[0035] See also Figure 1 , is a schematic diagram of the structure of a smart watch 100 provided by an embodiment of the utility model, and the smart watch 100 includes a host 10 and a watch band 20. Figures 2 to 4The host 10 is provided with a first abutting portion 11, a second abutting portion 12 and a first buckling portion 13, the strap 20 includes a head portion 21 and a main body portion 22 connected to each other, the head portion 21 is provided with a third abutting portion 211, a fourth abutting portion 212 and a second buckling portion 213, the third abutting portion 211 abuts against the first abutting portion 11 to position the host 10 and the head portion 21 along the width direction x and the length direction y of the host 10, the fourth abutting portion 212 abuts against the second abutting portion 12, and the second buckling portion 213 buckles against the first buckling portion 13 to position the host 10 and the head portion 21 along the thickness direction z of the host 10.

[0036] In this embodiment, the host 10 is provided with a first abutting portion 11, a second abutting portion 12 and a first buckling portion 13, and the head grain portion 21 of the strap 20 is provided with a third abutting portion 211, a fourth abutting portion 212 and a second buckling portion 213 accordingly. When the strap 20 is assembled to the host 10, the first abutting portion 11 abuts against the third abutting portion 211, and the host 10 and the head grain portion 21 of the strap 20 are positioned along the width direction x and the length direction y of the host 10. At the same time, the second buckling portion 213 is buckled with the first buckling portion 13, and the fourth abutting portion 212 abuts against the second abutting portion 12, so that the host 10 and the head grain portion 21 can be positioned along the thickness direction z of the host 10. In this way, the host 10 and the head grain portion 21 are completely positioned in the width direction x, the length direction y and the thickness direction z, and the fixed assembly of the host 10 and the head grain portion 21 is realized, and the body portion 22 is also fixedly assembled to the host 10 along with the head grain portion 21. When the strap 20 is detached from the host 10, the second buckling portion 213 and the first buckling portion 13 are designed to be detachable. The second buckling portion 213 can be separated from the first buckling portion 13, so that the fourth abutting portion 212 and the second abutting portion 12 can also be separated, thereby releasing the positioning of the host 10 and the head particle part 21 along the thickness direction z, and the head particle part 21 can be separated from the host 10 along the thickness direction z, so that the third abutting portion 211 is separated from the first abutting portion 11, and the positioning of the host 10 and the head particle part 21 along the width direction x and the length direction y is released, and the head particle part 21 and the host 10 are disassembled. The main body part 22 is also separated from the host 10 along with the head particle part 21. The strap 20 is easy to disassemble and assemble, which is convenient for replacing the strap 20 of the smart watch 100.

[0037] In some embodiments, Figure 5 and Figure 6As shown, the second abutting portion 12 is the first surface of the first abutting portion 11 facing the third abutting portion 211 along the thickness direction z, the fourth abutting portion 212 is the second surface of the third abutting portion 211 facing the first abutting portion 11 along the thickness direction z, the fourth abutting portion 212 abuts against the second abutting portion 12 to limit the movement of the head grain portion 21 relative to the host 10 along the direction of the second surface, and the side of the second buckling portion 213 facing the same direction as the second surface abuts against the side of the first buckling portion 13 facing the same direction as the first surface to limit the movement of the head grain portion 21 relative to the host 10 along the direction of the first surface. In this way, on the one hand, by abutting the first surface against the second surface, the abutting area can be increased, thereby improving the reliability of limiting the movement of the head grain portion 21 relative to the host 10 along the direction of the second surface. On the other hand, the second abutting portion 12 is a part of the first abutting portion 11, and the fourth abutting portion 212 is a part of the second abutting portion 12, which can simplify the overall structure of the head grain portion 21 and the host 10, which is conducive to the miniaturization design of the smart watch 100.

[0038] For example, Figure 7 As shown, the second buckling portion 213 includes a deformation portion 213a and a bent portion 213b bent and connected to the deformation portion 213a. The deformation portion 213a can be deformed relative to the head granule portion 21, so that the side of the bent portion 213b facing the same direction as the second surface abuts against the side of the first buckling portion 13 facing the same direction as the first surface, or so that the bent portion 213b is separated from the first buckling portion 13. In this way, the deformation portion 213a is deformed relative to the head granule portion 21, so that the bent portion 213b abuts against the first buckling portion 13, thereby realizing the buckling of the second buckling portion 213 with the first buckling portion 13. At the same time, the deformation portion 213a can be deformed relative to the head granule portion 21, so that the bent portion 213b is separated from the first buckling portion 13, thereby realizing the separation of the second buckling portion 213 with the first buckling portion 13. The detachable design of the second buckling portion 213 and the first buckling portion 13 is realized by deformation, the structure is relatively simple and reliable, and the operation difficulty is relatively low.

[0039] Optionally, combined Figure 2 and Figure 7As shown, the strap 20 further includes a decorative piece 30, which is detachably connected to the host 10, and the decorative piece 30 abuts against the side of the deformable portion 213a away from the first buckling portion 13 to limit the deformation of the deformable portion 213a. In this way, by installing the decorative piece 30 on the host 10, the decorative piece 30 can abut against the side of the deformable portion 213a away from the first buckling portion 13, avoiding the deformation of the deformable portion 213a and accidentally causing the second buckling portion 213 to separate from the first buckling portion 13. When the decorative piece 30 is detached from the host 10, the decorative piece 30 separates from the deformable portion 213a, and the deformable portion 213a can be deformed, so that the bent portion 213b is separated from the first buckling portion 13, thereby achieving the separation of the second buckling portion 213 from the first buckling portion 13.

[0040] In some embodiments, the decorative member 30 includes a main body 31 and an extension 32, wherein the main body 31 is detachably connected to the host 10, and the extension 32 is disposed on the main body 31, and the extension 32 abuts against the side of the deformable portion 213a away from the first buckling portion 13 to limit the deformation of the deformable portion 213a. In this way, by connecting the main body 31 to the host 10, the extension 32 can abut against the side of the deformable portion 213a away from the first buckling portion 13, thereby preventing the deformation of the deformable portion 213a from accidentally causing the second buckling portion 213 to separate from the first buckling portion 13, and when the main body 31 is detached from the host 10, the extension 32 is detached from the host 10, and the extension 32 is separated from the deformable portion 213a, and the deformable portion 213a can be deformed, so that the bent portion 213b is separated from the first buckling portion 13, thereby achieving the separation of the second buckling portion 213 from the first buckling portion 13.

[0041] Alternatively, if Figure 7 As shown, the head grain part 21 is further provided with a second fixing part 214, which is located at the side of the deformation part 213a away from the first buckle part 13 and is spaced from the deformation part 213a, and the side of the extension part 32 away from the deformation part 213a abuts against the second fixing part 214. In this way, by the second fixing part 214 abutting against the side of the extension part 32 away from the first buckle part 13, the extension part 32 is squeezed in the interval between the second fixing part 214 and the deformation part 213a, the reliability of the extension part 32 and the head grain part 21 can be improved, and the extension part 32 can effectively prevent the deformation of the deformation part 213a.

[0042] In some embodiments, the third abutment portion 211 is provided on one side of the head part 21 along the thickness direction z, the decorative element 30 is located on the side of the head part 21 where the third abutment portion 211 is provided, and the decorative element 30 covers the third abutment portion 211. In this way, by covering the third abutment portion 211 with the decorative element 30, the decorative element 30 can maintain the integrity of the appearance of the smart watch 100.

[0043] For example, Figure 2 As shown, the host 10 is further provided with a third buckling portion 14, and the decorative piece 30 is provided with a fourth buckling portion 30a, which is detachably buckled with the third buckling portion 14 to position the decorative piece 30 and the host 10 along the thickness direction z. In this way, by designing that the fourth buckling portion 30a is detachably buckled with the third buckling portion 14, the difficulty of disassembling and assembling the decorative piece 30 and the host 10 is relatively low, which can reduce the difficulty of disassembling and assembling the strap 20 of the smart watch 100, and facilitate the replacement of the strap 20 of the smart watch 100.

[0044] Optionally, the host 10 is provided with two third buckling parts 14, the two third buckling parts 14 are arranged at intervals along the width direction x, and the decorative member 30 is provided with two fourth buckling parts 30a, the two fourth buckling parts 30a are arranged at intervals along the width direction x, and the two fourth buckling parts 30a are buckled one by one with the two third buckling parts 14. In this way, by using the method of buckling the two fourth buckling parts 30a with the two third buckling parts 14 one by one, the connection strength of the decorative member 30 assembled on the host 10 is relatively high, and the effect of the decorative member 30 on limiting the deformation of the deformation part 213a is effectively ensured.

[0045] In some embodiments, one of the first abutting portion 11 and the third abutting portion 211 is a raised portion, and the other is a recessed portion, and the raised portion is embedded in the recessed portion to position the host 10 and the head particle portion 21 along the width direction x and the length direction y of the host 10. In this way, the first abutting portion 11 and the second grounding portion adopt the design of the raised portion and the recessed portion, the matching structure is relatively simple, and the operation of embedding the raised portion into the recessed portion and separating the raised portion from the recessed portion is relatively simple, which can reduce the difficulty of disassembling the head particle portion 21 and the host 10.

[0046] Optionally, the first abutting portion 11 is a raised portion, the third abutting portion 211 is a recessed portion, two first abutting portions 11 and a first buckling portion 13 are provided on one side of the host 10 along the length direction y, the two first abutting portions 11 are spaced apart along the width direction x, the first buckling portion 13 is located between the two first abutting portions 11, and the second buckling portion 213 is provided at the third abutting portion 211. In this way, through the cooperation of the two first abutting portions 11 and the third abutting portion 211, the head grain portion 21 is assembled to the host 10 with a high connection strength, which effectively ensures the stable connection between the strap 20 and the host 10.

[0047] For example, see again Figure 2 and Figure 3The first abutting portion 11 includes a first convex portion 11a and a second convex portion 11b, the first convex portion 11a is provided on the main unit 10, and the first convex portion 11a is extended along the length direction y, the second convex portion 11b is provided on the first convex portion 11a, and the second convex portion 11b is extended along the width direction x, the third abutting portion 211 includes a first groove 211a and a second groove 211b connected to the first groove 211a, the first groove 211a is extended along the length direction y, the second groove 211b is extended from the first groove 211a along the width direction x, the first convex portion 11a is embedded in the first groove 211a to position the main unit 10 and the head particle part 21 along the width direction x, and the second convex portion 11b is embedded in the second groove 211b to position the main unit 10 and the head particle part 21 along the length direction y. In this way, the first protrusion 11a is embedded in the first groove 211a, and the first protrusion 11a can position the main unit 10 and the head particle part 21 along the width direction x. The second protrusion 11b is embedded in the second groove 211b, and the second protrusion 11b can position the main unit 10 and the head particle part 21 along the length direction y, thereby realizing the horizontal positioning of the head particle part 21 and the main unit 10, that is, the width direction x and the length direction y.

[0048] The embodiment of the utility model provides a smart watch 100, wherein the host 10 is provided with a first abutting portion 11, a second abutting portion 12 and a first buckling portion 13, and the head grain portion 21 of the strap 20 is provided with a third abutting portion 211, a fourth abutting portion 212 and a second buckling portion 213 accordingly.

At the same time, the second buckling portion 213 is buckled with the first buckling portion 13, and the fourth abutting portion 212 abuts against the second abutting portion 12, so that the host 10 and the head grain portion 21 can be positioned along the thickness direction z of the host 10. In this way, the host 10 and the head grain portion 21 are completely positioned in the width direction x, the length direction y and the thickness direction z, and the fixed assembly of the host 10 and the head grain portion 21 is realized, and the body portion 22 is also fixedly assembled to the host 10 along with the head grain portion 21.
