Fan assembling structure and fan device having the same

Abstract

The disclosure provides a fan assembling structure and a fan device having the same. The fan comprises a frame having an upper board, a lower board and a circular connector, and blades disposed in the frame. The lower board comprises four side edges in sequential connection. A first fixing hole is at the first side edge, and a second fixing hole is at the upper board. The structure comprises an assembling board having a bottom plate and two parallel side plates. The bottom plate comprises a ventilating area. A through hole is defined at a first side of the ventilating area, and a hook is disposed on a second side of the ventilating area. And at least one protrusion extends inwardly from an inner side of at least one of the two parallel side plates, a guiding slot being formed between the protrusion and the bottom plate.

What is claimed is:

 wherein the assembling structure comprises an assembling board, which has a bottom plate and two parallel side plates vertical to the bottom plate, the bottom plate has a ventilating area, a through hole is defined at a first side of the ventilating area such that a fixing part can pass through the through hole, the first fixing hole at the first side edge of the lower board and the second fixing hole of the upper board, a hook is disposed on a second side of the ventilating area opposite to the first side, and   at least one protrusion extends inwardly from an inner side of at least one of the two parallel side plates between the first side and the second side of the ventilating area, and a guiding slot is formed between the protrusion and the bottom plate so as to slide the fan from the first side of the ventilating area to a predetermined fixing position on the assembling board.   
     
     
         2 . The assembling structure according to  claim 1 , wherein the bottom plate and the two parallel side plates are integrally formed. 
     
     
         3 . The assembling structure according to  claim 1 , wherein each of the two parallel side plates comprises the protrusion located at the inner side, and the two protrusions are staggered with each other. 
     
     
         4 . The assembling structure according to  claim 1 , wherein the protrusions are formed by punching the side plate. 
     
     
         5 . The assembling structure according to  claim 1 , wherein the distance between the protrusion and the bottom plate is equal to the thickness of the lower board of the frame. 
     
     
         6 . The assembling structure according to  claim 1 , wherein the hook is formed by punching the bottom plate. 
     
     
         7 . The assembling structure according to  claim 1 , wherein the height of the hook protruding from the bottom plate is equal to the thickness of the lower board, and the third side edge of the lower board is fixed by the hook. 
     
     
         8 . The assembling structure according to  claim 1 , wherein the height of the hook protruding from the bottom plate is equal to the distance between the upper surface of the upper board and the lower surface of the lower board, and the upper board and the third side edge of the lower board are fixed by the hook. 
     
     
         9 . The assembling structure according to  claim 1 , wherein the hook comprises a blocking portion which extends vertically from the bottom plate, and an elastic arm connected with the blocking portion, and a free end of the elastic arm is provided with a guiding surface inclining upwardly. 
     
     
         10 . A fan device, comprising a fan and a fan assembling structure, the fan comprising a frame and blades disposed in the frame, the frame comprising an upper board, a lower board and a circular connector connected between the upper board and the lower board, the lower board comprising a first side edge, a second side edge, a third side edge and a fourth side edge in sequential connection, a first fixing hole being defined at the first side edge of the lower board, and a second fixing hole corresponding to the first fixing hole being defined at the upper board,
 wherein the assembling structure comprises an assembling board, which has a bottom plate and two parallel side plates vertical to the bottom plate, the bottom plate has a ventilating area, a through hole is defined at a first side of the ventilating area such that a fixing part can pass through the through hole, the first fixing hole at the first side edge of the lower board and the second fixing hole of the upper board, a hook is disposed on a second side of the ventilating area opposite to the first side of the ventilating area, and   at least one protrusion extends inwardly from an inner side of at least one of the two parallel side plates between the first side and the second side of the ventilating area, and a guiding slot is formed between the protrusion and the bottom plate so as to slide the fan from the first side of the ventilating area to a predetermined fixing position on the assembling board.
