[0032] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and will be described in more detail hereinafter. These drawings and the textual description are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by reference to specific embodiments. Detailed Description of the Embodiments

[0033] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of structures consistent with some aspects of the present application as detailed in the appended claims.

[0034] First, the terms related to the present application are explained:

[0035] Watch case: It is the outer shell component of the watch body (watch head), used to directly enclose and protect the internal components of the watch, such as the movement, dial, hands, etc.

[0036] Lug: It is an important component of the watch. Specifically, it refers to the protruding part of the watch case for connecting the watch band.

[0037] Spring bar: It is a key component in the watch for connecting the watch band and the watch case. Generally, it is a steel rod between the watch band and the watch case, used to fix the watch band and ensure its stable connection with the watch case.

[0038] In the prior art, in the designs of many watches, the watch band and the watch case are connected by a spring bar. The spring bar usually consists of a rod body, a spring bar head, and a spring. The rod body is the main part of the spring bar, responsible for passing through the holes of the watch band and the watch case; the spring bar head is located at one end of the rod body for fixing the watch band; the spring is located inside the spring bar, providing the necessary elastic force to ensure the tight connection between the watch band and the watch case.

[0039] When connecting the watch band and the watch case through a spring bar, it is necessary to assemble all the above parts, involving a large number of small parts; when using parts such as spring bars to connect the watch case and the watch band, the operation is troublesome. The spring bar is generally made of materials such as stainless steel and titanium alloy. The manufacturing process of the spring bar requires high-precision processing equipment and technology, and its manufacturing cost is high.

[0040] In summary, in the prior art, the structure of connecting the watch band and the watch case through a spring bar has technical problems such as a large number of parts, troublesome operation, and high cost.

[0041] A connection structure between a watch case and a watch band provided by the present application includes a first connection portion provided on a lug of the watch and a second connection portion provided in a headpiece of the watch band; or a second connection portion provided on a lug of the watch and a first connection portion provided in a headpiece of the watch band; the first connection portion and the second connection portion are snap-fitted by pressing; thereby realizing a tight connection between the watch case and the watch band, achieving the effects of reducing the number of parts for connecting the watch case and the watch band, being convenient and efficient in assembly, and having a lower cost, and solving the technical problems of a large number of parts, troublesome operation, and high cost existing in the prior art.

[0042] The following will detail the technical solution of the present application and how the technical solution of the present application solves the above technical problems through specific embodiments. These several specific embodiments below can be combined with each other, and concepts or processes that are the same or similar may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0043] Combined Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , Figure 1 is a perspective view of the first connection portion provided by the present application; Figure 2 is a top view of the first connection portion provided by the present application; Figure 3 is a perspective view of the second connection portion provided by the present application; Figure 4 is a front view of the second connection portion provided by the present application.

[0044] As Figure 1 and Figure 2 show, a lug 110 is fixed on each of two opposite sides of the watch case, Figure 1 and Figure 2 show the structure of the lug 110 on one side.

[0045] As Figure 3 and Figure 4 show, headpieces 120 are provided at both ends of the watch band 140, Figure 3 and Figure 4 show the structure of the headpiece 120 at one end.

[0046] In this embodiment, the connection structure between the watch case 130 and the watch band 140 includes a first connection portion and a second connection portion. In one example, the first connection portion is provided on the lug 110; the second connection portion is provided on the headpiece 120. In one example, the first connection portion is provided on the headpiece 120; the second connection portion is provided on the lug 110. Hereinafter, the example where the first connection portion is provided on the lug 110 and the second connection portion is provided on the headpiece 120 will be used for illustration.

[0047] As Figure 1 andFigure 2 As shown, the first connecting portion includes a receiving groove 10. A positioning hole 12 is provided on each of the two first side walls 11 that are parallel and opposite to each other in the receiving groove 10; alternatively, a plurality of positioning holes 12 may be provided on the first side wall 11, and a corresponding plurality of positioning holes 12 are provided on the other first side wall 11 that is parallel and opposite to it.

[0048] As Figure 3 and Figure 4 shown, the second connecting portion includes two parallel fixing posts 13, and the space between the two fixing posts 13 is hollow; a limiting post 14 is provided on each fixing post 13. When a plurality of positioning holes 12 are provided on the first side wall 11 of the first connecting portion, the same number of limiting posts 14 are correspondingly provided on each fixing post 13.

[0049] The first connecting portion and the second connecting portion are snapped together to connect the watch case 130 and the watch band 140. When the second connecting portion is snapped onto the first connecting portion, since the space between the two fixing posts 13 is hollow, the two fixing posts 13 are deformed in the receiving groove 10 so that a limiting post 14 on each fixing post 13 is respectively assembled into the corresponding positioning hole 12; after the second connecting portion is snapped onto the first connecting portion, the two fixing posts 13 are respectively in contact with the two first side walls 11.

[0050] Figure 5 is a schematic cross-sectional view of the first connecting portion and the second connecting portion after being snapped together provided by this application. As Figure 5 shown, connection structures for the watch case 130 and the watch band 140 are respectively provided in the lugs 110 and the watch band head beads 120. Through the connection structures, the connection between the watch case 130 and the watch band 140 is realized.

[0051] The above connection structure can be used in various portable watches (such as wristwatches, pocket watches). The watch case can be a watch case of various materials, and the watch band can be a watch band of various materials.

[0052] For the connection structure of the watch case and the watch band provided by the embodiments of this application, a first connecting portion is provided on the lugs of the watch, and a second connecting portion is provided in the watch band head beads of the watch; or a second connecting portion is provided on the lugs of the watch; a first connecting portion is provided in the watch band head beads of the watch; the first connecting portion and the second connecting portion are pressed and snapped together to tightly connect the watch case and the watch band of the watch, achieving the effects of reducing the number of parts for connecting the watch case and the watch band, while being convenient, efficient, and having a lower cost during assembly.

[0053] In some embodiments of this embodiment, the first connecting portion further includes a guiding groove 15 provided on each first side wall 11. The guiding groove 15 is located above each positioning hole 12. Among them, during the process of snapping the second connecting portion onto the first connecting portion, the guiding groove 15 is used to deform the two fixing posts 13 in the receiving groove 10.

[0054] When the user manually snaps the second connecting part onto the first connecting part, the above-mentioned guiding groove 15 can assist the user in deforming the two fixing columns 13 within the receiving groove 10, reducing the operation complexity.

[0055] Specifically, when the second connecting part is snapped onto the first connecting part, the guiding groove 15 contacts the limiting post 14, and the surface of the guiding groove 15 for contacting the limiting post 14 is an inclined plane.

[0056] The above-mentioned inclined plane can be an inclined flat surface. When using the inclined flat surface to snap the second connecting part onto the first connecting part, the guiding groove 15 can generate a continuous deforming force on the two fixing columns 13, thereby assisting the user in snapping the limiting post 14 on the fixing column 13 into the positioning hole 12.

[0057] In some embodiments of the present embodiment, the guiding grooves 15 located on the two first side walls 11 are arranged oppositely, and the first distance between the two oppositely arranged guiding grooves 15 is greater than the second distance;

[0058] Wherein, the first distance is the distance between the first ends of the two guiding grooves 15, the second distance is the distance between the second ends of the two guiding grooves 15, the first end is the end of the guiding groove 15 far from the positioning hole 12, and the second end is the end of the guiding groove 15 close to the positioning hole 12.

[0059] The fact that the first distance is greater than the second distance makes the surface of the guiding groove 15 for contacting the limiting post 14 an inclined plane. During the process of snapping the second connecting part onto the first connecting part, the limiting post 14 contacts the inclined plane of the guiding groove 15, and the guiding groove 15 applies a continuously increasing force to the fixing column 13 through the limiting post 14, gradually reducing the hollow distance between the two fixing columns 13 until the limiting post 14 slides into the positioning hole 12 below the guiding groove 15, thereby achieving the snapping of the first connecting part and the second connecting part.

[0060] In some embodiments of the present embodiment, the second connecting part further includes a first solid part 19 provided on the second main body, and there is a first opening 16 between the first solid part 19 and the two fixing columns 13.

[0061] The first solid part 19 can be connected to the body of the watchband headpiece 130, one end is used for fixing to the body, and the other end is used for connecting to the two parallel fixing columns 13. The first opening 16 is formed by opening in the direction away from the body in the middle between the two ends of the first solid part 19. The first solid part 19 is used for fixing and supporting the fixing columns 13. After the first connecting part and the second connecting part are snapped together, the first solid part 19 can also relieve the external force on the fixing columns 13 to stabilize the connection between the first connecting part and the second connecting part; at the same time, the first opening 16 ensures that the two fixing columns 13 can be squeezed and deformed, thereby achieving the snapping of the limiting post 14 and the positioning hole 12.

[0062] In some embodiments of the present embodiment, the receiving groove 10 includes a second side wall 17 that is connected to both first side walls 11 simultaneously. The receiving groove 10 includes a second opening 18 that is disposed opposite to the second side wall 17. When the first connecting portion and the second connecting portion are snapped together, the first solid portion 19 is located outside the second opening 18, and the surfaces of the first solid portion 19 located outside the second opening 18 are in contact with the two first side walls 11 respectively.

[0063] After the first connecting portion and the second connecting portion are snapped together, the surfaces of the first solid portion 19 of the second connecting portion located outside the second opening 18 are in contact with the two first side walls 11 of the first connecting portion respectively. One end of the first solid portion 19 of the second connecting portion close to the fixing post 13 is in contact with the second side wall 17 of the first connecting portion, making the second connecting portion and the first connecting portion fit tightly after being snapped together, thereby making the connection between the watch headpiece 120 and the watch lug 110 more firm.

[0064] In some embodiments of the present embodiment, two first connecting portions are provided on the watch lug 110, and two second connecting portions are provided on the watch headpiece 120.

[0065] Wherein, when the watch case 130 is connected to the watch band 140, each second connecting portion is snapped into a corresponding first connecting portion.

[0066] The two first connecting portions and the two second connecting portions are respectively snapped and connected, increasing the connection stress points between the watch lug 110 and the watch headpiece 120, making the connection between the watch lug 110 and the watch headpiece 120 more firm.

[0067] In some embodiments of the present embodiment, the two first connecting portions are integrally formed with the body of the watch lug 110, and the two second connecting portions are integrally formed with the body of the watch headpiece 120.

[0068] The connection structure of the watch case and the watch band provided by the embodiment of the present application, by providing two first connecting portions on the watch lug of the watch and two second connecting portions in the watch headpiece, and providing guide grooves on the two first connecting portions, the two first connecting portions are respectively snapped with the two second connecting portions under the assistance of the guide grooves, making the connection operation between the watch case and the watch band more convenient and the connection between the watch lug and the watch headpiece more firm.

[0069] The embodiment of the present application further provides a watch, including: a watch body 150 and a watch band 140. A watch case 130 is provided on the watch body, and the watch case 130 and the watch band 140 are connected through the above connection structure of the watch case and the watch band.

[0070] Figure 6It is a schematic structural diagram of the connection between the watch case and the watch band on one side of a watch using the connection structure of the watch case and the watch band provided in this application. The watch case 130 is respectively provided with lugs 110 on two opposite sides, and the watch band heads 120 are respectively provided at both ends of the watch band 140. The first connecting portion is provided on the lug 110, and the second connecting portion is provided on the watch band head 120; or the first connecting portion is provided on the watch band head 120, and the second connecting portion is provided on the lug 110; the lug 110 and the watch band head 120 are press-fitted and connected through the first connecting portion and the second connecting portion, so as to realize the connection between the watch case 130 and the watch band 140.
