Protective case having detachable impact absorbers for a portable electronic device

Abstract

Provided is a protective case that can be installed with different replaceable impact absorbers according to various impact situations. The protective case has a housing and multiple impact absorbers. The housing has multiple corners, multiple receiving parts protruding from the corners, and a cavity to set up a portable electronic device. The impact absorbers are detachably mounted onto the receiving parts through multiple connection parts, and each impact absorber has a resilience ratio more than 40%. Various impact absorbers with different protection capabilities (e.g., impact absorbers with different thickness and resilience ratios) or different designs can be easily replaced and installed onto the common housing according to different impact situations or occasions, thereby the protective case can appropriately protect the portable electronic device.

What is claimed is: 
     
         1 . A protective case having detachable impact absorbers for a portable electronic device, comprising:
 a housing having:
 multiple sidewalls connected with each other to form multiple corners; 
 a cavity defined by the sidewalls; and 
 multiple receiving parts each respectively formed protruding from the corners; and 
   multiple impact absorbers each respectively and detachably mounted onto the receiving parts through multiple connection parts, wherein the connection parts are each respectively formed in the impact absorbers and cap respectively around the receiving parts.   
     
     
         2 . The protective case as claimed in  claim 1 , wherein a length of each receiving part capped within a corresponding connection part is not less than ½ of a total length of each receiving part. 
     
     
         3 . The protective case as claimed in  claim 1 , wherein at least two of the impact absorbers protrude relative to each sidewall of the housing. 
     
     
         4 . The protective case as claimed in  claim 1 , wherein the housing has a bottom wall jointed to the sidewalls, and the cavity are defined by the sidewalls and the bottom wall. 
     
     
         5 . The protective case as claimed in  claim 4 , wherein at least two of the impact absorbers protrude relative to the bottom wall of the housing. 
     
     
         6 . The protective case as claimed in  claim 1 , wherein the housing has a hardness equal to a hardness of each of the impact absorbers. 
     
     
         7 . The protective case as claimed in  claim 1 , wherein the housing has a hardness higher than a hardness of each of the impact absorbers. 
     
     
         8 . The protective case as claimed in  claim 1 , wherein the impact absorbers each have a resilience ratio more than 40%. 
     
     
         9 . The protective case as claimed in  claim 2 , wherein the impact absorbers each have a resilience ratio more than 40%. 
     
     
         10 . The protective case as claimed in  claim 7 , wherein the impact absorbers each have a resilience ratio more than 40%. 
     
     
         11 . The protective case as claimed in  claim 1 , wherein the receiving parts of the housing are formed in spherical shapes. 
     
     
         12 . The protective case as claimed in  claim 1 , wherein the receiving parts of the housing are formed in conical shapes and tapered towards the corners of the housing. 
     
     
         13 . The protective case as claimed in  claim 1 , wherein the receiving parts of the housing are formed in columnar shapes. 
     
     
         14 . The protective case as claimed in  claim 11 , wherein the connection parts have shapes complementary to shapes of the receiving parts. 
     
     
         15 . The protective case as claimed in  claim 12 , wherein the connection parts have shapes complementary to shapes of the receiving parts. 
     
     
         16 . The protective case as claimed in  claim 13 , wherein the connection parts have shapes complementary to shapes of the receiving parts. 
     
     
         17 . The protective case as claimed in  claim 1 , wherein the housing has a cutout formed in one of the sidewalls of the housing. 
     
     
         18 . The protective case as claimed in  claim 4 , wherein the housing has a cutout formed in the bottom wall of the housing. 
     
     
         19 . The protective case as claimed in  claim 1 , wherein the impact absorbers are made of a material selected from the group consisting of: polyurethane, vulcanized polybutadiene, and natural rubber.
