Abstract:
1. An emergency ejection device for a slot-in disk drive, the slot-in disk drive comprising a housing and a sliding component, the emergency ejection device comprising: a driving motor disposed inside the housing for driving a worm gear; a rotating component, a central hole of the rotating component being fixed on the housing in a rotatable manner, a sliding slot being formed on an end of the rotating component, a fixing hole being formed on the other end of the rotating component, and a buckling slot being formed on an end of the sliding slot; a gear set comprising: a locking component disposed on the housing via a hole in a rotatable manner, a sliding column protruding from an end of the locking component and inserting inside the sliding slot, and an inclined surface protruding from the other end of the locking component; and a spring, an end of the spring being fixed on a lateral side of the driving motor and the other end of the spring being fixed on a side of the locking component adjacent to the inclined surface; wherein the spring provides an elastic force for holding the sliding column inside the buckling slot so as to constrain the buckling slot to move in a rotary direction of the rotating component and to keep engagement of the clutching gear with the second gear.
