Watch straps, watch strap link assemblies, and wearable devices

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on January 12, 2024, with application number 202410051894.0 and invention name “Watch strap, watch strap link assembly, wearable device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of wearable devices, and in particular to a wearable device, a watch strap that can be used in the wearable device, and a watch strap link assembly that can be used in the watch strap. Background Art

[0003] Wearable devices generally refer to miniature electronic devices that can be worn on the body for activities, and primarily include smart watches and smart bracelets. Smart watches and smart bracelets can be used independently or as portable accessories for mobile devices.

[0004] Wearable devices mainly include a dial and a strap. The strap includes multiple links connected in sequence. The links between two adjacent links are mostly fixed or difficult to disassemble quickly, which brings inconvenience to the adjustment of the strap length.

[0005] Summary of the Invention

[0006] The present application provides a wearable device, a watch strap that can be used in the wearable device, and a watch strap link assembly that can be used in the watch strap. The purpose is to provide a structure that can quickly disassemble the watch strap links.

[0007] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0008] In a first aspect, the present application provides a watch strap that can be applied to a wearable device, for example, the wearable device can be a watch or a bracelet.

[0009] The watch strap provided in the present application includes a plurality of links connected in sequence, the plurality of links including a first link and a second link, the first link and the second link are detachably connected and can be switched between a locked state and an unlocked state; the first link includes a locking rod, the extension direction of the locking rod is parallel to the width direction of the first link, the second link includes a locking buckle, and a clamping space and a first opening connected to the clamping space are provided in the locking buckle.

[0010] When the lock buckle is connected to the locking rod, the locking rod passes through the first opening and is located in the clamping space, connecting the first chain link and the second chain link, so that the first chain link and the second chain link are in a locked state.

[0011] When the lock buckle moves along the thickness direction of the second link, the lock rod can be removed from the clamping space and the first opening, and the first link and the second link can be separated, so that the first link and the second link are in an unlocked state.

[0012] When the length of the watch strap needs to be shortened and some links need to be removed, for example, when removing the connected first link and second link, the lock buckle can be pressed along the thickness direction of the link and the second link can be moved away from the first link. The locking rod of the first link can then be withdrawn from the engaging space of the second link and the first opening to achieve unlocking, so that the first link and the second link are in a separated state.

[0013] Alternatively, when the first link and the second link need to be connected, the end of the second link with the lock buckle and the end of the first link with the locking rod are close to each other, and the locking rod can be inserted into the clamping space through the first opening to achieve the locking of the first link and the second link.

[0014] In the watch strap of the example of this application, not only is the disassembly and assembly structure simple, but the operation is also easy when disassembling and assembling the links. The links can be disassembled and assembled quickly, thereby improving the user experience.

[0015] In one possible implementation, the second link further comprises a chamber and a second opening communicating with the chamber, the second opening communicating with the first opening, and the lock is disposed in the chamber. For example, the lock is slidably disposed in the chamber and slides along the thickness direction of the link.

[0016] In one feasible manner, the locking rod of the first link can sequentially pass through the second opening of the second link, and the first opening is located in the locking space, and the locking rod is connected to the locking buckle, so that the first link and the second link are in a locked state; the locking buckle moves along the thickness direction of the link, and the locking rod withdraws from the locking space, the first opening and the second opening in sequence, and the locking rod and the locking buckle are separated, so that the first link and the second link are in an unlocked state.

[0017] In this example, a chamber is opened in the chain link, and the lock buckle is slidably arranged in the chamber. In order to allow the locking rod to withdraw from the chamber, a second opening connected to the chamber is also opened on the chain link, so that the locking rod can pass through the second opening and the first opening and be inserted into the locking space.

[0018] In one possible implementation, an elastic member is provided in the chamber, connecting the lock buckle and the second link; when the first link and the second link are connected, the elastic member is used to apply elastic force to the lock buckle along the thickness direction of the second link.

[0019] By utilizing the elastic force of the elastic member on the lock buckle, when the first link and the second link are in the locked state, the lifting lock rod can be continuously and stably locked in the clamping space, thereby improving the locking reliability.

[0020] In one possible implementation, the lock buckle has a receiving groove, the depth of which is parallel to the thickness of the second link. The elastic member is at least partially disposed within the receiving groove, with one end of the elastic member abutting the second link and the other end abutting the lock buckle. Upon the removal of an external force applied to the lock buckle along the thickness of the link and into the link, the elastic force of the elastic member causes the first and second links to switch to a locked state.

[0021] By opening a seating groove on the lock buckle with a depth direction parallel to the thickness direction of the chain link and arranging the elastic member in the seating groove, not only can the thickness dimension of the entire chain link be compressed, but the seating groove can also play a limiting role, so that the elastic force of the elastic member on the lock buckle is basically parallel to the thickness direction of the chain link.

[0022] In one feasible manner, the wall surfaces of the lock buckle used to enclose the locking space include: a first wall surface and a second wall surface facing the first wall surface; when the first link and the second link are connected, the locking rod abuts against the second wall surface; when the lock buckle moves along a first direction, the locking rod moves along a second direction opposite to the first direction, and the first direction points from the first wall surface to the second wall surface.

[0023] When the first link and the second link are in a locked state, the locking rod abuts against the wall surface, which can improve the stability and reliability of the locking of the two links.

[0024] In one possible implementation, the wall of the lock used to enclose the first opening includes an opening wall, for example, the opening wall is connected to the second wall, and the opening wall is an inclined surface; the inclined surface includes a first end and a second end, and the first end is closer to the second wall than the second end; the distance from the first end to the first wall is smaller than the distance from the second end to the first wall.

[0025] Since one wall of the opening is set as an inclined surface, the locking rod can easily slide into the locking space of the lock along the inclined surface, or the locking rod located in the locking space can also easily slide out along the inclined surface, thereby improving the user experience of locking and unlocking.

[0026] In one practicable manner, the second link further includes a limiting structure, and the limiting structure is used to limit the distance that the lock buckle moves along the thickness direction of the second link.

[0027] In one achievable method, the limiting structure includes: a limiting groove and a limiting column slidably arranged in the limiting groove, and the extension direction of the limiting groove is parallel to the thickness direction of the second link; one of the limiting groove and the limiting column is arranged on the second link, and the other is arranged on the lock buckle.

[0028] By using a simple limit groove and limit column, the movement distance of the lock buckle along the thickness direction of the chain link can be limited, so that the locking rod can slide into the locking space of the lock buckle more accurately to achieve the locking connection of the two chain links.

[0029] In one implementation, along the width direction of the first link, the first link has a first side and a second side, the locking rod extends from the first side to the second side; and the first opening extends from the first side to the second side.

[0030] In this implementation structure, a locking rod is included, and the locking rod can slide into the locking space of the lock buckle through the first opening.

[0031] In one possible implementation, along the width direction of the first link, the first link has a first side and a second side; the locking rod includes a first locking rod and a second locking rod, one end of the first locking rod is connected to the first side, and the other end extends toward the second side, one end of the second locking rod is connected to the second side, and the other end extends toward the first side; the snap-fitting space in the lock buckle includes: a first snap-fitting space toward the first side, and a second snap-fitting space toward the second side, the first snap-fitting space is used to accommodate the first locking rod, and the second snap-fitting space is used to accommodate the second locking rod.

[0032] In this embodiment, two locking rods are included. The two locking rods can be symmetrically arranged, and two corresponding locking spaces are provided.

[0033] In one achievable manner, the first link includes a concave cavity in which the locking rod is disposed, and the second link includes a protrusion in which the locking catch is disposed; when the first link and the second link are connected, the protrusion is located in the concave cavity.

[0034] In one practicable manner, a first mounting hole is provided on a wall surface of the first link for enclosing the concave cavity, a second mounting hole is provided on the lock buckle, and the latch passes through the first mounting hole and extends into the second mounting hole.

[0035] In one possible implementation, a radial dimension of a portion of the latch that extends into the second mounting hole is smaller than a diameter of the second mounting hole.

[0036] In this example, the pin can not only realize the detachable connection between the lock buckle and the chain link, making it easy to disassemble and assemble the lock buckle; in addition, the sliding fit between the pin and the second mounting hole can limit the moving distance of the lock buckle along the thickness direction of the chain link, thereby improving the fit accuracy between the locking rod and the lock buckle.

[0037] In one possible implementation, along the thickness direction of the second link, the second link has a first surface and a second surface back to back, the first surface is closer to the skin than the second surface, a through hole is provided on the first surface, and at least part of the lock buckle extends through the through hole into the second link.

[0038] In some examples, the surface of the buckle intended to be brought into contact with the skin is flush with the first surface of the first link.

[0039] In a second aspect, the present application provides a wearable device, which includes a dial and a strap in any of the above-mentioned implementations, wherein the strap is connected to the dial.

[0040] Since the wearable device includes a watchband in any of the above-mentioned implementations, the lock buckle and the locking rod cooperate to enable quick assembly and disassembly of adjacent links in the watchband. For example, when a link needs to be disassembled, the lock buckle can be pressed, and the locking rod can be withdrawn from the locking space of the lock buckle, thereby unlocking the two adjacent links. For another example, when the links need to be connected, the two links can be brought closer together, and the locking rod can be slid into the locking space of the lock buckle, thereby locking the two links. The quick-detachable link has a simple structure and is easy to assemble and disassemble.

[0041] On the third aspect, the present application provides a watch strap link assembly, which includes a link, a locking rod is provided at one end of the link, and a locking buckle is provided at the other end, the extension direction of the locking rod is parallel to the width direction of the link, and a clamping space and a first opening connected to the clamping space are provided in the locking buckle.

[0042] When a link is connected to another link, the locking rod of the link passes through the first opening of the other link and is located in the clamping space, connecting the lock buckle and the locking rod, so that the link and the other link are in a locked state; when the lock buckle of the other link moves along the thickness direction of the link, the locking rod can be removed from the clamping space and the first opening, and the link and the other link are separated, so that the link and the other link are in an unlocked state.

[0043] The watch strap link assembly is applied to the watch strap to realize the quick disassembly and assembly of two adjacent links. In addition, the structure for realizing quick disassembly and assembly is relatively simple. For example, pressing the lock buckle can unlock the two links. The two links are close to each other, and the locking rod is inserted into the clamping space of the lock buckle to lock the two links together. The operation is simple and can improve the user experience.

[0044] In one practicable manner, the chain link further comprises a chamber and a second opening communicating with the chamber, the second opening is communicated with the first opening, and the lock buckle is disposed in the chamber.

[0045] The locking rod of the chain link can pass through the second opening and the first opening of the other chain link in sequence and be located in the clamping space, so that the chain link and the other chain link are in a locked state; the lock buckle moves along the thickness direction of the chain link, and the locking rod withdraws from the clamping space, the first opening and the second opening, so that the chain link and the other chain link are in an unlocked state.

[0046] A chamber is provided in the link, and the lock buckle is slidably arranged in the chamber. A second opening communicating with the chamber is also provided on the link, so that the lock rod can pass through the second opening and the first opening and be inserted into the clamping space.

[0047] In one possible implementation, an elastic member is provided in the chamber, and the elastic member connects the lock buckle and the chain link; when the chain link is connected to another chain link, the elastic member is used to give the lock buckle an elastic force along the thickness direction of the chain link.

[0048] By utilizing the elastic force of the elastic member on the lock buckle, the connection stability between the lock rod and the lock buckle can be improved when in the locked state.

[0049] In one practicable manner, the lock buckle is made of an elastic material, for example, a memory alloy material.

[0050] In one practicable manner, the watch strap link assembly further includes a limiting structure, which is used to limit the distance that the lock buckle moves along the thickness direction of the link.

[0051] In this way, the locking rod can be slid into the engaging space of the lock buckle more accurately.

[0052] In one achievable method, the limiting structure includes: a limiting groove and a limiting column slidably arranged in the limiting groove, and the extension direction of the limiting groove is parallel to the thickness direction of the chain link; one of the limiting groove and the limiting column is arranged on the chain link, and the other is arranged on the lock buckle.

[0053] In one feasible manner, the wall surfaces of the lock buckle used to enclose the locking space include: a first wall surface and a second wall surface facing the first wall surface; when a chain link is connected to another chain link, the locking rod abuts against the second wall surface; when the lock buckle moves along a first direction, the locking rod moves along a second direction opposite to the first direction, and the first direction points from the first wall surface to the second wall surface.

[0054] When the two chain links are in a locked state, the locking rod rests against a wall surface of the clamping space, which can improve stability and reliability.

[0055] In one achievable method, the wall surface of the lock used to enclose the first opening includes an opening wall surface, and the opening wall surface is an inclined surface; the opening wall surface includes a first end and a second end, and the first end is closer to the second wall surface than the second end; the distance from the first end to the first wall surface is smaller than the distance from the second end to the first wall surface.

[0056] The locking rod can slide into the engaging space of the lock buckle relatively easily along the inclined surface, or the locking rod located in the engaging space can also slide out relatively easily along the inclined surface, thereby improving the user experience of locking and unlocking.

[0057] In one implementation, along the width direction of the link, the link has a first side and a second side, the locking rod extends from the first side to the second side; and the first opening extends from the first side to the second side.

[0058] This implementation structure includes a locking rod, and the corresponding first opening is also an opening that passes through the first side and the second side.

[0059] In one feasible manner, the link has a first side and a second side along the width direction of the link; the locking rod includes a first locking rod and a second locking rod, one end of the first locking rod is connected to the first side, and the other end extends toward the second side, one end of the second locking rod is connected to the second side, and the other end extends toward the first side; the snap-fitting space in the lock buckle includes: a first snap-fitting space facing the first side, and a second snap-fitting space facing the second side, the first snap-fitting space is used to accommodate the first locking rod, and the second snap-fitting space is used to accommodate the second locking rod.

[0060] This implementation structure includes two locking rods.

[0061] In one possible implementation, one end of the link includes a cavity and the other end includes a protrusion, the locking rod is arranged in the cavity, and the locking buckle is arranged in the protrusion; when the link is connected to another link, the protrusion is located in the cavity.

[0062] In one possible implementation, a first mounting hole is provided on a wall surface of the chain link for enclosing the concave cavity, a second mounting hole is provided on the lock buckle, and the latch passes through the first mounting hole and extends into the second mounting hole.

[0063] In one possible implementation, a radial dimension of a portion of the latch that extends into the second mounting hole is smaller than a diameter of the second mounting hole.

[0064] In this example, the pin can not only realize the detachable connection between the lock buckle and the chain link, making it easy to disassemble and assemble the lock buckle; in addition, the sliding fit between the pin and the second mounting hole can limit the moving distance of the lock buckle along the thickness direction of the chain link, thereby improving the fit accuracy between the locking rod and the lock buckle.

[0094] The present invention provides a wearable device, such as a smart bracelet or smart watch, which can be worn on the wrist and can display time, record time, report time, provide message notifications, detect exercise, monitor heart rate, and detect blood oxygen levels.

[0095] The wearable device may include a watch strap and a watch dial. The watch strap is used to wrap around the user's wrist to enable the wearable device to be worn, and the watch dial is used for display.

[0096] As shown in Figures 1 and 2, Figures 1 and 2 illustrate exemplary structural diagrams of a watchband for a wearable device. The exemplary watchband 100 includes a plurality of sequentially connected links 101. The exemplary watchband 100 may be a metal or ceramic watchband.

[0097] To make the strap length adjustable, some adjacent links 101 may be detachably connected. This allows users to remove some links 101 to shorten the strap, or add some links 101 to extend the strap, to precisely fit the wrist and enhance user experience.

[0098] In order to quickly and conveniently disassemble and assemble chain links, the present application exemplarily provides a chain link quick-disassembly structure, and the structure that can be implemented by the chain link quick-disassembly structure is shown below.

[0099] As shown in Figures 3 and 4, Figure 3 is a structural diagram of one of the links in a watch strap according to an example of the present application, and Figure 4 is an exploded view of Figure 3.

[0100] 3 and 4 , a locking rod 1 is provided at one end of the chain link 101 , and a locking buckle 2 is provided at the other end. A locking space 3 and a first opening 6 communicating with the locking space 3 are provided in the locking buckle 2 .

[0101] In the example of this application, the locking rod 1 extends parallel to the width of the link 101 (e.g., direction S in FIG4 ). The locking buckle 2 can move along the thickness of the link 101 (e.g., direction H in FIG4 ). It is understood that the width of the link 101 can be the width of the watchband 100.

[0102] In some examples, a cavity 5 may be provided at the end of the link 101 where the buckle 2 is provided, and the buckle 2 is slidably provided in the cavity 5. The link 101 may also be provided with a second opening 7 communicating with the cavity 5.

[0103] In the embodiment of the present application, one end of the link 101 where the locking rod 1 is provided may be close to the end of another link, and the other end of the link 101 where the locking buckle 2 is provided may be close to the end of yet another link.

[0104] In the example of the watch strap of the present application, some adjacent links can be connected and separated, so as to switch between a locked state and an unlocked state. In the example of the present application, two adjacent links are connected to form a locked state, and two adjacent links are separated to form an unlocked state.

[0105] As shown in Figures 5, 6, and 7, Figures 5 to 7 respectively illustrate the corresponding structural diagrams of two adjacent chain links in the locked and unlocked states. Figure 5 shows the structural diagram of the first chain link 101A and the second chain link 101B in the locked state, Figure 6 shows the structural diagram of the first chain link 101A and the second chain link 101B when the lock buckle 2 is pressed, and Figure 7 shows the structural diagram of the first chain link 101A and the second chain link 101B in the unlocked state.

[0106] As shown in FIG5 , the locking rod 1 of the first link 101A is located in the engaging space 3 of the second link 101B, thereby achieving connection and locking of the two links.

[0107] As shown in Figure 6, when the lock buckle 2 is pressed in the direction P1 parallel to the thickness direction of the link (such as the direction H in Figure 6), the lock rod 1 can be withdrawn from the engaging space 3, the first opening 6 and the second opening 7, so that the first link 101A and the second link 101B are in the unlocked state, and the first link 101A and the second link 101B are separated as shown in Figure 7. It is understood that the link thickness direction can be the thickness direction of the watch strap.

[0108] When it is necessary to connect the first link 101A and the second link 101B, the end of the first link 101A with the locking rod 1 and the end of the second link 101B with the locking buckle 2 can be brought close to each other, and the locking rod 1 can pass through the second opening 7 and the first opening 6 in turn and be inserted into the clamping space 3 of the locking buckle 2 to achieve the locking of the first link 101A and the second link 101B.

[0109] The chain link quick-disassembly structure provided in the embodiment of the present application is not only simple in structure, but also convenient to operate when disassembling and assembling the chain links, and the user experience can be significantly improved.

[0110] In some examples, the locking rod 1 may be cylindrical or in other shapes, for example, the cross section of the locking rod 1 may be quadrilateral, elliptical, etc. The cross section of the locking rod 1 may be understood as a section perpendicular to the extension direction of the locking rod.

[0111] As shown in Figures 5 to 7, when the locking rod 1 is a cylindrical structure, the locking space 3 for accommodating the locking rod 1 may include a first space 31 with a fan-shaped cross section. When the two chain links are in a locked state, the locking rod 1 is located in the first space 31 with a fan-shaped cross section.

[0112] When the two links are locked, to reduce the risk of the locking rod 1 slipping out of the engaging space 3, as shown in Figure 7, the height h1 of the first space 31 can be greater than the radius r of the locking rod 1. This allows the majority of the locking rod 1 to be retained within the engaging space 3, improving the reliability of the connection between the locking rod 1 and the engaging space 3. The height h1 of the first space 31 shown in Figure 7 is parallel to the thickness of the link.

[0113] As shown in Figure 7, the locking space 3 also includes a second space 32, which is connected to the first space 31. When the lock buckle 2 is pressed, the locking rod 1 can slide from the first space 31 into the second space 32, and pass through the first opening 6 and the second opening 7 from the second space 32 in sequence to unlock the two chain links.

[0114] In some examples, as shown in FIG. 7 , the height dimension h2 of the second space 32 may be greater than the diameter 2r of the locking rod 1 .

[0115] In the examples shown in Figures 5 to 7, a chamber 5 for setting the lock buckle 2 can be opened in the chain link 101, and the lock buckle 2 is slidably installed in the chamber 5. In order to allow the locking rod 1 to be inserted into the clamping space 3 of the lock buckle 2, as shown in Figure 8, a first opening 6 connected to the clamping space 3 is opened on the lock buckle 2, and a second opening 7 connected to the chamber 5 is opened on the chain link 101.

[0116] In other examples, as shown in FIG9 , another configuration of the lock buckle 2 is illustrated. In this example, it is not necessary to provide a cavity 5 for arranging the lock buckle 2 within the link 101. The lock buckle 2 can be formed using a process such as injection molding, with the lock buckle 2 and the link 101 being an integral structural component. The lock buckle 2 can also be made of an elastic material such as a memory alloy. Referring to FIG9 and FIG10 , when the lock buckle 2 is pressed in the direction P1, the elastic deformation of the lock buckle 2 allows the locking rod 1 located in the engaging space 3 to pass through the first opening 6, thereby unlocking the two links.

[0117] After two adjacent links are separated using the chain link quick-release structure, for example, using the structure shown in Figures 5 to 7, the lock buckle 2 also needs to return to its initial position, that is, the lock buckle 2 needs to move in the direction opposite to the direction of P1.

[0118] In some embodiments, as shown in FIG. 11 , an elastic member 4 may be included, and the elastic member 4 is used to apply an elastic force to the lock buckle 2 in a direction P2 opposite to the direction P1 .

[0119] In one scenario, when the first link 101A and the second link 101B are in a locked state, the elastic force of the elastic member 4 on the lock buckle 2 along the P2 direction can be used to lock the lock rod 1 in the clamping space 3, thereby improving the connection reliability between the lock rod 1 and the lock buckle 2.

[0120] In the example of this application, as shown in Figure 11 , the movement direction of the buckle 2 is parallel to the thickness of the chain link. Chain link 101 has a first surface and a second surface facing each other, and at least a portion of the buckle 2 extends through the first surface into the chain link 101. For example, the buckle 2 can extend through the first surface facing away from the skin into the chain link, or through the first surface facing the skin into the chain link.

[0121] In order to improve the appearance of the wearable device and enhance the user experience, as shown in Figure 11, when the first link 101A and the second link 101B are in a locked state, the surface of the lock buckle 2 that is close to the skin can be flush with the outer wall surface of the link.

[0122] Continuing to refer to FIG. 11 , the wall surfaces of the lock buckle 2 used to enclose the engaging space 3 include: a first wall surface and a second wall surface facing the first wall surface.

[0123] When the first link 101A and the second link 101B are in the locked state as shown in Figure 11, the locking rod 1 abuts against the second wall. When the lock catch 2 moves in the direction P1 as shown in Figure 11, the locking rod moves in the direction P2 opposite to the direction P1. That is, the locking rod 1 moves relative to the lock catch 2 from the second wall toward the first wall.

[0124] When the two chain links are in the locked state, the locking rod 1 abuts against the wall surface forming the locking space, thus improving the connection reliability between the locking rod 1 and the lock buckle 2.

[0125] As shown in FIG. 11 , the wall surface of the lock buckle 2 used for surrounding the first opening 6 includes an opening wall surface, for example, the opening wall surface is connected to the first wall surface.

[0126] In some examples, the opening wall is an inclined surface, and when the engaging space 3 points toward the first opening 6 (direction T as shown in FIG11 ), the inclined surface slopes from the middle portion of the lock buckle 2 toward the edge. Alternatively, it can be understood that the opening wall includes a first end and a second end, the first end is closer to the second wall than the second end, and the distance from the first end to the first wall is shorter than the distance from the second end to the first wall.

[0127] When locking two links, the locking rod 1 can smoothly slide along the inclined surface into the engaging space 3 when passing through the first opening 6 from the second opening 7. Alternatively, when unlocking two links, the locking rod 1 can smoothly pass through the first opening 6 and the second opening 7 in sequence along the inclined surface, thereby improving the user experience.

[0128] The elastic member 4 in the example of the present application can be a spring as shown in the example of Figure 11, one end of the spring abuts on the chain link 101, and the other end abuts on the lock buckle 2. The spring is used to give the lock buckle 3 an elastic force along the P2 direction as shown in Figure 11. In this way, the first wall surface of the lock buckle 2 can be fitted on the locking rod 1, which improves the stability and reliability of the connection when the two chain links are in the locked state, and the locking rod 1 is not easy to slide out of the locking space 3.

[0129] When the lock buckle 2 is pushed in the direction P1 as shown in Figure 11, the spring can be compressed, and after the external force on the lock buckle 2 in the direction P1 disappears, the elastic force of the spring in the direction P2 can switch the two chain links to the locked state.

[0130] In some feasible structures, as shown in FIG12 , a receiving groove 8 can be provided on the lock buckle 2 , the depth of the receiving groove 8 being parallel to the thickness of the chain link, and the elastic member 4 is disposed in the receiving groove 8 . One end of the elastic member 4 abuts against the receiving groove 8 , and the other end abuts against the chain link 101 .

[0131] The placement groove 8 for setting the elastic member 4 in the example of this application can not only compress the thickness of the wearable device, but also play a limiting role, so that the elastic force of the elastic member 4 on the lock buckle 2 is along the P2 direction as shown in Figure 12.

[0132] The P1 direction and the P2 direction in the example of the present application may both be parallel to the thickness direction of the link, and the P1 direction (which may be referred to as the first direction) and the P2 direction (which may be referred to as the second direction) are opposite.

[0133] The locking rod 1 of the present application example has a variety of possible structures, two of which are exemplified below.

[0134] As shown in Figure 13, Figure 13 shows an exploded schematic diagram of a locking rod 1, a locking buckle 2 and a chain link 101. In this example, a locking rod 1 is included, and the locking rod 1 extends from one side of the chain link 101 to the other side.

[0135] It can be understood that along the width direction of the link 101 (the S direction as shown in FIG13 ), the link 101 has a first side and a second side, and the locking rod 1 extends from the first side to the second side.

[0136] As shown in FIG13 , on the link 101 , the second opening 7 for the locking rod 1 to pass through extends from the first side to the second side; on the lock buckle 2 , the first opening 6 for the locking rod 1 to pass through extends from the first side to the second side.

[0137] FIG14 shows another exploded schematic diagram of a locking rod 1, a locking buckle 2, and a chain link 101. In this example, the locking rod 1A and the second locking rod 1B are provided. The first locking rod 1A is provided on one side of the chain link 101, and the second locking rod 1B is provided on the other side of the chain link 101.

[0138] The structure shown in Figure 14 can be understood in this way: along the width direction of the chain link 101 (the S direction as shown in Figure 14), the chain link 101 has a first side and a second side, one end of the first locking rod 1A is connected to the first side, and the other end extends toward the second side, and one end of the second locking rod 1B is connected to the second side, and the other end extends toward the first side. In addition, the length dimensions of the first locking rod 1A and the second locking rod 1B are both smaller than the distance from the first side to the second side. Refer to Figure 15, which shows the connection relationship between the lock buckle 2, the first locking rod 1A and the second locking rod 1B. The snap-fitting space 3 in the lock buckle 2 includes: a first snap-fitting space 3A facing the first side, and a second snap-fitting space 3B facing the second side. The first snap-fitting space 3A is used to accommodate the first locking rod 1A, and the second snap-fitting space 3B is used to accommodate the second locking rod 1B.

[0139] As shown in Figure 16 , the lock buckle 2 includes a sub-opening 6A for the first locking rod 1A to pass through, and a sub-opening 6B for the second locking rod 1B to pass through. Returning to Figure 14 , the link 101 includes a sub-opening 7A for the first locking rod 1A to pass through, and a sub-opening 7B for the second locking rod 1B to pass through.

[0140] The first locking rod 1A can be inserted into the first engaging space 3A through the sub-opening 7A and the sub-opening 6A, respectively. The second locking rod 1B can be inserted into the second engaging space 3B through the sub-opening 7B and the sub-opening 6B, respectively. As shown in Figure 15 , in this embodiment, the tops of the first engaging space 3A and the second engaging space 3B are open to accommodate the corresponding first and second locking rods 1A and 1B. This reduces the thickness of the buckle, thereby reducing the thickness of the entire chain link.

[0141] It should be noted that Figure 14 illustrates the example in which the first locking rod 1A and the second locking rod 1B, the clamping space 3A and the clamping space 3B are at the same position in the thickness direction of the chain link, but this embodiment is not limited to this, and their positions in the thickness direction of the chain link may also be different.

[0142] In some other embodiments, the tops of the first engaging space 3A and the second engaging space 3B may also be closed.

[0143] As shown in Figure 16 , in this embodiment, the buckle 2 is provided with a receiving groove 8 for accommodating the elastic member 4. Because the locking bar 1 includes a first locking bar 1A and a second locking bar 1B that are independent of each other, the corresponding sub-openings 6A and 6B can be non-through, so that the first locking bar 1A, the second locking bar 1B, and the groove 8 are substantially aligned. This allows the buckle 2 to be compressed along the length of the watchband (e.g., the R direction in Figure 16 ).

[0144] In some optional structures, as shown in Figure 17, one end of the link 101 has a cavity 9 and the other end has a protrusion 10. In two connected links, the protrusion 10 of one link can be inserted into the cavity 9 of the other link to achieve the connection between the two links.

[0145] The locking rod 1 is disposed in the concave cavity 9 . For example, as shown in FIG. 17 , a mounting hole 11 may be provided on the link 101 , and the end of the locking rod 1 may be fixed in the mounting hole 11 .

[0146] In some other embodiments, the locking rod 1 and the chain link 101 may be integrally formed.

[0147] There are many optional structures for the locking rod 1. For example, as shown in Figure 18, along the length direction of the locking rod 1, the locking rod 1 includes a first section 111 and a second section 112 connected to each other. The radial dimension of the first section 111 is smaller than the radial dimension of the second section 112, that is, a step is formed at the connection between the first section 111 and the second section 112.

[0148] The second section 112 can be fixed in the mounting hole 11 of FIG. 17 , and the first section 111 can be inserted into the engaging space 3 of the lock buckle 2 .

[0149] Since the second section 112 is thicker than the first section 111 , the connection strength between the locking rod 1 and the chain link 101 can be improved.

[0150] In some examples, as shown in FIG18 , one of the two second segments 112 has teeth on its surface, which are used for interference fit with the mounting hole 11 , and the other second segment 112 may have a smooth surface and be clearance fit with the corresponding mounting hole.

[0151] In a feasible assembly process, the second section 112 with a smooth surface can first be passed through the two mounting holes in sequence, and the second section 112 with teeth is interference fit with the mounting holes to achieve the connection between the locking rod 1 and the chain link 101.

[0152] As shown in Figure 17, the lock buckle 2 is set in the protrusion 10. For example, as shown in Figure 19, a through hole 15 can be opened on one side of the protrusion 10. The through hole 15 is connected to the cavity 5 in the protrusion 10, and the lock buckle 2 can be set in the cavity 5 through the through hole 15.

[0153] In some possible configurations, the lock buckle 2 can be detachably mounted on the link 101 to facilitate replacement and maintenance of the lock buckle 2. As shown in FIG17 , the lock buckle 2 is disposed within the cavity 5 of the protrusion 10. A first mounting hole 13 can be defined on the wall of the link 101 that defines the recessed cavity 9, and a second mounting hole 14 can be defined on the lock buckle 2. The first mounting hole 13 communicates with the second mounting hole 14, and a latch 12 can extend through the first mounting hole 13 and into the second mounting hole 14, thereby connecting the lock buckle 2 to the link 101.

[0154] In addition, the lock buckle 2 of the present application can also move along the thickness direction of the chain link. The second mounting hole 14 provided on the lock buckle 2 can be a strip-shaped structure. The extension direction of the second mounting hole 14 of the strip-shaped structure can be parallel to the thickness direction of the chain link. In this way, when the lock buckle 2 is pressed, the lock buckle 2 can move along the extension direction of the second mounting hole 14.

[0155] The second mounting hole 14 cooperates with the latch 12, which can not only connect the lock buckle 2 with the chain link 101, but also play a limiting role. The size of the second mounting hole 14 in the extension direction can be designed according to the moving distance of the lock buckle 2. The latch 12 has the function of a limiting column, and the second mounting hole 14 of the strip structure has the function of a limiting groove.

[0156] In some other embodiments, the second mounting hole 14 provided on the lock buckle 2 may be a circular hole as shown in FIG17 , wherein the diameter of the circular hole is larger than the diameter of the pin 12 inserted into the circular hole. In this way, when the lock buckle 2 is pressed, the lock buckle 2 may also move in the second mounting hole 14 along the thickness direction of the chain link.

[0157] 17 and 19 , the lock buckle 2 passes through the through hole 15, and the through hole 15 can limit the lock buckle 2 along the width direction of the chain link (such as the S direction in FIG19 ). Therefore, even if the second mounting hole 14 adopts the circular hole shown in FIG17 , when the lock buckle 2 moves along the thickness direction of the chain link, it will basically not move in the width direction of the chain link.

[0158] Figure 20 shows the disassembled chain link 101, the lock buckle 2, the first locking rod 1A, and the second locking rod 1B, when the chain link 101 includes the first locking rod 1A and the second locking rod 1B. In this example, the chain link 101 has a cavity 9 at one end and a protrusion 10 at the other end. The protrusion 10 of one of the two connected chain links can be inserted into the cavity 9 of the other link, thus connecting the two links.

[0159] The locking rod 1 is arranged in the concave cavity 9. For example, as shown in Figure 20, a mounting hole 11A and a mounting hole 11B can be opened on the chain link 101, and the end of the first locking rod 1A can be fixed in the mounting hole 11A, and the end of the second locking rod 1B can be fixed in the mounting hole 11B.

[0160] As shown in Figure 19, the lock buckle 2 is set in the cavity 5 of the protrusion 10, and a first mounting hole 13 can be opened on the wall surface of the chain link 101 for enclosing the concave cavity 9, and a second mounting hole 14 can be opened on the lock buckle 2. The first mounting hole 13 is connected to the second mounting hole 14, and the pin 12 can pass through the first mounting hole 13 and extend into the second mounting hole 14, thereby connecting the lock buckle 2 to the chain link 101.

[0161] As shown in Figure 20, the second mounting hole 14 provided on the lock buckle 2 can be a circular hole, the diameter of which is larger than the diameter of the pin 12 inserted into the circular hole. In this way, when the lock buckle 2 is pressed, the lock buckle 2 can also move in the second mounting hole 14 along the thickness direction of the chain link.

[0162] When the lock buckle 2 adopts the example shown in Figures 13 and 20, the elastic member 4 can be first installed in the groove 8 of the lock buckle 2, and then the lock buckle 2 is passed through the through hole 15 shown in Figure 19, and then the pin 12 is passed through the first mounting hole 13 and the second mounting hole 14 in sequence, thereby connecting the lock buckle 2 to the chain link 101.

[0164] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application.
