Protective Case for Portable Electronic Device

Abstract

A protective case for a portable electronic device includes a hard bottom plate, having at least one hole and a flange around a periphery thereof; a soft frame, connected to the bottom plate and having at least one through hole; an inner peripheral edge of the frame being provided with an engaging groove, the flange being engaged in the engaging groove, the frame cooperating with the bottom plate to form an accommodation space for receiving the portable electronic device, a face of the bottom plate, opposite to the accommodation space, cooperating with the frame to form an accommodation trough; a glass substrate, corresponding in shape to the accommodation trough; and a plastic film, disposed between the bottom plate and the glass substrate, the glass substrate and the plastic film being bonded together and disposed in the accommodation trough. Thereby, the glass substrate may increase the scratch resistance of the back of the protective case and may be provided with a color, a pattern or a character to enhance the quality of the protective case.

What is claimed is: 
     
         1 . A protective case for a portable electronic device, comprising:
 a bottom plate, made of a hard material, the bottom plate having at least one hole and a flange around a periphery thereof;   a frame, made of a soft material and connected to the bottom plate, the frame having at least one through hole, an inner peripheral edge of the frame being provided with an engaging groove, the flange being engaged in the engaging groove, the frame cooperating with the bottom plate to form an accommodation space, a face of the bottom plate, opposite to the accommodation space, cooperating with the frame to form an accommodation trough;   a glass substrate, corresponding in shape to the accommodation trough; and   a plastic film, disposed between the bottom plate and the glass substrate, a first adhesive layer being provided between the plastic film and the glass substrate, a second adhesive layer being provided between the plastic film and the bottom plate, the glass substrate and the plastic film being bonded together and disposed in the accommodation trough.   
     
     
         2 . The protective case as claimed in  claim 1 , wherein the glass substrate has at least one first perforation corresponding to the hole, and the plastic film has at least one second perforation corresponding to the hole. 
     
     
         3 . The protective case as claimed in  claim 2 , wherein the glass substrate has a height not beyond a depth of the accommodation trough after being attached. 
     
     
         4 . The protective case as claimed in  claim 3 , wherein four corners of the frame are each provided with a raised rib adjacent to the accommodation trough. 
     
     
         5 . The protective case as claimed in  claim 3 , wherein the first adhesive layer is an optical clear adhesive (OCA), and the second adhesive layer is a silicone rubber. 
     
     
         6 . The protective case as claimed in  claim 1 , wherein one of the glass substrate and the plastic film is provided with a color. 
     
     
         7 . The protective case as claimed in  claim 1 , wherein a surface of the plastic film is printed with a pattern, a line, a design, or a character. 
     
     
         8 . The protective case as claimed in  claim 1 , wherein an adhesive surface of the glass substrate is printed with a pattern, a line, a design, or a character.
