Description

Technical Field

[0001] This invention relates to the field of wearable device technology, and more particularly to a watch buckle component and a smartwatch. Background Technology

[0002] With the rapid development of technology, various smart wearable devices are permeating all aspects of people's lives, bringing tremendous changes to their daily experiences. Wearable devices are not merely hardware devices; they achieve their powerful functions through software support, data interaction, and cloud interaction. Their applications are very broad, including healthcare, fitness, and communication. For example, watches are no longer limited to simply telling time. By embedding intelligent hardware and running a smartphone operating system connected to the network, they can perform various functions such as making calls, sending text messages, emails, viewing photos, and listening to music and videos. Smartwatches are an extension and expansion of smartphone functions, bringing great convenience to people's daily lives.

[0003] When wearing a smartwatch, the case should fit snugly against the wrist for a secure fit and improved user experience. However, traditional watch bands generally come in two types: buckle bands and chain bands. Buckle bands require disassembly and reassembly for length adjustments, a cumbersome process that results in a poor user experience. Chain bands, on the other hand, have fixed-length individual links, requiring users to purchase additional parts or remove excess links for adjustments, a complex process that may not yield the desired length, impacting the performance of the smartwatch. Furthermore, both methods pose risks of pinching skin during adjustment and can be difficult for children, creating a safety hazard.

[0004] Therefore, how to improve the technical defects existing in the prior art has always been a problem that ordinary people skilled in the art need to solve. Summary of the Invention

[0005] The purpose of this invention is to provide a watch buckle component and a smartwatch. Users only need to press and simultaneously rotate the knob to adjust the length of the watch strap according to their own comfort during wearing. Releasing the knob will automatically lock the length of the watch strap, which can greatly simplify the user's adjustment steps. It is simple to operate and highly safe.

[0006] The technical solution provided by this invention is as follows:

[0007] In a first aspect, the present invention provides a watch buckle member comprising:

[0008] The watch buckle body is connected to the main unit;

[0009] The buckle body has a slide extending into it on the side away from the main unit;

[0010] Adjustment components include a knob, a spring element, a rack, a toothed disc, a locking element, and a strap connecting piece;

[0011] The knob is located on the outside of the buckle body and is used to fix the gear plate inside the slide.

[0012] The elastic element allows the knob to be operablely pressed and rebounded;

[0013] When pressed, the toothed disc and the rack mesh, and the knob rotates to move the rack relative to the toothed disc, so that the strap connecting beads drive the strap to extend and retract.

[0014] In the springback state, the locking element and the toothed disc engage to limit the rotation of the toothed disc, thereby locking the rack.

[0015] In some embodiments, the upper end of the buckle body is provided with a rotation position for accommodating the knob; and

[0016] The center of the rotating station is provided with a hole that leads to the slide rail;

[0017] The knob has a connecting portion that extends through the hole into the interior of the slide rail to engage with the gear plate, thereby fixing the gear plate inside the slide rail.

[0018] In some embodiments, the locking element includes a ratchet;

[0019] The ratchet is fixed inside the slide and is located directly above the toothed disc;

[0020] The ratchet has a first double-ring tooth on the side facing the toothed disc;

[0021] The toothed disc has a second double-ring tooth that matches the first double-ring tooth on the side facing the ratchet;

[0022] When the knob is in the spring-loaded state, the first double-ring teeth and the second double-ring teeth mesh to restrict the rotation of the gear plate, thereby locking the rack.

[0023] In some embodiments, the peripheral edge of the toothed disc is provided with annular teeth;

[0024] The rack is mounted on the watch strap connecting piece and is located inside the slide corresponding to the side position of the toothed disc;

[0025] During the rotation of the gear disk, the annular teeth mesh with the rack, thereby driving the rack to move back and forth along the slide rail.

[0026] In some embodiments, the thickness of the rack is greater than the thickness of the toothed disc, so that the toothed disc remains in contact with the rack during the switching of the knob from the pressed state to the spring-back state.

[0027] In some embodiments, the elastic element includes at least one compression spring;

[0028] The pressing spring is installed inside the rotating station to engage with the knob.

[0029] In some embodiments, the upper surface of the knob is truncated cone-shaped; and

[0030] The upper surface of the knob is provided with anti-slip texture.

[0031] In some embodiments, the buckle body has a host connector attached to the host on the side away from the strap connector.

[0032] In some embodiments, the buckle body has an isosceles trapezoidal block structure to connect the outline of the main unit and the watch strap.

[0033] In a second aspect, the present invention also provides a smartwatch, comprising:

[0034] The main unit, the watch strap, and the watch buckle member connected to the main unit and the watch strap to adjust the telescopic length of the watch strap relative to the main unit;

[0035] The buckle component is the buckle component described above.

[0036] The technical advantages of this invention are as follows:

[0037] In this patent, the user only needs to press and simultaneously rotate the knob to cause the gear plate to drive the rack in a back-and-forth motion, providing power for the strap connecting links to move forward or backward. This changes the distance between the strap connecting links and the buckle body, thus adjusting the strap length. When the user releases the pressure on the knob, the elastic element causes the knob to spring back, causing the gear plate and locking element to engage. Under the limiting action of the locking element, the gear plate cannot rotate on its own, and the gear plate and rack are still in a meshing state. Therefore, the locking element locks the rack, thereby locking the strap length and preventing the strap from being pulled in either direction. This greatly simplifies the user's strap adjustment process and provides high stability. Especially for children, it significantly improves the portability and safety of operation, preventing muscle injuries. Attached Figure Description

Detailed Implementation

[0052] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0053] To keep the drawings concise, each figure only schematically shows the parts relevant to the invention, and these do not represent the actual structure of the product. Furthermore, to facilitate understanding, in some figures, only one of components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0054] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0055] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0056] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0057] According to a specific embodiment provided by the present invention, such as Figures 1 to 4As shown, the present invention provides a watch buckle component 100 in a first aspect, which specifically includes a watch buckle body 1 and an adjustment component 2. The watch buckle body 1 is connected to a host computer, and a slide rail 11 extending into the side of the watch buckle body 1 away from the host computer is provided therein. The adjustment component 2 specifically includes a knob 21, an elastic element 22, a rack 23, a toothed disc 26, a locking element 24, and a watch strap connecting bead 25. The knob 21 is located outside the watch buckle body 1 and is used to fix the toothed disc 26 inside the slide rail 11. The elastic element 22 allows the knob 21 to be operably pressed and rebounded. In the pressed state, the toothed disc 26 and the rack 23 are engaged, and the knob 21 rotates to move the rack 23 relative to the toothed disc 26, so that the watch strap connecting bead 25 drives the watch strap 200 to perform telescopic movement. In the rebound state, the locking element 24 and the toothed disc 26 are engaged to limit the rotation of the toothed disc 26, thereby locking the rack 23.

[0058] In this embodiment, the user only needs to press and simultaneously rotate the knob 21 to cause the toothed disc 26 to drive the rack 23 to move back and forth in the front and back directions, providing power for the strap connecting piece 25 to move forward or backward. This changes the distance between the strap connecting piece 25 and the buckle body 1, thereby adjusting the length of the strap 200. When the user removes the pressure applied to the knob 21, the elastic element 22 will cause the knob 21 to rebound, causing the toothed disc 26 and the locking element 24 to engage. Under the limiting action of the locking element 24, the toothed disc 26 cannot rotate on its own, and the toothed disc 26 and the rack 23 are still in a meshing state. Therefore, the locking element 24 can lock the rack 23, thereby locking the length of the strap 200, making it impossible to pull the strap 200 in either direction. This greatly simplifies the user's adjustment steps for the strap 200 and provides high stability. Especially for children, it can greatly improve the portability and safety of children's operation, and will not cause muscle tissue to be pinched.

[0059] Of course, the present invention also provides a smartwatch in a second aspect, see [link to relevant documentation]. Figure 1 The smartwatch may specifically include a main unit, a watch strap 200, and a buckle member 100 provided in the first aspect of the invention. The buckle member 100 is connected to the main unit and the watch strap 200 to adjust the telescopic length of the watch strap 200 relative to the main unit, allowing the user to adjust the smartwatch to the most comfortable wearing size without removing the watch strap 200. This greatly improves the problem of children having difficulty wearing the watch and the potential safety hazards, ensuring that children will not pinch their skin tissue during the adjustment of the watch strap 200, thus enhancing safety.

[0060] Furthermore, traditional smartwatches typically use a buckle-style or separate chain-like strap, usually consisting of two straps connected to lugs at opposite ends of the watch face. A buckle is used between the two straps to allow the smartwatch to be worn. However, the buckle's location between the two straps results in a less aesthetically pleasing overall connection, affecting the visual experience. Moreover, the buckle structure is less stable, easily damaged, and cumbersome to operate, leading to a poor user experience. Most importantly, adjusting the strap length can easily pinch skin tissue, especially for children, making the wearing process difficult and posing a safety hazard. Therefore, in this embodiment, preferably, a single strap 200 is used, with one end connected to a lug on one end of the main unit and the other end connected to a lug on the other end of the main unit via a buckle component 100. The user only needs to operate the buckle component 100 to extend the strap 200 into a loop, and then place the user's hand on the strap 200 to wear the smartwatch on their wrist. By further manipulating the buckle component 100, that is, by rotating the knob 21 while it is pressed, the length of the watch strap 200 can be precisely adjusted according to personal comfort to tighten the watch strap 200, thus completing the wearing process. In this embodiment, by placing the buckle component 100 near the main unit, the watch strap 200 can be made into a one-piece structure, which is more aesthetically pleasing, easier to operate, and more stable, greatly improving the user experience. Of course, in this embodiment, the watch strap 200 can also be made into a split structure, that is, the two watch straps 200 can be connected by a traditional buckle, and one of the watch straps 200 can be connected to the main unit by the buckle component 100 provided in this embodiment. This can greatly enrich the application scenarios of smartwatches and meet the needs of more users. No specific limitation is made here, and any variation in structure is within the protection scope of this patent.

[0061] In order to ensure that the clasp component 100 can be fully connected to the outline structure of the main body and the watch strap 200, see [reference needed]. Figure 1 and Figure 2 Since the width of the main unit is greater than the width of the watch band 200, it is preferable to design the buckle body 1 as an isosceles trapezoidal block structure to connect the outline of the main unit and the watch band 200, thereby improving the overall aesthetics. Of course, since the sizes of different smartwatch models vary, the specific structure of the buckle body 1 can be flexibly set according to the actual product and is not limited to an isosceles trapezoidal block structure.

[0062] Furthermore, in this embodiment, see also... Figure 1 and Figure 2The buckle body 1 has a main unit connecting piece 15 on the side away from the strap connecting piece 25, which is connected to the main unit. The main unit connecting piece 15 is used to mate with the lugs of the main unit, and the strap connecting piece 25 is used to mate with the end of the strap 200, thus completing the assembly between the buckle component 100, the main unit, and the strap 200. The specific structure of the strap connecting piece 25 and the main unit connecting piece 15 is not specifically limited here, and can be flexibly set according to the contours of the strap 200 and the main unit, all of which are within the protection scope of this patent, and will not be described in detail here.

[0063] It is worth mentioning that, in this embodiment, the main unit connecting piece 15 can preferably be integrally formed with the watch buckle body 1, which can greatly improve the structural strength of the connection between the main unit and the watch buckle component 100. For example, the watch buckle body 1 and the main unit connecting piece 15 can be formed by plastic injection molding or molten metal cooling molding, both of which are within the protection scope of this patent and are not specifically limited here.

[0064] In this embodiment, see Figure 3 and Figure 4 By designing the knob 21 to be pressed before rotating, the user can be effectively prevented from accidentally touching the knob 21 or the knob 21 from being easily rotated due to external force during daily wear of the smartwatch, thus changing the length of the strap 200 and affecting the user's wearing experience. With this structure, the knob 21 is always in a pop-up state during daily work and life, ensuring that the gear 26 and the locking member 24 are always in a limited engagement state. Under the limiting action of the locking member 24, the knob 21 cannot rotate, thus ensuring that the gear 26 cannot rotate on its own. Furthermore, the gear 26 and the rack 23 are still engaged, so the locking member 24 locks the rack 23, thereby locking the length of the strap 200. This prevents the strap 200 from being pulled in either direction, ensuring a very comfortable wearing experience even after prolonged use.

[0065] In this embodiment, see Figure 2 The strap connecting piece 25 and the main unit connecting piece 15 are arranged opposite each other. By rotating the knob 21 while it is pressed, the user can move the strap connecting piece 25 toward or away from the main unit connecting piece 15, thereby adjusting the length of the strap 200.

[0066] As a further optimization of this embodiment, see Figures 2 to 4 The knob 21 is preferably located above the buckle body 1, between the strap connecting piece 25 and the main unit connecting piece 15. This angle setting allows the knob 21 to face outwards when the user wears the smartwatch, so that it is directly facing the user and can be easily operated.

[0067] Specifically, see Figures 3 to 5 The upper center of the buckle body 1 is provided with a rotating station 12 for assembling the knob 21. The rotating station 12 can be a protruding annular platform. The inner edge of the lower end face of the knob 21 is fitted onto the outer edge of the rotating station 12. The user only needs to apply a clockwise or counterclockwise force to the knob 21, and the knob 21 will rotate around the rotating station 12 under the limiting action of the rotating station 12. In this embodiment, the rotating station 12 can limit the knob 21, ensuring that the knob 21 can only move back and forth along the longitudinal direction of the rotating station 12 and rotate around the rotating station 12 under the action of the elastic element 22, which can effectively ensure that the knob 21 will not move laterally. Moreover, when the knob 21 is installed in the rotating station 12, the upper part of the knob 21 is exposed above the rotating station 12, which is used for the user's fingers to press and pinch to perform operations such as pressing down and rotating the knob 21. In a preferred embodiment, the upper surface of the knob 21 can be shaped like a frustum of a cone, and the oblique ring edge of the upper surface of the knob 21 is provided with anti-slip texture 213. The user only needs to press his / her finger against the anti-slip texture 213 and apply pressure to the anti-slip texture 213 to ensure that there is sufficient friction between the finger and the knob 21 to drive the knob 21 to rotate. Of course, in another preferred embodiment, the peripheral edge of the part of the knob 21 exposed at the rotation position 12 is provided with anti-slip texture 213. The user only needs to pinch and press the peripheral edge of the knob 21 to drive the knob 21 to rotate. The anti-slip texture 213 in the above two preferred embodiments can effectively prevent slippage during rotation, thereby greatly improving the user's operating experience.

[0068] Further, see Figure 4 and Figure 5 The rotating station 12 has a hole 13 at its center, which leads to the slide rail 11. The knob 21 has a connecting part 211 that extends through the hole 13 into the slide rail 11 to engage with the gear plate 26, thus fixing the gear plate 26 inside the slide rail 11 and enabling it to drive the rack 23. See also... Figure 4 The connecting part 211 is preferably a cylindrical structure and is located at the center of the bottom of the knob 21. A mounting hole 2111 is preferably formed at the center of the bottom of the connecting part 211. A through hole corresponding to the mounting hole 2111 is formed at the center of the gear disc 26. A screw 212 is inserted into the through hole to engage with the mounting hole 2111, thus assembling the knob 21 of the gear disc 26. Of course, the gear disc 26 and the knob 21 can also be assembled in other ways; no specific limitations are made here, and any assembly method is within the scope of protection of this patent.

[0069] Further, see Figures 3 to 5The elastic element 22 may include at least one pressing spring, which is installed inside the rotating position 12 and is used to engage with the knob 21. In a preferred embodiment, the number of pressing springs may be three, and these three pressing springs may be arranged around the periphery of the hole 13. To effectively ensure that the pressing spring does not twist or deform as the knob 21 rotates, an annular ring can be provided at the bottom of the knob 21 where it engages with the pressing spring. This ensures that the annular ring does not rotate with the knob 21 under the action of the pressing spring, effectively preventing the pressing spring from restricting the free rotation of the knob 21, thereby greatly improving the user's operating feel when rotating the knob 21.

[0070] Furthermore, a guide portion 14 can be provided inside the rotating station 12 corresponding to the position of each compression spring. The guide portion 14 can be a hollow cylindrical structure, and the pressing spring is installed inside the guide portion 14. In this way, the guide portion 14 can restrict the pressing spring from twisting in the lateral direction, ensuring that the pressing spring can only move in the longitudinal direction, thus effectively driving the knob 21 to press and rebound. Of course, in this technical solution, the number of pressing springs is not limited to three. The specific number can be flexibly set according to actual use needs, all of which are within the protection scope of this patent. For example, the number of pressing springs can be one, and it can be sleeved on the periphery of the hole 13, which can also achieve the same technical effect as described above. No further restrictions are imposed here.

[0071] In this embodiment, see Figure 3 , Figure 4 and Figure 7 The locking element 24 may include a ratchet, which may be fixedly mounted on the upper wall inside the slide rail 11 and located directly above the gear plate 26. The specific method by which the ratchet is mounted on the clasp body 1 is not specifically limited here. For example, see... Figure 6 Preferably, a limiting protrusion 17 is provided on the upper end wall of the slide 11, corresponding to the position of the hole 13, and the hole 13 passes through the limiting protrusion 17 to communicate with the slide 11. The limiting protrusion 17 is not circular; its specific structure is not specifically limited here, only that its edges have sharp corners to form a limiting feature. Correspondingly, see [reference needed]. Figure 3Preferably, a limiting groove 242 that matches the contour of the limiting protrusion 17 is provided at the middle position of the upper end face of the ratchet. When the limiting protrusion 17 is assembled in the limiting groove 242, the limiting protrusion 17 will not rotate on its own within the limiting groove 242 due to the action of its edge corners. In this way, the ratchet can be restricted from self-rotation by the snap-fit ​​cooperation between the limiting protrusion 17 and the limiting groove 242, so that it has a unique assembly posture and ensures that it is always in a fixed and stationary state. Among them, a clearance hole penetrating its wall thickness is provided at the middle position of the ratchet for the connecting part 211 of the knob 21 to pass through and mate with the gear plate 26.

[0072] Further, see Figures 7 to 9 The ratchet has a first double-ring tooth 241 on the side facing the gear disc 26, that is, the side facing away from the limiting groove 242. Correspondingly, the gear disc 26 has a second double-ring tooth 261 on the side facing the ratchet, which matches the first double-ring tooth 241. When the knob 21 is in the spring-loaded state, the first double-ring tooth 241 and the second double-ring tooth 261 engage to limit the rotation of the gear disc 26, thereby locking the rack 23. When the knob 21 is in the pressed state, the second double-ring tooth 261 moves downward to disengage from the first double-ring tooth 241. Thus, during the rotation of the knob 21, the rack 23 moves relative to the gear disc 26, causing the strap connecting piece 25 to drive the strap 200 to extend and retract.

[0073] Specifically, in this embodiment, the first double-ring tooth 241 may include a first inner ring tooth 2411 and a first outer ring tooth 2412 arranged concentrically, and the tooth patterns of the first inner ring tooth 2411 and the first outer ring tooth 2412 have opposite inclination directions. Correspondingly, the second double-ring tooth 261 may include a second inner ring tooth 2611 and a second outer ring tooth 2612 arranged concentrically, and the tooth patterns of the second inner ring tooth 2611 and the second outer ring tooth 2612 have opposite inclination directions. When the knob 21 is in the spring-loaded state, the first inner ring tooth 2411 and the second inner ring tooth 2611 engage, and the first outer ring tooth 2412 and the second outer ring tooth 2612 engage. This double-ring locking mechanism, with opposite tooth patterns on the inner and outer rings, significantly enhances the ratchet's locking effect on the gear disc 26. This prevents the gear disc 26 from rotating synchronously with the knob 21 even under significant torque, greatly improving the self-locking effect on the watch strap 200. When the knob 21 is in the pressed state, the second inner ring tooth 2611 moves downwards to disengage from the first inner ring tooth 2411. Similarly, the second outer ring tooth 2612 moves downwards to disengage from the first outer ring tooth 2412. In this way, the ratchet can release the restriction on the toothed disc 26, so that the knob 21 will drive the toothed disc 26 to rotate under the action of torque. The toothed disc 26 will then drive the rack 23 to move back and forth in the front and back directions, so as to provide the power for the strap connecting piece 25 to move forward or backward. This allows the distance between the strap connecting piece 25 and the buckle body 1 to change, thereby adjusting the length of the strap 200.

[0074] Furthermore, in this embodiment, see Figure 7 and Figure 9 The peripheral edge of the toothed disc 26 is provided with annular teeth 262. The rack 23 is mounted on the strap connecting piece 25 and is located inside the slide 11 corresponding to the side of the toothed disc 26. During the rotation of the toothed disc 26, the annular teeth 262 engage with the rack 23 to drive the rack 23 to move back and forth along the slide 11.

[0075] Specifically, see Figure 10 and Figure 11The watch strap connecting piece 25 is provided with a slider 251 on each side of the slide rail 11. The two sliders 251 are adapted to the contours of the two sides of the slide rail 11 to slide and engage with the slide rail 11 during the movement of the watch strap connecting piece 25, ensuring that the watch strap connecting piece 25 can move smoothly and will not easily slip, and greatly improving the structural strength during the adjustment process. A space is formed between the two sliders 251 to accommodate the adjustment component 2. Preferably, a receiving groove 2511 is provided on the side of one slider 251 facing the other slider 251 to install a rack 23, so that the rack 23 can be located on one side of the gear plate 26 to form a transmission engagement with the gear plate 26. Specifically, the bottom of the receiving groove 2511 may have a recessed portion 2512, and the rack 23 may have a protrusion 231 adapted to the recessed portion 2512. After the rack 23 is installed inside the receiving groove 2511, the protrusion 231 is engaged in the recess 2512, and then the rack 23 is locked inside the receiving groove 2511 by means of, for example, screws. This can greatly improve the structural strength of the rack 23, so that it can stably cooperate with the gear plate 26 in transmission.

[0076] It is worth mentioning that, in this embodiment, see Figure 7 The thickness of the rack 23 is greater than the thickness of the toothed disc 26, so that during the process of switching the knob 21 from the pressed state to the rebound state, the toothed disc 26 is always in contact with the rack 23, so that the two are always in a meshing state.

[0077] Of course, in this embodiment, see Figure 3 , Figure 4 and Figure 6 The bottom of the buckle body 1 is also detachably provided with a bottom cover 16. By removing the bottom cover 16 from the buckle body 1, the staff can quickly disassemble, repair and clean the internal parts of the buckle body 1, which greatly reduces the difficulty of maintaining the buckle component 100.

[0078] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of the present invention.
