Description

Technical Field

[0001] This application relates to the field of wearable device technology, and more particularly to cover plate assemblies, watch straps, and wearable devices. Background Technology

[0002] Wearable devices generally refer to miniature electronic devices that can be worn on the body for activities, including smartwatches and smart bracelets.

[0003] Taking smartwatches as an example, a smartwatch can include a strap, a watch body, and a connection structure. The strap is used to wrap around the user's wrist, the watch body is used for display, and the connection structure allows the strap length to be adjusted. Current connection structures suffer from poor strap length adjustment and are relatively heavy, gradually failing to meet users' increasingly demanding requirements for a comfortable wearing experience. Summary of the Invention

[0004] Embodiments of this application provide a cover plate assembly, a watch strap, and a wearable device. The cover plate assembly is easy to connect and detach, and has low thickness and weight, which helps to meet the increasingly demanding requirements of users for a better wearing experience.

[0005] In a first aspect, a cover plate assembly is provided. The cover plate assembly includes a first cover plate and a second cover plate; the first cover plate encloses a first receiving area with an opening facing the second cover plate; the second cover plate includes a base, a first protrusion, and a second protrusion, the first and second protrusions extending along the thickness direction of the base, both the first and second protrusions being connected to the base, and the second protrusion being disposed on one side of the first protrusion; wherein, after the first cover plate and the second cover plate are engaged, the first protrusion is magnetically connected to the first cover plate, and the second protrusion extends into the first receiving area. In this solution, the size of the first receiving area can be slightly larger than the size of the portion of the second protrusion extending into the first receiving area, so that the second protrusion can be precisely embedded into the first receiving area, which facilitates the embedding and disassembly of the second protrusion.

[0006] After the first cover plate and the second cover plate are engaged, the first protrusion and the first cover plate are magnetically connected, thus restricting the movement of the first and second cover plates along their thickness direction. After engagement, the second protrusion extends into the first receiving area, which restricts the movement of the second protrusion along its length and width directions, thereby restricting the movement of the first and second cover plates along their length and width directions. Disassembly and separation of the first and second cover plates can be achieved by controlling the movement of the first cover plate away from the second cover plate, or vice versa. Furthermore, while ensuring a good connection between the first and second cover plates, the magnetic attraction between the first protrusion and the first cover plate can be reduced, which helps to reduce the amount of magnetic material used in the first and second cover plates, thereby reducing the thickness and weight of the cover plate assembly.

[0007] When the cover plate assembly is used to connect the first and second strap bodies in the watch strap, the first strap body can be fixedly connected to the first cover plate, and the second protrusion can extend through the strap hole on the second strap body to the second receiving area. Thus, by controlling the connection between the first and second cover plates, a closed-loop connection between the first and second strap bodies can be easily achieved; by controlling the disassembly and separation of the first and second cover plates, an open-loop separation between the second strap bodies can be easily achieved, thereby enabling the wearing and detachment of the watch strap. Furthermore, by only needing to incorporate magnetic materials (such as magnetic components or materials) on the first and second cover plates, the watch strap has a lower weight and a superior feel, providing a better wearing experience for the user and meeting the increasingly demanding requirements of users.

[0008] In some examples, the second cover plate includes a base, a plurality of first protrusions and second protrusions, the first protrusions being connected to the edge of the base, and the second protrusions being disposed between the plurality of first protrusions. For example, the first protrusions are connected to the edge of the base, and the second protrusions are connected to the center of the base.

[0009] The first protrusion is connected to the edge of the base, which is equivalent to the first protrusion being located at the edge of the second cover plate. When the first cover plate and the second cover plate are engaged, the first protrusion and the first cover plate are magnetically connected. The edge of the second cover plate and the first cover plate have a good magnetic adsorption effect, which helps to restrict the movement of the first cover plate and the second cover plate along the thickness direction.

[0010] In one possible implementation, the first cover plate has a first groove with an opening facing the first protrusion in the second cover plate, and a first magnetic component (which can be a ferromagnetic material or a ferrimagnetic material, for example, a magnet) is disposed in the first groove; the first protrusion has a second groove with an opening facing the first groove, and a second magnetic component (which can be a ferromagnetic material or a ferrimagnetic material, for example) is disposed in the second groove; after the first cover plate and the second cover plate are engaged, the first magnetic component and the second magnetic component are magnetically connected.

[0011] After the first cover plate and the second cover plate are engaged, the first magnetic component and the second magnetic component attract each other, which can restrict the movement of the first cover plate and the second cover plate along the thickness direction; after the first cover plate and the second cover plate are separated, the first magnetic component and the second magnetic component no longer attract each other. In this way, it is easy to connect and separate the first cover plate and the second cover plate in the cover plate assembly.

[0012] In some examples, a plurality of first magnetic components are arrayed in the first groove, and a plurality of second magnetic components are arrayed in the second groove. After the first cover plate and the second cover plate are snapped together, the plurality of first magnetic components and the plurality of second magnetic components are magnetically connected accordingly. When the magnetic components are arranged in the same area, a single magnetic component is split into multiple magnetic components. The multiple magnetic components in the first cover plate will attract each other accordingly, and the first cover plate and the second cover plate have a better magnetic adsorption effect. While ensuring that the first cover plate and the second cover plate have a better magnetic adsorption effect, the magnetic attraction force between the first cover plate and the second cover plate can be reduced, which is beneficial to reducing the amount of magnetic material used in the first cover plate and the second cover plate, thereby reducing the thickness and weight of the cover plate assembly.

[0013] In one possible implementation, the first cover plate is provided with a third groove with an opening facing the first protrusion in the second cover plate, and a third magnetic component (the third magnetic component can be a magnetic material such as a ferromagnetic material or a ferrimagnetic material) is provided in the third groove; the first protrusion is made of a first magnetic material (the first magnetic material can be a metal, for example, the metal can be at least one of iron, cobalt or nickel); after the first cover plate and the second cover plate are fastened together, the third magnetic component and the first protrusion are magnetically connected.

[0014] After the first cover plate and the second cover plate are engaged, the third magnetic component can attract the second cover plate, thus restricting the movement of the first and second cover plates along the thickness direction. After the first and second cover plates are separated, the third magnetic component no longer attracts the second cover plate. In this way, it is easy to connect and separate the first and second cover plates in the cover plate assembly.

[0015] In some examples, multiple third magnetic components are arrayed within the third groove; after the first cover plate and the second cover plate are engaged, the multiple third magnetic components and the first protrusion are magnetically connected. This reduces the thickness and weight of the cover plate assembly, achieving a thinner and lighter design.

[0016] In one possible implementation, the first cover plate includes a first receiving portion and a first connecting portion, the first connecting portion extending along the thickness direction of the first receiving portion and connected to the edge of the first receiving portion; the first receiving portion encloses to form a first receiving area.

[0017] The first receiving portion in the first cover plate forms a first receiving area. After the first cover plate and the second cover plate are fastened together, the second protrusion in the second cover plate extends into the first receiving area formed by the first receiving portion, which can restrict the movement of the first cover plate and the second cover plate along the length and width directions.

[0018] In some examples, the first connecting portion in the first cover plate and the first protrusion in the second cover plate are magnetically connected.

[0019] The first connecting portion is connected to the edge of the first receiving portion, which is equivalent to the first connecting portion being located at the edge of the first cover plate. Similarly, the first protrusion can be connected to the edge of the base, which is equivalent to the first protrusion being located at the edge of the second cover plate. After the first and second cover plates are engaged, the first connecting portion and the first protrusion can be magnetically connected, meaning the edges of the first and second cover plates are magnetically connected. If the center of the first and second cover plates are magnetically connected, the connection between their edges may be poor. Therefore, by magnetically connecting the edges of the first and second cover plates, the connection effect is better. Furthermore, because the connection effect between the first and second cover plates is better, while ensuring a good connection between them, the magnetic attraction between the first protrusion and the first cover plate can be reduced, thus reducing the mass and thickness of the cover plate assembly and achieving a thinner and lighter cover plate assembly.

[0020] In one possible implementation, the first connecting portion includes a magnetic connection area and a constraint area, the constraint area extending along the thickness direction of the magnetic connection area and connected to the edge of the magnetic connection area; wherein, after the first cover plate and the second cover plate are engaged relative to each other, the magnetic connection area and the first protrusion are magnetically connected, and the constraint area is attached to one side of the first protrusion to restrict the movement of the first cover plate.

[0021] Since the magnetic connection area is located at the edge of the first cover plate, after the first cover plate and the second cover plate are engaged, a magnetic connection can be achieved between the edge of the first cover plate and the second cover plate, resulting in a superior magnetic connection effect. Furthermore, after the first cover plate and the second cover plate are engaged, the constraint area adheres to one side of the first protrusion, which can restrict the movement of the constraint area and the first protrusion along the width direction, thus restricting the movement of the first cover plate and the second cover plate along the width direction.

[0022] In one possible implementation, the edge of the first protrusion is provided with a protrusion, and the edge of the constraint area is provided with a recess; wherein, after the first cover plate and the second cover plate are engaged with each other, the recess of the constraint area fits into the protrusion of the first protrusion.

[0023] After the first and second cover plates are engaged, the recess in the constraint area can fit against the protrusion of the first convex part. This fit can occur not only along the thickness direction but also along the width direction, thus restricting the movement of the constraint area and the first convex part along both the width and thickness directions. In other words, it restricts the movement of the first and second cover plates along both the width and thickness directions. Furthermore, because the connection between the first and second cover plates is superior, while maintaining a good connection, the magnetic attraction between the first convex part and the first cover plate can be reduced, decreasing the mass and thickness of the cover plate assembly and achieving a thinner and lighter design.

[0024] In one possible implementation, the cover plate assembly further includes a first limiting member, which comprises a second connecting portion and a second receiving portion. The second receiving portion is disposed on the side of the second connecting portion facing the first receiving area, and the second receiving portion surrounds and forms a second receiving area. The second connecting portion and the first protrusion are magnetically connected, and the second receiving portion can be accommodated within the first receiving area. After the first cover plate and the second cover plate are engaged, the second protrusion extends into the second receiving area. In this solution, the size of the first receiving area can be slightly larger than the size of the portion of the second receiving portion extending into the first receiving area, so that the second receiving portion can be precisely embedded in the first receiving area, facilitating the embedding and separation of the second receiving portion. Furthermore, the internal size of the second receiving area can be slightly larger than the external size of the second protrusion, so that the second receiving portion is precisely embedded in the second receiving area, facilitating the embedding and separation of the second protrusion.

[0025] After the first cover plate and the second cover plate are engaged, the second protrusion extends into the second receiving area formed by the second receiving portion. The second receiving area can restrict the movement of the second protrusion, thereby restricting the movement of the first cover plate and the second cover plate along the length and width directions.

[0026] In one possible implementation, the second connecting portion and the first protrusion are rotatably connected; after the first limiting member is engaged with the first cover plate, the second connecting portion and the first protrusion are magnetically connected. In some examples, the rotatable connection between the second connecting portion and the first cover plate can be a hinge connection or a bearing connection.

[0027] Since the second connecting part and the first protrusion are rotatably connected, the relative position between the first limiting member and the first cover plate can be changed by rotating the second connecting part or the first protrusion. The second protrusion and the second receiving area of ​​the second cover plate can be separated, which is beneficial to the separation of the first cover plate and the second cover plate.

[0028] Secondly, another cover plate assembly is provided. This cover plate assembly includes: a first cover plate, a second cover plate, and a second limiting member. The second cover plate is disposed between the first cover plate and the second limiting member. After the first cover plate and the second cover plate are engaged, they are magnetically connected. The second limiting member includes a limiting portion and a rotating portion, which are rotatably connected to the second cover plate. A clamping space is formed between the rotating portion and the second cover plate, which can be used to clamp the structure to be connected. In some examples, the rotatable connection between the limiting portion and the second cover plate can be a pivot connection or a hinge connection.

[0029] After the first cover plate and the second cover plate are engaged, they are magnetically connected, making it easy to connect and disassemble the first cover plate and the second cover plate. The second limiting member and the second cover plate are rotatably connected, forming a clamping space between the second limiting member and the second cover plate. The clamping space can be used to clamp the structure to be connected. By rotating the second limiting member, the target position of the second limiting member clamping the structure to be connected can be adjusted, thereby adjusting the size of the structure to be connected according to the user's needs.

[0030] When the cover plate assembly is used to connect the first and second strap bodies in the watch strap, the first strap body can be fixedly connected to the first cover plate, and the second strap body can be positioned in the clamping space formed between the second limiting member and the second cover plate. By rotating the second limiting member, the position of the second strap body clamped by the second limiting member can be adjusted, thereby adjusting the size of the second strap body according to user needs. This facilitates closed-loop connection and open-loop separation of the first and second strap bodies, enabling the wearing and detachment of the watch strap. Furthermore, by simply incorporating magnetic materials (such as magnetic components or materials) on the first and second cover plates, the watch strap exhibits lower weight and superior texture, providing a better wearing experience and meeting the increasingly demanding requirements of users.

[0031] In one possible implementation, the first cover plate has a fourth groove with an opening facing the second cover plate, and a fourth magnetic component (which can be a ferromagnetic material or a ferrimagnetic material, etc.) is disposed within the fourth groove; the second cover plate has a fifth groove with an opening facing the fourth groove, and a fifth magnetic component (which can be a ferromagnetic material or a ferrimagnetic material, etc.) is disposed within the fifth groove; after the first cover plate and the second cover plate are engaged, the fourth groove is accommodated within the fifth groove (in this scheme, the inner dimension of the fifth groove can be slightly larger than the outer dimension of the fourth groove so that the fourth groove is just accommodated within the fifth groove), or the fifth groove is accommodated within the fourth groove (in this scheme, the inner dimension of the fifth groove can be slightly larger than the outer dimension of the fourth groove so that the fifth groove is just accommodated within the fourth groove); and the fourth magnetic component and the fifth magnetic component are magnetically connected.

[0032] The fourth and fifth magnetic components attract each other, and the first and second cover plates have a good magnetic connection effect, which helps to restrict the movement of the first and second cover plates in the thickness direction. In addition, after the first and second cover plates are engaged, the fourth groove is accommodated in the fifth groove, or the fifth groove is accommodated in the fourth groove, which helps to restrict the movement of the first and second cover plates in the length and width directions.

[0033] In some examples, a plurality of fourth magnetic components are arranged in an array in the fourth groove, and a plurality of fifth magnetic components are arranged in an array in the fifth groove; after the first cover plate and the second cover plate are fastened together, the plurality of fourth magnetic components and the plurality of fifth magnetic components are magnetically connected accordingly.

[0034] When the magnetic components are in the same location, a single magnetic component is split into multiple magnetic components. The multiple fourth magnetic components in the fourth groove will attract each other with the multiple fifth magnetic components in the fifth groove. The first cover plate and the second cover plate have better magnetic adsorption effect. While ensuring that the first cover plate and the first limiting member have a good connection effect, the magnetic attraction between the first cover plate and the second cover plate can be reduced, the mass and thickness of the cover plate assembly can be reduced, and the cover plate assembly can be made thinner and lighter.

[0035] In one possible implementation, the first cover plate has a sixth groove with an opening facing the second cover plate, and a sixth magnetic component (which can be a ferromagnetic material or a ferrimagnetic material, etc.) is disposed in the sixth groove; the second cover plate has a third protrusion facing the sixth groove, and the third protrusion is made of a second magnetic material (which can be a metal); after the first cover plate and the second cover plate are engaged, the third protrusion is accommodated in the sixth groove (the inner dimension of the sixth groove can be slightly larger than the outer dimension of the third protrusion so that the third protrusion is just accommodated in the sixth groove); the sixth magnetic component and the third protrusion are magnetically connected.

[0036] The sixth magnetic component can attract the third protrusion. The first cover plate and the second cover plate have a good magnetic connection effect, which helps to restrict the movement of the first cover plate and the second cover plate in the thickness direction. In addition, after the first cover plate and the second cover plate are engaged, the third protrusion is accommodated in the sixth groove, which helps to restrict the movement of the first cover plate and the second cover plate in the length direction and the width direction.

[0037] In some examples, a plurality of sixth magnetic components are arranged in an array within the sixth groove; after the first cover plate and the second cover plate are engaged, the plurality of sixth magnetic components and the third protrusion are magnetically connected.

[0038] Thirdly, a watch strap is provided, comprising: a first strap body, a second strap body, and a cover plate assembly in any possible implementation of the first aspect, wherein the second strap body is provided with a plurality of strap holes; wherein the first strap body and the first cover plate are fixedly connected, and the fixed connection between the first strap body and the first cover plate includes one of hinge connection, welding connection, screw connection, and snap-fit ​​connection; after the first cover plate and the second cover plate are fastened together, a second protrusion extends through the strap holes into a first receiving area.

[0039] In one possible implementation, the second strip is made of a rigid material. For example, the material of the second strip may include adhesive or plastic materials.

[0040] Fourthly, another watch strap is provided, the watch strap comprising: a first strap body, a second strap body, and a cover plate assembly of any possible implementation of the second aspect; the first strap body and the first cover plate are fixedly connected, and the second strap body is disposed in a clamping space formed between the rotating part and the second cover plate.

[0041] In one possible implementation, the thickness of the second belt is L1, the dimension of the limiting part of the first limiting member and the second cover plate along the thickness direction is L2, and the ratio of L1 to L2 is 1:(0.5-0.7).

[0042] In one possible implementation, the second belt may be made of a flexible material. For example, the second belt may be made of a woven material, such as nylon or canvas.

[0043] Fifthly, a wearable device is provided, the wearable device including a watch body; and a watch strap according to any possible implementation of the third aspect, or a watch strap according to any possible implementation of the fourth aspect; wherein one end of the watch body is connected to a first strap body in the watch strap, and the other end of the watch body is connected to a second strap body in the watch strap.

[0044] The technical effects of any of the possible implementations of the third, fourth, and fifth aspects can be found in the technical effects of different implementations of the first or second aspects described above, and will not be repeated here. Attached Figure Description

[0074] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. Hereinafter, the terms "first," "second," etc., are used only for descriptive purposes to distinguish identical or similar items with substantially the same function and effect, and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0075] This application provides a wearable device, which can be a smart bracelet or a smartwatch. The wearable device can be worn on the wrist to perform functions such as time display, timekeeping, time announcement, message notification, activity detection, heart rate monitoring, and blood oxygen level detection. The wearable device may include a strap and a body; the strap is used to wrap around the user's wrist for wearing, and the body is used to display information.

[0076] In this embodiment of the application, a smartwatch is used as an example of a wearable device for illustration. Figure 1 This is a schematic diagram of the structure of a wearable device provided in an embodiment of this application; Figure 2 This is a schematic diagram of the structure of a watch strap; Figure 3 This is a schematic diagram of another type of watch strap.

[0077] See Figure 1The wearable device includes a watch body 1, a first watch band 2, and a second watch band 3. The watch body 1 is connected between the first watch band 2 and the second watch band 3. The watch body 1, the first watch band 2, and the second watch band 3 can form a closed loop to wrap around the wrist. The watch body 1 can be round, rectangular, or other shapes.

[0078] The device body 1 may include a housing and a display screen, which together form an accommodating space. Exemplarily, the accommodating space can be used to accommodate various functional modules and electronic components of the wearable device, including but not limited to: a processor, internal memory, a universal serial bus (USB) interface, a charging management module, a power management module, a battery, an antenna, a mobile communication module, a wireless communication module, an audio module, a speaker, a microphone, a sensor module, buttons, a motor, an indicator, a camera, and a subscriber identification module (SIM) card interface, etc.

[0079] The watch strap can be detachably connected to the watch body 1. For example, see Figure 2 The two watch straps are detachably connected to the watch body 1, for example, see Figure 3 Each watch strap is detachably connected to the watch body 1.

[0080] For example, see Figure 1 and Figure 2The watch body 1 is connected between the first watch band 2 and the second watch band 3. The first watch band 2 includes a first watch band base material 2-1, a first magnet 2-2, and a first connecting structure 2-3 (e.g., a buckle structure). Multiple first magnets 2-2 are evenly arranged on the first watch band base material 2-1, and the first connecting structure 2-3 is located at the end of the first watch band base material 2-1. One end of the watch body 1 and the first watch band 2 are connected through the first connecting structure 2-3. The second watch band 3 includes a second watch band base material 3-1, a second magnet 3-2, and a second connecting structure 3-3 (e.g., a buckle structure). Multiple second magnets 3-2 are evenly arranged on the second watch band base material 3-1, and the second connecting structure 3-3 is located at the end of the second watch band base material 3-1. The other end of the watch body 1 and the second watch band 3 are connected through the second connecting structure 3-3. When the wearable device needs to be wrapped around the user's wrist, the first magnet 2-2 on the first watch band 2 will magnetically attract the second magnet 3-2 on the second watch band 3, thereby realizing the adjustment of the wrist circumference of the user wearing the wearable device. The problems with this solution include: (1) The first watchband 2 and the second watchband 3 are equipped with multiple magnets, making the first watchband 2 and the second watchband 3 heavy, resulting in a heavy wearable device and a poor user experience; (2) The first watchband 2 and the second watchband 3 are evenly equipped with multiple magnets, which will come into contact with the user's wrist, resulting in a poor texture of the first watchband 2 and the second watchband 3 and a poor user experience; (3) The connection effect of the first watchband 2 and the second watchband 3 is poor, and the first watchband 2 and the second watchband 3 are prone to separation during the user's wearing process.

[0081] For another example, see Figure 1 and Figure 3The first watchband 2 includes a first watchband base material 2-1, a first magnet 2-2, and a first connecting structure 2-3 (e.g., a buckle structure). The first magnet 2-2 is disposed at one end of the first watchband base material 2-1. One end of the watch body 1 and the other end of the first watchband base material 2-1 are connected by the first connecting structure 2-3. The other end of the watch body 1 and the middle part of the first watchband base material 2-1 are connected by the first connecting structure 2-3. Metal is disposed on the first watchband base material 2-1 (e.g., metal is uniformly disposed on the first watchband base material 2-1 along its length). The first magnet 2-2 can magnetically attract the metal on the first watchband base material 2-1. When the watchband needs to be wrapped around the user's wrist, the position of the first magnet 2-2 can be adjusted. The first magnet 2-2 magnetically attracts the metal at different positions on the first watchband base material 2-1, thereby enabling the user to adjust the wrist circumference when wearing the wearable device. The problems with this solution include: (1) The first watchband 2 and the second watchband 3 are made of metal, and the first watchband 2 and the second watchband 3 are relatively heavy, resulting in a heavy wearable device and a poor user experience when wearing the wearable device; (2) The first watchband 2 and the second watchband 3 are evenly made of metal, and the metal will come into contact with the user's wrist, resulting in a poor texture of the first watchband 2 and the second watchband 3 and a poor user experience when wearing the wearable device; (3) The connection effect of the first watchband 2 and the second watchband 3 is poor, and the first watchband 2 and the second watchband 3 are prone to separation during the user's wearing process.

[0082] Based on this, embodiments of this application provide a cover plate assembly that is easy to connect and disassemble, and has low thickness and weight, which is beneficial to meeting the increasingly demanding user experience. When the cover plate assembly is used to connect a watch strap, it facilitates closed-loop connection and open-loop separation of the watch strap, resulting in a watch strap with lower weight and better texture. Users who wear this watch strap experience a superior wearing experience, which is beneficial to meeting the increasingly demanding requirements of users.

[0084] Figure 4 This is a perspective structural diagram of a cover plate assembly provided in an embodiment of this application. Figure 5 This is a three-dimensional structural diagram of a watch strap provided in an embodiment of this application. Figure 5 The watch strap shown is Figure 4 A structure in which the cover plate assembly connects the first belt body 10 and the second belt body 30. Figure 4 The cover plate assembly shown can also achieve the connection between the first belt body 10 and the second belt body 30 in other ways.

[0085] This embodiment provides a cover plate assembly, see [link / reference] Figure 4 and Figure 6 The cover plate assembly includes a first cover plate 210 and a second cover plate 220. The first cover plate 210 surrounds a first receiving area with an opening facing the second cover plate 220. The second cover plate 220 includes a base 2210, a first protrusion 2220 and a second protrusion 2230. The first protrusion 2220 and the second protrusion 2230 extend along the thickness direction of the base 2210. The first protrusion 2220 and the second protrusion 2230 are both connected to the base 2210, and the second protrusion 2230 is disposed on one side of the first protrusion 2220. After the first cover plate 210 and the second cover plate 220 are engaged, the first protrusion 2220 is magnetically connected to the first cover plate 210, and the second protrusion 2230 extends into the first receiving area. In this design, the size of the first receiving area can be slightly larger than the size of the portion of the second protrusion 2230 extending into the first receiving area, so that the second protrusion 2230 can be precisely embedded into the first receiving area. This facilitates the embedding and disassembly of the second protrusion 2230. For example, along the width and thickness directions, the size of the first receiving area can be slightly larger than the size of the portion of the second protrusion 2230 extending into the first receiving area; along the thickness direction, the size of the first receiving area is larger than the size of the portion of the second protrusion 2230 extending into the first receiving area. The embodiments in this application are not limited in scope.

[0086] After the first cover plate 210 and the second cover plate 220 are engaged, the first protrusion 2220 and the first cover plate 210 are magnetically connected, which restricts the movement of the first cover plate 210 and the second cover plate 220 along the thickness direction. After the first cover plate 210 and the second cover plate 220 are engaged, the second protrusion 2230 extends into the first receiving area, which restricts the movement of the second protrusion 2230 along the length and width directions, that is, it restricts the movement of the first cover plate 210 and the second cover plate 220 along the length and width directions. This achieves the connection between the first cover plate 210 and the second cover plate 220. By controlling the first cover plate 210 to move away from the second cover plate 220, or by controlling the second cover plate 220 to move away from the first cover plate 210, the first cover plate 210 and the second cover plate 220 can be disassembled and separated. Furthermore, since the first receiving area can restrict the movement of the second protrusion 2230 along the length and width directions, while ensuring a good connection between the first cover plate 210 and the second cover plate 220, the magnetic attraction between the first protrusion 2220 and the first cover plate 210 is low, the amount of magnetic material (such as magnetic components or magnetic materials) used in the cover plate assembly is small, and the mass of the cover plate assembly is low.

[0087] In some embodiments, when the cover plate assembly is used to connect the first strap body 10 and the second strap body 30 in the watch strap, see [reference needed]. Figure 5 and Figure 6 The watch strap includes a first strap body 10, a second strap body 30, and a cover plate assembly. The second strap body 30 has multiple strap holes 310. The first strap body 10 can be fixedly connected to the first cover plate 210. After the first cover plate 210 and the second cover plate 220 are fastened together, on the one hand, the first cover plate 210 and the second cover plate 220 will be magnetically connected, restricting the movement of the first cover plate 210 and the second cover plate 220 along the thickness direction. On the other hand, the second protrusion on the second cover plate 220 can extend through the strap holes 310 on the second strap body 30 to the first receiving area, which can restrict the movement of the first cover plate 210 and the second cover plate 220 along the length direction and the width direction. By controlling the connection of the first cover plate 210 and the second cover plate 220 in the cover plate assembly, a closed-loop connection between the first strap body 10 and the second strap body 30 can be easily achieved. By controlling the disassembly and separation of the first cover plate 210 and the second cover plate 220, an open-loop separation between the second strap body 30 and the second strap body 30 can be easily achieved, thereby realizing the wearing and detachment of the watch strap. Furthermore, only magnetic materials (such as magnetic components or magnetic materials) need to be provided on the first cover plate 210 and the second cover plate 220, instead of uniformly providing magnets or metals on the first strap body 10 and the second strap body 30. The strap has a lower weight and a better texture, and the user has a better wearing experience, which helps to meet the increasingly higher requirements of users.

[0088] In other embodiments, the second cover plate 220 in the cover plate assembly does not have a first receiving area. Instead, it relies solely on the magnetic connection between the first cover plate 210 and the second cover plate 220 to suppress movement of the first cover plate 210 and the second cover plate 220 along the thickness, length, and width directions. This approach easily leads to the first cover plate 210 and the second cover plate 220 detaching. When the cover plate assembly is used to connect the first strap body 10 and the second strap body 30 of the watch strap, the first strap body 10 and the second strap body 30 are prone to separation during wear, potentially causing discomfort to the user. The wearing experience is poor. In order to solve the problem that the first cover plate 210 and the second cover plate 220 are easy to separate, it is usually necessary to increase the magnetic attraction between the first cover plate 210 and the second cover plate 220. This will result in a large mass and thickness of the magnetic material (such as magnetic components or magnetic materials) in the first cover plate 210 and the second cover plate 220, making it difficult to achieve a thinner cover plate assembly and watch strap. It will also result in an excessive magnetic attraction between the first cover plate 210 and the second cover plate 220, making it difficult to separate the first cover plate 210 and the second cover plate 220, resulting in a poor user experience.

[0089] In some possible implementations, the second belt 30 can be made of a rigid material, which may include adhesive materials and plastic materials. For example, adhesive materials include rubber, silicone, and thermoplastic polyurethane. Thus, when the second belt 30 is made of an adhesive material, the second belt 30 has high elasticity. See [link to relevant documentation]. Figure 5By setting the end size of the first protrusion 2220 to be relatively large, the first protrusion 2220 with a larger end size will undergo compression deformation when passing through the strap hole 310, and will expand and recover when entering the first receiving area. This can further restrict the movement of the second cover plate 220 along the length, width, and thickness directions. In some possible embodiments, the material of the first strap 10 can be a rigid material or a flexible material. For example, the rigid material can be a rubber material, and the flexible material can be a woven material. Of course, the first strap 10 can also be made of other materials, and this application embodiment does not constitute a limitation.

[0090] In some embodiments, see Figure 6 The second cover plate 220 includes a base 2210, a plurality of first protrusions 2220 and a second protrusion 2230. The plurality of first protrusions 2220 are connected to the edge of the base 2210, and the second protrusions 2230 are disposed between the plurality of first protrusions 2220. For example, the first protrusions 2220 are connected to the edge of the base 2210, and the second protrusions 2230 are connected to the center of the base 2210.

[0091] The first protrusion 2220 is connected to the edge of the base 2210, which means the first protrusion 2220 is located at the edge of the second cover plate 220. When the first cover plate 210 and the second cover plate 220 are engaged, the first protrusion 2220 and the first cover plate 210 are magnetically connected. The edge of the second cover plate 220 and the first cover plate 210 have a good magnetic adsorption effect, which helps to restrict the movement of the first cover plate 210 and the second cover plate 220 along the thickness direction. If the center of the first cover plate 210 and the center of the second cover plate 220 are magnetically connected, it may cause the edge of the first cover plate 210 and the second cover plate 220 to move. The connection effect at the edge of the cover plate 220 is poor. Therefore, by magnetically connecting the edge of the first cover plate 210 and the second cover plate 220, the connection effect of the first cover plate 210 and the second cover plate 220 is better. The second protrusion 2230 is disposed between the multiple first protrusions 2220. When the first cover plate 210 and the second cover plate 220 are engaged, the second protrusion 2230 will extend into the first receiving area formed by the first cover plate 210. The first receiving area will restrict the movement of the second protrusion 2230, thereby restricting the movement of the first cover plate 210 and the second cover plate 220 in the length and width directions.

[0092] When the cover plate assembly is used to connect the first and second strap bodies in the watch strap, see [reference needed]. Figure 6Because the edge of the second cover plate 220 in the cover plate assembly has a better connection with the first cover plate 210, the first and second strap bodies are less likely to detach during the user's wearing of the watch strap, thus improving the user's wearing experience. Furthermore, while ensuring a good connection between the first and second cover plates 210 and 220, the amount of magnetic material used in the first and second cover plates 210 and 220 can be reduced, which is beneficial for achieving a thinner watch strap. Also, because the magnetic attraction between the first and second cover plates 210 and 220 is weaker, it is easier to separate the first and second strap bodies, making it easier to detach the watch strap.

[0093] See also some possible implementations. Figure 6 The second cover plate 220 is provided with pairs of first protrusions 2220, which are symmetrically connected to the edge positions of the base 2210. For example, the number of first protrusions 2220 is even. For instance, there may be two or four first protrusions 2220, etc., and this embodiment does not impose any special limitation on this. In some other possible implementations, the first protrusions 2220 in the second cover plate 220 are not arranged in pairs, and the number of first protrusions 2220 connected to one edge position of the base 2210 is greater than the number of first protrusions 2220 connected to the other edge position of the base 2210. The number of first protrusions 2220 can be even or odd. For example, if the number of first protrusions 2220 connected to one edge of the base 2210 is 1, and the number of first protrusions 2220 connected to the other edge of the base 2210 is 3, then the number of first protrusions 2220 is even; as another example, if the number of first protrusions 2220 connected to one edge of the base 2210 is 1, and the number of first protrusions 2220 connected to the other edge of the base 2210 is 2, then the number of first protrusions 2220 is odd.

Among them, Figure 5 The watch strap shown and Figure 8 The watch straps shown are the same, and the settings are the same. Figure 5 and Figure 8 This is to more clearly show the location of different cross-sections.

[0095] In some embodiments, see Figure 7 , Figure 12 and Figure 13 The first cover plate 210 includes a first receiving portion 2110 and a first connecting portion 2120. The first connecting portion 2120 extends along the thickness direction of the first receiving portion 2110 and is connected to the edge of the first receiving portion 2110. The first connecting portion 2120 can be magnetically connected to the first protrusion 2220. The first receiving portion 2110 surrounds and forms a first receiving area.

[0096] On one hand, the first connecting portion 2120 is connected to the edge of the first receiving portion 2110, that is, the first connecting portion 2120 is disposed at the edge of the first cover plate 210, and the first protrusion 2220 can also be connected to the edge of the base portion 2210, that is, the first protrusion 2220 can also be disposed at the edge of the second cover plate 220. After the first cover plate 210 and the second cover plate 220 are engaged, the first connecting portion 2120 can be magnetically connected to the first protrusion 2220, thereby realizing the magnetic connection between the edge of the first cover plate 210 and the edge of the second cover plate 220. Compared with the magnetic connection between the center of the first cover plate 210 and the center of the second cover plate 220, the edge of the first cover plate 210 and the edge of the second cover plate 220 may be affected. In cases where the magnetic connection effect is poor, the edges of the first cover plate 210 and the second cover plate 220 are magnetically connected. The first cover plate 210 and the second cover plate 220 have a better magnetic adsorption effect, which can restrict the movement of the first cover plate 210 and the second cover plate 220 along the thickness direction (Z direction). On the other hand, the first receiving portion 2110 in the first cover plate 210 forms a first receiving area. After the first cover plate 210 and the second cover plate 220 are fastened together, the second protrusion 2230 in the second cover plate 220 will extend through the watch strap hole 310 on the second strap body 30 into the first receiving area formed by the first receiving portion 2110, thus restricting the movement of the first cover plate 210 and the second cover plate 220 along the length direction (Y direction) and the width direction (X direction).

[0097] When the cover plate assembly is used to connect the first and second strap bodies in the watch strap, see [reference needed]. Figure 7 , Figure 12 and Figure 13Because the connection between the edges of the second cover plate 220 and the first cover plate 210 is superior, the first and second strap bodies are less likely to detach during wear, improving the user's experience. Furthermore, while ensuring a good connection between the first and second strap bodies, the amount of magnetic material used in the first and second cover plates 210 and 220 can be reduced, facilitating a thinner strap. Additionally, the weaker magnetic attraction between the first and second cover plates 210 and 220 makes it easier to separate the first and second strap bodies, allowing for easier disassembly of the strap.

[0098] In some embodiments, see Figure 11 and Figure 13 The first connecting portion 2120 includes a magnetic connection area 2121 and a constraint area 2122. The constraint area 2122 extends along the thickness direction of the magnetic connection area 2121 and is connected to the edge of the magnetic connection area 2121. After the first cover plate 210 and the second cover plate 220 are engaged, the magnetic connection area 2121 and the first protrusion 2220 are magnetically connected, and the constraint area 2122 is attached to one side of the first protrusion 2220 to restrict the movement of the first cover plate 210. In some possible embodiments, the structure of the constraint area 2122 near the first protrusion 2220 can be configured according to the area to be bonded between the constraint area 2122 and the first protrusion 2220.

[0099] Since the magnetic connection area is located at the edge of the first cover plate 210, after the first cover plate 210 and the second cover plate 220 are engaged, a magnetic connection can be achieved between the edge of the first cover plate 210 and the second cover plate 220, resulting in a superior magnetic connection effect. Furthermore, after the first cover plate 210 and the second cover plate 220 are engaged, the constraint area 2122 adheres to one side of the first protrusion 2220, which can restrict the movement of the constraint area 2122 and the first protrusion 2220 along the width direction, thus restricting the movement of the first cover plate 210 and the second cover plate 220 along the width direction.

[0100] When the cover plate assembly is used to connect the first band body 10 and the second band body 30 in the watch strap, by setting a constraint area 2122 at the first connecting part of the first cover plate 210, the movement of the first cover plate 210 and the second cover plate 220 in the width direction can be restricted. During the process of the user wearing the watch strap, the first band body 10 and the second band body 30 are less likely to detach, which can improve the user's experience of wearing the watch strap.

[0101] In some embodiments, see Figure 11 and Figure 13The first protrusion 2220 has a protrusion at its edge, and the constraint area 2122 has a recess at its edge; wherein, after the first cover plate 210 and the second cover plate 220 are engaged, the recess of the constraint area 2122 fits against the protrusion of the first protrusion 2220. In the embodiments of this application, the structure of the protrusion and the shape of the recess are not particularly limited; for example, the protrusion can be... Figure 11 The edge structure in the middle is a recessed structure corresponding to the edge structure, and the protrusion can also be an arc-shaped structure, with the recessed structure being an arc-shaped depression corresponding to the arc-shaped structure.

[0102] After the first cover plate 210 and the second cover plate 220 are engaged, the recess of the constraint area 2122 can fit into the protrusion of the first protrusion 2220. The recess of the constraint area 2122 and the protrusion of the first protrusion 2220 can fit together not only along the thickness direction but also along the width direction, thereby restricting the movement of the constraint area 2122 and the first protrusion 2220 along the width direction and the thickness direction, that is, restricting the movement of the first cover plate 210 and the second cover plate 220 along the width direction and the thickness direction.

[0103] The magnetic connection method between the first cover plate 210 and the second cover plate 220 is explained below. Of course, the first cover plate 210 and the second cover plate 220 may also include other magnetic connection methods. The following embodiments do not limit the magnetic connection between the first cover plate 210 and the second cover plate 220.

[0104] In some embodiments, see Figure 7 The first cover plate 210 is provided with a groove for a first protrusion 2220 with an opening facing the second cover plate 220. A magnetic component is provided in the groove of the first cover plate 210. The first protrusion 2220 is provided with a groove with an opening facing the first cover plate 210. A magnetic component is provided in the groove of the first protrusion 2220. After the first cover plate 210 and the second cover plate 220 are fastened together, the magnetic component in the first cover plate 210 and the magnetic component in the first protrusion 2220 will be magnetically connected. In this way, after the first cover plate 210 and the second cover plate 220 are engaged, the magnetic components in the first cover plate 210 and the magnetic components in the first protrusion 2220 attract each other, and the magnetic connection between the first cover plate 210 and the second cover plate 220 is better, which can restrict the movement of the first cover plate 210 and the second cover plate 220 along the thickness direction; after the first cover plate 210 and the second cover plate 220 are separated, the magnetic components in the first cover plate 210 and the magnetic components in the first protrusion 2220 no longer attract each other.

[0105] When the cover plate assembly is used to connect the first strap body 10 and the second strap body 30, the first cover plate 210 and the second cover plate 220 are magnetically connected, achieving a closed-loop connection between the first strap body 10 and the second strap body 30. At this time, the watch strap is worn on the user's wrist. After the first cover plate 210 and the second cover plate 220 are separated, the magnetic components in the first cover plate 210 and the second cover plate 220 no longer attract each other, and the first cover plate 210 and the second cover plate 220 are no longer magnetically connected. At this time, the watch strap is detached from the user's wrist. In addition, placing the magnetic components in the grooves of the first cover plate 210 and the second cover plate 220 can prevent the magnetic components from being directly exposed to the outside, which helps to improve the aesthetics of the watch strap.

[0106] In some examples, the number of grooves in the first cover plate 210 can be multiple. In some examples, the number of grooves in the first protrusion 2220 of the second cover plate 220 can be multiple. In some examples, a magnetic suction cup is provided on the side of the magnetic component in the groove of the first cover plate 210 near the groove of the first protrusion 2220. This avoids direct exposure of the magnetic component in the groove of the first cover plate 210, which helps protect the magnetic component and improves the aesthetics of the watch strap. In some examples, a magnetic suction cup is provided on the side of the magnetic component in the groove of the first protrusion 2220 near the groove of the first cover plate 210. This avoids direct exposure of the magnetic component in the groove of the first protrusion 2220, which helps protect the magnetic component and improves the aesthetics of the watch strap.

[0107] For example, see Figure 7 , Figure 8 , Figure 11 The magnetic contact area 2121 of the first connecting portion 2120 of the first cover plate 210 is provided with two grooves with openings facing the second cover plate 220. A magnetic component 2121a and a magnetic chuck 2121b are disposed in one groove, and a magnetic component 2121c and a magnetic chuck 2121d are disposed in the other groove. The first protrusion 2220 of the second cover plate 220 is provided with two grooves with openings facing the two grooves. A magnetic component 2220a and a magnetic chuck 2220b are disposed in one groove, and a magnetic component 2220c and a magnetic chuck 2220d are disposed in the other groove. After the first cover plate 210 and the second cover plate 220 are engaged, the magnetic components 2121a and 2220a attract each other, and the magnetic components 2121c and 2220c attract each other, thereby achieving a magnetic connection between the first cover plate 210 and the second cover plate 220.

[0108] In some embodiments, the first cover plate 210 has a groove with an opening facing the second cover plate 220, and a magnetic component is disposed within the groove of the first cover plate 210; the first protrusion 2220 is made of a magnetic material; after the first cover plate 210 and the second cover plate 220 are engaged, the magnetic component in the groove of the first cover plate 210 will attract the first protrusion 2220. In some examples, the first cover plate 210 may have multiple grooves. In some examples, a magnetic chuck is disposed on the side of the magnetic component in the groove of the first cover plate 210 near the first protrusion 2220. In this embodiment, the magnetic material used for the first protrusion 2220 may be a metal, for example, the metal may be at least one of iron, cobalt, or nickel.

[0109] For example, see Figure 14 The magnetic contact area 2121 of the first connecting part 2120 of the first cover plate 210 is provided with two grooves with openings facing the second cover plate 220. One groove is provided with a magnetic component 2121a and a magnetic chuck 2121b, and the other groove is provided with a magnetic component 2121c and a magnetic chuck 2121d. The first protrusion 2220 of the second cover plate 220 is made of magnetic material. After the first cover plate 210 and the second cover plate 220 are fastened together, the magnetic components 2121a and 2121c will respectively attract the second cover plate 220 to achieve magnetic connection between the first cover plate 210 and the second cover plate 220.

[0110] In some other embodiments, see Figure 15 The magnetic contact area 2121 of the first connecting portion 2120 of the first cover plate 210 is made of a magnetic material. The first protrusion 2220 of the second cover plate 220 is provided with two grooves with openings facing the first cover plate 210. One groove contains a magnetic component 2220a and a magnetic chuck 2220b, and the other groove contains a magnetic component 2220c and a magnetic chuck 2220d. After the first cover plate 210 and the second cover plate 220 are engaged, the magnetic components 2220a and 2220c will attract the first cover plate 210, thereby achieving a magnetic connection between the first cover plate 210 and the second cover plate 220. In this design, the magnetic contact area 2121 can be made of a metal, for example, at least one of iron, cobalt, or nickel.

[0111] In some embodiments, see Figure 16The magnetic contact area 2121 of the first connecting portion 2120 of the first cover plate 210 is provided with two grooves opening towards the second cover plate 220. One groove contains sub-magnetic components 21211a, 21212a, 21213a, and a magnetic chuck 2121b arranged along the length direction (Y direction). The other groove contains sub-magnetic components 21211c, 21212c, 21213c, and a magnetic chuck 2121d arranged along the length direction. The first protrusion 2220 of the second cover plate 220 is provided with two grooves opening towards the two grooves mentioned above. One groove contains sub-magnetic components 2221a, 21212a, 21213a, and a magnetic chuck 2121d arranged along the length direction. 22a, sub-magnetic component 2223a, and magnetic chuck 2220b; another groove contains sub-magnetic components 2221c, 2222c, 2223c, and magnetic chuck 2220d arranged along the length direction; sub-magnetic components 21211a and 2221a attract each other; sub-magnetic components 21212a and 2222a attract each other; sub-magnetic components 21213a and 2223a attract each other; sub-magnetic components 21211c and 2221c attract each other; sub-magnetic components 21212c and 2222c attract each other; sub-magnetic components 21213c and 2223c attract each other. Of course, this solution can be applied to… Figure 14 , Figure 15 The magnetic connection scheme between the first cover plate 210 and the second cover plate 220 shown, in other words, will... Figure 14 , Figure 15 The single magnetic component in the first cover plate 210 is split into multiple sub-magnetic components, and the single magnetic component in the second cover plate 220 is split into multiple sub-magnetic components.

[0112] When the magnetic components are located in the same area, a single magnetic component can be divided into multiple sub-magnetic components. The multiple sub-magnetic components in the first cover plate 210 will attract each other accordingly, which can greatly improve the magnetic connection effect of the first cover plate 210 and the second cover plate 220, significantly reduce the thickness of the watch strap, achieve a thinner watch strap, and thus improve the wearing experience of the watch strap.

[0113] In some embodiments, magnetic component 2121a, magnetic component 2121c, magnetic component 2220a, magnetic component 2220c, sub-magnetic component 21211a, sub-magnetic component 21212a, sub-magnetic component 21213a, sub-magnetic component 2221a, sub-magnetic component 2222a, sub-magnetic component 2223a, sub-magnetic component 21211c, sub-magnetic component 21212c, sub-magnetic component 21213c, sub-magnetic component 2221c, sub-magnetic component 2222c, and sub-magnetic component 2223c each independently include at least one of ferromagnetic material or ferrimagnetic material. For example, the ferromagnetic material may be a magnet.

[0114] In one possible implementation, see Figure 7 , Figure 10 and Figure 12 The cover plate assembly also includes a first limiting member 230, which includes a second connecting portion 2310 and a second receiving portion 2320. The second receiving portion 2320 is disposed on the side of the second connecting portion 2310 facing the first receiving area, and the second receiving portion 2320 surrounds and forms a second receiving area. The second connecting portion 2310 and the first protrusion 2220 are magnetically connected, and the second receiving portion 2320 is received within the first receiving area. After the first cover plate 210 and the second cover plate 220 are engaged, the second protrusion 2230 extends into the second receiving area. In this design, the size of the first receiving area can be slightly larger than the size of the portion of the second receiving portion 2320 extending into the first receiving area, so that the second receiving portion 2320 can be precisely embedded in the first receiving area, facilitating the embedding and separation of the second receiving portion 2320. Furthermore, the internal size of the second receiving area can be slightly larger than the external size of the second protrusion 2230, so that the second receiving portion 2320 can be precisely embedded into the second receiving area, facilitating the embedding and separation of the second protrusion 2230. For example, along the width and thickness directions, the size of the second receiving area may be slightly larger than the size of the portion of the second protrusion 2230 extending into the second receiving area; along the thickness direction, the size of the second receiving area is larger than the size of the portion of the second protrusion 2230 extending into the second receiving area. The comparison of the embodiments in this application is not limited.

[0115] With the second connecting portion 2310 of the first limiting member 230 connected to the first cover plate 210, the second receiving portion 2320 can be accommodated in the first receiving area. After the first cover plate 210 and the second cover plate 220 are engaged, the second protrusion 2230 extends through the strap hole 310 on the second strap body 30 into the second receiving area formed by the second receiving portion 2320 of the first limiting member 230. The second receiving area can restrict the movement of the second protrusion 2230, thereby restricting the movement of the first cover plate 210 and the second cover plate 220 along the length direction (Y direction) and the width direction (X direction). Furthermore, by separating the second connecting portion 2310 of the first limiting member 230 and the first cover plate 210, the second cover plate 220 will be exposed, which can better achieve the separation of the first cover plate 210 and the second cover plate 220.

[0116] When the cover plate assembly is used to connect the first strap body 10 and the second strap body 30 in the watch strap, since the first cover plate 210 and the first strap body 10 are fixedly connected, and the second protrusion 2230 on the second cover plate 220 can extend through the strap hole on the second strap body 30 to the first receiving area, the first cover plate 210 and the second cover plate 220 can be separated by separating the second connecting part 2310 of the first limiting member 230 and the first cover plate 210. After the first cover plate 210 and the second cover plate 220 are separated, the second protrusion 2230 can be adjusted to pass through another strap hole until the size of the second strap body 30 can be adapted to the user's wrist circumference.

[0117] In one possible implementation, see Figure 9 and Figure 10 The second connecting portion 2310 and the first protrusion 2220 are rotatably connected; after the first limiting member 230 is engaged with the first cover plate 210, the second connecting portion 2310 and the first protrusion 2220 are magnetically connected. In some examples, the rotatable connection between the second connecting portion 2310 and the first cover plate 210 can be a hinge connection or a bearing connection.

[0118] Since the second connecting part 2310 and the first protrusion 2220 are rotatably connected, by rotating the second connecting part 2310 or the first protrusion 2220, the relative position between the first limiting member 230 and the first cover plate 210 can be changed, and the second protrusion and the second receiving area of ​​the second cover plate 220 can be separated, which is beneficial to the separation of the first cover plate 210 and the second cover plate 220.

[0119] In some possible implementations, the second connecting portion 2310 and the first cover plate 210 are rotatably connected in at least one of hinge connection and bearing connection. For example, see Figure 12The second connecting part 2310 is provided with a first hole, and the first cover plate 210 is provided with a second hole. The first rotating shaft 240 passes through the first hole and the second hole to realize the rotatable connection between the first connecting part 2120 and the first cover plate 210.

[0120] The magnetic connection between the first cover plate 210 and the first limiting member 230 is explained below. Of course, the first cover plate 210 and the first limiting member 230 may also include other magnetic connection methods. The following embodiments do not limit the magnetic connection between the first cover plate 210 and the first limiting member 230.

[0121] In some embodiments, the first cover plate 210 is provided with a groove opening towards the first limiting member 230, and a magnetic component is disposed within the groove of the first cover plate 210; the first limiting member 230 is provided with a groove opening towards the first cover plate 210, and a magnetic component is disposed within the groove of the first limiting member 230; after the first cover plate 210 and the first limiting member 230 are engaged, the magnetic components in the first cover plate 210 and the first limiting member 230 attract each other. The arrangement of the groove and its magnetic component in the first limiting member 230 is similar to the arrangement of the groove and its magnetic component in the second cover plate 220 described above, and will not be repeated here.

[0122] In some other embodiments, see Figure 14 The first limiting member 230 is provided with a groove with an opening facing the first cover plate 210, and a magnetic component is provided in the groove of the first limiting member 230; the first limiting member 230 is made of magnetic material, and the material of the first limiting member 230 can be metal; after the first cover plate 210 and the first limiting member 230 are fastened together, the magnetic component in the first limiting member 230 will attract the first cover plate 210.

[0123] For example, the magnetic contact area 2121 of the first connecting portion 2120 of the first cover plate 210 is made of magnetic material; the first protrusion 2220 of the first limiting member 230 is provided with two grooves with openings facing the first cover plate 210, one groove is provided with a magnetic component 2310a and a magnetic suction cup 2310b, and the other groove is provided with a magnetic component 2310c and a magnetic suction cup 2310d; after the first cover plate 210 and the first limiting member 230 are engaged, the magnetic components 2310a and 2310c will respectively attract the first cover plate 210, so as to realize the magnetic connection between the first cover plate 210 and the first limiting member 230.

[0124] In some other embodiments, the first cover plate 210 is provided with a groove with an opening facing the first limiting member 230, and a magnetic component is provided in the groove of the first cover plate 210; the first limiting member 230 is made of a magnetic material; after the first cover plate 210 and the first limiting member 230 are fastened together, the magnetic component in the first cover plate 210 will attract the first limiting member 230.

[0125] For example, see Figure 15 The magnetic contact area 2121 of the first connecting portion 2120 of the first cover plate 210 is provided with two grooves with openings facing the first limiting member 230. One groove is provided with a magnetic component 2121e and a magnetic chuck 2121f, and the other groove is provided with a magnetic component 2121g and a magnetic chuck 2121h. The first protrusion 2220 of the first limiting member 230 is made of magnetic material. After the first cover plate 210 and the first limiting member 230 are engaged, the magnetic components 2121e and 2121g will respectively attract the first limiting member 230 to achieve a magnetic connection between the first cover plate 210 and the first limiting member 230.

[0126] In some embodiments, see Figure 16 The magnetic contact area 2121 of the first connecting portion 2120 of the first cover plate 210 is provided with two grooves opening towards the first limiting member 230. One groove contains sub-magnetic components 21211e, 21212e, 21213e, and a magnetic chuck 2121f along the length direction (Y direction). The other groove contains sub-magnetic components 21211g, 21212g, 21213g, and a magnetic chuck 2121h along the length direction. The first protrusion 2220 of the first limiting member 230 is provided with two grooves opening towards the two grooves. One groove contains sub-magnetic components 2311a and 2311h along the length direction. 312a, sub-magnetic component 2313a, and magnetic chuck 2210b are provided in another groove, and sub-magnetic components 2311c, 2312c, 2313c, and magnetic chuck 2210d are provided along the length direction; sub-magnetic components 21211e and 2311a attract each other, sub-magnetic components 21212e and 2312a attract each other, sub-magnetic components 21213e and 2313a attract each other, sub-magnetic components 21211g and 2311c attract each other, sub-magnetic components 21212g and 2312c attract each other, and sub-magnetic components 21213g and 2313c attract each other.

[0127] When the magnetic components are set in the same area, a single magnetic component is split into multiple sub-magnetic components. The multiple sub-magnetic components in the first cover plate 210 will attract each other to the multiple sub-magnetic components in the first limiting member 230. The magnetic attraction effect of the first cover plate 210 and the first limiting member 230 is better, which can significantly reduce the thickness of the watch strap, achieve a thinner watch strap, and thus improve the wearing experience of the watch strap.

[0128] In some embodiments, magnetic component 2121e, magnetic component 2121g, magnetic component 2310a, magnetic component 2310c, sub-magnetic component 21211e, sub-magnetic component 21212e, sub-magnetic component 21213e, sub-magnetic component 2311a, sub-magnetic component 2312a, sub-magnetic component 2313a, sub-magnetic component 21211g, sub-magnetic component 21212g, sub-magnetic component 21213g, sub-magnetic component 2311c, sub-magnetic component 2312c, and sub-magnetic component 2313c each independently include at least one of ferromagnetic material or ferrimagnetic material. For example, the ferromagnetic material may be a magnet.

[0129] In some embodiments, the first belt body 10 and the first cover plate 210 are fixedly connected by a hinge connection (e.g., see...). Figure 12 and Figure 13 The first belt body 10 has a third hole at its end, and the first cover plate 210 has a fourth hole. A second rotating shaft 250 passes through the third and fourth holes to achieve one of the following connections: pin connection, welding connection (e.g., welding the first belt body 10 to the first cover plate 210), screw connection (e.g., fixing the first belt body 10 to the first cover plate 210 with screws), or snap-fit ​​connection. This provides a good connection between the first belt body 10 and the first cover plate 210. Of course, other possible connection structures can also be used to connect the first belt body 10 and the first cover plate 210.

[0130] Figure 17 A three-dimensional structural diagram of another watch strap provided in an embodiment of this application; Figure 18 for Figure 17 A schematic diagram of the cross-sectional structure of the watch strap along the E1-E2 plane; Figure 19 A cross-sectional structural schematic diagram of another watch strap provided in this application embodiment; Figure 20 for Figure 17 The diagram shows a disassembled structure of the cover plate assembly in the watch strap. That is, Figures 17 to 19 These are schematic diagrams showing the connection between the cover plate assembly and the first and second belt bodies. Figure 20 This is a schematic diagram of the disassembled structure of the cover plate assembly.

[0131] This application provides another cover plate assembly, see [link to embodiment]. Figure 17 , Figure 18 and Figure 20 The cover plate assembly includes: a first cover plate 210, a second cover plate 220, and a second limiting member 260. The second cover plate 220 is disposed between the first cover plate 210 and the second limiting member 260. After the first cover plate 210 and the second cover plate 220 are engaged, they are magnetically connected. The second limiting member 260 includes a limiting part 2610 and a rotating part 2620. The limiting part 2610 and the second cover plate 220 are rotatably connected, and a clamping space is formed between the rotating part 2620 and the second cover plate 220. In some examples, the rotatable connection between the limiting part 2610 and the second cover plate 220 includes a hinge connection and a bearing connection. For example, see... Figure 19 The limiting part 2610 is provided with a fifth hole, and the second cover plate 220 is provided with a sixth hole. The third rotating shaft 280 passes through the fifth hole and the sixth hole to realize the rotatable connection between the limiting part 2610 and the second cover plate 220.

[0132] After the first cover plate 210 and the second cover plate 220 are engaged, they are magnetically connected, facilitating the connection and disassembly of the first cover plate 210 and the second cover plate 220. The rotating part 2620 and the second cover plate 220 are rotatably connected, forming a clamping space between them. This clamping space can be used to clamp the structure to be connected (such as the second belt 30). By adjusting the rotating part 2620, the position of the rotating part 2620 clamping the structure to be connected can be adjusted, allowing the second cover plate 220 to be adjustablely connected to the target position of the structure to be connected. For example, in Figure 17 and Figure 20 In this process, rotating the end of the rotating part 2620 away from the second cover plate 220 can loosen the structure to be connected, while rotating the end of the rotating part 2620 towards the second cover plate 220 can adjust the position of the rotating part 2620 clamping the structure to be connected, and the second cover plate 220 can be adjusted to be connected to the target position of the structure to be connected.

[0133] In some embodiments, when the cover plate assembly is used to connect the first strap body 10 and the second strap body 30 in the watch strap, the watch strap includes the first strap body 10, the second strap body 30, and the second limiting member 260. The first strap body 10 can be fixedly connected to the first cover plate 210. The second strap body 30 (i.e., the structure to be connected described above is the second strap body 30) can be disposed in the clamping space formed between the rotating part 2620 and the second cover plate 220. By adjusting the rotating part 2620, the position of the rotating part 2620 clamping the second strap body 30 can be adjusted, thereby adjusting the size of the second strap body 30 according to user needs. In this way, it is easy to realize the closed-loop connection and open-loop separation of the first strap body 10 and the second strap body 30, thereby realizing the wearing and separation of the watch strap. In addition, only magnetic materials (such as magnetic components or magnetic materials) need to be provided on the first cover plate 210 and the second cover plate 220. The watch strap has a lower weight and better texture, and the user has a better wearing experience when wearing the watch strap, which is conducive to meeting the increasingly higher requirements of users.

[0134] In some embodiments, the second belt 30 can be a flexible material. For example, the flexible material can be a woven material, including materials such as nylon and canvas. In some embodiments, the first belt 10 can be made of a rigid or flexible material. For example, the first belt 10 can be made of an adhesive or a woven material. Of course, the first belt 10 can also be made of other materials, and this embodiment does not constitute a limitation.

[0135] In some embodiments, see Figure 18 , Figure 19 and Figure 20 The watch strap also includes a fastener 270, which is disposed on the side of the first strap body 10 away from the first cover plate 210. The first strap body 10 can be fixedly disposed between the first cover plate 210 and the fastener 270, thus achieving a fixed connection between the first strap body 10 and the first cover plate 210. See example. Figure 18 and Figure 19 The first belt body 10 has a through hole, and the first cover plate 210 has a protrusion corresponding to the through hole in the first belt body 10. The protrusion on the first cover plate 210 can be passed through the through hole in the first belt body 10 firstly, and then the fixing member 270 can be positioned on the side of the first belt body 10 away from the first cover plate 210. A screw 290 is then passed through the through hole of the fixing member 270, thus fixing the first belt body 10 between the first cover plate 210 and the fixing member 270. Of course, the first belt body 10 and the first cover plate 210 can also be fixedly connected by means of pins or other methods.

[0136] In some embodiments, see Figure 17 and Figure 19The first cover plate 210 is provided with a groove with an opening facing the second cover plate 220, and a magnetic component is provided in the groove of the first cover plate 210; the second cover plate 220 is provided with a groove with an opening facing the first cover plate 210, and a magnetic component is provided in the groove of the second cover plate 220; after the first cover plate 210 and the second cover plate 220 are fastened together, the groove in the first cover plate 210 is accommodated in the groove in the second cover plate 220 (the internal size of the groove in the first cover plate 210 may be slightly larger than the external size of the groove in the second cover plate 220); and the magnetic component in the first cover plate 210 and the magnetic component in the second cover plate 220 attract each other.

[0137] The magnetic components in the first cover plate 210 and the second cover plate 220 attract each other, ensuring a good magnetic connection and limiting movement of the two covers in the thickness direction (Z direction). After the first cover plate 210 and the second cover plate 220 are engaged, the groove in the first cover plate 210 is accommodated in the groove in the second cover plate 220, further limiting movement of the two covers in the length direction (Y direction) and width direction (X direction). This effectively restricts movement of the first cover plate 210 and the second cover plate 220 in the length, width, and thickness directions. Furthermore, placing the magnetic components in the grooves of the first cover plate 210 and the second cover plate 220 prevents them from being directly exposed, improving the aesthetics of the watch strap.

[0138] For example, see Figure 18 and Figure 20 The first cover plate 210 has a groove with an opening facing the second cover plate 220. Sub-magnetic components 211a, 211b, and 211c are disposed within the groove in the first cover plate 210. The second cover plate 220 has a groove with an opening facing the first cover plate 210. Sub-magnetic components 221a, 221b, and 221c are disposed within the groove in the second cover plate 220. After the first cover plate 210 and the second cover plate 220 are engaged, the groove in the first cover plate 210 is accommodated within the groove in the second cover plate 220. Sub-magnetic components 211a and 221a attract each other, sub-magnetic components 211b and 221b attract each other, and sub-magnetic components 211c and 221c attract each other. Of course, the arrangement of the grooves and magnetic components in the first cover plate 210 and the second cover plate 220 in this solution can refer to the arrangement scheme of the above embodiment, and will not be repeated here. In addition, the groove in the first cover plate 210 is provided with a magnetic suction cup 212, and the groove in the second cover plate 220 is provided with a magnetic suction cup 222. The magnetic suction cups 212 and 222 have similar functions to the magnetic suction cups mentioned above, and will not be described in detail here.

[0139] In some embodiments, see Figure 19 The first cover plate 210 is provided with a groove with an opening facing the second cover plate 220, and a magnetic component 211 is provided in the groove of the first cover plate 210; the second cover plate 220 is provided with a third protrusion 223 facing the groove of the first cover plate 210, and the third protrusion 223 is made of magnetic material; after the first cover plate 210 and the second cover plate 220 are fastened together, the third protrusion 223 is accommodated in the groove of the first cover plate 210; the magnetic component in the groove of the first cover plate 210 will attract the third protrusion 223.

[0140] The magnetic component in the groove of the first cover plate 210 can attract the third protrusion 223, which helps to ensure a good magnetic connection between the first cover plate 210 and the second cover plate 220 and helps to limit the movement of the first cover plate 210 and the second cover plate 220 in the thickness direction. In addition, after the first cover plate 210 and the second cover plate 220 are engaged, the third protrusion 223 is accommodated in the groove of the first cover plate 210, which helps to limit the movement of the first cover plate 210 and the second cover plate 220 in the length direction and the width direction. In this way, the movement of the first cover plate 210 and the second cover plate 220 in the length direction, the width direction and the thickness direction can be effectively limited.

[0141] For example, see Figure 19 The first cover plate 210 has a groove with an opening facing the second cover plate 220. A magnetic component is disposed within the groove of the first cover plate 210, or multiple sub-magnetic components can be replaced. The second cover plate 220 has a third protrusion 223 facing the groove of the first cover plate 210, and the third protrusion 223 is made of a magnetic component. After the first cover plate 210 and the second cover plate 220 are engaged, the third protrusion 223 is accommodated within the groove of the first cover plate 210. The magnetic component in the groove of the first cover plate 210 will attract the third protrusion 223. Alternatively, the second cover plate 220 can be configured such that it has a groove with an opening facing the first cover plate 210, and a magnetic component is disposed within the groove of the second cover plate 220; the first cover plate 210 also has a fourth protrusion facing the groove of the second cover plate 220, and the fourth protrusion is made of a magnetic component. This configuration produces the following beneficial effects and... Figure 18 The technical effects produced by the proposed solutions are similar and will not be elaborated upon here.

[0142] In one possible implementation, see Figure 19The thickness of the second belt 30 is L1, and the dimensions of the limiting portion 2610 of the second limiting member 260 and the second cover plate 220 along the thickness direction are L2. The ratio of L1 to L2 is 1:(0.5-0.7). For example, the ratio of L1 to L2 can be 1:0.5, 1:0.55, 1:0.6, 1:0.65, or 1:0.7.

[0143] By controlling L1 and L2 within the range of 1:(0.5-0.7), the amount of the second belt 30 clamped by the limiting part 2610 is moderate, and the clamping force applied by the limiting part 2610 to the second belt 30 is moderate. By adjusting the rotating part 2620, it is easy to loosen and clamp the second belt 30. In addition, it can effectively alleviate the problem that if the ratio of L1 is too high, it may cause the limiting part 2610 to clamp the second belt 30 too much, or the clamping force applied by the limiting part 2610 to the second belt 30 to be too large, making it difficult to loosen the second belt 30 by adjusting the rotating part 2620. It can also effectively alleviate the problem that if the ratio of L2 is too high, it may cause the limiting part 2610 to clamp the second belt 30 too little, or the clamping force applied by the limiting part 2610 to the second belt 30 to be too small, making it difficult to clamp the second belt 30 by adjusting the rotating part 2620.

[0144] This embodiment provides a wearable device, which includes: a watch body; a watch strap as described in the previous embodiment; wherein one end of the watch body is connected to a first strap body 10 in the watch strap, and the other end of the watch body is connected to a second strap body 30 in the watch strap. In this way, because the weight of the watch strap in the wearable device is significantly reduced, the texture of the watch strap is greatly improved, which can enhance the user's wearing experience of the wearable device.
