EXTERNAL OPTICAL DISK DRIVE

摘要

An external optical disk drive (99) includes a bottom housing (10), a top housing (20) coupled to the bottom housing, and a cover (40) pivotably connected to the top housing. The cover is provided with a hinge member (42). An engaging piece (424) is provided on the hinge member. A torsion spring (50) is biased between the top housing and the cover. A damping unit (32) is provided between the top housing and the bottom housing. When the cover is pivoted from a closed state to an open state, the engaging piece engages interferentially with the damping unit, and a frictional force is generated between the engaging piece and the damping unit to slow down a rotating speed of the cover to cause the cover to stop at the open state without vibration.
