Title:
FOLDABLE MODULE AND FOLDABLE ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/259526
Kind Code:
A1
Abstract:
Disclosed is a foldable module, comprising: a first connection portion (20), a first mandrel (10), a first driving ring (30), and a first spring (40), wherein a first shaft hole is provided in the first connection portion (20), and the first mandrel (10) passes through the first driving ring (30), the first shaft hole, and the first spring (40); a first protrusion (202) and a first recess (301) are provided between the first driving ring (30) and the first connection portion (20), the first protrusion (202) is located between the first spring (40) and the first recess (301), or the first recess (301) is located between the first spring (40) and the first protrusion (202); and when the first connection portion (20) rotates, the first protrusion (202) slides out of the first recess (301). During folding or unfolding, the first protrusion (202) slides out of the first recess (301) to provide a damping force for the unfolding or folding; and compared to the first driving ring being driven to rotate by means of the cooperation of a first driving surface on a rotating shaft and a second driving surface on the first driving ring, the first connection portion (20) can directly drive the first protrusion (202) and the first recess (301) to move relatively, and the transmission precision is improved. A foldable electronic device comprising the foldable module (1) is also provided.
