Abstract
An energy dissipative element (24) protects hard disk drives (22, 72, 92) from shocks and vibrations. A closed elastic envelope (48) houses a body of open cell foam (54), a volume of viscous liquid (56), and a compressible gas (64). Under compression or expansion of the foam (54), viscous liquid (56) flows through cell orifices and thereby dissipates energy resulting from external force applied against the elastic wall (48). The energy dissipative elements (24) are applied between a disk drive housing (22) and an outer case (26) to create a ruggedized portable disk drive module (20).
Claims8
A host module assembly for protecting a hosted device from shock and vibration, comprising:
- a case comprising a major upper case surface and a major lower case surface, configured with at least one external corner, and adapted to receive a hosted device within said case and to receive at least one damper against shock between the hosted device and the case;
- a hosted device located within the case;
- at least one damper against shock located between said hosted device and the case;
- and
- at least one bumper formed of elastomer material and engaged with said at least one corner, wherein said bumper comprises an upper bumper surface extending above said upper case surface and a lower bumper surface extending below said lower case surface, wherein one of upper or lower bumper surfaces defines a boss and the other of said upper or lower bumper surfaces defines a boss recess.
A host module assembly for protecting a hosted device from shock and vibration, comprising:
- a case formed of a top portion defining a top wall, a bottom portion defining a bottom wall, and a sidewall comprising an external corner, wherein said external corner includes a fastener mount formed of a part of said top portion and a part of said bottom portion and carrying a fastener that attaches together the top portion and bottom portion, and wherein said case is adapted to receive a hosted device within the case and is adapted to receive a shock damper between the hosted device and the case;
- a hosted device located within the case;
- a shock damper located between said hosted device and the case;
- and
- a resilient bumper engaged over said fastener mount and covering said fastener, wherein said resilient bumper is configured with a top face that extends above said top wall and a bottom face that extends below said bottom wall, and wherein one of said top and bottom faces defines a boss and the other of said top and bottom faces defines a recess shaped similarly to said boss.
