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.

DETAILED DESCRIPTION
[0011] Referring to FIG. 1 and FIG. 2, an embodiment of a fan
module includes a bracket 20, a fan 40, a plurality of shockproof
members 50, a plurality of first fasteners 60, and a plurality of
second fasteners 70.
[0012] The bracket 20 includes a base wall 22. The base wall 22
defines a vent 221 defined in a center of the base wall 22, and
defines four locking holes 222 in four corners of the base wall 22.
Each locking hole 222 includes a large portion 223, and a small
portion 224 communicating with the large portion 223.
[0013] The fan 40 includes a side plate 42 defining four mounting
holes 422 in four corners.
[0014] Each shockproof member 50 is made of shockproof material,
such as rubber. The shockproof members 50 are columnar and each
axially defines a through hole 51. A locking slot 52 is defined in
the circumference of the shockproof member 50.
[0015] Referring to FIG. 3, each first fastener 60 is a columnar
sleeve and includes a pole 62, a head 64 formed from a first end of
the pole 62, and a fixing portion 68 formed from a second end of
the pole 62. A through hole 621 is axially defined in the first
fastener 60, through the head 64, the pole 62, and the fixing
portion 68. The outside diameter of the fixing portion 68 is the
same as the pole 62. The inside diameter of the fixing portion 68
becomes less from a first portion of the fixing portion 68 adjacent
to the pole 62 to a second portion of the fixing portion 68 away
from the pole 62, which forms an acute angle a between extension
lines of the inner surface and the outer surface of the fixing
portion 68 along the axis direction of the first fastener 60. An
annular and tapered block 682 is formed on an inner surface of the
fixing portion 68. A plurality of splits 684 is defined in the
fixing portion 68, parallel to the axis direction of the first
fastener 60. The first fasteners 60 are made of resilient material,
such as plastic or metal.
[0016] Each second fastener 70 includes a shaft 72 and a head 74
formed at one end of the shaft 72. An annular receiving portion 742
is defined in the head 74, around the shaft 72, as shown in FIG. 5.
The outside diameter of the shaft 72 is suitable for close contact
with the inner sidewall bounding the through hole 621 of the first
fastener 60.
[0017] Referring to FIG. 4 and FIG. 5, in assembly, the shockproof
members 50 are inserted into the corresponding locking holes 222
from the large portions 223. The shockproof members 50 are then
pushed to the small portions 224. Therefore the shockproof members
50 are locked in the locking holes 222 through the wall bounding
the small portions 224 engaging in the locking slots 52. The side
plate 42 is in close contact with the shockproof members 50, with
the blades of the fan 40 aligning with the vent 221. The mounting
holes 422 align with the corresponding through holes 51. The pole
62 extends through the corresponding through hole 51 and the
corresponding mounting hole 422. The fixing portion 68 extends out
of the mounting hole 422 and is positioned at an inside of the side
plate 42. A corresponding shaft 72 is inserted into the through
hole 621, until the head 64 is received in the receiving portion
742. The shaft 72 presses the block 682 to deform the fixing
portion 68 out to form a stop portion 686 protruding on the outer
surface of the fixing portion 68, which forms an acute angle .beta.
(approximately same as the acute angle .alpha.) between extension
lines of the inner surface and the outer surface of the fixing
portion 68 along the axis direction of the first fastener 60. The
stop portion 686 resists against the inner side of the side plate
42 to avoid the first fastener 60 releasing from the mounting hole
422. The shockproof members 50 are positioned between the side
plate 42 and the base wall 22. The splits 684 are used to add
elasticity of the fixing portion 68 to be easily deformed.
[0018] In disassembly, the shafts 72 are pulled from the through
holes 621. The fixing portions 68 are restored to make the first
fasteners 60 be easily released from the mounting holes 422.
[0019] In another embodiment, the shockproof members 50 are
unnecessary. The base wall 22 defines four through holes to allow
the first fasteners 60 extending through.
[0020] The fan module in this embodiment utilizes four first
fasteners 60 and four corresponding second fasteners 70 to mount
the fan 40 to the bracket 20, which is convenient. The shockproof
members 50 can absorb the shock of the fan 40.
[0021] Even though numerous characteristics and advantages of the
embodiments have been set forth in the foregoing description,
together with details of the structure and function of the
embodiments, the disclosure is illustrative only, and changes may
be made in detail, especially in the matters of shape, size, and
arrangement of parts within the principles of the present
disclosure to the full extent indicated by the broad general
meaning of the terms in which the appended claims are
expressed.
