Abstract

A hard disk mounting assembly includes a chassis (10), a first cage (20) mounted to the chassis, a hard disk drive(40) (HDD) and a second cage (60). The HDD defines a plurality of fixing openings (42). The first cage includes a plurality of mounting pillars (28) resilient connected with the cage and received in the fixing openings of the HDD at one end portion. The first cage further defines a pair of engaging apertures (34) at opposite sides thereof. The second cage has a base (62) and two connecting arms (68) depending from the base. the base forms a plurality of elastic fingers (66). The first cage is mounted to the chassis and the HDD is received in the first cage, the second cage hitches the first cage by the connecting arms with the elastic fingers pressing the HDD, thereby mounting the HDD to the chassis.

Claims

1. A hard disk mounting assembly comprising:

a chassis;

a hard disk drive (HDD);

a first cage attached to the chassis and receiving the HDD, the first cage comprising a bottom plate and two side panels extending from the bottom plate, each of the side panels defining an engaging aperture; and

a second cage comprising a base and two connecting arms extending from opposite sides of the base, the base forming a plurality of elastic fingers, each of the connecting arms forming a barb for being received in the corresponding engaging aperture of the first cage;

wherein the first cage is mounted to the chassis and the HDD is received in the first cage, the second cage hitches the first cage by the barbs with the elastic fingers pressing the HDD, thereby mounting the HDD to the chassis.

2. The hard disk mounting assembly as claimed in claim 1, wherein the bottom plate of the first cage forms a plurality of mounting holes, a resilient damper is squeezed in each mounting hole and receives a mounting pillar.

3. The hard disk mounting assembly as claimed in claim 2, wherein the mounting pillar comprises a circular portion and a mounting end extending from a lower face of the circular portion.

4. The hard disk mounting assembly as claimed in claim 3, wherein a bottom face of the HDD defines a plurality of fixing openings for receiving the mounting ends of the pillars.

5. The hard disk mounting assembly as claimed in claim 3, wherein an orienting end received in the resilient damper extends from a top face of each circular portion.

6. The hard disk mounting assembly as claimed in claim 1, wherein the chassis forms a plurality of L-shaped buckles and a convex orienting portion for mounting the first cage.

7. The hard disk mounting assembly as claimed in claim 6, wherein the convex orienting portion defines a screw hole at a top thereof.

8. The hard disk mounting assembly as claimed in claim 1, wherein the first cage defines a plurality of cutouts corresponding to the buckles of the chassis.

9. The hard disk mounting assembly as claimed in claim 8, wherein the bottom plate of the first cage defines mounting aperture corresponding to the screw hole of the chassis, and a bolt penetrates through the mounting aperture and received in the screw hole of the chassis, thereby mounting the first cage to the chassis.

10. A hard disk mounting assembly comprising:

a hard disk drive (HDD) defining a plurality of fixing openings;

a chassis;

a first cage comprising a bottom plate and two side panels extending from the bottom plate, each side panel defining an engaging aperture, the bottom plate defining a plurality of mounting holes, each of the mounting holes receiving a resilient damper, the damper receiving a mounting pillar engaging with the HDD in a corresponding fixing opening; and

a second cage comprising a base and two connecting arms extending from opposite sides of the base, the base forming a plurality of elastic fingers, each of the connecting arms forming a barb for being received in the corresponding engaging aperture of the first cage;

wherein the first cage is mounted to the chassis and the HDD is received in the first cage, the second cage bitches the first cage by the barbs with the elastic fingers pressing the HDD, thereby mounting the HDD to the chassis.

11. The hard disk mounting assembly as claimed in the claim 10, wherein the mounting pillar comprises a circular portion, the circular portion upwardly extends an orienting end from,a top face thereof and downwardly extends a mounting end from a bottom face thereof.

12. The hard disk mounting assembly as claimed in the claim 10, wherein the chassis forms a plurality of L-shaped buckles and a convex orienting portion for mounting the first cage to the chassis.

13. The hard disk mounting assembly as claimed in the claim 12, wherein the convex orienting portion defines a screw hole at a top face thereof.

14. The hard disk mounting assembly as claimed in the claim 12, wherein the first cage defines a plurality of cutouts corresponding to the buckles of the chassis.

15. The hard disk mounting assembly as claimed in the claim 14, wherein the first cage further defines a mounting aperture corresponding to the screw hole of the chassis, and a bolt penetrates trough the mounting aperture and received in the screw hole of the orienting portion, thereby mounting the first cage to the chassis.

16. A hard disk mounting assembly comprising:

a hard disk drive (HDD);

a chassis;

a fist cage attached to the chassis and receiving the HDD, the first cage comprising a pair of parallel side panels each of which defines an engaging aperture therein; and

a second cage together with the first cage enclosing the HDD, the second cage comprising a pair of parallel connecting arms each of which forms a resilient barb thereon, the barbs of the connecting arms being received into the corresponding engaging apertures of the side panels of the first cage thereby securing the second cage to the first cage.

17. The hard disk mounting assembly as claimed in claim 16, wherein the HDD defines a plurality of fixing openings, and a plurality of pillars each with an orienting end are formed on the first cage for engaging into the fixing openings, thereby positioning the HDD in the first cage.

18. The hard disk mounting assembly as claimed in claim 17, wherein the pillars are equipped with damper structures between the HDD and the first cage.

19. The hard disk mounting assembly as claimed in claim 18, wherein the second cage forms a plurality of elastic fingers for pressing the HDD while the second cage engaging to the first cage, and said damper structures provide a damper effect along a same direction as an exerted force, derived from the elastic fingers, is directed.

20. The hard disk mounting assembly as claimed in claim 19, wherein said first cage and said second cage are assembled to each other along a same direction as an exerted force, derived from the elastic fingers, is directed.
