Description

Technical Field

[0001] This application relates to the field of wearable device technology, and more particularly to an adjustable watch strap, watch band, and wearable device. Background Technology

[0002] Modern smartwatches now feature enhanced health monitoring capabilities, capable of real-time monitoring of vital physiological indicators such as heart rate, blood pressure, and blood oxygen saturation. They can also provide in-depth analysis of sleep quality, collecting physiological and environmental data from various sensors. To ensure accurate capture and identification of this physiological data, close contact with the skin has become a crucial design element for smartwatches.

[0003] In existing technologies, the length adjustment of watch strap links in smart wearable devices relies on spring bars. During operation, users need to manually shorten or lengthen the spring bars and align them with different slots on the strap link to adjust the length and thus make minor adjustments to the strap size. However, in practical use, this method is cumbersome and inconvenient because each adjustment requires precise manual alignment of the spring bars with the slots, negatively impacting the user experience. Summary of the Invention

[0004] This application discloses an adjustable watch strap, watch band, and wearable device that enables the watch strap to switch between an extended state and a retracted state without the need for additional tools, thus improving ease of use. When the locking element is unlocked, the watch strap will automatically retract under the action of the reset element, avoiding the trouble of manual operation and ensuring the accuracy and stability of the retracted watch strap.

[0005] To achieve the above objectives, this application discloses an adjustable granulation, comprising:

[0006] The watch tick body has a first connecting part for connecting with the watch lug or other watch ticks, and the watch tick body is provided with a locking part.

[0007] The telescopic lug is slidably connected to the watch lug body along a first direction. The telescopic lug has an elongated state and a contracted state. The end of the telescopic lug away from the watch lug body has a second connecting part, which is used to connect with the watch lug or other watch lugs.

[0008] A locking member is movably disposed on the telescopic piece. The locking member has a locked state and an unlocked state. When the telescopic piece is in the extended state, the locking member can cooperate with the locking part to keep the telescopic piece in the extended state.

[0009] A reset member is disposed between the watch grain body and the telescopic grain. When the locking member is in the unlocked state, the reset member can drive the telescopic grain to move along the first direction and close to the watch grain body, so that the telescopic grain is reset to the contracted state.

[0010] In one possible implementation, the reset element includes a magnetic element for applying a magnetic force to the stretching particle toward the contracted state.

[0011] In one possible implementation, the surface grain body includes a mounting groove disposed toward the telescopic grain, the telescopic grain having an extension that is arranged opposite to the mounting groove along the thickness direction of the telescopic grain;

[0012] The magnetic component includes a first magnetic component and a second magnetic component. The first magnetic component is disposed on the surface of the extension facing the mounting groove, and the second magnetic component is disposed on the surface of the mounting groove facing the extension. When the telescopic particle is in the contracted state, the first magnetic component and the second magnetic component are arranged with opposite poles facing each other.

[0013] In one possible implementation, when the stretching particle is in the elongated state, the first magnetic element and the second magnetic element partially overlap along the thickness direction of the stretching particle.

[0014] In one possible implementation, the first N pole and the first S pole of the first magnetic element are arranged side by side along the first direction, and the second N pole and the second S pole of the second magnetic element are arranged side by side along the first direction. When the stretching particle is in the contracted state, the first N pole and the second S pole are arranged opposite to each other, and the first S pole and the second N pole are arranged opposite to each other. When the stretching particle is in the elongated state, along the thickness direction of the stretching particle, a portion of the first N pole coincides with the first S pole, and another portion of the first N pole coincides with the first N pole.

[0015] In one possible implementation, the adjustable tab further includes a first elastic element disposed between the telescopic tab and the locking element, the first elastic element being used to apply an elastic force to the locking element toward the locked state;

[0016] The mounting groove includes a first groove wall extending along the first direction, and the locking part includes a locking hole provided on the first groove wall. When the telescopic particle is in the contracted state, the locking member is stopped by the first groove wall, so that the first elastic member is compressed and the locking member is in the unlocked state. When the telescopic particle is in the extended state, the locking member corresponds to the locking hole, so that the locking member can be inserted into the locking hole under the restoring force of the elastic member and be in the locked state.

[0017] In one possible implementation, the locking member is movable along a second direction between the locked state and the unlocked state, the second direction being perpendicular to the first direction;

[0018] The adjustable watch grain also includes an operating member, which is slidably disposed within the watch grain body along the second direction. The operating member includes a pushing part, which is slidably engaged with the locking hole along the second direction.

[0019] In one possible implementation, the pushing portion extends along the thickness direction of the telescopic grain and has a first stop portion, and the locking hole has a second stop portion. Along the second direction, the first stop portion is close to the first groove wall relative to the second stop portion. The first stop portion and the second stop portion are arranged opposite to each other along the second direction to prevent the operating member from disengaging from the grain body.

[0020] In one possible implementation, the operating element further includes a locking protrusion, and the watch tick body is also provided with a locking groove. The locking protrusion and the locking groove slide in a second direction. The locking protrusion extends along the first direction with a third stop portion. The locking groove is provided with a fourth stop portion. Along the second direction, the third stop portion is close to the first groove wall relative to the fourth stop portion. The third stop portion and the fourth stop portion are arranged opposite to each other along the second direction to prevent the operating element from disengaging from the watch tick body.

[0021] In one possible implementation, the adjustable tab further includes a second elastic element disposed between the operating member and the tab body, the second elastic element being used to apply an elastic force to the operating member moving along the second direction and away from the tab body.

[0022] In one possible implementation, the watch grain body is provided with a fifth stop portion, and the telescopic grain includes a stop protrusion. Along the first direction, the stop protrusion is close to the first connecting portion relative to the fifth stop portion. The stop protrusion and the fifth stop portion are correspondingly arranged along the first direction. When the telescopic grain is in an extended state, the stop protrusion and the fifth stop portion abut against each other along the first direction to prevent the telescopic grain from detaching from the watch grain body.

[0023] In one possible implementation, the telescopic particle is provided with a fixed sleeve with an opening facing the first sidewall, the fixed sleeve extends along the second direction, the locking member slides with the fixed sleeve along the second direction, the first elastic member is disposed between the locking member and the fixed sleeve, and when the locking member is in the locked state, the locking member extends out of the fixed sleeve.

[0024] This application also discloses a watch strap including the adjustable watch beads described in any of the above claims.

[0025] This application also discloses a wearable device, including a device body connected to a watch strap on the device body, the watch strap including the watch strap described above.

[0026] Compared with the prior art, the beneficial effects of this application are as follows:

[0027] In the adjustable watch beads, watch straps, and wearable devices provided in this application, the adjustable watch beads include a watch bead body and a telescopic bead. The telescopic bead and the watch bead body are slidably connected along a first direction. In the extended state, the telescopic bead extends out of the watch bead body, increasing the overall length of the watch bead. In the contracted state, the telescopic bead moves closer to the watch bead body, shortening the length of the watch bead. Specifically, the watch bead body has a locking part along the first direction. A locking member is movably disposed on the telescopic bead and can move between a locked state and an unlocked state. In the locked state, the locking member cooperates with the locking part on the watch bead body to fix the telescopic bead in the extended state, preventing it from retracting. A reset member is disposed between the watch bead body and the telescopic bead. When the locking member is in the unlocked state, the locking member separates from the locking part, releasing the fixation of the telescopic bead, allowing the telescopic bead to move freely. The reset member generates a corresponding force, driving the telescopic bead to move along the first direction and closer to the watch bead body, thereby automatically resetting the telescopic bead to the contracted state.

[0028] The adjustable watch links of this application can be adjusted through the elongation and contraction function of the telescopic links. Users can adjust the telescopic links to the extended or contracted state according to their wrist size or wearing needs, enabling more precise adjustment of the watch band length, ensuring a good fit between the watch sensor and the skin, and improving the accuracy of data collection. The watch link body and the telescopic links are respectively provided with a first connecting part and a second connecting part, which can be connected to the lugs or other watch links, making it compatible with different styles of watches and having good versatility. Furthermore, the locking and resetting mechanisms simplify the fixing and unlocking of the telescopic link. Users only need to operate the locking mechanism to easily switch the telescopic link between its extended and retracted states without the need for additional tools, thus improving ease of use. When the locking mechanism is unlocked, the telescopic link automatically retracts under the action of the resetting mechanism, avoiding the hassle of manual operation and ensuring the accuracy and stability of the telescopic link's retraction. The cooperation between the locking mechanism and the locking part effectively ensures the stability of the telescopic link in its extended state. Even under certain external forces, the telescopic link will not easily retract, ensuring the stability of the strap length and improving the watch's reliability. Attached Figure Description

[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] In this application, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0052] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0053] Modern smartwatches now feature enhanced health monitoring capabilities, capable of real-time monitoring of vital physiological indicators such as heart rate, blood pressure, and blood oxygen saturation. They can also provide in-depth analysis of sleep quality, collecting physiological and environmental data from various sensors. To ensure accurate capture and identification of this physiological data, close contact with the skin has become a crucial design element for smartwatches.

[0054] In existing technologies, the length adjustment of watch strap links in smart wearable devices relies on spring bars. During operation, users need to manually shorten or lengthen the spring bars and align them with different slots on the strap link to adjust the length and thus make minor adjustments to the strap size. However, in practical use, this method is cumbersome and inconvenient because each adjustment requires precise manual alignment of the spring bars with the slots, negatively impacting the user experience.

[0055] In view of this, some embodiments of this application provide an adjustable watch strap, watch band, and wearable device that enables the watch strap to switch between an extended state and a retracted state without the need for additional tools, thus improving ease of use. When the locking element is unlocked, the watch strap will automatically retract under the action of the reset element, avoiding the trouble of manual operation and ensuring the accuracy and stability of the retraction of the watch strap.

[0056] The present application will be described in detail below through specific embodiments:

[0057] The adjustable granules in the embodiments of this application, such as Figures 1-13 As shown, an adjustable granule includes:

[0058] Watch tick body 10, watch tick body 10 has a first connecting part 11, the first connecting part 11 is used to connect with watch lugs or other watch ticks, and watch tick body 10 is provided with a locking part 12.

[0059] The telescopic grain 20 is slidably connected to the watch grain body 10 along a first direction. The telescopic grain 20 has an elongated state and a contracted state. The end of the telescopic grain 20 away from the watch grain body 10 has a second connecting part 21, which is used to connect with the watch lug or other watch grains.

[0060] The locking member 30 is movably disposed on the telescopic particle 20. The locking member 30 has a locked state and an unlocked state. When the telescopic particle 20 is in the extended state, the locking member 30 can cooperate with the locking part 12 to keep the telescopic particle 20 in the extended state.

[0061] The reset member 40 is located between the watch bead body 10 and the telescopic bead 20. When the locking member 30 is in the unlocked state, the reset member 40 can drive the telescopic bead 20 to move along the first direction and close to the watch bead body 10, so that the telescopic bead 20 is reset to the contracted state.

[0062] The adjustable face grain provided in this application embodiment includes a face grain body 10 and a telescopic grain 20. The telescopic grain 20 is slidably connected to the face grain body 10 along a first direction. In the extended state, the telescopic grain 20 extends out of the face grain body 10, increasing the length of the entire face grain. In the contracted state, the telescopic grain 20 moves closer to the face grain body 10, shortening the length of the face grain. Specifically, the watch bead body 10 is provided with a locking part 12 along the first direction, and a locking member 30 is movably disposed on the telescopic bead 20 and can move between the locked state and the unlocked state. In the locked state, the locking member 30 cooperates with the locking part 12 on the watch bead body 10 to fix the telescopic bead 20 in the extended state and prevent it from retracting. The reset member 40 is disposed between the watch bead body 10 and the telescopic bead 20. When the locking member 30 is in the unlocked state, the locking member 30 separates from the locking part 12, releases the fixation on the telescopic bead 20, and allows the telescopic bead 20 to move freely. The reset member 40 generates a corresponding force, which drives the telescopic bead 20 to move along the first direction and close to the watch bead body 10, thereby causing the telescopic bead 20 to automatically reset to the contracted state.

[0063] The adjustable watch links of this application can be adjusted through the elongation and contraction function of the telescopic links 20. Users can adjust the telescopic links 20 to the extended or contracted state according to their wrist size or wearing needs, enabling more precise adjustment of the watch band length, ensuring a good fit between the watch sensor and the skin, and improving the accuracy of data collection. The watch link body 10 and the telescopic links 20 are respectively provided with a first connecting part 11 and a second connecting part 21, which can be connected to the lugs or other watch links, adapting to different styles of watches and having good versatility. Furthermore, the locking member 30 and the reset member 40 make the fixing and unlocking of the telescopic link 20 simple and easy. Users only need to operate the locking member 30 to easily switch the telescopic link 20 between the extended and retracted states without the need for additional tools, thus improving ease of use. When the locking member 30 is unlocked, the telescopic link 20 will automatically retract under the action of the reset member 40, avoiding the trouble of manual operation and ensuring the accuracy and stability of the retraction of the telescopic link 20. The cooperation between the locking member 30 and the locking part 12 can effectively ensure the stability of the telescopic link 20 in the extended state. Even if subjected to a certain external force, the telescopic link 20 will not easily retract, ensuring the stability of the strap length and improving the reliability of the watch.

[0064] In the diagram, the X direction is the first direction, the Y direction is the second direction, and the Z direction is the thickness direction of the stretching particle 20.

[0065] Specifically, in some embodiments, such as Figure 2 and Figure 5 As shown, the reset member 40 includes a magnetic member 41, which is used to apply a magnetic force to the stretching particle 20 toward the contracted state.

[0066] A magnetic component 41 is disposed between the watch bead body 10 and the telescopic bead 20. When the telescopic bead 20 is in an extended state, the locking component 30 and the locking part 12 cooperate to fix the telescopic bead 20. At this time, there is still a magnetic attraction between the magnetic components 41, but due to the locking effect of the locking component 30, the telescopic bead 20 will not retract under the action of magnetic force. When the locking component 30 switches from the locked state to the unlocked state, releasing the locking of the telescopic bead 20, the attraction between the magnetic components 41 will immediately act on the telescopic bead 20, pulling the telescopic bead 20 along the first direction and close to the watch bead body 10, so that the telescopic bead 20 returns to the retracted state. The magnetic component 41 uses magnetic force to achieve the retraction of the telescopic bead 20. The force transmission is non-contact, and the magnetic force is continuous and uniform, avoiding direct contact and friction between mechanical parts, reducing wear and energy loss. During the process of retraction, the telescopic bead 20 can move smoothly to the retracted state.

[0067] In other embodiments, the reset member 40 may also be implemented by means of a mechanical reset member 40 such as a spring.

[0068] Furthermore, in one possible implementation, such as Figure 2 and Figure 12 As shown, the surface grain body 10 includes a mounting groove 13 disposed toward the telescopic grain 20, the telescopic grain 20 has an extension 22, and the extension 22 and the mounting groove 13 are arranged opposite to each other along the thickness direction of the telescopic grain 20.

[0069] like Figure 2 As shown, the magnetic component 41 includes a first magnetic component 411 and a second magnetic component 412. The first magnetic component 411 is disposed on the surface of the extension 22 facing the mounting groove 13, and the second magnetic component 412 is disposed on the surface of the mounting groove 13 facing the extension 22. When the telescopic particle 20 is in a contracted state, the first magnetic component 411 and the second magnetic component 412 are arranged with opposite poles facing each other.

[0070] Since the first magnetic element 411 and the second magnetic element 412 are opposite poles when the telescopic granulation piece 20 is in the contracted state, the attraction between them ensures that the telescopic granulation piece 20 reliably returns to the contracted state after the locking element 30 is unlocked. By placing the first magnetic element 411 and the second magnetic element 412 on the opposing surfaces of the extension 22 and the mounting groove 13, the space between the granulation piece body 10 and the telescopic granulation piece 20 is fully utilized, making the entire adjustable granulation piece structure more compact. Simultaneously, the mating structure of the mounting groove 13 and the extension 22 provides precise guidance for the sliding of the telescopic granulation piece 20. Under the magnetic force generated by the magnetic element 41, the telescopic granulation piece 20 can move accurately along the direction of the mounting groove 13, avoiding deviation or jamming during the reset process and ensuring the smoothness and accuracy of the telescopic granulation piece 20's movement.

[0071] In some embodiments, such as Figure 5 As shown, when the stretching particle 20 is in an elongated state, the first magnetic element 411 and the second magnetic element 412 partially overlap along the thickness direction of the stretching particle 20.

[0072] When the telescopic particle 20 is in an elongated state, the first magnetic element 411 and the second magnetic element 412 partially overlap and generate a certain magnetic attraction. When the locking element 30 is unlocked, the telescopic particle 20 can be reset more quickly, improving the reset response speed. The magnetic attraction between the first magnetic element 411 and the second magnetic element 412 can continue to exist and gradually increase. As the telescopic particle 20 contracts, the overlapping area gradually increases, and the magnetic attraction is also strengthened accordingly, providing a continuous and gradually increasing driving force for the reset of the telescopic particle 20, ensuring the stability and continuity of the reset process, and also reducing the possibility of reset function failure.

[0073] In this embodiment, as Figure 11 and Figure 13 As shown, the first N pole 4111 and the first S pole 4112 of the first magnetic element 411 are arranged side by side along the first direction, and the second N pole 4121 and the second S pole 4122 of the second magnetic element 412 are arranged side by side along the first direction. When the stretching particle 20 is in a contracted state, the first N pole 4111 and the second S pole 4122 are arranged opposite to each other, and the first S pole 4112 and the second N pole 4121 are arranged opposite to each other. When the stretching particle 20 is in an extended state, along the thickness direction of the stretching particle 20, a part of the first N pole 4111 overlaps with the first S pole 4112, and another part of the first N pole 4111 overlaps with the first N pole 4111.

[0074] By arranging the two magnetic poles of the first magnetic element 411 and the second magnetic element 412 along the first direction, when the stretching particle 20 is in a contracted state, the first N pole 4111 and the second S pole 4122 are positioned opposite each other, and the first S pole 4112 and the second N pole 4121 are positioned opposite each other. At this time, the attraction between the first magnetic element 411 and the second magnetic element 412 is at its maximum, which can firmly hold the stretching particle 20 in the contracted state. When the stretching particle 20 is in an elongated state, along the thickness direction of the stretching particle 20, a portion of the first N pole 4111 overlaps with the second S pole 4122, and another portion of the first N pole 4111 overlaps with the second N pole 4121. This partially overlapping magnetic pole distribution results in both attractive and repulsive forces between the magnetic elements 41. The portion where the first N pole 4111 overlaps with the second S pole 4122 generates an attractive force, while the portion where the first N pole 4111 overlaps with the second N pole 4121 generates a repulsive force.

[0075] In the contracted state, the attraction between opposite magnetic poles ensures that the stretching particle 20 remains stably in the contracted position. In the extended state, the repulsive force generated by the partially overlapping like magnetic poles allows a small gap to be created between the surface particle body 10 and the stretching particle 20. The attraction generated by the partially overlapping opposite magnetic poles quickly takes effect, causing the stretching particle 20 to return from the extended state to the contracted state. Moreover, because the attraction between opposite poles is greater in the contracted state, it ensures that the stretching particle 20 returns to its original position quickly and accurately, improving the efficiency and reliability of the return process.

[0076] It needs to be explained that magnetic component 41 is a magnetic object capable of generating a magnetic field. The N pole (north pole) and S pole (south pole) are two key concepts describing the magnetic field characteristics of the magnetic component, together forming the basic polarity structure of the magnet. N pole (north pole): Under the influence of the Earth's magnetic field, the end of a magnet that can rotate freely, pointing north, is defined as the N pole. From a microscopic perspective, the N pole is the starting point of magnetic field lines. Magnetic field lines are virtual lines used to visually describe the distribution of the magnetic field. Starting from the N pole, passing through external space, and finally returning to the S pole, they form a closed loop. S pole (south pole): Similarly, for a magnet that can rotate freely in the Earth's magnetic field, the end pointing south is the S pole. It is the returning point of the magnetic field lines, and together with the N pole, it forms the complete cycle of the magnet's magnetic field. When the N pole of one magnet approaches the S pole of another magnet, they will attract each other. If the N poles of two magnets approach each other, or the two S poles approach each other, they will repel each other.

[0077] In the elongated state, along the first direction, the distance between the overlapping portions of the first N pole 4111 and the second N pole 4121 is greater than the distance between the overlapping portions of the first N pole 4111 and the second S pole 4122.

[0078] Specifically, such as Figure 4 As shown, the adjustable tab also includes a first elastic element (not shown in the figure), which is disposed between the telescopic tab 20 and the locking element 30. The first elastic element is used to apply an elastic force to the locking element 30 to the locked state.

[0079] like Figure 4 and Figure 13 As shown, the mounting groove 13 includes a first groove wall 131 extending along a first direction, and the locking part 12 includes a locking hole 121 provided on the first groove wall 131. When the telescopic particle 20 is in a contracted state, the locking member 30 is stopped by the first groove wall 131, so that the first elastic member is compressed and the locking member 30 is in an unlocked state. When the telescopic particle 20 is in an extended state, the locking member 30 corresponds to the locking hole 121, so that the locking member 30 can be inserted into the locking hole 121 under the restoring force of the elastic member and be in a locked state.

[0080] The first elastic element is disposed between the telescopic particle 20 and the locking element 30. When the telescopic particle 20 is in the contracted state, the locking element 30 is stopped by the first groove wall 131. At this time, the first elastic element is compressed, and the locking element 30 is in the unlocked state. When the telescopic particle 20 is pulled into the extended state, the locking element 30 corresponds to the locking hole 121, the stop of the locking element 30 is removed, and the restoring force of the first elastic element pushes the locking element 30 into the locking hole 121, so that the locking element 30 is in the locked state, thereby fixing the telescopic particle 20 in the extended position.

[0081] The presence of the first elastic element gives the locking element 30 a tendency to move automatically to the locked state. When the telescopic piece 20 is pulled until the locking element 30 corresponds to the locking hole 121, the locking element 30 will automatically insert into the locking hole 121 under the action of the elastic element's restoring force, thus achieving automatic locking. The operation is simple; the user only needs to stretch the telescopic piece 20 to the appropriate position, and locking can be completed without any additional complicated operations, which improves the convenience of use.

[0082] In some embodiments, such as Figure 9 As shown, the locking member 30 can move between a locked state and an unlocked state along a second direction, which is perpendicular to the first direction.

[0083] The adjustable watch grain also includes an operating member 60, which is slidably disposed within the watch grain body 10 along the second direction. The operating member 60 includes a pushing part 61, which is slidably engaged with the locking hole 121 along the second direction.

[0084] When it is necessary to unlock the telescopic link 20 from its extended state, the user can operate the operating member 60 to slide it along the second direction. The pushing part 61 of the operating member 60 moves accordingly and pushes the locking member 30, overcoming the elastic force of the first elastic member, causing the locking member 30 to disengage from the locking hole 121 and enter the unlocked state. At this time, the telescopic link 20 can retract under the action of the reset member 40. The design of the operating member 60 provides the user with a convenient way to unlock the telescopic link 20. Simply pushing the operating member 60 to slide in the second direction can easily disengage the locking member 30 from the locking hole 121, thus unlocking the telescopic link 20. The operation is simple and intuitive, requiring no complicated actions or tools, improving the efficiency and convenience of adjusting the watch strap length.

[0085] In other embodiments, the locking member 30 may extend beyond the watch grain body 10, and adjustment may be achieved directly through the locking member 30.

[0086] In some embodiments, such as Figure 4 As shown, the pusher 61 extends along the thickness direction of the telescopic pellet 20 and has a first stop 611. The locking hole 121 is provided with a second stop 1211. Along the second direction, the first stop 611 is close to the first groove wall 131 relative to the second stop 1211. The first stop 611 and the second stop 1211 are arranged opposite to each other along the second direction to prevent the operating member 60 from disengaging from the pellet body 10.

[0087] When the operating member 60 slides in the second direction within the watch body 10, the first stop 611 gradually moves away from the second stop 1211. When the operating member 60 needs to retract after unlocking the locking member 30, the first stop 611 will contact the second stop 1211 when the operating member 60 slides away from the watch body 10 to a certain position, preventing the operating member 60 from continuing to slide and thus preventing the operating member 60 from detaching from the watch body 10. This greatly improves the reliability of the entire structure and ensures that the product can work stably for a long time.

[0088] Furthermore, such as Figure 6 and Figure 9 As shown, the operating member 60 also includes a locking protrusion 62, and the watch tick body 10 is also provided with a locking groove 14. The locking protrusion 62 and the locking groove 14 slide in a second direction. The locking protrusion 62 extends a third stop portion 621 in a first direction. The locking groove 14 is provided with a fourth stop portion 141. In the second direction, the third stop portion 621 is close to the first groove wall 131 relative to the fourth stop portion 141. The third stop portion 621 and the fourth stop portion 141 are arranged opposite to each other in the second direction to prevent the operating member 60 from disengaging from the watch tick body 10.

[0089] When the operating member 60 slides along the second direction, the third stop 621 gradually moves away from the fourth stop 141. When the operating member 60 unlocks the locking member 30 and needs to retract, as the operating member 60 slides away from the watch bead body 10 to a certain position, the third stop 621 contacts the fourth stop 141, preventing the operating member 60 from sliding further and thus preventing it from detaching from the watch bead body 10. The third stop 621 on the locking protrusion 62 and the fourth stop 141 on the locking groove 14 provide double protection against the operating member 60 detaching from the watch bead body 10, further improving the reliability of the structure and greatly reducing the risk of the operating member 60 detaching from the watch bead body 10. At the same time, the first stop 611 extends along the thickness direction of the telescopic bead 20, and the third stop 621 extends along the first direction. Therefore, the stopping of the operating member 60 comes from two directions, making the stopping effect on the operating member 60 more reliable and stable.

[0090] In some embodiments, such as Figure 10 As shown, the adjustable tab also includes a second elastic element 50, which is disposed between the operating member 60 and the tab body 10. The second elastic element 50 is used to apply an elastic force to the operating member 60 that moves along a second direction away from the tab body 10.

[0091] The operating component 60 unlocks the telescopic nut 20 by pushing the locking component 30 through the pushing part 61. The user pushes the operating component 60 to compress the second elastic element 50. After unlocking, the second elastic element 50 pushes the operating component 60 back to its original position. During the reset process, the third stop 621, the fourth stop 141, the first stop 611, and the second stop 1211 limit the range of motion of the operating component 60, ensuring that the operating component 60 does not detach from the nut body 10 during the reset process, thus guaranteeing the stability and reliability of the entire structure. After unlocking the telescopic nut 20, the user does not need to manually reset the operating component 60; it will automatically return to its initial position under the action of the second elastic element 50. This not only improves the convenience of operation but also makes the operation process smoother, enhancing the user experience.

[0092] In some other embodiments, the two ends of the first elastic member are fixedly connected to the operating member 60 and the surface pellet body 10 respectively, and the first, second, third and fourth stop portions 141 may not be provided additionally.

[0093] The first elastic element and the second elastic element 50 can be implemented in various ways, such as springs, elastic rubber strips, or elastic ropes. In this embodiment, both the first elastic element and the second elastic element 50 are springs.

[0094] In some embodiments, such as Figure 7 As shown, the watch grain body 10 is provided with a fifth stop portion 15, and the telescopic grain 20 includes a stop protrusion 23. Along the first direction, the stop protrusion 23 is close to the first connecting portion 11 relative to the fifth stop portion 15. The stop protrusion 23 and the fifth stop portion 15 are correspondingly arranged along the first direction. When the telescopic grain 20 is in the extended state, the stop protrusion 23 and the fifth stop portion 15 abut against each other along the first direction to prevent the telescopic grain 20 from detaching from the watch grain body 10.

[0095] When the telescopic stud 20 is pulled into its extended state, the stop protrusion 23 gradually approaches the fifth stop portion 15. As the telescopic stud 20 continues to extend, when it reaches its maximum extension position, the stop protrusion 23 and the fifth stop portion 15 correspond to and abut against each other along the first direction. Due to the blocking effect of the two, the telescopic stud 20 cannot continue to extend outward along the first direction, thus effectively preventing the telescopic stud 20 from detaching from the watch bead body 10. Even if the locking member 30 and the locking hole 121 are not locked, there is no need to worry about the telescopic stud 20 accidentally detaching, making it more reassuring to adjust the watch strap length and improving the user experience and satisfaction.

[0096] In some embodiments, such as Figure 10As shown, the telescopic particle 20 is provided with a fixed sleeve 24 with an opening facing the first side wall. The fixed sleeve 24 extends along the second direction. The locking member 30 and the fixed sleeve 24 slide in the second direction. The first elastic member is provided between the locking member 30 and the fixed sleeve 24. When the locking member 30 is in the locked state, the locking member 30 extends out of the fixed sleeve 24.

[0097] The fixed sleeve 24 provides a precise sliding guide for the locking member 30, enabling it to move accurately to the locked or unlocked position in the second direction. This ensures the accuracy of the adjustable watch links switching between extended and retracted states, improving the convenience and reliability of adjusting the watch strap length for the user. The fixed sleeve 24 allows the locking member 30 and the first elastic element to be integrated inside the telescopic link 20, forming a compact structural unit. This not only reduces the overall volume of the adjustable watch links but also improves the strength and stability of the structure. Because the locking member 30 moves precisely and its elastic return is stable, the user experiences a smooth and fluid operation when manipulating the adjustable watch links.

[0098] In other embodiments, the first elastic element may also be directly disposed between the locking element 30 and the telescopic particle 20.

[0099] This application also discloses a watch strap including adjustable watch beads. This application further discloses a wearable device including a device body and a watch strap connected to the device body. The adjustable watch beads in the watch strap and the wearable device are the aforementioned adjustable watch beads. Therefore, the watch strap and wearable device in this embodiment have substantially the same technical effects as the aforementioned adjustable watch beads. Since the technical effects of the adjustable watch beads have been fully explained, they will not be repeated here.

[0100] It should be explained that the adjustable watch bit in this application can be any watch bit, either the top or any watch bit in the middle of the watch band. When the adjustable watch bit is the top watch bit, the first connecting part 11 is connected to the lug of the device body, and the second connecting part 21 is connected to the end watch bit of the watch band near the device body. When the adjustable watch bit is any watch bit in the middle of the watch band, both the first connecting part 11 and the second connecting part 21 are connected to other watch bits in the watch band. Furthermore, the wearable device can be a smartwatch, a smart bracelet, etc., and this application is not limited to any of these.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
