Fan vibration damping structure

Abstract

A fan vibration damping structure includes a main body and a stator assembly. The main body has a bearing cup protruding from one face of the main body. The stator assembly has a through hole, whereby the stator assembly is fitted around the bearing cup. An elastic body is disposed between the bearing cup and the stator assembly. The elastic body is able to effectively absorb the vibration of the main body.

What is claimed is: 
     
         1 . A fan vibration damping structure comprising:
 a main body having a bearing cup protruding from one face of the main body;   a stator assembly having a through hole, whereby the stator assembly is fitted around the bearing cup, an elastic body being disposed between the bearing cup and the stator assembly.   
     
     
         2 . The fan vibration damping structure as claimed in  claim 1 , wherein the elastic body is integrally formed with the bearing cup. 
     
     
         3 . The fan vibration damping structure as claimed in  claim 1 , wherein the bearing cup further has a first recess annularly formed on an outer circumference of the bearing cup corresponding to the stator assembly, the elastic body being disposed in the first recess and attached to the bearing cup and the stator assembly. 
     
     
         4 . The fan vibration damping structure as claimed in  claim 1 , wherein the elastic body is made of a material selected from a group consisting of rubber, plastic and foam material. 
     
     
         5 . The fan vibration damping structure as claimed in  claim 1 , wherein an inner wall face of the through hole of the stator assembly is formed with a second recess corresponding to the bearing cup, the elastic body being disposed in the second recess and attached to the bearing cup and the stator assembly. 
     
     
         6 . The fan vibration damping structure as claimed in  claim 1 , wherein the stator assembly includes multiple silicon steel sheets and multiple windings. 
     
     
         7 . The fan vibration damping structure as claimed in  claim 1 , wherein the bearing cup has a bearing hole and a receiving space in communication with the bearing hole.
