Protective case for portable electronic device

Abstract

A protective case includes a housing defining a receptacle for accommodating an electronic device including a main body and a display fixed to the main body, a first buffer layer fixed in the receptacle, a cover releasably latched to the housing, and a second buffer layer fixed to the cover. The first buffer layer encloses the main body to protect the main body from damage when the electronic device is accommodated in the receptacle. When the cover is latched to the housing, the second buffer layer, the second buffer layer contacts with and protect the display from damage.

What is claimed is: 
     
         1 . A protective case used for protecting an electronic device including a main board and a display fixed to the main body, the protective case comprising:
 a housing defining a receptacle;   a first buffer layer fixed in the receptacle;   a cover latched to the housing;   a second buffer layer is fixed to the cover.;   wherein the cover and the housing cooperatively form a compartment therebetween to accommodate the electronic device such that the first buffer layer contacts with and protects the main body from damage, the second buffer layer contacts with and protects the display from damage.   
     
     
         2 . The protective case of  claim 1 , wherein a rib protruding from the first buffer layer and a groove defined in the cover, when the rib is accommodated in the groove, the rib is compressed by the cover to form a sealing element so the compartment is sealed by sealing element. 
     
     
         3 . The protective case of  claim 2 , wherein the first buffer layer includes a main section, and a side section protruding from and surrounding the main section; a flange protrudes from an outer surface of the side section and surrounding the side section; the rib protrudes from an surface of flange facing away from the main section. 
     
     
         4 . The protective case of  claim 3 , wherein the housing includes a main board, a peripheral wall protruding an peripheral edge of the main board and surrounding the main board; the main board and the peripheral wall cooperatively enclose the receptacle. 
     
     
         5 . The protective case of  claim 4 , wherein a plurality of first hooks protruding from peripheral wall, a plurality of second hooks protruding from the cover; each first hook is latched with one of the second hooks to latch the cover to the housing. 
     
     
         6 . The protective case of  claim 5 , wherein the cover includes an inner surface and a groove defined in the inner surface; the second buffer layer is fixed to the inner surface and surrounded by the groove. 
     
     
         7 . The protective case of  claim 1 , wherein the first buffer layer is made of resin or silicone. 
     
     
         8 . The protective case of  claim 1 , wherein the second buffer layer is made of a foam. 
     
     
         9 . A protective case, comprising:
 a housing defining a receptacle for accommodating an electronic device including a main body and a display fixed to the main body;   a first buffer layer fixed in the receptacle, the first buffer layer use for enclosing the main body to protect the main body from damage;   a cover releasably latched to the housing;   a second buffer layer fixed to the cover;   wherein when the cover is latched to the housing, the second buffer layer, the second buffer layer contacts with and protect the display from damage.   
     
     
         10 . The protective case of  claim 9 , wherein a rib protruding from the first buffer layer and a groove defined in the cover, when the rib is accommodated in the groove, the rib is compressed by the cover to seal a compartment formed between the cover and the housing. 
     
     
         11 . The protective case of  claim 10 , wherein the first buffer layer includes a main section, and a side section protruding from and surrounding the main section; a flange protrudes from an outer surface of the side section and surrounding the side section; the rib protrudes from an surface of flange facing away from the main section. 
     
     
         12 . The protective case of  claim 11 , wherein the housing includes a main board, a peripheral wall protruding a peripheral edge of the main board and surrounding the main board; the main board and the peripheral wall cooperatively enclose a receptacle. 
     
     
         13 . The protective case of  claim 12 , wherein a plurality of first hooks protruding from peripheral wall, a plurality of second hooks protruding from the cover; each first hook is latched with one of the second hooks to latch the cover to the housing. 
     
     
         14 . The protective case of  claim 13 , wherein the cover includes an inner surface and a groove defined in the inner surface; the second buffer layer is fixed to the inner surface and surrounded by the groove. 
     
     
         15 . The protective case of  claim 9 , wherein the first buffer layer is made of resin or silicone. 
     
     
         16 . The protective case of  claim 9 , wherein the second buffer layer is made of foam.
