Housing assembly and foldable electronic device

Abstract

The present application provides a shell assembly and a foldable electronic device, comprising: a linkage mechanism, a first body, a second body, a third body, a first rotating shaft structure and a second rotating shaft structure, wherein the first body and the second body are folded or unfolded through the first rotating shaft structure, and the second body and the third body are folded or unfolded through the second rotating shaft structure; the linkage mechanism comprises a moving block and a first locking attachment; the two ends of the moving block are respectively connected to the first rotating shaft structure and the first locking attachment; the second rotating shaft structure is provided with a second locking attachment; when the first body, the second body and the third body are flattened, the first locking attachment and the second locking attachment are locked to prevent the second rotating shaft structure from folding; when the first body and the second body are folded through the first rotating shaft structure, the first rotating shaft structure drives the first locking attachment to move through the moving block to unlock the first locking attachment and the second locking attachment. The setting of the linkage mechanism makes it impossible for the second rotating shaft structure to fold before the first rotating shaft structure is folded, thereby ensuring the opening and closing sequence.
