[0006] The embodiments of the present application also provide a wearable device comprising the above-mentioned watchband connection structure.

[0007] The watchband connecting structure and wearable device provided by the embodiments of the present application are provided with a head grain in the accommodating cavity of the watchband, and the head grain comprises a limiting portion which can be elastically deformed and displaced in the accommodating cavity. The watch ear and the button on the watch case can be inserted into the accommodating cavity of the watchband and can be inserted into the buckling position in the accommodating cavity. The watch ear extrudes the limiting portion when entering the accommodating cavity to cause the limiting portion to be displaced, and the limiting portion is buckled when entering the buckling position in the accommodating cavity, thereby realizing the connection between the watchband and the watch case. When the watchband is disassembled, the button only needs to be pressed to cause the button to be displaced and drive the limiting portion to be displaced, and then the limiting portion is buckled with the watch ear, so that the watch ear can be disassembled from the watch case. Therefore, when the watchband is disassembled and assembled, no special tool is needed, and the disassembly and assembly operation is simple, which is beneficial to improving the user experience.

[0008] In some embodiments, the limiting portion is a cantilever provided on the main body portion, the watchband is provided with a first opening which is communicated with the accommodating cavity to expose the button, the main body portion is provided with a through hole facing the first opening, and the limiting portion extends from the edge of the through hole into the through hole.

[0026] To make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below with reference to the drawings. However, those skilled in the art can understand that, in the embodiments of the present application, many technical details are presented in order to make the readers better understand the present application. However, the technical solutions claimed by the present application can be implemented even without these technical details and various changes and modifications based on the following embodiments. The division of the following embodiments is for the convenience of description and should not constitute any limitation on the specific embodiments of the present application. The embodiments can be combined and referenced with each other without contradiction.

[0027] With the continuous development of intelligent technology, wearable devices such as wristbands and watches can not only display time, but also can be used in cooperation with mobile phones to realize diversified functions such as calling and vital sign monitoring. This makes the use scenarios of wearable devices more and more rich. Users can not only display time by wearing wearable devices in a leisure state, but also can realize vital sign monitoring by wearing wearable devices in a motion or sleep state.

[0028] The display body of the wearable device is usually fixed on the wrist of the user through the watch band. In some cases, the watch band of the wearable device is connected with the display body in the form of a lug bar. In this way, when the user needs to replace or repair the watch band of the wearable device, the lug bar needs to be disassembled by using a special tool to detach the watch band of the wearable device from the display body, and then the lug bar is reinstalled to realize the connection between the watch band and the display body. The disassembly and assembly operation is complicated, which is not conducive to improving the user experience.

[0029] In order to facilitate the user to disassemble and assemble the watch band of the wearable device, some embodiments of the present application provide a watch band connection structure. The watch band is matched with the watch case of the display body through a limiting structure. When the user installs the watch band, the user only needs to push the watch lug provided on the watch case into the watch band and make the watch lug buckled with the head grain in the watch band to realize the connection between the watch band and the watch case. When the user disassembles the watch band, the user only needs to press the button provided on the watch case to make the watch lug and the head grain in the watch band exit the buckling. In this way, the user can complete the disassembly and assembly of the watch band without using a special tool, and the disassembly and assembly operation is simple, which can be conducive to improving the user experience.

[0030] The watch band connection structure provided by some embodiments of the present application will be described below with reference to the drawings. Figures 1 to 8 The watch band connection structure provided by some embodiments of the present application will be described below with reference to the drawings.

[0031] As shown in FIG. 1, the watch band connection structure provided by some embodiments of the present application includes a watch case 1 and a watch band 2. Figures 1 to 8As shown, the watchband connecting structure provided by some embodiments of the present application includes a watchband 10, a head grain 20, and a watch case 30. The watchband 10 is provided with a receiving cavity 11. The head grain 20 is arranged in the receiving cavity 11 of the watchband 10. The head grain 20 includes a main body part 21 connected with the inner wall of the receiving cavity 11, and a limiting part 22 connected with the main body part 21 and capable of being elastically deformed and displaced in the receiving cavity 11. The watch case 30 is provided with a lug 31 and an elastically pressable button 32. The lug 31 and the button 32 can be inserted into the receiving cavity 11 and reach a buckling position in the receiving cavity 11. When the lug 31 enters the receiving cavity 11, the lug 31 extrudes the limiting part 22 to make the limiting part 22 displace. When the lug 31 moves to the buckling position in the receiving cavity 11, the lug 31 buckles with the reset limiting part 22. When the button 32 moves to the buckling position in the receiving cavity 11, the button 32 abuts against the limiting part 22 and exposes the watchband 10. When the button 32 is pressed, the button 32 is displaced to make the lug 31 and the limiting part 22 unbuckle.

[0032] The watchband 10 is a component for fixing a wearable position on the wrist of a user in a wearable device. The watchband 10 is usually two. One end of the two watchbands 10 is connected to opposite sides of the watch case 30. The other end of the two watchbands 10 is a free end. The free ends of the two watchbands 10 can be buckled together by a buckle to be fixed on the wrist of the user. The material of the watchband 10 can be a flexible material or a metal material. The watchband 10 can be made by one-piece molding or weaving.

[0033] The head grain 20 is a component for connecting the watchband 10 and the watch case 30 in a wearable device. The head grain 20 can be formed in the receiving cavity 11 of the watchband 10 by an in-mold injection process. The main body part 21 is a part of the head grain 20 connected with the inner wall of the receiving cavity 11 of the watchband 10, so that the head grain 20 can be fixed in the receiving cavity 11 of the watchband 10. The limiting part 22 is a part of the head grain 20 buckled with the lug 31 on the watch case 30. The limiting part 22 can be elastically displaced relative to the main body part 21 in the receiving cavity 11 of the watchband 10.

[0034] The watch case 30 is a shell of a display main body in a wearable device. The watch case 30 can protect key components in the display main body. The outer contour of the watch case 30 can be rectangular or circular. The watch case 30 can be made of a metal material or a plastic material. The lug 31 and the button 32 can be integrally formed on the watch case 30. The lug 31 buckles with the limiting part 22 of the head grain 20 to connect with the watchband 10. The buckling between the lug 31 and the limiting part 22 of the head grain 20 can be achieved by a convex groove cooperation structure or a stepped cooperation structure. The button 32 can be displaced when pressed from outside to drive the limiting part 22 of the head grain 20 to make the lug 31 and the limiting part 22 of the head grain 20 unbuckle, thereby achieving the disassembly of the watchband 10.

[0035] The watchband connecting structure provided by some embodiments of the present application is provided with a head grain 20 in the accommodating cavity 11 of the watchband 10, and the head grain 20 comprises a limiting portion 22 which can be elastically deformed and displaced in the accommodating cavity 11. The watch ear 31 and the button 32 on the watch case 30 can be inserted into the accommodating cavity 11 of the watchband 10 and can be inserted to the buckling position in the accommodating cavity 11. When the watch ear 31 enters the accommodating cavity 11, the limiting portion 22 is pressed and displaced, and when the watch ear 31 enters the buckling position in the accommodating cavity 11, the limiting portion 22 is buckled with the reset limiting portion 22, so as to realize the connection between the watchband 10 and the watch case 30. When the watchband 10 is disassembled, the button 32 is only pressed to displace the button 32 and drive the limiting portion 22 to displace, so as to make the limiting portion 22 and the watch ear 31 exit from the buckling, and then the watch ear 31 can be disassembled from the watch case 30. Therefore, when the watchband 10 is disassembled and assembled, no special tool is needed, and the disassembly and assembly operation is simple, which is beneficial to improve the use experience of the user.

[0036] In some embodiments of the present application, the limiting portion 22 can be a cantilever provided on the main body portion 21, the watchband 10 is provided with a first opening 12 which is communicated with the accommodating cavity 11 to expose the button 32, the main body portion 21 is provided with a through hole 211 which faces the first opening 12, and the limiting portion 22 extends from the edge of the through hole 211 into the through hole 211.

[0037] The limiting portion 22 is a cantilever provided on the main body portion 21, that is, one end of the limiting portion 22 is a fixed end, the fixed end is connected with the main body portion 21, and the other end of the limiting portion 22 is a free end. When the limiting portion 22 adopts the cantilever structure, the free end of the limiting portion 22 can rotate relative to the fixed end to a certain extent, and automatically resets to the initial state after the external force disappears.

[0038] As shown in Figure 1 , the overall outer contour of the main body portion 21 presents a quadrilateral structure, the through hole 211 is arranged at the middle position of the main body portion 21, and the limiting portion 22 is located in the through hole 211. At the same time, the opposite sides of the main body portion 21 near the edge of the watchband 10 are arc-shaped and curved, and are arranged between the opposite two inner walls of the accommodating cavity 11, so that the position of the head grain 20 in the accommodating cavity 11 can be kept fixed, and the disengagement can be avoided.

[0039] By adopting the cantilever structure shown in Figure 1 , the limiting portion 22 can be elastically deformed and displaced relative to the main body portion 21 in the accommodating cavity 11 of the watchband 10, and the part near the periphery of the main body portion 21 can be connected with the inner wall of the accommodating cavity 11 of the watchband 10, so as to ensure the connection stability between the main body portion 21 and the watchband 10.

[0040] In other embodiments, the limiting portion 22 can be connected to the main portion 21 by a spring, a spring sheet or other elastic element, so that the limiting portion 22 can be elastically displaced relative to the main portion 21 within the accommodating cavity 11 of the watchband 10. Alternatively, the limiting portion 22 can be made of elastic material, which can also be elastically deformed when subjected to external force. When the main portion 21 is stably connected within the accommodating cavity 11 of the watchband 10, the limiting portion 22 can be arranged at the edge of the main portion 21.

[0041] In addition, the limiting portion 22 can include a main portion 221 protruding from the main portion 21 towards the watchcase 30 and a clamping portion 222 protruding from the main portion 221 towards the first opening 12, which is displaced when the watch lug 31 enters the accommodating cavity 11 to allow the watch lug 31 to enter the clamping position within the accommodating cavity 11.

[0042] The main portion 221 is the portion of the limiting portion 22 connected to the main portion 21, and the clamping portion 222 is the portion of the limiting portion 22 that functions as a clamping action. The main portion 221 can protrude from the main portion 21 towards the watchcase 30 or away from the watchcase 30.

[0043] The clamping portion 222 is displaced when the watch lug 31 enters the accommodating cavity 11 of the watchband 10, so as not to block the movement of the watch lug 31 to the clamping position within the accommodating cavity 11. When the watch lug 31 reaches the clamping position within the accommodating cavity 11 without being blocked, the clamping portion 222 is no longer subjected to the pressing force from the watch lug 31, and the clamping portion 222 returns to its original position. At this time, the clamping portion 222 is clamped with the watch lug 31, i.e. is blocked in the movement path of the watch lug 31, so that the watch lug 31 cannot automatically exit the accommodating cavity 11. Thus, the clamping action of the watch lug 31 and the limiting portion 22 is achieved.

[0044] As shown in Figure 2 The watch lug 31 is arranged around the watchcase 30 to form a hollow area 301 corresponding to the through hole 211, and the button 32 is a cantilever arranged on the watchcase 30 and located within the hollow area 301.

[0045] The lug 31 includes two extensions 311 extending from the edge of the case 30 and a fastening portion 312 connecting the ends of the two extensions 311. A hollow area 301 is formed between the fastening portion 312 of the lug 31, the two extensions 311, and the edge of the case 30, corresponding to the through hole 211. During the process of the lug 31 entering the fastening position in the receiving cavity 11, the two extensions 311 of the lug 31 can act as guides, while the fastening portion 312 of the lug 31 will press the limiting portion 22 of the head link 20, causing the limiting portion 22 to move out of the movement path of the lug 31. When the lug 31 reaches the fastening position in the receiving cavity 11, the latching portion 222 of the limiting portion 22 also enters the hollow area 301. At this time, the squeezing force from the lug 31 on the latching portion 222 of the limiting portion 22 disappears, and the limiting portion 22 returns to its original position. After the limiting part 22 is reset, it is locked in the hollow area 301, that is, locked in the moving path of the fastening part 312 of the lug 31, thereby fastening with the lug 31.

[0046] Button 32 is a cantilever mounted on the watch case 30. By adopting a cantilever structure, button 32 can rotate relative to the watch case 30 when pressed, and automatically reset after the pressing action is removed.

[0047] By placing the button 32 within the hollow area 301 formed by the lug 31 surrounding the watch case 30, it is advantageous that the position of the button 32 is directly aligned with the position of the limiting part 22 of the head link 20, thereby making it easier for the user to press the button 32 to make the limiting part 22 of the head link 20 exit the movement path of the lug 31.

[0048] Additionally, the button 32 may include a connecting portion 321 connected to the case 30 and a boss 322 protruding from the connecting portion 321 away from the first opening 12, the boss 322 abutting against the limiting portion 22 of the headstock 20.

[0049] Connecting part 321 is the part of button 32 that connects to the watch case 30, such as Figure 2 As shown, the width of the end of the connecting portion 321 away from the case 30 can be increased to provide sufficient space for the boss 322. The boss 322 is the part of the button 32 that abuts against the limiting part 22 of the lead-in 20. By adopting the form of the boss 322, it is easier to achieve the abutment between the button 32 and the limiting part 22. At the same time, sufficient movement space is reserved between the connecting portion 321 and the lead-in 20 so that the button 32 can move when it is pressed, thereby causing the limiting part 22 to move.

[0050] In some embodiments, the abutting surface of the boss 322 abutting against the limiting portion 22 can be stepped, and the stepped abutting surface comprises a first contact surface 3221 and a second contact surface 3222 abutting against the limiting portion 22, and a transition surface 3223 connecting the first contact surface 3221 and the second contact surface 3222, the second contact surface 3222 is closer to the watch case 30 than the first contact surface 3221, and the protruding height of the second contact surface 3222 from the connecting portion 321 is greater than the protruding height of the first contact surface 3221 from the connecting portion 321.

[0051] By setting the abutting surface of the boss 322 abutting against the limiting portion 22 as stepped, the limiting effect can be achieved during the movement of the watch lug 31 and the button 32 to the buckling position in the accommodating cavity 11. That is, when the watch lug 31 and the button 32 move to the buckling position in the accommodating cavity 11, because the boss 322 has a stepped surface, and the protruding height of the second contact surface 3222 from the connecting portion 321 is greater than the protruding height of the first contact surface 3221 from the connecting portion 321, the continued movement of the watch lug 31 and the button 32 in the accommodating cavity 11 can be limited to a certain extent, and the positioning of the watch lug 31 and the button 32 is facilitated.

[0052] When the watch lug 31 and the button 32 move to the buckling position in the accommodating cavity 11, the second contact surface 3222 closer to the watch case 30 abuts against the main body portion 221 of the limiting portion 22, and the first contact surface 3221 abuts against the buckle portion 222 of the limiting portion 22. Thus, the continued movement of the watch lug 31 and the button 32 is limited to a certain extent.

[0053] In addition, the button 32 can further comprise a pressing portion 323 protruding from the connecting portion 321 towards the first opening 12, and the pressing portion 323 is exposed from the first opening 12 and protrudes from the watchband 10.

[0054] By making the pressing portion 323 protrude from the watchband 10, the user can conveniently apply a pressing force to the pressing portion 323, so that the button 32 as a whole is displaced to drive the limiting portion 22 of the head grain 20 to be displaced, so as to disassemble the watchband 10.

[0055] In some embodiments, the first opening 12 is located on the side of the watchband 10 attached to the wrist.

[0056] By setting the first opening 12 on the side of the watchband 10 attached to the wrist, the separation of the watchband 10 from the watch case 30 caused by accidental touch can be avoided.

[0057] In addition, the watchband 10 can be made of a flexible material, and the limiting portion 22 abuts against the inner wall of the accommodating cavity 11.

[0058] In some embodiments, the watch strap 10 may be made of soft rubber, and the headlink 20 may be made of hard rubber. During the process of the lugs 31 and buttons 32 moving to the fastening position within the receiving cavity 11, the lugs 31 press against the limiting portion 22 of the headlink 20, causing the limiting portion 22 to shift. Simultaneously, the shift of the limiting portion 22 compresses the portion of the watch strap 10 that abuts against the limiting portion 22. Thus, after the compressive force from the lugs 31 on the limiting portion 22 of the headlink 20 disappears, the limiting portion 22 can reset under its own restoring force and the restoring force of the compressed portion of the watch strap 10, thereby facilitating the rapid reset of the limiting portion 22.

[0059] The watch strap connection structure provided in some embodiments of this application has the following usage methods:

[0060] Assemble the watch case 30 and the watch strap 10 in a direction that brings them closer together. Assemble the lugs 31 and pushers 32 located on the watch case 30 along... Figure 9 The watch is inserted into the second opening 13 of the receiving cavity 11 in the direction indicated by the middle arrow X, closer to the strap 10. During insertion, the lug 31 presses against the limiting part 22 of the headpiece 20, causing the limiting part 22 to exit the movement path of the lug 31. When the lug 31 moves to the engaging position within the receiving cavity 11, the pressing force on the limiting part 22 of the headpiece 20 from the lug 31 disappears, the limiting part 22 of the headpiece 20 resets, and the limiting part 22 of the headpiece 20 re-enters the movement path of the lug 31. This engages with the lug 31, preventing the limiting part 22 of the headpiece 20 from automatically exiting the receiving cavity 11. At this time, the button 32 abuts against the limiting part 22 of the headpiece 20 and is exposed from the first opening 12.

[0061] When it is necessary to remove the watch strap 10, a pressing force is applied to the button 32, causing the button 32 to shift and thus causing the limiting part 22 of the lug 20 to shift, so that the limiting part 22 of the lug 20 exits the moving path of the lug 31. At this time, by moving the watch case 30 away from the watch strap 10, the watch case 30 and the watch strap 10 can be separated, thus completing the removal of the watch strap 10.

[0062] Some embodiments of this application also provide a wearable device, which includes the watch strap connection structure described in the above embodiments.

[0063] By adopting the watchband connection structure in the above embodiments, the wearable device can be easily attached and detached from the watchband 10 without the need for specific tools. Users can independently complete the attachment and detachment without any training, which improves the user experience. Simultaneously, the lug 20 can be integrally molded within the receiving cavity 11 of the watchband 10, and the lugs 31 and buttons 32 can be integrally molded onto the watch case 30, thereby reducing the adverse impact on the overall structural yield caused by using multiple detachable components.

[0064] Those skilled in the art can understand that the above-mentioned embodiments are specific examples for implementing the present application, and in actual applications, various changes can be made in form and details without departing from the spirit and scope of the present application.
