Abstract
Disclosed are an upper casing of an outer casing of a handheld computer and a manufacturing method thereof. The upper casing is combined by magnesium aluminum alloy materials and plastics, and is made of high-quality magnesium aluminum alloy materials which are casted or pressed into a magnesium aluminum alloy panel with curved edges at the surrounding. After going through passivating treatment, the magnesium aluminum alloy panel is placed in a plastic die of the upper casing of the outer casing of the handheld computer to inject through a hot pressing injection machine, thereby enabling the periphery of the magnesium aluminum alloy panel to be stably combined with plastics to form a semi-finished product. The semi-finished product is manufactured into the upper casing of the outer casing of the handheld computer which is combined by the magnesium aluminum alloy materials and the plastics after scientific polishing and finishing. The upper casing of the outer casing of the handheld computer which is manufactured by combining the characteristics of the magnesium aluminum alloy materials and the plastics achieves the communication effect of pressure resistance, strong impact resistance, not being easy to deform, and not affecting wireless operation, meets the requirements of modern information society, overcomes shortages of non-pressure-resistance, non-wear-resistance and easy deformation of the outer casing of the plastic outer casing of the handheld computer, and also overcomes the shortage that the outer casing of the handheld computer manufactured by the integral magnesium aluminum alloy materials affects wireless operation.
Description
Technical field
The present invention relates to portable computer external and preparation method thereof, upper casing of the portable computer external that particularly a kind of magnesium-aluminium alloy material combines with plastics and preparation method thereof.
Background technology
Portable computer external is the upper casing of portable computer external especially, is bearing the important task of protecting display screen and internal electronic element thereof, so the shell that requires laptop computer upper casing especially must have crushing resistance, impact resistance is strong, big, the indeformable function of intensity.The shell of common laptop computer adopts plastic production, and the shell shortcoming of the laptop computer of plastic production is that crushing resistance, impact resistance are relatively poor, intensity difference, yielding.At present, the shell that utilizes magnesium-aluminium alloy material die casting or impact briquetting to make whole laptop computer is also arranged, but the shell shortcoming of the laptop computer that above-mentioned all-metal is made is that electromagnetic wave is had stronger shielding action, the communication effect when influencing the laptop computer radio operation.
Summary of the invention
The objective of the invention is at above-mentioned shortcoming, develop the upper casing of the portable computer external that a kind of magnesium-aluminium alloy material combines with plastics, adopt magnalium plate stamping or magnalium die casting to make the plate part of the upper casing of portable computer external, adopt the periphery of the upper casing of plastic production portable computer external.The upper casing crushing resistance of the portable computer external that magnesium-aluminium alloy material combines with plastics, impact resistance are strong, and intensity is big, indeformable, does not influence the communication effect of laptop computer radio operation, adapt to the requirement of advanced information society.
The object of the present invention is achieved like this:
1, punching press or die-casting magnalium latten
Select the high-quality magnesium-aluminium alloy material for use, by die casting or Sheet Metal Forming Technology, according to the shape and the specification of the upper casing of portable computer external, punching press or die-casting magnalium latten are that thickness is 0.4～1.2 millimeter, and the magnalium flat board on curved limit is arranged all around.
2, the magnalium planar surface is handled
Carry out Passivation Treatment through existing advanced technology above-mentioned magnalium is dull and stereotyped, with the antiseptic power that increases the magnalium flat board and with the adhesion of plastics.
3, injection moulding
The magnalium flat board of above-mentioned Passivation Treatment is placed in the mould of plastics of upper casing of portable computer external,, makes the periphery and the plastics strong bonded of magnalium flat board, become semi-manufacture by the injection moulding of hot pressing injection machine.
4, external coating
The semi-manufacture of the periphery of the magnalium flat board after the above-mentioned injection moulding and plastics strong bonded, make the upper casing of the dull and stereotyped portable computer external that combines with plastics of magnalium behind the polishing of process science, the external coating.
The present invention is in conjunction with the upper casing of the characteristic made portable computer external of magnalium and engineering plastics, reaches this product crushing resistance, impact resistance is strong, is not easy distortion, does not influence the communication effect of radio operation, adapts to the requirement of advanced information society.Solved not withstand voltage, not wear-resisting, the yielding shortcoming of laptop computer plastic casing, the portable computer external that has also solved whole magnesium-aluminium alloy material making influences the shortcoming of radio operation.
Description of drawings
Fig. 1 is that the dull and stereotyped master who combines with plastics of magnalium looked synoptic diagram before the upper casing of embodiment of the invention portable computer external was decorated;
Fig. 2 is the schematic side view of the upper casing of embodiment of the invention portable computer external.
