In the embodiment of the present invention, when the smart host 20 rotates relative to the bottom chassis 10, because one end of the side band 30 is coupled to the first end of the bottom chassis 10 through the first rotating shaft 21, the coaxial rotation design of the first rotating shaft 21 is shared among the one end of the side band 30, the first end of the bottom chassis 10, and one end of the smart host 20, so as to reduce the component design of the wearable device, simplify the component assembly process of the wearable device, and further make the structure of the wearable device more compact.

In the embodiment of the present invention, a top surface display screen (not labeled in the figure) may be disposed on the top surface 20a of the intelligent host 20; optionally, a bottom display screen (not labeled) may also be disposed on the host bottom surface 20b of the smart host 20. Projection devices (not shown) of the smart host 20 may be disposed on the host top surface 20a, the host bottom surface 20b, and the side surfaces of the smart host 20. In a normal case, the smart host 20 may be stacked on the bottom bracket 10, that is, the host bottom surface 20b of the smart host 20 is attached to the upper surface of the bottom bracket 10; when the smart host 20 rotates around the first rotation axis 21, the top surface 20a and the bottom surface 20b of the smart host 20 both form a certain angle with the upper surface of the bottom bracket 10.

It should be known that, inside each above-mentioned device, functional module all located intelligent host 20, and be connected with the mainboard electricity, realize the control to these devices, functional module through the mainboard, and then control it and realize corresponding function.

Therefore, in the embodiment of the present invention, the smart host 20 is different from a traditional watch dial that only can implement functions of time display, timing, and the like.

Further, since the smart host 20 and the bottom bracket 10 can be rotatably connected through the first rotating shaft 21, the rotation angles of the camera module 22 and the camera module 23 can be adjusted by adjusting the rotation angles of the smart host 20 and the bottom bracket 10. For example, when the smart host 20 is stacked on the bottom chassis 10, the angle between the smart host 20 and the bottom chassis 10 is 0 °, and when the smart host 20 is rotated, the angle between the smart host 20 and the bottom chassis 10 may preferably be 90 °. When the angle between the intelligent host 20 and the bottom bracket 10 is 0 degree, the included angle between the shooting module 22 and the shooting module 23 on the intelligent host 20 relative to the bottom bracket 10 is also 0 degree; when intelligent host 20 rotated the relative bottom support 10 and formed 90 contained angles, intelligent host 20's shooting module 22 and shooting module 23 contained angle relative bottom support 10 were 90 contained angles to can realize shooting module 22 and the adjustment of shooting module 23's shooting angle.

Therefore, the bottom bracket 10 not only can realize the function of bearing the rotation of the smart host 20, but also can realize the effect of insulating the smart host 20 from the wrist skin of the user.

Further, when the bottom bracket 10 is a plate-shaped structure, one or more through holes 10a may be disposed on the bottom bracket 10, so that the smart host 20 may implement various physiological feature detections including detection of the heart rate of the user through the through holes 10 a. The shape of the through hole 10 may be circular, square, or oval, and the embodiment of the present invention is not limited.
