Description

Technical Field

[0001] This application relates to the technical field of wearable devices, and in particular, to a wearable device, a watch band that can be applied to the wearable device, and a watch band link assembly that can be applied to the watch band. Background Art

[0002] Wearable devices generally refer to miniature electronic devices that can be worn on the body for activities, and basically include smart watches and smart bracelets. Smart watches and smart bracelets can be used independently or as portable accessories for mobile terminals.

[0003] Wearable devices mainly include a watch face and a watch band. The watch band includes a plurality of sequentially connected links. Most of the adjacent two links are fixed or not easily disassembled quickly, which brings inconvenience to the adjustment of the watch band length. Summary of the Invention

[0004] This application provides a wearable device, a watch band that can be applied to the wearable device, and a watch band link assembly that can be applied to the watch band. The purpose is to provide a structure that can quickly disassemble the watch band link.

[0005] To achieve the above object, the embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, this application provides a watch band that can be applied to a wearable device. For example, the wearable device can be a watch or a bracelet.

[0007] The watch band provided by this application includes a plurality of sequentially connected links. The plurality of links include 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, and the extending 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 communicating with the clamping space are provided in the locking buckle.

[0008] When the locking 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 link and the second link, so that the first link and the second link are in a locked state.

[0009] When the locking buckle moves along the thickness direction of the second link, the locking rod can be detached from the clamping space and the first opening, disassembling the first link and the second link, so that the first link and the second link are in an unlocked state.

[0010] When it is necessary to shorten the length of the watch band and disassemble some links, for example, when disassembling the first connected link and the second link, the 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 exit from the clamping space and the first opening of the second link to achieve unlocking, so that the first link and the second link are in a separated state.

[0011] Alternatively, when it is necessary to connect the first link and the second link, the end of the second link with the buckle and the end of the first link with the locking rod approach each other. The locking rod can pass through the first opening and insert into the clamping space to achieve the locking of the first link and the second link.

[0012] In the watch band exemplified in this application, not only is the disassembly and assembly structure simple, but the operation is also convenient when disassembling and assembling the links. The links can be disassembled and assembled quickly, improving the user experience.

[0013] In an implementable way, the second link further has a chamber and a second opening communicating with the chamber. The second opening communicates with the first opening, and the buckle is arranged in the chamber. For example, the buckle is slidably arranged in the chamber and slides along the thickness direction of the link.

[0014] In an implementable way, the locking rod of the first link can sequentially pass through the second opening of the second link, the first opening and be located in the clamping space. The locking rod is connected to the buckle, so that the first link and the second link are in a locked state; when the buckle moves along the thickness direction of the link, the locking rod sequentially exits from the clamping space, the first opening and the second opening, and the locking rod is disassembled from the buckle, so that the first link and the second link are in an unlocked state.

[0015] In this example, a chamber is provided in the link, and the buckle is slidably arranged in the chamber. In order to enable the locking rod to exit from the chamber, a second opening communicating with the chamber is also provided on the link. In this way, the locking rod can pass through the second opening and the first opening and insert into the clamping space.

[0016] In an implementable way, an elastic member is arranged in the chamber. The elastic member connects the buckle and the second link; when the first link and the second link are connected, the elastic member is used to apply an elastic force to the buckle along the thickness direction of the second link.

[0017] By using the elastic force of the elastic member on the buckle, when the first link and the second link are in a locked state, the locking rod can be continuously and stably locked in the clamping space, improving the locking reliability.

[0018] In an implementable manner, a placement groove is formed in the latch. The depth direction of the placement groove is parallel to the thickness direction of the second link. At least a part of the elastic member is disposed in the placement groove. One end of the elastic member abuts against the second link, and the other end abuts against the latch. After the external force acting on the latch along the thickness direction of the link and towards the inside of the link disappears, the elastic force of the elastic member can cause the first link and the second link to switch to the locked state.

[0019] By forming a placement groove in the latch with its depth direction parallel to the thickness direction of the link and disposing the elastic member in the placement groove, not only can the thickness dimension of the entire link be compressed, but the placement groove can also play a limiting role, enabling the elastic force of the elastic member on the latch to be substantially parallel to the thickness direction of the link.

[0020] In an implementable manner, the wall surface of the latch for enclosing the clamping space includes: 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 latch moves in the first direction, the locking rod moves in the second direction opposite to the first direction, and the first direction points from the first wall surface to the second wall surface.

[0021] When the first link and the second link are in the locked state, since the locking rod abuts against the wall surface, the stable reliability when the two links are locked can be improved.

[0022] In an implementable manner, the wall surface of the latch for enclosing the first opening includes an opening wall surface. For example, the opening wall surface is connected to the second wall surface, and the opening wall surface 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 surface than the second end; the distance from the first end to the first wall surface is less than the distance from the second end to the first wall surface.

[0023] Since one wall surface of the opening is set as an inclined surface, in this way, the locking rod can slide into the clamping space of the latch along the inclined surface more easily, or the locking rod located in the clamping space can also slide out along the inclined surface more easily, improving the user experience of locking and unlocking.

[0024] In an implementable manner, the second link further includes a limiting structure for limiting the distance that the latch moves along the thickness direction of the second link.

[0025] In an implementable manner, the limiting structure includes: a limiting groove and a limiting post slidably disposed in the limiting groove. The extending direction of the limiting groove is parallel to the thickness direction of the second link; one of the limiting groove and the limiting post is disposed on the second link, and the other is disposed on the latch.

[0026] By using a limiting groove and a limiting post with a simple structure, the moving distance of the lock catch along the thickness direction of the chain link can be limited, so that the lock rod can slide into the clamping space of the lock catch more precisely, realizing the locking connection of two chain links.

[0027] In a feasible way, along the width direction of the first chain link, the first chain link has a first side and a second side, and the lock rod extends from the first side to the second side; the first opening extends from the first side to the second side.

[0028] In this implementation structure, it includes a lock rod, and this lock rod can slide into the clamping space of the lock catch through the first opening.

[0029] In a feasible way, along the width direction of the first chain link, the first chain link has a first side and a second side; the lock rod includes a first lock rod and a second lock rod. One end of the first lock rod is connected to the first side, and the other end extends towards the second side. One end of the second lock rod is connected to the second side, and the other end extends towards the first side; the clamping space in the lock catch includes: a first clamping space facing the first side and a second clamping space facing the second side. The first clamping space is used to accommodate the first lock rod, and the second clamping space is used to accommodate the second lock rod.

[0030] In this embodiment, it includes two lock rods, and the two lock rods can be symmetrically arranged, and correspondingly, two clamping spaces are arranged.

[0031] In a feasible way, the first chain link includes a concave cavity, the lock rod is arranged in the concave cavity, the second chain link includes a protruding part, and the lock catch is arranged in the protruding part; when the first chain link and the second chain link are connected, the protruding part is located in the concave cavity.

[0032] In a feasible way, a first mounting hole is opened on the wall surface of the first chain link for enclosing the concave cavity, a second mounting hole is opened on the lock catch, and the pin passes through the first mounting hole and extends into the second mounting hole.

[0033] In a feasible way, the radial dimension of the part of the pin extending into the second mounting hole is smaller than the aperture of the second mounting hole.

[0034] In this example, the pin can not only realize the detachable connection between the lock catch and the chain link, facilitating the disassembly and assembly of the lock catch; in addition, by using the sliding fit between the pin and the second mounting hole, the moving distance of the lock catch along the thickness direction of the chain link can be limited, improving the matching precision between the lock rod and the lock catch.

[0035] In a feasible way, along the thickness direction of the second chain link, the second chain link has a first surface and a second surface facing each other, the first surface is closer to the skin than the second surface, and a through hole is opened on the first surface, and at least part of the lock catch passes through the through hole and extends into the second chain link.

[0036] In some examples, the surface of the buckle that is close to the skin is flush with the first surface of the first link.

[0037] In a second aspect, the present application provides a wearable device, which includes a watch face and a watch band in any of the above implementation manners, and the watch band is connected to the watch face.

[0038] Since the wearable device includes a watch band in any of the above implementation manners, in the watch band, through the cooperation of the buckle and the locking rod, the quick disassembly and assembly of adjacent links can be achieved. For example, when it is necessary to disassemble a link, the buckle can be pressed, and the locking rod can be withdrawn from the clamping space of the buckle to unlock two adjacent links; for another example, when it is necessary to connect links, the two links can be brought close to each other, and the locking rod can slide into the clamping space of the buckle to lock the two links. The structure for quickly disassembling the link is simple, and the disassembly and assembly are also convenient.

[0039] In a third aspect, the present application provides a watch band link assembly, which includes a link. A locking rod is provided at one end of the link, and a buckle is provided at the other end. The extending direction of the locking rod is parallel to the width direction of the link, and a clamping space and a first opening communicating with the clamping space are provided in the buckle.

[0040] When the 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 buckle and the locking rod, so that the link and the other link are in a locked state; when the buckle of the other link moves along the thickness direction of the link, the locking rod can be disassembled from the clamping space and the first opening to disassemble the link and the other link, so that the link and the other link are in an unlocked state.

[0041] Applying this watch band link assembly to the watch band can achieve the quick disassembly and assembly of two adjacent links. In addition, the structure for achieving the quick disassembly and assembly is relatively simple. For example, pressing the buckle can unlock the two links, and when the two links are brought close to each other and the locking rod is inserted into the clamping space of the buckle, the two links can be locked together, and the operation is simple, which can improve the user experience.

[0042] In a realizable manner, a chamber and a second opening communicating with the chamber are further provided in the link. The second opening communicates with the first opening, and the buckle is provided in the chamber.

[0043] The locking rod of the link can pass through the second opening and the first opening of another link in sequence and be located in the clamping space, so that the link and the other link are in a locked state; when the buckle moves along the thickness direction of the link, the locking rod withdraws from the clamping space, the first opening and the second opening, so that the link and the other link are in an unlocked state.

[0044] A chamber is provided within the link, and the latch is slidably disposed within the chamber. A second opening communicating with the chamber is also provided on the link. In this way, the locking rod can pass through the second opening and the first opening and be inserted into the clamping space.

[0045] In an implementable manner, an elastic member is provided within the chamber, and the elastic member connects the latch and the link; when the link is connected to another link, the elastic member is used to apply an elastic force to the latch in the thickness direction of the link.

[0046] By utilizing the elastic force of the elastic member on the latch, the connection stability between the locking rod and the latch when in the locked state can be improved.

[0047] In an implementable manner, the latch is made of an elastic material. For example, it can be made of a shape memory alloy material.

[0048] In an implementable manner, the watch band link assembly further includes a limiting structure for limiting the distance that the latch moves in the thickness direction of the link.

[0049] In this way, the locking rod can slide more precisely into the clamping space of the latch.

[0050] In an implementable manner, the limiting structure includes: a limiting groove and a limiting post slidably disposed within the limiting groove. The extending direction of the limiting groove is parallel to the thickness direction of the link; one of the limiting groove and the limiting post is provided on the link, and the other is provided on the latch.

[0051] In an implementable manner, the wall surface of the latch for enclosing the clamping space includes: a first wall surface and a second wall surface facing the first wall surface face to face; when the link is connected to another link, the locking rod abuts against the second wall surface; when the latch moves in the first direction, the locking rod moves in the second direction opposite to the first direction, and the first direction points from the first wall surface to the second wall surface.

[0052] When the two links are in the locked state, the locking rod abuts against one wall surface of the clamping space, which can improve the stability and reliability.

[0053] In an implementable manner, the wall surface of the latch for enclosing 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 less than the distance from the second end to the first wall surface.

[0054] The locking rod can slide more easily into the clamping space of the latch along this inclined surface. Or, the locking rod located within the clamping space can also slide out more easily along this inclined surface, improving the user experience of locking and unlocking.

[0055] In one possible implementation, along the width direction of the link, the link has a first side and a second side, and the locking rod extends from the first side to the second side; the first opening extends from the first side to the second side.

[0056] In this implementation structure, it includes a locking rod, and the corresponding first opening is also an opening that penetrates the first side and the second side.

[0057] In one possible implementation, along the width direction of the link, the 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 towards the second side. One end of the second locking rod is connected to the second side, and the other end extends towards the first side; the clamping space in the lock buckle includes: a first clamping space facing the first side and a second clamping space facing the second side. The first clamping space is used to accommodate the first locking rod, and the second clamping space is used to accommodate the second locking rod.

[0058] In this implementation structure, it includes two locking rods.

[0059] In one possible implementation, one end of the link includes a concave cavity, and the other end includes a protruding portion. The locking rod is arranged in the concave cavity, and the lock buckle is arranged in the protruding portion; when the link is connected to another link, the protruding portion is located in the concave cavity.

[0060] In one possible implementation, a first mounting hole is formed on the wall surface of the link for enclosing the concave cavity, and a second mounting hole is formed on the lock buckle. The pin passes through the first mounting hole and extends into the second mounting hole.

[0061] In one possible implementation, the radial dimension of the part of the pin extending into the second mounting hole is smaller than the aperture of the second mounting hole.

[0062] In this example, the pin can not only realize the detachable connection between the lock buckle and the link, facilitating the disassembly and assembly of the lock buckle; in addition, by using the sliding fit between the pin and the second mounting hole, the moving distance of the lock buckle along the thickness direction of the link can be limited, improving the matching accuracy between the locking rod and the lock buckle.

[0092] An embodiment of the present application provides a wearable device. For example, the wearable device can be a smart bracelet or a smart watch. The wearable device can be worn on the wrist to implement functions such as time display, timekeeping, time reporting, message notification, motion detection, heart rate monitoring, blood oxygen level detection, etc.

[0093] The wearable device can include a watch band and a watch face. The watch band is used to surround the user's wrist to achieve the wearing of the wearable device, and the watch face is used for display.

[0094] Such as Figure 1 and Figure 2 , Figure 1 and Figure 2 Exemplarily show the structure diagram of a watch band of a wearable device. The exemplary watch band 100 includes a plurality of links 101 connected in sequence. The exemplary watch band 100 can be a metal or ceramic watch band.

[0095] In order to make the length of the watch band adjustable, some of the adjacent two link sections 101 may be detachably connected. In this way, the user can remove some link sections 101 according to the usage needs to shorten the length of the watch band; or add some link sections 101 to extend the length of the watch band, so as to accurately fit the wrist and improve the user experience.

[0096] In order to quickly and conveniently disassemble and assemble the link sections, the present application exemplarily provides a link section quick-release structure, and the achievable structure of the link section quick-release structure is as follows.

[0097] Such as Figure 3 and Figure 4 , Figure 3 is a structural diagram of one of the link sections in a watch band exemplified in the present application, Figure 4 is Figure 3 exploded view of.

[0098] Combined with Figure 3 and Figure 4 , one end of the link section 101 is provided with a locking rod 1, the other end has a locking buckle 2, a clamping space 3 is arranged in the locking buckle 2, and a first opening 6 communicated with the clamping space 3.

[0099] In the example of the present application, the extending direction of the locking rod 1 is parallel to the width direction of the link section 101 (such as Figure 4 S direction in). The locking buckle 2 can move along the thickness direction of the link section 101 (such as Figure 4 H direction in). It can be understood that the width direction of the link section 101 can be the width direction of the watch band 100.

[0100] In some examples, a chamber 5 may be arranged at the end of the link section 101 where the locking buckle 2 is arranged, and the locking buckle 2 is slidably arranged in the chamber 5. The link section 101 may also be provided with a second opening 7 communicated with the chamber 5.

[0101] In the embodiment of the present application, one end of the link section 101 where the locking rod 1 is arranged may be close to the end of another link section, and the other end of the link section 101 where the locking buckle 2 is arranged may be close to the end of yet another link section.

[0102] In the watch band exemplified in the present application, some adjacent link sections can be connected and disassembled, so that they can be switched between the locked state and the unlocked state. In the example of the present application, two adjacent link sections are connected and in the locked state, and two adjacent link sections are disassembled and in the unlocked state.

[0103] Such as Figure 5 , Figure 6 and Figure 7 , Figures 5 to 7 respectively show the corresponding structural diagrams when two adjacent link sections are in the locked state and the unlocked state. Figure 5The structural diagram when the first link 101A and the second link 101B shown are in the locked state Figure 6 The structural diagram when the first link 101A and the second link 101B are shown when the lock buckle 2 is pressed Figure 7 The structural diagram when the first link 101A and the second link 101B are in the unlocked state

[0104] As Figure 5 , the locking rod 1 of the first link 101A is located in the clamping space 3 of the second link 101B to realize the connection and locking of the two links

[0105] As Figure 6 , when pressing the lock buckle 2 in the P1 direction along the direction parallel to the link thickness direction (such as Figure 6 the H direction), the locking rod 1 can exit from the clamping 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, realizing the splitting of the first link 101A and the second link 101B as shown in Figure 7 . It can be understood that the link thickness direction can be the thickness direction of the watch band

[0106] 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 lock buckle 2 can be made to approach each other. The locking rod 1 can sequentially pass through the second opening 7 and the first opening 6 and be inserted into the clamping space 3 of the lock buckle 2 to realize the locking of the first link 101A and the second link 101B

[0107] The link quick-release structure given in the embodiment of the present application not only has a simple structure, but also is very convenient to operate when disassembling and assembling the link, and the user experience can be significantly improved

[0108] In some examples, the locking rod 1 can be a cylindrical structure, or it can be other shapes. For example, the cross-section of the locking rod 1 is a quadrilateral, an ellipse, etc. The cross-section of the locking rod 1 can be understood as the section perpendicular to the extending direction of the locking rod

[0109] As Figures 5 to 7 , when the locking rod 1 is a cylindrical structure, the clamping space 3 for accommodating the locking rod 1 can include a first space 31 with a fan-shaped cross-section. When the two links are in the locked state, the locking rod 1 is located in the first space 31 with a fan-shaped cross-section

[0110] When the two links are in the locked state, in order to reduce the risk of the locking rod 1 slipping out of the clamping space 3, as Figure 7 shown, the height dimension h1 of the first space 31 can be greater than the radius r of the locking rod 1, so that most of the structure of the locking rod 1 is stuck in the clamping space 3, improving the connection reliability between the locking rod 1 and the clamping space 3Figure 7 The height dimension h1 of the first space 31 of the example is the dimension in the direction parallel to the thickness of the link.

[0111] Such as Figure 7 , the clamping space 3 further includes a second space 32. The second space 32 communicates with the first space 31. When the latch 2 is pressed, the locking rod 1 can slide from the first space 31 into the second space 32 and sequentially pass through the first opening 6 and the second opening 7 from the second space 32 to realize the unlocking of the two links.

[0112] In some examples, such as Figure 7 , the height dimension h2 of the second space 32 can be greater than the diameter 2r of the locking rod 1.

[0113] In Figures 5 to 7 the shown example, a chamber 5 for arranging the latch 2 can be opened in the link 101. The latch 2 is slidably installed in the chamber 5. In order to enable the locking rod 1 to be inserted into the clamping space 3 of the latch 2, as Figure 8 shown, a first opening 6 communicating with the clamping space 3 is opened on the latch 2, and a second opening 7 communicating with the chamber 5 is opened on the link 101.

[0114] In some other examples, such as Figure 9 shown, Figure 9 another setting method of the latch 2 is shown. In this example, it may not be necessary to open a chamber 5 for arranging the latch 2 in the link 101. The latch 2 can adopt some processes, for example, injection molding process. The latch 2 and the link 101 are an integral structural part. The latch 2 can also be made of an elastic material, for example, a shape memory alloy material. Combining Figure 9 and Figure 10 , when the latch 2 is pressed along the P1 direction, by using the elastic deformation of the latch 2, the locking rod 1 located in the clamping space 3 can pass through the first opening 6 to realize the unlocking of the two links.

[0115] After splitting two adjacent links by using the link quick-release structure, for example, adopting the Figures 5 to 7 shown structure, the latch 2 still needs to return to the initial position, that is, the latch 2 needs to move in the direction opposite to the P1 direction.

[0116] In some embodiments, such as Figure 11 , an elastic member 4 can be included. The elastic member 4 is used to apply an elastic force to the latch 2 in the P2 direction opposite to the P1 direction.

[0117] In a scenario, such as when the first link 101A and the second link 101B are in a locked state, by using the elastic force of the elastic member 4 on the latch 2 in the P2 direction, the locking rod 1 can be locked in the clamping space 3 to improve the connection reliability between the locking rod 1 and the latch 2.

[0118] In the example of this application, see Figure 11 , the moving direction of the latch 2 is parallel to the thickness direction of the link. The link 101 has a first surface and a second surface facing each other, and at least a part of the latch 2 extends through the first surface into the link 101. For example, the latch 2 can extend through the first surface facing away from the skin into the link, or the latch 2 can extend through the first surface close to the skin into the link.

[0119] To improve the aesthetic appearance of the wearable device and enhance the user experience, such as Figure 11 , when the first link 101A and the second link 101B are in the locked state, the surface of the latch 2 for being close to the skin can be flush with the outer wall surface of the link.

[0120] Continue to refer to Figure 11 , the wall surface of the latch 2 for enclosing the clamping space 3 includes: a first wall surface and a second wall surface facing the first wall surface.

[0121] When the first link 101A and the second link 101B are in the locked state as shown in Figure 11 , the locking lever 1 abuts against the second wall surface. When the latch 2 moves along the P1 direction shown in Figure 11 , the locking lever moves along the P2 direction opposite to the P1 direction, that is, the locking lever 1 moves relative to the latch 2 from the second wall surface towards the first wall surface.

[0122] Since when the two links are in the locked state, the locking lever 1 abuts against the wall surface forming the clamping space, in this way, the connection reliability between the locking lever 1 and the latch 2 can be improved.

[0123] See Figure 11 , the wall surface of the latch 2 for enclosing the first opening 6 includes an opening wall surface. For example, the opening wall surface is connected to the first wall surface.

[0124] In some examples, the opening wall surface is an inclined surface, and in the direction from the clamping space 3 to the first opening 6 (the T direction shown in Figure 11 ), the inclined surface inclines from the middle of the latch 2 towards the edge direction. Or, it can be understood that: the opening wall surface includes a first end and a second end, the first end is closer to the second wall surface than the second end, and the distance from the first end to the first wall surface is less than the distance from the second end to the first wall surface.

[0125] When it is necessary to lock the two links, when the locking lever 1 passes through the first opening 6 from the second opening 7, it can smoothly slide into the clamping space 3 along the inclined surface. Or, when it is necessary to unlock the two links, the locking lever 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.

[0126] The elastic member 4 in the example of this application can be such asFigure 11 An exemplary spring has one end abutted against the link 101 and the other end abutted against the latch 2. The spring is used to apply an elastic force to the latch 3 in the P2 direction as shown in Figure 11 . In this way, the first wall surface of the latch 2 can be fitted against the locking rod 1, improving the connection stability and reliability when the two links are in the locked state, and the locking rod 1 is not likely to slip out of the clamping space 3.

[0127] When the latch 2 is pushed in the P1 direction as shown in Figure 11 , the spring can be compressed. Moreover, after the external force on the latch 2 in the P1 direction disappears, the elastic force of the spring in the P2 direction can make the two links switch to the locked state.

[0128] In some realizable structures, as shown in Figure 12 , an installation groove 8 can be formed on the latch 2. The depth direction of the installation groove 8 is parallel to the thickness direction of the link, and the elastic member 4 is arranged in the installation groove 8. One end of the elastic member 4 abuts against the inside of the installation groove 8, and the other end abuts against the link 101.

[0129] The installation groove 8 for arranging the elastic member 4 in the example of the present application can not only compress the thickness dimension of the wearable device, but also play a limiting role, making the elastic force of the elastic member 4 on the latch 2 along the P2 direction as shown in Figure 12 .

[0130] In the example of the present application, both the P1 direction and the P2 direction can be parallel to the thickness direction of the link, and the P1 direction (which can be called the first direction) and the P2 direction (which can be called the second direction) are opposite.

[0131] The locking rod 1 in the example of the present application has various realizable structures, and two of them are exemplarily shown below.

[0132] As shown in Figure 13 , Figure 13 shows an exploded view of a locking rod 1, a latch 2 and a link 101. In this example, there is one locking rod 1 that extends from one side of the link 101 to the other side.

[0133] It can be understood in this way: along the width direction of the link 101 (the S direction as shown in Figure 13 ), 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.

[0134] See Figure 13 . 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 latch 2, the first opening 6 for the locking rod 1 to pass through extends from the first side to the second side.

[0135] As shown in Figure 14 ,Figure 14 Shows an exploded view of another lock lever 1, lock catch 2 and link 101. In this example, it includes a first lock lever 1A and a second lock lever 1B. The first lock lever 1A is arranged on one side of the link 101, and the second lock lever 1B is arranged on the other side of the link 101.

[0136] It can be understood in this way Figure 14 For the structure shown, along the width direction of the link 101 (such as Figure 14 the S direction shown), the link 101 has a first side and a second side. One end of the first lock lever 1A is connected to the first side, and the other end extends towards the second side. One end of the second lock lever 1B is connected to the second side, and the other end extends towards the first side. And, the length dimensions of the first lock lever 1A and the second lock lever 1B are both smaller than the distance from the first side to the second side. Refer to Figure 15 , Figure 15 Shows the connection relationship between the lock catch 2, the first lock lever 1A and the second lock lever 1B. The clamping space 3 in the lock catch 2 includes: a first clamping space 3A facing the first side, and a second clamping space 3B facing the second side. The first clamping space 3A is used to accommodate the first lock lever 1A, and the second clamping space 3B is used to accommodate the second lock lever 1B.

[0137] Such as Figure 16 , on the lock catch 2, it includes a sub-opening 6A for the first lock lever 1A to pass through, and includes a sub-opening 6B for the second lock lever 1B to pass through. Return to Figure 14 , on the link 101, it includes a sub-opening 7A for the first lock lever 1A to pass through, and includes a sub-opening 7B for the second lock lever 1B to pass through.

[0138] The first lock lever 1A can sequentially pass through the sub-opening 7A and the sub-opening 6A and be inserted into the first clamping space 3A, and the second lock lever 1B can sequentially pass through the sub-opening 7B and the sub-opening 6B and be inserted into the second clamping space 3B. Such as Figure 15 , in this embodiment, the tops of the first clamping space 3A and the second clamping space 3B are open to accommodate the corresponding first lock lever 1A and second lock lever 1B. In this way, the thickness dimension of the lock catch can be compressed, thereby reducing the thickness dimension of the entire link.

[0139] It should be noted that Figure 14 The description is made by taking the positions of the first lock lever 1A and the second lock lever 1B, the clamping space 3A and the clamping space 3B being the same in the thickness direction of the link as an example, but this embodiment is not limited to this, and their positions in the thickness direction of the link can also be different.

[0140] In some other embodiments, the tops of the first clamping space 3A and the second clamping space 3B can also be closed.

[0141] Such as Figure 16, in this embodiment, a placement groove 8 for arranging an elastic member 4 is formed on the buckle 2. Since the locking rod 1 includes a first locking rod 1A and a second locking rod 1B that are independent of each other, the corresponding sub-openings 6A and sub-openings 6B may not penetrate, such that the first locking rod 1A, the second locking rod 1B, and the groove 8 are substantially on the same straight line. In this way, the dimension of the buckle 2 in the length direction of the watchband (such as the R direction in Figure 16 can be compressed.

[0142] In some alternative structures, as shown in Figure 17 , one end of the link 101 has a concave 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 concave cavity 9 of the other link to realize the connection of the two links.

[0143] The locking rod 1 is arranged in the concave cavity 9. For example, as shown in Figure 17 , an installation hole 11 can be formed on the link 101, and the end of the locking rod 1 can be fixed in the installation hole 11.

[0144] In some other embodiments, the locking rod 1 and the link 101 can be an integrally formed structure.

[0145] There are various alternative 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 connected first section 111 and a second section 112. 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.

[0146] The second section 112 can be fixed in the installation hole 11 shown in Figure 17 , and the first section 111 can be inserted into the clamping space 3 of the buckle 2.

[0147] Since the second section 112 is thicker than the first section 111, the connection strength between the locking rod 1 and the link 101 can be improved in this way.

[0148] In some examples, as shown in Figure 18 , among the two second sections 112, the surface of one second section 112 has teeth, and the teeth are in interference fit with the installation hole 11. The surface of the other second section 112 can be a smooth surface and is in clearance fit with the corresponding installation hole.

[0149] In the achievable assembly process, first, the second section 112 with a smooth surface can be passed through the two installation holes in sequence, and the second section 112 with teeth is in interference fit with the installation hole to realize the connection between the locking rod 1 and the link 101.

[0150] As shown in Figure 17 , the buckle 2 is arranged in the protrusion 10. For example, as shown inFigure 19 , a through hole 15 can be formed on one side surface of the protruding portion 10, and the through hole 15 communicates with the chamber 5 inside the protruding portion 10. The latch 2 can be disposed in the chamber 5 through the through hole 15.

[0151] In some realizable structures, the latch 2 is detachably mounted on the link 101 to facilitate the replacement and repair of the latch 2. For example, Figure 17 , the latch 2 is disposed in the chamber 5 of the protruding portion 10. A first mounting hole 13 can be formed on the wall surface of the link 101 for enclosing the concave cavity 9, and a second mounting hole 14 is formed on the latch 2. The first mounting hole 13 communicates with the second mounting hole 14. The pin 12 can extend through the first mounting hole 13 into the second mounting hole 14, thereby connecting the latch 2 with the link 101.

[0152] In addition, the latch 2 of the present application example can also move along the thickness direction of the link. The second mounting hole 14 formed on the latch 2 can be a strip structure. The extending direction of the strip-structured second mounting hole 14 can be parallel to the thickness direction of the link. In this way, when the latch 2 is pressed, the latch 2 can move along the extending direction of the second mounting hole 14.

[0153] The cooperation between the second mounting hole 14 and the pin 12 can not only connect the latch 2 with the link 101, but also play a limiting role. The dimension in the extending direction of the second mounting hole 14 can be designed according to the moving distance of the latch 2. The pin 12 functions as a limiting post, and the strip-structured second mounting hole 14 functions as a limiting groove.

[0154] In some other embodiments, the second mounting hole 14 formed on the latch 2 can be a Figure 17 circular hole as shown. The diameter of the circular hole is larger than the diameter of the pin 12 extending into the circular hole. In this way, when the latch 2 is pressed, the latch 2 can also move along the thickness direction of the link in the second mounting hole 14.

[0155] Combined with Figure 17 and Figure 19 , the latch 2 passes through the through hole 15, and the through hole 15 can play a limiting role on the latch 2 along the width direction of the link (such as Figure 19 the S direction in the figure). Thus, even if the second mounting hole 14 adopts a Figure 17 circular hole as shown, when the latch 2 moves along the thickness direction of the link, it basically does not move in the width direction of the link.

[0156] For example, Figure 20 , Figure 20Shown is the intention of the disassembly of the link 101, the buckle 2, the first locking lever 1A, and the second locking lever 1B when the first locking lever 1A and the second locking lever 1B are included. In this example, one end of the link 101 has a concave 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 concave cavity 9 of the other link to realize the connection of the two links.

[0157] The locking lever 1 is arranged in the concave cavity 9. For example, Figure 20 , mounting holes 11A and 11B can be formed on the link 101. The end of the first locking lever 1A can be fixed in the mounting hole 11A, and the end of the second locking lever 1B can be fixed in the mounting hole 11B.

[0158] For example, Figure 19 , the buckle 2 is arranged in the cavity 5 of the protrusion 10. A first mounting hole 13 can be formed on the wall surface of the link 101 for enclosing the concave cavity 9, and a second mounting hole 14 can be formed on the buckle 2. The first mounting hole 13 communicates with the second mounting hole 14. The pin 12 can pass through the first mounting hole 13 and extend into the second mounting hole 14, thereby connecting the buckle 2 with the link 101.

[0159] For example, Figure 20 , the second mounting hole 14 formed on the buckle 2 can be a round hole, and the diameter of the round hole is larger than the diameter of the pin 12 extending into the round hole. In this way, when the buckle 2 is pressed, the buckle 2 can also move in the second mounting hole 14 along the thickness direction of the link.

[0160] When the buckle 2 adopts the Figure 13 and Figure 20 shown examples, the elastic member 4 can be first installed in the groove 8 of the buckle 2, and then the buckle 2 is passed through the Figure 19 shown through hole 15, and then the pin 12 is passed through the first mounting hole 13 and the second mounting hole 14 in sequence, thereby connecting the buckle 2 with the link 101.

[0161] In the description of this specification, specific features, structures, materials, or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0162] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claimed rights.
