Description

Technical Field

[0001] This invention relates to the field of watch technology, and in particular to a watch buckle and watch with a sports activity display function. Background Technology

[0002] A wristwatch, also known as a wristwatch, is an instrument worn on the wrist for timekeeping and display. Based on their power source, wristwatches are mainly divided into three types: mechanical watches, quartz watches, and smartwatches. These three types are suitable for different usage scenarios, thus meeting people's timekeeping needs in various situations. With the rise of nationwide fitness, people are paying more and more attention to their daily activity levels. This demand has led to the emergence of portable sports watches or fitness trackers with timekeeping functions. These sports watches or fitness trackers are mainly smartwatches, which record the user's steps by incorporating a pedometer or gyroscope. However, for mechanical watches, because they are powered by a mainspring within the movement, which drives gears and in turn drives the hands to achieve timekeeping, the space within the watch case is insufficient for other functional components. Furthermore, since mechanical watches do not rely on electrical power, they lack the necessary power supply for pedometers or gyroscopes. The aforementioned shortcomings make it difficult for mechanical watches to record users' activity levels. As a result, users who wear mechanical watches need to purchase other devices with activity tracking functions, increasing their purchase costs. Furthermore, wearing a watch and carrying a pedometer at the same time can be inconvenient for users when they are out and about. Summary of the Invention

[0003] Therefore, it is necessary to address the above-mentioned shortcomings by providing a buckle and watch with a step counting function. This solves the problem that traditional mechanical watches lack space inside the case to accommodate a step counting device and cannot supply power to the step counting device. By setting a step counting device on the buckle, the user's exercise level can be displayed, which meets the needs of mechanical watches for timekeeping, time display, and exercise statistics, and improves the user experience of mechanical watch users.

[0004] A watch buckle with a motion display function includes a buckle base for connecting a watch strap and a cover fastened to the buckle base for unfolding or folding the buckle base. The cover has a viewing window. A motion display mechanism, fixedly connected to the bottom of the buckle base and corresponding to the viewing window, is disposed between the cover and the buckle base. The motion display mechanism includes a housing with a digital display window on its upper surface and a step counting component housed within the housing. The step counting component includes:

[0005] Inner cover, which is fixedly connected to the inner surface of the outer shell;

[0006] A digital rotating disk is located above the inner cover and has multiple digital labels arranged in a ring to represent the user's exercise level.

[0007] An automatic hammer, wherein the automatic hammer is rotatably mounted at the bottom of the outer casing, and a spring-loaded / unloaded rotor is fixedly connected to the automatic hammer;

[0008] The mainspring is wound around the mainspring take-up and take-up rotor, with one end of the mainspring fixedly connected to the mainspring take-up and take-up rotor and the other end of the mainspring fixedly connected to the digital rotating disk. The mainspring is tightened when the automatic hammer rotates and drives the digital rotating disk to rotate, so that the digital mark at the preset position on the digital rotating disk rotates to the digital display window.

[0009] A spring wire is provided, one end of which is fixedly connected to the inner surface of the outer shell, and the other elastic end is engaged with a limiting mechanism of the digital rotary disk to constrain the rotation direction of the digital rotary disk.

[0010] A reset button extends from the bottom of the outer shell into the inner cavity and corresponds to the mating part of the spring line with the digital rotating disk. When the reset button is pressed, it pushes the spring line to release the spring line from the constraint of the digital rotating disk, thereby resetting the digital rotating disk.

[0011] In one embodiment, the housing includes a mounting cover and a bottom cover fixedly connected to the bottom of the mounting cover. The upper surface of the mounting cover is recessed to form a mounting groove. A transparent protective cover is embedded in the mounting groove, and the digital display window is opened at the bottom of the mounting groove.

[0012] In one embodiment, the lower surface of the mounting cover has a stepped groove for mounting the inner cover and the digital rotating disk. The digital display window is connected to the stepped groove. The bottom of the stepped groove has an observation window for viewing the winding status. The circumferential side of the stepped groove has a recessed hole. The circumferential side of the inner cover has a positioning position that limits the movement of the recessed hole in the circumferential direction.

[0013] In one embodiment, the lower surface of the mounting cover is provided with a countersunk hole, and the side of the mainspring winding rotor facing away from the inner cover is fitted with a positioning ball that rolls in cooperation with the countersunk hole.

[0014] In one embodiment, the upper surface of the bottom cover is provided with a limiting post, and a bearing is sleeved on the limiting post. The bearing passes through the rotation center of the automatic hammer and rotates synchronously with the automatic hammer. The bottom cover is also provided with an annular waterproof groove for embedding a waterproof ring and a stepped hole for passing through a reset button.

[0015] In one embodiment, the bearing has a plurality of shaft teeth on its annular side surface, the lower surface of the automatic hammer has a circular hole for mounting the bearing, and the inner surface of the circular hole has a limiting protrusion that engages with two adjacent shaft teeth on the bearing. The upper surface of the automatic hammer has a non-circular hole for mounting the mainspring winding rotor, and the mainspring winding rotor has a non-circular portion that is limited and engaged with the non-circular hole in the circumferential direction.

[0016] In one embodiment, the edge of the mainspring winding rotor has a limiting notch with an L-shaped cross-section. The mainspring is spirally wound around the mainspring winding rotor, and one end of the mainspring located on the inner side of the mainspring has an L-shaped connecting part that engages with the limiting notch. The digital rotating disk has a ring structure, and the digital identifier is set on the disk surface. The mainspring is housed in the digital rotating disk and fixedly connected to the digital rotating disk. One end of the mainspring located on the outer side of the mainspring has a linkage part with a U-shaped or C-shaped structure, and the inner side of the digital rotating disk has an fitting part that is adapted to the structure of the linkage part for engagement.

[0017] In one embodiment, the outer ring surface of the digital rotary disk is provided with a plurality of limiting teeth distributed in a ring, and the free end of the spring line is provided with a V-shaped hook for successively engaging each of the limiting teeth.

[0018] In one embodiment, the reset button includes a screw for passing through the stepped hole, a waterproof ring sleeved on the screw, and a positioning member fixed to the end of the screw. The positioning member passes through the inner cover and can extend and retract relative to the inner cover. The end of the positioning member is provided with a push pin connected by an elastic member, and the positioning member is provided with a guide slope on the side of the elastic member.

[0019] The present invention also discloses a watch that includes the aforementioned buckle with an exercise display function.

[0020] The buckle and watch with exercise display function of the present invention have an exercise display mechanism set between the buckle base and the faceplate. When the user exercises while wearing the watch, the automatic hammer of the exercise counting component rotates under the action of the user's arm swing, and drives the mainspring winding rotor to rotate synchronously. This causes the mainspring winding rotor to continuously tighten the mainspring, which in turn drives the digital disc to rotate, aligning the corresponding number on the digital disc with the digital display window on the case. The user can then judge their current exercise level by the number displayed in the digital display window, thereby understanding their current exercise volume. While satisfying the user's exercise volume statistics, it does not occupy the space inside the watch head, does not require electric power, is more energy-efficient and environmentally friendly, and users only need to purchase one watch to meet multiple needs, reducing user purchase costs and improving the user experience.

[0037] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] This invention addresses the problems of insufficient internal space in traditional mechanical watches, making it difficult to accommodate motion tracking devices and lacking the functionality for electronic motion tracking devices. It provides a method to display the user's exercise level by incorporating a step counter on the clasp. Since the step counter is located on the clasp, it does not occupy space within the watch head, reducing the design complexity of the internal space. The automatic hammer rotates under the user's arm movements, thereby driving the rotation of other components. The exercise level is displayed through mechanical transmission, eliminating the need for a power supply device and reducing the watch's design cost.

[0039] For specific details, please refer to... Figure 1-4 The watch buckle with exercise display function in this embodiment includes a watch buckle base 100 for connecting the watch strap and a cover 200 that is fastened to the watch buckle base 100 and used to unfold or fold the watch buckle base 100. A viewing window 210 is provided on the cover 200. An exercise display mechanism is provided between the cover 200 and the watch buckle base 100 and is fixedly connected to the bottom of the watch buckle base 100 and corresponds to the viewing window 210. In this way, the user can clearly see the exercise level value displayed by the exercise display mechanism through the viewing window 210. The clasp base 100 includes a connecting base 110 hinged to the watch band on one side of the watch head, and a folding member 120 hinged to the connecting base 110. The connecting base 110 has a receiving groove or receiving hole 111 for accommodating the folded member 120. One end of the folding member 120 away from the connecting base 110 is connected to one end of the faceplate 200. The other end of the faceplate 200 is hinged to the watch band on the other side of the watch head, and the bottom of the faceplate 200 away from the folding member 120 is detachably engaged with the connecting base 110. In this embodiment, the connecting base 110 and the faceplate 200 are respectively connected to the beads on the watch band via tail beads, and the connecting base 110 and the faceplate 200 are respectively hinged to the corresponding tail beads via spring bars or connecting screws. Preferably, the connecting base 110 is connected to a 6H tail bead 112, and the faceplate 200 is connected to a 12H tail bead 220.

[0040] The motion display mechanism includes a housing 300 with a digital display window 310 on its upper surface and a motion counting component 400 housed within the housing 300. The housing 300 is used to house the motion counting component 400 so that the motion display mechanism can be assembled as a whole on the face cover 200, thereby improving the stability of the motion display mechanism. The pedometer component 400 includes an inner cover 410, a digital rotating disk 420, an automatic hammer 430, a spring 440, a spring wire 450, and a reset button 460. The inner cover 410 is fixedly connected to the inner surface of the outer casing 300. The digital rotating disk 420 is located above the inner cover 410 and has multiple circularly distributed digital indicators 421 corresponding to the user's exercise level. The automatic hammer 430 is rotatably mounted at the bottom of the outer casing 300, and a spring winding rotor 470 is fixedly connected to the automatic hammer 430. The spring 440 is wound around the spring winding rotor 470, with one end of the spring 440 fixedly connected to the spring winding rotor 470 and the other end of the spring 440 connected to the digital rotating disk 420. A fixed connection is established. The spring 440 tightens when the automatic hammer 430 rotates, driving the digital rotating disk 420 to rotate, so that the preset position of the digital indicator 421 on the digital rotating disk 420 rotates to the digital display window 310. One end of the spring wire 450 is fixedly connected to the inner surface of the housing 300, and the other end is elastically engaged with the digital rotating disk 420 to constrain the rotation direction of the digital rotating disk 420. The reset button 460 extends from the bottom of the housing 300 into the inner cavity of the housing 300 and corresponds to the engagement part of the spring wire 450 with the digital rotating disk 420. When the reset button 460 is pressed, it pushes the spring wire 450 to release the constraint of the spring wire 450 on the digital rotating disk 420, so that the digital rotating disk 420 resets.

[0041] In this embodiment, after the user wears the watch equipped with the aforementioned buckle, when the user moves, the automatic hammer 430 inside the inner casing 410 will rotate as the user's arm swings. The rotation of the automatic hammer 430 drives the mainspring winding rotor 470 to rotate, thereby pulling the mainspring 440 to tighten, causing the digital display disc 420 to rotate synchronously. Thus, as the user's exercise intensity increases, the mainspring 440 tightens more rapidly, and the value in the corresponding digital display window 310 on the digital display disc 420 changes. By observing the value displayed in the digital display window 310, the user can determine the current level of exercise, thus providing a reference for the user's exercise status.

[0042] The faceplate 200 serves two purposes: firstly, it secures the clasp base 100 when folded, allowing for adjustment of the length of the strap connection points on both sides of the watch head, facilitating the fixation of the watch head to the user's wrist; secondly, it also houses the motion display mechanism and provides a window for displaying the results. In this embodiment, the housing 300 of the motion display mechanism is mounted on the faceplate 200 with screws. Specifically, the upper surface of the faceplate 200 has multiple countersunk holes 230 for inserting screws, and the viewing window 210 is located in the center of the upper surface of the faceplate 200 and has an irregular shape. The front end of the faceplate 200 has two protruding lugs that are hinged to the folding member 120, each lug having a through hole for mounting a button. The rear end of the faceplate 200 has a retainer for mounting the 12H tail bead, and the front and rear ends of the faceplate 200 form an arched structure to ensure a close fit with the clasp base 100 when fastened.

[0043] Please combine Figure 3 and Figure 5 The outer casing 300 includes a mounting cover 320 and a bottom cover 330 fixedly connected to the bottom of the mounting cover 320. The upper surface of the mounting cover 320 is recessed to form a mounting groove 321. A transparent protective cover 340 is embedded in the mounting groove 321, and a digital display window 310 is provided at the bottom of the mounting groove 321. In this embodiment, the mounting cover 320 is fixed to the bottom of the face cover 200 by screws, and the upper surface of the mounting cover 320 is in contact with the lower surface of the face cover 200. The transparent protective cover 340 can be made of glass or transparent resin material. Depending on the design requirements, the mounting groove 321 can be designed as an irregular structure, or as a regular circular or polygonal structure, etc. A waterproof rubber ring 350 is provided on the edge of the transparent protective cover 340 to prevent water stains from entering the inner cavity of the outer casing 300 through the gap between the transparent protective cover 340 and the mounting groove 321, thereby causing corrosion of the metal parts inside the outer casing 300 and contamination of the parts caused by impurities entering the outer casing 300, which would affect the clear display of the digital mark 421.

[0044] Please combine Figure 3 , Figure 5 and Figure 6The lower surface of the mounting cover 320 has a stepped groove 360 ​​for mounting the inner cover 410 and the digital rotating disk 420. The stepped groove 360 ​​is used to limit the inner cover 410 to prevent the motion counting component 400 from shaking during user movement. The digital display window 310 communicates with the stepped groove 360. The bottom of the stepped groove 360 ​​has an observation window 370 for viewing the state of the spring 440. There can be one or more observation windows 370. When the number of observation windows 370 is greater than one, the multiple observation windows 370 are arranged in a ring around the center of the bottom of the stepped groove 360. Furthermore, the stepped groove 360 ​​has a recessed hole 380 on its annular side, and the inner cover 410 has a positioning position 411 that is matched with the recessed hole 380 in the circumferential direction to fix the inner cover 410 and prevent the inner cover 410 from rotating relative to the mounting cover 320, thereby causing the problem that the motion level displayed by the digital rotating disk 420 does not match the actual motion.

[0045] In a further preferred embodiment, the lower surface of the mounting cover 320 is provided with a countersunk hole 390, and the side of the spring winding rotor 470 facing away from the inner cover 410 is fitted with a positioning ball 480 that rolls with the countersunk hole 390. The positioning ball 480 is a positioning steel ball. The upper surface of the spring winding rotor 470 is provided with a groove or hole 471 for rolling and fitting the positioning ball 480. In this way, the positioning ball 480 separates the pedometer component 400 from the lower surface of the mounting cover 320, thereby achieving clearance for the pedometer component 400 and avoiding friction caused by the upper surface (disc surface) of the digital rotating disk 420 abutting against the lower surface of the mounting cover 320, thus ensuring the smooth rotation of the digital rotating disk 420.

[0046] Please combine Figure 3 and Figure 7 The lower part of the inner cover 410 is used to rotatably mount the automatic hammer 430, and the upper part of the inner cover 410 is used to support the mainspring 440 and the digital rotating disk 420. In this embodiment, the inner cover 410 serves two purposes: firstly, it supports the automatic hammer 430, the mainspring 440, and the digital rotating disk 420; secondly, it separates the automatic hammer 430 from the mainspring 440 and the digital rotating disk 420, ensuring that the components above the inner cover 410 do not interfere with the operation of the automatic hammer 430, thus ensuring its reliable operation. In this embodiment, the upper surface of the inner cover 410 has an opening to allow the mainspring winding and unwinding rotor 470 to pass through, thereby enabling the automatic hammer 430 to transmit power to the components above the inner cover 410.

[0047] Please combine Figure 3 and Figure 8The digital rotating disk 420 has a ring-shaped structure, and digital markers 421 are set on the surface of the digital rotating disk 420. In this embodiment, there are 12 digital markers 421, numbered 00-11, arranged clockwise on the surface of the digital rotating disk 420. These 12 digital markers 421 are divided into three consecutive groups, representing three levels of exercise intensity. Among them, digital markers 421 numbered 00-03 are red, indicating that the user's current exercise intensity is very low; digital markers 421 numbered 04-08 are green, indicating that the user's current exercise intensity is good; and digital markers 421 numbered 09-11 are yellow, indicating that the user's current exercise intensity is high. When the digital disc 420 rotates under the drive of the spring 440, as the user's exercise intensity increases, the total number of rotations of the automatic hammer 430 increases, and the spring 440 tightens more, causing each digital indicator 421 to pass through the digital display window 310 sequentially in a clockwise direction (from smallest to largest value). This allows the user to determine the current level of exercise based on the values ​​displayed in the digital display window 310. In other embodiments, depending on the elasticity of the spring 440, the number of digital indicators 421 on the digital disc 420 can be increased or decreased, which will not be elaborated here.

[0048] Furthermore, in one embodiment, the outer ring surface of the digital rotating disk 420 is provided with a plurality of ring-shaped limiting teeth 422, and the free end of the elastic wire 450 is provided with a V-shaped hook portion 451 for successively engaging each limiting tooth 422. In this embodiment, the elastic wire 450 is obtained by bending an elastic metal wire, and the elastic wire 450 has an overall C-shaped structure. One end of the elastic wire 450 is bent into a U-shaped structure and inserted into a hole in the inner wall of the mounting cover 320 to achieve limiting. The V-shaped hook portion 451 at the other end of the elastic wire 450 is hooked or engaged in the groove between two adjacent limiting teeth 422 on the outer ring surface of the digital rotating disk 420. During the operation of the pedometer component 400, as the digital rotating disk 420 rotates, the V-shaped hook part 451 of the spring wire 450 engages with each groove on the outer ring surface of the digital rotating disk 420 in turn. That is, the V-shaped hook part 451 bounces along the limiting teeth 422 one by one as the digital rotating disk 420 rotates, thereby constraining the digital rotating disk 420. This avoids the problem that the number displayed in the digital display window 310 does not match the actual amount of exercise caused by the automatic rotation of the digital rotating disk 420, and improves the reliability of the step counting result of the pedometer component 400.

[0049] Please refer to further information. Figure 3 , Figure 8 as well as Figure 13The mainspring 440 is spirally wound around the mainspring winding rotor 470 and is housed within and fixedly connected to the digital rotating disk 420. One end of the mainspring 440 located on the outer side is provided with a linkage part 441 in the form of a U-shape or C-shape. The inner side of the digital rotating disk 420 is provided with a fitting part 423 that is adapted to the structure of the linkage part 441 for engagement. It can also be understood that the mainspring winding rotor 470, the mainspring 440 and the digital rotating disk 420 are arranged concentrically from the inside out, all three are located in the same plane and are fixedly connected in sequence so as to transmit the rotation of the automatic hammer 430 to the digital rotating disk 420.

[0050] The automatic hammer 430 rotates synchronously with the swing of the user's arm to power the rotation of the digital dial 420, thus automatically rotating according to changes in the amount of movement to control the numbers displayed on the digital dial 420. For details, please refer to... Figure 3 , Figure 9 as well as Figure 10 The automatic hammer 430 has an eccentric rotating structure. It includes an arc-shaped counterweight 431 and a rotating ring 433 located at the rotation center inside the arc-shaped counterweight 431 and fixed to it via multiple connecting ribs 432. The arc-shaped counterweight 431 has concave arc surfaces at both ends to reduce resistance during rotation. Weight-reducing holes are formed between adjacent connecting ribs 432 to reduce the weight of the automatic hammer 430, thereby reducing the impact of the motion display mechanism on the overall weight of the clasp and lessening the burden on the user. In this embodiment, the automatic hammer 430 is designed with an eccentric rotating structure. When the user's arm swings, the stability of the automatic hammer 430 is disrupted, and it rotates under the eccentric action of the arc-shaped counterweight 431 to provide power for the rotation of the digital rotating disk 420. The upper surface of the automatic hammer 430 is provided with a non-circular hole 434 for mounting the mainspring winding rotor 470. The mainspring winding rotor 470 is provided with a non-circular portion 472 that is circumferentially limited and matched with the non-circular hole 434. Specifically, the non-circular hole 434 is located on the upper part of the rotating ring 433 and is used to realize the circumferential matching between the automatic hammer 430 and the mainspring winding rotor 470 to ensure the synchronous rotation of the automatic hammer 430 and the mainspring winding rotor 470.

[0051] To ensure smooth rotation of the automatic hammer 430, please combine... Figure 3 , Figure 9 , Figure 15 as well as Figure 16The upper surface of the bottom cover 330 is provided with a limiting post 331, and a bearing 490 is sleeved on the limiting post 331. The bearing 490 passes through the rotation center of the automatic hammer 430 and rotates synchronously with the automatic hammer 430. The bearing 490 includes an outer ring 491, an upper pile ring, a lower pile ring, a retaining ring, and a ball assembly. The middle part of the bearing 490 is sleeved on the limiting post 331. Furthermore, the ring side of the bearing 490 is provided with several shaft teeth 492. The lower surface of the automatic hammer 430 is provided with a circular hole 435 for embedding the bearing 490, and the inner surface of the circular hole 435 is provided with a limiting protrusion 436 that engages with two adjacent shaft teeth 492 on the bearing 490. In this way, the circumferential limitation of the bearing 490 and the automatic hammer 430 can be achieved by the engagement of the limiting protrusion 436 with the shaft teeth 492, so that the automatic hammer 430 can drive the bearing 490 to rotate quickly when it rotates. In addition, in this embodiment, the bottom cover 330 is also provided with an annular waterproof groove 332 for mounting a waterproof ring, a stepped hole 333 for passing through the reset button 460, and a screw hole 334 for passing through a screw to connect the bottom cover 330 and the mounting cover 320. Furthermore, the bottom surface of the bottom cover 330 is provided with a through groove to reduce the thickness and weight of the bottom cover 330, thereby ultimately reducing the overall thickness and weight of the motion display mechanism, avoiding the influence of the motion display mechanism on the thickness of the buckle, and reducing the burden on the user when wearing the watch.

[0052] The mainspring winding and unwinding rotor 470 serves as the transmission mechanism between the automatic hammer 430 and the mainspring 440, and also as a limiting mechanism for the mainspring 440. For details, please refer to... Figure 3 , Figure 11 as well as Figure 12 The edge of the mainspring winding rotor 470 is provided with a limiting notch 473 with an L-shaped cross-section, and the end of the mainspring 440 located on the inner side of the mainspring 440 is provided with an L-shaped connecting part 442 that engages with the limiting notch 473, so as to achieve a fixed connection between the mainspring 440 and the mainspring winding rotor 470.

[0053] Please combine Figure 3 , Figure 14 as well as Figure 15The reset button 460 includes a screw 461 for passing through the stepped hole 333, a waterproof ring 462 sleeved on the screw 461, and a positioning member 463 fixed to the end of the screw 461. The positioning member 463 passes through the inner cover 410 and can extend and retract relative to the inner cover 410. The end of the positioning member 463 is provided with a push pin 465 connected by an elastic member 464, and a guide slope 466 is provided on the side of the positioning member 463 relative to the elastic member 464. The guide slope 466 is used to reduce the resistance when the positioning member 463 extends. The elastic member 464 is a spring. Furthermore, the edge of the inner cover 410 is provided with a notch 412 that conforms to the outer contour of the positioning member 463 to constrain the rotation of the positioning member 463. When the user needs to reset the digital disc 420, simply press the head of the screw 461 below the bottom cover 330. The positioning member 463 moves upward, causing the push pin 465 to push the end of the spring wire 450, disengaging the V-shaped engagement part 451 from the limiting teeth 422 on the outer ring surface of the digital disc 420. In this case, the constraint of the spring wire 450 on the digital disc 420 is released. Similarly, the traction force from the digital disc 420 on the spring 440 is released, and the spring 440 drives the digital disc 420 to rotate in the opposite direction to reset, allowing the user to restart step counting. After the digital disc 420 is reset, release the screw 461 of the reset button 460. The squeezing force from the screw 461 on the elastic member 464 is released, and the elastic member 464 resets and drives the push pin 465 to retract. At the same time, the V-shaped engagement part 451 of the spring wire 450 re-engages with the limiting teeth 422 on the ring side of the digital disc 420, allowing a new round of step counting to begin. In this embodiment, when the push pin 465 extends, the push pin 465 is located outside the limiting tooth 422 to avoid the push pin 465 interfering with the reset of the limiting tooth 422. The push pin 465 releases the constraint of the spring wire 450 on the digital rotary disk 420 by pushing the part of the V-shaped hook 451 of the spring wire 450 that extends out of the limiting tooth 422.

[0054] In addition, the present invention also discloses a watch, which includes the aforementioned buckle with a sports activity display function, and further includes a first strap connected to the buckle base 100, a second strap connected to the faceplate 200, and a watch head disposed between the first and second straps. It should be noted that the watch in this embodiment can be not only a mechanical watch powered by the movement through the rotation of the hands, but also a quartz watch or a smart watch using the same buckle base 100 and faceplate 200 connection method.

[0055] The buckle and watch with exercise display function of the present invention are provided with an exercise display mechanism between the buckle base 100 and the face cover 200. When the user exercises after wearing the watch, the automatic hammer 430 of the exercise counting component 400 rotates under the action of the user's arm swing and drives the mainspring winding rotor 470 to rotate synchronously. The mainspring winding rotor 470 pulls the mainspring 440 to continuously tighten. The mainspring 440 further drives the digital rotating disk 420 to rotate, so that the corresponding digital mark 421 on the digital rotating disk 420 is aligned with the digital display window 310 on the outer casing 300. The user can judge his / her current exercise level by the number displayed in the digital display window 310, thereby understanding the current exercise volume. While satisfying the user's exercise volume statistics, it does not occupy the space inside the watch head, does not need to use electric power, is more energy-saving and environmentally friendly, and users only need to purchase one watch to meet multiple needs, reducing the user's purchase cost and improving the user experience.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
