Fan positioning structure

Abstract

A fan positioning structure includes a base, a cover, and a fan. Through configuring a rotating shaft of the fan, one end of the fan presses against a stopping portion of the base, and the other end of the fan bears against a stopper of the cover, such that the fan is confined to stably rotating between the base and the cover.

1 . A fan positioning structure, comprising:
 a base, comprising a stopping portion;   a cover, fitted to the base, and comprising a stopper corresponding to the stopping portion; and   a fan, rotatably disposed between the base and the cover, and comprising a rotating shaft penetrating the fan;   wherein one end of the rotating shaft presses against the stopping portion, and the other end of the rotating shaft bears against the stopper, such that the fan is confined to rotating between the base and the cover.   
   
   
       2 . The fan positioning structure according to  claim 1 , wherein the stopper comprises a bump, and the bump is disposed on one side of the stopper facing the fan and presses against the rotating shaft of the fan. 
   
   
       3 . The fan positioning structure according to  claim 1 , wherein the cover further comprises a frame and a connecting rib, the frame is fitted to the base, and the connecting rib connects the frame with the stopper. 
   
   
       4 . The fan positioning structure according to  claim 3 , wherein the connecting rib is wave-shaped. 
   
   
       5 . The fan positioning structure according to  claim 1 , wherein the base further comprises a bearing and a stator, the bearing is disposed on one end of the base where the stopping portion is disposed, the stator is sleeved on the bearing, and the fan further comprises a rotor for electrically interacting with the stator. 
   
   
       6 . A fan positioning structure, comprising:
 a base, comprising a stopping portion;   a cover, fitted to the base, and comprising a stopper corresponding to the stopping portion; and   a fan, rotatably disposed between the base and the cover, and comprising an urging portion and a rotating shaft disposed on two opposite sides thereof;   wherein the urging portion bears against the stopper, and one end of the rotating shaft contrary to the fan presses against the stopping portion, such that the fan is confined to rotating between the base and the cover.   
   
   
       7 . The fan positioning structure according to  claim 6 , wherein the stopper comprises a bump, and the bump is disposed on one side of the stopper facing the fan and presses against the urging portion of the fan. 
   
   
       8 . The fan positioning structure according to  claim 6 , wherein the cover further comprises a frame and a connecting rib, the frame is fitted to the base, and the connecting rib connects the frame with the stopper. 
   
   
       9 . The fan positioning structure according to  claim 8 , wherein the connecting rib is wave-shaped. 
   
   
       10 . The fan positioning structure according to  claim 6 , wherein the base further comprises a bearing and a stator, the bearing is disposed on one end of the base where the stopping portion is disposed, the stator is sleeved on the bearing, and the fan further comprises a rotor for electrically interacting with the stator.
