Abstract
A damping structure of a hard disk drive including a damping plate, attached to an upper surface of a cover member, to reduce a noise from an interior of the hard disk drive, and a resilient plate, provided to an edge of the cover member, to alleviate a shock applied to the cover member via resilient deformation of the resilient plate. The resilient plate is bent from the damping plate so as to be spaced apart from the upper surface of the cover member at a desired interval. The resilient plate is provided at a height higher than a protrusion formed along the edge of the cover member. The external shock applied to the cover member can be effectively alleviated, and the resilient plate may minimize a flaw that may be formed on the damping plate in the course of assembling the hard disk drive.
Claims23
A damping structure of a hard disk drive, including a base member and cover member, which enclose close a spindle motor to rotate a data storage disk and an actuator to move a read/write head to a predetermined position on the disk, the damping structure comprising:
- a damping plate, attached to an upper surface of the cover member, to reduce a noise from an interior of the hard disk drive;
- and
- a resilient plate, provided on the damping plate towards an edge of the cover member, to alleviate a shock applied to the cover member via resilient deformation of the resilient plate, the resilient plate being bent from the damping plate so as to be spaced apart from the upper surface of the cover member at a desired interval.
A damper of a disk drive, including a base member and cover member having an edge and an upper surface, the damper comprising:
- a damping plate, attached to the upper surface of the cover member;
- and
- a resilient plate, provided on a portion of the damping plate located near the edge of the cover member, to resiliently deform as a result of an impact on the disk drive, the resilient plate being bent upward from the damping plate so as to be spaced apart from the upper surface of the cover member at an interval that is sufficiently large such that the deformed resilient plate does not contact the cover member.
A damper of a disk drive, including a base member and cover member having an edge, sides, and an upper surface, the damper comprising:
- a damping plate, attached to the upper surface of the cover member;
- and
- a plurality of resilient plates, provided on a portion of the damping plate located near the sides of the cover member, to resiliently deform as a result of an impact on the disk drive, the resilient plate being bent upward from the damping plate so as to be spaced apart from the upper surface of the cover member at an interval that is sufficiently large such that the deformed resilient plate does not contact the cover member.
A damper of a disk drive, including a base member and cover member having an edge extending around the cover member, and an upper surface, the damper comprising:
- a damping plate, attached to the upper surface of the cover member;
- and
- a resilient plate, provided on a portion of the damping plate located near the edge of the cover member, to resiliently deform as a result of an impact on the disk drive, the resilient plate being bent upward from the damping plate so as to be spaced apart from the upper surface of the cover member at an interval that is sufficiently large such that the deformed resilient plate does not contact the cover member.
