## Abstract

A mounting mechanism is used to mount a fan to a chassis. The mounting mechanism includes parallel first and second guide rails fixed to the chassis, and a mounting bracket fixed to the fan. The fan is slidably sandwiched between the first and second guide rails. The mounting bracket comprises a securing tab detachably and selectively fixed to a position on the first guide rail.

## Claims

### Claim 1

A mounting mechanism to fix a fan to a chassis, the mounting mechanism comprising:
a first guide rail fixed to the chassis;
a second guide rail fixed to the chassis and parallel to the first guide rail, to sandwich the fan together with the first guide rail; and
a mounting bracket fixed to the fan and comprising a securing tab detachably and selectively fixed to a position on the first guide rail.

### Claim 2 (depends on 1)

The mounting mechanism of claim 1, wherein the first guide rail comprises a first fixing wall fixed to the chassis and a first abutting wall perpendicularly extending up from a side of the first fixing wall adjacent to the second guide rail, the second guide rail comprises a second fixing wall fixed to the chassis and a second abutting wall perpendicularly extending up from a side of the second fixing wall adjacent to the first guide rail, the first and second abutting walls corresponding abut against opposite sides of the fan.

### Claim 3 (depends on 2)

The mounting mechanism of claim 2, wherein the first guide rail further comprises a positioning wall perpendicularly extending from a top of the first abutting wall opposite to the second abutting wall to fix the securing tab of the mounting bracket.

### Claim 4 (depends on 3)

The mounting mechanism of claim 3, wherein a plurality of positioning holes is defined in the positioning wall, and arranged along a lengthwise direction of the first guide rail, the securing tab defines a fastening hole, a screw extends through the fastening hole and is selectively engaged in one of the positioning holes.

### Claim 5

A fan assembly mounted in a chassis, the fan assembly comprising:
a first guide rail fixed to the chassis;
a second guide rail fixed to the chassis, and parallel to the first guide rail;
a fan slidably sandwiched between the first and second guide rails, and comprising opposite end boards correspondingly abutting against the first and second guide rails; and
a mounting bracket fixed to the fan, and comprising a securing tab detachably and selectively fixed to a position on the first guide rail.

### Claim 6 (depends on 5)

The fan assembly of claim 5, wherein each of the end boards defines a plurality of mounting holes, the mounting bracket comprises a plate-shaped main body and a plurality of mounting tabs perpendicularly extending from a side of the main body, a column perpendicularly extends from each of the mounting tabs, the mounting tabs are placed between the end boards of the fan, each of the columns is engaged in one of the mounting holes of the fan.

### Claim 7 (depends on 5)

The fan assembly of claim 5, wherein the first guide rail comprises a first fixing wall fixed to the chassis and a first abutting wall perpendicularly extending up from a side of the first fixing wall, the second guide rail comprises a second fixing wall and a second abutting wall perpendicularly extending up from a side of the second fixing wall, the first and second abutting walls corresponding abut against the end boards of the fan.

### Claim 8 (depends on 7)

The fan assembly of claim 7, wherein a side of the first abutting wall opposite to the first fixing wall faces a side of the second abutting wall opposite to the second fixing wall.

### Claim 9 (depends on 7)

The fan assembly of claim 7, wherein the first guide rail further comprises a positioning wall perpendicularly extending from a top of the first abutting wall to fix the securing tab of the mounting bracket.

### Claim 10 (depends on 9)

The fan assembly of claim 9, wherein a plurality of positioning holes is defined in the positioning wall, and arranged along a lengthwise direction of the first guide rail, the securing tabs defines a fastening hole, a screw extends through the fastening hole and is selectively engaged in one of the positioning holes.
