Folding general standard case for electronic devices

Abstract

The invention provides a folding general case for electronic devices. The general case for the electronic devices which are LRUs (line replaceable units) can be used for various military and civil purposes, is applicable to various platform conditions and belongs to an MCU (modular concept unit) dimension series with characteristics of standardization, generalization, serialization and modularization. The technical scheme includes that the folding general case comprises a face plate (1), a top plate (2), a rear frame (3) and a bottom plate (4) which are longitudinally fixedly connected with one another by screw assemblies (7) to form a rectangular case frame, left and right side doors (5 and 6) which can be folded and unfolded are mounted on two side surfaces of the rear frame by rotary shaft and screw combinations (8) in a mirror symmetry manner, function modules I and IV can be mounted on the left and right side doors, function modules II and III can be mounted between the top plate and the bottom plate, and an interface module V can be mounted in the rear frame of the case; environmental control cooling air is filled into the case from air inlets (16) at the bottom of the case and is exhausted from air outlets (17) on the top of the case; and a metal wire shielding net assembly (18) is mounted on the inner side surface of an air outlet region of the top plate of the case.

Description

technical field [0001] The invention relates to a universal standard case mainly used for aviation and communication electronic equipment. Background technique [0002] The electronic equipment chassis is a basic structure that reasonably assembles various electronic components, components, modules and mechanical parts inside the equipment into an organic whole to protect it from various complex environmental influences and interferences and ensure the realization of electrical performance. As a modern high-tech product, the electronic equipment case is no longer a simple concept of equipment casing and mechanical installation support, but a comprehensive technology that reflects the overall design concept of electronic equipment as the basic design content to meet the equipment function and use environment requirements. Foreign developed countries, especially Europe and the United States, have long implemented the standardization and serialization design of military and civ...

AI Technical Summary

Problems solved by technology

The specific manifestations are: the size and installation interface of these chassis are designed according to the specific equipment and installation requirements, and do not meet the standard chassis requirements of the MCU size series stipulated in the HB7390-96, ARINC600 specifications and other standards; the chassis design is closely integrated with the internal circuits and modules, and the chassis and circuit modules are not independent, and do not meet the requirements of generalization and combination; the chassis only has a single size specification, and has not been serialized; the real folding and open chassis structure has not been realized, and the module installation, use, and maintenance performance are poor ;The chassis is mainly aimed at civilian products, and its structural rigidity, electromagnetic shielding performance, and environmental adaptability are not suitable for the harsh requirements of military, airborne and other users and platforms on the chassis.
