Abstract

Embodiments of the disclosure are directed to a transportation system for carrying servers. The transportation system includes a server rack and a shock-absorbing pallet. The shock-absorbing pallet is secured under the server rack and configured to move relative to the server rack to dampen vibration during transportation of the server rack. The shock-absorbing pallet includes a top cover, a bottom cover, one or more isolation devices, and one or supporting layers. The one or more isolation devices are disposed between the top cover and the bottom cover. Each isolation device includes a shock-absorbing component coupled to the top cover and the bottom cover. The one or more supporting layers are secured between the top cover and the bottom cover around the one or more isolation devices. The one or more supporting layers have a plurality of slots for guiding a pallet lifter therethrough.

First claim

What is claimed is:

1. A shock-absorbing pallet comprising:
a top cover;
a bottom cover;
a plurality of isolation devices disposed between the top cover and the bottom cover, each isolation device comprising a shock-absorbing component coupled to the top cover and the bottom cover, the shock-absorbing component having a suspension spring that compresses in a horizontal direction in response to an external force being applied in a vertical direction to the top cover; and
one or more supporting layers secured between the top cover and the bottom cover around the one or more isolation devices, the one or more supporting layers forming in-between a plurality of slots for guiding a pallet lifter therethrough.

2. The shock-absorbing pallet of claim 1 , wherein the shock-absorbing component further has a cylindrical body including:
a first stopper panel coupled to a first bracket, the first bracket attached to the top cover;
a second stopper panel opposite to the first stopper panel, the second stopper panel coupled to a second bracket that is attached to the bottom cover; and
a suspension piston disposed in the cylindrical body and configured to move between the first bracket and the second bracket.

3. The shock-absorbing pallet of claim 2 , wherein the suspension spring is disposed around the cylindrical body between the first stopper panel and the second stopper panel, wherein a displacement of the suspension piston causes the suspension spring to compress between the first stopper panel and the second stopper panel.

4. The shock-absorbing pallet of claim 1 , wherein the top cover and the bottom cover are formed from a thermally-insulated material.

5. The shock-absorbing pallet of claim 1 , wherein the top cover and the bottom cover are generally rectangular in shape.

6. The shock-absorbing pallet of claim 5 , wherein the plurality of isolation devices includes four isolation devices disposed adjacent to four corners of the shock-absorbing pallet.

7. The shock-absorbing pallet of claim 6 , wherein the shock-absorbing components of any two isolation devices along a length of the shock-absorbing pallet move towards each other.

8. The shock-absorbing pallet of claim 6 , wherein the shock-absorbing components of any two isolation devices along a breadth of the shock-absorbing pallet move in the same direction.

9. The shock-absorbing pallet of claim 5 , wherein the one or more supporting layers are disposed such that there are two slots along a length and another two slots along a breadth of the shock-absorbing pallet for guiding the pallet lifter along the length and the breadth respectively.

10. The shock-absorbing pallet of claim 1 , wherein the one or more isolation devices are disposed at or around a center of the shock-absorbing pallet to enable uniform force distribution.

11. The shock-absorbing pallet of claim 1 , wherein each of the one or more supporting layers are formed from an elastic material, an elastomeric material, or a foam material.

12. The shock-absorbing pallet of claim 1 , wherein the one or more supporting layers are distributed evenly from a center of the shock-absorbing pallet around the one or more isolation devices.

13. A transportation system for servers, the transportation system comprising:
a server rack; and
a shock-absorbing pallet secured under the server rack and configured to move relative to the server rack to dampen vibration during transportation of the server rack, the shock-absorbing pallet including:
a top cover;
a bottom cover;
a plurality of isolation devices disposed between the top cover and the bottom cover, each isolation device comprising a shock-absorbing component coupled to the top cover and the bottom cover, the shock-absorbing component having a suspension spring that compresses in a horizontal direction in response to an external force being applied in a vertical direction to the top cover, the top cover and the bottom cover extending along a length and a breadth that encompasses within its periphery all of the plurality of isolation devices; and
one or more supporting layers secured between the top cover and the bottom cover around the one or more isolation devices, the one or more supporting layers forming in-between a plurality of slots for guiding a pallet lifter therethrough.

14. The transportation system of claim 13 , wherein the shock-absorbing component further has a cylindrical body including:
a first stopper panel coupled to a first bracket, the first bracket attached to the top cover;
a second stopper panel opposite to the first stopper panel, the second stopper panel coupled to a second bracket that is attached to the bottom cover; and
a suspension piston disposed in the cylindrical body and configured to move between the first bracket and the second bracket.

15. The transportation system of claim 14 , wherein the suspension spring is disposed around the cylindrical body between the first stopper panel and the second stopper panel, wherein a displacement of the suspension piston causes the suspension spring to compress between the first stopper panel and the second stopper panel.

16. The transportation system of claim 13 , wherein the top cover and the bottom cover are formed from a thermally-insulated material.

17. The transportation system of claim 13 , wherein the shock-absorbing pallet has a length greater than a length of the server rack and the shock-absorbing pallet has a breadth greater than a breadth of the server rack.

18. The transportation system of claim 13 , wherein the one or more isolation devices are disposed at or around a center of the shock-absorbing pallet to enable uniform force distribution.

19. The transportation system of claim 13 , wherein each of the one or more supporting layers are formed from an elastic material, an elastomeric material, or a foam material.

20. The transportation system of claim 13 , wherein the one or more supporting layers are distributed evenly from a center of the shock-absorbing pallet around the one or more isolation devices.
