[0022] This application provides a wearable device 700. Please refer to [link / reference]. Figure 1 The wearable device 700 may include a connecting component 500 and a wearable device body 70, with the opposite ends of the connecting component 500 connected to the wearable device body 70. The wearable device body 70 may be a smartwatch, a bracelet, a headband, or other similar device. The following description uses a smartwatch as an example. The connecting component 500 can be used to secure the wearable device body 70. That is, the connecting component 500 can fix the wearable device body 70 to the user's wearing area (e.g., wrist), and the length of the connecting component 500 can be adjusted according to the circumference of the user's wearing area to suit the user's wearing needs.

[0023] Please see Figure 2The connecting component 500 may include a connecting strap 50 and at least one buckle component 400. The connecting component 500 is connected to the wearable device body 70 to form a wearing space for a user to wear. There may be one or two buckle components 400. When there is one buckle component 400, one end of the connecting strap 50 is movably connected to the buckle component 400 and connected to the wearable device body 70 through the buckle component 400. The other end of the connecting strap 50 has an interface for direct connection to the wearable device body 70. When there are two buckle components 400, both ends of the connecting strap 50 are connected to the buckle components 400 and connected to the wearable device body 70 through the buckle components 400 respectively. At least one end of the connecting strap 50 is movably connected to the buckle component 400, and the other end may be fixedly or movably connected to the buckle component 400. One end of the connecting strap 50 that is movably connected to the buckle assembly 400 can be used to adjust the length of the wearing space formed by the connecting strap 50, so that the size of the wearing space is adapted to the wearing part.

[0024] Please see Figure 3 The buckle assembly 400 may include a buckle 100 and an adjusting member 200, the adjusting member 200 being detachably connected to the buckle 100. For example, the adjusting member 200 may be threadedly connected to the buckle 100. The buckle 100 may be made of metal or plastic. The buckle 100 and the adjusting member 200 may be made of the same or different materials, which is not specifically limited here. The buckle 100 may be mounted on the wearable device body 70. The buckle 100 has a connection space 15, through which at least one end of the connecting strap 50 is movably inserted. For example, as shown... Figure 2 As shown, the connecting strap 50 can be inserted into the buckle 100 from the side away from the user's wearing area, pass over the adjusting member 200, and then exit the buckle 100 again. It is then folded and attached to the side closer to the user's wearing area, thus connecting the connecting strap 50 to the adjusting member 200 to adjust the tightness of the connecting strap 50. The adjusting member 200 and buckle 100 are detachably connected, allowing the user to replace the adjusting member 200 as needed to match different connecting straps 50 (e.g., connecting straps 50 of different thicknesses), which improves the adaptability of the buckle 100.

[0025] Please see Figure 4The buckle 100 has a first direction and a second direction that are different from each other. Optionally, the first direction and the second direction can be set to be perpendicular to each other, or the first direction and the second direction can be set to form a certain angle with each other, without specific limitation. The buckle 100 includes a first frame 11, a second frame 12, a third frame 13, and a fourth frame 14. The first frame 11 and the second frame 12 are spaced apart along the first direction, and the third frame 13 and the fourth frame 14 are spaced apart along the second direction. The third frame 13 and the fourth frame 14 respectively connect the first frame 11 and the second frame 12, so that the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 enclose a connection space 15 for assembling the adjustment component 200. The shape of the connection space 15 can be designed as needed to meet the user's personalized needs. For example, the outer contour of the connection space 15 can be approximately trapezoidal or rectangular. The first frame 11 is used to connect with the wearable device body 70. The third frame 13 and the fourth frame 14 are respectively provided with connecting holes 16 extending in the second direction. The connecting holes 16 are used for the adjustment member 200 to be detachably connected to the buckle 100.

[0026] The buckle 100 provided in this application has connecting holes 16 extending in the second direction on the third frame 13 and the fourth frame 14 respectively. The adjusting member 200 can be snapped into the connecting hole 16, thereby facilitating the disassembly and assembly of the adjusting member 200. This allows the user to easily replace the adjusting member 200 to match different connecting straps 50 as needed, which helps to improve the adaptability of the buckle 100.

[0027] The connection method between the first frame 11 and the wearable device body 70 can be varied to accommodate different interfaces of the wearable device body 70. In some embodiments, such as Figure 4 As shown, the first frame 11 is provided with a first mounting hole 111, which is used to mount the buckle 100 onto the wearable device body 70. The extending direction of the first mounting hole 111 is perpendicular to the extending direction of the adjusting member 200. When the buckle 100 is connected to the wearable device body 70, a corresponding protrusion on the wearable device body 70 can pass through or be inserted into the first mounting hole 111, and the protrusion will fasten the buckle 100 onto the wearable device body 70.

[0028] In some embodiments, such as Figure 5 As shown, a second mounting hole 112 is provided on the first frame 11, which is used to mount the buckle 100 onto the wearable device body 70. The extending direction of the second mounting hole 112 is parallel to the extending direction of the adjusting member 200. When the buckle 100 is connected to the wearable device body 70, the connecting shaft on the wearable device body 70 can pass through or be inserted into the second mounting hole 112, and the connecting shaft fixes the buckle 100 onto the wearable device body 70.

[0029] In some embodiments, in a reference section perpendicular to the second direction, the size of the connecting hole 16 is larger than the size of the corresponding end of the adjusting member 200, so that the end of the adjusting member 200 can be inserted into the corresponding connecting hole 16 with a clearance fit. With this configuration, in the reference section perpendicular to the second direction, during the assembly and disassembly of the adjusting member 200, there is a certain amount of space between the end of the adjusting member 200 and the wall of the connecting hole 16, making the installation or disassembly of the adjusting member 200 more convenient and improving the ease of replacing the adjusting member 200.

[0030] In some embodiments, the connecting hole 16 can be circular, so that there is a certain amount of room for movement between the end of the adjusting member 200 and the hole wall of the connecting hole 16 in all directions, making it easier to install or remove the adjusting member 200 and improving the convenience of replacing the adjusting member 200.

[0031] In some embodiments, within a reference section perpendicular to the second direction, the dimension of the connecting hole 16 along the first direction is larger than the dimension of the connecting hole 16 along the perpendicular direction of the first direction. That is, the shape of the connecting hole 16 is elongated. Optionally, the shape of the connecting hole 16 can be rectangular or elliptical. For example, as... Figure 6 As shown, when the end of the adjusting member 200 is inserted into the corresponding connecting hole 16, in a reference section perpendicular to the second direction, the end of the adjusting member 200 and the connecting hole 16 have a first gap 131 in the first direction, and a second gap 132 in the direction perpendicular to the first direction. This allows the adjusting member 200 to have a certain amount of movement in both the first direction and the direction perpendicular to the first direction, thereby facilitating the installation or removal of the adjusting member 200. The maximum value of the first gap 131 is greater than the maximum value of the second gap 132. With this configuration, the adjustment member 200 has a larger range of motion in the first direction than in the second direction. On the one hand, the adjustment member 200 can slide in the first direction and adjust its position according to the thickness of the connecting strap 50, so that the buckle 100 can match connecting straps 50 of different thicknesses, which helps to improve the adaptability of the buckle 100. On the other hand, the adjustment member 200 has a relatively smaller range of motion in the second direction, which can reduce the shaking that occurs in the second direction after the adjustment member 200 is assembled, thereby improving wearing comfort. Thirdly, by making full use of the space of the buckle 100 in the first direction to increase the size of the connecting hole 16 and controlling the size of the connecting hole 16 in the second direction, it is not only convenient to disassemble and assemble the adjustment member 200, but also helps to reduce the size of the buckle 100 in the second direction.

[0032] Please see Figure 7A first gap 113 is formed between the first frame 11 and the adjusting member 200, and a second gap 114 is formed between the second frame 12 and the adjusting member 200. When the connecting strap 50 is connected to the buckle 100, the connecting strap 50 can pass through the first gap 113 from the side away from the user's wearing part, fold over, cross the adjusting member 200, and exit through the second gap 114, and then be attached to the side close to the user's wearing part. When the connecting strap 50 is stretched, it compresses the folded connecting strap 50, causing the adjusting member 200 to slide towards the second frame 12. The relative position of the adjusting member 200 to the second frame 12 changes according to the thickness of the connecting strap 50, and it moves closer to the second frame 12 with the tension of the connecting strap 50. The connecting strap 50 generates friction due to the mutual contact between the adjusting member 200 and the second frame 12. This friction prevents the connecting strap 50 from slipping off the adjusting member 200, thereby reducing the shaking of the connecting strap 50 after wearing and fixing connecting straps 50 of different thicknesses to the adjusting member 200.

[0033] In some embodiments, the connecting strap 50 is inserted through the first gap 113 and the second gap 114 with an interference fit. This arrangement can further increase the friction between the connecting strap 50 and the buckle 100 and the adjusting member 200. The connecting strap 50 cooperates with the buckle 100 and the adjusting member 200 to prevent the connecting strap 50 from slipping off the adjusting member 200, which helps to reduce the shaking of the connecting strap 50 after wearing, thereby improving wearing comfort.

[0034] In some embodiments, such as Figure 6 As shown, the first frame 11 is used to connect to the wearable device body 70. The ends of the third frame 13 and the fourth frame 14 near the first frame 11 are configured to be bent relative to the second frame 12 towards the side closer to the wearer when worn. This configuration creates a certain angle between the ends of the third frame 13 and the fourth frame 14 near the first frame 11 and the ends near the second frame 12, making the buckle 100 more ergonomic and adaptable to the user's wearing area. The increased contact area between the buckle 100's frame and the wearer effectively distributes pressure, reducing the pressure that may occur during prolonged wear, thereby improving the wearing comfort of the buckle 100.

[0035] In some embodiments, such as Figure 4As shown, the ends of the third frame 13 and the fourth frame 14 that are connected to the second frame 12 form a receiving groove 121. In the wearing state, the opening of the receiving groove 121 is located on the side of the second frame 12 away from the wearing area, and the receiving groove 121 can accommodate at least a portion of the connecting strap 50. This arrangement, on the one hand, restricts the movement of the connecting strap 50 in the second direction at the ends of the third frame 13 and the fourth frame 14 connected to the second frame 12, thereby reducing the swaying of the connecting strap 50 and improving wearing comfort; on the other hand, the fact that at least a portion of the connecting strap 50 can be accommodated in the receiving groove 121 allows the connecting strap 50 to fit more closely to the wearing area, effectively distributing the pressure of the connecting strap 50 and reducing the pressure that may occur during prolonged wear, thereby further improving wearing comfort.

[0036] Specifically, such as Figure 7 As shown, when the connecting strap 50 is connected to the buckle 100, the connecting strap 50 can pass through the first gap 113 from the side away from the user's wearing part, fold over the adjusting member 200 and exit through the second gap 114, and then be attached to the side close to the user's wearing part and partially accommodated in the receiving groove 121. The connecting strap 50 is fixed to the side of the second frame 12 away from the wearing part by the adjusting member 200 and the second frame 12. The connecting strap 50 bends downward along the outside of the second frame 12 and is at least partially embedded in the receiving groove 121, so that the side of the connecting strap 50 away from the user's wearing part can remain flat, reducing pressure and further improving wearing comfort. It also ensures flatness during wear, making the overall appearance of the device more concise and aesthetically pleasing.

[0037] In some embodiments, such as Figure 4 As shown, the two connecting holes 16 connect the connecting space 15 and the external space of the buckle 100 along the second direction. Through-hole connecting holes 16 are provided on the third frame 13 and the fourth frame 14. On the one hand, the through-hole connecting holes 16 facilitate user observation and operation of the adjusting component 200, making it easier to adjust or replace the connecting band 50; on the other hand, the through-hole connecting holes 16 facilitate the processing of the buckle 100 (e.g., facilitating demolding during injection molding), thereby improving production efficiency.

[0038] In some embodiments, one end of each of the two connecting holes 16 is connected to the connecting space 15, and in the second direction, the size of the connecting holes 16 is smaller than the size of the third frame 13 and the fourth frame 14, respectively. Blind-hole type connecting holes 16 are provided on the third frame 13 and the fourth frame 14, and the blind-hole type connecting holes 16 do not connect the connecting space 15 with the external space of the buckle 100. This configuration, on the one hand, prevents larger dust and moisture from entering the connecting space 15 and the adjusting member 200, improving the dustproof and moisture-proof capability of the buckle 100; on the other hand, the blind-hole type connecting holes 16 only open on the inner side of the third frame 13 and the fourth frame 14 and do not penetrate to the outer surface, leaving no visible holes on the outside, thus keeping the appearance of the buckle 100 simple and flat, giving the buckle 100 an aesthetic and integrated look.

[0039] In some embodiments, such as Figure 8 As shown, the adjusting member 200 includes a middle portion 23, a first connecting end 21, and a second connecting end 22. The first connecting end 21 of the adjusting member 200 is connected to one end of the middle portion 23 in a second direction, and the second connecting end 22 is connected to the other end of the middle portion 23 in the second direction. The middle portion 23 of the adjusting member 200 is located within the connecting space 15 of the buckle 100. The first connecting end 21 passes through the connecting hole 16 of the third frame 13, and the second connecting end 22 passes through the connecting hole 16 of the fourth frame 14.

[0040] In some embodiments, one of the first connecting end 21 and the second connecting end 22 of the adjusting member 200 is configured to be retractable relative to the middle portion 23, while the other is fixedly connected to the middle portion 23. Optionally, an elastic element, knob, or snap-fit ​​may be provided between the connecting end and the middle portion 23. Specifically, the user can directly operate the retractable connecting end to retract it towards the middle portion 23, shortening the overall length of the adjusting member 200 and providing sufficient operating space for installation or disassembly, allowing the adjusting member 200 to easily be inserted into or removed from the connecting hole 16 on the buckle 100 frame. After installation and positioning are completed, the user releases the connecting end, and the adjusting member 200 extends outward, returning to its original length. At this time, the first connecting end 21 and the second connecting end 22 of the adjusting member 200 are respectively engaged in the connecting holes 16 of the third frame 13 and the fourth frame 14, forming a stable connection, thereby effectively preventing it from accidentally coming off the buckle 100 during operation. This type of adjustment component 200 can be adjusted in length from one side. Its structure is relatively simple, which facilitates the processing, manufacturing, and subsequent maintenance of the adjustment component 200.

[0041] In some embodiments, the first connecting end 21 of the adjusting member 200 is configured to be retractable relative to the middle portion 23, and the second connecting end 22 is also configured to be retractable relative to the middle portion 23, so that the user can adjust the length of the adjusting member 200 from either side of the adjusting member 200, thereby facilitating the disassembly and assembly of the adjusting member 200.

[0042] In some embodiments, such as Figure 8 As shown, in a reference section perpendicular to the second direction, the size of the connecting hole 16 is larger than the size of the corresponding first connecting end 21 or second connecting end 22, facilitating the insertion of the first connecting end 21 and the second connecting end 22 of the adjusting member 200 into the connecting hole 16. Simultaneously, the size of the connecting hole 16 is smaller than the size of the intermediate portion 23 in at least one direction, allowing the intermediate portion 23 of the adjusting member 200 to engage with the connecting end in the connecting hole 16. Optionally, the size difference between the first connecting end 21 and the second connecting end 22 and the intermediate portion 23 can be abruptly or gradually changed. Specifically, by using the size difference between the first connecting end 21 and the second connecting end 22 and the intermediate portion 23, one end of the adjusting member 200 is inserted into the connecting hole 16, providing sufficient operating space for installing or removing the other end, allowing the adjusting member 200 to be inserted into or removed from the connecting hole 16 on the buckle 100 frame. The first connecting end 21 and the second connecting end 22 of the adjusting member 200 are respectively engaged in the connecting holes 16 of the third frame 13 and the fourth frame 14, forming a stable connection, thereby effectively preventing it from accidentally coming off the buckle 100 during operation. This dimensional difference allows the adjusting member 200 to be more reliably engaged in the connecting hole 16, preventing it from easily coming off and ensuring the reliability of the adjusting member 200 and the buckle 100.

[0043] Please see Figure 9 , Figure 10 The connecting strap 50 may be strip-shaped, having a first end 51 that connects to the buckle 100 and a second end 52 that connects to the main body 70 of the wearable device. The connecting strap 50 may be made of silicone, plastic, or other flexible materials. When the first end 51 of the connecting strap 50 is connected to the buckle 100, the connecting strap 50 can be fixed to the buckle 100, and the wearing length of the connecting strap 50 can be adjusted through the buckle 100.

[0044] Optionally, a fixing post 53 is provided on the first end 51 of the connecting strap 50, and a plurality of fixing holes 54 are provided between the first end 51 and the second end 52. After the first end 51 is connected to the buckle 100 and folded, the fixing post 53 can be inserted into the fixing hole 54. The hole wall of the fixing hole 54 can prevent the fixing post 53 from sliding, thereby fixing the connecting strap 50 to the buckle 100.

[0045] Optionally, such as Figure 9As shown, the connecting strap 50 is provided with a sleeve 55, which is fitted onto the connecting strap 50. After the connecting strap 50 is connected to the buckle 100 and folded, the end of the connecting strap 50 connected to the buckle 100 passes through the sleeve 55. The sleeve 55 and the connecting strap 50 are interference-fitted to limit the end of the connecting strap 50 connected to the buckle 100 within the sleeve 55, thereby preventing the connecting strap 50 from sliding and thus fixing the connecting strap 50 to the buckle 100.

[0046] The above description is only a part of the embodiments of this utility model, and does not limit the scope of protection of this utility model. Any equivalent device or equivalent process transformation made based on the content of this utility model specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this utility model.
