Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wearable devices, in particular to a watchband, a watchband assembly and a wearable device. BACKGROUND

[0002] With the development of technology, more and more smart wearable devices have emerged, and these smart wearable devices, such as bracelets and watches, all use watchbands. For traditional watchbands, there are generally buckle type watchbands and split type chain watchbands.

[0003] The buckle type watchband is affected by the hole spacing, and the length of the watchband cannot be quickly adjusted after buckling, so it is difficult to achieve a comfortable wearing effect. Moreover, the traditional buckle type watchband has a needle buckle, and the front end of the needle buckle is likely to scratch the user's finger skin when the user adjusts the length of the watchband, especially for children users, whose skin is more delicate and more likely to be scratched.

[0004] The length of each watch chain of the split type chain watchband is fixed, and there are few devices that can adjust the length of the watchband. At this time, if the user wants to adjust the length of the watchband, he needs to buy additional accessories or remove the excess watch chain. If the length of the watchband is too long, the user needs to use a tool to eject the clamping needle between the two adjacent chain links; if the length of the watchband is too short, the user needs to add a chain link and use a tool to insert the clamping needle between the chain link and the adjacent chain link. The whole adjustment process is complex and may not be able to achieve the appropriate length, and repeated adjustment is required to confirm, which affects the use performance of the smart wearable device. Especially for children users, it is difficult for them to operate alone, and they may be injured by the tool when ejecting or inserting the clamping needle, which is very inconvenient to adjust and has great safety hazards, and the user experience is poor.

[0005] Therefore, how to improve the technical defects existing in the prior art has always been a problem to be solved by ordinary skilled in the art. SUMMARY

[0062] In the embodiments shown in the drawings, the indications of the directions (such as up, down, left, right, front and back) are used to explain the structure and movement of various components of the present application, which are not absolute but relative. When these components are in the position shown in the drawings, these descriptions are appropriate. If the position of these components changes, the indications of these directions also change accordingly.

[0063] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0064] According to one specific embodiment of the present application, referring to Figures 1 to 11 A watchband, a watchband assembly and a wearable device, wherein the watchband specifically can include a body and an adjusting device arranged at the end of the body. The adjusting device specifically can include a shell 100, an adjusting member 200, a transmission member 300 and a limiting member 400. The shell 100 is formed with a cavity, and the cavity is provided with an opening 130 on the side facing the body. One end of the transmission member 300 is fixed to the body, and the other end is slidably arranged in the cavity through the opening 130, and the transmission member 300 is provided with a sliding rail 310, and the sliding rail 310 is provided with a plurality of tooth blocks 311 along the length direction of the sliding rail 310. The adjusting member 200 includes a first operation part 210 and a ratchet wheel 220 arranged on the first operation part 210, and the first operation part 210 is used to drive the ratchet wheel 220 to rotate, so that the plurality of tooth blocks 311 can be selectively engaged with the ratchet wheel 220, thereby enabling the transmission member 300 to drive the body to move. The limiting member 400 includes an abutting part 410 and a limiting block 420 movably arranged on the abutting part 410, and the abutting part 410 is fixed in the cavity, and when the limiting block 420 is in abutting cooperation with the transmission member 300, the limiting block 420 can limit the transmission member 300 to drive the body to move away from the shell 100.

[0065] In this embodiment, the transmission member 300 is arranged to be driven by the adjusting member 200 to move the watchband body, thereby achieving the adjustment of the length of the watchband. The whole process is convenient and fast, and the user only needs to rotate the first operation part 210 of the adjusting member 200. At the same time, the movable limiting block 420 is arranged in the patent, and when the limiting block 420 is in abutting cooperation with the transmission member 300, the limiting block 420 can limit the transmission member 300 to drive the body to move away from the shell 100. In this way, when the user adjusts the length of the watchband through the adjusting member 200, the limiting cooperation between the limiting member 400 and the transmission member 300 can effectively prevent the watchband from loosening due to the user's vigorous movement, and the user's comfort is high. Conversely, when the user needs to adjust the length of the watchband, the movable limiting block 420 is arranged not to be in abutting cooperation with the transmission member 300, so that the watchband body can be driven by the transmission member 300 to move away from the shell 100. The operation is simple and has high practicability.

[0066] Referring to Figures 1 to 7 In order to facilitate the disassembly and replacement of the parts inside the cavity for future maintenance, the shell 100 should adopt a split structure. In one embodiment, the shell 100 specifically can include an upper shell 110 and a lower shell 120, and the upper shell 110 and the lower shell 120 jointly form the above-mentioned cavity. Of course, in actual production, the shell 100 can also have other various arrangement modes, which can disassemble and replace the parts inside the cavity, and the present application is not limited thereto, and all falls within the protection scope of the present application.

[0067] At this time, referring toFigure 2 , Figure 6 and Figure 8 The upper housing 110 has a mounting hole 111 on the side away from the lower housing 120. The first operating part 210 is rotatably fixed to the mounting hole 111, and the side of the first operating part 210 facing the cavity has a first mounting station 211 for fixing the ratchet 220. The first mounting station 211 should have an anti-rotation structure, such as setting a locking block or slot in the mounting station as an anti-rotation structure, or setting the mounting station as a non-circular structure to play an anti-rotation role, or setting a pin that can pass laterally through the mounting station and the part where the ratchet 220 is connected, so as to ensure that the ratchet 220 and the first operating part 210 rotate synchronously. Of course, in actual production, the mounting station can also have other settings, which will not be elaborated here, and are all within the protection scope of this invention. It is worth noting that the end of the ratchet 220 that is connected to the mounting station should be adapted to the contour of the mounting station.

[0068] Specifically, the ratchet 220 is fixed to the installation position by a screw. At this time, the first operating part 210 can cover the screw to improve the overall aesthetics of the adjusting part 200.

[0069] Specifically, see Figure 7 , Figure 9 , Figure 10 and Figure 11 The docking portion 410 is fixed to the side of the lower housing 120 facing the upper housing 110, and the side of the docking portion 410 facing the lower housing 120 is provided with a second mounting position 411 for fixing the limiting block 420. One end of the limiting block 420 is provided with a limiting boss 421 facing the transmission member 300, and the other end is provided with a second operating portion 422. The docking portion 410 is provided with a first clearance hole 412 for the limiting boss 421 to move, and the housing 100 is provided with a second clearance hole 150 for the second operating portion 422 to pass through. It is worth noting that at least one first elastic member 4111 is fixed in the second mounting position 411, and the free end of the first elastic member 4111 abuts against the end of the limiting block 420 away from the second operating portion 422. At this time, the transmission component 300 is provided with a limiting groove 320 distributed along the length of the slide rail 310 on the side facing the limiting boss 421. The limiting groove 320 is provided with a number of evenly spaced grooves 321 on the side near the second operating part 422. The grooves 321 are adapted to the limiting boss 421, and the grooves 321 can be selectively engaged with the limiting boss 421.

[0070] In this embodiment, see Figure 11When the first elastic member 4111 is not subjected to force and is in a natural state, the limiting boss 421 should be engaged with the groove 321 to limit the movement of the body towards the direction away from the shell 100 by the transmission member 300; when the first elastic member 4111 is subjected to pressure or tension, the limiting boss 421 is disengaged from the groove 321, and the body can be moved towards the direction away from the shell 100 by the transmission member 300. In the embodiment, the groove 321 is arranged on the side of the limiting sliding groove 320 close to the second operation part 422, so when the user presses the second operation part 422, the first elastic member 4111 is subjected to pressure, and the limiting boss 421 is disengaged from the groove 321. Of course, in some embodiments, the groove 321 can also be arranged on the side of the limiting sliding groove 320 away from the second operation part 422, at this time, when the user pulls the second operation part 422, the first elastic member 4111 is subjected to tension, and the limiting boss 421 is disengaged from the groove 321. Considering the convenience in specific operation, the groove 321 provided in the embodiment is arranged on the side of the limiting sliding groove 320 close to the second operation part 422.

[0071] To improve the structural strength of the limiting boss 421, the part away from the groove 321 can be widened and thickened without affecting the original matching relationship, which is not limited herein and is within the protection scope of the present application.

[0072] It is worth noting that in the embodiment, if the length of the limiting sliding groove 320 is less than the length of the sliding rail 310, then the length of the limiting sliding groove 320 is the length of the watchband that can be adjusted. Conversely, if the length of the limiting sliding groove 320 is greater than the length of the sliding rail 310, then the length of the sliding rail 310 is the length of the watchband that can be adjusted. In actual production, the length range of the watchband that can be adjusted can be changed by changing the length of the limiting sliding groove 320 and the sliding rail 310.

[0073] If the length range of the watchband that can be adjusted is large, then the wearable device can be suitable for users of different body types and wrist sizes, and the applicability is stronger. Moreover, part of the population can directly adjust the length of the watchband to the longest, so as to put on and take off the wearable device.

[0074] In addition, in the embodiment, the interval between each adjacent two grooves 321 is the minimum length that can be adjusted by the user each time, and the length of the watchband can be fine-tuned by reducing the interval between the adjacent two grooves 321. It is worth noting that the several grooves 321 are uniformly and spacedly arranged, which is more conducive to the user to control the length of the watchband, so that the wearable device can better adapt to the wrist of the user, and the comfort of the user and the use performance of the wearable device are improved.

[0075] Specifically, referring to Figure 1 , Figure 2 , Figure 7 and Figure 11The number of the limiting blocks 420 is two, and the limiting blocks 420 are respectively located on two sides of the slide rail 310. The first elastic member 4111 enables the limiting block 420 to move towards the slide rail 310 and to move away from the slide rail 310. In this way, when the user adjusts the length of the watchband, the user can press the second operation part 422 by the thumb and the middle finger, and can adjust the length of the watchband by the index finger. The whole adjusting process is convenient and fast, is beneficial to the single-handed operation of the user, has high comfort and strong safety performance, and can exercise the flexibility of the fingers of the child user to a certain extent. Of course, one limiting block 420 can be arranged on one side of the slide rail 310. At this time, if the user needs to adjust the length of the watchband, the user can press the second operation part 422 by the thumb, and can adjust the length of the watchband by the index finger.

[0076] In one embodiment, referring to Figure 10 , the first elastic member 4111 is a spring, and the limiting block 420 is provided with a first clamping table 423 away from the second operation part 422. At this time, the first elastic member 4111 is sleeved on the first clamping table 423 away from the second installation station 411, and is fixedly connected with the first clamping table 423.

[0077] Of course, in actual production, the first elastic member 4111 can also be a spring sheet, and the present embodiment only lists a feasible scheme, which is not limited herein, and is within the protection scope of the present application.

[0078] Specifically, referring to Figure 6 , Figure 7 and Figure 11 , the limiting boss 421 is provided with a first driving surface 4211 and a first locking surface 4212 arranged oppositely, and the first driving surface 4211 is arranged on the side of the limiting boss 421 facing the opening 130. The distance between the side of the first driving surface 4211 close to the second operation part 422 and the opening 130 is greater than the distance between the side of the first driving surface 4211 away from the second operation part 422 and the opening 130. Correspondingly, the distance between the side of the first locking surface 4212 close to the second operation part 422 and the opening 130 is not less than the distance between the side of the first locking surface 4212 away from the second operation part 422 and the opening 130.

[0079] The groove 321 is also provided with a second driving surface 3211 and a second locking surface 3212 corresponding to the first driving surface 4211 and the first locking surface 4212. Specifically, when the limiting boss 421 is engaged into a certain groove 321, the first driving surface 4211 of the limiting boss 421 is opposite to the second driving surface 3211 of the corresponding groove 321, and the first locking surface 4212 of the limiting boss 421 is opposite to the second locking surface 3212 of the corresponding groove 321. At this time, if the transmission member 300 moves towards the shell 100, the second driving surface 3211 of the groove 321 will move towards the shell 100 along the first driving surface 4211 and press the limiting boss 421, so that the limiting boss 421 moves towards the slide rail 310, thereby separating the limiting boss 421 from the groove 321. When the limiting boss 421 is no longer pressed, the first elastic member 4111 drives the limiting boss 421 to reset and engage into the adjacent groove 321, thereby adjusting the length of the watchband. In this way, the user can directly rotate the first operation part 210 to complete the adjustment without pressing the second operation part 422 with fingers, and the operation is more simple and convenient. If the transmission member 300 moves away from the shell 100, the second locking surface 3212 of the groove 321 will abut against the first locking surface 4212, so that the groove 321 and the limiting boss 421 are locked, thereby limiting the movement of the transmission member 300. In this way, only when the user presses the pressing member, the transmission member 300 can move away from the shell 100, thereby avoiding the situation that the wearable device becomes loose or even falls off the user's hand due to the user's vigorous movement.

[0080] Preferably, referring to Figures 4 to 7 and Figure 9 and Figure 11 The transmission member 300 is provided with a guide boss 330 distributed along the length direction of the slide rail 310 on both sides of the abutment part 410, and the abutment part 410 is provided with a first guide groove 413 corresponding to the guide boss 330.

[0081] In this embodiment, the guide boss 330 and the corresponding first guide groove 413 facilitate the stable movement of the transmission member 300, so that the user will not experience the phenomenon of jamming when adjusting the length of the watchband, and the comfort of the user during use is improved. Correspondingly, the second guide groove 131 is provided at the positions corresponding to the two guide bosses 330 on the edge profile of the opening 130, and the second guide groove 131 also cooperates with the two guide bosses 330 to further improve the stability of the transmission member 300, so that the user will not experience the phenomenon of jamming when adjusting the length of the watchband, and the comfort of the user during use is improved.

[0082] Further, referring to Figures 5 to 7The docking portion 410 is provided with at least one first abutting boss 414 distributed along the length direction of the slide rail 310, which abuts against the side of the transmission member 300 facing the docking portion 410.

[0083] The first abutting boss 414 can reduce the contact area between the transmission member 300 and the docking portion 410 as much as possible, thereby reducing the friction force suffered by the transmission member 300 during movement, further avoiding the occurrence of the jamming phenomenon, and improving the use performance of the watchband.
