Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention can be embodied in many different forms than those herein described and many modifications may be made by one skilled in the art without departing from the spirit and scope of the invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1 to 3, a fan module 100 includes a fan fixing device 200 and a fan 30 fixed on the fan fixing device 200. The fan fixing device 200 includes a case side plate 10 and a fixing base 20 fixed on the case side plate 10. The fixing seat 20 is provided with a groove 11 for accommodating the fan 30, and a predetermined distance is formed between the bottom of the groove 11 and the case side plate 10. An elastic element 110 is arranged in the groove 11, and the fan 30 is fixed on the fixed seat 20 through the elastic element 110.

The elastic element 110 includes a positioning post 111 and an elastic hook 112. The positioning post 111 and the elastic hook 112 are both located at the edge of the groove 11. The fan 30 is fixed on the fixing base 20 through the positioning column 111 and the elastic hook 112.

The groove 11 is of a similar rectangular structure. The positioning posts 111 are located at the corners of the groove 11, and the elastic hooks 112 are located at two sides of the edge of the groove 11.

The fixing base 20 is a trapezoidal table. The bottom surface of the trapezoid table is fixed on the case side plate 10, and the top surface of the trapezoid table is provided with the groove 11.

The shape and size of the fan 30 are not limited as long as the fan can be fixed on the fixing base 20. Since the fixing base 20 is higher than the case side plate 10, the fan 30 has a predetermined distance with respect to the case side plate 10, so that the effect of fixing the fans 30 of different shapes and sizes can be achieved.

The shape of the recess 11 matches the profile of the fan 30. And the size of the fan 30 is larger than that of the recess 11.

The case side plate 10 is provided with a first through hole 22. The fixing seat 20 is provided with a protrusion 12 matched with the first through hole, and the fixing seat 20 is fixed on the case side plate 10 through the first through hole 22 and the protrusion 12.
