Description

TECHNICAL FIELD

[0001] The application belongs to the field of embedded technology, and relates to an embedded computer case fixing device and an operation method. BACKGROUND

[0002] With the rapid development of aerospace equipment, as a core device, an embedded computer internally integrates a high-performance processor, a large-capacity memory and a high-speed storage device, and the structural design of the case of the embedded computer directly affects the reliability, maintenance convenience and environmental adaptability of the equipment. A traditional embedded computer case generally adopts a fixed mounting structure, and the core architecture is composed of a case body, an internal fixing plate and external fasteners. The case body is fixed in an equipment rack, a control cabinet or an embedded installation space through screws. However, the traditional structure exposes the following core technical problems in long-term application:

[0003] The internal hardware of the traditional case is fixed to the bottom plate and the side plate of the case body through screws or buckles. When it is necessary to replace components or troubleshoot faults, the external fixing screws of the case are first removed, and then the internal fixing plates are disassembled layer by layer. The operation process is complicated. For a compact case with high integration, cables are dense and the space is small. The disassembly process is easy to cause cable pulling or interface loosening. The time consumption of single maintenance is usually more than half an hour. Especially in the industrial control scene, the equipment needs to be continuously operated for one day. The maintenance cost is extremely high when the equipment is stopped. The traditional structure is difficult to meet the rapid maintenance demand. Moreover, there is a lack of buffer structure between the internal hardware of the case and the case body. Displacement is easy to occur due to impact during transportation or handling, causing damage to components. SUMMARY
