Abstract: A wearable device and an airbag preparation method. The wearable device includes a watch body, an airbag, and an airbag cover. The airbag is detachably connected to an end of the watch body, so that a coverage area of the airbag for the watch body is small, thereby reserving space for installing another module on the watch body. The airbag includes a first layer structure and a second layer structure that are superposed. The first layer structure has a first cavity, the second layer structure has a second cavity, and the first cavity communicates with the second cavity.

Abstract: A connection structure includes a first foldable plate, a second foldable plate, and an elastic shaft. The first foldable plate includes a first support strip and a second support strip having a first gap therebetween, and a first clamping portion is disposed on two side faces facing each other. The second foldable plate includes a third support strip and a fourth support strip having a second gap therebetween, and a second clamping portion is disposed on two side faces facing away each other. The elastic shaft passes through the second gap, and its two ends are respectively connected to the third support strip and the fourth support strip. When the first foldable plate and the second foldable plate are in a closed state, the third support strip and the fourth support strip are located in the first gap, and the first clamping portion is clamped to the second clamping portion.

Abstract: This application relates to a spring bar assembly, a watch strap, and a watch. The spring bar assembly includes a mounting base, a spring bar, a button, and a lever. Both the spring bar and the button are mounted on the mounting base. The button is capable of moving relative to the mounting base, and a movement direction of the button is perpendicular to an axial direction of the spring bar. One end of the lever extends into a guide groove of the button and abuts against first side walls of the guide groove, and the other end of the lever is connected to the spring bar. The button is capable of driving the spring bar to move relative to the mounting base in the axial direction of the spring bar by using the lever.
