Fan module

Abstract

A fan module includes a fan, a bracket, a number of first fasteners, and a number of second fasteners. The bracket includes a base wall defining a number of locking holes. The fan includes a side plate defining a number of mounting holes. Each of the first fasteners includes a pole, a head portion, and a locking portion. A through hole is defined in the first fastener. A block protrudes on an inner surface of the through hole of the first fastener, aligning with the locking portion. Each of the second fasteners includes a shaft. The pole extends through the locking hole and the mounting hole of the fan. The shaft extends through the through hole of the first fastener to engage with the block, to deform the locking portion. Therefore the locking portion is locked to an inner surface of the side plate of the fan.

1 . A fan module, comprising:
 a bracket comprising a base wall defining a plurality of locking holes;   a fan comprising a side plate defining a plurality of mounting holes aligning with the locking holes of the base wall;   a plurality of first fasteners each comprising a pole, and a head and a fixing portion respectively formed from opposite ends of the pole, wherein a through hole is axially defined in each first fastener; a block protrudes on an inner surface of the fixing portion; and   a plurality of second fasteners each corresponding to one of the first fasteners, wherein each of the second fasteners comprises a shaft;   wherein the pole of each of the first fasteners extends through one of the locking holes of the base wall and the corresponding mounting hole of the fan; the fixing portion extends through and expose out of the mounting hole and is positioned at an inner side of the side plate of the fan, the shaft of a corresponding second fastener is inserted into the through hole of the first fastener; the shaft presses the block to deform the fixing portion out to form a stop portion protruding on the outer surface of the fixing portion, the stop portion resists against the inner side of the side plate to prevent the first fastener from disengaging from the corresponding mounting hole.   
     
     
         2 . The fan module as claimed in  claim 1 , further comprising a plurality of shockproof members respectively locked to the locking holes of the base wall, for resisting against the side plate of the fan, wherein each of the shockproof members axially defines a through hole for the pole of a first fastener extending through. 
     
     
         3 . The fan module as claimed in  claim 2 , wherein the shockproof members are made of a shockproof material. 
     
     
         4 . The fan module as claimed in  claim 2 , wherein a locking slot is defined in a circumference of each of the shockproof members, each of the locking holes comprises a large portion and a small portion, the shockproof members are inserted into the locking holes from the large portions, the shockproof members are then pushed to the small portions to be locked in the small portions. 
     
     
         5 . The fan module as claimed in  claim 1 , wherein a diameter of the shaft is fit for close contacting the inner sidewall bounding the through hole of the first fastener. 
     
     
         6 . The fan module as claimed in  claim 1 , wherein each of the second fasteners comprises a head formed from one end of the shaft, an annular receiving portion is defined in the head facing and around the shaft, for receiving the corresponding head of the first fastener. 
     
     
         7 . The fan module as claimed in  claim 1 , wherein a plurality of splits parallel to the axis direction of the first fastener is defined in the fixing portion of each first fastener. 
     
     
         8 . The fan module as claimed in  claim 1 , wherein the first fasteners are made of a resilient material. 
     
     
         9 . A fan module, comprising:
 a bracket comprising a base wall defining a plurality of locking holes;   a fan comprising a side plate defining a plurality of mounting holes aligning with the locking holes of the base wall;   a plurality of columnar sleeve-shaped first fasteners each extending through the corresponding locking hole of the base wall and the corresponding mounting hole of the fan, with one end of the each of the first fasteners extending through and expose out of the mounting hole of the fan; wherein a through hole is axially defined in the first fastener; and   a plurality of second fasteners each corresponding to each of the first fasteners, wherein each of the second fasteners comprises a shaft, the shaft is inserted into the through hole of the corresponding first fastener to expand the end of the first fastener to prevent the first fastener from disengaging from the corresponding mounting hole.   
     
     
         10 . The fan module as claimed in  claim 9 , further comprising a plurality of shockproof members respectively locked to the locking holes of the base wall, for resisting against the side plate of the fan, wherein each of the shockproof members defines a through hole for the corresponding first fastener extending through. 
     
     
         11 . The fan module as claimed in  claim 10 , wherein the shockproof members are made of a shockproof material. 
     
     
         12 . The fan module as claimed in  claim 10 , wherein a locking slot is defined in a circumference of each of the shockproof members, each of the locking holes comprises a large portion and a small portion, the shockproof members are inserted into the locking holes from the large portions, the shockproof members are then pushed to the small portions of the locking holes to be locked in the locking holes. 
     
     
         13 . The fan module as claimed in  claim 9 , wherein a diameter of the shaft is fit for close contacting the inner sidewall bounding the through hole of the first fastener. 
     
     
         14 . The fan module as claimed in  claim 9 , wherein the first fasteners are made of a resilient material.
