Description

Adjustment mechanisms, wrist straps, and wearable devices

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on May 15, 2023, with application number 202310544389.5 and application name “Adjustment mechanism, wristband and wearable device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention relates to the field of wearable technology, and in particular to an adjustment mechanism, a wristband and a wearable device. Background Art

[0003] Most wearable devices on the market currently adjust the length of the wristband to fit the wearer's wrist size by increasing or decreasing the length of the wristband. Common steel watchbands adjust the length and tightness of the strap by increasing or decreasing the number of beads on the strap.

[0004] However, the wearer's wrist size changes with the environment. For example, the wrist size may increase after exercise. In some scenarios, such as when wearing a diving suit, winter clothes, or sweaters, the wristband of the wearable device needs to be able to adjust the length at any time to maintain a comfortable wrist. Therefore, it is necessary to design an adjustment mechanism that allows the wearer to fine-tune the wristband to accurately adapt to the wearer's wrist size and improve wearing comfort.

[0005] Summary of the Invention

[0006] The embodiment of the present application provides an adjustment mechanism, a wristband, and a wearable device. The adjustment mechanism in the embodiment of the present application can achieve fine adjustment of the wristband length, and the user can adjust the wristband length anytime and anywhere, thereby improving the user's wearing experience.

[0007] In a first aspect, embodiments of the present application provide an adjustment mechanism. The adjustment mechanism is applied to a wristband, which includes a connecting strap. The adjustment mechanism includes a housing and an adjustment member, the adjustment member being configured to connect to one end of the connecting strap. The housing includes a bottom, a first side, and a second side. The bottom extends along a first direction. The first and second side portions are fixed to opposite sides of the bottom and form a mounting space with the bottom. A locking portion is provided on a side of the bottom facing the mounting space. The locking portion includes a plurality of grooves arranged in the first direction. The adjustment member is located in the mounting space and slidably connects the first and second side portions. A locking portion is provided on a side of the adjustment member facing the bottom. When the adjustment member moves relative to the housing in the first direction, the locking portion can move from one groove to the other. The location of the adjustment member in the mounting space of the housing facilitates reducing the size of the adjustment mechanism. The adjustment member can be connected to the connecting strap of the wristband, and the adjustment mechanism is configured to adjust the length of the wristband. The adjustment member is slidably connected to the first and second side portions, facilitating a stable sliding connection of the adjustment member to the housing. Illustratively, both the first side portion and the second side portion may be provided with a slide groove, and a partial structure of the adjusting member is located in the slide groove so as to slide in the slide groove.

[0008] In the embodiment of the present application, the adjusting member is capable of sliding within the housing. The adjusting member is used to connect to the connecting strap of the wristband. When the adjusting member slides, the connecting strap is driven to move, and the connecting strap can be partially moved out of the housing or into the housing to increase or decrease the overall length of the wristband. Specifically, one end of the connecting strap is connected to the adjusting member, which causes a portion of the connecting strap to overlap with the housing. When the adjusting member drives the connecting strap out of the housing, the overlapping portion of the connecting strap and the housing gradually decreases, and the overall length of the wristband increases. When the adjusting member drives the connecting strap into the housing, the overlapping portion of the connecting strap and the housing gradually increases, and the overall length of the wristband decreases.

[0009] The coordination of the snap-fitting portion and the engaging portion facilitates control of the wristband's adjustable length. As the snap-fitting portion moves from one groove to another, the wristband's size changes, facilitating fine-tuning. When the wristband's length does not need to be adjusted, the snap-fitting portion, when engaged in one of the grooves, can be used to define the position of the adjusting member, preventing accidental contact that could cause the adjusting member to slide freely within the housing, thereby improving the user experience. The engaging portion is disposed at the bottom of the housing, and the adjusting member is slidably connected to the first and second side portions of the housing, such that the sliding connection portion and the fine-tuning portion are located at different positions within the housing, making full use of the housing's space and miniaturizing the housing.

[0010] It is understandable that the length of the shell can be set to be smaller. When the length of the shell is longer, the shell occupies a larger proportion of the overall length of the wristband, affecting the aesthetic appearance of the wristband. Moreover, since the shell is generally not bendable, a shell that is too long will affect the user's wearing comfort. In other embodiments, the length of the shell can also be set to be larger. A larger shell length can provide more grooves, increase the range of movement of the adjustment member, and allow the user to fine-tune a larger range of lengths. It is understandable that the size of the shell can be set as needed, and this application does not limit this.

[0011] In one possible embodiment, the housing includes a first end and a second end that are arranged opposite to each other, and the adjusting member is used to increase the length of the wristband when sliding in the direction from the first end to the second end, and is used to reduce the length of the wristband when sliding in the direction from the second end to the first end; the groove includes a first inner wall and a second inner wall, the first inner wall is closer to the first end than the second inner wall, the clamping portion can slide out of the groove from the first inner wall or the second inner wall, the angle between the first inner wall and the second direction is greater than the angle between the second inner wall and the second direction, and the second direction is the thickness direction of the bottom. The angle between the first inner wall and the second direction is greater than the angle between the second inner wall and the second direction, which can be understood as the slope of the first inner wall is gentler than the slope of the second inner wall, the clamping portion is easy to move out of the groove along the first inner wall toward the first end, and the clamping portion is not easy to move out of the groove along the second inner wall toward the second end. By setting different degrees of difficulty in moving to different ends, it is beneficial to improve the user experience. It can be understood that in the embodiment of the present application, the moving range of the adjusting member is the area where the multiple grooves are located. The aforementioned direction from the first end to the second end or the direction from the second end to the first end only indicates the direction, and does not mean that the adjusting member can move to the position of the first end or the second end.

[0012] In other embodiments, the angle between the first inner wall and the second direction may be smaller than or equal to the angle between the second inner wall and the second direction. The embodiment of the present application does not limit the specific structure of the groove.

[0013] In one possible embodiment, the adjusting member includes a sliding portion, a button, and a lock. The sliding portion is slidably connected to the housing. The lock includes the snap-fit ​​portion. The lock is plugged into the sliding portion, and the snap-fit ​​portion is exposed from the sliding portion. One end of the button extends into the sliding portion and is plugged into the lock. The other end of the button is exposed from the sliding portion. When the button moves relative to the sliding portion, the lock moves away from or closer to the snap-fit ​​portion. The snap-fit ​​portion restricts the movement of the snap-fit ​​portion and thus restricts the sliding of the sliding portion. By operating the button, the snap-fit ​​portion of the lock is moved out of the snap-fit ​​portion. The snap-fit ​​portion can be moved from one groove to another, which is conducive to moving the sliding portion as needed to adjust the length of the wristband.

[0014] In one possible embodiment, the button is slidably connected to the sliding portion, and the sliding direction is parallel to the first direction. The direction of button movement is consistent with the sliding direction of the adjusting member. When the button is operated to move the engaging portion out of the engaging portion, the adjusting member can also be driven to move. This simplifies operation, conforms to user operating habits, and improves the user experience.

[0015] In one possible embodiment, one end of the button that is inserted into the lock catch is provided with a bevel, the bevel being disposed away from the engaging portion and at an angle to the second direction, abutting the lock catch, with the second direction being the thickness direction of the bottom portion. It is understood that the inner wall of the lock catch that engages the button is also inclined to mate with the bevel. The button engages the lock catch via the bevel, and when the button is operated, the button is pushed in the sliding direction of the adjusting member, causing the lock catch to slide along the bevel and move away from the groove. When the button is operated, a relatively small amount of force is required to move the engaging portion out of the groove.

[0016] In one possible embodiment, the sliding portion includes a first space and a second space that are interconnected. The lock is located in the first space, and one end of the button inserted into the lock extends out of the lock and into the second space, and the button overlaps the inner wall of the second space. When the size of the inclined surface is large, the end of the button inserted into the lock can extend out of the lock, that is, the inclined surface can extend out of the lock. The contact area between the inclined surface and the lock is large, the fit is more stable, and it avoids the situation when the inclined surface is small, where the inclined surface is stuck with the inner wall of the first space, resulting in the button being unable to be pressed. The button overlapping the inner wall of the second space allows both ends of the button to be supported by the sliding portion, making the button more stable when operating the button.

[0017] In a possible embodiment, the adjusting member further includes a first elastic member, which is elastically connected between the side of the lock buckle facing away from the engaging portion and the sliding portion. The first elastic member can be a structural member with elastic deformation ability, such as a spring. When the user operates the button to drive the lock buckle to move away from the engaging portion, the first elastic member is compressed, and the lock buckle is subjected to an elastic force toward the engaging portion. When the user does not press the button, the elastic force applied to the lock buckle causes the lock buckle to move toward the engaging portion. The provision of the first elastic member facilitates the movement of the lock buckle. The number of first elastic members can be one, two, three, etc., and this application does not limit the number of first elastic members.

[0018] In one possible embodiment, the adjusting member further includes a second elastic member, which is elastically connected between the button and the sliding portion, and the second elastic member can be extended and retracted in the first direction. The second elastic member can be a structural member with elastic deformation ability, such as a spring. When the user operates the button to drive the lock to move, the second elastic member is compressed, and the button is subjected to the elastic force of the second elastic member. The elastic force of the second elastic member is opposite to the movement direction of the button. By providing the second elastic member, the movement of the button is facilitated. The number of second elastic members can be one, two, or three, etc., and this application does not limit the number of second elastic members.

[0019] In one possible embodiment, the button includes an operating portion, a matching portion, a first supporting portion, and a second supporting portion, wherein the first supporting portion, the matching portion, and the second supporting portion are fixed in sequence at intervals on the same side of the operating portion, and the second elastic member is located at the first supporting portion or the second supporting portion; the lock includes a first section, a second section, and a third section fixedly connected in sequence, the clamping portion is located on the side of the first section, the second section, or the third section facing the bottom, and the first elastic member is located at the first section or the third section; the matching portion is plugged into the second section, the first section is located between the first supporting portion and the matching portion, and the third section is located between the matching portion and the second supporting portion. The structure of the button in the embodiment of the present application cooperates with the structure of the lock, making the structure more compact and the force balanced, which is conducive to the miniaturization of the adjustment member.

[0020] In one possible embodiment, the adjusting member further includes a first limit pin, the sliding portion is provided with a limit hole, the first limit pin passes through the connection hole of the button and the limit hole, and the first limit pin is capable of moving within the limit hole. The ability of the first limit pin to move within the first limit hole is beneficial for preventing the button from detaching from the sliding portion and enables the button to move relative to the sliding portion. The first limit hole limits the movement of the button within the sliding portion to a certain range. The number of first limit holes can be two, and the corresponding number of first limit pins can also be two. The two first limit holes can be symmetrically distributed on the sliding portion, which is conducive to the stable movement of the button.

[0021] In one possible embodiment, the adjusting member further includes a second limiting pin, the housing is provided with a limiting groove, the limiting groove extends along the first direction, the second limiting pin passes through the connecting hole of the sliding portion and is located in the limiting groove, and the second limiting pin can move in the limiting groove. The limiting groove is used to limit the sliding of the sliding portion, which helps to prevent the sliding portion from detaching from the housing during the sliding process. The limiting groove can be located at the bottom of the housing, and the number of limiting grooves can be two, and the number of corresponding second limiting pins can also be two. The two limiting grooves can be distributed on opposite sides of the groove. When the number of limiting grooves is two, it is beneficial to the stable limiting of the sliding portion during the sliding process.

[0022] In other embodiments, the number of limiting grooves can also be one, and the grooves can be divided into two rows, the two rows of grooves are arranged at intervals, and the limiting groove is located in the middle of the two adjacent rows of grooves, so that the limiting groove is located in the middle of the bottom, which is conducive to stable limiting of the sliding part during sliding.

[0023] In one possible embodiment, the sliding portion includes a main portion, a first connecting portion, and a second connecting portion. The first connecting portion and the second connecting portion are fixed to opposite sides of the main portion. Part of the button and part of the lock are located within the main portion. The first connecting portion is slidably connected to the first side portion, and the second connecting portion is slidably connected to the second side portion. The first connecting portion and the second connecting portion are used to connect to the connecting strap of the wristband. The first connecting portion is connected to the connecting strap, and the second connecting portion is connected to the connecting strap. The sliding portion can drive the connecting strap to move.

[0024] In a second aspect, the present application provides a wristband comprising a connecting strap and the adjustment mechanism described in any of the preceding embodiments, wherein one end of the connecting strap is connected to an adjustment member of the adjustment mechanism. The connecting strap may be made of a material such as a soft adhesive tape, a metal strap, a leather strap, or a braided strap, and the present application does not limit the material of the connecting strap. The adjustment mechanism is capable of driving the connecting strap to move to adjust the overall length of the wristband to suit the user's wearing needs in different scenarios and enhance the user experience.

[0025] In one possible embodiment, the wristband includes an opening and closing mechanism connected to one end of the connecting strap and to the housing of the adjustment mechanism, and is used to open or close the wristband. The opening and closing mechanism may be a butterfly clasp or other mechanism. The opening and closing mechanism and the adjustment mechanism may share the same housing, which helps reduce costs and improves the wristband's aesthetic appearance and wearing comfort compared to separate housings for the opening and closing mechanism and the adjustment mechanism.

[0026] In a possible embodiment, the opening and closing mechanism includes a connecting member, a first extension member, a second extension member and a snap button, the connecting member is rotatably connected to the connecting band of the wristband, one end of the first extension member is fixedly connected to the connecting member, the other end of the first extension member is rotatably connected to the second extension member, and the second extension member is rotatably connected to the shell.

[0027] In a third aspect, the present application provides a wearable device comprising a watch body and a wristband as described in any of the foregoing embodiments, wherein the wristband is connected to the watch body, and the watch body is used to display time, or to monitor health data, or to monitor exercise data, or to monitor environmental data. The watch body is connected to the wristband to achieve wearability of the device. The watch body can display time, count time, or tell time, etc.; or, the watch body can continuously detect the user's physical condition, such as heart rate, blood pressure, body temperature, and blood oxygen, etc.; or, the watch body can detect the user's motion status, such as the number of steps, acceleration, and angle, etc.; or, the watch body can detect environmental data such as light, temperature, humidity, and radiation.

[0048] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0049] As shown in Figure 1, Figure 1 is a structural diagram of a wearable device 100. The wearable device 100 includes a watch body 10 and a wristband 20, and the wristband 20 is connected to the watch body 10. For example, the wristband 20 and the watch body 10 can be rotatably connected by a pin (not shown in Figure 1), the pin is connected to the watch body 10, the wristband 20 is rotatably connected to the pin, the wristband 20 can rotate relative to the watch body 10, and the wristband 20 and the watch body 10 can be rotated to any angle. In other embodiments, the wristband 20 and the watch body 10 can also be fixedly connected, and this application is not limited to this. The wristband 20 can be bent into a ring structure and worn on the wrist, arm or other parts, or the ring-shaped wristband 20 can be disassembled and removed from the wrist to achieve a wearable function.

[0050] The watch body 10 can be used to display time, monitor health data, monitor exercise data, or monitor environmental data, among other functions. The watch body 10 is used to implement the corresponding functions of the wearable device 100. For example, the wearable device 100 can be a wearable watch that can display time, keep time, or tell time. Physiological sensors can be incorporated into 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 vital signs, the user's physical condition data can be obtained and processed accordingly when necessary. A motion sensor can also be incorporated into the watch body 10 to monitor the user's exercise status, such as step count, acceleration, and angle. By analyzing the user's exercise data, information such as exercise intensity and calorie consumption can be obtained, and a healthier exercise plan can be recommended. Environmental sensors can also be incorporated into the watch body 10 to monitor environmental data such as light, temperature, humidity, and radiation. By analyzing this environmental information, the user's surroundings can be understood and adjusted accordingly, such as recommending light-blocking glasses or increasing warmth, providing the user with a more comfortable living experience.

[0051] This embodiment of the present application uses a wearable watch as an example of a wearable device 100. The wearable watch can be a mechanical watch, an electronic watch, a quartz watch, or the like. The wearable device 100 shown in FIG1 is merely a schematic representation. The watch body 10 can be circular or square, for example, and the size and shape of the wristband 20 can be customized. This embodiment of the present application does not limit the specific structure of the wearable device 100.

[0052] When using the wearable device 100, a dedicated tool is generally required to increase or decrease the length of the wristband 20 to accommodate the wearer's wrist size, depending on the wearer's needs. However, the wearer's wrist size changes with the environment; for example, the wrist size increases after exercise. In some scenarios, such as when wearing a diving suit, winter clothing, or sweater, the wristband 20 of the wearable device 100 needs to be able to be adjusted in length at any time to maintain a comfortable wrist. The present embodiment provides an adjustment mechanism that can fine-tune the size of the wristband 20 anytime and anywhere, accurately adapting it to the wearer's wrist size and improving wearing comfort.

[0053] As shown in Figures 1, 2 and 3, Figure 2 is a structural schematic diagram of the wristband 20 shown in Figure 1, and Figure 3 is a structural schematic diagram of the wristband 20 shown in Figure 2 from another angle. Figure 2 is a perspective of the wristband 20 facing away from the wrist, and Figure 3 is a perspective of the wristband 20 facing the wrist.

[0054] The wristband 20 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 parts 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 with each other. A watch body 10 may also be provided between the first connecting strap 211 and the second connecting strap 212. The embodiment of the present application is described by taking the watch body 10 provided between the first connecting strap 211 and the second connecting strap 212 as an example. One end of the first connecting strap 211 may be connected to the adjustment mechanism 22, and the other end of the first connecting strap 211 may be connected to the watch body 10. One end of the second connecting strap 212 may be connected to the adjustment mechanism 22, and the other end of the second connecting strap 212 may be connected to the watch body 10. The connection method between the first connecting strap 211 and the second connecting strap 212 and the watch body 10 and the adjustment mechanism 22 may be a rotating connection or a fixed connection, etc., which is not limited in the present application.

[0055] It is understandable that the first connecting belt 211 and the second connecting belt 212 can be made of materials such as soft tape, metal tape, belt or braided tape. This application does not limit the material of the first connecting belt 211 and the second connecting belt 212.

[0056] As shown in Figures 4, 5 and 6, Figure 4 is a schematic diagram of the exploded structure of the wristband 20 shown in Figure 3, Figure 5 is a schematic diagram of the structure of the adjustment mechanism 22 of the wristband shown in Figure 4, and Figure 6 is a schematic diagram of the structure of the shell 23 of the adjustment mechanism shown in Figure 5.

[0057] The adjustment mechanism 22 is applied to the wristband 20. The adjustment mechanism 22 can drive the first connecting strap 211 or the second connecting strap 212 to move (the embodiment of the present application is introduced as an example using the adjustment mechanism 22 being able to drive the second connecting strap 212 to move) to adjust the overall length of the wristband 20 to adapt to the user's wearing needs in different scenarios and improve the user's experience.

[0058] The adjustment mechanism 22 may include a housing 23 and an adjustment member 24. The housing 23 may be connected to one end of the first connecting belt 211, and the adjustment member 24 may be connected to one end of the second connecting belt 212. The adjustment member 24 is slidably connected to the housing 23 and is capable of sliding within the housing 23.

[0059] The housing 23 may include a bottom 231, a first side 232, and a second side 233. The bottom 231 extends along a first direction A1. The first and second side 232, 233 are fixed to opposite sides of the bottom 231. The bottom 231, the first and second side 232, 233 together enclose a mounting space 230 for the housing 23. The housing 23 may be a one-piece structure, which provides high structural strength and reliability. Alternatively, the housing 23 may be a split structure, with the bottom 231, the first and second side 232, 233 connected to form a one-piece structure by bonding or welding. The housing 23 has a first end 234 and a second end 235, which are oppositely disposed and extend along the first direction A1.

[0060] A locking portion 2311 may be provided on a side of the bottom 231 facing the installation space 230. The locking portion 2311 may include multiple grooves 2312, with the number of grooves 2312 being at least two. For example, the number of grooves 2312 may be two, three, four, or five, etc., and this application does not limit the number of grooves 2312. The multiple grooves 2312 may be arranged sequentially along the first direction A1.

[0061] The first side portion 232 is provided with a first sliding groove 2321, and the second side portion 233 is provided with a second sliding groove 2331. The first sliding groove 2321 can extend along the first direction A1, and the second sliding groove 2331 can extend along the first direction A1.

[0062] As shown in Figures 5, 6 and 7, Figure 7 is a schematic structural diagram of the adjusting member 24 of the adjusting mechanism shown in Figure 5. A clamping portion 271 is provided on the side of the adjusting member 24 facing the bottom 231, and the clamping portion 271 is a raised structure. The adjusting member 24 is installed in the installation space 230 of the shell 23 and is slidably connected to the shell 23. Exemplarily, one side of the adjusting member 24 is located in the first slide groove 2321, and the other side of the adjusting member 24 is located in the second slide groove 2331, so as to realize the sliding connection between the adjusting member 24 and the first side portion 232 and the sliding connection between the adjusting member 24 and the second side portion 233, which is conducive to the stable sliding of the adjusting member 24 in the shell 23. The installation of the adjusting member 24 in the installation space 230 is conducive to reducing the size of the adjusting mechanism 22 and realizing the miniaturization of the adjusting mechanism 22.

[0063] The engaging portion 271 can cooperate with the engaging portion 2311 to coordinate with the adjustment of the adjusting member 24. It is understood that at least a portion of the engaging portion 271 can be engaged with the groove 2312. When the adjusting member 24 moves relative to the housing 23 in the first direction A1, the engaging portion 271 can move from one groove 2312 to the other groove 2312.

[0064] In some embodiments, the adjusting member 24 may include a button 26 , and the button 26 may cooperate with the clamping portion 271 to move the clamping portion 271 out of the groove 2312 or into the groove 2312 .

[0065] In the embodiment of the present application, the adjusting member 24 can slide within the housing 23 and can reciprocate along the first direction A1. The second connecting band 212 can be rotatably connected to the adjusting member 24, and a portion of the second connecting band 212 will overlap with the housing 23, that is, a portion of the second connecting band 212 is located within the installation space 230 of the housing 23. When the adjusting member 24 drives the second connecting band 212 to move out of the housing 23 (i.e., the adjusting member 24 slides from the first end 234 to the second end 235), the overlapping portion of the second connecting band 212 and the housing 23 gradually decreases, and the overall length of the wristband 20 increases; when the adjusting member 24 drives the second connecting band 212 to move into the housing 23 (i.e., the adjusting member 24 slides from the second end 235 to the first end 234), the overlapping portion of the second connecting band 212 and the housing 23 gradually increases, and the overall length of the wristband 20 decreases. It can be understood that the sliding range of the adjusting member 24 is the area where the multiple grooves 2312 are located.

[0066] In the embodiment of the present application, as the adjusting member 24 slides within the housing 23, the engaging portion 271 can move from one groove 2312 to another. The cooperation between the engaging portion 271 and the engaging portion 2311 facilitates controlling the adjustable length of the wristband 20. As the engaging portion 271 moves from one groove 2312 to another, the size of the wristband 20 changes, enabling fine-tuning. The size of the fine-tuning is the distance between one groove 2312 and another groove 2312. Furthermore, when the length of the wristband 20 does not need to be adjusted, the engaging portion 271 engages within one of the grooves 2312. The engaging portion 271 can be used to limit the position of the adjusting member 24, preventing accidental contact that could cause the adjusting member 24 to slide freely within the housing 23. The locking portion 2311 is set at the bottom 231 of the shell 23, and the adjusting member 24 is slidingly connected to the first side portion 232 and the second side portion 233 of the shell 23, so that the sliding connection part and the fine-tuning part are respectively located at different positions of the shell 23, which is conducive to making full use of the space of the shell 23 and realizing the miniaturization of the shell 23.

[0067] As shown in Figures 5 and 8, Figure 8 is a schematic diagram of the exploded structure of the adjustment member 24 shown in Figure 7. The adjustment member 24 may include a sliding portion 25, a button 26, and a lock 27. The sliding portion 25 is configured to be slidably connected to the housing 23, the button 26 is configured for user operation to slide the sliding portion 25, and the lock 27 is configured to engage with the groove 2312 of the housing 23 to achieve fine-tuning of the size of the wristband 20.

[0068] The sliding portion 25 may include a main portion 251, a first connecting portion 252, and a second connecting portion 253. The first connecting portion 252 and the second connecting portion 253 are fixed to opposite sides of the main portion 251, and the first connecting portion 252 and the second connecting portion 253 protrude from the main portion 251. The first connecting portion 252 is slidably connected to the first side portion 232 and may be located in a first sliding groove 2321, within which the first connecting portion 252 can slide. The second connecting portion 253 is slidably connected to the second side portion 233 and may be located in a second sliding groove 2331, within which the second connecting portion 253 can slide, thereby slidably connecting the sliding portion 25 to the housing 23. It will be appreciated that the first sliding groove 2321 can define the movement direction of the sliding portion 25 via the first connecting portion 252, and the second sliding groove 2331 can define the movement direction of the sliding portion 25 via the second connecting portion 253.

[0069] The sliding portion 25 can be an integrally formed structure with high structural strength and good reliability. The sliding portion 25 can also be a split structure in which the main portion 251, the first connecting portion 252 and the second connecting portion 253 are connected into an integral structure by bonding or welding.

[0070] Referring to Figures 4 and 8, the first connecting portion 252 is provided with a first connecting hole 2521, and the second connecting portion 253 is provided with a second connecting hole 2531. The second connecting band 212 can be rotatably connected to the sliding portion 25 via a first pin 2121. For example, the second connecting band 212 can be provided with a through hole 2122, through which a first pin 2121 passes, with one end of the first pin 2121 connected to the first connecting hole 2521 of the first connecting portion 252, and the other end of the first pin 2121 connected to the second connecting hole 2531 of the second connecting portion 253. The second connecting band 212 can rotate around the first pin 2121, thereby achieving a rotational connection between the second connecting band 212 and the adjusting member 24. In other embodiments, the first connecting portion 252 and the second connecting portion 253 can also be fixedly connected to the second connecting band 212, which is not limited in this application.

[0071] Referring to Figure 8 , the button 26 may include an operating portion 261, a mating portion 262, a first support portion 263, and a second support portion 264. The operating portion 261 is used by the user to control the button 26. The mating portion 262, the first support portion 263, and the second support portion 264 are spaced apart and arranged on the same side of the operating portion 261. The first support portion 263 and the second support portion 264 are located on opposite sides of the mating portion 262. The mating portion 262 is located at the end of the button 26 that engages the lock 27. A sloped surface 2621 is provided on the side of the mating portion 262 facing away from the operating portion 261.

[0072] It can be understood that the operating portion 261, the matching portion 262, the first support portion 263 and the second support portion 264 can be an integrally formed structure with high strength and good reliability, or they can be a split structure and fixedly connected by welding or bonding.

[0073] Referring to Figure 9, Figure 9 is a schematic structural diagram of the adjusting member 24 shown in Figure 8 from another angle. In some embodiments, a surface 2611 of the operating portion 261 away from the sliding portion 25 is provided with a first groove 2612. The number of the first grooves 2612 can be two, and the two first grooves 2612 are spaced apart. The provision of the first grooves 2612 can enhance the user's operating feel.

[0074] It is understandable that in some embodiments, the button 26 may not be provided with the first support portion 263 or the second support portion 264 , and the present application does not limit the specific structure of the button 26 .

[0075] Referring to Figures 8 and 9, the lock 27 may include a snap-fit ​​portion 271 and a first section 274, a second section 275, and a third section 276, which are fixedly connected in sequence. The snap-fit ​​portion 271 is located on the side of the first section 274, the second section 275, or the third section 276 facing the bottom 231. It is understood that the snap-fit ​​portion 271 can be located on the side of any one of the first section 274, the second section 275, or the third section 276 facing the bottom 231, or on the side of any two of the first section 274, the second section 275, or the third section 276 facing the bottom 231, or on the side of all three facing the bottom 231. The snap-fit ​​portion 271 is larger, providing greater stability during movement. The second section 275 defines a mating space 273, and the inner wall 2731 surrounding the mating space 273 is inclined. The snap-fit ​​portion 271, the first section 274, the second section 275, and the third section 276 can be integrally formed for high strength and reliability, or they can be separate structures fixedly connected by welding or adhesive bonding.

[0076] Referring to Figures 8, 9, 10 and 11, Figure 10 is a structural schematic diagram of another state of the adjustment member 24 shown in Figure 9, the button 26 and the lock 27 in Figure 10 are combined together, and Figure 11 is a partial structural schematic diagram of the cross-sectional view of the wristband 20 along LL shown in Figure 3. The structure at H1 and the structure at H2 are enlarged in Figure 11. In order to see the structure of the wristband 20 more clearly, the section line is not shown in Figure 11.

[0077] In some embodiments, the sliding portion 25 may be provided with a receiving space 2511 and an opening 2513. The receiving space 2511 is a hollow space, and the opening 2513 is located at the bottom of the main portion 251.

[0078] The lock catch 27 is inserted into the sliding portion 25. The main portion of the lock catch 27 (i.e., the first section 274, the second section 275, and the third section 276) is located in the accommodating space 2511. The engaging portion 271 of the lock catch 27 passes through the opening 2513 to expose the sliding portion 25. The operating portion 261 of the button 26 is exposed from the sliding portion 25, while the engaging portion 262, the first supporting portion 263, and the second supporting portion 264 extend into the accommodating space 2511 of the sliding portion 25.

[0079] The mating portion 262 of the button 26 can extend into the mating space 273 of the lock catch 27, inserting the lock catch 27. The first section 274 is located between the first support portion 263 and the mating portion 262, and the third section 276 is located between the mating portion 262 and the second support portion 264. The structure of the button 26 is coordinated with the structure of the lock catch 27, which facilitates a more compact structure, balanced force distribution, and miniaturization of the adjustment member 24.

[0080] It can be understood that the size of the mating space 273 in the second direction A2 (the second direction A2 is the thickness direction of the bottom 231) is larger than the size of the mating part 262 in the second direction A2, which is conducive to the movement of the lock 27 in the second direction A2 and avoids the bottom of the mating part 262 restricting the movement of the lock 27 when the size of the mating space 273 in the second direction A2 is smaller.

[0081] The inclined surface 2621 of the mating portion 262 is disposed away from the engaging portion 271 and is disposed at an angle with respect to the second direction A2. The inclined surface 2621 of the mating portion 262 can abut against the inner wall 2731 of the lock catch 27. As will be understood, the button 26 engages with the inner wall 2731 of the lock catch 27 via the inclined surface 2621. When the button 26 is operated with minimal force, the lock catch 27 can be moved upward, thereby driving the engaging portion 271 out of the groove 2312. With the inclined surface 2621 abutting against the inner wall 2731 of the lock catch 27, when the button 26 moves relative to the sliding portion 25 in the first direction A1, the lock catch 27 moves away from or closer to the groove 2312. The clamping portion 271 of the lock 27 is located in the groove 2312, which will limit the sliding of the adjusting member 24. During the adjustment process, the button 26 can be pushed toward the second end 235, and the lock 27 slides along the inclined surface and moves away from the groove 2312. The clamping portion 271 moves out of the groove 2312, and the adjusting member 24 can slide toward the second end 235.

[0082] Referring to Figures 9, 10, and 11, in some embodiments, the inclined surface 2621 can extend from the side of the lock catch 27 away from the operating portion 261. The accommodating space 2511 of the sliding portion 25 includes a first space 2511-1 and a second space 2511-2 that are interconnected. The lock catch 27 is located in the first space 2511-1. The end of the button 26 that is inserted into the lock catch 27 extends out of the lock catch 27 and into the second space 2511-2. The mating portion 262 of the button 26 overlaps the inner wall 254 of the second space 2511-2. When the inclined surface 2621 is larger, the inclined surface 2621 can extend from the side of the lock catch 27 away from the operating portion 261. This increases the contact area between the inclined surface 2621 and the lock catch 27, making the mating more stable and preventing the inclined surface 2621 from getting stuck on the inner wall of the first space 2511-1, which could render the button 26 unpressible. It can be understood that the end where the inclined surface 2621 is located extends out of the lock buckle 27 away from the side of the operating part 261 and can be connected to the inner wall 254 of the second space 2511-2, so that both ends of the button 26 are supported by the sliding part 25, and the button 26 is more stable during operation.

[0083] The button 26 can drive the lock 27 to move away from the groove 2312, so that the engaging portion 271 moves out of the groove 2312. The button 26 is slidably connected to the sliding portion 25, and the sliding direction is parallel to the first direction A1. The direction of movement of the button 26 is consistent with the sliding direction of the adjusting member 24. When operating the button 26 to move the engaging portion 271 out of the groove 2312, the adjusting member 24 can also be pushed to move. This operation is simple, conforms to the user's operating habits, and is conducive to improving the user experience. The groove 2312 will limit the movement of the lock 27, thereby limiting the sliding of the sliding portion 25. By operating the button 26 to move the engaging portion 271 of the lock 27 out of the groove 2312, it is convenient to move the sliding portion 25 as needed to adjust the length of the wristband 20. For example, when the sliding portion 25 needs to be moved, the user can operate the operating portion 261 of the button 26. The operating portion 261 acts on the lock 27, and the inclined surface 2621 of the matching portion 262 cooperates with the inner wall 2731 of the lock 27, causing the engaging portion 271 of the lock 27 to move upward and out of the groove 2312. After adjusting to the desired length, the user releases the button 26, and the button 26 no longer applies upward force to the lock 27, causing the lock 27 to move downward, and the engaging portion 271 to engage in one of the grooves 2312.

[0084] 11 , in some embodiments, the groove 2312 includes a first inner wall 2313 and a second inner wall 2314. The first inner wall 2313 is closer to the first end 234 than the second inner wall 2314, and the engaging portion 271 can slide out of the groove 2312 via the first inner wall 2313 or the second inner wall 2314. An angle V1 formed between the first inner wall 2313 and the second direction A2 is greater than an angle V2 formed between the second inner wall 2314 and the second direction A2. The angle V1 between the first inner wall 2313 and the second direction A2 is greater than the angle V1 between the second inner wall 2314 and the second direction A2. It can be understood that the slope of the first inner wall 2313 is gentler than the slope of the second inner wall 2314. The clamping portion 271 can easily move out of the groove 2312 along the first inner wall 2313 toward the first end 234, and the clamping portion 271 is not easy to move out of the groove 2312 along the second inner wall 2314 toward the second end 235. By setting different degrees of difficulty in moving to different ends, it is beneficial to improve the user experience.

[0085] When the adjusting member 24 slides toward the second end 235 to increase the length of the wristband 20, the engaging portion 271 has difficulty moving along the second inner wall 2314 toward the second end 235 due to the steep slope of the second inner wall 2314. Therefore, the operating portion 261 of the button 26 must be pressed in the sliding direction. The button 26 applies an upward force to the lock 27, causing the engaging portion 271 to move out of the groove 2312 and move toward the second end 235, thereby allowing the adjusting member 24 to move toward the second end 235. When the adjusting member 24 slides toward the first end 234 to decrease the length of the wristband 20, the engaging portion 271 easily slides along the first inner wall 2313 and out of the groove 2312 due to the gentle slope of the first inner wall 2313. The engaging portion 271 moves toward the first end 234 without pressing the button 26. The second connecting strap 212 can be pushed to drive the adjusting member 24 to slide toward the first end 234.

[0086] In other embodiments, the angle V1 between the first inner wall 2313 and the second direction A2 may be smaller than or equal to the angle V2 between the second inner wall 2314 and the second direction A2. The embodiment of the present application does not limit the specific structure of the groove 2312.

[0087] Referring to Figure 11 , the length of the housing 23 can be set to be relatively short. For example, the length of the housing 23 can be less than the length of the second extension member 283 of the opening and closing mechanism 28 (the specific structure of the opening and closing mechanism 28 will be described in detail later). If the housing 23 is longer, it occupies a larger proportion of the overall length of the wristband 20, affecting the aesthetic appearance of the wristband 20. Furthermore, since the housing 23 is not bendable, an excessively long housing 23 can affect the user's wearing comfort.

[0088] In other embodiments, the housing 23 may be longer. For example, the length of the housing 23 may be equal to the length of the second extension member 283 of the opening and closing mechanism 28. A longer housing 23 allows for more grooves 2312, increasing the range of movement of the adjustment member 24 and allowing the user to fine-tune the length over a wider range. It is understood that the size of the housing 23 can be adjusted as needed and is not limited in this application.

[0089] As shown in Figures 9, 10, and 11, the adjustment member 24 may further include a first elastic member 241, which may be elastically connected between the side of the lock catch 27 facing away from the groove 2312 and the sliding portion 25. The number of first elastic members 241 may be one, two, or three, and this application does not limit the number of first elastic members 241. For example, if there are two first elastic members 241, one first elastic member 241 is fixed to the first section 274 of the lock catch 27, and the other first elastic member 241 is located in the third section 276 of the lock catch 27.

[0090] The first elastic member 241 can be a spring or other elastically deformable structural member. When the user operates the button 26 to move the lock catch 27 away from the groove 2312, the first elastic member 241 is compressed, and the lock catch 27 is subjected to the elastic force of the first elastic member 241 toward the groove 2312. When the user does not press the button 26, the elastic force of the first elastic member 241 on the lock catch 27 causes the lock catch 27 to move toward the groove 2312. The provision of the first elastic member 241 facilitates the movement of the lock catch 27.

[0091] The adjusting member 24 may further include a second elastic member 242, which may be elastically connected between the button 26 and the sliding portion 25. The second elastic member 242 is capable of extending and contracting in the direction of movement of the button 26. The number of second elastic members 242 may be one, two, or three, and this application does not limit the number of second elastic members 242. For example, in the case of two second elastic members 242, one second elastic member 242 is fixed to the first support portion 263 of the button 26, and the other second elastic member 242 is fixed to the second support portion 264 of the button 26.

[0092] The second elastic member 242 can be a spring or other elastically deformable structural member. When the user operates the button 26 to move the lock catch 27, the second elastic member 242 is compressed, and the button 26 is subjected to the elastic force of the second elastic member 242. The elastic force of the second elastic member 242 is opposite to the direction of movement of the button 26. The provision of the second elastic member 242 facilitates the movement of the button 26.

[0093] 7 , 8 , and 9 , the sliding portion 25 may be provided with a limiting hole 2512 located at the bottom of the main portion 251 . The limiting hole 2512 may be two in number. The adjusting member 24 may also include a first limiting pin 243 , which is exposed at the bottom of the key 26 . The first limiting pin 243 passes through the connection hole 265 (referred to herein as the third connection hole 265 to distinguish it from the first connection hole 2521 and the second connection hole 2531 ) of the key 26 and the limiting hole 2512 of the sliding portion 25 . When the key 26 is operated, the first limiting pin 243 is able to move within the limiting hole 2512 . For example, there may be two first limiting pins 243 , one of which may be located at the first support portion 263 of the key 26 , and the other of which may be located at the second support portion 264 of the key 26 . The first limiting pin 243 can move in the first limiting hole 2512 so that the button 26 can move relative to the sliding part 25, and the first limiting hole 2512 limits the movement of the button 26 in the sliding part 25 to a certain range, which helps to prevent the button 26 from detaching from the sliding part 25.

[0094] Referring to Figures 6, 9, and 12, Figure 12 is a schematic diagram of the three-dimensional structure of the wristband 20 shown in Figure 3 after a portion is cut away along the FF section. Figure 12 enlarges the structure at H3. For a clearer schematic structure, the section lines are not shown in Figure 12. The sliding portion 25 may be provided with a connection hole 2514 (referred to herein as the fourth connection hole 2514 to distinguish it from the first connection hole 2521, the second connection hole 2531, and the third connection hole 265). The fourth connection hole 2514 may pass through the top and bottom of the main portion 251. There may be two fourth connection holes 2514, one of which may be provided near the first connection portion 252, and the other fourth connection hole 2514 may be provided near the second connection portion 253. The adjusting member 24 may also include a second limiting pin 244. The housing 23 is provided with a limiting slot 236, which extends along the first direction A1. The second limiting pin 244 passes through the fourth connection hole 2514 of the sliding portion 25 and is located within the limiting slot 236. The second limiting pin 244 is movable within the limiting slot 236. The limiting slot 236 is used to limit the sliding movement of the sliding portion 25, thereby preventing the sliding portion 25 from separating from the housing 23 during the sliding process. The limiting slots 236 can be located on the bottom 231 of the housing 23. There can be two limiting slots 236, and the corresponding number of second limiting pins 244 can also be two. The two limiting slots 236 can be located on opposite sides of the groove 2312. The presence of two limiting slots 236 facilitates stable positioning of the sliding portion 25 during the sliding process.

[0095] In other embodiments, the number of the limiting groove 236 can also be one, and the grooves 2312 can be divided into two columns, and the two columns of grooves 2312 are arranged at intervals. The limiting groove 236 is located in the middle of the two adjacent columns of grooves 2312, so that the limiting groove 236 is located in the middle of the bottom 231, which is conducive to stable limiting of the sliding part 25 during the sliding process.

[0096] 3 , 13 , 14 and 15 , FIG13 is a schematic diagram of an exploded structure of the wristband 20 shown in FIG3 , FIG14 is a schematic diagram of another exploded structure of the wristband 20 shown in FIG3 , and FIG15 is a schematic diagram of the structure of the wristband 20 shown in FIG14 from another perspective.

[0097] The wristband 20 may include an opening and closing mechanism 28, which may include a connecting member 281, a first extension member 282, a second extension member 283, and a snap 284. The opening and closing mechanism 28 is connected to the housing 23 of the adjustment mechanism 22 and is used to open or close the wristband 20. The opening and closing mechanism 28 is connected to one end of the connecting strap 21. For example, the opening and closing mechanism 28 is connected to one end of the first connecting strap 211.

[0098] The connector 281 has an installation space, and the first connecting band 211 is located in the installation space of the connector 281 and is rotatably connected to the connector 281 via a second pin 285. The first connecting band 211 can rotate relative to the connector 281. When the wristband 20 is fastened, the connector 281 can be located at the first end 234 of the housing 23 and abut against the first end 234 of the housing 23.

[0099] The first extension member 282 includes a first portion 2821, a second portion 2822, and a third portion 2823. The first portion 2821 is fixedly connected to the connector 281, and the second portion 2822 and the third portion 2823 are spaced apart and both are fixedly connected to the first portion 2821. The first portion 2821 and the connector 281 can be connected by welding, snapping, or bonding. The first portion 2821 and the connector 281 can also be integrally formed, which provides high structural strength and reliability. The length of the first portion 2821 can be relatively long so as to overlap with a portion of the first connecting band 211. When the first connecting band 211 is made of a flexible material such as a belt, the connection between the first connecting band 211 and the connector 281 is prone to bending and forming creases. By providing a relatively long first portion 2821 so as to overlap with a portion of the first connecting band 211, strength support is provided to the first connecting band 211, preventing creases from forming at the connection between the first connecting band 211 and the connector 281.

[0100] The second portion 2822 is provided with a first snap-fit ​​portion 2824 and a first hole 2825. The first snap-fit ​​portion 2824 is located at the end of the second portion 2822 closer to the first portion 2821, and the first hole 2825 is located at the end of the second portion 2822 farther from the first portion 2821. The third portion 2823 is provided with a second snap-fit ​​portion 2826 and a second hole 2827. The second snap-fit ​​portion 2826 is located at the end of the third portion 2823 closer to the first portion 2821, and the second hole 2827 is located at the end of the third portion 2823 farther from the first portion 2821.

[0101] The second extension piece 283 includes a fifth portion 2831 and a sixth portion 2832 that are fixedly connected. The fifth portion 2831 is provided with a third hole 2833 , and the sixth portion 2832 is provided with a fourth hole 2834 at one end away from the fifth portion 2831 .

[0102] The first extension member 282 is rotatably connected to the second extension member 283. For example, the sixth portion 2832 of the second extension member 283 is located between the second portion 2822 and the third portion 2823 of the first extension member 282. The fifth portion 2831 of the second extension member 283 is located on the side of the first extension member 282 facing the bottom 231 of the housing 23. The third pin 286 passes through the first hole 2825, the fourth hole 2834, and the second hole 2827, thereby achieving a rotatable connection between the first extension member 282 and the second extension member 283. The first extension member 282 can rotate relative to the second extension member 283 about the third pin 286. Since the first extension member 282 is fixedly connected to the connecting member 281, the rotation of the first extension member 282 can drive the connecting member 281 and the first connecting belt 211 to rotate.

[0103] The second extension member 283 is rotatably connected to the housing 23. For example, the housing 23 is provided with two rotation holes 238, one located on the first side portion 232 and the other located on the second side portion 233. As will be appreciated, the rotation hole 238 on the first side portion 232 is obscured from view in FIG13 . A fourth pin 287 passes through the rotation hole 238 on the first side portion 232, the third hole 2833, and the rotation hole 238 on the second side portion 233, thereby rotatably connecting the second extension member 283 to the housing 23.

[0104] The snap button 284 includes a fixedly connected mounting portion 2841 and a locking portion 2842. The mounting portion 2841 is located in the receiving space 237 of the housing 23, and the locking portion 2842 at least partially extends out of the receiving space 237. There can be two snap buttons 284, and the corresponding receiving spaces 237 can also be two, one receiving space 237 located in the first side portion 232 of the housing 23, and the other receiving space 237 located in the second side portion 233 of the housing 23.

[0105] When the wristband 20 is fastened, the first fastening portion 2824 of the first extension 282 is locked with the locking portion 2842 of the snap 284 (the first fastening portion 2824 has a locking hole 2828, and the locking portion 2842 has a bridging member 2843, and the bridging member 2843 of the locking portion 2842 is located within the locking hole 2828 of the first fastening portion 2824). The first extension 282 is fixed to the housing 23 via the snap 284, and the first extension 282 cannot rotate relative to the second extension 283. The locking of the second fastening portion 2826 of the first extension 282 with the other snap 284 is similar to the locking of the first fastening portion 2824 of the first extension 282 with the snap 284, and will not be repeated here.

[0106] When the wristband 20 is opened, the snap buttons 284 are operated to move the two snap buttons 284 toward each other. The connecting piece 2843 of the locking portion 2842 moves out of the lock hole 2828 of the first locking portion 2824, and the connecting piece 2843 of the other locking portion 2842 moves out of the lock of the second locking portion 2826, thereby unlocking the first extension piece 282 from the housing 23. The first extension piece 282 can rotate relative to the second extension piece 283. It can be understood that the first extension piece 282 can drive the connecting piece 281 and the first connecting band 211 to rotate together. The second extension piece 283 can rotate relative to the housing 23. The opening and closing mechanism 28 is opened, that is, the wristband 20 is opened. After the wristband 20 is opened, the user can put the wearable device on the wrist, or can fine-tune the adjustment mechanism 22 to the appropriate size and then wear it.

[0107] In some embodiments, an elastic member can be arranged between the mounting portion 2841 of the snap 284 and the inner wall of the accommodating space 237 of the shell 23. The elastic member can be compressed in the direction of movement of the snap 284. When the two snaps 284 are pressed so that the two snaps 284 move toward each other, the elastic member can be compressed, and the snaps 284 are subjected to an elastic force opposite to the direction of movement. When there is no need to press the snaps 284, the snaps 284 can move to a preset position under the action of the elastic force.

[0108] The opening and closing mechanism 28 in the embodiment of the present application may be a butterfly buckle structure. In other implementations, the opening and closing mechanism 28 may also be other opening and closing methods. The present application does not limit the specific structure of the opening and closing mechanism 28.

[0109] It can be understood that in the embodiment of the present application, the opening and closing mechanism 28 can share the shell 23 of the adjusting mechanism 22 with the adjusting mechanism 22, which is conducive to reducing costs. Compared with setting up shells for the opening and closing mechanism 28 and the adjusting mechanism 22 separately, it can improve the appearance and wearing comfort of the wristband.

[0110] As shown in Figure 16, Figure 16 is a schematic diagram of the structure of another wristband 20 shown in Figure 1. The difference between the opening and closing mechanism of the wristband 20 shown in Figure 16 and the opening and closing mechanism shown in Figure 13 is that the length of the first portion 2821 of the first extension member 282 of the opening and closing mechanism 28 shown in Figure 16 can be smaller, and the first portion 2821 does not overlap with the first connecting band 211. When the first connecting band 211 is made of a hard material such as metal, the connection between the first connecting band 211 and the connecting member 281 will not bend or crease, and the length of the first portion 2821 can be set to be smaller. For other structures of the opening and closing mechanism of the wristband 20 shown in Figure 16, please refer to the structure of the opening and closing mechanism shown in Figure 13, and will not be repeated here.

[0111] As shown in Figure 17, Figure 17 is a schematic structural diagram of the adjustment member 24 of the wristband 20 shown in Figure 16. The difference between the adjustment member 24 shown in Figure 17 and the adjustment member 24 shown in Figure 9 is that the surface 2611 of the operating portion 261 of the button 26 of the adjustment member 24 shown in Figure 17 away from the sliding portion 25 is smooth, and the top surface 2613 of the operating portion 261 of the button 26 of the adjustment member 24 shown in Figure 17 is provided with a second groove 2614 and an indicator mark 2615. There can be multiple second grooves 2614, and the provision of the second grooves 2614 enhances the aesthetic appearance of the button 26. The provision of the indicator mark 2615 is used to indicate the sliding direction of the button 26. For other structures of the adjustment member 24 shown in Figure 17, please refer to the structure of the adjustment member 24 shown in Figure 9, and will not be repeated here.

[0112] As shown in Figure 18, Figure 18 is a cross-sectional view of the wristband 20 shown in Figure 16 along X1-X1. The second connecting band 212 includes a first connecting block 2123, a second connecting block 2124, a third connecting block 2125, a first operating key 2126, a first connecting rod 2127, a third elastic member 2128, and a second connecting rod 2129, which are arranged in sequence. The first connecting block 2123, the second connecting block 2124, and the third connecting block 2125 are detachably connected via the first operating key 2126, the first connecting rod 2127, the third elastic member 2128, and the second connecting rod 2129. The first operating key 2126 and the first connecting rod 2127 can be fixedly connected. The first connecting rod 2127, the third elastic member 2128 and the second connecting rod 2129 are arranged in sequence, one end of the first connecting rod 2127 extends into the first connecting block 2123, the other end of the first connecting rod 2127 extends into the second connecting block 2124 and abuts against the third elastic member 2128, and the end of the second connecting rod 2129 facing away from the third elastic member 2128 extends into the third connecting block 2125.

[0113] It can be understood that when the first operation key 2126 is slid toward the side where the third connecting block 2125 is located, the first operation key 2126 drives the first connecting rod 2127 to slide toward the side where the third connecting block 2125 is located, and the first connecting rod 2127 compresses the third elastic member 2128. The end of the first connecting rod 2127 away from the third elastic member 2128 moves out of the first connecting block 2123, realizing the detachable connection between the first connecting block 2123 and the second connecting block 2124, and then the end of the second connecting rod 2129 away from the third elastic member 2128 moves out of the third connecting block 2125, realizing the detachable connection between the first connecting block 2123 and the third connecting block 2125.

[0114] As shown in Figure 19, Figure 19 is a cross-sectional view of the wristband 20 shown in Figure 16 along X2-X2. The second connecting band 212 includes a fourth connecting block 212-1, which includes a first block 212-2, a second block 212-3, and a third block 212-4 fixedly connected in sequence. The second connecting band 212 also includes a second operating key 212-5, a third connecting rod 212-6, a fourth elastic member 212-7, a fifth elastic member 212-8, a fourth connecting rod 212-9, a sixth elastic member 212-10, and a seventh elastic member 212-11. The fourth elastic member 212-7 is sleeved around the third connecting rod 212-6, the fifth elastic member 212-8 is sleeved around the fourth connecting rod 212-9, and the sixth elastic member 212-10 and the seventh elastic member 212-11 are located at opposite ends of the second operating key 212-5. One end of the second operating key 212-5 cooperates with the third connecting rod 212-6, and the other end of the second operating key 212-5 cooperates with the fourth connecting rod 212-9. The second operating key 212-5 controls the movement of the third connecting rod 212-6 and the fourth connecting rod 212-9.

[0115] When the second operation key 212-5 is pressed downward, the sixth elastic member 212-10 and the seventh elastic member 212-11 are compressed, the third connecting rod 212-6 and the fourth connecting rod 212-9 approach each other, the third connecting rod 212-6 and the fourth connecting rod 212-9 move out of the watch body 10 of the wearable device 100, and the second connecting band 212 is no longer connected to the watch body 10 of the wearable device 100; when the second operation key 212-5 is no longer pressed, the second operation key 212-5 is in the sixth elastic member 212-10 and the seventh elastic member 212-11 are compressed, the third connecting rod 212-6 and the fourth connecting rod 212-9 move closer to each other, and the third connecting rod 212-6 and the fourth connecting rod 212-9 move out of the watch body 10 of the wearable device 100, and the second connecting band 212 is no longer connected to the watch body 10 of the wearable device 100; The second operating key 212-5 moves upward under the action of the elastic force of the elastic member 212-10 and the seventh elastic member 212-11, and the inclined surfaces at both ends of the second operating key 212-5 act on the third connecting rod 212-6 and the fourth connecting rod 212-9 respectively, so that the third connecting rod 212-6 and the fourth connecting rod 212-9 move away from each other, and the third connecting rod 212-6 and the fourth connecting rod 212-9 respectively extend into the watch body 10 of the wearable device 100, and the second connecting belt 212 is connected to the watch body 10 of the wearable device 100.

[0116] In the embodiment of the present application, the adjustment member 24 is arranged to slide in the shell 23, and the clamping portion 271 can be moved from one groove 2312 to another groove 2312, so that the user can fine-tune the overall length of the wristband 20 anytime and anywhere according to his or her own usage needs without the aid of special tools, thereby improving the user experience.
