[0001] The application claims priority to the Chinese patent application No. 202410949413.8, filed on July 15, 2024, and entitled "Watchband, wearable device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of wearable devices, in particular to a wearable device and a watchband that can be applied to the wearable device. BACKGROUND

[0003] A wearable device generally refers to a micro electronic device that can be worn on the body for activities, and basically includes a smart watch and a smart bracelet. The smart watch and the smart bracelet can be used independently or as a portable accessory of a mobile terminal.

[0004] The wearable device mainly includes a watch dial and a watchband. The watchband includes a plurality of chain links connected in sequence. Adjacent two chain links are mostly fixedly connected or rotatably connected, so that the softness of the entire watchband is poor, and the wearing experience is reduced. SUMMARY

[0005] The present application provides a wearable device and a watchband that can be applied to the wearable device. The purpose is to improve the softness of the watchband and improve the wearing experience.

[0006] To achieve the above purpose, the embodiments of the present application adopt the following technical solutions:

[0007] In a first aspect, the present application provides a watchband that can be applied to a wearable device, such as a watch or a bracelet.

[0008] The watchband provided by the present application includes a plurality of chain links, a first connecting shaft and a second connecting shaft. The axial direction of the first connecting shaft and the axial direction of the second connecting shaft are both parallel to the width direction of the watchband. The plurality of chain links arranged along the width direction of the watchband includes a plurality of first chain links and a plurality of second chain links. One second chain link is connected with two first chain links, and one first chain link is connected with two second chain links. The first chain links and the second chain links are arranged in a staggered manner in the length direction of the watchband. The first chain link and the two second chain links connected with the first chain link enclose a first accommodating cavity for accommodating the first chain link located on one side. The second chain link and the two first chain links connected with the second chain link enclose a second accommodating cavity for accommodating the second chain link located on the other side. The first connecting shaft connects the two first chain links and the second chain link located in the second accommodating cavity. The second connecting shaft connects the two second chain links and the first chain link located in the first accommodating cavity.

[0009] The plurality of links in the watchband are arranged in a staggered manner in the length direction of the watchband, so that the softness of the watchband is improved, the wearing comfort of the watchband is improved, and the user experience is improved. In addition, the plurality of links arranged in a staggered manner can also improve the appearance of the watchband.

[0010] In an implementable manner, the adjacent first link and the second link are fixedly connected.

[0011] In this example, the first link and the second link are fixed together, which can simplify the manufacturing process.

[0012] In an implementable manner, a groove is formed at the connection between the first link and the second link, the groove is recessed from the first surface to the second surface of the watchband, there is a gap between the bottom surface of the groove and the second surface, and the direction from the first surface to the second surface is parallel to the thickness direction of the watchband.

[0013] The groove is formed between the first link and the second link, for example, the surface with the groove is the side that can be seen by the user when wearing the watchband, so that the appearance of the watchband is improved.

[0014] In an implementable manner, the second surface is a plane.

[0015] For example, the second surface is the side that is close to the skin of the user when wearing the watchband, and the use of a plane can improve the wearing comfort of the watchband.

[0016] In an implementable manner, the first connecting shaft includes a first shaft segment and a second shaft segment, the first shaft segment and the second shaft segment are disconnected; along the axial direction of the first shaft segment and the second shaft segment, the first shaft segment and the second shaft segment each include a first part and a second part, the radial dimension of the first part is greater than the radial dimension of the second part; the part of the link located at the end in the width direction of the watchband is fixedly connected with the first part; the link located between the two ends in the width direction of the watchband is rotatably connected with the second part.

[0017] The use of the first part with a larger radial dimension to be fixedly connected with the link can prevent the link from moving along the first part when rotating.

[0018] In an implementable manner, the watchband further includes a fixed shaft, the axial direction of the fixed shaft is parallel to the width direction of the watchband, and the fixed shaft is located at the end of the first connecting shaft; in the width direction of the watchband, the part of the link located at the end is fixedly connected with the fixed shaft, and the link located between the ends is rotatably connected with the first connecting shaft.

[0019] In this example, the fixed shaft is arranged at the end of the connecting shaft, which can prevent the connecting shaft from moving and improve the stability of the rotation of the link.

[0020] In an implementation, the first and second links are integrated structures.

[0021] For example, the first and second links arranged along the width direction of the watchband can be integrally formed. In some alternative processes, the links can be made by forging.

[0022] In an implementation, the first and second links are separate structures.

[0023] In this implementation, each link is an independent structure.

[0024] In an implementation, the watchband further comprises a third connecting shaft, the third connecting shaft is parallel to the width direction of the watchband in the axial direction; the first and second links are connected by the third connecting shaft.

[0025] In this example, since the first and second links are separate structures, the first and second links can be connected by the third connecting shaft.

[0026] By adding the third connecting shaft, the softness of the watchband can be further improved.

[0027] In an implementation, the third connecting shaft is located between the first and second connecting shafts.

[0028] In an implementation, the watchband further comprises a limiting structure, the limiting structure is used to prevent the first link from moving along the axial direction of the first connecting shaft.

[0029] Since the first and second links are separate structures, in order to prevent the first and second links from moving along the axial direction of the connecting shaft when the first and second links rotate relative to the connecting shaft, a limiting structure can be provided to prevent the first and second links from moving along the connecting shaft.

[0030] In an implementation, the limiting structure comprises a limiting slot and a limiting column; the limiting column is arranged in the first link, the first connecting shaft has a limiting slot at a position corresponding to the limiting column, the limiting slot is arranged around the outer wall surface of the first connecting shaft in the axial direction, and the limiting column is located in the limiting slot.

[0032] In an implementation, the first and third connecting shafts are arranged in the first link, and the limiting column can be arranged between the first and third connecting shafts.

[0033] In this way, the limiting column can be used to limit the first connecting shaft and the third connecting shaft at the same time, and the structure is simplified.

[0034] In an implementable manner, the second connecting shaft and the third connecting shaft are arranged in the second chain link, and the limiting column is arranged between the second connecting shaft and the third connecting shaft.

[0036] In an implementable manner, the first chain link includes a bottom plate and a cover body arranged oppositely, the limiting column is arranged on the bottom plate, the cover body is provided with a clamping groove, and the end of the limiting column is arranged in the clamping groove.

[0037] The limiting column and the limiting groove in the example are matched to realize limiting, and thus the limiting column not only has a limiting function, but also has a function of connecting the bottom plate and the cover body.

[0038] In an implementable manner, the first connecting shaft includes an inner shaft, and outer shafts are arranged at both ends of the inner shaft; the part of the chain link located at the end is rotationally connected with the outer shaft; and the part of the chain link located between the ends is rotationally connected with the inner shaft.

[0039] The outer shaft is fixedly connected with the end of the chain link, and the inner shaft can be limited from moving.

[0063] In an implementable manner, a groove is formed in the side surface of the chain link, and the first connecting ring is fixed in the groove, and part of the first connecting ring is exposed outside the groove.

[0064] The groove is formed in the side surface of the chain link, and the connecting ring is fixed in the groove, so that the structure of the entire watchband is more compact.

[0111] An embodiment of the present application provides a wearable device, which can be a smart bracelet or a smart watch. The wearable device can be worn on a wrist to realize time display, time recording, time reporting, message notification, motion detection, heart rate monitoring, blood oxygen level detection, and the like.

[0112] The wearable device can include a watchband and a watch dial. The watchband is used to be worn around a wrist of a user to realize wearing of the wearable device, and the watch dial is used for display.

[0113] As shown in FIG. 1, FIG. 1 shows a structure of a watchband of a wearable device. The watchband 100 includes a plurality of connected links 101. The watchband 100 can be a metal or ceramic watchband.

[0114] As shown in FIG. 1, the watchband 100 includes a plurality of links 101 arranged along a length direction (e.g., the X direction in FIG. 1) of the watchband 100, and a plurality of links 101 arranged along a width direction (e.g., the Y direction in FIG. 1) of the watchband 100.

[0115] In an example, the length direction of the watchband 100 can be perpendicular to the width direction of the watchband 100, the length direction of the watchband 100 can be perpendicular to a thickness direction (e.g., the Z direction in FIG. 1) of the watchband 100, and the width direction of the watchband 100 can be perpendicular to the thickness direction of the watchband 100.

[0116] In an example, the watchband 100 includes a plurality of links 101 arranged along a length direction (e.g., the X direction in FIG. 1) of the watchband 100, and a plurality of links 101 arranged along a width direction (e.g., the Y direction in FIG. 1) of the watchband 100.

[0117] In some examples, the more degrees of freedom of rotation of the links 101, the more flexible the rotation of the links 101, and the more flexible the entire watchband, and the better the wearing comfort.

[0118] In order to make the watchband more flexible, some structures that can be implemented are provided, which are described below.

[0119] As shown in FIG. 2, FIG. 2 shows a partial structure of a watchband. The watchband includes a plurality of links 101 arranged along a length direction (e.g., the X direction) of the watchband, and a plurality of links 101 arranged along a width direction (e.g., the Y direction) of the watchband.

[0120] As shown in FIG. 3, FIG. 3 shows a connection relationship of a plurality of links 101. Adjacent two links 101 are connected by a connection structure 102.

[0121] In some examples, adjacent two links 101 are connected by a connection structure 102, which can be understood as: in the watchband 100, some adjacent two links 101 can be connected by a connection structure 102, or all links 101 can be connected by a connection structure 102. For example, as shown in FIG. 3, adjacent two links 101 along the width direction (e.g., the Y direction) of the watchband are connected by a connection structure 102, and as shown in FIG. 2, adjacent two links 101 along the length direction (e.g., the X direction) of the watchband are connected by a connection structure.

[0122] In the watchband example, the link 101 can rotate through the connecting structure 102, and the rotation axis of the link 101 includes at least two. For example, as shown in FIG. 4, the rotation axis of the link 101 can include a first axis Q1 and a second axis Q2, and the first axis Q1 and the second axis Q2 intersect.

[0123] For example, in some structures, the first axis Q1 and the second axis Q2 are both parallel to a reference plane, which can be a plane in which the length direction and the width direction of the watchband are located. It can be understood that the first axis Q1 and the second axis Q2 in the example of FIG. 4 are located in the reference plane X-Y plane, and the first axis Q1 and the second axis Q2 are not parallel but intersect.

[0124] As shown in FIG. 4, the link 101 can not only rotate around the first axis Q1, but also rotate around the second axis Q2. In this way, the link 101 has more degrees of freedom of rotation, and the rotation is more flexible, the user wears more comfortable, and the experience is better.

[0125] In other examples, the rotation axis of the link 101 can also have more, as shown in FIG. 5, including the first axis Q1, the second axis Q2, the third axis Q3 and the fourth axis Q4, and any two of the first axis Q1, the second axis Q2, the third axis Q3 and the fourth axis Q4 intersect.

[0126] For example, the first axis Q1 and the second axis Q2 are located in the X-Y plane, and the included angle between the first axis Q1 and the second axis Q2 can be less than or equal to 60°. The third axis Q3 and the fourth axis Q4 are located in the Y-Z plane, and the included angle between the third axis Q3 and the fourth axis Q4 can be less than or equal to 50°.

[0127] The above FIG. 4 and FIG. 5 only exemplarily show the positions of part of the axes, and in other examples, the axes can be located in other positions. The present application includes the examples of FIG. 4 and FIG. 5, but is not limited to these examples.

[0128] The plurality of links 101 in the example of the present application has a plurality of arrangement modes, as shown in FIG. 8, which shows one of the arrangement modes of the plurality of links 101.

[0129] In FIG. 6, the plurality of links arranged along the width direction (such as the Y direction) of the watchband includes a plurality of first links 1011 and a plurality of second links 1012, wherein one second link 1012 is connected to two first links 1011, and one first link 1011 is connected to two second links 1012.

[0130] For example, in FIG. 6, three link assemblies are shown, link assembly A, link assembly B and link assembly C, which are arranged in sequence along the length direction (e.g., the X direction) of the watchband. Each link assembly includes a plurality of first links 1011 and a plurality of second links 1012. One second link 1012 is connected to two first links 1011, and one first link 1011 is connected to two second links 1012.

[0131] Continuing to FIG. 6, in each link assembly, the first links 1011 and the second links 1012 are arranged staggered in the length direction (e.g., the X direction) of the watchband.

[0132] The staggered arrangement of the first links 1011 and the second links 1012 in the length direction of the watchband can be understood as follows: the first link 1011 protrudes towards the first side compared to the two second links 1012 adjacent thereto, and the second link 1012 protrudes towards the second side compared to the two first links 1011 adjacent thereto. The first side points in a direction parallel to the length direction (e.g., the X direction) of the watchband to the second side.

[0133] As shown in FIG. 6, in any link assembly, the first link 1011 and the two second links 1012 connected to the first link 1011 enclose a first accommodating cavity 1031 for accommodating the first link 1011 on one side (e.g., the second side in FIG. 6); and the second link 1012 and the two first links 1011 connected to the second link 1012 enclose a second accommodating cavity 1032 for accommodating the second link 1012 on the other side (e.g., the first side in FIG. 6).

[0134] As shown in FIG. 6, the plurality of links 101 are arranged in a honeycomb structure, which not only improves the appearance of the entire watchband, but also, in combination with the connection structure between adjacent two links, which allows the links to have multiple degrees of freedom of rotation, thereby making the entire watchband more flexible and more comfortable to wear.

[0135] In some examples, the plurality of links arranged in the width direction (e.g., the Y direction) of the watchband can be integrally formed. For example, as shown in FIG. 6, all the links in the link assembly A can be integrally formed, or all the links in the link assembly B can be integrally formed, or all the links in the link assembly C can be integrally formed. For another example, some of the plurality of links arranged in the width direction of the watchband can be integrally formed. For example, as shown in FIG. 6, in the link assembly A, the two first links 1011 and the second link 1012 between the two ends can be integrally formed, and the second link 1012 at the end and the first link 1011 adjacent thereto are two independent structural members.

[0136] In some other examples, the plurality of links arranged along the length direction of the watchband (e.g., the X direction) can be integrally formed. For example, the first link 1011 in the link assembly A, the first link 1011 in the link assembly B, and the first link 1011 in the link assembly C can be integrally formed, or the first link 1011 in the link assembly A and the first link 1011 in the link assembly B can be integrally formed, and the first link 1011 in the link assembly B and the first link 1011 in the link assembly C can be two separate structural members. For another example, the second link 1012 in the link assembly A, the second link 1012 in the link assembly B, and the second link 1012 in the link assembly C can be integrally formed, or the second link 1012 in the link assembly A and the second link 1012 in the link assembly B can be two separate structural members, and the second link 1012 in the link assembly B and the second link 1012 in the link assembly C can be integrally formed. The application exemplarily provides various implementation manners of the connection structure 102.

[0137] FIGS. 7 and 8 are partial structural exploded views of a watchband according to an embodiment of the application, which are used to show a structure of the connection structure 102. In this example, the connection structure 102 can include a first connection ring 1021 and a second connection ring 1022. Among two adjacent links 101, one of the links 101 is provided with the first connection ring 1021, and the other of the links 101 is provided with the second connection ring 1022. The first connection ring 1021 and the second connection ring 1022 are sleeved together, so that the two adjacent links 101 can be connected.

[0138] For example, in FIG. 7, the link 101A and the link 101B arranged along the width direction of the watchband and adjacent to each other can be connected by the first connection ring 1021 and the second connection ring 1022 sleeved together, and the link 101A and the link 101C arranged along the length direction of the watchband and adjacent to each other can be connected by the first connection ring 1021 and the second connection ring 1022 sleeved together.

[0139] In the example of FIGS. 7 and 8, the rotation of the link 101 is realized by the two connection rings sleeved together. The rotation axis of the link 101 has a plurality of directions. For example, in FIG. 7, the link 101A can rotate around the axis Q1, and can rotate around the axis Q2. The axis Q1 and the axis Q2 can both be parallel to the X-Y plane.

[0140] In FIG. 7, the link 101A can rotate around the axis Q1 within a range of 0° to 45°. The link 101A can rotate around the axis Q2 within a range of 0° to 270°.

[0141] The first connecting ring 1021 and the second connecting ring 1022 are sleeved together, which not only enables the chain link to have multiple rotational degrees of freedom, but also enables the chain link to have a translational degree of freedom, for example, the chain link can also move along the X-Y plane, and the chain link can move 1-3 mm in the X-Y plane.

[0142] In the above examples, the chain link 101 can adopt the structure shown in FIG. 9, and the chain link 101 includes multiple extension portions which are arranged at intervals along the circumference of the chain link 101, for example, the multiple extension portions can be arranged at equal intervals along the circumference of the chain link 101.

[0143] For example, the chain link 101 can include a first extension portion 1A, a second extension portion 1B, and a third extension portion 1C, and the first extension portion 1A, the second extension portion 1B, and the third extension portion 1C are arranged at equal intervals along the circumference of the chain link 101.

[0144] As shown in FIG. 9, a recess S is formed between two adjacent extension portions. In some examples, a connecting ring can be arranged on each extension portion, and a connecting ring can be arranged in each recess S.

[0145] In some examples, as shown in FIG. 9, a groove T can be arranged on the extension portion, the connecting ring is fixed in the groove T, and part of the connecting ring is exposed outside the groove T, so as to be connected with the connecting ring of another chain link. By using the groove to fix the connecting ring, the structure of the entire watchband can be more compact.

[0146] Returning to FIGS. 7 and 8, among the multiple chain links arranged along the width direction (such as the Y direction) of the watchband, the chain links located between the two ends can have six first connecting surfaces for fixing the connecting structure, and each first connecting surface is provided with a connecting ring; and the chain links located at the ends can have four second connecting surfaces for fixing the connecting structure, and each second connecting surface is provided with a connecting ring.

[0147] One chain link 101 in the example shown in FIG. 9 can be an integrally formed structure. In other examples, the one chain link 101 can include multiple parts which are connected by connecting members.

[0148] In the example in which the two chain links are connected by the connecting ring, the chain link 101 can also adopt the structure shown in FIGS. 10 and 11.

[0149] As shown in FIG. 11, the multiple chain links arranged along the width direction (such as the Y direction) of the watchband include multiple first chain links 1011 and multiple second chain links 1012, one second chain link 1012 is connected with two first chain links 1011, and one first chain link 1011 is connected with two second chain links 1012. The first chain links 1011 and the second chain links 1012 are arranged in a staggered manner in the length direction (such as the X direction) of the watchband.

[0150] The first link 1011 and two second links 1012 connected with the first link 1011 enclose a first accommodating cavity 1031 for accommodating the first link 1011 on one side; the second link 1012 and two first links 1011 connected with the second link 1012 enclose a second accommodating cavity 1032 for accommodating the second link 1012 on the other side.

[0151] In the examples of FIG. 10 and FIG. 11, the link 101 has a hexagonal structure.

[0152] For example, as shown in FIG. 10 and FIG. 11, among the plurality of links arranged along the width direction (e.g., Y direction) of the watchband, the links between the two ends can have six first connecting surfaces for fixing the connecting structure, and each first connecting surface is provided with a connecting ring; the links at the ends can have four second connecting surfaces for fixing the connecting structure, and each second connecting surface is provided with a connecting ring.

[0153] In the example of FIG. 11, one link 101 can be an integrally formed structure. In other examples, the one link 101 can include multiple parts connected by a connecting member.

[0154] The above examples of FIG. 9 and FIG. 11 show two different structures of the link, and the link can also have other shapes, for example, the structure of the link can have a symmetrical structure in the normal projection in the reference plane X-Y. For example, the link can be octagonal or a symmetrical special-shaped structure. In the above examples, two connecting rings are used to make the link have multiple degrees of freedom of rotation, and a structure for making the link have multiple degrees of freedom of rotation is also described below.

[0155] As shown in FIG. 12, FIG. 13 and FIG. 14, FIG. 13 is a partial structure exploded view of FIG. 12, and FIG. 14 shows a structure of a link and a connecting structure.

[0156] As shown in FIG. 12 to FIG. 14, in this example, the end of the connecting structure 102 has a first spherical surface 1023, and as shown in FIG. 14, the link 101 includes a second spherical surface 1024 matched with the first spherical surface 1023.

[0157] In this way, the first spherical surface 1023 of one of the two adjacent links can extend into the second spherical surface 1024 of the other link. The matching rotation of the first spherical surface 1023 and the second spherical surface 1024 can be referred to as a universal joint connection or a spherical pair connection.

[0158] In the example of FIG. 14, the first spherical surface 1023 at the end of the connecting structure is convex, and the second spherical surface 1024 on the chain link is concave. In other examples, the first spherical surface 1023 at the end of the connecting structure can be concave, and the second spherical surface 1024 on the chain link can be convex.

[0159] In the spherical pair rotating structure of the example of FIG. 14, the rotating shaft of the chain link 101 includes multiple axes, such as the first axis and the second axis in the X-Y plane, and more axes intersecting the first axis and the second axis.

[0160] As shown in FIG. 14, the chain link 101 can rotate around the rotating center, so that the chain link has more rotating degrees of freedom and rotates more flexibly.

[0161] As shown in FIGS. 12 and 13, in this example, the chain links arranged along the width direction of the watchband (e.g., the Y direction) are staggered.

[0162] As shown in FIG. 14, the chain link 101 can include a first extension 1A, a second extension 1B, and a third extension 1C, which are arranged at intervals along the circumference of the chain link 101. A recess S is formed between two adjacent extensions.

[0163] The connecting structure 102 is arranged on each extension, one end of the connecting structure 102 is fixedly connected with the extension, and the other end has the first spherical surface 1023.

[0164] The second spherical surface 1024 can be located in the recess S, for example, an inlay groove can be formed in the recess S, and the second spherical surface 1024 is formed on the wall surface of the inlay groove.

[0165] FIGS. 15 and 16 show another structure of the chain link. In this example, the chain link 101 has a hexagonal structure, and the chain links 101 are connected by spherical pairs, as shown in FIG. 16, the chain link 101 can rotate around the rotating center, so that the chain link has more rotating degrees of freedom and rotates more flexibly.

[0166] In the example of FIG. 16, the chain link 101 includes a first side, a second side, a third side, a fourth side, a fifth side, and a sixth side connected in sequence. The first side, the third side, and the fifth side are provided with connecting structures, one end of the connecting structure is fixedly connected with the first side, the third side, and the fifth side, and the other end of the connecting structure includes the first spherical surface 1023; the second side, the fourth side, and the sixth side are provided with inlay grooves, and the second spherical surface 1024 is formed on the wall surface of the inlay groove.

[0167] Fig. 17 and Fig. 18 show another structure of the chain link. In this example, the chain link 101 is hexagonal structure, and the chain link 101 and the chain link 101 are connected by spherical surface pair, as shown in Fig. 18, the chain link 101 can rotate around the rotation center, so that the rotation freedom of the chain link is more, and the rotation is more flexible.

[0168] As shown in Fig. 18, the chain link 101 includes a first side, a second side, a third side, a fourth side, a fifth side and a sixth side connected in sequence; each of the first side, the second side, the third side, the fourth side, the fifth side and the sixth side is provided with a connecting structure, one end of the connecting structure is fixedly connected with each side, and the other end of the connecting structure includes a first spherical surface 1023.

[0169] The chain link adjacent to the chain link shown in Fig. 18 is provided with an inlaid groove, and the inlaid groove includes a second spherical surface. In the watchband shown in the examples of Fig. 17 and Fig. 18, since each side of the chain link 101 is provided with a connecting structure, the rotation of the chain link is more flexible.

[0170] Fig. 19 and Fig. 20 show another structure of the chain link and the connecting structure, and Fig. 21 shows an exploded view of the chain link 101 and the connecting structure 102. In the watchband shown in this example, a plurality of chain links 101 are arranged along the length direction (such as X direction) of the watchband, and a plurality of chain links 101 are arranged along the width direction (such as Y direction) of the watchband. At least part of the two adjacent chain links 101 are connected by the connecting structure 102.

[0171] As shown in Fig. 21, the two ends of the connecting structure 102 respectively have spherical surfaces, such as a spherical surface 1023A and a spherical surface 1023B, one chain link has a spherical surface matched with the spherical surface 1023A, and the other chain link has a spherical surface matched with the spherical surface 1023B.

[0172] In the example of Fig. 21, the spherical surface 1023A and the spherical surface 1023B are convex, and then the spherical surface matched with the spherical surface 1023A on the chain link is concave, and the spherical surface matched with the spherical surface 1023B on the chain link is concave.

[0173] Since the chain link and the connecting structure are connected by universal joint, or understood as spherical surface pair connection, then the chain link can rotate around the rotation center, so that the rotation freedom of the chain link is more, and the rotation is more flexible.

[0174] As shown in Fig. 21, a rotating groove 1025 can be arranged on the chain link 101, and the end of the connecting structure 102 is arranged in the rotating groove 1025, and the rotating groove 1025 includes a spherical surface matched with the spherical end shape of the connecting structure 102, so that the end of the connecting structure 102 can rotate in the rotating groove 1025.

[0175] Returning to FIG. 20, in this example, two adjacent links 101 arranged along the width direction (Y direction) of the watchband are connected by the connecting structure 102, and two adjacent links 101 arranged along the length direction (X direction) of the watchband can not be connected.

[0176] In some other examples, two adjacent links 101 arranged along the width direction (Y direction) of the watchband are connected by the connecting structure 102, and two adjacent links 101 arranged along the length direction (X direction) of the watchband are connected by the connecting structure 102.

[0177] FIG. 21 shows a link 101 of an example, which includes a plurality of extensions 104 arranged at intervals along the circumference of the link. For example, as shown in FIG. 21, the link 101 includes six extensions 1041, 1042, 1043, 1044, 1045, and 1046 arranged in sequence, which can be arranged at equal intervals along the circumference of the link 101.

[0178] In some examples, as shown in FIG. 21, the extensions 1041, 1043, 1044, and 1046 can be connected to other links by the connecting structure, respectively.

[0179] In some other examples, each of the extensions of the example shown in FIG. 21 can be connected to other links by the connecting structure.

[0180] Continuing to FIG. 21, the link includes a bottom plate 1 and a cover 2, which are coupled to form the link. The bottom plate 1 and the cover 2 can be connected by a connecting member. For example, as shown in FIG. 21, a clamping column 3 can be provided on the bottom plate 1, and a clamping groove can be provided on the cover 2, the clamping column 3 being arranged in the clamping groove to connect the bottom plate 1 and the cover 2.

[0181] As shown in FIG. 21, a rotating groove 1025 for the spherical end of the connecting structure to extend into can be formed on the cover 2.

[0182] FIG. 22 is a structural schematic diagram of another watchband according to an embodiment of the present application, and FIG. 23 is an exploded view of a partial structure of the watchband according to an example of the present application. In this example, the watchband includes a plurality of links 101, such as a plurality of links 101 arranged along the width direction (e.g., the Y direction) of the watchband.

[0183] The plurality of links arranged along the width direction of the watchband includes a plurality of first links 1011 and a plurality of second links 1012, wherein one second link 1012 is connected to two first links 1011, and one first link 1011 is connected to two second links 1012.

[0184] For example, in FIG. 23, three link assemblies are shown, link assembly A, link assembly B and link assembly C, which are arranged in sequence along the length direction (e.g., X direction) of the watchband. Each link assembly includes a plurality of first links 1011 and a plurality of second links 1012. One second link 1012 is connected to two first links 1011, and one first link 1011 is connected to two second links 1012.

[0185] The first links 1011 and the second links 1012 are arranged in staggered manner along the length direction (e.g., X direction) of the watchband.

[0186] The first links 1011 and the second links 1012 are arranged in staggered manner along the length direction of the watchband. For example, as shown in FIG. 23, the first link 1011 protrudes towards the first side compared to the two second links 1012 adjacent to it, and the second link 1012 protrudes towards the second side compared to the two first links 1011 adjacent to it. The first side is parallel to the length direction (e.g., X direction) of the watchband.

[0187] As shown in FIG. 23, the first link 1011 and the two second links 1012 connected to the first link 1011 enclose a first accommodating cavity 1031 for accommodating the first link 1011 on one side (e.g., the first side in FIG. 23). The second link 1012 and the two first links 1011 connected to the second link 1012 enclose a second accommodating cavity 1032 for accommodating the second link 1012 on the other side (e.g., the second side in FIG. 23).

[0188] Continuing to FIGS. 22 and 23, the watchband further includes a plurality of first connecting shafts 105 and a plurality of second connecting shafts 106. The first connecting shaft 105 connects two first links 1011 and a second link 1012 located in the second accommodating cavity 1032. The second connecting shaft 106 connects two second links 1012 and a first link 1011 located in the first accommodating cavity 1031. In this way, adjacent links along the length direction of the watchband can be connected together.

[0189] In the example of FIGS. 22 and 23, adjacent first links 1011 and second links 1012 are fixedly connected in the width direction of the watchband, as shown in FIG. 24. For example, a plurality of first links 1011 and a plurality of second links 1012 in the width direction of the watchband in FIG. 24 are fixedly connected together.

[0190] The watchband of the example of FIGS. 22 and 23 has a plurality of links arranged in staggered manner, which can improve the softness of the entire watchband, improve the wearing comfort of the watchband, and improve the user experience.

[0191] The first link 1011 and the second link 1012 adjacent to each other have multiple fixed connection modes. For example, in FIG. 24, a groove 107 is formed at the connection between the first link 1011 and the second link 1012, and the groove 107 does not penetrate the connection between the two links.

[0192] For example, the watchband has opposite first and second surfaces, the first surface can be the surface away from the skin, and the second surface can be the surface close to the skin. The groove 107 can be recessed from the first surface to the second surface, and there is a gap between the bottom surface of the groove 107 and the second surface, that is, the groove does not penetrate to the second surface. In this way, the first link 1011 and the second link 1012 adjacent to each other are fixedly connected together.

[0193] When the user wears the watchband of FIG. 23, the multiple links visible to the user are arranged in an array, which can improve the appearance of the watchband.

[0194] In order to improve the wearing comfort of the watchband, as shown in FIG. 25, which shows the structure of the side of the watchband close to the skin, the second surface of the watchband close to the skin is a flat surface.

[0195] In the watchbands of FIGS. 23 and 24, in order to prevent the links from moving along the axial direction of the connection shaft, a fixed shaft can also be included, which is arranged at the end of the connection shaft. For example, in FIG. 23, fixed shafts 108A, 108B, 108C and 108D are included, the fixed shafts 108A and 108B are arranged at the two ends of the first connection shaft 105, and the fixed shafts 108C and 108D are arranged at the two ends of the second connection shaft 106.

[0196] That is, by using the fixed shaft at the end of the connection shaft, the displacement of the connection shaft in the axial direction thereof can be limited, and the connection shaft is prevented from moving in the axial direction thereof, which improves the use performance of the watchband.

[0197] In order to ensure that the link 101 at the end can rotate around the connection shaft and is prevented from moving along the connection shaft, in some examples, as shown in FIG. 22, the first connection shaft 105 can be extended into the link 101 at the end. The fixed shaft 108A is fixedly connected with the other part of the link 101 at the end.

[0198] In some structures, as shown in FIG. 22, the ends of the fixed shaft and the connection shaft can have a gap or can be in contact.

[0199] In some examples, as shown in FIG. 24, one link 101 can be a one-piece structure. In other examples, one link 101 can include multiple structural members connected by a connecting member, for example, can include a bottom plate and a cover, the bottom plate and the cover are buckled and connected by a clamping structure.

[0200] Figure 26 is another table belt structure according to an embodiment of the present application. The plurality of links arranged along the width direction of the table belt includes a plurality of first links 1011 and a plurality of second links 1012, wherein one second link 1012 is connected with two first links 1011, and one first link 1011 is connected with two second links 1012.

[0201] The first links 1011 and the second links 1012 are arranged in a staggered manner along the length direction (e.g. X direction) of the table belt.

[0202] The first link 1011 and the two second links 1012 connected with the first link 1011 enclose a first accommodating cavity 1031 for accommodating the first link 1011 on one side; and the second link 1012 and the two first links 1011 connected with the second link 1012 enclose a second accommodating cavity 1032 for accommodating the second link 1012 on the other side.

[0203] In the implementation structure, the adjacent first link 1011 and the second link 1012 are separated, i.e. the first link 1011 and the second link 1012 are two independent structural members.

[0204] As shown in Figure 27, in addition to the first connecting shaft 105 and the second connecting shaft 106, a third connecting shaft 109 is also included. The third connecting shaft 109 can be parallel to the first connecting shaft 105, and the third connecting shaft 109 can extend along the width direction of the table belt. The third connecting shaft 109 connects the adjacent first link 1011 and the second link 1012.

[0205] In the example of Figure 27, in order to prevent the link from moving along the axial direction of the connecting shaft, a limiting structure is also included in the example, which can prevent the link from moving along the axial direction of the connecting shaft during rotation.

[0206] Figures 27 and 28 exemplarily show a limiting structure. For example, a limiting column 110A can be arranged in the link 101, and a limiting groove 110B can be arranged on the first connecting shaft 105. Since the link 101 needs to rotate relative to the first connecting shaft 105, the limiting groove 110B can be arranged along the circumferential direction of the first connecting shaft 105, and the limiting column 110A is located in the limiting groove 110B. The limiting column 110A and the limiting groove 110B are matched to limit the link 101, so as to prevent the link from rotating along the axial direction of the connecting shaft when the link rotates relative to the connecting shaft.

[0207] In the example shown in FIGS. 28 and 29, the first link 1011 is configured to allow the first connecting shaft 105 and the third connecting shaft 109 to pass therethrough, and the second link 1012 is configured to allow the second connecting shaft 106 and the third connecting shaft 109 to pass therethrough. In the example shown in FIG. 29, the first link 1011 can be provided with a first rotation slot 111A configured to allow the first connecting shaft 105 to rotate therein, and a third rotation slot 111C configured to allow the third connecting shaft 109 to rotate therein.

[0208] In addition to preventing the first link 1011 from moving along the axial direction of the first connecting shaft 105, it is also necessary to prevent the first link 1011 from moving along the axial direction of the third connecting shaft 106, and to simplify the structure, the limiting post 110A can be arranged between the first rotation slot 111A and the third rotation slot 111C, as shown in FIG. 29.

[0209] As shown in FIG. 29, the second link 1012 can be provided with a second rotation slot 111B configured to allow the second connecting shaft 106 to rotate therein, and a third rotation slot 111C configured to allow the third connecting shaft 109 to rotate therein.

[0210] In some examples, one link 101 can be a one-piece structure. In other examples, one link 101 can include a plurality of structural components connected by a connecting component. For example, as shown in FIG. 30, one link 101 can include a base plate 1 and a cover 2, and the base plate 1 and the cover 2 can be coupled together and connected by a clamping structure.

[0211] In this example, the limiting post 110A is arranged on the base plate 1, and a clamping slot 201 can be formed in the cover 2, and the limiting post 110A is arranged in the clamping slot 201 to connect the base plate 1 and the cover 2. The limiting post 110A not only has a limiting function, but also has a connecting function, which can simplify the structure of the watchband.

[0212] FIG. 31 shows another example of a watchband structure according to an embodiment of the present application. The plurality of links arranged along the width direction of the watchband include a plurality of first links 1011 and a plurality of second links 1012, wherein one second link 1012 is connected to two first links 1011, and one first link 1011 is connected to two second links 1012.

[0213] The first links 1011 and the second links 1012 are arranged in a staggered manner along the length direction (e.g., the X direction) of the watchband.

[0214] A first link 1011 and two second links 1012 connected to the first link 1011 form a first receiving cavity 1031, which is used to receive the first link 1011 located on one side; a second link 1012 and two first links 1011 connected to the second link 1012 form a second receiving cavity 1032, which is used to receive the second link 1012 located on the other side.

[0215] In this structure, the adjacent first link 1011 and second link 1012 are separated, that is, the first link 1011 and the second link 1012 are two independent structural components.

[0216] As shown in Figure 32, the strap includes not only the first connecting shaft 105 and the second connecting shaft 106, but also a third connecting shaft 109. The third connecting shaft 109 may be parallel to the first connecting shaft 105 and may extend along the width direction of the strap. The third connecting shaft 109 connects adjacent first links 1011 and second links 1012.

[0217] The first connecting shaft 105, the second connecting shaft 106, or the third connecting shaft 109 may include, as shown in Figure 32, an inner shaft 112A, with outer shafts 112B sleeved at both ends of the inner shaft 112A; among the multiple links arranged along the width direction of the watch strap, the links located at the ends are rotatably connected to the outer shaft, the links located between the two ends are rotatably connected to the inner shaft, and the outer shaft located at the ends has a limiting function.

[0218] Figure 33 shows another watch strap structure according to an embodiment of this application. The multiple links arranged along the width direction of the watch strap include: multiple first links 1011 and multiple second links 1012, wherein one second link 1012 is connected to two first links 1011, and one first link 1011 is connected to two second links 1012.

[0219] The first link 1011 and the second link 1012 are staggered along the length of the strap (e.g., the X direction).

[0220] A first link 1011 and two second links 1012 connected to the first link 1011 form a first receiving cavity, which is used to receive the first link 1011 located on one side; a second link 1012 and two first links 1011 connected to the second link 1012 form a second receiving cavity, which is used to receive the second link 1012 located on the other side.

[0221] As shown in the example of FIG. 33, the adjacent first links 1011 and second links 1012 arranged along the width direction of the watchband are fixedly connected. For example, a groove can be formed at the connection between the first link 1011 and the second link 1012, and the groove does not penetrate through the opposite two surfaces in the thickness direction of the watchband. The groove can improve the aesthetic appearance of the watchband.

[0222] In the example of FIG. 33, the first connecting shaft 105 connects two first links 1011 and a second link 1012 located in the second accommodating cavity 1032, and the second connecting shaft 106 connects two second links 1012 and a first link 1011 located in the first accommodating cavity 1031. In this way, the adjacent links along the length direction of the watchband can be connected together.

[0223] FIG. 34 shows the structure of the first connecting shaft 105 or the second connecting shaft 106, which can include a plurality of disconnected shaft segments, such as the first shaft segment 113A and the second shaft segment 113B.

[0224] As shown in FIG. 34, along the axial direction of the first shaft segment 113A and the second shaft segment 113B, the first shaft segment 113A and the second shaft segment 113B each include a first portion 1041 and a second portion 1042, and the radial dimension of the first portion 1041 is greater than that of the second portion 1042.

[0225] The part of the link 101 at the end in the width direction of the watchband is fixedly connected with the first portion 1041, and the link 101 between the two ends in the width direction of the watchband is rotatably connected with the second portion 1042.

[0226] That is, by using the first portion 1041 with a larger radial dimension at the end of the connecting shaft to be fixedly connected with the link, the displacement of other connections along the axial direction of the second portion 1042 can be limited, and the connecting shaft can be prevented from moving in the axial direction, thereby improving the use performance of the watchband.

[0227] In order to ensure that the link 101 at the end can rotate around the connecting shaft and avoid the movement of the connecting shaft, in some examples, the second portion 1042 can be extended into the link 101 at the end. The first portion 1041 is fixedly connected with the other part of the link 101 at the end.

[0228] With the connecting shaft structure of FIG. 34, when assembling, the first shaft segment 113A can be inserted into the mounting holes of the remaining links from the hole for mounting the connecting shaft on the link at the end, and then the first part 1041 is fixed on the link at the end. Similarly, the second shaft segment 113B can be inserted into the mounting holes of the remaining links from the hole for mounting the connecting shaft on the link at the other end, and then the first part 1041 is fixed on the link at the other end. Such a connecting shaft not only has a simple structure, but also is easy to assemble.

[0229] In the above examples, the links are connected by connecting shafts, the links can rotate around the axis of the connecting shaft, improve the softness of the watchband, improve the wearing comfort, and the multiple links are arranged in a staggered manner, which can also improve the appearance of the entire watchband.

[0230] In some examples, the links can have a symmetrical structure, for example, the links can only have a symmetrical structure in the reference plane X-Y plane.

[0231] Alternatively, the links can have a hexagonal structure. Alternatively, the links can include multiple extensions, and the multiple extensions can be arranged at intervals along the circumference of the link, for example, the multiple extensions are arranged at equal intervals along the circumference of the link.

[0232] In the above examples, the watchband including the first connecting shaft, the second connecting shaft and the third connecting shaft, the softness is further improved, and the wearing comfort is further improved.

[0233] In the watchbands of FIGS. 22, 26, 31 and 33 of the examples of the present application, different structures of connecting shafts are shown. In some examples, all the connecting shaft structures in the watchband can be the same. For example, in some watchbands, the connecting shafts can all adopt the structure shown in FIG. 33.

[0234] In some other watchbands, the connecting shaft structures in the watchband can not be the same, for example, some connecting shafts adopt the structure shown in FIG. 33, and some other connecting shafts adopt the structure shown in FIG. 22, or some connecting shafts adopt the structure shown in FIG. 26, and some other connecting shafts adopt the structure shown in FIG. 31.

[0235] In the watchbands of the examples of the present application, the shapes of the links can be the same. For example, all the links have the same shape, all the links have the hexagonal structure of the above examples, or all the links have the structure including multiple extensions of the above examples.

[0236] In some other watchbands, the shapes of the links can be different. For example, some links have the hexagonal structure of the above examples, and some other links have the structure including multiple extensions of the above examples.

[0237] For example, along the width direction of the watchband, the shapes of the links at the two ends can be the same, and the shapes of the links in the middle between the two ends can be the same. For another example, along the width direction of the watchband, the shapes of two adjacent links can be the same, and along the length direction of the watchband, the shapes of two adjacent links can be different.

[0238] In the watchband of the present application, two adjacent links 101 can be connected by a universal joint structure, for example, connected by the connecting ring of the above example, or connected by the spherical pair of the above example. Two adjacent links 101 can also be connected by a connecting shaft, for example, connected by the first connecting shaft and the second connecting shaft shown in FIGS. 23-34.

[0239] In some watchbands, the connections between some links can be connected by a universal joint structure, and the connections between other links can be connected by a connecting shaft. For example, along the length direction of the watchband, the links at the two ends are connected by a connecting shaft, and the links in the middle between the two ends are connected by a universal joint structure. For another example, along the length direction of the watchband, the links at the two ends are connected by a universal joint structure, and the links in the middle between the two ends are connected by a connecting shaft. For yet another example, along the length direction of the watchband, the connecting shaft connection structure and the universal joint connection structure are arranged alternately.

[0240] In some watchbands, for example, not only including a connecting shaft connection structure, but also including a universal joint connection structure, the shape of the link connected by the connecting shaft can be different from the shape of the link connected by the universal joint. For example, the shape of the link connected by the connecting shaft is a hexagon, and the shape of the link connected by the universal joint is the structure of the above example including a plurality of extensions.

[0241] In the description of the present application, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0242] The above description is merely specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
