Description
1, technical field
The utility model relates to the portable computer technical field, specifically a kind of portable double screen computing machine.
2, background technology
Flourish along with computer technology, computer application is penetrated into all trades and professions widely, as national defence, oil, building, traffic, geology etc.In these industries, computing machine has flowability, and applied environment is often very abominable again, and very high to security, the reliability requirement of computing machine, common business computer is difficult to meet the demands, and this has impelled the birth of reinforcing portable machine.Reinforce portable machine and rely on it to high applicability of environment and to the high reliability of information security, being applied in all trades and professions more and more widely gone.
Not long since, double screen shows still more rare usage of output, and the application of Double-Screen Display System also is confined to use two independently displays mostly, promptly compares, and can only be applied in the lower occasion of portable degree requirement.But, development along with the information-based progress of all trades and professions, the continuous drop of the universal and price display unit of bull output video card, more and more higher for fields such as public security, People's Armed Police, space flight, aviation, fire-fighting, People's Armed Police, military affairs to portable requirement, require Double-Screen Display System also to want Highgrade integration, in light weight, be easy to carry, shift, can also experience the advantage that double screen shows that output brings simultaneously.
At present, the structure of the Portable Reinforced Computer on the market is made up of input equipment, messaging device, memory device, output device, IO interface.Wherein liquid crystal display is the chief component of output device, shows the image of computing machine output, for the user provides information the most intuitively; IO interface is the general-purpose interface of standard, in order to connect the input-output device of standard.Present Portable Reinforced Computer adopts single screen to show mostly, computer operation person once can only browse an interface, when using distinct program, need between different program windows, frequently switch, be difficult to improve aspect the comfort of work efficiency and computer operation person's operation, also will outside machine body, connecting display even can realize the double screen demonstration; The standard I-O interface switching performance is comparatively general, is difficult to be applicable to fields such as the higher industry of environmental index, People's Armed Police, military affairs.
3, summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of portable double screen computing machine is provided.
The technical solution of the utility model realizes in the following manner, this portable double screen computing machine, comprise main frame and display screen, display screen comprises main screen and secondary screen, hinge connects between main screen and the secondary screen, main screen is connected with the main frame hinge, double nip double screen of expansion shows video card on the main frame, this video card converts the frequency division card that two paths of signals enters the road input two-way output of an expansion on main frame respectively separately to by signal converter, and two frequency division cards connect main screen, secondary screen respectively.Main screen and secondary screen and main screen and hinge between the main frame are the structures of upper hinge and the following hinge open-type hinge center fixed of separating, upper hinge, following hinge have pan, be installed with video signal cable in the pan, video signal cable connects main screen and frequency division card, secondary screen and another frequency division card, and upper hinge is with following hinge fastening and by two screw retention on the hinged cover.Be hinged with handle on the main frame of the side that main frame and main screen are hinged.
The utility model has the advantages that:
This Portable Reinforced double screen computing machine has two display screens, can not only move various programs, and when carrying out multi-job operation, computer operation person can browse two windows simultaneously, makes computer operation person's operation more convenient.Configuration aspects, lower open-type structure in the employing, the pan of hinge by wherein with the vision signal cable between main frame and secondary screen organically and compact linking together also combines main frame and secondary screen simultaneously, solved the problem of portable and quick transfer effectively effectively.
