Abstract

Disclosed is wristband and wrist wearable device, including: a wristband body portion, one end is connected to one end of a device body of a wrist wearable device, and the other end is a free end; and a memory metal portion, which is arranged on the wristband body portion and has an arc-shaped memory state in a natural state, so that the wristband body portion is naturally maintained in an arc shape. The memory metal portion comprises a strip-shaped memory metal piece including a first metal segment, a second metal segment, and a third metal segment that are sequentially connected, the first metal segment and the third metal segment extend along a length direction of the wristband body portion in parallel, the second metal segment is arranged at the free end of the wristband body portion and is provided with at least one bent portion.

First claim

The invention claimed is:

1. A wristband, comprising:
two wristband body portions, one end of each of the two wristband body portions connects to one end of a device body of a wrist wearable device, and another end of each of the two wristband body portions is a free end; and
a memory metal portion, which is arranged on each of the two wristband body portions and has an arc-shaped memory state in a natural state, so that each of the two wristband body portions is naturally maintained in an arc shape, and the wristband is naturally maintained in a wearing state;
an arc of each of the two wristband body portions subtends an angle of less than 180 degrees; and
the free ends of the two wristband body portions are overlapped with each other, at least one of two contacting opposite surfaces of the two overlapped free ends is provided with flexible embossments.

2. A wrist wearable device, comprising a device body and the wristband according to claim 1 .

3. The wrist wearable device according to claim 2 , wherein a mounting slot is arranged at an end of the device body, and a buckling hole is arranged at the mounting slot; a connecting portion of the wristband is connected to the mounting slot in a pluggable manner, and a buckling groove is arranged on the connecting portion;
the wrist wearable device further comprises a buckling block; after the connecting portion is inserted into the mounting slot, the buckling groove aligns with the buckling hole, the buckling block penetrates through the buckling hole and is buckled to the buckling groove, and the buckling block is magnetically attracted to the connecting portion to lock the wristband in the mounting slot.

4. The wrist wearable device according to claim 3 , wherein at least one of the connecting portion and the buckling block is a magnet.

5. A wristband, comprising:
a wristband body portion, one end of the wristband body portion is configured to connect to one end of a device body of a wrist wearable device, and another end of the wristband body portion is a free end;
a memory metal portion, which is arranged on the wristband body portion and has an arc-shaped memory state in a natural state, so that the wristband body portion is naturally maintained in an arc shape, and the wristband is naturally maintained in a wearing state; and
a connecting portion configured to be connected with one end of the device body of the wrist wearable device,
wherein the memory metal portion comprises a strip-shaped memory metal piece, and the memory metal piece comprises a first metal segment, a second metal segment, and a third metal segment that are sequentially connected, the first metal segment and the third metal segment both extend along a length direction of the wristband body portion and are arranged in parallel, the second metal segment is arranged at the free end of the wristband body portion, and the second metal segment is provided with at least one bent portion; and
a mounting hole located inside the at least one bent portion is arranged at a free end of the wristband body portion.
