HARD DISK DRIVE
A hard disk drive includes a base, a screw housing includes at least one screw hole wall formed with a screw hole, and provided at lateral sides of the base, and a shock-absorbing space formed between the base and at least a part among outer walls of the screw housing. The base is a structure to absorb at least a part of a shock due to external impact and/or vibration applied to an external structure to which the hard disk drive is mounted, such that a defect due to external shock and/or vibration can be decreased.
1 . A hard disk drive comprising:
a base;
a screw housing having at least one screw hole wall formed with a screw hole, and provided at lateral sides of the base; and
a shock-absorbing space formed between the base and at least a part among outer walls of the screw housing except the screw hole wall.
2 . The hard disk drive according to claim 1 , wherein
the screw hole wall is formed in two outer walls of the screw housing at positions exposed to an outside of the base, and
the shock-absorbing space is formed between the base and three outer walls among four outer walls of the screw housing.
3 . The hard disk drive according to claim 2 , wherein the shock-absorbing space includes at least a first space and a second space formed between the base and three outer walls among four outer walls of the screw housing that is coupled to the base in the form of a cantilever so that the first space and the second space of the shock-absorbing space continuously communicate with one another.
4 . The hard disk drive according to claim 3 , wherein the screw housing comprises:
a cantilever structure where a rear wall of the screw housing opposite to a lengthwise central axis of the base is coupled to the base.
5 . The hard disk drive according to claim 1 , wherein the shock-absorbing space is formed between the base and two outer walls among four outer walls of the screw housing.
6 . The hard disk drive according to claim 5 , wherein the screw housing comprises:
a double cantilever structure where two lateral walls of the screw housing are disposed transversely to a lengthwise central axis of the base and are coupled to the base.
7 . The hard disk drive according to claim 6 , further comprising:
a coupling wall to couple the two lateral walls of the screw housing with the base, and includes a cross-section inclined with respect to a top surface of the base.
8 . The hard disk drive according to claim 1 , wherein
the base and the screw housing are a single body, and
the shock-absorbing space is provided by a slot formed in at least one of the base and the screw housing.
9 . The hard disk drive according to claim 8 , wherein
the shock-absorbing space is provided by a slot formed in the base, and
the shock-absorbing space is filled with a damper material to absorb at least a part of a shock.
10 . The hard disk drive according to claim 1 , wherein the base and the screw housing are coupled to each other to form the shock-absorbing space.
11 . The hard disk drive according to claim 10 , wherein the base and the screw housing are formed of different materials from each other.
12 . A digital storage device mounting apparatus, comprising:
a base to mount a digital storage device; and
a screw housing having a plurality of sides and at least one screw hole wall, the screw housing mounted on a side of the base such that at least one of the plurality of sides of the screw housing are spaced from the side of the base.
13 . The apparatus of claim 12 , wherein the screw housing comprises:
a double cantilever structure having two lateral walls that are disposed transversely to a lengthwise central axis of the base and are coupled to the base.
14 . The apparatus of claim 13 , further comprising:
a coupling wall to couple the two lateral walls of the screw housing with the base and that includes an inclined cross-section.
15 . The apparatus of claim 12 , further comprising:
a damping material disposed between the base and the side of the screw housing.
16 . The apparatus of claim 12 , wherein the base and the screw housing are formed of different materials from one another.
17 . A hard disk drive assembly, comprising:
a base to support a digital storage device; and
a screw housing extending from the base and separated from side walls of the base to provide a shock-absorbing space with respect to the walls of the base, the screw housing including a screw hole extending therethrough.
18 . The hard disk drive assembly of claim 17 , wherein the shock-absorbing space is formed between the walls of the base and outer walls of the screw housing.
19 . The hard disk assembly of claim 17 , wherein the screw housing comprises:
a cantilever structure where a rear wall of the screw housing opposite to a lengthwise central axis of the base is coupled to the base.
20 . The hard disk assembly of claim 17 , wherein the shock-absorbing space includes at least a first space and a second space formed between the base and the screw housing that is coupled to the base in the form of a cantilever so that the first space and the second space of the shock-absorbing space continuously communicate with one another.
