Description

Technical Field

[0001] This application relates to the field of wearable technology, and more particularly to an adjustment mechanism, a wristband, and a wearable device. Background Technology

[0002] Currently, the length of common watch straps can be adjusted by removing or adding links. However, this method of adjustment cannot achieve fine-tuning of the strap length, resulting in the strap being too long or too short for the user before and after removing links. It cannot accurately fit the wrist and cannot achieve the best wearing experience.

[0003] Therefore, an adjustment mechanism needs to be designed to allow for fine-tuning of the wristband length while it is being worn, precisely fitting the wearer's wrist size and improving the user experience. Utility Model Content

[0004] This application provides an adjustment mechanism, a wristband, and a wearable device, which solves the problem of difficulty in adjusting the length of wearable devices.

[0005] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0006] A first aspect of this application provides an adjustment mechanism for connecting a strap. The adjustment mechanism includes a first housing and an adjustment member. The first housing includes a base plate and a first side plate connected to the base plate. The base plate extends along a first direction and has multiple grooves arranged parallel to the first direction. The first side plate has a first guide groove extending parallel to the first direction, wherein the first direction is the extension direction of the connecting strap. The adjustment member includes a snap-fit ​​element and a first button. One end of the first button extends out of the first guide groove and is slidably connected to the first guide groove. When one end of the first button moves closer to or away from the first housing, the snap-fit ​​element moves closer to or away from the groove. Thus, one end of the first button extends out of the first guide groove, i.e., one end of the first button protrudes from the first side plate, allowing the first button to be pressed during wear, causing the snap-fit ​​element to move away from the groove. In addition, users can push the adjustment component while pressing the first button, so that the adjustment component can move back and forth relative to the first housing in the first direction. In this way, the wristband length can be finely adjusted while wearing the device, making the operation simpler and improving the user experience.

[0007] In one optional embodiment, the base plate includes a first end and a second end disposed opposite to each other. The adjusting member slides along the direction from the first end to the second end to increase the length of the wristband, and slides along the direction from the second end to the first end to decrease the length of the wristband. The groove includes a first inner wall and a second inner wall, the first inner wall being closer to the first end than the second inner wall, and the angle between the first inner wall and the first direction being smaller than the angle between the second inner wall and the first direction. Therefore, increasing the length of the wristband requires pressing a button to push the adjusting member, while decreasing the length of the wristband does not require pressing a button to push the adjusting member. The difficulty in extending the wristband is greater than the difficulty in shortening it, making the wristband less prone to loosening after wearing, preventing accidental stretching that could cause the wristband to fall off, and improving stability and safety.

[0008] In one optional embodiment, the adjusting member further includes a second housing. The latching member includes a latch and a latching portion. The latch is located within the second housing and connected to the latching portion. The other end of the first button extends into the second housing and engages with the latch. When the first button moves relative to the second housing, the latch causes the latch to move away from or towards the recess. Thus, by operating the button, the latching portion of the latching member can be moved out of the recess, and by pushing the adjusting member, the latching portion can be moved from one recess to another, facilitating the adjustment of the wristband length by moving the adjusting member as needed.

[0009] In one optional implementation, the pressing direction of the first button is perpendicular to the first direction. This facilitates button operation while the device is worn, simplifying operation, conforming to user habits, and improving the user experience.

[0010] In one optional embodiment, the end of the first button that is inserted into the latch has a first inclined surface. The first inclined surface is disposed away from the latching portion and at an angle to the first direction, and the first inclined surface abuts against the latch. Thus, by providing the first inclined surface, when the first button moves relative to the second housing, the latch can cause the latching portion to move away from or closer to the groove.

[0011] In one alternative embodiment, the latch includes a second inclined surface adapted to the shape of the first inclined surface. Thus, by engaging the first and second inclined surfaces, a smaller force is required to move the latch upwards when the button is operated, thereby dislodging the locking portion from the groove.

[0012] In one optional embodiment, the adjusting member further includes an elastic element, which is elastically connected between the side of the latch facing away from the base plate and the second housing. Thus, when the user operates the button to move the latch away from the groove, the elastic element is compressed, and the latch experiences a spring force from the elastic element towards the groove. When the user does not press the button, the spring force from the elastic element causes the latch to move towards the groove. By providing the first elastic element, the movement of the latch is facilitated.

[0013] In one optional embodiment, the first housing further includes: a second side plate, the first side plate and the second side edge being disposed on opposite sides of the base plate, the second side plate being provided with a second guide groove; the adjusting member further includes: a second button, one end of the second button extending into the second housing and engaging with the latch, the other end of the second button extending out of the second guide groove; the latch includes a first segment, a second segment, and a third segment fixedly connected in sequence, the second segment of the latching part facing the bottom, the elastic member being located in the second segment; the first button is engaged with the first segment, and the second button is engaged with the third segment. Thus, through the combined action of the first button and the second button, the movement of the latching part is made smoother, reducing the difficulty of operation.

[0014] In one optional embodiment, the second housing and the first housing form a first cavity, the first cavity including a first space, a second space, and a third space connected in sequence. The latch is located in the second space, the first button passes through the first space and abuts against the first segment, and the second button passes through the third space and abuts against the third segment. Thus, the structure of the button matches the structure of the latch, resulting in a more compact structure, balanced force distribution, and facilitating the miniaturization of the adjustment component.

[0015] In one optional embodiment, the first button includes: a connector, a first support portion, and a second support portion. The first support portion passes through the first guide groove and the first cavity, and the second support portion is located in the first cavity. The first support portion and the second support portion are stacked within the first cavity, and the first support portion and the second support portion are detachably connected by the connector. This breaks the button down into multiple parts, reducing assembly difficulty.

[0016] In one optional embodiment, the second housing includes a third guide groove, and the connector passes through the third guide groove, allowing the connector to move within the third guide groove. Thus, when the first button is operated, the first connector can move within the third guide groove, enabling the first button to move relative to the second housing. Furthermore, the third guide groove confines the movement of the first button within the second housing to a certain range, which helps prevent the first button from detaching from the second housing.

[0017] In one optional embodiment, the adjusting member further includes a first connecting portion and a second connecting portion, which are fixed to opposite sides of the second housing. The first housing includes a first guide rail and a second guide rail, which are located on opposite sides of the base plate. The first connecting portion is slidably connected to the first guide rail, and the second connecting portion is slidably connected to the second guide rail. The first and second connecting portions are used to connect with the connecting strap of the wristband. Thus, the first guide rail can limit the movement direction of the second housing through the first connecting portion, and the second guide rail can limit the movement direction of the second housing through the second connecting portion.

[0018] A second aspect of this application provides a wristband including a connecting strap and an adjustment mechanism as described above, one end of the connecting strap being connected to an adjustment member of the adjustment mechanism. Thus, by employing the aforementioned adjustment mechanism, the wristband length can be finely adjusted while worn, simplifying operation and improving the user experience.

[0019] In one optional embodiment, the wristband includes an opening and closing mechanism connected to one end of the connecting strap and to the first housing of the adjusting mechanism. The opening and closing mechanism is used to open or close the wristband. This facilitates the wearing of the wristband.

[0020] A third aspect of this application provides a wearable device, including a watch body and the aforementioned wristband, the wristband being connected to the watch body. Thus, by employing the aforementioned wristband, the wearable device allows for fine-tuning of the wristband length while worn, simplifying operation and improving the user experience.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0041] In the following description, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0042] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0043] This application provides an electronic device, which can be a smart wearable device, such as a human health monitoring wearable device capable of detecting a user's health vital signs (e.g., heart rate, blood oxygen, blood pressure, sleep, etc.). Examples of such smart wearable devices include smartwatches, smart bracelets, smart glasses, smart helmets, and smart headphones. Alternatively, the electronic device can also be a mobile phone, tablet, laptop, smart home device, virtual reality (VR) electronic device, augmented reality (AR) electronic device, etc. Furthermore, the electronic device can also be a handheld device with wireless communication capabilities, a computing device, or other processing devices connected to a wireless modem, an in-vehicle device, an electronic device in a 5G network, or an electronic device in a future public land mobile network (PLMN), etc. This application does not limit the scope of the application to these specific applications.

[0044] For ease of explanation, the following is based on... Figure 1 The example shown is a wearable device 1. Figure 1 As shown, Figure 1 This is a schematic diagram of a wearable device provided in an embodiment of this application. The wearable device 1 includes a watch body 10 and a wristband 20, which is connected to the watch body 10. The wristband 20 can be bent into a loop structure and worn on the wrist, arm, or other parts of the body, or the loop structure of the wristband 20 can be detached and removed from the wrist to achieve the wearable function.

[0045] This application does not limit the connection method between the watch body 10 and the wristband 20. In some embodiments, the wristband and the watch body can be rotatably connected by a pin, wherein the pin can be connected to the watch body, and the wristband is rotatably connected to the pin, so that the wristband can rotate relative to the watch body, and the wristband and the watch body can rotate to any angle. In other embodiments, the wristband and the watch body can also be fixedly connected, which is not limited in this application.

[0046] The watch body 10 can be used to display time, monitor health data, monitor exercise data, or monitor environmental data, etc., to implement the corresponding functions of the wearable device 1. For example, the wearable device 1 can be a wearable watch, capable of displaying time, keeping time, or announcing the time. A physiological sensor can be installed within the watch body 10 to continuously monitor the user's vital signs, such as heart rate, blood pressure, body temperature, and blood oxygen levels. By continuously monitoring these signs, data on the user's physical condition can be obtained, and appropriate actions can be taken when necessary. A motion sensor can be installed within the watch body 10 to detect the user's movement status, such as steps, acceleration, and angle. By analyzing the user's exercise data, information such as exercise intensity and calories burned can be obtained, and a healthier exercise plan can be recommended. An environmental sensor can be installed within the watch body 10 to detect environmental data such as light, temperature, humidity, and radiation. By analyzing environmental information, the user's environment can be understood, and corresponding adjustments can be made, such as recommending sun-protective glasses or increasing warmth, to provide the user with a more suitable living experience.

[0047] The body 10 can be circular, rectangular, or other shapes.

[0048] In some embodiments, to adjust the length of the wristband 20, it is necessary to remove the wristband 20 from the wrist and adjust its length. For example, the length of the wristband can be adjusted by removing or adding links. However, this adjustment method cannot achieve fine-tuning of the wristband length, resulting in the wristband being too long or too short before and after removing links, failing to accurately fit the wrist and achieve the best wearing experience.

[0049] Therefore, this application provides an improved wristband 20, which includes an adjustment mechanism, allowing the wearer to fine-tune the wristband while wearing it to precisely fit the wearer's wrist size and improve wearing comfort.

[0050] Figure 2 A first-view diagram of a wristband provided in an embodiment of this application. Figure 3 This is a second-view image of a wristband provided as an embodiment of this application. Wherein, as... Figure 2 , Figure 3As shown, the wristband may include a connecting strap 21 and an adjustment mechanism 22. The connecting strap 21 may include a first connecting strap 211 and a second connecting strap 212. No other structural components may be provided between the first connecting strap 211 and the second connecting strap 212. There is no gap between the first connecting strap 211 and the second connecting strap 212, and they are in contact. A watch body may also be provided between the first connecting strap 211 and the second connecting strap 212. This embodiment of the application uses the example of a watch body being provided between the first connecting strap 211 and the second connecting strap 212. One end of the first connecting strap 211 can be connected to the adjustment mechanism 22, and the other end of the first connecting strap 211 can be connected to the watch body. One end of the second connecting strap 212 can be connected to the adjustment mechanism 22, and the other end of the second connecting strap 212 can be connected to the watch body. The connection method between the first connecting strap 211 and the second connecting strap 212 and the watch body and the adjustment mechanism 22 can be a rotatable connection or a fixed connection, etc., which is not limited in this application.

[0051] Understandably, the first connecting strip 211 and the second connecting strip 212 can be made of materials such as soft rubber strip, metal strip, leather belt or woven strip, and this application does not limit the materials of the first connecting strip 211 and the second connecting strip 212.

[0052] Adjustment mechanism 22 is applied to wristband 20 ( Figure 1 As shown), the adjustment mechanism 22 can drive the first connecting strap 211 or the second connecting strap 212 to move (this embodiment of the application takes the adjustment mechanism 22 driving the second connecting strap 212 to move as an example) to adjust the overall length of the wristband 20, adapt to the user's wearing needs in different scenarios, and improve the user's experience.

[0053] Figure 4 This is a schematic diagram illustrating the disassembly structure of a wristband provided in an embodiment of this application. Figure 4 As shown, the adjustment mechanism 22 may include a first housing 23 and an adjustment member 24. The first housing 23 may be connected to one end of the first connecting strap 211, and the adjustment member 24 may be connected to one end of the second connecting strap 212. The adjustment member 24 is slidably connected to the first housing 23 and can slide within the first housing 23.

[0054] Figure 5 This is a schematic diagram of the structure of a first housing provided in an embodiment of this application. Figure 5As shown, the first housing 23 includes at least a base plate 231 and a first side plate 2321 connected to each other, with the base plate 231 extending along a first direction X. The base plate 231 includes a first side parallel to the first direction X, and the first side plate 2321 is connected to the first side of the base plate 231. The base plate 231 has a plurality of grooves 2311, the arrangement of which is parallel to the first direction X. The first direction X can be the extension direction of the connecting strip. It should be noted that there can be a deviation between the first direction X and the extension direction of the connecting strip; it does not need to be completely parallel to the extension direction of the connecting strip. For example, the first direction X only needs to have a component parallel to the extension direction of the connecting strip.

[0055] The number of grooves 2311 is not limited in this embodiment. The number of grooves 2311 is at least two. Exemplarily, the number of grooves 2311 can be two, three, four, or five, etc., and multiple grooves 2311 can be arranged sequentially along the first direction.

[0056] Figure 6 This is a schematic diagram of the structure of an adjusting member provided in an embodiment of this application. Figure 6 As shown, the adjusting member 24 includes a snap-fit ​​member 25. Figure 7B for Figure 7A NN cross-sectional view. Figure 8A This is a schematic diagram of the structure of a snap-fit ​​member in an adjusting component provided in an embodiment of this application. Figure 7B , Figure 8A As shown, the snap-fit ​​component 25 includes a snap-fit ​​portion 251 and a latch 252 connected to each other. The snap-fit ​​portion 251 is a protruding structure. The snap-fit ​​portion 251 can mate with the groove 2311 to facilitate the adjustment of the adjusting component 24. It can be understood that the snap-fit ​​portion 251 can at least partially snap into the groove 2311.

[0057] For example, such as Figure 7A As shown, the adjusting member 24 is relative to the first housing 23 (e.g. Figure 5 As shown, when moving along the first direction X, the snap-fit ​​part 251 can move from one groove 2311 to another groove 2311. Figure 7A This is a schematic diagram of an adjustment mechanism provided in an embodiment of this application.

[0058] In this embodiment, during the sliding of the first housing 23, the locking part 251 of the adjusting member 24 can move from one groove 2311 to another. The engagement of the locking part 251 with the groove 2311 facilitates control over the length of the wristband 20. As the locking part 251 moves from one groove 2311 to another, the size of the wristband 20 changes, allowing for fine-tuning. The fine-tuning distance is the distance between the two grooves. Furthermore, when the length of the wristband 20 does not need to be adjusted, the locking part 251 engages within one of the grooves 2311. The locking part 251 can be used to limit the position of the adjusting member 24, preventing accidental sliding of the adjusting member 24 within the first housing 23.

[0059] The groove 2311 restricts the movement of the snap-fit ​​portion 251 and restricts the sliding of the adjusting member 24. In some embodiments, such as... Figure 6 As shown, the adjusting member 24 may include a first button 261. By operating the first button 261, the locking part 251 can be moved out of the groove 2311 or into the groove 2311.

[0060] For example, such as Figure 7C As shown, the locking part 251 can be moved out of the groove 2311 by operating the first button 261. For example, pressing the first button 261 will move the locking part 251 out of the groove 2311. After the locking part 251 is moved out of the groove 2311, the groove 2311 no longer restricts the movement of the adjusting member 24. The user can push the adjusting member 24 to adjust the length of the wristband 20 as needed.

[0061] To facilitate button operation by users while wearing the device, in some embodiments, such as Figure 5 , Figure 7B As shown, the first side plate 2321 is provided with a first guide groove 23211, see [reference]. Figure 7B This allows one end of the first button 261 to extend out of the first guide groove 23211. When one end of the first button 261 moves toward or away from the first housing 23, the snap-fit ​​part 251 can move toward or away from the groove 2311.

[0062] Thus, in this application, one end of the first button 261 extends out of the first guide groove 23211, that is, one end of the first button 261 protrudes from the first side plate 2321. When wearing the watch, the first button 261 can be pressed to make the snap-fit ​​part 251 of the snap-fit ​​member 25 move away from the groove 2311. Then, by pushing the adjustment member 24, the length of the watch strap can be finely adjusted, making the operation simpler and improving the user experience.

[0063] In order for the adjusting member 24 to move relative to the first housing 23 in a first direction, such as Figure 5 As shown, the extension direction of the first guide groove 23211 can be parallel to the first direction X. The first button 261 can also be slidably connected to the first guide groove 23211. When the adjusting member 24 moves relative to the first housing 23 along the first direction X, the first button 261 can slide along the first guide groove 23211.

[0064] For example, when it is necessary to move the adjustment member 24, the user can press the first button 261 while pushing the adjustment member 24, so that the locking part 251 of the locking member 25 moves out of the groove 2311, and the adjustment member 24 can reciprocate relative to the first housing 23 along the first direction X. After reaching the required length, the user releases the first button 261, and the button no longer applies an upward force to the locking part 251. The locking part 251 moves downward and locks into one of the grooves 2311. In this way, the watch strap can be fine-tuned while wearing.

[0065] The adjustment mechanism 22 provided in this application embodiment allows the adjustment member 24 to reciprocate relative to the first housing 23 along a first direction. The second connecting strap 212 is rotatably connected to the adjustment member 24 and reciprocates with it. When the adjustment member 24 moves the second connecting strap 212 out of the first housing 23, the overlap between the second connecting strap 212 and the first housing 23 gradually decreases, increasing the overall length of the wristband 20. When the adjustment member 24 moves the second connecting strap 212 into the first housing 23, the overlap between the second connecting strap 212 and the first housing 23 gradually increases, decreasing the overall length of the wristband 20. The sliding range of the adjustment member 24 is the area where the multiple grooves 2311 are located. This allows for fine-tuning of the wristband 20. Furthermore, in this application, one end of the first button 261 extends out of the first guide groove 23211, that is, one end of the first button 261 protrudes from the first side plate 2321, enabling fine-tuning of the watchband while wearing it, simplifying operation and improving user experience.

[0066] In addition, the groove 2311 is provided on the bottom plate 231 of the first housing 23, and the adjusting member 24 is slidably connected to the first side plate 2321 of the first housing 23, so that the sliding connection part and the fine adjustment part are located at different positions of the first housing 23, which is conducive to making full use of the space of the first housing 23 and realizing the miniaturization of the first housing 23.

[0067] This application embodiment does not limit the pressing direction of the first button 261. In some embodiments, the pressing direction of the first button 261 is perpendicular to the first direction X. For example, such as Figure 6As shown, the pressing direction of the first button 261 is the Y-axis, which is perpendicular to the X-axis. This facilitates button operation while wearing the device, making it simple to operate, conforming to user habits, and improving the user experience.

[0068] In some embodiments, there may be an error in the perpendicularity of the pressing direction of the first button 261 to the first direction X. For example, the error angle can be 5°, 15°, or 30°, etc. For example, it is sufficient to ensure that the pressing direction of the first button 261 is not parallel to the first direction X.

[0069] like Figure 7B As shown, the adjusting member 24 also includes a second housing 27, which is slidably connected to the first housing 23. The latch 252 of the snap-fit ​​member 25 is located inside the second housing 27. One end of the first button 261 extends into the second housing 27 and is inserted into the latch 252. The other end of the first button 261 extends out of the first guide groove 23211. When the first button 261 moves relative to the second housing 27, the latch 252 can drive the snap-fit ​​part 251 away from or towards the groove 2311.

[0070] The first button 261 is inserted into the latch 252 at one end and has a first inclined surface 2601. The first inclined surface 2601 is disposed away from the latching part 251 and is disposed at an angle to the first direction X. The first inclined surface 2601 abuts against the latch 252.

[0071] The latch 252 includes a second inclined surface 2501 that is adapted to the shape of the first inclined surface 2601. The first button 261 engages with the second inclined surface 2501 of the latch 252 via the first inclined surface 2601. When the button is operated, a small amount of force is required to move the latch 252 upward so as to move the locking part 251 out of the groove 2311.

[0072] In some embodiments, the adjusting member 24 may further include a first elastic member 241, which may be elastically connected between the side of the latch 252 facing away from the groove 2311 and the second housing 27. The number of first elastic members 241 may be one, two, or three, etc.

[0073] The first elastic element 241 can be a spring or other structural component with elastic deformation capability. When the user operates the button to move the latch 252 away from the groove 2311, the first elastic element 241 is compressed, and the latch 252 is subjected to the elastic force of the first elastic element 241 toward the groove 2311. When the user does not press the button, the elastic force of the first elastic element 241 on the latch 252 causes the latch 252 to move toward the groove 2311. By setting the first elastic element 241, it is beneficial to realize the movement of the latch 252.

[0074] In some embodiments, to improve the stability of the first elastic member 241, the radial dimension of the first elastic member 241 is relatively large, and to support the first elastic member 241, the width of the latch 252 is relatively wide. See also... Figure 8A The width of latch 252 is its dimension along the Y direction. The width of the first button 261 near latch 252 is narrower, see [reference needed]. Figure 8C The width of the first button 261 near the latch 252 is the dimension of the first inclined surface 2601 along the Y direction. When the first inclined surface 2601 of the first button 261 slides relative to the second inclined surface 2501 of the latch 252, it is prone to wobbling.

[0075] To ensure smoother movement of the first inclined surface 2601 of the first button 261 relative to the second inclined surface 2501 of the latch 252, in some embodiments, such as Figure 8A As shown, the snap-fit ​​component 25 also includes: a first baffle 2531 and a second baffle 2532. The first button 261 can slide along the extension direction of the first baffle 2531 and the second baffle 2532 to reduce the shaking of the first button 261 and make the movement of the first inclined surface 2601 of the first button 261 relative to the second inclined surface 2501 of the latch 252 more stable.

[0076] In some embodiments, reference is then made to Figure 5 The first housing 23 further includes a second side plate 2322, and the bottom plate 231 includes a second side edge, which is parallel to the first direction X. The second side plate 2322 is connected to the second side edge of the bottom plate 231. The first side plate 2321 and the second side plate 2322 are fixed to opposite sides of the bottom plate 231. The bottom plate 231, the first side plate 2321, and the second side plate 2322 together enclose the installation space of the first housing 23. In some embodiments, the first housing 23 can be an integrally formed structure with high structural strength and good reliability. In other embodiments, the first housing 23 can also be a split structure, and the bottom plate 231, the first side plate 2321, and the second side plate 2322 can be connected into an integral structure by means of bonding or welding. The first housing 23 has a first end and a second end that are arranged opposite to each other and distributed along the first direction. The adjustment member 24 is installed in the installation space, which helps to reduce the size of the adjustment mechanism 22 and realize the miniaturization of the adjustment mechanism 22.

[0077] The second side plate 2322 is provided, for example, with a second guide groove 23221 (see...). Figure 7B The second guide groove 23221 can extend along the first direction X.

[0078] like Figure 7BAs shown, the adjusting member 24 also includes a second button 262, one end of which extends out of the second guide groove 23221, and the other end of which extends into the second housing 27 and is inserted into the latch 252.

[0079] In some embodiments, such as Figure 8A As shown, the latch 252 includes a first segment 2521, a second segment 2522, and a third segment 2523 that are fixedly connected in sequence. The locking portion 251 is located on the side of the second segment 2522 facing the bottom, and the first elastic member 241 is located, for example, on the side of the second segment 2522 facing away from the bottom plate 231. The locking portion 251 is located on the side of the second segment 2522 facing the bottom plate 231.

[0080] Understandably, the snap-fit ​​part 251 and the first elastic member 241 can be located on the side facing the base plate 231 of any one of the first segment 2521, the second segment 2522, and the third segment 2523, or any two of them, or all three of them, facing the base plate 231. The snap-fit ​​part 251 is larger in size and more stable during movement. The second segment 2522 is provided with a mating space, and the inner wall surrounding the mating space is inclined. The snap-fit ​​part 251, the first segment 2521, the second segment 2522, and the third segment 2523 can be an integrally formed structure with high strength and good reliability, or they can be separate structures and fixedly connected by welding or bonding.

[0081] Specifically, the first button 261 is inserted into the first segment 2521, and the second button 262 is inserted into the third segment 2523. Thus, the combined action of the first and second buttons makes the movement of the locking part smoother and reduces the difficulty of operation.

[0082] In some embodiments, such as Figure 8B As shown, the first housing 23 and the second housing 24 form a first cavity 27. The first cavity 27 includes a first space 271, a second space 272, and a third space 273 connected in sequence. The latch 252 is located in the second space 272. The first button 261 passes through the first space 271 and abuts against the first segment 2521. The second button 262 passes through the third space 273 and abuts against the third segment. Thus, the combination of the button structure and the latch structure makes the structure more compact and the force evenly distributed, which is beneficial for miniaturizing the adjusting component. Figure 8B This is a schematic diagram of the structure of the second housing after assembly in a first housing and an adjusting member provided in an embodiment of this application.

[0083] In some embodiments, to reduce installation difficulty, such as Figure 8C , Figure 7BAs shown, the first button 261 includes: a first connector 2613, a first support portion 2611, and a second support portion 2612. The first support portion 2611 and the second support portion 2612 can be separate structures and are detachably connected via the first connector 2613. Figure 8C This is a schematic diagram of the structure of the first button in an adjustment component provided in an embodiment of this application.

[0084] The first support portion 2611 passes through the first guide groove 23211 and the first space 271, and the second support portion 2612 passes through the first space 271 and the second space 272. The first support portion 2611 and the second support portion 2612 are stacked in the first space 271, and the first support portion 2611 and the second support portion 2612 are detachably connected by the first connector 2613.

[0085] For example, such as Figure 9 As shown, the first support portion 2611 includes a first connecting hole 26110, and the second support portion 2612 includes a second connecting hole 26120. A first connector 2613 passes through the first connecting hole 26110 and the second connecting hole 26120 to connect the first support portion 2611 and the second support portion 2612. This allows the first button 261 to be divided into multiple parts, reducing assembly difficulty.

[0086] The shape of the first support portion 2611 is not limited in this embodiment. In some embodiments, reference is then made to... Figure 8C The first support portion 2611 includes a first sub-part 26111, a second sub-part 26112, and a third sub-part 26113 connected in sequence. The first sub-part 26111 and the third sub-part 26113 have the same width, while the second sub-part 26112 has a wider width than the first sub-part 26111. The second sub-part 26112 is used for sliding connection with the second housing 27. The widths of the first sub-part 26111, the second sub-part 26112, and the third sub-part 26113 are respectively their dimensions along the Y direction. By adjusting the size of the second sub-part 26112, dust and moisture can be better blocked, preventing impurities such as dust and moisture from the external environment from entering the second housing 27 through the gap between the first support portion 2611 and the second housing 27. Simultaneously, gaps are avoided on the surface of the wearable device, improving both aesthetics and practicality. In addition, the increased contact area between the first support 2611 and the second housing 27 makes the movement of the first support 2611 relative to the second housing 27 more stable.

[0087] In other embodiments, the size of the first sub-part 26111 can be adjusted so that the widths of the first sub-part 26111 and the second sub-part 26112 are the same, and the width of the second sub-part 26112 is greater than the width of the third sub-part 26113. This increases the size of the pressing surface of the first button 261, making it easier for the user to operate.

[0088] To allow the first connector 2613 to slide relative to the second housing 27 along with the first button 261. In some embodiments, such as Figure 10 As shown, the second housing 27 includes a third guide groove 2710, and the first connector 2613 passes through the third guide groove 2710, allowing the first connector 2613 to move within the third guide groove 2710. Figure 10 This is a schematic diagram of the connection structure between an adjusting member and a first housing provided in an embodiment of this application.

[0089] When the first button 261 is operated, the first connector 2613 can move within the third guide groove 2710, allowing the first button 261 to move relative to the second housing 27. The third guide groove 2710 limits the movement of the first button 261 within the second housing 27 to a certain range, which helps to prevent the first button 261 from detaching from the second housing 27.

[0090] Accordingly, the second button 262 includes: a second connector 2623, a third support 2621 and a fourth support 2622, wherein the third support 2621 and the fourth support 2622 can be a split structure and can be detachably connected by the second connector 2623.

[0091] The third support portion 2621 passes through the second guide groove 23221 and the third space 273, and the fourth support portion 2622 passes through the third space 273 and the second space 272. The third support portion 2621 and the fourth support portion 2622 are stacked in the third space 273, and the third support portion 2621 and the fourth support portion 2622 are detachably connected by the second connector 2623.

[0092] The shape of the third support 2621 can be referred to the description of the first support 2611 above, and will not be repeated here.

[0093] In some embodiments, such as Figure 9 As shown, the third support portion 2621 includes a third connecting hole 26210, and the fourth support portion 2622 includes a fourth connecting hole 26220. The second connector 2623 passes through the third connecting hole 26210 and the fourth connecting hole 26220. Figure 9 This is a schematic diagram of the disassembly structure of an adjustment component provided in an embodiment of this application.

[0094] In some embodiments, such as Figure 10 As shown, the second housing 27 includes a fourth guide groove 2720, and the second connector 2623 passes through the fourth guide groove 2720 and is movable within the fourth guide groove 2720.

[0095] When the button is operated, the second connector 2623 can move within the fourth guide groove 2720, allowing the second button 262 to move relative to the second housing 27. The fourth guide groove 2720 limits the movement of the second button 262 within the second housing 27 to a certain range, which helps to prevent the second button 262 from detaching from the second housing 27.

[0096] The way the second button 262 works with the card connector 25 can be referred to the description of the first case 261, and will not be repeated here.

[0097] In some embodiments, such as Figure 10 As shown, the adjusting member 24 may further include a first connecting portion 2701 and a second connecting portion 2702. The first connecting portion 2701 and the second connecting portion 2702 are fixed to opposite sides of the second housing 27, and the first connecting portion 2701 and the second connecting portion 2702 protrude from the second housing 27. The first connecting portion 2701 is slidably connected to the first side plate 2321, and the first connecting portion 2701 can be located on the first guide rail 2301. The first guide rail 2301 is connected to the first side plate 2321, and the first connecting portion 2701 can slide within the first guide rail 2301. The second connecting portion 2702 is slidably connected to the second side plate 2322, and the second connecting portion 2702 can be located on the second guide rail (…). Figure 10 (Not shown in the image), the second connecting portion 2702 is slidable within the second guide rail, so that the second housing 27 is slidably connected to the first housing 23. It is understood that the first guide rail 2301 can define the direction of movement of the second housing 27 through the first connecting portion 2701, and the second guide rail can define the direction of movement of the second housing 27 through the second connecting portion 2702.

[0098] The second housing 27, the first connecting part 2701, and the second connecting part 2702 can be integrally formed, resulting in high structural strength and good reliability. Alternatively, they can be separate structures, with the second housing 27, the first connecting part 2701, and the second connecting part 2702 connected as a single unit through bonding or welding.

[0099] The first connecting portion 2701 has a fifth connecting hole 27011, and the second connecting portion 2702 has a sixth connecting hole 27021. The second connecting band 212 can be rotatably connected to the second housing 27 via a pin 291. Exemplarily, the second connecting band 212 can have a through hole through which the pin 291 passes, with one end of the pin 291 connected to the fifth connecting hole 27011 of the first connecting portion 2701 and the other end connected to the sixth connecting hole 27021 of the second connecting portion 2702. The second connecting band 212 can rotate around the pin 291, achieving a rotatable connection between the second connecting band 212 and the adjusting member 24. In other embodiments, the first connecting portion 2701 and the second connecting portion 2702 can also be fixedly connected to the second connecting band 212; this application does not limit this.

[0100] Figure 11 for Figure 5 MM section view. For example... Figure 11 As shown, in some embodiments, the base plate includes a first end 231a and a second end 231b disposed opposite to each other. The groove 2311 includes a first inner wall 23111 and a second inner wall 23112. The first inner wall 23111 is closer to the first end 231a of the base plate 231 than the second inner wall 23112. The engaging portion 251 can slide out of the groove 2311 from either the first inner wall 23111 or the second inner wall 23112. The angle between the first inner wall 23111 and the first direction X is smaller than the angle between the second inner wall 23112 and the first direction X. The angle between the first inner wall 23111 and the first direction X is smaller than the angle between the second inner wall 23112 and the first direction X. This can be understood as the slope of the first inner wall 23111 being gentler than that of the second inner wall 23112. The locking part 251 can easily move out of the groove 2311 along the first inner wall 23111 toward the first end 231a of the base plate 231, while the locking part 251 is not easy to move out of the groove 2311 along the second inner wall 23112 toward the second end 231b of the base plate 231. By setting different levels of ease of movement to different ends, it is beneficial to improve the user experience.

[0101] When the adjusting member 24 slides towards the second end 231b of the base plate 231 to increase the length of the wristband 20, the locking part 251 is difficult to move along the second inner wall 23112 towards the second end 231b of the base plate 231 due to the steep slope of the second inner wall 23112. It is necessary to press the first button 261 and the second button 262. The first button 261 and the second button 262 apply an upward force to the latch 252, and the locking part 251 moves out of the groove 2311. The locking part 251 can then move towards the second end 231b of the base plate 231, and then push the adjusting member 24 towards the second end 231b of the base plate 231.

[0102] When the adjusting member 24 slides toward the first end 231a of the base plate 231 to reduce the length of the wristband 20, the locking part 251 can easily slide along the first inner wall 23111 to slide out of the groove 2311 due to the gentle slope of the first inner wall 23111. The locking part 251 moves toward the first end 231a of the base plate 231. Without pressing the first button 261 and the second button 262, the adjusting member 24 can be pushed to slide toward the first end 231a of the base plate 231 to reduce the length of the wristband 20.

[0103] The adjustment mechanism provided in this application embodiment requires pressing a button to push the adjustment member 24 when increasing the length of the wristband 20, and can push the adjustment member without pressing a button when decreasing the length of the wristband 20. The difficulty of extending the wristband is greater than the difficulty of shortening the wristband, making the wristband less likely to loosen after wearing, avoiding the wristband from falling off due to accidental stretching, and improving stability and safety.

[0104] In other embodiments, the second inner wall 23112 may be closer to the first end 231a of the base plate 231 than the first inner wall 23111. That is, the second connecting strap 212 can be pushed to drive the adjusting member 24 to slide toward the first end 231a of the base plate 231 without pressing the first button 261 and the second button 262, thereby increasing the length of the wristband.

[0105] Figure 12 , Figure 13 , Figure 14 , Figure 15 These are schematic diagrams of the intermediate product structure assembled with the adjustment mechanism. The following are combined with... Figures 12-15 The assembly process of the adjustment mechanism is explained.

[0106] like Figure 12 As shown, when assembling the adjusting component, the first elastic member 241, the snap-fit ​​member 25, the second support part 2612, and the fourth support part 2622 can be placed into the second housing 27 in sequence to form the following configuration: Figure 13 The adjusting element 24 is shown. Next, it can be adjusted as follows: Figure 13 The adjusting member 24 shown slides into the first housing 23 via a slide rail, resulting in the following: Figure 14 The intermediate structural component shown. Then it can be done as follows: Figure 15 As shown, the first support portion 2611 and the third support portion are inserted from both sides of the first housing 23 through the first guide groove 23211 and the second guide groove 23221 and installed into the adjusting member 24. Then, the first connector 2613 is inserted into the third guide groove 2710 and the second connector 2623 is inserted into the fourth guide groove 2720. The first support portion 2611 and the second support portion 2612 are connected by the first connector 2613, and the third support portion from 2621 and the fourth support portion 2622 are connected by the second connector 2623.

[0107] In some embodiments, for ease of wearing the wristband 2020, such as Figure 4 As shown, the wristband 20 may include an opening and closing mechanism 28. When the opening and closing mechanism 28 is open, the length of the wristband increases, making it easier for the user to wear. For example, the opening and closing mechanism 28 may be a butterfly clasp or a folding clasp.

[0108] See Figure 4 The opening and closing mechanism may include an extension 281, a first extension 282, a second extension 283, and a snap 284. The opening and closing mechanism is connected to the first housing 23 of the adjustment mechanism 22 and is used to open or close the wristband 20. The opening and closing mechanism is connected to one end of the first connecting strap 211.

[0109] Figure 16 for Figure 3 AA sectional view. For example... Figure 16 As shown, the first connecting strap 211 is rotatably connected to the extension 281 via a pin 294. The first connecting strap 211 can rotate relative to the extension 281. When the wristband 20 is fastened, the extension 281 can be located at the first end 231a of the bottom plate 231 of the first housing 23 and abut against the first end 231a of the bottom plate 231 of the first housing 23.

[0110] The second extension member 283 includes a first end 283a and a second end 283b opposite to each other. The first extension member 282 is rotatably connected to the first end 283a of the second extension member 283 via a pin 293. The first extension member 282 can rotate relative to the second extension member 283, and since the first extension member 282 is fixedly connected to the extension portion 281, the rotation of the first extension member 282 can drive the extension portion 281 and the first connecting band 211 to rotate.

[0111] The second end 283b of the second extension 283 is rotatably connected to the first housing 23 via a pin 292.

[0112] The first extension 282 includes a first portion 2821 and a second portion 2822 spaced apart, both of which are fixedly connected to the extension 281. The first portion 2821 is provided with a first fastening portion 2823. The snap fastener 284 includes a first snap fastener 2841 and a second snap fastener 2842.

[0113] When the wristband 20 is fastened, the first fastening portion 2823 of the first extension 282 locks with the first snap 2841. For example, the first fastening portion 2823 has a locking hole 2824, and the first snap 2841 has an overlapping member, which is located within the locking hole 2824 of the first fastening portion 2823. The second fastening portion of the first extension 282... Figure 4(Not shown in the image) Locks with the second snap 2842. The first extension 282 is fixed to the first housing 23 by the first snap 2841, and the first extension 282 cannot rotate relative to the second extension 283. The locking of the second snap part of the first extension 282 with the other snap 284 is described in the section on the locking of the first snap part 2823 of the first extension 282 with the snap 284, and will not be repeated here.

[0114] When the wristband 20 is opened, the first snap 2841 and the second snap 2842 are operated, causing them to move closer to each other. The overlapping part of the first snap 2841 moves out of the locking hole 2824 of the first fastening part 2823, and the overlapping part of the second snap 2842 moves out of the locking hole of the second fastening part, thus unlocking the first extension 282 from the first housing 23. The first extension 282 can rotate relative to the second extension 283. Understandably, the first extension 282 can drive the extension part 281 and the first connecting strap 211 to rotate together. The second extension 283 can rotate relative to the first housing 23. The opening and closing mechanism is open, i.e., the wristband 20 is opened. After the wristband 20 is opened, the user can wear the wearable device on their wrist.

[0115] In some embodiments, a second elastic member may be provided between the snap 284 and the inner wall of the first housing 23. The second elastic member can be compressed in the direction of movement of the snap 284. When the two snaps 284 are pressed and moved toward each other, the elastic member can be compressed and the snap 284 is subjected to a spring force opposite to the direction of movement. When the snap 284 does not need to be pressed, the snap 284 can move to a preset position under the action of the spring force.

[0116] The adjustment mechanism provided in this application can be used in conjunction with the aforementioned opening and closing mechanism. When a user needs to wear or remove the wearable device, they can operate the opening and closing mechanism to open the wristband, significantly increasing its length for easier wear. When the user only needs to fine-tune the wristband length, they can operate the adjustment mechanism while wearing the device without opening the wristband, thus improving the user experience.

[0117] It should be noted that the above embodiments are illustrated using the adjustment mechanism applied to the wristband of a wearable device as an example. It is understood that the embodiments of this application are not limited to this. For example, the above adjustment structure can also be applied to the length adjustment of other straps.

[0118] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
