[0036] A wristwatch is a portable time display device worn on the wrist, mainly composed of two parts: the watch case and the watch strap. In daily use, people often combine the watch case with different styles of watch straps to create various looks. To meet the need for changing watch straps, they are usually designed as detachable structures. However, in actual research and development and production, researchers have found that traditional wristwatches mainly use spring bars to connect the strap to the watch case, which makes the process of assembling and disassembling the strap cumbersome and increases the difficulty of doing so.

[0037] It should be noted that spring bars are connecting components used to connect the watch strap and the watch case. They mainly consist of a sleeve, a spring passing through the sleeve, and spring bar tips at both ends of the spring. Correspondingly, the watch case has a mounting groove, and ear holes are provided on the two opposite side walls of the mounting groove. The end of the watch strap has a mounting hole. During installation, the spring bar needs to be inserted into the mounting hole of the watch strap, then one spring bar tip is aligned with one of the ear holes on the watch case. Next, press the other spring bar tip and place the spring bar into the mounting groove. Finally, release the spring bar and make slight adjustments. During disassembly, a special tool is needed to insert into the gap between the watch strap and the watch case along the width direction of the watch strap, and to move the corresponding spring bar tip to disengage it from the corresponding ear hole.

[0038] This invention proposes a wrist-wearing device to solve the technical problems of complex and difficult watch strap assembly and disassembly processes.

[0039] Please see 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 disposed 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 is movable along the thickness direction of the main body 100 to insert into the receiving groove 110 and be received in the locking space 210, thereby locking the position of the wristband 200. The thickness direction of the main body 100 is as follows: Figure 1 As shown in Z in the diagram.

[0040] The technical solution of this invention, by providing a locking tongue 310 that can move along the thickness direction of the main body 100 to lock or release the position of the wristband 200, simplifies the process of assembling and disassembling the wristband 200 and reduces the difficulty of doing so. Correspondingly, when the wrist-wearing device is a wristwatch, the process of assembling and disassembling the wristwatch strap can be simplified, reducing the difficulty of assembly and disassembly. In this embodiment, the wristband 200 is used to fix the main body 100 on the wrist, enabling the wearing of a wristwatch. The locking tongue 310 can move along the thickness direction of the main body 100 to insert into or disengage from the locking space 210, locking or releasing the position of the wristband 200. Specifically, when installing the wristband 200, the user only needs to insert the end of the wristband 200 into the receiving 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, thereby locking the position of the wristband 200 and connecting the wristband 200 to the main body 100. 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, thereby releasing the position lock of the wristband 200. Then, the wristband 200 can be pulled out from the receiving groove 110, thereby removing the wristband 200 from the main body 100. The wristband device is equipped with a locking tongue 310 that can move along the thickness direction of the main body 100. This allows the user to assemble or disassemble the wristband 200 simply by driving the locking tongue 310 to move along the thickness direction of the main body 100. This simplifies the assembly and disassembly process of the wristband 200 and reduces the difficulty of assembling or disassembling the wristband 200.

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

[0042] Please see Figure 2 and Figure 3In one embodiment of the present invention, the locking assembly 300 further includes the aforementioned base 320 and pressing block 330. The base 320 is slidably disposed on the body 100 along the thickness direction of the 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, and the pressing block 330 is exposed on the outer surface of the body 100. The pressing block 330 can drive the base 320 to move along the thickness direction of the body 100, thereby driving the locking tongue 310 to move along the thickness direction of the body 100. Specifically, when assembling or 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 body 100 and drive the locking tongue 310 to move along the thickness direction of the body 100, thereby causing the locking tongue 310 to insert into or disengage from the locking space 210, locking the position of the wristband 200 or releasing the position lock of the wristband 200, thus realizing the assembly or disassembly of the wristband 200. In other words, users can assemble or disassemble the wristband 200 simply by pressing or pulling the pressing block 330, which simplifies the assembly and disassembly process and reduces the difficulty of assembling or disassembling the wristband 200. In a specific embodiment, the pressing block 330 is exposed on the end face of the main body 100.

[0043] Please see Figure 2 In one embodiment of the present invention, a pressing block 330 is disposed on a 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 a clearance notch 220 communicating with the locking groove 211. The pressing block 330 is accommodated in the clearance notch 220, and the locking space 210 includes the locking groove 211. The width direction of the wristband 200 is as follows... Figure 1As shown in the Y diagram. In this embodiment, the pressing block 330 is directly mounted on the locking tongue 310, which makes the structure of the wristband device more compact. The clearance notch 220 on the wristband 200 is used to accommodate the pressing block 330 to avoid interference between the wristband 200 and the pressing block 330, ensuring that the wristband 200 can be inserted into the receiving groove 110. The end of the locking tongue 310 extends out of the pressing block 330 along the width direction of the wristband 200. This is 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 to insert into or disengage from the locking space 210, locking the position of the wristband 200 or releasing the position lock of the wristband 200. Specifically, when the wristband 200 is inserted into the receiving groove 110, the pressing block 330 is accommodated in the clearance notch 220. As the wristband 200 continues to be inserted, the pressing block 330 slides in the clearance notch 220, and the locking groove 211 aligns with the end of the latch 310. At this time, the user can pull the pressing block 330 to drive the latch 310 to move along the thickness direction of the main body 100, so that the end of the latch 310 is inserted into the locking groove 211, thereby locking the position of the wristband 200. It should be noted that in this wristband 200 device, the pressing block 330 can be partially or completely installed on the latch 310. In this embodiment, the portion of the pressing block 330 near the receiving groove 110 is installed on the latch 310.

[0044] In one specific embodiment, both the locking tongue 310 and the locking groove 211 are hook-shaped structures. Specifically, the side of the locking tongue 310 facing away from the opening of the receiving groove 110 is inclined, and the side wall of the locking groove 211 near the end of the wristband 200 is inclined. This hook-shaped design allows the wristband 200 to be hooked after it is installed onto the main body 100, reducing the risk of the wristband 200 detaching.

[0045] Please see Figure 3In one embodiment of the present invention, the two ends of the locking tongue 310 are respectively disposed on both sides of the pressing block 330 along the width direction of the wristband 200. There are two locking grooves 211, and the two locking grooves 211 are arranged opposite each other 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 groove 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 one-to-one with the two oppositely arranged locking grooves 211. At this time, the user can pull 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, thereby locking the position of the wristband 200. In this embodiment, both locking grooves 211 are connected to the clearance notch 220 to form a T-shaped groove; that is, in order to cooperate with the locking component 300 installed on the main body 100 to lock 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. Thus, the structural strength of the wristband 200 can be guaranteed and the risk of damage to the wristband 200 during use can be reduced.

[0046] Please see Figure 5 In another embodiment of the present invention, there are two locking tongues 310 and two locking grooves 211. The two locking tongues 310 are spaced apart along the width direction of the wristband 200. The pressing block 330 is provided with a clearance space 331. The mutually facing ends of the two locking tongues 310 are respectively arranged corresponding to the clearance space 331. The two locking grooves 211 are arranged opposite to each other along the width direction of the wristband 200. The mutually facing ends of the two locking tongues 310 can be inserted into the receiving groove 110 and accommodated in the corresponding locking groove 211 to lock the position of the wristband 200. In this embodiment, the mutually facing ends of the two locking tongues 310 are respectively arranged corresponding to the clearance space 331, that is, the mutually facing ends of the two locking tongues 310 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 slot 110, the mutually facing ends of the two locking tongues 310 correspond one-to-one with the two opposite locking slots 211. At this time, the user pulls the pressing block 330 to drive the locking tongues 310 to move along the thickness direction of the main body 100, so that the mutually facing ends of the two locking tongues 310 are inserted into the corresponding locking slots 211, thereby locking the position of the wristband 200. In this embodiment, the pressing block 330 is U-shaped, and the slot opened in the U-shape is the clearance space 331. The closed end of the pressing block 330 is exposed on the outer surface of the main body 100, and the open end of the pressing block 330 is located on the locking tongue 310.

[0047] Please see 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, and the wristband 200 is provided with a locking groove 211, the locking space 210 including 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. The depth direction of the receiving groove 110 is as follows: Figure 1 As shown by X in the diagram. Specifically, when the wristband 200 is inserted into the receiving slot 110, the locking tongue 310 corresponds to the locking slot 211. At this time, the user can pull the locking tongue 310 to drive it to move along the thickness direction of the main body 100, so that the locking tongue 310 is inserted into the locking slot 211, thereby locking the position of the wristband 200. In this embodiment, when locking the position of the wristband 200, the locking tongue 310 is fully inserted into the locking slot 211, which can better lock the position of the wristband 200 and make the wristband 200 more securely installed.

[0048] Please see Figure 3 In one embodiment of the present invention, the end face 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 wristband, it is very easy to press the pressing block 330 and drive the locking tongue 310 to disengage from the receiving groove 110. By making the end face of the pressing block 330 facing away from the base 320 flush with the outer surface of the main body 100, the user can avoid pressing the pressing block 330 when wearing the wristband, 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 face of the pressing block 330 away from the base 320 is flush with the bottom surface of the recessed cavity 120. The wrist-worn device also includes a cover plate 121, which is movably disposed on one side of the recessed cavity 120 and can move to the recessed cavity 120 and abut against the end face of the pressing block 330 away from the base 320. After using the wrist-worn device, the user usually puts it into a storage bag or storage box. However, the storage bag or storage box often contains other items with sharp parts. After the wrist-worn device is put in, the sharp parts of other items are very likely to press against and squeeze the pressing block 330, causing the locking tongue 310 to disengage from the locking groove 211, thereby causing the wristband 200 to detach 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 into the recessed cavity 120 when storing wrist-worn devices such as watches, to cover the pressing block 330, reducing the possibility of sharp parts of other items pressing the pressing block 330, and thus reducing the possibility of the wristband 200 detaching from the main body 100 when the wrist-worn device is stored. In one specific embodiment, one side of the cover plate 121 is rotatably disposed on the side of the recessed cavity 120 away from the edge of the main body 100 via a pivot, and the other side of the cover plate 121 is provided with a toggle part 122 for easy operation by the user. The toggle part 122 is a groove or a toggle block. In another specific embodiment, the cover plate 121 is slidably disposed on the main body 100 and can slide into the recessed cavity 120, and the cover plate 121 is provided with a toggle part 122 for easy operation by the user. The toggle part 122 is a toggle block disposed 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 the locking tongue 310 is provided with a limiting groove 311 on the side away from the opening of the receiving 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 locking tongue 310. Specifically, when the wristband 200 is inserted into the receiving groove 110 and the locking tongue 310 is inserted into the locking groove 211, the limiting block 212 is correspondingly set with 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 wristband device is squeezed, it cannot be driven to move, thereby driving the locking tongue 310 to move. Thus, the risk of the locking tongue 310 falling off the locking groove 211 can be reduced, thereby reducing the risk of the wristband 200 falling off.

[0051] Please see Figure 4 and Figure 8In one embodiment of the present invention, a reset member 340 is provided between the locking component 300 and the main body 100; the reset member 340 drives the locking component 300 to move, thereby driving the latch 310 to insert into the receiving groove 110. In this embodiment, the reset member 340 can provide a thrust to drive the latch 310 to insert into the receiving groove 110. When inserting the wristband 200 into the receiving groove 110, the user only needs to release the pressing block 330 when the locking groove 211 corresponds to the latch 310, and the latch 310 will automatically insert into the locking groove 211 under the thrust of the reset member 340. The reset member 340 provided between the locking component 300 and the main body 100 enables the latch 310 to automatically insert into the locking groove 211. When installing the wristband 200, the user does not need to pull the pressing block 330, which simplifies the installation process of the wristband 200 and reduces the installation difficulty of the wristband 200. In one specific embodiment, the reset member 340 may be a helical spring.

[0052] Please see Figure 4 In one embodiment of the present invention, the end of the wristband 200 is provided with a first guide surface 230, and the locking tongue 310 is provided with a second guide surface 312, which can abut against the first guide surface 230. When the wristband 200 is inserted into the receiving groove 110, the first guide surface 230 abuts against the second guide surface 312. As the wristband 200 continues to be inserted, the wristband 200 drives the locking tongue 310 to move through the cooperation of the first guide surface 230 and the second guide surface 312, so that the locking tongue 310 gradually disengages from the receiving groove 110 until the locking tongue 310 corresponds to the locking groove 211. The locking tongue 310 will then automatically insert into the locking groove 211 under the pushing force of the reset member 340. The provision of the first guide surface 230 and the second guide surface 312 can reduce the difficulty for users to install the wristband 200. Specifically, when installing the wristband 200, the user only needs to insert the wristband 200 into the receiving groove 110. The locking tongue 310 will then move along the thickness direction of the main body 100 with the cooperation of the two guide surfaces, and when it corresponds to the locking groove 211, it will be pushed into the locking groove 211 by the reset member 340, locking the position of the wristband 200. During this process, the user does not need to continuously press the pressing block 330. In this embodiment, both the first guide surface 230 and the second guide surface 312 are inclined surfaces or arc surfaces; or the first guide surface 230 is one of the inclined surface and the arc surface, and the second guide surface 312 is the other of the inclined surface and the arc surface.

[0053] The present invention describes three different embodiments, the differences of which lie in the structure of the locking component 300 and the wristband 200. Specifically: Please refer to... Figure 2In Embodiment 1, the two ends of the locking tongue 310 are respectively disposed on both sides of the pressing block 330 along the width direction of the wristband 200. The wristband 200 is provided with an avoidance notch 220 and two locking grooves 211 communicating with the avoidance notch 220, and the two locking grooves 211 are disposed opposite to each other along the width direction of the wristband 200; please refer to Figure 5 In embodiment two, there are two locking tongues 310 and two locking grooves 211. The pressing block 330 is provided with a clearance space 331. The ends of the two locking tongues 310 facing each other are respectively provided with the clearance space 331. The two locking grooves 211 are arranged opposite to each other along the width direction of the wristband 200. Please refer to Figure 7 In embodiment three, the locking tongue 310 and the pressing block 330 are spaced apart along the depth direction of the receiving groove 110, and the wristband 200 is provided with a locking groove 211.

[0054] In addition, the pressing block 330 has two different installation methods. In one method, the end face of the pressing block 330 facing away from the base 320 is flush with the outer surface of the main body 100, and the main body 100 is provided with a movable cover plate 121 to cover the pressing block 330. In the other method, the pressing block 330 extends out of the outer surface of the main body 100, and the side of the locking tongue 310 facing away from the opening of the receiving groove 110 is provided with a limiting groove 311. The inner wall of the locking groove 211 is provided with a limiting block 212 that can be inserted into the limiting groove 311. When manufacturing the wristband 200 device, any installation method of the pressing block 330 can be selected and combined with any of the three embodiments mentioned above. In the embodiments of the present invention, the pressing blocks of Embodiment 1 and Embodiment 2 both adopt the first installation method, while the pressing block of Embodiment 3 adopts the second installation method.
