Description

Computer host housing structure

Technical field

The utility model relates to a kind of computer host housing structure, and particularly relevant for a kind of computer host housing structure with electromagnetic screen (EMI Shielding) design.

Background technology

In recent years, the development of Information technology is progressive day by day, notebook computer (NB; Notebook Computer), therefore is subjected to a large amount of favors of user and day by day popularizes because easy to carry.Increasing occasion is arranged, go abroad such as and be in harmony public, go on business even personal work chamber, program design etc., all can be dependent on the use of notebook computer.And because the portability of notebook computer (NB), make that it must satisfy gently, thin, short, little requirement, yet, (the CPU of the central processing unit in the notebook computer (NB); Central Processing Unit), the weight of main elements such as motherboard, fan or hard disk, though, at present as far as possible towards minimizing development, there is no significantly room for improvement.Therefore, if can be towards the weight development that alleviates computer casing, the good method that alleviates notebook computer (NB) weight of can yet be regarded as.

Fig. 1 is the synoptic diagram of traditional notebook computer (NB).Notebook computer 100 has main frame 102, LCD screen 104 and rotating shaft 106 (Hinge).Main frame 102 is to see through rotating shaft 106 to articulate with LCD screen 104.General computer host housing mainly is made up of loam cake and lower cover, and loam cake and lower cover can take apart, so that maintenance action is made in main frame inside.Yet, the host housing of notebook computer (NB) 100 design now, it in order to bear the powerful torsion that is produced when rotating shaft is rotated, all adopts magnalium spare as support at rotating shaft 106 places usually.Therefore, make the weight of notebook computer (NB) increase, and can't meet compact requirement.On the other hand, be lighter material if desire changes the enclosure material of notebook computer (NB), can take into account the requirement of outer cover intensity again.So shell how to take into account notebook computer (NB) is in light weight, and the intensity that increases shell, real is the important topic of present notebook computer (NB) research and development.

In addition, traditional design of Electromagnetic Shielding is to be located at the following of main frame 102 to cover, and the mode that gives coating (water plating or vacuum splashing and plating) adds the last layer electrodeposited coating with as electromagnetic protection, yet, this mode have yield not good with the unequal problem of coating.

Summary of the invention

In view of this, this novel purpose is exactly in that a kind of computer shell structure with design of Electromagnetic Shielding is provided, under the prerequisite that does not increase computer volume and weight, the attaching aluminium foil layer in the loam cake of computer casing or under cover, not only can provide the effect of electromagnetic screen, and take into account the intensity of computer casing.

According to the purpose of this utility model, a kind of computer shell structure with design of Electromagnetic Shielding is proposed, it is applicable to notebook computer, and this computer casing comprises: loam cake, lower cover and electro-magnetic screen layer.Lower cover is to be buckled in loam cake below, and electro-magnetic screen layer is to be aluminium foil layer, and its can be located at lower cover or under cover.Wherein, above-mentioned aluminium foil layer can be attached at loam cake with respect to the lower cover place, and it is to be covered in loam cake fully; Or aluminium foil layer can be attached at lower cover with respect to the loam cake place, and it is for being covered in lower cover fully; Or aluminium foil layer can be attached at the below of lower cover, and it is covered in lower cover for part; In addition, this aluminium foil layer also can be attached at the top and the below of lower cover simultaneously.

Loam cake described in the utility model is preferably and is plastic material, and lower cover preferable also be plastic material.The plastic material that above-mentioned upper and lower cover adopted can comprise: ABS propylene-styrene multipolymer (ABS; Acrylonitrile-Butadiene-Styrene), the height polystyrene (HIPS that contends with; High ImpactPolystyrene) or polycarbonate (Polycarbonate) etc.

By computer shell structure described in the utility model, can attach aluminium foil layer in the loam cake of computer casing or cover down and provide under the situation of effectiveness, and under the prerequisite that does not increase computer volume and weight, also take into account the intensity of computer casing.
