Embedded special computer

Abstract

The invention discloses an embedded special computer, which comprises a case consisting of a case body with an opening on the top and a case cover matched with the case body. A bottom plate is arranged in the case body and a main board is inserted on the bottom plate. The embedded special computer is characterized in that a hard disk bracket is in rotary connection with the inner upper part of the case body and the case cover is matched with and buckled on the top of the case body to seal the case body. The embedded special computer has the advantages of convenient maintenance and disassembling, excellent sealing performance of case, tight connection between the main board and the bottom board and resistance to impact and shock.

Description

technical field [0001] The invention relates to a computer, in particular to an embedded special computer. Background technique [0002] Miniaturization is the development trend of embedded special computers, especially industrial computers. Miniaturization puts forward more compact requirements for the internal structure of computers. The hard disk of the existing industrial computer is installed in the middle of the case, which occupies the limited space inside the case, and because the hard disk is located in the middle of the case, it is inconvenient to maintain and disassemble the hard disk and the main board and expansion board below it; It is often necessary to work in a dusty and polluted environment. For some industrial computers that use a flip-type case cover, the case cover and the side of the case body are connected by a rotating shaft. There is a gap between them, the sealing of the chassis is poor, and the failure of the industrial computer is often caused by...

The hard disk of the existing industrial computer is installed in the middle of the case, which occupies the limited space inside the case, and because the hard disk is located in the middle of the case, it is inconvenient to maintain and disassemble the hard disk and the main board and expansion board below it; It is often necessary to work in a dusty and polluted environment. For some industrial computers that use a flip-type case cover, the case cover and the side of the case body are connected by a rotating shaft. There is a gap between them, the sealing of the chassis is poor, and the failure of the industrial computer is often caused by dust and pollution; in addition, the industrial computer usually works in a highly vibrating environment, and the connection between the main board and the bottom plate of the general industrial computer is repeated many times. It is easy to loose after vibration, which affects the normal use of the industrial computer
