the connecting pipe 24 of the inflation device 20 can all be integrated into the mounting frame 30, improving the overall integration of the inflation device 20, facilitating the disassembly, assembly, and maintenance of the inflation device 20, and ensuring the overall aesthetic performance of the wristband 100.

[0063] As an optional implementation, the wristband 100 provided in this embodiment of the invention can have a rectangular frame structure as a whole for its mounting frame 30. Of course, in some embodiments, it can also be a ring, ellipse or other polygonal frame structure, as long as it can meet the integration requirements of the inflation device 20.

[0064] In some alternative embodiments, the mounting frame 30 and the belt body 11 can be connected to each other by adhesive bonding. In this case, the belt body 11 can be made entirely of flexible belt. It is understood that adhesive bonding between the mounting frame 30 and the belt body 11 is only an optional connection method, but is not limited to this connection method.

[0065] like Figure 7 As shown, Figure 7 A partial structural schematic diagram of a wristband 100 according to another embodiment of the present invention is shown. In some embodiments, the band body 11 may have a flexible portion 111 and a rigid fixing portion 112 connected to each other, with the inflatable bladder 12 located in the flexible portion 111, and the mounting frame 30 detachably connected to the rigid fixing portion 112. This configuration satisfies the deformation requirements of the band body 11 under the action of the inflatable bladder 12, thereby allowing for adjustment of the wristband 100's slackness. The rigid fixing portion 112 facilitates the detachable connection between the mounting frame 30 and the rigid fixing portion 112 using bolts, rivets, or other detachable connection methods, thus facilitating the disassembly, assembly, and maintenance of the inflation device 20.

[0066] As an optional implementation, the wristband 100 provided in the above embodiments of the present invention is illustrated by taking the example of the air bladder 12 being disposed inside the wristband body 11. This is an optional implementation. In some embodiments, the air bladder 12 may also be formed outside the wristband body 11.

[0067] like Figure 8 as well as Figure 9 As shown, Figure 8 This diagram illustrates the usage state of the wristband 100 in a relaxed state, according to yet another embodiment of the present invention. Figure 9 This diagram shows the usage state of the wristband 100 in the tightened state according to another embodiment of the present invention.

[0068] For example, the wristband body 10 may further include a diaphragm 14, the outer periphery of which is connected to the band body 11 to form an air bladder 12. The thickness of the diaphragm 14 is less than the wall thickness of the band body 11. The diaphragm 14 is positioned facing the wearer 300 and the band body 11 is positioned away from the wearer 300. A release structure 13 is disposed on the diaphragm 14. By disposing the diaphragm 14 outside the band body 11 and connecting the outer periphery of the diaphragm 14 to the band body 11, an air bladder 12 can also be formed. The inflation component 21 of the inflation device 20 can communicate with the air bladder 12. Alternatively, a connection hole communicating with the air bladder 12 can be provided on the band body 11, so that the inflation component 21 communicates with the air bladder 12 through the connection hole on the band body 11, thereby allowing the drive component 22 to inflate the air bladder 12 under the action of the wearer 300.

[0069] like Figure 8 As shown, when the wristband 100 provided in this embodiment of the invention is used in a wristwatch and disposed on the wearer 300, a gap may be formed between the diaphragm 14 and the wearer 300 in the initial state. Figure 9 As shown, when the wearer 300 moves, the inflator 21 is driven by the inflator 21 to inflate the air bladder 12 under the follow-up action of the inflator 20's drive component 22, increasing the volume of the air bladder 12. Since the thickness of the diaphragm 14 is less than the thickness of the strap body 11, the diaphragm 14 is less resistant to external forces than the strap body 11. Consequently, when the gas in the air bladder 12 increases, the diaphragm 14 will deform and move towards the wearer 300, reducing or eliminating the gap between the diaphragm 14 and the wearer 300, thus automatically adjusting the slack of the wristband 100 as the wearer 300 moves.

[0070] Since the release structure 13 is located on the diaphragm body 14, when the gas inside the inflation bladder 12 continuously increases, causing the diaphragm body 14 to adhere to the wearer 300, the air leakage hole 131 of the release structure 13 will adhere to the wearer 300, ensuring the wristband 100 is in a tightened state. When the wearer 300 changes from a moving state to a non-moving state, the inflation device 20 will stop inflating the inflation bladder 12, allowing the gas inside the inflation bladder 12 to slowly leak through the air leakage hole 131, returning to a loosened state.

[0071] like Figure 10 as well as Figure 11 As shown, Figure 10 This diagram illustrates the usage state of the wristband 100 in a relaxed state according to another embodiment of the present invention. Figure 11 This diagram illustrates the usage state of the wristband 100 in a tightened state according to another embodiment of the present invention.

[0072] As an optional implementation, the wristband 100 provided in this embodiment of the invention has two or more air bladders 12, which are spaced apart on the band body 11 and adjacent air bladders 12 are interconnected. This arrangement disperses the air bladders 12 and connects adjacent air bladders 12, thereby increasing the inflation and deflation rates over the same span.

[0073] Optionally, when there are two or more airbags 12 that are connected to each other, the number of release structures 13 can be set according to requirements, and no specific limit is made here.

[0074] It is understood that the wristband 100 provided in the above embodiments of the present invention is illustrated by taking the rotating connection between the moving member 222 and the wristband body 10 during the process of following the movement of the wearer 300 as an example. This is an optional method, but it is not limited to the above method.

[0075] like Figure 12 As shown, Figure 12 A schematic diagram of the inflatable device 20 and the mounting frame 30 in another embodiment of the present invention is shown. In some embodiments, the moving member 222 can be movably connected to the wristband body 10, and the moving member 222 and the wearer 300 can move relative to the wristband body 10 to drive the inflatable component 21 to extend and retract. Similarly, the extension and retraction of the inflatable component 21 can be driven by the following action of the moving member 222 and the wearer 300, thereby meeting the inflation requirements of the airbag 12 and achieving the tightening of the wristband 100.

[0076] As an optional implementation, when the moving member 222 is movably connected to the wristband body 10, the inflation device 20 further includes a guide member 23 disposed on the wristband body 10. The guide member 23 extends along the extension and retraction direction of the inflation member 21. The moving member 222 includes a sliding portion that cooperates with the guide member 23 and can slide back and forth in the extension direction of the guide member 23. The guide member 23 provides constraint on the movement of the moving member 222, allowing it to move along the extension and retraction direction of the inflation member 21 during its movement with the wearer 300, thereby ensuring the driving effect on the inflation member 21.

[0077] In some alternative embodiments, the guide component 23 can adopt the structure of a guide rail. Correspondingly, the sliding part of the moving component 222 can be a structure that matches the shape of the guide rail and can slide and engage. The structure is simple and facilitates the following requirements of the wearer 300.

[0078] It is understood that the wristband 100 provided in the above embodiments is an example of driving a group of inflatable components 21 by the driving component 22. This is an optional implementation method, but it is not limited to the above method.

[0079] like Figure 13 As shown, Figure 13 A schematic diagram of the structure of the inflation device 20 and the mounting frame 30 in another embodiment of the present invention is shown. In some embodiments, the inflation components 21 can also be arranged in pairs, and the moving member 222 is connected to each inflation component 21 through a connector 221. The two pairs of inflation components 21 can be driven simultaneously by the same moving member 222. For example, the two sets of inflation components 21 can be symmetrically distributed on both sides of the moving member 222 and connected to the moving member 222 respectively through the connector 221. When the moving member 222 moves with the wearer 300 and stretches one inflation component 21, it will compress the other inflation component 21, so as to realize the simultaneous extension and contraction of the two inflation components 21, and enable the paired inflation components 21 to provide constraints on the movement path of the moving member 222, thereby improving the utilization rate of the kinetic energy obtained by the moving member 222 from moving with the wearer 300.

[0080] Optionally, the paired inflatable components 21 can be connected to the same inflatable bladder 12. Of course, when there are two or more inflatable bladders 12, the paired inflatable components 21 can also be connected to different inflatable bladders 12, as long as the needs of each inflatable bladder 12 can be met.

[0081] Optionally, when the moving part 222 simultaneously drives the paired inflatable parts 21 to extend and retract, the moving part 222 can be a block-shaped structure. Of course, in order to reduce frictional loss, the moving part 222 can also be a spherical structure, and a hinge lug can be provided on the outer peripheral surface of the moving part 222 to facilitate rotatable connection with the corresponding adapter 221.

[0082] It is understood that the wristband 100 provided in the above embodiments of the present invention is illustrated by taking the form of a corrugated tube as the telescopic component. This is an optional implementation method, but it is not limited to the above method.

[0083] like Figure 14 As shown, Figure 14 A schematic diagram of the inflator 20 and mounting frame 30 in another embodiment of the present invention is shown. In some embodiments, the inflator 21 may include a telescopic cylinder, the cylinder body of which has an air inlet and an inflation port communicating with the airbag 12, and the cylinder rod of the telescopic cylinder is connected to the drive component 22. The telescopic cylinder form of the inflator 21 can also meet the inflation requirement of the airbag 12 under the drive of the moving component 222. When the inflator 21 adopts the telescopic cylinder structure, its cylinder rod can be connected to the adapter 221; in some optional examples, the two can be an integral structure.

[0084] It is understood that the wristband 100 provided in the above embodiments of the present invention, with the release structure 13 exemplified by including an air vent 131, is an optional implementation. In some embodiments, the release structure 13 may also include a first control valve, which communicates with the inner cavity of the inflation bladder 12. The gas in the inflation bladder 12 can be released or maintained by controlling the opening and closing of the first control valve, ensuring the adjustment of the wristband 100's slack. Optionally, the first control valve may be a solenoid valve, which is easy to control.

[0085] It is understood that the wristband 100 provided in the above embodiments is illustrated by taking the wristband body 11 as having two opposite free ends as an example. This is only an optional implementation method, but is not limited to the above method.

[0086] like Figure 15 As shown, Figure 15A schematic diagram of the structure of a wristband 100 according to another embodiment of the present invention is shown. In some embodiments, the band body 11 can be made into a closed loop, and when used in a wristwatch, the dial 200 can be attached to the wristband body 10. Of course, a mounting base 40 can be provided on the band body 11 for mounting the dial 200.

[0087] like Figure 16 as well as Figure 17 As shown, Figure 16 A schematic diagram of the structure of a wristwatch according to an embodiment of the present invention is shown. Figure 17 yes Figure 16 Top view of the structure shown.

[0088] On the other hand, embodiments of the present invention also provide a wristwatch, which includes a wristband 100 and a dial 200 as described in the above embodiments. The dial 200 is connected to the wristband 100 and can be together with the wristband 100 to form a closed loop 400. Optionally, the release structure 13 can be disposed toward the closed loop 400.

[0089] The wristwatch provided in this embodiment of the invention includes the wristband 100 provided in the above embodiments. Therefore, it can automatically adjust the looseness of the wristband 100 according to the movement state of the wearer 300, which is beneficial for adjusting the looseness of the wristband 100. Furthermore, the correspondingly designed dial 200 can be used to display necessary information, such as time information, location information, the wearer's heart rate and blood pressure, and step count, resulting in a high level of user experience.

[0090] Although the invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict. The invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
