[0031] And / or, the button is further provided with a first abutting member, and the module body is also provided with a first abutting block. When the sliding end of the button abuts against the second abutting block, the first abutting member abuts against the first abutting block.

[0032] According to another aspect of this application, a smartwatch is further provided, including any of the strap adjustment structures described in the preferred embodiments above, a main unit, and a strap. The main unit is mounted on the top of the base of the strap adjustment structure; the strap is mounted on the movable lug module of the strap adjustment structure; when the button of the strap adjustment structure is pressed for the first time, the movable lug module can move on the base to adjust the wearing length of the strap; when the button is pressed for the second time, the movable lug module can be separated from the strap.

[0033] Compared with the prior art, the watch strap adjustment structure and smartwatch provided by the present invention have at least one of the following beneficial effects:

[0034] 1. The snap fastener is designed to snap into the slot on the base. Simply press the button, and the sliding motion of the movable lugs on the base will change the distance between the movable lugs at both ends of the base along its length, thereby changing the length of the watch strap. It is simple to operate, convenient to use, and provides a good user experience.

[0035] 2. After releasing the button, the first elastic element pushes the spring buckle to move in the opposite direction, so that the first end of the spring buckle re-abuts against the slot, fixing the movable watch lug module in the wearing position, making the wearing process simple and effortless.

[0036] 3. The first end of the snap fastener is tilted away from the button. When shortening the strap length, simply push the module bodies at both ends of the base length direction to move towards each other and make the first end of the snap fastener reach the next slot. This simplifies the process of shortening the strap length and improves the user experience.

[0037] 4. After pressing the button again, the button's abutting part can push the watch strap spring bar away from the third opening, realizing the disassembly and separation of the watch strap from the movable lug module without affecting the original watch strap's versatility, resulting in a good operating experience; at the same time, when the button is pressed again, both the second and third elastic components provide damping, making the force required to press the button again significantly increase, thus improving the user experience.

[0038] 5. In the first state, the third elastic element pushes the end of the push rod near the abutting part to abut against the second abutting block, so as to avoid the third elastic element interfering with the initial pressing of the button; when the button is in the third state, the first abutting element abuts against the first abutting block to prevent the button from re-entering the first opening, causing the pressing part of the button to fully enter the first opening and abut against the inner wall of the first opening, so that the button cannot be reset and the watch strap adjustment structure malfunctions.

[0061] refer to Figures 1 to 4 This invention provides a watch strap adjustment structure for adjusting the wearing length of a watch strap 3. The watch strap adjustment structure includes a base 1 and a movable lug module 2. The base 1 is provided with a plurality of slots 12 spaced apart. The movable lug module 2 includes a module body 21, a button 22, and a snap fastener 23. The module body 21 is slidably mounted on the base 1 and is adapted to connect to the watch strap 3. The snap fastener 23 is movably mounted inside the module body 21, and a first elastic element 235 is provided between the snap fastener 23 and the module body 21. One end of the snap fastener 23 is adapted to pass through the module body 21 and abut against the slot 12, and the other end of the snap fastener 23 is adapted to abut against the button 22. When the button 22 is pressed, the button 22 pushes the snap fastener 23 to squeeze the first elastic element 235 and move the snap fastener 23 away from the slot 12, so that the movable lug module 2 can move and adjust the wearing length of the watch strap 3.

[0062] In this embodiment, the snap 23 is adapted to engage with the slot 12 on the base 1. By simply pressing the button 22, the distance between the movable watch lugs 2 at both ends of the base 1 can be changed by sliding the movable watch lugs 2 on the base 1, thereby changing the wearing length of the watch strap 3. The operation is simple, convenient, and provides a good user experience.

[0063] Specifically, the watch strap 3 connects to the movable lug module 2. By changing the spacing between the lug modules 2 on both sides of the movable base 1 along its length, the spacing between the two ends of the watch strap 3 changes, thereby adjusting the wearing length of the watch strap 3. (Reference) Figure 2 The bottom of the base 1 is provided with a first sliding groove 11, and the slot 12 is provided at the bottom of the first sliding groove 11; the movable lug module 2 is provided at the four corners of the base 1, and the top of the module body 21 is also provided with a slider 211. The slider 211 is engaged in the first sliding groove 11 on both sides. The cross-section of the slider 211 and the first sliding groove 11 is T-shaped, so that the module body 21 is slidably installed on the bottom of the base 1. The module bodies 21 at both ends of the base 1 along its length can move relative to or towards each other at the bottom of the base 1, thereby changing the distance between the module bodies 21 at both ends of the base 1 along its length, and thus changing the wearing length of the watch strap 3 connected to the module bodies 21; the slider 211 is also provided with a first opening 2111 at one end near the slot 12; the snap 23 has a first end 231, which is adapted to pass through the first opening 2111 of the slider 211 and engage with the slot 12. When the first end 231 of the snap 23 moves away from the slot 12, the slider 211 and the first groove 11 engage, so that the module body 21 is always connected to the base 1.

[0064] It is worth noting that module bodies 21 are provided on both sides of the base 1 in the width direction, and each module body 21 is equipped with a button 22. The watch strap adjustment mechanism will only be triggered when both module bodies 21 on both sides of the base 1 in the width direction are pressed simultaneously, to prevent the watch strap adjustment mechanism from being triggered under abnormal circumstances. At the same time, the cross-section of the slider 211 and the first slide groove 11 includes, but is not limited to, a T-shape. As long as the module body 21 is slidably installed at the bottom of the base 1, it is within the protection scope of this application.

[0065] Further, refer to Figure 6 and Figure 7 The spring clip 23 also includes a second end 232 and a third end 233. A spring groove 234 is provided between the second end 232 and the third end 233. The spring groove 234 is suitable for placing the first elastic element 235. The module body 21 has a mounting position 212 inside. The first elastic element 235 abuts between the second end 232 and the mounting position 212. The third end 233 slides against the button 22, and the button 22 can push the first end 231 away from the slot 12.

[0066] In this embodiment, after the button 22 is released, the first elastic element 235 pushes the snap 23 to move in the opposite direction, so that the first end 231 of the snap 23 re-abuts against the slot 12, fixing the movable watch ear module 2 in the wearing position, making the wearing process simple and effortless.

[0067] Specifically, the side of the first elastic member 235 away from the second end 232 abuts against the mounting position 212, and the first elastic member 235 is positioned relative to the spring groove 234 between the second end 232 and the third end 233, which can prevent the first elastic member 235 from shifting and improve the stability of the watch strap adjustment structure. A second opening is provided on one side of the module body 21; Reference Figure 10 The button 22 includes a pressing part 221 and a sliding part 222. The pressing part 221 is adapted to pass through the second opening. The sliding part 222 is provided with a second sliding groove 2221. The side of the second sliding groove 2221 near the spring buckle 23 is also provided with a first section 2222. The first section 2222 is inclined. The depth of the side of the first section 2222 near the pressing part 221 is greater than the side of the first section 2222 away from the pressing part 221. The third end 233 of the spring buckle 23 is slidably installed on the first section 2222. In the embodiment, the contact surface between the third end 233 of the spring buckle 23 and the first section 2222 is also inclined. After pressing the pressing part 221, the third end 233 slides along the first section 2222 and reaches the second section 2223. If the button 22 is pressed again, the apex of the inclined surface of the third end 233 contacts the second section 2223 and slides on the second section 2223. After the pressing part 221 is pushed, the third end 233 of the spring clip 23 slides along the first segment 2222 of the sliding part 222, causing the first end 231 of the spring clip 23 to move away from the slot, and the spring clip 23 presses the first elastic member 235. When the pressing part 221 of the button 22 is released, the first elastic member 235 releases its elasticity and pushes the button 22 to move in the opposite direction, causing the third end 233 of the spring clip 23 to slide along the tail end of the first segment 2222 of the sliding part 222 to the head end of the first segment 2222, and causing the first end 231 of the spring clip 23 to engage with the slot 12.

[0068] It is worth noting that the second slide groove 2221 also has a horizontally arranged second section 2223 on the side away from the snap 23. When the button 22 is pressed again, the third end 233 of the snap 23 slides on the second section 2223 and pushes the watch strap spring bar 31 to move. At this time, the first end 231 of the snap 23 is always away from the slot 12. The first elastic element 235 includes, but is not limited to, a compression spring. Moreover, in this embodiment, the first elastic element 235 is disposed inside the module body 21 and is disposed opposite to the snap 23 and the module body 21. In a modified embodiment, the first elastic element 235 can also be disposed outside the module body 21 and is disposed opposite to the first end 231 and the outer wall of the module body 21.

[0069] In a modified embodiment, the second slide groove 2221 further includes a third section, which is inclined and connects the first section 2222 and the second section 2223. The third section facilitates the movement of the third end 233 of the snap fastener 23 back and forth between the first section 2222 and the second section 2223. At this time, the first section 2222 and the second section 2223 are horizontally arranged. The depth of the first section 2222 of the second slide groove 2221 near the snap fastener 23 is greater than the depth of the second section 2223 of the second slide groove 2221 away from the snap fastener 23. The third end 233 of the snap fastener 23 is slidably installed in the second slide groove 2221. After pressing the pressing part 221, the third end 233 of the snap fastener 23 slides from the first section 2222 of the sliding part 222 along the third section to the second section 2223 and moves the first end 231 of the snap fastener 23 away from the slot 12. The snap fastener 23 presses the first elastic element 235. At this time, the distance between the two module bodies 21 in the length direction of the base 1 can be adjusted, thereby adjusting the wearing length of the watch strap 3. When the pressing part 221 of the button 22 is released, the first elastic element 235 releases its elasticity and pushes the button 22 to move in the opposite direction, so that the third end 233 of the snap 23 slides along the second section 2223 of the sliding part 222 to the first section 2222 and the first end 231 of the snap 23 is engaged in the slot 12.

[0070] Furthermore, the first end 231 of the snap 23 is tilted away from the button 22, and the corresponding position of the slot 12 is also tilted, so that the first end 231 of the snap 23 can slide along the slot 12 and shorten the length of the watch strap 3.

[0071] In this embodiment, the first end 231 of the snap fastener 23 is tilted away from the button 22. When shortening the wearing length of the watch strap 3, it is only necessary to push the module bodies 21 at both ends of the base support 1 in the length direction to move towards each other and make the first end 231 of the snap fastener 23 reach the next slot 12, which simplifies the process of shortening the wearing length of the watch strap 3 and improves the user experience.

[0072] Specifically, the first end 231 of the snap fastener 23 has a sloping surface on the side away from the button 22, and a vertical surface on the side closer to the button 22. The corresponding positions in the slot 12 also have sloping and vertical surfaces, ensuring that the module bodies 21 at both ends of the base 1 can only move towards each other and not in opposite directions. To shorten the wearing length of the watch strap 3, simply push the module body 21 inwards. Inside the module body 21, the first end 231 of the snap fastener 23 slides along the side wall of the slot 12 and presses against the first elastic element 235. When the first end 231 reaches the next slot 12, the first elastic element 235 releases its elasticity and pushes the first end 231 into the next slot 12. At this point, the wearing length of the watch strap 3 is shortened, making the operation convenient and simple.

[0073] It is worth noting that this embodiment is a preferred embodiment. Alternatively, pressing button 22 can control the first end 231 of the snap 23 to move away from the slot 12, and then push the module bodies 21 to move towards each other or push one module body 21 closer to another module body 21, thereby shortening the wearing length of the watch strap 3. That is, at this time, both sides of the first end 231 are vertical surfaces, and the corresponding position of the slot 12 is also a vertical surface, making it impossible to directly push the module body 21 to move and shorten the wearing length of the watch strap 3. Both pressing button 22 and shortening the wearing length of the watch strap 3 require pressing the button 22 to move the first end 231 away from the slot 12. This embodiment provides better stability, preventing accidental shortening of the watch strap 3 and compression of the user's skin, thus improving the user's wearing experience.

[0074] Further, refer to Figure 4 , Figure 8 and Figure 9 The watch strap 3 has strap spring bars 31 on both sides, and a second elastic element 32 is provided between the strap spring bars 31; the module body 21 also has a third opening 216, and the strap spring bars 31 are adapted to extend into the third opening 216; the button 22 also includes an abutment part 223, which is located on the side near the third opening 216, and there is a gap between the abutment part 223 and the strap spring bars 31; after pressing the button 22, the first end 231 of the snap 23 separates from the slot 12, so that the wearing length of the watch strap 3 can be adjusted; after pressing the button 22 again, the abutment part 223 is adapted to push the strap spring bars 31 away from the third opening 216 and squeeze the second elastic element 32, so that the watch strap 3 separates from the movable lug module 2.

[0075] In this embodiment, after pressing button 22 again, the abutting part 223 of button 22 can push the spring bar 31 of the watch strap away from the third opening 216, realizing the disassembly and separation of the watch strap 3 from the movable lug module 2 without affecting the universality of the original watch strap 3, and providing a good operating experience.

[0076] Specifically, refer to Figures 12 to 14The button 22 has a first state, a second state, and a third state. In the first state, the pressing part 221 of the button 22 extends out of the second opening, the third end 233 of the snap 23 is located on the first section 2222 of the sliding part 222, the first end 231 of the snap 23 is engaged in the slot 12, the spring bar 31 of the watch strap extends into the third opening 216, and there is a gap between the abutting part 223 of the button 22 and the spring bar 31 of the watch strap. At this time, the base 1, the movable lug module 2, and the spring bar 31 of the watch strap are mutually engaged. In the second state, the pressing part 221 on the button 22 enters the second opening, the third end 233 of the snap 23 is located at the first end of the second section 2223 of the sliding part 222, the snap 23 moves downward and compresses the first elastic member 235, the abutting part 223 of the button 22 contacts the end face of the watch strap spring bar 31, but does not push the watch strap spring bar 31 to move, the watch strap spring bar 31 is still located in the third opening 216, at this time the module body 21 can be moved to adjust the wearing length of the watch strap 3. In the third state, the pressing part 221 on the button 22 is fully inserted into the second opening, the third end 233 of the snap 23 is located at the end of the second section 2223 of the sliding part 222, the end of the push rod 24 near the spring bar 31 of the watch strap is flush with the end face of the third opening 216, and the spring bar 31 of the watch strap is pushed away from the third opening 216 by the abutting part 223 of the button 22. At this time, the spring bar 31 of the watch strap 3 is separated from the module body 21, and the watch strap 3 can be detached.

[0077] It is worth noting that there are two spring bars 31 on the watch strap, located opposite each other at the ends of the watch strap 3 in the width direction. A second elastic element 32 is provided between the two spring bars 31. Both the spring bars 31 and the second elastic element 32 are located on the inner side of the end of the watch strap 3. The abutting part 223 of the button 22 pushes the spring bar 31 away from the third opening 216 and squeezes the second elastic element 32. When the button 22 is released or the watch strap 3 is removed, the second elastic element 32 releases its elasticity and pushes the spring bar 31 back to its original position. At the same time, the second elastic element 32 also provides damping when the button 22 is pressed again, increasing the required force to press the button 22 again, making it easier for the user to distinguish the state of the button 22, and improving the user's pressing feel. The second elastic element 32 also includes, but is not limited to, a compression spring.

[0078] Further, refer to Figure 11It also includes a push rod 24, which is disposed inside the movable lug module 2 and is located between the button 22 and the watch strap spring bar 31. One end of the push rod 24 is adapted to pass through the third opening 216 and the other end of the push rod 24 is left with a gap between it and the watch strap spring bar 31. After the button 22 is pressed, the push rod 24 pushes the push rod 24 to contact the end face of the watch strap spring bar 31. After the button 22 is pressed again, the abutment part 223 pushes the push rod 24 and the watch strap spring bar 31 to move, so that the watch strap spring bar 31 leaves the third opening 216. When the button 22 is released, the second elastic element 32 pushes the watch strap spring bar 31 to extend into the third opening 216.

[0079] In this embodiment, when button 22 is pressed again, both the second elastic element 32 and the third elastic element 241 provide damping, which significantly increases the force required to press button 22 again, thus improving the user experience.

[0080] Specifically, when button 22 is pressed for the first time, the third end 233 of the snap 23 slides along the first segment 2222 of the sliding portion 222 and reaches the beginning of the second segment 2223. At this time, the first elastic element 235 is compressed and provides damping. When button 22 is pressed again, the third end 233 of the snap 23 slides along the beginning of the second segment 2223 of the sliding portion 222 and reaches the end of the second segment 2223. The second segment 2223 is a horizontal segment. At this time, the first elastic element 235 does not provide damping. The second elastic element 32 provides damping, and the damping change when pressing the button 22 is small, making it difficult to identify the state of the button 22. A top rod 24 is provided between the button 22 and the spring bar 31 of the watch strap, and a third elastic element 241 is sleeved on the top rod 24. Both the second elastic element 32 and the third elastic element 241 provide damping, which greatly increases the force required to press the button 22 again, making it easier to distinguish the state of the button 22. This effectively prevents the length adjustment structure of the watch strap 3 from accidentally entering the third state from the second state, improving the convenience of use and enhancing the user's cognitive ability.

[0081] Furthermore, a gap is left between the abutting part 223 and the push rod 24. The module body 21 is also provided with a second abutting block 214. The second abutting block 214 is disposed between the push rod 24 and the button 22. The abutting part 223 is adapted to pass through the second abutting block 214 and abut against the end face of the push rod 24. After pressing the button 22 again, the end of the sliding part 222 of the button 22 abuts against the second abutting block 214. At this time, the spring bar 31 of the watch strap completely leaves the third opening 216. When the button 22 is released, the push rod 24 moves in the opposite direction, so that the end of the push rod 24 near the abutting part 223 abuts against the second abutting block 214.

[0082] In this embodiment, in the first state, the third elastic member 241 pushes the end of the push rod 24 close to the abutting part 223 to abut against the second abutting block 214, so as to avoid the third elastic member 241 interfering with the initial press of the button 22.

[0083] Specifically, a third elastic element 241 is fitted onto the end of the push rod 24 furthest from the button 22. The third elastic element 241 is positioned between the push rod 24 and the inner wall of the movable lug module 2. The diameter of the third opening 216 is smaller than the diameter of the second opening 213. The third elastic element 241 is fitted onto the end of the push rod 24 near the third opening 216, allowing the tail end of the push rod 24 to pass through the third opening 216, and the head end of the push rod 24 to abut against the second abutting block 214 of the module body 21. When the button 22 is released, the third elastic element 241 pushes the push rod 24 to abut against the second abutting block 214. The push rod 24 and the watch strap spring bar 31 maintain a gap under the elastic force of the third elastic element 241. The button 22 and the push rod 24 also maintain a gap under the action of the first elastic element 235. The third elastic element 241 includes, but is not limited to, a compression spring.

[0084] It is worth noting that there can be no gap between the other end of the top rod 24 and the spring bar 31 of the watch strap; simply increase the gap between the abutment part 223 and the top rod 24.

[0085] Further, refer to Figure 5 The button 22 is also provided with a first abutting member 224, and the module body 21 is also provided with a first abutting block 215. When the end of the sliding part 222 of the button 22 abuts against the second abutting block 214, the first abutting member 224 abuts against the first abutting block 215.

[0086] In this embodiment, when the button 22 is in the third state, the first abutting member 224 abuts against the first abutting block 215 to prevent the button 22 from re-entering the first opening 2111. This would cause the pressing part 221 of the button 22 to fully enter the first opening 2111 and abut against the inner wall of the first opening 2111, making the button 22 unable to reset and causing a malfunction in the watch strap adjustment structure.

[0087] Specifically, the first abutting member 224 abuts against the first abutting block 215, so that the button 22 no longer needs to enter the first opening 2111. The pressing part 221 of the button 22 is exposed outside the first opening 2111, which makes it easy for the button 22 to be reset under the action of the third elastic member 241 and the first elastic member 235, thus avoiding the risk of the button 22 getting stuck.

[0088] Furthermore, the present invention provides a smartwatch, including the strap adjustment structure, main unit 4, and strap 3 as described in any of the above embodiments. The main unit 4 is mounted on the top of the base 1 of the strap adjustment structure; the strap 3 is mounted on the movable lug module 2 of the strap adjustment structure; when the button 22 of the strap adjustment structure is pressed for the first time, the movable lug module 2 can move on the base 1 to adjust the wearing length of the strap 3; when the button 22 is pressed for the second time, the movable lug module 2 can be separated from the strap 3.

[0089] In this embodiment, the main unit 4 is fixed on the top of the base 1, and the watch strap adjustment structure is fixed on the bottom of the base 1. The main unit 4 and the watch strap adjustment structure do not interfere with each other, so that the watch strap adjustment structure does not affect the installation and use of the main unit 4, thereby increasing the practicality of the smart watch strap 3.

[0090] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
