Abstract

A fan structure includes a fan frame and a fan body. The fan frame includes two side plates, a first connecting plate, a buckling portion and a second connecting plate. The side plate includes a fan stopping plate, a first protruding portion and two second protruding portions. The first protruding portion and the second protruding portions are disposed on the fan stopping plate. The first connecting plate is connected with the fan stopping plates. The buckling portion is disposed on the first connecting plate. The second connecting plate connects with the fan stopping plates and the first connecting plate. The fan body is accommodated between the side plates. The fan body has some first and second recessed portions which accommodate the first protruding portions and the second protruding portions respectively. The side plates, the first connecting plate and the second connecting plate are integrally formed.

First claim

What is claimed is:

1. A fan structure, comprising: a fan frame, comprising: two side plates opposite to each other, each of the side plates comprising: a fan stopping plate; a first protruding portion disposed on the fan stopping plate; and two second protruding portions elastically disposed on the fan stopping plate; a first connecting plate connected with the fan stopping plates, the first connecting plate having a plurality of first hollow portions, each of the fan stopping plates having a plurality of second hollow portions, each of the plurality of first hollow portions and a corresponding one of the plurality of second hollow portions communicating with each other; at least one buckling portion disposed on the first connecting plate and configured to buckle with electric equipment; a power source and signal connecting portion disposed on the first connecting plate and configured to connect with a power source and signal device; and a second connecting plate connected with the fan stopping plates and the first connecting plate; and a plurality of first elastic structures, each of the first elastic structures comprising a first connecting portion and a corresponding second connecting portion connecting with each other, each of the first connecting portions connecting with the first connecting plate and being located at a respective one of the first hollow portions, each corresponding second connecting portion being located at a respective one of the corresponding second hollow portions, each of the second protruding portions being disposed on a respective one of the corresponding second connecting portions; and a fan body suitable to be accommodated between the side plates, the fan body having a plurality of first recessed portions and a plurality of second recessed portions, the first recessed portions being configured to accommodate the first protruding portions, the second recessed portions being configured to accommodate the second protruding portions, wherein the side plates, the first connecting plate and the second connecting plate are of an integrally-formed structure.

2. The fan structure of claim 1 , wherein the first connecting portion and the second connecting portion connect to form a “L” shape.

3. The fan structure of claim 1 , wherein each of the fan stopping plates has a plurality of third hollow portions, each of the third hollow portions extends along a circular locus to form a fan shape, the third hollow portions are evenly disposed around a center of the circular locus.

4. The fan structure of claim 3 , wherein the fan body has an entrance and an exit opposite to each other, the entrance and the exit respectively face to the fan stopping plates.

5. The fan structure of claim 1 , wherein the second connecting plate has a third recessed portion and a fourth recessed portion opposite to each other, the first connecting plate has a fifth recessed portion, the fifth recessed portion and the fourth recessed portion communicate with each other, and wherein the fan frame further comprises: a second elastic structure connected with the first connecting plate and at least partially located at the fifth recessed portion, and the buckling portion is disposed on a side of the second elastic structure away from the third recessed portion.

6. The fan structure of claim 5 , wherein the buckling portion is a hook structure.

7. The fan structure of claim 5 , wherein the fan stopping plates are substantially parallel with each other, the first connecting plate and the second connecting plate are substantially perpendicular to the fan stopping plates respectively.

8. The fan structure of claim 5 , wherein the first connecting plate and the second connecting plate are substantially perpendicular with other.
