Document Type and Number:

WIPO Patent Application WO/2022/143312

Kind Code:

A1

Abstract:

A wearable device, and a preparation method for an airbag (2), relating to the technical field of electronic devices. The wearable device comprises a watch body (1), an airbag (2) and an airbag cover plate (5). The airbag (2) is detachably connected to one end of the watch body (1), such that a coverage area of the airbag (2) on the watch body (1) is relatively small, and thus a space is reserved for mounting other modules on the watch body (1). The airbag (2) comprises a first layer structure (203a) and a second layer structure (203b) which overlap, the first layer structure (203a) is provided with a first cavity (2031), the second layer structure (203b) is provided with a second cavity (2032), and the first cavity (2031) is in communication with the second cavity (2032), such that an inflation space of the airbag (2) can be relatively large. The airbag (2) can be fixed to the watch body (1) by means of the airbag cover plate (5), which is detachably connected to the watch body (1), so as to simplify a disassembly and assembly process of the airbag (2) and the watch body (1). The degree of functional integration of the wearable device can be effectively improved, and the measurement precision of blood pressure is improved.
