[0035] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0036] A watch is a portable time display device worn on the wrist, mainly composed of a watch body and a watch strap. In daily use, people often combine the watch body with different styles of watch straps to make the watch present different styles. In order to meet people's needs for changing watch straps, watch straps are usually designed to be detachable. However, in the actual research and development and production process, researchers found that traditional watches mainly use spring ears to connect the watch strap to the watch body, which makes the disassembly and assembly process of the watch strap cumbersome and increases the difficulty of disassembly and assembly of the watch strap.

[0037] It should be noted that the spring ear is a connecting component used to connect the watch strap and the watch body, and is mainly composed of a sleeve, a spring inserted in the sleeve and spring ear heads arranged at both ends of the spring. Correspondingly, a mounting groove is provided on the watch body, ear holes are provided on the two opposite side walls of the mounting groove, and a mounting hole is provided at the end of the watch strap; when installing, it is necessary to insert the spring ear into the mounting hole of the watch strap, and then align one of the spring ear heads with one of the ear holes on the watch body, and then press the other spring ear head, and place the spring ear in the mounting groove, and finally release the spring ear and slightly adjust it; when disassembling, it is necessary to use a special tool to insert the gap between the watch strap and the watch body along the width direction of the watch strap, and move the corresponding spring ear head to make it detach from the corresponding ear hole.

[0038] The present invention provides a wrist-worn device, aiming to solve the technical problem that the disassembly and assembly process of a wristwatch strap is complicated and difficult.

[0039] See also Figures 1 to 3 In one embodiment of the present invention, the wrist-worn device includes a main body 100, a wristband 200 and a locking assembly 300. The main body 100 is provided with a receiving groove 110, the wristband 200 is provided in the receiving groove 110, and the wristband 200 is provided with a locking space 210. The locking assembly 300 includes a locking tongue 310; the locking tongue 310 can move along the thickness direction of the main body 100 to be inserted into the receiving groove 110 and accommodated in the locking space 210 to lock the position of the wristband 200. The thickness direction of the main body 100 is as follows: Figure 1 As shown in Z.

[0040] The technical solution of the present invention can simplify the disassembly and assembly process of the wristband 200 and reduce the difficulty of disassembly and assembly of the wristband 200 by providing a locking tongue 310 that can move along the thickness direction of the main body 100 to lock the position of the wristband 200 or release the position lock of the wristband 200; accordingly, when the wrist-worn device is a watch, the disassembly and assembly process of the watch strap can be simplified and the difficulty of disassembly and assembly can be reduced. In this embodiment, the wristband 200 is used to fix the main body 100 on the wrist to realize the wearing of the watch. The locking tongue 310 can move along the thickness direction of the main body 100 to insert or disengage from the locking space 210, lock the position of the wristband 200 or release the position lock of the wristband 200. Specifically, when installing the wristband 200, the user only needs to insert the end of the wristband 200 into the accommodating groove 110, and then drive the locking tongue 310 to move along the thickness direction of the main body 100, so that the locking tongue 310 is inserted into the locking space 210, and the position of the wristband 200 can be locked, thereby realizing the connection between the wristband 200 and the main body 100; and when removing the wristband 200, the user only needs to drive the locking tongue 310 to move, so that the locking tongue 310 is disengaged from the locking space 210, and the position lock of the wristband 200 can be released, and then the wristband 200 can be pulled out of the accommodating groove 110, so that the wristband 200 can be removed from the main body 100. The wrist-worn device is provided with a locking tongue 310 that can move along the thickness direction of the main body 100, so that when the user disassembles the wristband 200, he only needs to drive the locking tongue 310 to move along the thickness direction of the main body 100 to achieve the disassembly and assembly of the wristband 200, which can simplify the disassembly and assembly process of the wristband 200 and reduce the difficulty of disassembly and assembly of the wristband 200.

[0041] It should be noted that the locking assembly 300 has a variety of structures, including but not limited to the following two: 1. The locking assembly 300 also includes at least one lever, which is arranged at the end of the locking tongue 310 and extends out of the main body 100 along the width direction of the wristband 200, and the lever and the locking tongue 310 are stacked along the thickness direction of the main body 100; 2. The locking assembly 300 also includes the following base 320 and pressing block 330, the base 320 is slidably arranged on the main body 100 along the thickness direction of the main body 100, the locking tongue 310 and the pressing block 330 are both arranged on the base 320, and the pressing block 330 is exposed to the outer surface of the main body 100. In the first structure, the user can drive the lock tongue 310 to move along the thickness direction of the main body 100 by pushing the lever along the thickness direction of the main body 100 to lock the position of the wristband 200 or release the position lock of the wristband 200; in the second structure, the user can drive the lock tongue 310 to move along the thickness direction of the main body 100 by pressing and pulling the pressing block 330 to lock the position of the wristband 200 or release the position lock of the wristband 200.

[0042] See also Figure 2 and Figure 3In one embodiment of the present invention, the locking assembly 300 further includes the above-mentioned base 320 and the pressing block 330. The base 320 is slidably disposed on the main body 100 along the thickness direction of the main body 100. The locking tongue 310 and the pressing block 330 are both disposed on the side of the base 320 facing the receiving groove 110. The pressing block 330 is exposed to the outer surface of the main body 100. The pressing block 330 can drive the base 320 to move along the thickness direction of the main body 100, thereby driving the locking tongue 310 to move along the thickness direction of the main body 100. Specifically, when disassembling the wristband 200, the user only needs to press or pull the pressing block 330 to drive the base 320 to move along the thickness direction of the main body 100, and drive the locking tongue 310 to move along the thickness direction of the main body 100, thereby inserting or disengaging the locking tongue 310 into or out of the locking space 210, locking the position of the wristband 200 or releasing the position lock of the wristband 200, thereby realizing the disassembly of the wristband 200. That is, the user only needs to press or pull the pressing block 330 to realize the disassembly and assembly of the wristband 200, which can simplify the disassembly and assembly process of the wristband 200 and reduce the difficulty of disassembly and assembly of the wristband 200. In a specific embodiment, the pressing block 330 is exposed to the end surface of the main body 100.

[0043] See also Figure 2 In one embodiment of the present invention, the pressing block 330 is disposed on the locking tongue 310, and the end of the locking tongue 310 is disposed on one side of the pressing block 330 along the width direction of the wristband 200. The wristband 200 is provided with a locking groove 211 extending along the width direction of the wristband 200 and an escape notch 220 connected to the locking groove 211. The pressing block 330 is accommodated in the escape notch 220, and the locking space 210 includes the locking groove 211. Figure 1As shown by Y in FIG. In the present embodiment, the pressing block 330 is directly mounted on the locking tongue 310, so that the structure of the wrist-worn device can be made more compact. The avoidance notch 220 provided on the wristband 200 is used to accommodate the pressing block 330, so as to avoid interference between the wristband 200 and the pressing block 330, and to ensure that the wristband 200 can be inserted into the receiving groove 110. The end of the locking tongue 310 is extended out of the pressing block 330 along the width direction of the wristband 200, so as to ensure that after the wristband 200 is inserted into the receiving groove 110, the locking tongue 310 can move along the thickness direction of the main body 100, so as to be inserted into or out of the locking space 210, lock the position of the wristband 200 or release the position lock of the wristband 200. Specifically, when the wristband 200 is inserted into the receiving groove 110, the pressing block 330 is received in the avoidance notch 220, and as the wristband 200 continues to be inserted, the pressing block 330 will slide in the avoidance notch 220, and the locking groove 211 will correspond to the end of the locking tongue 310. At this time, the user pulls the pressing block 330 to drive the locking tongue 310 to move along the thickness direction of the main body 100, so that the end of the locking tongue 310 is inserted into the locking groove 211, thereby locking the position of the wristband 200. It should be noted that in the wristband 200 device, the pressing block 330 can be partially installed on the locking tongue 310, or it can be completely installed on the locking tongue 310. In this embodiment, the part of the pressing block 330 close to the receiving groove 110 is installed on the locking tongue 310.

[0044] In a specific embodiment, the locking tongue 310 and the locking groove 211 are both hook-shaped structures, specifically, the side of the locking tongue 310 away from the opening of the accommodating groove 110 is an inclined surface, and the side wall of the locking groove 211 near the end of the wristband 200 is an inclined surface. The design of the hook-shaped structure can hook the wristband 200 after the wristband 200 is installed on the main body 100, reducing the risk of the wristband 200 being detached.

[0045] See also Figure 3In one embodiment of the present invention, the two ends of the locking tongue 310 are respectively arranged on both sides of the pressing block 330 along the width direction of the wristband 200, the number of the locking grooves 211 is two, and the two locking grooves 211 are arranged oppositely along the width direction of the wristband 200; the two ends of the locking tongue 310 can be inserted into the receiving groove 110 and accommodated in the corresponding locking grooves 211 to lock the position of the wristband 200. Specifically, when the wristband 200 is inserted into the receiving groove 110, the two ends of the locking tongue 310 will correspond to the two oppositely arranged locking grooves 211 one by one. At this time, the user pulls the pressing block 330 to drive the locking tongue 310 to move along the thickness direction of the main body 100, so that the two ends of the locking tongue 310 are inserted into the corresponding locking grooves 211, and the position of the wristband 200 can be locked. In the present embodiment, the two locking grooves 211 are both connected to the avoidance notch 220 to form a T-shaped groove; that is, in order to cooperate with the locking assembly 300 installed on the main body 100 to achieve the locking of the wristband 200, only a T-shaped groove needs to be opened on the wristband 200, and there are connecting parts on both sides of the T-shaped groove along the width direction of the wristband 200. In this way, the structural strength of the wristband 200 can be ensured and the risk of damage to the wristband 200 during use can be reduced.

[0046] See also Figure 5 In another embodiment of the present invention, the number of the locking tongues 310 and the locking grooves 211 are both two, and the two locking tongues 310 are arranged at intervals along the width direction of the wristband 200. The pressing block 330 is provided with an escape space 331. The ends of the two locking tongues 310 facing each other are arranged corresponding to the escape space 331, and the two locking grooves 211 are arranged opposite to each other along the width direction of the wristband 200; the ends of the two locking tongues 310 facing each other can be inserted into the accommodating groove 110 and accommodated in the corresponding locking groove 211 to lock the position of the wristband 200. In this embodiment, the ends of the two locking tongues 310 facing each other are arranged corresponding to the escape space 331, that is, the ends of the two locking tongues 310 facing each other extend out of the pressing block 330 along the width direction of the wristband 200. Specifically, when the wristband 200 is inserted into the receiving groove 110, the ends of the two locking tongues 310 facing each other correspond to the two locking grooves 211 disposed opposite to each other. At this time, the user pulls the pressing block 330 to drive the locking tongue 310 to move along the thickness direction of the main body 100, so that the ends of the two locking tongues 310 facing each other are inserted into the corresponding locking grooves 211, thereby locking the position of the wristband 200. In this embodiment, the pressing block 330 is U-shaped, and the notch opened by the U-shape is the avoidance space 331. The closed end of the pressing block 330 is exposed to the outer surface of the main body 100, and the open end of the pressing block 330 is disposed on the locking tongue 310.

[0047] See also Figures 6 to 8In another embodiment of the present invention, the locking tongue 310 and the pressing block 330 are spaced apart along the depth direction of the receiving groove 110, the wristband 200 is provided with a locking groove 211, and the locking space 210 includes the locking groove 211; the locking tongue 310 can be inserted into the receiving groove 110 and accommodated in the locking groove 211 to lock the position of the wristband 200. Figure 1 Specifically, when the wristband 200 is inserted into the receiving groove 110, the locking tongue 310 will correspond to the locking groove 211. At this time, the user pulls the locking tongue 310 to drive the locking tongue 310 to move along the thickness direction of the main body 100, so that the locking tongue 310 is inserted into the locking groove 211, and the position of the wristband 200 can be locked. In this embodiment, when the locking tongue 310 is in the position of locking the wristband 200, the locking tongue 310 is completely inserted into the locking groove 211, which can better lock the position of the wristband 200 and make the wristband 200 more securely installed.

[0048] See also Figure 3 In one embodiment of the present invention, the end surface of the pressing block 330 facing away from the base 320 is flush with the outer surface of the main body 100. Specifically, when the user wears the wrist-worn device, it is very easy to squeeze the pressing block 330 and drive the locking tongue 310 to disengage from the receiving groove 110. By making the end surface of the pressing block 330 facing away from the base 320 flush with the outer surface of the main body 100, it is possible to prevent the user from pressing the pressing block 330 when wearing the wrist-worn device, thereby reducing the risk of the wristband 200 falling off.

[0049] In one embodiment of the present invention, the main body 100 is provided with a recessed cavity 120, and the end surface of the pressing block 330 facing away from the base 320 is flush with the bottom surface of the recessed cavity 120. The wrist-worn device further comprises a cover plate 121, which is movably provided at one side of the recessed cavity 120, and the cover plate 121 can be moved to the recessed cavity 120 and abut against the end surface of the pressing block 330 facing away from the base 320. After using the wrist-worn device, the user usually puts the wrist-worn device into a storage bag or a storage box. However, the storage bag or the storage box often also puts other items with sharp parts. After the wrist-worn device is put in, the sharp parts of the other items are very likely to abut against the pressing block 330 and squeeze the pressing block 330, causing the locking tongue 310 to disengage from the locking groove 211, thereby causing the wristband 200 to disengage from the main body 100. In this embodiment, by providing a movable cover plate 121 on one side of the recessed cavity 120, the user can drive the cover plate 121 to move into the recessed cavity 120 when storing a wrist-worn device such as a watch, so as to cover the pressing block 330, reduce the possibility of the sharp part of other objects squeezing the pressing block 330, and further reduce the possibility of the wristband 200 being separated from the main body 100 when the wrist-worn device is stored. In a specific embodiment, one side of the cover plate 121 is rotatably provided on the side of the edge of the recessed cavity 120 away from the main body 100 through a rotating shaft, and the other side of the cover plate 121 is provided with a toggle portion 122 for user operation, and the toggle portion 122 is a groove or a toggle block. In another specific embodiment, the cover plate 121 is slidably provided on the main body 100 and can slide into the recessed cavity 120, and the cover plate 121 is provided with a toggle portion 122 for user operation, and the toggle portion 122 is a toggle block provided on the cover plate 121.

[0050] Please refer to the figure Figure 8 In another embodiment of the present invention, the pressing block 330 extends out of the outer surface of the main body 100, and a limiting groove 311 is provided on the side of the lock tongue 310 away from the opening of the accommodating groove 110, and a limiting block 212 is provided on the inner wall of the locking space 210; the limiting block 212 can be inserted into the limiting groove 311 to lock the position of the lock tongue 310. Specifically, when the wristband 200 is inserted into the accommodating groove 110 and the locking tongue 310 is inserted into the locking groove 211, the limiting block 212 is arranged corresponding to the limiting groove 311. By slightly pulling the wristband 200 in the opposite direction of the insertion direction of the wristband 200, the limiting block 212 can be inserted into the limiting groove 311 to lock the position of the locking tongue 310 in the thickness direction of the main body 100. In this case, even if the pressing block 330 of the wrist-worn device is squeezed, it is impossible to drive the pressing block 330 to move, and then drive the locking tongue 310 to move. Therefore, the risk of the locking tongue 310 falling off from the locking groove 211 can be reduced, thereby reducing the risk of the wristband 200 falling off.
