Abstract

A waterproof structure for a housing of a portable electronic apparatus comprises a cover and an elastic pad. The cover comprises a pivot portion, and the cover is connected to the housing via the pivot portion such that the cover is capable of rotating in relation to the housing. The elastic pad comprises at least one protrusion structure, and the at least one protrusion structure is capable of inserting into a waterproof groove on the housing corresponding to the protrusion structure. When the cover is rotated to close the housing, the cover is capable of compressing the elastic pad to form a seal between the at least one protrusion structure and the waterproof groove.

Claims

1. A waterproof structure for a housing of a portable electronic apparatus, the waterproof structure comprising:

a cover comprising a pivot portion, the cover being connected to the housing via the pivot portion such that the cover is capable of rotating in relation to the housing; and

an elastic pad comprising at least one protrusion structure capable of inserting into a waterproof groove on the housing corresponding to the protrusion structure;

wherein, when the cover is rotated to close the housing, the cover is capable of compressing the elastic pad to form a seal between the at least one protrusion structure and the waterproof groove.

2. The waterproof structure as claimed in claim 1, wherein the elastic pad further comprises at least one auxiliary protrusion structure, the height of the at least one auxiliary protrusion structure being lower than the height of the at least one protrusion structure.

3. The waterproof structure as claimed in claim 1, wherein the cover further comprises an exterior cover and an interior cover, the exterior cover being slidingly combined with the interior cover.

4. The waterproof structure as claimed in claim 3, wherein the exterior cover further comprises a fastening member corresponding to an auxiliary fastening member on the housing.

5. The waterproof structure as claimed in claim 1, wherein the cover further comprises a locking device for locking the cover.

6. The waterproof structure as claimed in claim 1, wherein the elastic pad further comprises a fastening structure for fastening the elastic pad on the housing or on the cover.

7. A portable electronic apparatus comprising:

a housing; and

at least one waterproof structure, the waterproof structure comprising;

a cover comprising a pivot portion, the cover being connected to the housing via the pivot portion such that the cover is capable of rotating in relation to the housing; and

an elastic pad comprising at least one protrusion structure capable of inserting into a waterproof groove on the housing corresponding to the protrusion structure;

wherein, when the cover is rotated to close the housing, the cover is capable of compressing the elastic pad to form a seal between the at least one protrusion structure and the waterproof groove.

8. The portable electronic apparatus as claimed in claim 7, wherein the elastic pad further comprises at least one auxiliary protrusion structure, the height of the at least one auxiliary protrusion structure being lower than the height of the at least one protrusion structure.

9. The portable electronic apparatus as claimed in claim 7, wherein the cover further comprises an exterior cover and an interior cover, the exterior cover being slidingly combined with the interior cover.

10. The portable electronic apparatus as claimed in claim 9, wherein the exterior cover further comprises a fastening member corresponding to an auxiliary fastening member on the housing.

11. The portable electronic apparatus as claimed in claim 7, wherein the cover further comprises a locking device for locking the cover.

12. The portable electronic apparatus as claimed in claim 7, wherein the elastic pad further comprises a fastening structure for fastening the elastic pad on the housing or on the pivot portion.

13. The portable electronic apparatus as claimed in claim 7, wherein the housing further comprises an upper housing, a lower housing, and a waterproof pad, the upper housing being combined with the lower housing, and the waterproof pad being disposed in the joint of the upper housing and the lower housing.

14. The portable electronic apparatus as claimed in claim 13, wherein the waterproof pad comprises at least one protrusion structure.

15. The portable electronic apparatus as claimed in claim 7, wherein the portable electronic apparatus is an ultra mobile personal computer.
