Reinforced computer mainboard based on Loongson 3A processor

Abstract

The invention discloses a reinforced computer mainboard based on a Loongson 3A processor. The reinforced computer mainboard comprises a protective cover and a bottom plate fixed at the bottom of the protective cover, an air inlet pipe arranged on the side wall of the protective cover and being of a spiral structure, a sealing assembly arranged on the surface of the bottom plate and used for sealing the protective cover, a conveying mechanism arranged on the outer side of the protective cover and used for discharging air, so that a sweeping mechanism sweeps a main board assembly in a reciprocating manner; two threads opposite in direction are arranged on the surface of a lead screw, so that a rotary drum can be rotated; when a stop lever makes contact with a first limiting block, the stop lever abuts against the threads, the lead screw drives a moving mechanism to operate, and movement of the moving mechanism is achieved. When the motor rotates to drive the lead screw to rotate and thestop lever makes contact with the second limiting block, the stop lever abuts against the threads, the stop lever can drive the sweeping mechanism to incline upwards, and therefore the sweeping mechanism cannot make contact with the main board assembly in the process that the lead screw drives the moving mechanism to move.

Description

Technical field [0001] The invention relates to a reinforced computer motherboard, in particular to a reinforced computer motherboard based on a Loongson 3A processor, belonging to the technical field of computers. Background technique [0002] The computer motherboard is installed in the chassis and is one of the most basic and important components of a microcomputer. The motherboard is generally a rectangular circuit board, on which the main circuit systems that make up the computer are installed, generally there are BIOS chips, I / O control chips, keyboard and panel control switch interfaces, indicator plugs, expansion slots, motherboards and plug-in cards. DC power supply connectors and other components. [0003] At present, in some areas of my country with heavy sandstorms, such as western or desert areas, computer motherboards are used in signal transmission equipment for signal processing and transmission. However, due to heavy sandstorms, it is easy to cause poor heat dissi...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the computer main board is used for signal sorting and transmission in the existing signal transmission equipment. However, due to the strong wind and sand, it is easy to cause poor heat dissipation performance of the main board, and it is easy to enter dust, which aggravates the problem of the main board. The mainboard inside many devices is covered by dust all year round, which causes the mainboard to dissipate heat slowly, causing the mainboard to burn out, and it is easy for the mainboard to be sent by the wind and sand for a long time, and the strong shaking will affect the signal transmission. problem, and propose a kind of reinforced computer motherboard based on Godson 3A processor
