Hard disk bracket and electronic device employing the same
A hard disk bracket for fixing a hard disk defining a plurality of positioning holes in two opposite sidewalls thereof includes a chassis and two substantially parallel rows of fixing members projecting from the chassis, spaced from each other, and receiving the hard disk therebetween. Each row of the fixing portion includes at least resilient two limiting portions each including a positioning pin received in the corresponding positioning hole to fix the hard disk and at least one supporting portion including a supporting plate parallel to the chassis to support the hard disk. The at least two limiting portions align with the at least one supporting portion. A distance between the surface of the chassis and the positioning pin is greater than that between the surface of the chassis and the supporting plate.
1. A hard disk bracket for fixing a hard disk defining a plurality of positioning holes in two opposite sidewalls thereof, the hard disk bracket comprising: a chassis; and two substantially parallel rows of fixing members projecting from the chassis, spaced from each other, and receiving the hard disk therebetween, each of the two rows of the fixing members comprising at least two limiting portions each comprising a positioning pin received in the corresponding positioning hole of the hard disk to fix the hard disk and at least one supporting portion comprising a supporting plate parallel to the chassis to support the hard disk, wherein the at least two limiting portions align with the at least one supporting portion, and wherein the at least two limiting portions are resilient so that the positioning pins can be easily inserted into or removed from the corresponding positioning holes of the hard disk; wherein a distance between the chassis and the positioning pin is greater than that between the surface of the chassis and the supporting plate; and wherein the hard disk defines a plurality of recesses in a bottom wall thereof, and wherein the supporting plates each comprise positioning blocks projecting therefrom upwardly capable of inserted into corresponding recesses of the hard disk.
2. The hard disk bracket as claimed in claim 1 , further comprising a plurality of elastic elements respectively located between the limiting portions and the side walls of the hard disk to protect the hard disk from vibration.
3. The hard disk bracket as claimed in claim 1 , wherein in each row of the fixing members, at least one limiting portion and at least one aligned supporting portion is integrally formed.
4. The hard disk bracket as claimed in claim 3 , further comprising an inverted U-shaped slot surrounding the limiting portion, adapted to provide resilience permitting the hard disk to be positioned in the hard disk bracket.
5. The hard disk bracket as claimed in claim 1 , wherein the limiting portions are separated from the supporting portions.
6. The hard disk bracket as claimed in claim 1 , wherein the hard disk bracket is formed using an injection molded process.
7. An electronic device comprises: a hard disk defining a plurality of positioning holes in two opposite sidewalls thereof; and a hard disk bracket comprising: a chassis; and a plurality of fixing members projecting from the chassis corresponding to the two opposite sidewalls of the hard disk, and receiving the hard disk therebetween, each of the fixing members comprising a limiting portion that comprises a positioning pin received in the corresponding positioning hole of the sidewall of the hard disk to fix the hard disk and at least one supporting portion that comprises a supporting plate parallel to the chassis to support the hard disk, wherein the limiting portions are resilient so that the positioning pins can be easily inserted into or removed from the corresponding positioning holes of the hard disk, and wherein a distance between the chassis and the positioning pin is greater than that between the surface of the chassis and the supporting plate; wherein the hard disk defines a plurality of recesses in a bottom wall thereof, and the supporting plates each comprise positioning blocks projecting therefrom upwardly capable of inserted into corresponding recesses of the hard disk.
8. The electronic device as claimed in claim 7 , further comprising a plurality of elastic elements respectively located between the limiting portions and the side walls of the hard disk to protect the hard disk from vibration.
9. The electronic device as claimed in claim 7 , wherein each supporting portion surrounds each limiting portion with an inverted U-shaped slot defined therebetween to achieve the resilience of the limiting portion to permit the hard disk to be positioned in the hard disk bracket.
10. The electronic device as claimed in claim 7 , wherein the limiting portions are separated from the supporting portions.
11. The electronic device as claimed in claim 7 , wherein the hard disk bracket is formed using an injection molded process.
