Description

TECHNICAL FIELD

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

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

[0003] The buckle type watchband is affected by the hole spacing, and cannot be quickly adjusted in length after buckling, which 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 tender and more likely to be scratched.

[0004] The length of each watchband of the split type chain watchband is fixed, and there are few devices that can adjust the length of the watchband. At this time, the user needs to purchase additional accessories or remove the excess watchband if he wants to adjust the length of the watchband. 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 links; if the length of the watchband is too short, the user needs to add a link and use a tool to insert the clamping needle between the link and the adjacent link. The whole adjustment process is complex and may not achieve the appropriate length, and needs to be repeatedly adjusted and confirmed, 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. The adjustment is very inconvenient and has great safety hazards, and the user experience is poor.

[0069] According to a specific embodiment provided by the present application, see Figures 1 to 13 A watchband 500 head grain and wearing equipment. Wherein, the watchband 500 head grain can specifically include a shell 100, a moving piece 200, an adjusting assembly 300 and a limiting assembly 400. The shell 100 has a cavity 110 with an opening, the moving piece 200 is movably arranged in the cavity 110, and the moving piece 200 is provided with a main slide 210, and the main slide 210 is provided with a plurality of tooth blocks 211 along the length direction of the main slide 210. The adjusting assembly 300 includes a rotating piece and a pressing piece, one end of the rotating piece is provided with a gear 320, and a plurality of tooth blocks 211 can be selectively engaged with the gear 320 to drive the moving piece 200 to move along the length direction of the main slide 210, and the pressing piece is movably arranged in the rotating piece. It is worth noting that the limiting assembly 400 is arranged in the cavity 110, and can be operated to be in a first position and a second position under the action of the pressing piece. When the pressing piece is separated from the limiting assembly 400, the limiting assembly 400 is in the first position and cooperates with the moving piece 200, so that the moving piece 200 can be operated to move towards the shell 100. When the pressing piece is in butt joint with the limiting assembly 400, the limiting assembly 400 is in the second position and is separated from the moving piece 200.

[0070] In this embodiment, by setting the main slide 210 and the gear 320 arranged on the rotating member, the user can rotate the rotating member to drive the gear 320 to rotate, so as to drive the moving member 200 to move the shell 100 through the cooperation of the gear 320 and the tooth block 211, thereby changing the length of the head grain of the watchband 500, and realizing the adjustment of the tightness of the wearable device. At this time, if the user does not press the pressing member, the pressing member is separated from the limiting assembly 400, and the limiting assembly 400 is in the first position and cooperates with the moving member 200, so that the moving member 200 can be operatively moved towards the shell 100. In this way, the wearable device can only be tightened but cannot be loosened, which is beneficial to the user to adjust the tightness of the wearable device, and can also avoid the situation that the wearable device is loosened or even separated from the user's hand due to the user's violent movement. On the contrary, if the user presses the pressing member, the pressing member is in abutting cooperation with the limiting assembly 400, and the limiting assembly 400 is in the second position and separated from the moving member 200. At this time, the user can re-adjust the tightness of the wearable device to loosen the wearable device. Specifically, the user can press the pressing member with the thumb and rotate the rotating member with the index finger to adjust the tightness of the wearable device. The whole adjustment process is simple, fast, convenient for single-handed operation, high in comfort and strong in safety performance, and can also exercise the flexibility of the fingers of the child user to a certain extent.

[0071] In order to facilitate the disassembly and replacement of the internal parts of the cavity 110, the shell 100 is in a split type structure. Specifically, the side of the shell 100 away from the adjusting assembly 300 is provided with an opening, and a cover plate 120 is arranged on the opening. In this way, when the user needs to disassemble and replace the internal parts of the cavity 110, the cover plate 120 can be removed first and then operated. Of course, in actual production, the shell 100 can also have various setting modes, as long as the disassembly and replacement of the internal parts of the cavity 110 can be realized, which is not limited herein and is within the protection scope of the present application.

[0072] Specifically, referring to Figure 3 、 Figure 4 and Figures 11 to 13, the pressing member includes a first body 340 and a connecting portion 350, the rotating member includes a second body 310 and a gear 320, and the first body 340 and the second body 310 are both in a rotary body structure. The connecting portion 350 is arranged on a side of the first body 340 facing the second body 310, and the gear 320 is arranged at an end of the second body 310 away from the first body 340. An accommodation groove 311 for accommodating the first body 340 is arranged at an end of the second body 310 facing the first body 340, and a first reset spring 360 is arranged in the accommodation groove 311 and abuts against the first body 340 and an end of the second body 310 facing each other. At this time, a first avoiding hole 330 for the connecting portion 350 to pass through is arranged in the bottom of the accommodation groove 311 and the gear 320, or the first avoiding hole 330 for the connecting portion 350 to pass through is arranged in the bottom of the accommodation groove 311. Correspondingly, the cavity 110 should be provided with a second avoiding hole for the gear 320 and the connecting portion 350 to pass through.

[0073] In the embodiment, when the user presses the pressing member, the pressing member extrudes the limiting assembly 400 downward, so that the limiting assembly 400 is in the second position, and the first reset spring 360 is deformed. In this way, when the user no longer presses the pressing member, the first reset spring 360 returns to the initial state, drives the pressing member to move upward, so that the limiting assembly 400 is in the first position, and automatic reset is realized, which is convenient to operate.

[0074] Specifically, referring to Figure 3 , Figure 4 , Figure 11 and Figure 13 , a mounting boss 370 coaxially arranged is arranged on a side of the first body 340 facing the second body 310 and the bottom of the placing groove, and at this time, the two ends of the first reset spring 360 can be respectively sleeved on the two mounting bosses 370, so that the first reset spring 360 is mounted.

[0075] In one embodiment, referring to Figure 4 , the connecting portion 350 is arranged in the central region of the first body 340, and the gear 320 is arranged in the central region of the second body 310, so that the bottom of the accommodation groove 311 and the gear 320 are both provided with the first avoiding hole 330 for the connecting portion 350 to pass through. At this time, when the user rotates the second body 310, the second body 310 only drives the gear 320 to rotate, and when the user presses the first body 340, the first body 340 only drives the connecting portion 350 to move towards the limiting assembly 400.

[0076] In one embodiment, referring to Figure 3 , Figure 11 and Figure 13When the abutting portion 350 is arranged at the side edge of the first body 340 and the gear 320 is arranged at the central region of the second body 310, the bottom of the accommodating groove 311 is provided with a first avoiding hole 330 through which the abutting portion 350 passes. At this time, the first avoiding hole 330 should be in a circular arc structure, and the arc length thereof should match the adjustable length range of the head of the watchband 500, so as to avoid the interference between the second body 310 and the abutting portion 350 when the second body 310 is rotated. In the embodiment, the abutting portion 350 should be in a circular arc column structure or a cylindrical structure, so as to facilitate the movement of the second body 310 relative to the abutting portion 350. As a preferred, the abutting portion 350 should be in a circular arc column structure, and compared with the cylindrical structure, the contact area between the abutting portion 350 and the limiting assembly 400 is larger, so as to avoid the excessive local stress of the limiting assembly 400, and affect the service performance and service life thereof.

[0077] Specifically, referring to Figure 5 and Figure 12 , the end of the second body 310 away from the first body 340 is provided with a mounting groove 312 for mounting the gear 320, and the mounting groove 312 is provided with a rotation stopping structure 313, so as to ensure the synchronous rotation of the gear 320 and the rotating member. Specifically, the mounting groove 312 can be provided with a clamping block or a clamping groove, so as to form the rotation stopping structure 313, or the mounting groove 312 can be directly provided with a special-shaped or polygonal structure to form the rotation stopping structure 313, which will not be described here in detail, and all of them are within the protection scope of the present application.

[0078] As a preferred, referring to Figure 3 , Figure 11 and Figure 13 , the outer side wall of the first body 340 is provided with at least one first abutting table 341, and the side wall of the accommodating groove 311 is provided with a second abutting table 314, and the second abutting table 314 is arranged around the accommodating groove 311. At this time, the side of the second abutting table 314 facing the bottom of the accommodating groove 311 abuts against the side of the first abutting table 341 away from the abutting portion 350. The two sides of the first abutting table 341 are symmetrically provided with grooves 342 through which the first abutting table 341 can be deformed under stress.

[0079] In the embodiment, by abutting the second abutment 314 to the side of the first abutment 341 away from the docking portion 350 on the side of the groove bottom of the accommodating groove 311, the first body 340 will not be pushed out of the placing groove when it is moved upward under the elastic action of the first return spring 360. In addition, the second abutment 314 is arranged around the accommodating groove 311 in the embodiment, which can ensure that the second abutment 314 abuts against the first abutment 341 during the rotation of the second body 310, so that the second body 310 rotates more smoothly and stably, and the comfort of the user during use is improved. Specifically, the number of the first abutments 341 in the embodiment is four, and they are uniformly and spacedly distributed. At this time, the embodiment is provided with the slots 342 on both sides of the first abutments 341 for the force deformation of the first abutments 341, which is beneficial to the fixed installation of the first body 340 and the second body 310, and is convenient for future maintenance and replacement.

[0080] Preferably, referring to Figure 1 and Figure 2 , the outer side wall of the second body 310 is provided with a plurality of evenly spaced slots 315, which increases the friction between the user's fingertips and the second body 310, facilitates the user to rotate the second body 310, and adjusts the length of the head grain of the watchband 500.

[0081] Further, referring to Figure 4 and Figure 7 , a pressing block 351 can be arranged at the end of the docking portion 350 away from the first body 340. The area of the side of the pressing block 351 facing the limiting assembly 400 is greater than the area of the side of the docking portion 350 facing the limiting assembly 400, so as to increase the contact area between the pressing member and the limiting assembly 400, avoid excessive local stress, and affect the service performance and service life of the pressing member and the limiting assembly 400. Further, a pressing groove 413 can be arranged at the position of the limiting assembly 400 corresponding to the pressing block 351, and the pressing groove 413 is adapted to the contour shape of the pressing block 351.

[0082] Of course, in one embodiment, referring to Figure 3 , Figure 5 , Figure 6 and Figure 8 , a third abutment 412 can also be arranged at the position of the limiting assembly 400 corresponding to the docking portion 350, which is in abutting cooperation with the docking portion 350, and also can avoid the performance reduction of the limiting assembly 400 due to the pressing of the pressing member.

[0083] In one embodiment, referring to Figure 3 , Figure 4 and Figures 6 to 9The limiting assembly 400 is arranged on the side of the cavity 110 away from the adjusting assembly 300, and specifically can include a main plate 410 and a limiting block 420 arranged on the side of the main plate 410 facing the adjusting assembly 300. The side of the moving piece 200 facing the limiting assembly 400 is provided with a plurality of limiting grooves 220 along the length direction of the main slide 210, and the limiting grooves 220 are profile-fitted to the limiting block 420. The plurality of limiting grooves 220 can be selectively and oppositely matched with the limiting block 420.

[0084] Specifically, referring to Figure 3 、 Figure 4 and Figures 6 to 9 , the limiting block 420 is provided with a first guide surface 421 and a first limiting surface 422. The first guide surface 421 is arranged on the side of the limiting block 420 facing the opening of the cavity 110, and the side of the first guide surface 421 facing the opening of the cavity 110 is lower than the side of the first guide surface 421 away from the opening of the cavity 110. The first limiting surface 422 is arranged on the side of the limiting block 420 away from the opening of the cavity 110, and the side of the first limiting surface 422 facing the opening of the cavity 110 is lower than the side of the first limiting surface 422 away from the opening of the cavity 110, or the first limiting surface 422 is perpendicular to the main plate 410.

[0085] Since the limiting grooves 220 are profile-fitted to the limiting block 420, the limiting grooves 220 are also provided with a second guide surface 221 and a second limiting surface 222 corresponding to the first guide surface 421 and the first limiting surface 422. Specifically, when the limiting block 420 is clamped into a certain limiting groove 220, the first guide surface 421 thereof is opposite to the second guide surface 221 of the corresponding limiting groove 220, and the first limiting surface 422 thereof is opposite to the second limiting surface 222 of the corresponding limiting groove 220. At this time, if the moving piece 200 moves towards the shell 100, the second guide surface 221 of the limiting groove 220 will move towards the shell 100 along the first guide surface 421 and press the limiting block 420 downwards, so that the limiting groove 220 and the limiting block 420 are separated. When the limiting block 420 is not under pressure, the limiting block 420 is clamped into an adjacent limiting groove 220, so as to adjust the length of the head grain of the watchband 500. At this time, the user does not need to press the pressing piece, but only needs to rotate the rotating piece to tighten the tightness of the wearable device, so that the operation is more quick and convenient. If the moving piece 200 moves away from the shell 100, the second limiting surface 222 of the limiting groove 220 and the first limiting surface 422 will abut against each other, so that the limiting groove 220 and the limiting block 420 are clamped, and the movement of the moving piece 200 is limited.
