Fan assembly structure

Abstract

A fan assembly structure is provided. The fan assembly structure comprises a fan, an air-flow guiding structure and a fixing component. The air-flow guiding structure has a plurality of air-flow guiding holes, a leaning portion and a plurality of first locking portions distributed on the leaning portion. The fixing component has a plurality of second locking portions. The fan is pivotally connected with the fixing component. The second locking portion is adapted to rotate by an angle with respect to the leaning portion to lock with the corresponding first locking portion. Thereby, the fan is disposed on the air-flow guiding structure by only the fixing component.

What is claimed is: 
     
         1 . A fan assembly structure, comprising:
 a fan;   an air-flow guiding structure, having a plurality of air-flow guiding holes, a leaning portion and a plurality of first locking portions, the plurality of air-flow guiding holes being distributed at a periphery of the leaning portion, and the plurality of first locking portions being distributed on the leaning portion; and   a fixing component, having a plurality of second locking portions and a bushing portion;   wherein the bushing portion is disposed on a central portion of the fan, the fan rotatably connects with the fixing component by the bushing portion, and the second locking portions correspond to the first locking portions respectively and rotate relative to the leaning portion by an angle to lock with the first locking portions, and thereby the fan is disposed on the air-flow guiding structure by the fixing component.   
     
     
         2 . The fan assembly structure as claimed in  claim 1 , wherein a rotating direction of each of the second locking portions rotating relative to the leaning portion is opposite to a rotation direction of the fan. 
     
     
         3 . The fan assembly structure as claimed in  claim 2 , wherein the air-flow guiding structure is disposed on a sidewall of a casing. 
     
     
         4 . The fan assembly structure as claimed in  claim 3 , wherein the casing has a plurality of wind-collecting plates disposed around a periphery of the air-flow guiding structure. 
     
     
         5 . The fan assembly structure as claimed in  claim 4 , wherein the air-flow guiding structure has a plurality of ribs disposed around the leaning portion to define the air-flow guiding holes, and the leaning portion connects with the casing by the ribs. 
     
     
         6 . The fan assembly structure as claimed in  claim 5 , wherein the fixing component further comprises a wiring groove extending from a periphery of the fixing component. 
     
     
         7 . The fan assembly structure as claimed in  claim 6 , wherein the first locking portions and the second locking portions are three first locking portions and three second locking portions respectively. 
     
     
         8 . The fan assembly structure as claimed in  claim 7 , wherein a connecting line between a center of the leaning portion, each of the first locking portions and the adjacent first locking portion forms an included angle of 120 degrees. 
     
     
         9 . The fan assembly structure as claimed in  claim 8 , wherein the fixing component has a plurality of locating holes. 
     
     
         10 . The fan assembly structure as claimed in  claim 9 , wherein each of the second locking portions is a protrusion formed on a surface of the fixing component, and the protrusion and the surface together define a gap. 
     
     
         11 . The fan assembly structure as claimed in  claim 10 , wherein the first locking portions are distributed at a periphery of the leaning portion and the second locking portions are distributed on the fixing component corresponding to each of the first locking portions respectively. 
     
     
         12 . The fan assembly structure as claimed in  claim 10 , wherein the first locking portions are distributed in a central region of the leaning portion and the second locking portions are distributed on the fixing component corresponding to each of the first locking portions respectively. 
     
     
         13 . The fan assembly structure as claimed in  claim 11 , wherein each of the first locking portions is a groove, and when the second locking portion is located at an end of the first locking portion and a locking surface of the groove is located in the gap, the fixing component rotates relative to the leaning portion, so that the second locking portion slides along the locking surface from the end of the first locking portion to the other end of the first locking portion. 
     
     
         14 . The fan assembly structure as claimed in  claim 12 , wherein each of the first locking portions is a groove having a hole formed on a locking surface of the groove, and when the second locking portion is located at an end of the first locking portion and the second locking portion passes through the hole to locate the locking surface of the groove into the gap, the fixing component rotates relative to the leaning portion, so that the second locking portion slides along the locking surface from the end of the first locking portion to the other end of the first locking portion.
