Abstract

A waterproof structure for a casing of an electronic device includes: a first casing member, having a first casing portion, a first side portion surrounding the first casing portion, and a first peg disposed in the first casing portion; a second casing member, having a second casing portion, a second side portion surrounding the second casing portion, and a second pegs disposed in the second casing portion and configured to be corresponsive to the first peg; a waterproof member, having a ring portion and a packing portion integrally coupled with each other, and the ring portion being surrounded continuously by the first and second side portions and clamped between the first and second side portions, and the packing portion being disposed between the first and second pegs; and plural locking elements, passing into the first and second pegs to combine with the first and second casing members respectively.

First claim

What is claimed is:

1. A waterproof structure for a casing of an electronic device, comprising:
a first casing member, having a first casing portion, a first side portion surrounding the periphery of the first casing portion, and a plurality of first pegs disposed in and protruded from the first casing portion;
a second casing member, assembled with the first casing member, and having a second casing portion, a second side portion surrounding the periphery of the second casing portion, a plurality of second pegs disposed in and protruded from the second casing portion, and configured to be corresponsive to the first pegs respectively;
a waterproof member, having a ring portion, and a plurality of packing portions formed by integrally coupling the ring portion, and the ring portion being surrounded continuously by the first and second side portions and clamped between the first and second side portions, and the packing portions being disposed between the first and second pegs respectively; and
a plurality of locking elements, passing into the first and second pegs to combine the first and second casing members,
wherein a first accommodating area and a second accommodating area are defined between the first and second casing members, and the waterproof member is accommodated in the first and second accommodating areas;
wherein the first and second accommodating areas have a first interference slot and a second interference slot respectively and concavely formed on the first and second side portions and disposed around the ring portion, and each of the first and second interference slots is recessed into a width greater than the corresponsive width of the ring portion, so that the ring portion deforms in a widthwise direction of each of the first and second interference slots when the first and second casing members are engaged with each other to compress the ring portion.

2. The waterproof structure for a casing of an electronic device according to claim 1 , wherein the first pegs are coupled to an inner side of the first side portion.

3. The waterproof structure for a casing of an electronic device according to claim 1 , wherein the second pegs are coupled to an inner side of the second side portion.

4. The waterproof structure for a casing of an electronic device according to claim 1 , wherein the waterproof member is made of a rubber material and integrally formed.

5. The waterproof structure for a casing of an electronic device according to claim 1 , wherein the packing portions are disposed at the internal periphery of the ring portion.

6. The waterproof structure for a casing of an electronic device according to claim 1 , wherein each of the packing portions has an outer sleeve and an inner sleeve, and the outer sleeve with an external diameter corresponsive to each first peg is sheathed on each respective first peg, and the inner sleeve is extended inwardly from the internal periphery of the outer sleeve.

7. The waterproof structure for a casing of an electronic device according to claim 6 , wherein each first peg has a tapered neck portion formed at an upper end of the first peg, and the inner sleeve having an external diameter corresponsive to the neck portion is sheathed on the neck portion.

8. The waterproof structure for a casing of an electronic device according to claim 6 , wherein the outer sleeve has a thickness greater than the thickness of the inner sleeve.
