Description

watch straps and watches Technical Field

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

[0002] Currently, most wearable electronic devices on the market integrate heart rate and blood oxygen detection functions. Taking smart wearable watches as an example, the watch face is equipped with a heart rate sensor. When a user wears a smart wearable watch, the heart rate sensor, in close contact with the user's skin, can monitor the user's heart rate. However, in related technologies, the watch band of smart wearable watches is usually a single-layer structure made of a single material. However, when the material used for the watch band is high in hardness, its ductility is low. If the user wears the watch band tightly so that the heart rate sensor on the watch face is in close contact with the user's skin, the watch band feels hard and heavy, resulting in poor wearing comfort. When the material used for the watch band is low in hardness, its ductility is high. If the user wears the watch band tightly so that the heart rate sensor on the watch face is in close contact with the user's skin, the watch band can easily constrict the user's wrist or arm, hindering blood circulation and affecting wearing comfort.

[0003] Summary of the Invention

[0004] This application provides a watch strap and a watch, which aims to achieve a balance between softness / hardness and elasticity in the watch strap, thereby improving the user's wearing comfort.

[0005] In a first aspect, embodiments of this application provide a watch strap, including:

[0006] A first soft layer and a second soft layer are provided together.

[0007] An interlayer is disposed between the first soft layer and the second soft layer;

[0008] The elongation of the interlayer is less than that of the first soft layer and the second soft layer.

[0009] Secondly, embodiments of this application also provide a watch, including a dial and a strap as described in the first aspect, the strap being connected to the dial.

[0010] This application provides a watch strap and a watch, in which a first soft layer and a second soft layer are bonded together. The first and second soft layers are relatively soft. When a user wears the watch, the user's skin can contact the first and / or second soft layers. By setting a sandwich between the first and second soft layers, the first and second soft layers are connected to the sandwich, and the extensibility of the sandwich is less than that of the first and second soft layers. This allows the sandwich to have an anti-extensibility effect on the first and second soft layers, improving their anti-extensibility. Consequently, the watch strap as a whole has a certain degree of anti-extensibility. The watch strap achieves a balance between softness and hardness and extensibility. Therefore, when the watch strap is applied to a watch, the user can wear the watch stably, allowing the watch face to fit snugly against the user's skin. The watch strap provides a soft feel to the user, and it does not constrict the user's wrist or arm excessively, thus improving the user's wearing comfort. Attached Figure Description

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0021] It should be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0022] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] Referring to Figures 1 and 2, this application embodiment provides a watch strap. The watch strap includes a first soft layer 10, a second soft layer 20, and an interlayer 30. The first soft layer 10 and the second soft layer 20 are bonded together, and the interlayer 30 is disposed between the first soft layer 10 and the second soft layer 20. The elongation of the interlayer 30 is less than the elongation of the first soft layer 10 and the second soft layer 20.

[0024] In this embodiment, the first soft layer 10 and the second soft layer 20 of the watch strap are relatively soft, so that when the user wears the watch, the user's skin can come into contact with the first soft layer 10 and / or the second soft layer 20. The first soft layer 10 and the second soft layer 20 are bonded together. A sandwich layer 30 is provided between the first soft layer 10 and the second soft layer 20. The first soft layer 10 and the second soft layer 20 are connected to the sandwich layer 30. By making the extensibility of the sandwich layer 30 less than that of the first soft layer 10 and the second soft layer 20, the sandwich layer 30 has an anti-extensibility effect on the first soft layer 10 and the second soft layer 20. The sandwich layer 30 can improve the anti-extensibility of the first soft layer 10 and the second soft layer 20, so that the watch strap as a whole has a certain degree of anti-extensibility. This helps to achieve a balance between softness and hardness and extensibility in the watch strap. As a result, when the watch strap is applied to a watch, the user can wear the watch stably, so that the watch face can be stably and tightly attached to the user's skin. The watch strap provides a relatively soft feel to the user, and at the same time, the watch strap will not be too tight on the user's wrist or arm, which helps to improve the user's wearing comfort.

[0025] For example, the first soft layer 10 and the second soft layer 20 can be prepared from at least one of the following materials: silicone, rubber, fluororubber, hydrogenated nitrile rubber (HNBR), and thermoplastic polyurethane (TPU).

[0026] Understandably, the interlayer 30 is located between the first soft layer 10 and the second soft layer 20. The first soft layer 10, the second soft layer 20 and the interlayer 30 are flexible, allowing the watch strap to bend and be worn on the user's wrist or arm.

[0027] For example, the first soft layer 10 and the second soft layer 20 are sequentially arranged along a first direction. The thickness direction of the watch strap can be the first direction, or the thickness direction of the watch strap can be the Z direction as shown in Figure 2. The interlayer 30 is disposed between the first soft layer 10 and the second soft layer 20. The first soft layer 10 and the second soft layer 20 are located at the outermost edge of the watch strap along its thickness direction. When the user wears the watch, one side of the watch strap along its thickness direction contacts the skin of the user's wrist or arm, that is, the user's skin can contact the first soft layer 10 or the second soft layer 20.

[0028] In some embodiments, the first soft layer 10 and / or the second soft layer 20 are snapped into the interlayer 30. It is understood that snapping the first soft layer 10 into the interlayer 30 establishes a connection between the first soft layer 10 and the interlayer 30, improving the connection strength between the first soft layer 10 and the interlayer 30, and enhancing the anti-stretching effect of the interlayer 30 on the first soft layer 10. Similarly, snapping the second soft layer 20 into the interlayer 30 establishes a connection between the second soft layer 20 and the interlayer 30, improving the connection strength between the second soft layer 20 and the interlayer 30, enhancing the anti-stretching effect of the interlayer 30 on the second soft layer 20, and improving the overall anti-stretching properties of the watch strap.

[0029] In some embodiments, the first soft layer 10 and / or the second soft layer 20 are provided with grooves, and the interlayer 30 is provided with protrusions. The protrusions are engaged with the grooves to achieve the engagement between the first soft layer 10 and the interlayer 30, and / or the engagement between the second soft layer 20 and the interlayer 30.

[0030] For example, a first soft layer 10 and a second soft layer 20 are sequentially disposed along a first direction, and an interlayer 30 is disposed between the first soft layer 10 and the second soft layer 20. Along the first direction, the first soft layer 10 and the second soft layer 20 are each provided with a groove on the side near the interlayer 30, and the interlayer 30 is provided with protrusions on opposite sides. The protrusion on one side of the interlayer 30 engages with the groove of the first soft layer 10, and the protrusion on the other side of the interlayer 30 engages with the groove of the second soft layer 20, thereby realizing the engagement between the first soft layer 10 and the interlayer 30, as well as the engagement between the second soft layer 20 and the interlayer 30.

[0031] In some embodiments, as shown in Figures 1 and 2, the interlayer 30 has a mesh structure, and the first soft layer 10 is at least partially inserted through the perforated portion 31 of the interlayer 30 and connected to the second soft layer 20. It is understood that the first soft layer 10 and the second soft layer 20 are arranged sequentially along a first direction, the interlayer 30 has a mesh structure, the interlayer 30 has multiple perforated portions 31, and the perforated portions 31 of the interlayer 30 can penetrate opposite sides of the interlayer 30 along the first direction. The first soft layer 10 can be inserted through the perforated portion 31 of the interlayer 30 and extend into the second soft layer 20 to connect with the second soft layer 20. By having the first soft layer 10 at least partially pass through the hollow portion 31 of the interlayer 30 and connect with the second soft layer 20, the interlayer 30 can abut against the portion of the first soft layer 10 that passes through its hollow portion 31, thereby limiting the extension of the first soft layer 10 and the second soft layer 20, achieving the anti-extension effect of the interlayer 30 on the first soft layer 10 and the second soft layer 20, and improving the overall anti-extension performance of the watch strap.

[0032] For example, the first soft layer 10 and the second soft layer 20 are both inserted through the hollow portion 31 of the interlayer 30, and the portions of the first soft layer 10 and the second soft layer 20 inserted through the hollow portion 31 are interconnected.

[0033] Furthermore, the first soft layer 10 passes through the hollow portion 31 of the interlayer 30 and can fill the hollow portion 31 of the interlayer 30; or, both the first soft layer 10 and the second soft layer 20 pass through the hollow portion 31 of the interlayer 30, and the first soft layer 10 and the second soft layer 20 can fill the hollow portion 31 of the interlayer 30, so as to fully improve the anti-stretching effect of the interlayer 30 on the first soft layer 10 and the second soft layer 20.

[0034] In some embodiments, the interlayer 30 and the first soft layer 10 are bonded together, and the interlayer 30 and the second soft layer 20 are bonded together. By bonding, the interlayer 30 is connected to the first soft layer 10 and the second soft layer 20. The interlayer 30 can act on the first soft layer 10 and the bonded position therewith, as well as the second soft layer 20 and the bonded position therewith, to restrict the stretching of the first soft layer 10 and the second soft layer 20, thereby achieving an anti-stretching effect on the first soft layer 10 and the second soft layer 20 and improving the overall anti-stretching properties of the watch strap.

[0035] In some embodiments, as shown in Figures 2 and 3, the first soft layer 10 and / or the second soft layer 20 are provided with receiving grooves 11, and the interlayer 30 is disposed in the receiving grooves 11 so that the first soft layer 10 and the second soft layer 20 wrap the interlayer 30. The interlayer 30 is disposed within the receiving grooves 11 of the first soft layer 10 and / or the second soft layer 20 so that the first soft layer 10 and the second soft layer 20 can wrap the interlayer 30, preventing the interlayer 30 from being exposed, avoiding the interlayer 30 from being affected by external forces, ensuring the connection stability of the first soft layer 10 and the second soft layer 20 to the interlayer 30, and also improving the aesthetics of the watch strap.

[0036] For example, as shown in Figure 4, the interlayer 30 is an annular interlayer with a clearance hole 32 in the middle. The first soft layer 10 may have an annular receiving groove 11. The interlayer 30 is disposed in the receiving groove 11. The first soft layer 10 extends from the outer periphery of the interlayer 30 along a first direction to connect with the second soft layer 20 to wrap the outer ring of the interlayer 30. It also passes through the clearance hole 32 of the interlayer 30 and extends along the first direction to connect with the second soft layer 20 to wrap the inner ring of the interlayer 30. The second soft layer 20 covers the opening of the receiving groove 11, so that the first soft layer 10 and the second soft layer 20 completely wrap the interlayer 30 to prevent the interlayer 30 from being exposed.

[0037] For example, the interlayer 30 may also include multiple spaced sub-parts, and the first soft layer 10 and / or the second soft layer 20 may be provided with multiple spaced receiving grooves 11, and the multiple sub-parts may be provided in the multiple receiving grooves 11.

[0038] Specifically, the first soft layer 10 and / or the second soft layer 20 are provided with receiving grooves 11, and the interlayer 30 is disposed in the receiving grooves 11. The interlayer 30 is tightly attached to the first soft layer 10 and the second soft layer 20 on opposite sides along the first direction, thereby improving the connection stability between the interlayer 30 and the first soft layer 10, as well as the connection stability between the interlayer 30 and the second soft layer 20.

[0039] For example, as shown in FIG3, the first soft layer 10 is provided with a receiving groove 11. Along the direction perpendicular to the first direction, the distance D1 between the side wall of the receiving groove 11 and the outer peripheral surface of the first soft layer 10 is greater than 2.5mm, so as to ensure the connection stability between the first soft layer 10 and the second soft layer 20, and to ensure that the first soft layer 10 and the second soft layer 20 can stably wrap the interlayer 30. For example, the distance D1 between the side wall of the receiving groove 11 and the outer peripheral surface of the first soft layer 10 can be 2.5mm, 2.8mm, 3.2mm or 3.5mm, etc.

[0040] In some embodiments, as shown in FIG2, the first soft layer 10 and the second soft layer 20 are integrally formed to ensure the connection stability between the first soft layer 10 and the second soft layer 20, while preventing the interlayer 30 from detaching from the first soft layer 10 and the second soft layer 20, thereby improving the overall connection stability of the watch strap.

[0041] In some embodiments, the watch strap can be prepared by the following method: a semi-solid first soft layer 10 and a second soft layer 20 are separately molded; an interlayer 30 is placed between the semi-solid first soft layer 10 and the second soft layer 20; then, the semi-solid first soft layer 10 and the second soft layer 20 are cured, causing them to fuse together and form an integral solid structure, thus achieving an integrated arrangement between the first soft layer 10 and the second soft layer 20. Furthermore, curing the semi-solid first soft layer 10 and the second soft layer 20 also allows the first soft layer 10 and the interlayer 30 to be bonded together, and the second soft layer 20 and the interlayer 30 to be bonded together, so that the interlayer 30 connects to the first soft layer 10 and the second soft layer 20. The interlayer 30 can act on the bonded locations of the first soft layer 10 and the second soft layer 20, restricting the extension of the first soft layer 10 and the second soft layer 20.

[0042] Furthermore, after the first soft layer 10 and the second soft layer 20 are separately formed into semi-solid state, an installation groove can be formed on the first soft layer 10 using a positioning tool, and the interlayer 30 is placed in the installation groove. During the curing process, the first soft layer 10 and the second soft layer 20 fuse together and fill the gap between the groove wall of the installation groove and the interlayer 30, so that the first soft layer 10 forms a receiving groove 11 that matches the interlayer 30, and the cured first soft layer 10 and the second soft layer 20 wrap around the interlayer 30 to prevent the interlayer 30 from being exposed.

[0043] Furthermore, the interlayer 30 has a mesh structure and multiple perforated portions 31. By performing a curing treatment on the semi-solid first soft layer 10 and the second soft layer 20, the semi-solid first soft layer 10 and the second soft layer 20 can extend into the perforated portions 31 of the interlayer 30 and fuse with each other to form an integral solid structure. That is, the first soft layer 10 and the second soft layer 20 can pass through the perforated portions 31 of the interlayer 30 and connect with each other, improving the connection stability between the first soft layer 10, the second soft layer 20 and the interlayer 30. At the same time, the interlayer 30 can abut against the portion of the first soft layer 10 that passes through its perforated portions 31, further restricting the extension of the first soft layer 10 and the second soft layer 20.

[0044] In some embodiments, the thickness of the first soft layer 10 and the second soft layer 20 along the first direction are greater than or equal to 0.6 mm, so that the first soft layer 10 and the second soft layer 20 can better resist impacts and wear during daily use. Furthermore, the thickness of the first soft layer 10 and the second soft layer 20 after curing is greater than or equal to 0.6 mm, which can prevent the first soft layer 10 and the second soft layer 20 from being too thin, causing the interlayer 30 to penetrate through the first soft layer 10 or the second soft layer 20. For example, along the first direction, the minimum thickness H1 of the first soft layer 10 can be 0.6 mm, 0.65 mm, or 0.72 mm, etc., and the minimum thickness H2 of the second soft layer 20 can be 0.6 mm, 0.65 mm, or 0.72 mm, etc.

[0045] For example, as shown in FIG3, the first soft layer 10 is provided with a receiving groove 11. The distance from the bottom surface of the receiving groove 11 to the side of the first soft layer 10 away from the second soft layer 20 is the minimum thickness H1 of the first soft layer 10 along the first direction, and the minimum thickness H1 is greater than or equal to 0.6 mm.

[0046] In some embodiments, the first soft layer 10 and the second soft layer 20 are made of the same material, which makes the first soft layer 10 and the second soft layer 20 have good compatibility and helps to improve the connection stability of the first soft layer 10 and the second soft layer 20.

[0047] In some embodiments, the elongation of the interlayer 30 is greater than or equal to 0. It is understood that the elongation of the interlayer 30 can be 0, indicating no elongation; or the elongation of the interlayer 30 can be greater than 0, indicating a certain degree of elongation. By adjusting the elongation of the interlayer 30, the degree of resistance to stretching exerted by the interlayer 30 on the first soft layer 10 and the second soft layer 20 can be changed, so that the overall elongation of the watchband meets the required requirements.

[0048] For example, along the second direction, the elongation of the interlayer 30 is greater than or equal to 0, less than the elongation of the first soft layer 10, and less than the elongation of the second soft layer 20. The second direction is perpendicular to the first direction.

[0049] For example, the length direction of the watch strap can be a second direction, as shown by the Y direction in Figure 1. When the watch strap is applied to a watch, one end of the strap along its length can be connected to the watch face, and the other end can be wrapped around the user's wrist or arm to improve the user's wearing comfort.

[0050] In some embodiments, as shown in Figures 4 and 5, the interlayer 30 is a mesh structure. It is understood that the mesh structure can withstand a certain tensile force, and the mesh structure of the interlayer 30 is beneficial for enhancing its resistance to stretching, making the elongation rate of the interlayer 30 less than that of the first soft layer 10 and the second soft layer 20.

[0051] For example, the interlayer 30 may be a mesh structure made of materials such as nylon, polyester, or glass fiber.

[0052] For example, the interlayer 30 with a mesh structure can be prepared by weaving wires, or the interlayer 30 with a mesh structure can be prepared by cutting on a sheet structure.

[0053] In some embodiments, as shown in Figures 4 and 5, the multiple hollow portions 31 of the interlayer 30 are evenly spaced. It is understood that the evenly spaced arrangement of the multiple hollow portions 31 of the interlayer 30 helps to ensure that the interlayer 30 is evenly connected to the first soft layer 10 and to the second soft layer 20, thereby balancing the anti-stretching effect of the interlayer 30 on the first soft layer 10 and the second soft layer 20, resulting in relatively consistent anti-stretching properties throughout the watchband and improving the overall wearing comfort. Furthermore, the evenly spaced arrangement of the hollow portions 31 can better disperse the force exerted on the interlayer 30 when the first soft layer 10 and the second soft layer 20 stretch, preventing excessive deformation of the interlayer 30 and ensuring the structural stability and reliability of the interlayer 30.

[0054] For example, the multiple perforations 31 of the interlayer 30 are evenly spaced, and the first soft layer 10 can be evenly inserted through the multiple perforations 31 of the interlayer 30, so that the force transmitted by the interlayer 30 to the first soft layer 10 and the second soft layer 20 through the portion of the first soft layer 10 inserted through the perforations 31 is relatively uniform, thus balancing the anti-stretching effect of the interlayer 30 on the first soft layer 10 and the second soft layer 20.

[0055] For example, the multiple hollow portions 31 of the interlayer 30 are evenly spaced. When the interlayer 30 is bonded to the first soft layer 10, the bonding positions between the interlayer 30 and the first soft layer 10 are relatively evenly distributed, thus balancing the anti-stretching effect of the interlayer 30 on the first soft layer 10 and the second soft layer 20.

[0056] For example, the cutout portion 31 of the interlayer 30 can also be circular, triangular, quadrilateral or hexagonal, etc.

[0057] For example, the multiple cutouts 31 of the interlayer 30 have the same shape.

[0058] In some embodiments, as shown in Figures 4 and 5, the interlayer 30 includes a plurality of first traces 33 and a plurality of second traces 34. The plurality of first traces 33 and the plurality of second traces 34 are arranged intersectingly so that a cutout portion 31 is formed between two adjacent first traces 33 and two adjacent second traces 34. It can be understood that the plurality of first traces 33 are arranged alternately, the plurality of second traces 34 are arranged alternately, and the plurality of first traces 33 and the plurality of second traces 34 are arranged intersectingly, so that the cutout portion 31 can be a quadrilateral formed by two adjacent first traces 33 and two adjacent second traces 34. The interlayer 30 is formed by the cross arrangement of multiple first threads 33 and multiple second threads 34. The arrangement of the first threads 33 and the second threads 34 is relatively regular. The interlayer 30 can be woven by multiple first threads 33 and multiple second threads 34, which helps to simplify the manufacturing process of the interlayer 30. Moreover, the weaving method is more conducive to obtaining a high-density interlayer 30, enhancing the stretch resistance of the interlayer 30, and achieving a balance between the softness and hardness and stretch of the watch strap.

[0059] For example, multiple first traces 33 extend in the same direction, and multiple second traces 34 extend in the same direction.

[0060] In one optional embodiment, as shown in FIG4, the extension directions of the plurality of first traces 33 are set at an angle to the length direction of the watch strap, and the extension directions of the plurality of second traces 34 are also set at an angle to the length direction of the watch strap. It is understood that the extension directions of both the plurality of first traces 33 and the plurality of second traces 34 are set at an angle to the length direction of the watch strap, allowing the first traces 33 and second traces 34 to extend along the length direction of the watch strap, and the elongation rate of the interlayer 30 along the length direction of the watch strap is greater than 0. By adjusting the angle between the extension directions of the first traces 33 and second traces 34 and the length direction of the watch strap, the elongation rate of the interlayer 30 along the length direction of the watch strap can be changed, thus limiting the elongation rate of the first soft layer 10 and the second soft layer 20 along the length direction of the watch strap, and adjusting the elongation rate of the watch strap along its length direction.

[0061] Specifically, the angle a1 between the multiple first traces 33 and the length direction of the watch strap, and the angle a2 between the multiple second traces 34 and the length direction of the watch strap, can be adjusted according to the actual situation and are not limited here.

[0062] For example, the angle a1 between the extension direction of the plurality of first traces 33 and the length direction of the watch strap is equal to the angle a2 between the extension direction of the plurality of second traces 34 and the length direction of the watch strap.

[0063] In another alternative embodiment, as shown in FIG5, a plurality of first traces 33 extend along the length direction of the watch strap. It is understood that the plurality of first traces 33 extend along the length direction of the watch strap, so that the first traces 33 cannot be extended in the length direction of the watch strap, and the elongation rate of the interlayer 30 in the length direction of the watch strap is 0.

[0064] For example, the length direction of the watch strap can be shown as the Y direction in Figure 5, and the width direction of the watch strap can be shown as the X direction in Figure 5.

[0065] Specifically, the extension direction of the plurality of second traces 34 may be inclined relative to the length direction of the watch strap, or the plurality of second traces 34 may extend along the width direction of the watch strap.

[0066] In some embodiments, as shown in FIG4, the mezzanine 30 further includes an edge line 35, which is located at the edge of a plurality of first traces 33 and a plurality of second traces 34. The edge line 35 can connect the plurality of first traces 33 and / or the plurality of second traces 34 to improve the overall connection stability of the mezzanine 30.

[0067] For example, multiple first traces 33 and multiple second traces 34 can be woven together with the edge lines to form the interlayer 30.

[0068] For example, as shown in FIG4, a plurality of first wirings 33 and a plurality of second wirings 34 are distributed in an annular area. The watch strap includes two edge lines 35, one edge line 35 being connected end-to-end in an annular shape and connecting to the outer edge of the plurality of first wirings 33 and the plurality of second wirings 34, and the other edge line 35 being connected end-to-end in an annular shape and connecting to the inner edge of the plurality of first wirings 33 and the plurality of second wirings 34. Alternatively, the watch strap may include two edge lines 35, which are located on opposite sides of the plurality of first wirings 33 and the plurality of second wirings 34 along the width direction of the watch strap, and the two edge lines extend along the length direction of the watch strap so that the edge lines connect the plurality of first wirings 33 and / or the plurality of second wirings 34.

[0069] In some embodiments, the spacing between the multiple first traces 33 is equal, and the spacing between the multiple second traces 34 is equal. This makes the multiple hollow portions 31 of the interlayer 30 more evenly distributed, which helps to make the interlayer 30 evenly connected to the first soft layer 10 and the second soft layer 20. This balances the anti-stretching effect of the interlayer 30 on the first soft layer 10 and the second soft layer 20, making the anti-stretching properties of the strap relatively consistent throughout, and improving the overall wearing comfort of the strap. In addition, the evenly spaced hollow portions 31 can better disperse the force on the interlayer 30 when the first soft layer 10 and the second soft layer 20 stretch, preventing excessive deformation of the interlayer 30 and ensuring the structural stability and reliability of the interlayer 30.

[0070] For example, the spacing between the plurality of first traces 33 is equal to the spacing between the plurality of second traces 34.

[0071] In some embodiments, the first soft layer 10 has a plurality of first snap holes 12 spaced apart along the length of the watch strap, and the second soft layer 20 has a plurality of second snap holes 21 spaced apart along the length of the watch strap, with each of the first snap holes 12 and the second snap holes 21 corresponding to one another. The interlayer 30 has clearance holes 32, through which the plurality of first snap holes 12 and the plurality of second snap holes 21 are connected. By providing clearance holes 32 on the interlayer 30, the arrangement area of ​​the interlayer 30 on the first soft layer 10 is larger, increasing the anti-stretching effect of the interlayer 30 on the first soft layer 10 and the second soft layer 20. The interlayer 30 can connect the corresponding first snap holes 12 and second snap holes 21 through the clearance holes 32, so that a predetermined component can pass through the watch strap through the clearance holes 32 and the corresponding first snap holes 12 and second snap holes 21. For example, the watch tongue can pass through the clearance holes 32 and the corresponding first snap holes 12 and second snap holes 21 to achieve a connection between two watch straps.

[0072] For example, as shown in Figures 1 and 3, the interlayer 30 is arranged in a ring shape. The interlayer 30 can be arranged around the outer periphery of the plurality of first snap holes 12 and the plurality of second snap holes 21, and can connect the plurality of first snap holes 12 and the plurality of second snap holes 21 through the clearance hole 32 in its middle.

[0073] Specifically, the first snap-fit ​​hole 12 can be integrally injection molded with the first soft layer 10, and the second snap-fit ​​hole 21 can be integrally injection molded with the second soft layer 20. Alternatively, the first snap-fit ​​hole 12 and the second snap-fit ​​hole 21 can be formed by cutting after the first soft layer 10 and the second soft layer 20 are separately formed and connected.

[0074] For example, the projections of the plurality of first snap-fit ​​holes 12 and the plurality of second snap-fit ​​holes 21 along the first direction are located within the projection of the avoidance hole 32 along the first direction. In this way, when the plurality of first snap-fit ​​holes 12 and the plurality of second snap-fit ​​holes 21 are formed by stamping or cutting, the interlayer 30 can be avoided, preventing the interlayer 30 from being affected by external forces, which would affect the connection stability between the interlayer 30 and the first soft layer 10, as well as between the interlayer 30 and the second soft layer 20.

[0075] In some embodiments, the first soft layer 10 is made of a transparent or semi-transparent material, and a printed layer (not shown) is provided between the first soft layer 10 and the interlayer 30; and / or, the second soft layer 20 is made of a transparent or semi-transparent material, and a printed layer is provided between the second soft layer 20 and the interlayer 30. It is understood that by providing a printed layer between the first soft layer 10 and the interlayer 30, and / or providing a soft layer between the second soft layer 20 and the interlayer 30, specific patterns or text on the printed layer can be observed through the first soft layer 10 and / or the second soft layer 20, improving the aesthetics of the watch strap. Simultaneously, the first soft layer 10 and the second soft layer 20 remain on the outermost side of the watch strap, which helps ensure comfort when the watch strap contacts the user's skin and protects the printed layer.

[0076] Of course, in other embodiments, the first soft layer 10 and the second soft layer 20 may also be made of non-transparent materials.

[0077] This application also provides a watch, which includes a dial and the aforementioned watch strap, the watch strap being connected to the dial. It is understood that the user can wear the watch stably, the watch dial can fit snugly against the user's skin, the watch strap achieves a balance between softness and flexibility, and the watch strap provides a relatively soft feel to the user, while not being overly tight on the user's wrist or arm, thus improving the user's wearing comfort.

[0078] For example, a watch includes a dial and two straps, one end of which is connected to the dial along its length, and the other end of which is connected to each other along its length.

[0079] For example, the watch face is equipped with sensors, such as a blood oxygen sensor and a heart rate sensor. When a user wears the watch, the strap is tightly fastened to the wrist, and the sensors on the watch face can stably and closely adhere to the user's skin, enabling the monitoring of the user's physical condition.
