Description

Technical Field

[0001] The utility model relates to the technical field of computers, in particular to a computer mainboard protection device. Background Art

[0002] The computer motherboard, also called the mainboard, is one of the most basic and important components of a computer. When a traditional computer motherboard is assembled with a mainframe case, bolts are mostly used to fix the motherboard to the mainframe case.

[0003] During the research and development, we found that the most common damage problem of the motherboard is that the motherboard bends after being used for a period of time. We summarized the reasons for the bending of the motherboard as follows: 1. The motherboard generates high temperature during operation and it is difficult to dissipate, resulting in deformation; 2. With the development of technology, existing graphics cards are designed to be heavier. After the graphics card is inserted into the motherboard, the end of the graphics card away from the motherboard will be suspended in the air, so the heavier graphics card will pull the motherboard and cause the motherboard to deform. In response to the above problems, we proposed a computer motherboard protection device. Utility Model Content

[0015] 1. The utility model sets a heat dissipation structure and a lifting structure, and uses a limiting structure to fix the mainboard in the main case. At this time, the back of the mainboard will contact with the thermally conductive silicone.
