Foldable device and an electronic device

Abstract

A foldable device including a bendable mechanism, a sliding member, and a fall-induced-compression resisting mechanism is provided. The fall-induced-compression resisting mechanism includes a connection member. The sliding member includes a first stopper. When the bendable mechanism is folded, the bendable mechanism drives the connection member to move relative to the sliding member toward the first stopper until the connection member abuts against or approaches the first stopper to limit the sliding member to move toward the bendable mechanism, thus preventing the sliding member from collapsing on the bendable mechanism when the foldable device drops, and thereby preventing a flexible screen fixedly coupled to the sliding member from being arched and damaged. An electronic device including the foldable device is further provided.
