Fan vibration absorber device

Abstract

A fan vibration absorber device comprising: left side fans; right side fans; rectangular connecting frames of equal thickness affixed to front and rear side walls of the left and right fans respectively, and through holes are defined in four corners of each of the connecting frames; flexible pads, which are joined to the rectangular connecting frames of the left and right side fans; flexible pins, each of which have a neck portion of relatively small diameter and an insert end, the flexible pins respectively insert into connecting holes of the flexible pads and through holes of the left and right side fans, wherein the neck portions clamp position within the through holes. The present invention is applicable for use in host computer cases or power supply devices to effectively reduce transmission of vibrational torque of the fans, and lower noise output therefrom

1 . A fan vibration absorber device comprising: 
 at least more than one left side fan;    at least more than one right side fan;    rectangular connecting frames of equal thickness affixed to front and rear side walls of the left and right fans respectively, and through holes are defined in four corners of each of the connecting frames;    at least more than one flexible pad having hollow portions, and connecting holes are respectively defined in four corners positioned at outer sides of the hollow portions, the flexible pads are joined to the rectangular connecting frames of the left and right side fans;    flexible pins, each of which have a neck portion of relatively small diameter and an insert end, and the flexible pins respectively insert into the connecting holes of the flexible pads and the through holes of the left and right side fans; the neck portions clamp position within the through holes.    
   
   
       2 . The fan vibration absorber device according to  claim 1 , wherein the pads and the pins are fabricated from rubber material, and a protruding piece extends from one side of each of the pads.  
   
   
       3 . The fan vibration absorber device according to  claim 1 , wherein the front end of the neck portion of each of the pins assumes a tapered form.  
   
   
       4 . The fan vibration absorber device according to  claim 1 , wherein the flexible pads have concave surfaces that cover and join to outer surfaces of the connecting frames.  
   
   
       5 . The fan vibration absorber device according to  claim 1 , wherein each of the flexible pads has two or more of the hollow portions, a connecting member connects the adjacent hollow portions, and a through hole is defined in the connecting member; 
 two adjacent sides of the flexible pads respectively adjoin the pair of left side fans and the pair of right side fans;    the neck portion of each of the pins penetrates the through holes of the right side fans and the left side fans and the respective connecting holes of the pads.    
   
   
       6 . The fan vibration absorber device according to  claim 1 , wherein an inner surface of each of the protruding pieces respectively covers and joins to surfaces of the connecting frames of the left side fans and the right side fans.  
   
   
       7 . The fan vibration absorber device according to  claim 1 , wherein an assemblage of the left side fans and the right side fans, the pads and the pins is securely installed within a case that serves as an outer case for a power supply device.
