Abstract

An exemplary housing mechanism (100) for an electronic device includes a front cover (10), a back cover (20), and an elastic sealing element (12). The front cover has a projecting edge (18) defined thereon. The back cover has a recessed edge (26) defined therein. The elastic sealing element has a tip portion (122) and is formed or sealed together with the front cover. The projecting edge of the front cover and the tip portion of the elastic sealing element are configured to be press fit into the recessed edge of the back cover.

Claims

1. A housing mechanism for an electronic device, comprising:

a front cover having a projecting edge defined thereon and a concave portion adjacent to the projecting edge;

a back cover having a grooved edge at least including two side surfaces defined therein; and

an elastic sealing element having a tip portion, the elastic sealing element being formed together with and sealingly attached to the front cover, and positioned in the concave portion of the front cover such that the projecting edge and tip portion are adjacent each other;

wherein the projecting edge of the front cover and the tip portion of the elastic sealing element are together configured to be press fit into the grooved edge of the back cover by;

(a) the projecting edge of the front cover contacting one side surface of the grooved edge; and

(b) the tip portion of the elastic sealing element contacting the other side surface of the grooved edge.

2. The housing mechanism as claimed in claim 1, wherein the grooved edge of the back cover has two side surfaces and a bottom surface.

3. The housing mechanism as claimed in claim 1, wherein the elastic sealing element is made of an elastomeric material.

4. The housing mechanism as claimed in claim 1, wherein the elastic sealing element is made of one of material chosen from the group consisting of rubber materials and thermoplastic urethanes (TPU).

5. The housing mechanism as claimed in claim 1, wherein a width of the projecting edge plus a width of the tip portion is slightly larger than that at an equivalent location within the grooved edge of the back cover.

6. The housing mechanism as claimed in claim 1, wherein the front cover and the back cover are made of a plastic material.

7. The housing mechanism as claimed in claim 1, wherein the front cover and the back cover are locked together by screws.
