When the strap 120 moves relative to the device main body 110 between the tightened state and the released state, the friction between the two positioning bars 140 and the device main body 110 can prevent the two edges of the strap 120 from sliding unsynchronously. Move to prevent the strap 120 from skewing relative to the device main body 110.

The present invention does not limit the form of the adjustment component 130, which is illustrated by the following figures as an example. 15 is a perspective view of some components of a wearable device according to another embodiment of the present invention. Fig. 16 shows that the strap of Fig. 15 is partially wound around the scroll shaft. The difference between the embodiment shown in FIGS. 15 and 16 and the previous embodiment is that, in the embodiment shown in FIGS. 15 and 16, the adjustment assembly 130' includes a scroll shaft 132' and an actuating unit M . The scroll shaft 132' is rotatably disposed in the device main body 110, the strap 120 is connected to the scroll shaft 132', and the actuation unit M is, for example, a motor, which is disposed in the device main body 110 and is suitable for driving the scroll shaft 132' Scroll the strap 120 to adjust the strap 120 from the released state shown in FIG. 15 to the tightened state shown in FIG. 16, or to adjust the strap 120 from the tightened state shown in FIG. 16 to the tightened state shown in FIG. 15 The release state. In other embodiments, the adjustment component may be in other appropriate forms, which is not limited by the present invention.

Fig. 17 is a perspective view of a wearable device according to another embodiment of the present invention. Fig. 18 is a front view of the wearable device of Fig. 17. In the wearable device 200 of FIGS. 17 and 18, the configuration and mode of action of the device main body 210 and the adjustment components therein are the same or similar to those of the device main body 110 and the adjustment components 130 (adjustment components 130') in the foregoing embodiment. The configuration and function of) will not be repeated here. The difference between FIGS. 17 and 18 and the foregoing embodiment is that the strap 220 of the wearable device 200 includes two strap layers 222 and 224 stacked on each other. The color of the strap layer 222 is different from the color of the strap layer 224, for example. .

Fig. 19 shows that the strap of Fig. 17 is tightened. Fig. 20 shows that the strap of Fig. 18 is tightened. Fig. 21 is a partial enlarged view of the strap of Fig. 20. Due to the difference in the material properties or composition of the two strap layers 222, 224, when the strap 220 is adjusted from the released state shown in FIGS. 17 and 18 to the tightened state shown in FIGS. 19 and 20, the strap The slits 222 a (marked in FIG. 21) of the belt layer 222 become larger and the slits 222 a expose the strap layer 224.

As described above, when the strap 220 of this embodiment is adjusted to the tightened state, the gap 222a of the upper strap layer 222 becomes larger due to the stretch of the strap layer 222, so that the lower strap layer 224 penetrates the gap. 222a is exposed, so that the user can easily determine whether the strap 220 has been tightened by observing whether the lower strap layer 224 is visible. Specifically, in this embodiment, as shown in FIGS. 19 to 20, the shape of the slit 222a of the strap layer 222 can be selectively selected to be narrow and elongated and extend obliquely, so that it is easy to increase significantly with the stretching of the material. The strap layer 224 does not have this characteristic, so as to achieve the above-mentioned visual effect.

The present invention does not limit the number and form of the strap layers. In other embodiments, the strap layers can be in other numbers and forms, as long as the gap of the uppermost strap layer can be compared with the strap being stretched. The lower level is obviously larger, and the above-mentioned visual effect can be achieved. For example, the strap layer may be a woven layer, and the degree to which the gap becomes larger when it is stretched is controlled by the difference in the woven density.

In summary, the wearable device of the present invention uses the adjustment component to adjust the tightness of the strap, so the user does not need to tighten the strap and buckle it to tighten the strap, but can make the adjustment process more complicated. Simple. In addition, when the strap of the present invention is adjusted to a tightened state, the gap of the upper strap layer becomes larger due to the stretching of the strap layer, so that the lower strap layer is exposed through the gap, allowing use The user can easily determine whether the strap has been tightened by observing whether the lower strap layer is visible.
