Housing mechanism for receiving memory card

Abstract

A housing mechanism ( 8 ) includes a housing ( 1 ) and a defending element ( 3 ). The housing has a cavity ( 11 ), thereby defining a sidewall. The sidewall of the housing defines an opening ( 2 ) therethrough. The opening communicates with the cavity. The defending element is located at the opening, and includes a door pivotable for covering or uncovering the opening.

1 . A housing mechanism for a portable electronic device, the housing mechanism comprising: 
 a housing defining a cavity therein, including a sidewall with an opening defined therethrough, the opening communicating with the cavity, the opening being configured for allowing a memory card to insert into the cavity; and    a defending element located at the opening, and integrally forming a door pivotable between a covering position and an uncovering position for covering or uncovering the opening.    
   
   
       2 . The housing mechanism as claimed in  claim 1 , wherein the opening is substantially rectangular.  
   
   
       3 . The housing mechanism as claimed in  claim 1 , wherein the defending element is substantially a rectangular board.  
   
   
       4 . The housing mechanism as claimed in  claim 1 , wherein the size of the defending element is larger than that of the opening.  
   
   
       5 . The housing mechanism as claimed in  claim 1 , wherein the defending element further includes a frame, a first side of the door is integrally connected with the frame, and an opposite second side is rotatable about the first side of the door.  
   
   
       6 . The housing mechanism as claimed in  claim 5 , wherein the frame defines a cutout, the shape and size of the cutoutis substantially the same with that of the door.  
   
   
       7 . The housing mechanism as claimed in  claim 5 , wherein the frame is fixed to an inner side of the sidewall.  
   
   
       8 . The housing mechanism as claimed in  claim 5 , wherein the frame is fixed to the sidewall around the opening.  
   
   
       9 . The housing mechanism as claimed in  claim 5 , wherein the first side of the door defines a slit therethrough adjacent the frame.  
   
   
       10 . The housing mechanism as claimed in  claim 5 , wherein the defining element is made of elastic material, when the door is rotated toward the uncovering position, the joint portion of the door and the frame produces a resilient restoring force due to elastic deformation of the defining element itself, for loading the door toward the covering position.  
   
   
       11 . A housing mechanism for a portable electronic device, comprising: 
 a housing comprising a sidewall defining an opening for a memory card to insert therethrough;    a frame fixed to an inner side of the sidewall at the opening; and    a door pivotably attached to the frame for covering or uncovering the opening.    
   
   
       12 . The housing mechanism of  claim 10 , wherein the door is substantially rectangular, and is integrally extending from the frame.  
   
   
       13 . The housing mechanism of  claim 11 , wherein the door has a first long side integrally connected with the frame, and an opposite second long side and the other two short sides are separate from the frame.  
   
   
       14 . A housing mechanism for a portable electronic device, comprising: 
 a housing comprising a sidewall defining an opening for a memory card to insert therethrough; and    a defending element comprising a frame attached to the sidewall around the opening, and a door attached to the frame, the frame defining a cutout aligned with the opening, the door and the cutout having a substantially same shape and size, the door being pivotable for closing or opening the cutout.    
   
   
       15 . The housing mechanism as claimed in  claim 14 , wherein the size of the defending element is larger than that of the opening.  
   
   
       16 . The housing mechanism as claimed in  claim 14 , wherein the door has a first side integrally connected with the frame, and an opposite second side rotatable about the first side with respect to the frame, when the second side is rotated away from the frame, a joint portion of the door and the frame produces a resilient restoring force due to elastic deformation of the defining element itself, for loading the second side toward the frame.  
   
   
       17 . The housing mechanism as claimed in  claim 16 , wherein the joint portion defines at least one slit therethrough for increasing elasticity at the joint portion.
