Description

Technical Field

[0001] This application relates to the field of electronic technology, and in particular to a watch strap and wearable device. Background Technology

[0002] As a portable timekeeping tool, the watch has always been an indispensable part of people's lives. With the development of electronic technology, watches have gradually evolved into products such as smart bracelets and smartwatches, with more diversified functions, and can also serve as fashion accessories to showcase personal taste and style.

[0003] The watch strap has a significant impact on the watch's appearance, but watch straps in this technology generally suffer from the problem of not being both aesthetically pleasing and soft against the skin. Utility Model Content

[0004] This application provides a watch strap and wearable device that can solve the problem that watch straps in related technologies cannot simultaneously achieve both aesthetic appeal and a soft, skin-friendly feel.

[0005] The technical solution is as follows:

[0006] On the one hand, a watch strap is provided, the watch strap comprising: a plurality of beaded units arranged in series;

[0007] Each of the bead segments includes a bead segment body, and at least one connecting ring is provided on the side of each bead segment body facing another adjacent bead segment body;

[0008] The two connecting rings on the adjacent bead sections are movably connected to each other, so that the two adjacent bead sections are movably connected.

[0009] In this embodiment of the watch strap, among several series-arranged bead units, each bead unit has at least one connecting ring on the side facing another bead unit. Adjacent bead units are movably connected through the movable connection of the connecting rings. The structure is simple, aesthetically pleasing, and the bead units have better mobility, which can improve the soft and skin-friendly effect of the watch strap.

[0010] In some possible implementations, the connecting ring of each bead unit is integrally formed and connected to the bead body;

[0011] And / or,

[0012] The connecting ring has a closed structure.

[0013] With the above arrangement, the connecting ring can be integrally formed with the bead link body, and during the forming process, both ends of the connecting ring are integrally connected to the bead link body, achieving a closed connection. The closed connecting ring is integrally formed and connected to the bead link unit, which helps reduce the processing and manufacturing costs of the watch strap.

[0014] In some possible implementations, the included angle between the projections of the two interlocking connecting rings onto the side of the bead body ranges from 70 to 110 degrees.

[0015] With the above arrangement, the two interlocking connecting rings are arranged at an angle of 70-110 degrees and staggered to each other. When the two connecting rings are interlocked, the two bead bodies have more flexible rotational freedom, which is conducive to achieving a flexible and skin-friendly effect for the watch strap.

[0016] In some possible implementations, the connecting ring has a spiral structure.

[0017] With the above arrangement, the two interlocking connecting rings are spiral-shaped. The spiral connecting rings have a smooth shape and no large surface undulations, which helps to improve the flexibility and smoothness of the bead joint units during mutual rotation.

[0018] In some possible implementations, the two interlocking connecting rings are coaxial and intertwined.

[0019] With the above arrangement, the two interlocking connecting rings are spiral-shaped and have the characteristics of being coaxial and intertwined. When the two connecting rings are interlocked, the two bead bodies have more flexible and smooth rotational freedom, which is conducive to achieving a flexible and skin-friendly effect of the watch strap.

[0020] In some possible implementations, several connecting rings located on the same side of the bead body have the same structure and coincident helical axes, which are parallel to the side of the bead body.

[0021] With the above arrangement, the axes of several connecting rings on the same side coincide, so that the rotational degrees of freedom formed after the connecting rings are nested together have a high degree of consistency. This is beneficial to improving the rotational degrees of freedom between the bead joint units and ensuring the working consistency of the connecting rings at various points between two bead joint units.

[0022] In some possible implementations, the side of the bead body is provided with a plurality of clearance grooves, the position of each clearance groove corresponding to the position of one of the connecting rings, and the clearance groove is used to accommodate another connecting ring that is movably sleeved with the connecting ring.

[0023] With the above arrangement, the side of the bead link body is provided with a relief groove, which can be used to accommodate the connecting ring of the opposite bead link unit. Thus, the connecting ring will not occupy the gap between the bead link units, allowing the bead link units to be spaced smaller. From the appearance, the bead link units in the watch strap are arranged compactly, and the connecting ring is hidden in the relief groove, making the watch strap more aesthetically pleasing.

[0024] In some possible implementations, the clearance groove is a spiral groove that corresponds to the shape of the connecting ring to be accommodated.

[0025] With the above arrangement, the shape of the clearance groove corresponds to the shape of the connecting ring it is to accommodate, and the connecting ring can move smoothly within the clearance groove, which helps to improve the rotation flexibility and smoothness of multiple bead units in the watch strap.

[0026] In some possible implementations, each of the bead units is provided with a positioning groove; the watch strap also includes a fastener, which is sleeved on the bead unit and engages with the positioning groove.

[0027] With the above arrangement, the watch strap can be positioned and fastened using the positioning grooves on the surface of the bead unit, so that the watch strap can be fastened to another watch strap.

[0028] In some possible implementations, one of the two beaded units at both ends of the plurality of beaded units is provided with a connecting shaft for mounting the watch strap.

[0029] In this embodiment, the watch strap can be rotatably connected to the wearable device via a connecting pivot, so that the wearable device can be worn on the wrist of the human body using the watch strap.

[0030] In some possible implementations, several of the bead units are 3D printed structures. For example, the bead units are 3D printed metal structures.

[0031] On the other hand, a wearable device is provided, the wearable device comprising: a device body and the watch strap described in this application, the device body being movably connected to the watch strap.

[0032] The wearable device in this embodiment uses the watch strap of this application and has all the beneficial technical effects of all embodiments herein. Attached Figure Description

[0046] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0047] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0048] On the one hand, combined with Figure 1 and Figure 2 As shown, this embodiment provides a watch strap, which includes a plurality of beaded units 1 arranged in series.

[0049] Each bead unit 1 includes a bead body 11, and at least one connecting ring 12 is provided on the side of the bead body 11 facing another adjacent bead body 11.

[0050] Two connecting rings 12 on adjacent bead body 11 are movably connected to each other so that the two bead units 1 are movably connected.

[0051] In this embodiment of the watch strap, among a plurality of beaded units 1 arranged in series, each beaded unit 1 has a connecting ring 12 on each of its opposite sides. Adjacent beaded units 1 can be connected by the movable connection of the connecting ring 12. The structure is simple and aesthetically pleasing. Moreover, the beaded units 1 have better mobility, which can improve the soft and skin-friendly effect of the watch strap.

[0052] In some possible implementations, the closed connecting ring 12 is integrally formed with the bead body 11, including but not limited to 3D printing, injection molding, die casting, etc.

[0053] Combination Figure 2 As shown, in some possible implementations, the connecting ring 12 of each bead unit is integrally formed and connected to the bead body 11.

[0054] With the above arrangement, the connecting ring 12 can be integrally formed with the bead body 11, and during the forming process, the two ends of the connecting ring 12 are integrally connected with the bead body 11. The connecting ring 12 has higher structural reliability and does not require subsequent assembly, which is conducive to improving the production efficiency of the watch strap and reducing processing costs.

[0055] Combination Figure 2 As shown, in some possible implementations, the connecting ring 12 is formed as a closed structure.

[0056] In this embodiment, the closed connecting ring 12 is integrally formed and connected to the bead unit 1, and is integrally formed with the bead body 11, which helps to reduce the processing and manufacturing cost of the watch strap.

[0057] In some possible implementations, the connecting ring 12 can be an open structure.

[0058] In some possible implementations, the angle between the projections of the two interlocking connecting rings 12 onto the side of the bead body 11 ranges from 70 to 110 degrees.

[0059] With the above arrangement, the two interlocking connecting rings 12 are arranged at an angle of 70-110 degrees and staggered with each other. When the two connecting rings 12 are interlocked, the two bead bodies 11 have more flexible rotational freedom, which is conducive to achieving a flexible and skin-friendly effect of the watch strap.

[0060] For example, the included angle α between the projections of the two interlocking connecting rings 12 can be 70 degrees, 80 degrees, 90 degrees, 100 degrees, 110 degrees, etc.

[0061] Combination Figure 2 As shown, in some possible implementations, the connecting ring 12 has a spiral structure.

[0062] In this embodiment, the spiral connecting ring 12 has a smoother shape and a surface without large undulations, which helps to improve the flexibility and smoothness of the bead unit 1 during mutual rotation.

[0063] For example, a spiral structure refers to the shape of a single connecting ring that is at least a portion of a spiral, such as simply a portion of a spiral cut out along a plane parallel to the spiral axis.

[0064] Combination Figure 3 and Figure 4 As shown, in some possible implementations, the two interlocking connecting rings 12 are coaxial and intertwined.

[0065] With the above arrangement, the two connecting rings 12 that are nested together are spiral-shaped and have the characteristics of being coaxial and intertwined. When the two connecting rings 12 are nested together, the two bead bodies 11 have more flexible and smooth rotational freedom, which is conducive to achieving a flexible and skin-friendly effect of the watch strap.

[0066] Combination Figure 2 , Figure 3 and Figure 4 As shown, in some possible implementation schemes, several connecting rings 12 located on the same side of the bead body 11 have the same structure and their spiral axes coincide, and the spiral axes are parallel to the side of the bead body 11.

[0067] With the above arrangement, the structures of several connecting rings 12 on the same side are the same and their helical axes coincide, so that the rotational degrees of freedom formed after the connecting rings 12 are nested together have a high degree of consistency, which is beneficial to improve the rotational degrees of freedom between the bead joint units 1 and ensure the consistency of the movement of the connecting rings 12 at each point between the two bead joint units 1.

[0068] In some possible implementations, if several connecting rings 12 have the same structure, then the pitch, helix radius, helix lead, and helix angle of the several helical connecting rings 12 are all the same. When several connecting rings 12 are axially connected in sequence, they can be regarded as a relatively long helical structure.

[0069] Combination Figures 3 to 6 As shown, in some possible implementation schemes, the side of the bead body 11 is provided with a number of clearance grooves 13, and the position of each clearance groove 13 corresponds to the position of a connecting ring 12. The clearance groove 13 is used to accommodate the connecting ring 12 of another bead unit 1 that is sleeved with the connecting ring 12.

[0070] With the above arrangement, the side of the bead body 11 is provided with a relief groove 13, which can be used to accommodate the connecting ring 12 of the opposite bead unit 1. Thus, the connecting ring 12 will not occupy the gap between the bead units 1, so that the bead units 1 can be spaced smaller. From the appearance, the bead units 1 in the watch strap are arranged compactly, and the connecting ring 12 is hidden in the relief groove 13, making the watch strap more aesthetically pleasing.

[0071] Combination Figures 4 to 6 As shown, in some possible implementations, the clearance groove 13 is a spiral groove, and the clearance groove 13 corresponds to the shape of the connecting ring 12 to be accommodated.

[0072] With the above arrangement, the shape of the clearance groove 13 corresponds to that of the connecting ring 12 to be accommodated, and the connecting ring 12 can move smoothly within the clearance groove 13, thereby improving the rotation flexibility and smoothness of the multiple bead units 1 in the watch strap.

[0073] For example, each clearance groove 13 is opposite to the spiral direction of the corresponding connecting ring 12.

[0074] The function of the clearance groove 13 is to accommodate the connecting ring 12. When the connecting ring 12 is helical, the clearance groove 13 can also be helical. However, the pitch, helical radius, and helical lead of the clearance groove 13 are slightly larger than those of the connecting ring 12, which can ensure that the connecting ring 12 can rotate freely in the clearance groove 13.

[0075] Combination Figure 4 and Figure 6 These are cross-sectional views of the watch strap along different directions, among which... Figure 4 The cross-sectional direction is perpendicular to the rotation axis of bead unit 1. Figure 6 The cross-sectional direction is parallel to the rotation axis of the bead unit 1.

[0076] To clearly describe the technical solution of movably connecting two adjacent bead joint units 1 using a connecting ring 12, the bead joint unit 1 on the left is designated as the first bead joint unit 1a, and the bead joint unit 1 on the right is designated as the second bead joint unit 1b. The first bead joint unit 1a includes a first bead joint body 11a, a connecting ring 12a, and a first clearance groove 13a. The second bead joint unit 1b includes a second bead joint body 11b, a second connecting ring 12b, and a second clearance groove 13b.

[0077] refer to Figure 4 As can be seen, the connecting ring 12a and the second connecting ring 12b are intertwined. The connecting ring 12a bends and extends into the second clearance groove 13b, and the second connecting ring 12b bends and extends into the first clearance groove 13a. Moreover, the connecting ring 12a extends spirally from bottom to top, and the second connecting ring 12b extends spirally from top to bottom. The spiral directions of the two connecting rings 12 are exactly opposite.

[0078] refer to Figure 6 Similarly, it can be seen that the connecting ring 12a and the second connecting ring 12b are interlocked. The connecting ring 12a bends and extends into the second clearance groove 13b, and the second connecting ring 12b bends and extends into the first clearance groove 13a, thus realizing the movable connection of the two connecting rings 12.

[0079] In some possible implementations, at least one of the beaded units 1 is provided with a positioning groove 14; the watch strap also includes a fastener (not shown in the figure), which is fitted onto the beaded unit 1 and positioned and engaged with the positioning groove 14.

[0080] With the above arrangement, the watch strap can be positioned and fastened using the positioning groove 14 on the surface of the bead unit 1, so that the watch strap can be fastened to another watch strap.

[0081] In some possible implementations, at least one of the two beaded units 1 at both ends of several beaded units 1 is provided with a connecting shaft (not shown in the figure), which is used for the installation of the watch strap.

[0082] With the above arrangement, the watch strap can be rotatably connected to the wearable device via a connecting pivot, so that the wearable device can be worn on the wrist of the human body using the watch strap.

[0083] In some possible implementations, several bead units 1 are 3D printed structures. For example, the bead unit 1 is a 3D printed metal structure.

[0084] For example, the bead unit 1 is a structure formed by metal powder 3D printing. Specifically, metal powder is melted layer by layer using a high-energy beam (laser, electron beam, etc.) and finally stacked to form a dense three-dimensional metal part. Compared with traditional subtractive manufacturing (such as cutting and grinding) or equal-material manufacturing (such as casting and forging), its core advantage lies in its ability to achieve near-net-shape forming of complex structures. The bead body 11 and the connecting ring 12 on it can be integrally processed, resulting in high processing efficiency and low processing cost.

[0085] For example, all the beaded units 1 in the entire watch strap are printed in one piece using metal powder 3D printing technology, which ensures that the connecting rings 12 of adjacent beaded units 1 can be nested together during the forming process.

[0086] In some possible implementations, the processing steps for the watch strap may include:

[0087] 1. 3D Model Design and Slicing: The three-dimensional model of the watch strap is constructed using software, and then the model is layered using slicing software (each layer is usually 10-50μm thick) to generate the scanning path for each layer.

[0088] 2. Powder spreading: The powder spreading device evenly spreads the metal powder on the current layer of the printing platform.

[0089] 3. High-energy beam melting: Heat sources such as lasers, electron beams or plasma beams scan along the slice path to melt the metal powder in the current layer, causing it to fuse with the solidified metal in the lower layer.

[0090] 4. Layer by layer: The printing platform descends by one layer thickness, repeating the "powder spreading-melting" process until the watch strap is completely formed.

[0091] On the other hand, this embodiment provides a wearable device, which includes a device body and a watch strap of this application, wherein the device body and the watch strap are movably connected.

[0092] The wearable device in this embodiment uses the watch strap of this application and has all the beneficial technical effects of all embodiments herein.

[0093] In some possible implementations, wearable devices can be timekeeping devices, such as watches (mechanical watches, quartz watches, electronic watches), electronic devices, such as smartwatches, smart bracelets, children's phones, etc., or wrist ornaments, such as decorative wristbands, etc.

[0094] In some possible implementations, when the wearable device is a watch, there are two watch straps. The two straps are rotatably connected to opposite sides of the device body, which can fit against the front of the wrist. The two straps wrap around the back of the wrist from the sides and connect to each other. The connection between the two straps can be achieved through methods including, but not limited to, magnetic connection, buckle connection, etc.
