Abstract

The utility model provides a restructural, expanded quick -witted case structure, including the structure frame and respectively with structure frame fixed connection's front panel, rear panel, engine case base and quick -witted roof board, the top of the both sides wall of structure frame is equipped with exposes the formula buckle, the bottom of structure frame is equipped with embedded draw -in groove. This machine case structure allows freely to assemble between a plurality of quick -witted casees to realize the arbitrary combination of functional module, practiced thrift design investment and resource consumption.

Description

A kind of restructural, expendable machine box structure
Technical field
The utility model relates to casing structure field, particularly relates to the restructural under a kind of complex electromagnetic environment, extendible electromagnetism interference, electromagnetic leakage cabinet equipment.
Background technology
Along with the development of avionics, the various electromagnetic interference (EMI) phenomenons in space are more and more serious, and traditional casing structure can not meet the demands.Meanwhile, in designing and employing process, various module needs to be installed to together solid and reliablely, and need take into account restructural and the extensibility of casing structure, to realize shortening structure design, Production Time, the effect of resource reasonable distribution.In existing technical scheme, most mode adopting all-in-onecase, namely isolate cabinet inside and cabinet outside by an all-in-onecase cover, realize electromagnetic screen, install fixing effect, each functional module is installed on cabinet inside by screw or other mounting meanss.For the functional module independent assortment occurred in R&D process, the situations such as functional module increase, minimizing can not adapt to very well, and therefore this mode is not suitable for cabinet restructural, extendible demand.In fact, restructural, extendible effect can be realized by the appropriate design to system chassis structure, but rare design so on the market.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of restructural, prolongable casing structure, can realize the independent assortment of a functional module in designing and employing process, saves design investment and resource consumption.
The technical scheme realizing the utility model object is as follows:
A kind of restructural, expendable machine box structure, comprise structural frames and the front panel be fixedly connected with structural frames respectively, rear panel, chassis base and cabinet top board, the top of the two side of described structural frames is provided with exposed buckle, and the bottom of the two side of described structural frames is provided with embedded draw-in groove.
Further, described front panel is provided with and is provided with for the interconnected connector of the printed board in the casing structure of upper and lower two equivalent strength for the connector of the external input and output of printed board of casing structure inside, rear panel.
Further, the exposed buckle of both sides, described top and cabinet top board are 90 degree of angles, and bottom described exposed buckle and top casing structure, embedded draw-in groove is mutually permanently connected.
Further, described chassis base and structural frames are integrated.
Further, the two side of described structural frames is heat radiation form of grooves.
Further, described exposed buckle and embedded draw-in groove are provided with and fixedly mount hole accordingly.
Further, the shielding cover board being installed on cabinet rear is also comprised.
Further, described shielding cover board is provided with louvre.
The beneficial effects of the utility model are: a kind of restructural that the utility model provides, expendable machine box structure allow freely to assemble between multiple cabinet, the combination in any of practical function module can be carried out conveniently by the quantity increasing or reduce cabinet, save design investment and resource consumption.
Accompanying drawing explanation
Fig. 1 is the utility model casing structure schematic diagram;
Fig. 2 is the assembling schematic diagram that multiple casing structure is combined into a cabinet;
Fig. 3 is the cabinet integral figure that multiple casing structure is combined into a cabinet;
Wherein, 1-exposed buckle; 2-embedded draw-in groove; 3-cabinet top board; 4-chassis base; 5-rear panel; 6-front panel.
Embodiment
Further illustrate the utility model below in conjunction with accompanying drawing how to realize.
As Figure 1-3, a kind of restructural, expendable machine box structure, comprise structural frames, be screwed the front panel 6, rear panel 5, cabinet top board 3 and the chassis base 4 that are connected respectively with structural frames, if any particular/special requirement, at cabinet top board 3, conductive seal rubber strip between chassis base 4 and structural frames, also can be used to seal;
In order to being fixedly connected with between upper and lower two casing structures, the top of structural frames two side is provided with exposed buckle 1, with cabinet top board 3 in 90 degree of angles, the bottom of structural frames two side is provided with embedded draw-in groove 2, exposed buckle 1 and embedded draw-in groove 2 are provided with mounting hole, and the width of embedded draw-in groove 2 and exposed buckle 1 and mounting hole should match, thus when adjacent two casing structures connect, between adjacent two cabinets, corresponding draw-in groove 2 can be locked with buckle 1, hole potential energy is aimed at thus is convenient to screw and fixes, also rocking between up-down structure is there will not be when mechanical vibration, the two side of structural frames all adopts heat radiation groove design and loss of weight.
The front panel 6 of casing structure is provided with the connector of the external input and output of printed board for casing structure inside, can externally input and output power supply and signal by External cable, and this connector meets EMC requirement, can prevent electromagnetic radiation, interference; The rear panel 5 of casing structure is also provided with for the interconnected connector of the printed board in the casing structure of upper and lower two equivalent strength, can be interconnected with other cabinets by Internal cable, thus interconnected between practical function module, this connector can select cheap, that volume is little connector.
In specific implementation process, cabinet is made up of several modular standard PC case structure, cabinet rear is provided with shielding cover board, be used for fixing multiple casing structure on the one hand, on the other hand can dust-proof, anti-electromagnetic radiation, raising antijamming capability, shielding cover board can arrange louvre by the requirement of electromagnetic screen, according to the actual requirements multiple required cabinet is fixed together, achieves the combination in any of functional module.In order to reduce cabinet integral weight and improve structural strength, casing structure frame adopts monoblock 2A12 aluminium alloy (H112 state), processes by CNC milling machine, and cabinet top board and cabinet cover plate adopt 2A12 aluminium alloy (T4 state).After casing structure machines, need first through surface conduction oxidation processes (Ct.Ocd), and then spray the anti-paint of sub-light black three (PVF), the ability such as anti-oxidant, anticorrosive of the cabinet of so just increase.
