[0071] Currently, wrist-worn devices such as smart bracelets and smartwatches are widely used. These devices are aesthetically pleasing and can be used to monitor heart rate, blood oxygen, and other parameters. They are also used for Alipay payments and public transportation access control.

[0072] In related technologies, wrist-worn devices typically use a watch face with a strap. The watch face is worn and removed by repeatedly removing and removing the strap, causing users to repeatedly put on and take off the watch, which can cause discomfort to the user's wrist. Furthermore, the wearing and removing process is cumbersome and negatively impacts the user experience.

[0073] Based on the above concepts and problems, this invention proposes a wrist-worn device 100. It is understood that the wrist-worn device 100 can be a smart bracelet, smartwatch, etc., and is not limited thereto. The wrist-worn device 100 of this invention combines the watch face body 3 with the wearing structure 1, allowing the wearing structure 1 to be directly worn on the user's wrist without disassembly. Simply removing the watch face body 3 from the wearing structure 1 allows for charging, making the disassembly and assembly process simple and convenient to use.

[0074] In this embodiment, the wrist-worn device 100 can be a watch body, a smart watch face, or other structures. The watch face body 3 of the wrist-worn device 100 has an interface for display and operation, such as displaying time, heart rate data, blood oxygen data, and deduction information for contactless payment, etc., which are not limited here.

[0075] Please refer to the reference. Figures 1 to 18As shown, in this embodiment of the invention, the wrist-worn device 100 includes a wearing structure 1, an adjustment component 2, and a dial body 3. The wearing structure 1 includes a chassis component 11 and a wearing part 12. The wearing part 12 is connected to the chassis component 11 and cooperates with the chassis component 11 to form a wearing space. The chassis component 11 has a locking groove 1127 on the side facing away from the wearing space. The adjustment component 2 is disposed on the chassis component 11 and is used to adjust the locking groove 1127. The dial body 3 is provided with a locking member 33, which is used to lock or release the adjustment component 2. The dial body 3 is detachably disposed in the locking groove 1127 so that the wrist-worn device 100 has an assembled state and a disassembled state.

[0076] Understandably, when the wrist-worn device 100 is in the assembled state, the locking member 33 locks the adjusting component 2 so that the dial body 3 is engaged in the locking groove 1127; when the wrist-worn device 100 is in the disassembled state, the locking member 33 disengages from the adjusting component 2 so that the dial body 3 is disengaged from the locking groove 1127.

[0077] In this embodiment, as Figures 1 to 18 As shown, by configuring the wearing structure 1 as a chassis assembly 11 and a wearing part 12, it is convenient to install, assemble, and position the dial body 3 using the chassis assembly 11. In other words, the chassis assembly 11 provides the assembly position and space for the dial body 3. It is understood that the wearing part 12 can be a watch strap, bandage, or tie, etc. The wearing part 12 can be a single strap structure, with at least one end detachably connected to the chassis assembly 11 to form a wearing space, facilitating user wearing and removal. Alternatively, the wearing part 12 can be a two-part strap structure, in which case the two strap structures are respectively connected to opposite sides of the chassis assembly 11, and the two strap structures are detachably connected to form a wearing space, facilitating user wearing and removal. This is not limited here.

[0078] Understandably, the main body 3 of the watch face can be a watch body, a bracelet body, a watch face, or a smart device structure; no limitation is made here. The main body 3 includes a display screen, control circuitry, and power supply. The power supply is electrically connected to the control circuitry and the display screen to provide power, and the control circuitry is electrically connected to the display screen to control it. Of course, the main body 3 also includes modules for monitoring heart rate, blood oxygen, etc., as well as modules for Alipay payments, public transport access card swiping, etc.; these are not limited here.

[0079] In this embodiment, by providing a locking groove 1127 in the chassis assembly 11 of the wearing structure 1 and providing an adjustment component 2 in the chassis assembly 11, the locking groove 1127 is adjusted by the adjustment component 2 to facilitate the dial body 3 to engage with or disengage from the locking groove 1127. Furthermore, by providing a locking member 33 in the dial body 3, the adjustment component 2 is locked or released by the locking member 33, thereby preventing the user from accidentally touching the dial body 3 to disengage from the locking groove 1127.

[0080] Understandably, by detachably mounting the dial body 3 into the locking groove 1127, the wrist-wearing device 100 has both an assembled state and a disassembled state. That is, when the dial body 3 is mounted in the locking groove 1127 of the chassis assembly 11 in the wearing structure 1, the wrist-wearing device 100 is in an assembled state, such as... Figure 1 As shown, when the main body 3 of the watch face is detached or disassembled from the locking groove 1127 of the chassis assembly 11, the wrist-worn device 100 is in a disassembled state. At this time, the main body 3 of the watch face and the wearing structure 1 are separated into two parts, which makes it convenient to charge, repair or adjust the main body 3 of the watch face.

[0081] In this embodiment, when the wrist-worn device 100 is in the assembled state, the locking member 33 locks the adjusting component 2 so that the dial body 3 is engaged in the locking groove 1127. This securely locks the dial body 3 in the locking groove 1127 of the chassis component 11 in the wearing structure 1, and the dial body 3 will not easily fall off. When the wrist-worn device 100 is in the disassembled state, the locking member 33 disengages from the adjusting component 2 so that the dial body 3 disengages from the locking groove 1127, thereby separating the dial body 3 from the wearing structure 1.

[0082] The wrist-worn device 100 of the present invention comprises a wearing structure 1 consisting of a chassis assembly 11 and a wearing part 12, such that the wearing part 12 is connected to the chassis assembly 11 and cooperates with the chassis assembly 11 to form a wearing space, thereby facilitating the user's wearing and overall disassembly by utilizing the wearing part 12 in conjunction with the wearing space; simultaneously, by providing a locking groove 1127 on the side of the chassis assembly 11 facing away from the wearing space, and by providing an adjustment component 2 on the chassis assembly 11, the locking groove 1127 is adjusted using the adjustment component 2, and a locking member 33 is provided on the dial body 3, which locks or releases the adjustment component 2, thereby detachably mounting the dial body 3 onto the locking groove 112. 7. This allows the wrist-worn device 100 to have both an assembled state and a disassembled state. In the assembled state, the locking member 33 locks the adjusting component 2, so that the dial body 3 is engaged in the locking groove 1127, thus assembling the dial body 3 with the wearing structure 1. In the disassembled state, the locking member 33 disengages from the adjusting component 2, so that the dial body 3 is disengaged from the locking groove 1127, thereby allowing the dial body 3 to be disassembled from the wearing structure 1. This eliminates the need to remove the watch strap; the dial body 3 can be removed for charging and other operations. The disassembly and assembly of the dial body are simple and convenient to use.

[0083] In one embodiment, the chassis assembly 11 includes a bottom shell 111 and two movable outer shells 112. The bottom shell 111 is connected to the wearing part 12. The bottom shell 111 has a mounting cavity 1111, a through hole 1112 and two movable holes 1113. The through hole 1112 and the two movable holes 1113 are all connected to the mounting cavity 1111. One end of each movable outer shell 112 is movably disposed in the mounting cavity 1111, and the other end of each movable outer shell 112 is movably disposed through the movable hole 1113, so that the two movable outer shells 112 cooperate to form a locking groove 1127. The adjusting assembly 2 is disposed in the mounting cavity 1111 and is pulsatorically connected to the two movable outer shells 112 respectively. The adjusting assembly 2 has a locking part 211 that rotatably passes through the through hole 1112.

[0084] In this embodiment, as Figures 1 to 14 As shown, at least one side of the bottom shell 111 is connected to the wearing part 12, so that the wearing part 12 and the bottom shell 111 enclose a wearing space. The side of the bottom shell 111 facing away from the wearing space forms a mounting surface, and the bottom shell 111 has a mounting cavity 1111. By providing a through hole 1112 and two movable holes 1113 in the bottom shell 111 that communicate with the mounting cavity 1111, the through hole 1112 and the two movable holes 1113 are both arranged to pass through the mounting surface, and the two movable holes 1113 are optionally located on opposite sides of the through hole 1112. In this way, the two movable outer shells 112 are partially movably installed in the mounting cavity 1111, so that one end of each movable outer shell 112 movably passes through the movable hole 1113 and partially protrudes from the mounting surface, so that the movable outer shell 112 protruding from the mounting surface cooperates to form a locking groove 1127.

[0085] Understandably, by placing the adjusting component 2 within the mounting cavity 1111 and connecting it to the two movable housings 112 respectively, the movement of the two movable housings 112 can be controlled by the adjusting component 2, allowing them to move closer or further apart, thereby adjusting the size of the locking groove 1127. In this embodiment, the adjusting component 2 is provided with a locking part 211 that rotatably passes through the through hole 1112. When the dial body 3 is installed in the locking groove 1127, the locking part 211 is locked or released by the locking member 33 of the dial body 3, allowing the adjusting component 2 to adjust the size of the locking groove 1127.

[0086] In one embodiment, the adjusting assembly 2 includes a rotating shaft 21, two gear shafts 22, and at least two elastic elements 23. The rotating shaft 21 is rotatably disposed within the mounting cavity 1111, with one end of the rotating shaft 21 rotatably passing through a through hole 1112 and having a locking part 211. The rotating shaft 21 also has a first gear 213 located within the mounting cavity 1111. Both gear shafts 22 are rotatably disposed within the mounting cavity 1111, and each gear shaft 22 has a second gear 221 and a third gear 222. Both second gears 221 are meshed with the first gear 213. A movable housing 112 is provided with a gear part 1123 that meshes with a third gear 222. At least two elastic elements 23 are provided in the mounting cavity 1111. Each movable housing 112 is elastically connected to the inner wall of the mounting cavity 1111 through at least one elastic element 23. The rotating shaft 21 drives the first gear 213 to rotate, so that the first gear 213 simultaneously drives the two second gears 221 and the two third gears 222 to rotate, so that the two movable housings 112 move closer or further apart, thereby adjusting the locking groove 1127 to lock or release the dial body 3.

[0087] In this embodiment, as Figure 2 , Figures 4 to 7 , Figures 12 to 14 As shown, one end of the rotating shaft 21 is located in the mounting cavity 1111 and is rotatably connected to the bottom shell 111. The other end of the rotating shaft 21 is rotatably inserted through the through hole 1112 and is provided with a locking part 211, such that at least part of the locking part 211 is located in the locking groove 1127. By providing a first gear 213 on the rotating shaft 21, the first gear 213 is driven to be connected to two movable shells 112 located in the mounting cavity 1111. Each movable shell 112 is elastically connected to the inner wall of the mounting cavity 1111 through at least one elastic element 23. Thus, the rotating shaft 21 can drive the first gear 213 to rotate, so that the first gear 213 drives the two movable shells 112 to move closer or further away from each other, thereby adjusting the locking groove 1127 to lock or release the dial body 3.

[0088] Understandably, when the two movable housings 112 move away from each other, the elastic element 23 is stretched. The elastic tension of the elastic element 23 causes the two movable housings 112 to tend to move closer to each other, thereby locking the dial body 3 with the locking groove 1127.

[0089] To facilitate the disassembly and assembly of the main body 3 of the dial, in this embodiment, as follows: Figure 2 , Figures 4 to 7As shown, when the dial body 3 is installed into the locking groove 1127, pressing the dial body 3 into the locking groove 1127 from above causes the dial body 3 to be squeezed into the locking groove 1127 from top to bottom. At this time, the periphery of the dial body 3 pushes the two movable outer shells 112 outward to move in the horizontal direction. At this time, the two movable outer shells 112 drive the rotating shaft 21 to rotate through the transmission component. When the dial body 3 is installed in the locking groove 1127, the locking component 33 locks the locking part 211 of the rotating shaft 21 of the adjusting component 2 to prevent the rotating shaft 21 from rotating in case of accidental contact, so that the two movable outer shells 112 can move relative to each other. In this way, the assembly of the dial body 3 and the chassis component 11 of the wearing structure 1 can be completed.

[0090] When it is necessary to disassemble the main body 3 of the dial, in this embodiment, as follows: Figures 9 to 14 As shown, when the user rotates the main body 3 of the dial, the main body 3 drives the rotating shaft 21 to rotate. This causes the rotating shaft 21 to move the two movable outer shells 112 away from each other in the horizontal direction through the cooperation of the first gear 213 and the transmission component. This causes the locking groove 1127 to release the main body 3 of the dial. At this time, the main body 3 of the dial is pulled out of the locking groove 1127, so that the locking component 33 releases the locking part 211 of the rotating shaft 21. After the main body 3 of the dial is completely disengaged from the locking groove 1127, the two movable outer shells 112 are reset under the elastic action of the elastic component 23, thereby driving the rotating shaft 21 to reset.

[0091] Understandably, the first gear 213 of the rotating shaft 21 is connected to the two movable housings 112 via a transmission component. The transmission component can be a toothed, racked, or gear structure located on the movable housing 112, and is not limited here.

[0092] In this embodiment, the transmission component may be two gear shafts 22 and a gear section 1123 disposed in the movable housing 112. For example... Figure 2 , Figures 4 to 7 , Figure 13 and Figure 14 As shown, two gear shafts 22 are rotatably mounted in the mounting cavity 1111 and are respectively connected to two movable housings 112. By providing a second gear 221 and a third gear 222 on the gear shafts 22 and a gear section 1123 on the movable housings 112, the second gear 221 of the two gear shafts 22 meshes with the first gear 213 of the rotating shaft 21, and the third gear 222 of the two gear shafts 22 meshes with the gear section 1123 of the two movable housings 112, thus realizing the transmission connection between the rotating shaft 21 and the two movable housings 112.

[0093] Understandably, in order to convert the rotation of the rotating shaft 21 around the axial direction into the horizontal movement of the two movable housings 112 (that is, the movement in a direction perpendicular to the axial direction of the rotating shaft 21), the first gear 213 can be a bevel gear, which is disposed around the outer wall of the rotating shaft 21, and the second gear 221 can be a bevel gear, which is disposed at one end of the gear shaft 22 near the rotating shaft 21. This facilitates the meshing connection between the first gear 213 and the second gear 221, thereby achieving a self-locking function with the cooperation of the locking member 33 of the dial body 3, and preventing accidental touch.

[0094] Optionally, the third gear 222 is a coaxial gear, which surrounds the outer wall of the gear shaft 22 and is spaced apart from the second gear 221, so that the third gear 222 meshes with the gear portion 1123 of the movable housing 112. Optionally, the gear portion 1123 is a rack or teeth provided on the movable housing 112.

[0095] In this embodiment, the axial direction of the gear shaft 22 can optionally be perpendicular to the axial direction of the rotating shaft 21, so that the rotation of the rotating shaft 21 around the axial direction can be converted into the movement of the two movable housings 112 in the horizontal direction (that is, in the direction perpendicular to the axial direction of the rotating shaft 21).

[0096] Optionally, the two gear shafts 22 are aligned axially and located on opposite sides of the rotating shaft 21. This allows the rotating shaft 21 to rotate synchronously and in a balanced manner, ensuring the movement of the two movable housings 112.

[0097] In one embodiment, the elastic element 23 includes a plurality of elastic elements, and each movable housing 112 is provided with at least one elastic element 23 on both sides perpendicular to the moving direction.

[0098] In this embodiment, as Figure 14 As shown, by providing at least one elastic element 23 on each side of the moving direction of the movable housing 112, it is ensured that the movable housing 112 locks the dial body 3 or resets under the elastic force of the elastic element 23.

[0099] In one embodiment, each movable housing 112 includes a base plate 1121 and a limiting plate 1126 arranged at an angle. The base plate 1121 is movably disposed in the mounting cavity 1111. The base plate 1121 has an extension portion 1122 extending toward another base plate 1121. The extension portion 1122 has a gear portion 1123. The rotating shaft 21 and the second gear 221 are both located between the two extension portions 1122. One end of the extension portion 1122 adjacent to the other base plate 1121 has a stop protrusion 1124. The base plate 1121 also has a first baffle 1125 connected to the elastic member 23. The inner wall of the mounting cavity 1111 has a second baffle 1114 corresponding to the first baffle 1125. The elastic member 23 is located between the first baffle 1125 and the second baffle 1114 and is connected to the first baffle 1125 and the second baffle 1114.

[0100] In this embodiment, as Figures 2 to 8 , Figures 10 to 14 As shown, by setting the movable outer shell 112 as a base plate 1121 and a limiting plate 1126, the base plate 1121 and the limiting plate 1126 can optionally be arranged vertically, so that the base plate 1121 is movably accommodated in the mounting cavity 1111, and the end of the limiting plate 1126 away from the base plate 1121 is movably inserted through the movable hole 1113, so that part of the limiting plate 1126 protrudes from the mounting surface of the base shell 111, thereby forming a locking groove 1127.

[0101] Understandably, the base plate 1121 is provided with an extension portion 1122 extending toward another base plate 1121. By providing a gear portion 1123 in the extension portion 1122, the extension portion 1122 is limited between the bottom wall of the base shell 111 and the third gear 222 of the gear shaft 22. By engaging the third gear 222 with the gear portion 1123, the base plate 1121 can be limited by the gear shaft 22 and the bottom wall of the base shell 111, and the base plate 1121 can move under the cooperation of the third gear 222 and the gear portion 1123.

[0102] Optionally, the rotating shaft 21 and the second gear 221 are both located between the two extensions 1122 of the two movable housings 112.

[0103] In this embodiment, as Figure 14As shown, a stop protrusion 1124 is provided at one end of the extension 1122 adjacent to the other base plate 1121, thereby blocking the third gear 222 of the gear shaft 22 and preventing the extension 1122 of the base plate 1121 from disengaging from the third gear 222 of the gear shaft 22. It can be understood that by providing a first baffle 1125 and a second baffle 1114 on the inner walls of the base plate 1121 and the mounting cavity 1111 respectively, the elastic member 23 can be installed using the first baffle 1125 and the second baffle 1114, thereby improving installation stability while ensuring the elastic force of the elastic member 23.

[0104] Understandably, the second baffle 1114 may optionally protrude from the bottom wall of the mounting cavity 1111, and the bottom plate 1121 has a clearance space corresponding to the second baffle 1114. Optionally, the two movable housings 112 are symmetrically arranged. In this embodiment, the two bottom plates 1121 of the two movable housings 112 are symmetrically arranged with the pivot 21 as the center of symmetry, which is not limited here.

[0105] In one embodiment, the wall of the locking groove 1127 is provided with a locking protrusion 1128, and the periphery of the dial body 3 is provided with a locking groove 314; in the assembled state, the locking protrusion 1128 is limited to the locking groove 314.

[0106] In this embodiment, as Figures 2 to 7 , Figures 10 to 15 , Figure 17 As shown, by further providing a locking protrusion 1128 on the groove wall of the locking groove 1127, and providing a locking slot 314 on the periphery of the dial body 3, when the dial body 3 is installed in the locking groove 1127, that is, when the wrist-worn device 100 is in the assembled state, the locking protrusion 1128 is limited to the locking slot 314, so as to further achieve the fastening and locking of the dial body 3.

[0107] In one embodiment, one of the locking part 211 and the locking member 33 is provided with a limiting protrusion 212, and the other is provided with a limiting hole 332; in the assembled state, the limiting protrusion 212 is limited within the limiting hole 332.

[0108] In this embodiment, as Figure 2 , Figures 4 to 8 , Figures 10 to 14 , Figures 16 to 18 As shown, by providing a limiting protrusion 212 and a limiting hole 332 on the locking part 211 and the locking member 33 respectively, when the dial body 3 is installed in the locking groove 1127, that is, when the wrist-worn device 100 is in the assembled state, the limiting protrusion 212 is limited within the limiting hole 332, thereby using the limiting hole 332 of the locking member 33 to limit the limiting protrusion 212 of the locking part 211, thereby achieving self-locking.

[0109] In one embodiment, the dial body 3 includes a dial housing 31 and a screen 32. The dial housing 31 includes an upper dial shell 311 and a lower dial shell 312. The upper dial shell 311 and the lower dial shell 312 enclose a receiving cavity 313. The upper dial shell 311 is provided with a mounting port 3111 communicating with the receiving cavity 313. The lower dial shell 312 is provided with a fixing groove 3121 on the side opposite to the receiving cavity 313. A locking member 33 is movably disposed in the fixing groove 3121. The outer side wall of the dial housing 31 is provided with a locking slot 314 adjacent to the lower dial shell 312. The screen 32 is disposed at the mounting port 3111.

[0110] In this embodiment, as Figures 1 to 11 , Figures 15 to 18 As shown, the dial housing 31 of the dial body 3 is used to install, fix, and protect the screen 32, as well as control circuits, power supply, or other module components, etc., which are not limited here. In order to improve the sealing performance of the cavity 313 inside the dial housing 31, the upper dial shell 311 and the lower dial shell 312 of the dial housing 31 can be fixed by welding or adhesive.

[0111] Understandably, the screen 32 is sealed and installed at the mounting port 3111 of the upper casing 311 of the dial, and is electrically connected to the control circuit, power supply, or other module components within the accommodating cavity 313. The screen 32 is used for display or operation. In this embodiment, by providing a fixing groove 3121 in the lower casing 312 of the dial, and movably placing the locking member 33 within the fixing groove 3121, the adjusting component 2 can be locked or released by the locking member 33 without affecting the appearance and sealing performance of the dial body 3.

[0112] Optionally, the outer wall of the dial housing 31 is provided with a locking groove 314. In this embodiment, the locking groove 314 is optionally arranged in an arc shape with the fixing groove 3121 as the center, so as to facilitate the rotation and disassembly of the dial body 3.

[0113] In one embodiment, the dial body 3 is provided with a guide slope 315 around its periphery; in the assembled state, the locking protrusion 1128 slides along the guide slope 315 so that the dial body 3 is engaged in the locking groove 1127.

[0114] In this embodiment, as Figures 2 to 7 , Figure 15 and Figure 16 As shown, by providing a guide slope 315 around the bottom surface of the dial body 3, the guide slope 315 corresponds to the movable outer shell 112. Therefore, when the dial body 3 is installed in the locking groove 1127, the dial body 3 is pressed down, causing the locking protrusion 1128 to slide along the guide slope 315, so that the dial body 3 is engaged within the locking groove 1127. It can be understood that the guide slope 315 guides and directs the dial body 3 as it is pressed down and installed in the locking groove 1127.

[0115] In one embodiment, the locking member 33 includes a positioning member 331 and a resetting member 334. The positioning member 331 is movably disposed in the fixing groove 3121 and has a limiting hole 332. The resetting member 334 is disposed in the fixing groove 3121 and is elastically connected to the groove wall of the positioning member 331 and the fixing groove 3121. The adjusting component 2 is provided with a limiting protrusion 212. In the assembled state, part of the adjusting component 2 enters the fixing groove 3121 and presses against the positioning member 331 to compress the resetting member 334, so that the limiting protrusion 212 is limited to the limiting hole 332.

[0116] In this embodiment, as Figure 2 , Figures 4 to 8 , Figure 10 , Figure 11 , Figures 16 to 18 As shown, by movably placing the positioning member 331 in the fixed groove 3121 and elastically connecting it to the fixed groove 3121 through the reset member 334, the positioning member 331 can move up and down along the axial direction of the fixed groove 3121. This allows the locking member 33 to be used to lock the locking part 211 of the adjustment assembly 2 without affecting the rotation of the shaft 21 of the adjustment assembly 2.

[0117] In one embodiment, one of the positioning member 331 and the fixing groove 3121 is provided with a sliding protrusion 333, and the other is provided with a sliding groove 3122. The sliding protrusion 333 is slidably limited within the sliding groove 3122. The extending directions of the sliding protrusion 333 and the sliding groove 3122 are consistent with the extension and retraction directions of the reset member 334.

[0118] Understandable, such as Figure 8 , Figure 17 and Figure 18 As shown, by providing sliding protrusions 333 and sliding grooves 3122 on the groove walls of positioning member 331 and fixing groove 3121 respectively, positioning member 331 is guided in the axial direction of fixing groove 3121 and limited in the circumferential direction.

[0119] The wrist-worn device 100 of the present invention presses the dial body 3 in the Z direction, causing the locking protrusions 1128 of the two movable shells 112 of the chassis assembly 11 in the wearing structure 1 to move along the guide slope 315 of the dial body 3, thereby causing the two movable shells 112 to move towards the two ends of the dial body 3 respectively. During this process, the rotating shaft 21 of the adjusting assembly 2 rotates under the meshing transmission of each gear. In order to insert the locking protrusions 1128 on the movable shells 112 into the locking slots 314 of the dial body 3, the rectangular limiting protrusions 212 on the rotating shaft 21 are successfully inserted into the rectangular limiting holes 332 of the locking member 33. A reset member 334 is installed between the positioning member 331 and the fixing groove 3121 of the locking member 33. The reset member 334 can be selected as a spring, which cleverly realizes the positioning of the dial body 3.

[0120] Understandably, the gear part 1123 on the movable housing 112 is driven by the gear shaft 22 of the adjusting component 2 and the rotating shaft 21 through gear meshing. That is, the first gear 213 is meshed with the second gear 221 of the gear shaft 22, and the third gear 222 of the gear shaft 22 is meshed with the gear part 1123 on the movable housing 112, thus realizing meshing transmission. The movement of the movable housing 112 to both ends and the rotation of the rotating shaft 21 are mutually converted to realize the installation and removal of the dial body 3. The operation is simple, and at the same time, the wrist-worn device 100 can be made to achieve long-term wear of the watch strap without removing the watch strap. Only the watch body 3 needs to be installed and removed, so that the watch strap can be worn for a long time and the damage caused by removing the watch strap can be reduced.

[0121] In this embodiment, as Figure 1 , Figure 9 , Figure 12 and Figure 15 As shown, the wrist-worn device 100 includes a watch face body 3 and a wearing structure 1. The exterior components of the watch face body 3 mainly include the upper watch face 311 and the lower watch face 312 of the watch face housing 31, and the screen 32. The upper watch face 311 is fixedly connected to the screen 32 and the lower watch face 312 with adhesive. The bottom shell 111 of the chassis assembly 11 is connected to the long and short watch straps of the wearing part 12 at both ends, respectively. The lower shell and the cover plate of the bottom shell 111 are fixedly connected with adhesive. A rotating shaft 21 and two movable outer shells 112 are installed between the lower shell and the cover plate of the bottom shell 111. A first gear 213 is installed between the rotating shaft 21 and the bottom shell 111 through a retaining spring. Two gear shafts 22 are installed on the bottom shell 111. A third gear 222 and a second gear 221 are installed on the gear shafts 22. The first gear 213 meshes with the two second gears 221 for transmission. A gear section 1123 is designed on the movable housing 112, which meshes with the third gear 222 for transmission. As the movable housing 112 moves toward both ends of the dial body 3, the elastic element 23 is compressed.

[0122] Understandably, the lower dial shell 312 of the dial housing 31 is provided with a spring fixing cover. The spring fixing cover is fixedly connected to the lower dial shell 312 with adhesive. A fixing groove 312 is formed between the spring fixing cover and the lower dial shell 312. A locking member 33 is installed in the fixing groove 312. A reset member 334 is installed on the positioning member 331 of the locking member 33.

[0123] In this embodiment, as Figure 2 , Figures 4 to 7 As shown, the main body 3 of the dial is arranged according to... Figure 2 Pressing down in the direction of the arrow (vertical direction), the dial body 3 pushes the two movable outer shells 112 away from each other in the horizontal direction as indicated by the arrow. When the locking protrusion 1128 moves along the guide slope 315 to the locking groove 314, the locking part 211 of the rotating shaft 21 pushes the positioning part 331 of the locking member 33 to move upward along the fixing groove 3121. At this time, the positioning part 331 is cooperated with the sliding protrusion 333 and the sliding groove 3122, which restricts the circumferential rotation of the positioning part 331 in the fixing groove 3121, and it can only rotate in the direction of the arrow. When the fixed groove 3121 moves axially (i.e., moves vertically upward), the reset member 334 is compressed. When the locking protrusion 1128 is engaged in the locking groove 314, the two movable outer shells 112 drive the rotating shaft 21 to rotate under the elastic tension of the elastic member 23. When the limiting protrusion 212 of the locking part 211 corresponds to the limiting hole 332 of the positioning member 331, the positioning member 331, under the elastic reset of the reset member 334, makes the limiting protrusion 212 limited within the limiting hole 332 of the positioning member 331.

[0124] Understandable, such as Figures 2 to 8 The diagram shows the installation process of the main body 3 of the dial. Figure 2 As shown, the dial body 3 is mounted in the Z direction, and the guide slope 315 on the dial body 3 contacts the movable outer casing 112, as... Figure 3 As shown, continue pressing down on the dial body 3. The two movable outer shells 112 move towards both ends of the dial body 3, as indicated by the arrows in section 2. During the movement of the movable outer shells 112, the gears of the adjusting component 2 in the mounting cavity 1111 of the chassis assembly 11 engage with each other. The gear part 1123 on the movable outer shell 112 meshes with the third gear 222, driving the second gear 221 of the gear shaft 22 to rotate. The second gear 221 meshes with the first gear 213, causing the first gear 213 to rotate clockwise, driving the rotating shaft 21 to rotate clockwise. During the movement of the movable outer shells 112, the elastic element 23 is compressed. Press the dial body 3 until... Figure 4As shown, the movable outer shell 112 moves to contact both ends of the bottom shell 111, and the bottom surface of the positioning member 331 of the locking member 33 contacts the upper surface of the rotating shaft 21. At this time, the rotating shaft 21 rotates until the long side of the rectangular limiting protrusion 212 on the rotating shaft 21 forms a certain angle with the horizontal line. Continuing to press the dial body 3, the rotating shaft 21 pushes the positioning member 331 upwards, and the reset member 334 is compressed, as shown... Figure 5 As shown. Continue pressing the dial body 3 to... Figure 6 As shown, the positioning component 331 moves until its upper surface coincides with the lower surface of the spring fixing cover. The compressed elastic component 23 inside the chassis assembly 11 resets, driving the movable outer shell 112 back to its initial position. The locking protrusion 1128 on the movable outer shell 112 inserts into the locking slot 314 of the dial body 3, positioning the dial body 3 in the Z direction. After the rectangular limiting protrusion 212 on the rotating shaft 21 rotates into the rectangular limiting hole 332 on the lower surface of the positioning component 331, the reset component 334 resets, and the positioning component 331 moves downward, as shown. Figure 7 and Figure 8 As shown, the position of the main body 3 of the dial on the horizontal plane is determined, and the main body 3 of the dial is completely positioned.

[0125] It should be noted that during the installation of the dial body 3, it is only necessary to install the dial body 3 in the Z direction and press it down. The movable outer shell 112 first moves to both ends respectively, and then resets under the action of the elastic element 23. The locking protrusion 1128 on the movable outer shell 112 positions the dial body 3 in the Z direction. The rotating shaft 21 first rotates a certain angle and then returns to the initial position. The rectangular limiting protrusion 212 on the rotating shaft 21 enters the rectangular limiting hole 332 on the bottom surface of the positioning element 331, so that the dial body 3 is fixed in the horizontal position. This process is simple to operate.

[0126] In this embodiment, as Figures 9 to 11 The diagram shown illustrates the disassembly process of the main body 3 of the watch face. Figure 9 As shown, rotating the dial body 3 in the direction of the arrow causes the positioning component 331 of the dial body 3 to rotate accordingly; Figure 10 As shown, the positioning component 331 rotates while simultaneously driving the rotating shaft 21 to rotate. A locking groove 314 is provided on the dial body 3, serving two purposes: first, it allows the locking protrusion 1128 on the movable outer shell 112 to insert into the locking groove 314, thus positioning the dial body 3; second, it provides clearance for the rotation of the dial body 3. Understandably, as the rotating shaft 21 rotates, the gears in the chassis assembly 11 engage with each other, causing the movable outer shell 112 to move towards both ends of the dial body 3. Figure 11 As shown, the locking protrusion 1128 disengages from the locking slot 314, allowing the dial body 3 to be removed in the Z direction. After the dial body 3 is removed, the elastic element 23 resets, and the movable outer shell 112 returns to its initial position. Thus, by rotating the dial body 3 clockwise, it can be removed in the Z direction, making the operation simple and convenient.
