Abstract

Disclosed are a wristband and a wrist-worn device. The wristband includes a band body part and a memory metal part provided to the band body part. The band body part has two end portions separable from each other. The memory metal part has a memory state of being ring-shaped in a natural state, so that the band body part naturally maintains a ring shape, and the wristband naturally maintains a wearing state.

First claim

What is claimed is:

1. A wristband, comprising:
a band body part having two end portions separable from each other; and
a memory metal part provided to the band body part; wherein
the memory metal part has a memory state of being ring-shaped in a natural state, so that the band body part naturally maintains a ring shape, and the wristband naturally maintains a wearing state;
a first installation cavity is provided inside the band body part, the first installation cavity penetrates an end portion of the band body part, and the memory metal part is accommodated and installed in the first installation cavity; the wristband is further provided with a covering cap, and the covering cap is sleeved on the end portion of the band body part penetrated by the first installation cavity;
an end portion of the memory metal part is configured to be spherical or near spherical; and/or
an installation groove for accommodating the spherical or near-spherical end portion of the memory metal part is formed on the covering cap.

2. The wristband of claim 1 , wherein there is a gap between the two end portions of the band body part in the wearing state; or
the two end portions of the band body part are overlapped in the wearing state; or
the two end portions of the band body part are abutted jointed in the wearing state.

3. The wristband of claim 1 , wherein the two end portions of the band body part are overlapped in the wearing state, and at least one of two opposite surfaces of the overlapped two end portions is provided with protrusions; or two opposite surfaces of the overlapped two end portions are adhered by a hook and loop fastener.

4. The wristband of claim 1 , wherein a material of the band body part comprises fabric and/or soft rubber and/or hard rubber; and/or
the memory metal part comprises a memory metal wire and/or a memory metal sheet.

5. The wristband of claim 1 , wherein the memory metal part comprises a plurality of strip-shaped memory metal pieces parallel to each other, the memory metal pieces are in a strip shape extending along a length direction of the band body part, and at least two of the memory metal pieces are configured to be respectively close to two opposite sides of the band body part; or
the memory metal part comprises a plurality of strip-shaped memory metal pieces, at least one of the memory metal pieces has at least one bent portion within a plane perpendicular to a thickness direction of the band body part and is bent to be ring-shaped with a side of the plane perpendicular to the thickness direction of the band body part as an inner side, and the bent portions of at least two of the memory metal pieces intersect or do not intersect when there are a plurality of memory metal pieces having the bent portion.

6. The wristband of claim 1 , further comprising an installation part provided on the band body part, a second installation cavity is provided inside the installation part, and the second installation cavity is configured to accommodate and install a device body of a wrist-worn device; and/or
the installation part is further provided with an opening communicating with the second installation cavity.

7. A wrist-worn device, comprising:
a device body; and
the wristband according to claim 1 ,
wherein the device body provided on the wristband.

8. The wrist-worn device of claim 7 , wherein the device body is a watch body or a health monitoring module.
