Abstract

A housing of a handheld electronic device includes a front and a rear shell, a bottom cover, a cover body, and a battery cover. A bearing portion and a battery receiving room are formed above and below the backside of the rear shell. A waterproof structure comprises a main body gasket, a cover body gasket, and a battery cover gasket. The top and bottom ends of the main body gasket are connected to a top gasket and a bottom cover gasket. The main body gasket and the top gasket are embedded at the adjoining profile and the topside between the front and rear shells. The bottom cover gasket is embedded between the bottom side of the housing and the bottom cover. The cover body gasket is embedded between the cover body and the bearing portion. The battery cover gasket is embedded between the battery receiving room and the battery cover.

Claims

1. A waterproof structure of a handheld electronic device, a housing of said electronic device comprising a front shell, a rear shell, a bottom cover, a cover body, and a battery cover, a bearing portion and a battery receiving room being disposed above and below a backside of said rear shell, respectively, said waterproof structure comprising:

a main body gasket with a shape conformable with an adjoining profile between said front and rear shells, a top end and a bottom end of said main body gasket being connected to a top gasket and a bottom cover gasket, respectively, said main body gasket and said top gasket being embedded between adjoining positions and topsides of said front and rear shells, respectively, said bottom cover gasket being embedded between a bottom side of said housing and said bottom cover;

a cover body gasket embedded between said cover body and said bearing portion of said rear shell; and

a battery cover gasket embedded between said battery receiving room and said battery cover;

whereby said housing of said electronic device has the waterproof effect through the help of said main body gasket, said top gasket, said bottom cover gasket, said cover body gasket, and said battery cover gasket.

2. The waterproof structure of a handheld electronic device as claimed in claim 1, wherein grooves opposed to each other are disposed at the adjoining positions of said front and rear shells, grooves opposed to each other are also disposed at the topsides of said front and rear shells, grooves are also disposed at bottom sides of said front and rear shells, and said grooves are used for embedding of said main body gasket and said top gasket and said bottom cover gasket of said main body gasket.

3. The waterproof structure of a handheld electronic device as claimed in claim 2, wherein a groove is disposed at an adjoining position of said bottom cover and the bottom side of said housing, and said groove corresponds to the combination of said grooves at the bottom sides of said front and rear shells.

4. The waterproof structure of a handheld electronic device as claimed in claim 1, wherein a groove is disposed at a top edge of said bearing portion of said rear shell, a flange is disposed at a bottom edge of said cover body, and said cover body gasket is embedded between said groove and said flange.

5. The waterproof structure of a handheld electronic device as claimed in claim 1, wherein a groove is disposed at a rear edge of said battery receiving room of said rear shell, a flange is disposed at a position adjoining said battery cover, and said battery cover gasket is embedded between said groove and said flange.

6. The waterproof structure of a handheld electronic device as claimed in claim 1, wherein a plurality of projective ears are further disposed>

at said main body gasket, said projective ears have through-holes, and said through holes correspond to positioning post hole bodies between said front and rear shells.

7. The waterproof structure of a handheld electronic device as claimed in claim 6, wherein a plurality of projective ears are further disposed at said bottom cover gasket of said main body gasket, said projective ears have through holes, and said through holes correspond to bottom hole bodies at the bottom side of said front and rear shells and bottom cover hole bodies of said bottom cover.

8. The waterproof structure of a handheld electronic device as claimed in claim 1, wherein said main body gasket is of vertical type, and a top end and a bottom end of said main body gasket are connected to a horizontal type top gasket and a horizontal type bottom cover gasket, respectively.
