Abstract
The utility model relates to a metal plastic compound outer shell for hand holding device. The utility model is characterized in that: inside surface of the pressed and molded metal shell body is compounded with a plastic layer which is formed by a layer of injection and is provided with an abnormal structure. A caking agent layer is arranged between the plastic layer and the metal shell body. The metal shell body can be made of titanium alloy, magnesium alloy or aluminum alloy. The plastic layer can be made of polythene or polypropylene. The utility model has the advantages that: varied complex abnormal structures can be formed on the inner wall of the shell body. The utility model has high intension, strong metal tactile impression, thin shell wall, beautiful appearance, good capability of damping and has strong screening function to the electromagnetic wave. The utility model is an ideal and new outer shell of hand holding device.
Description
The utility model relates to composite material, the metallo-plastic composite bed shell that particularly a kind of handheld device is used.
Existing hand-hold electronic equipments, as mobile phone, portable notebook computer etc., shell all is made of plastic, generally comprises chimeric housing and lid mutually.Because function needs, often there is the abnormally-structured of many complexity the housing inboard, as feather key, chute, positioning boss, hole slot, screw thread, hasp and hinge etc.Adopt plastic shaping to be easy to realize above-mentioned various labyrinth.But plastics also have distinct disadvantage, poor as weatherability, be easy to wear out, be easy to cracked and intensity low etc.In addition, the plastic casing wall is thicker, and volume is big, and the no metal-like in surface is attractive in appearance inadequately.And plastic casing is poor to electromagnetic wave shielding, and electromagnetic pollution may cause harmful effect to human brain.As adopt existing plate type metal composite, and as aluminium plastic composite material, can only suppress the housing of simple shape, can't form the abnormally-structured of various complexity, particularly phone housing in the housing inboard.
The purpose of this utility model is the above-mentioned deficiency that will overcome prior art, and for handheld device provides a kind of attractive in appearance, intensity is high, electromagnetic wave shielding is good metallo-plastic composite shell, and moulding complexity inside the shell is abnormally-structured.
Solution of the present utility model is: the metal shell inner surface of compression moulding be compounded with that one deck pressure injection forms with abnormally-structured plastic layer, between plastic layer and metal shell, adhesive layer is arranged.
The material of above-mentioned metal shell can be titanium alloy, magnesium alloy or aluminium alloy etc.
Above-mentioned plastic layer can be polyethylene or polypropylene plastics etc.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the partial sectional view of novel metal plastics composite bed shell.
Referring to accompanying drawing, the metal shell 1 of handheld device is to form with the metal sheet compacting, is compounded with the plastic layer 2 that one deck forms by pressure injection at housing 1 inner surface.On this plastic layer the abnormally-structured of various complexity can be set, as keyway 4, boss 5 and screw 6 etc.For plastic layer is combined with metal shell firmly, should help the adhesive layer 3 of plastics and metal composite at the two coating one deck.Seasonable metal of this binding agent and plastics all have caking property preferably.As the bonding bright commercially available epoxies glue of poly-second (third) alkene and aluminium alloy, with the bonding available phenolic aldehyde epoxy glue of titanium alloy etc.
As the metal sheet of metal shell 1 preferably titanium alloy, magnesium alloy or aluminium alloy etc.Its thickness is 0.2～0.8mm.Phone housing is made of the above-mentioned alloy sheets of 0.2～0.6mm.
As everyone knows, titanium is a kind of reactive metal, also is a kind of novel biological engineering material, has superior corrosion resistance.Magnesium alloy light weight, aluminium alloy have outstanding decorative effect.Three's intensity and decorative effect all are higher than plastics far away.And plastics have advantages such as light weight, good insulating, noise elimination be wear-resisting, and have good adhesive property and multiple barrier propterty.The utility model rolls into one the advantage of the two, thereby produces desirable metallo-plastic composite shell.
The technical process of making the metallic composite shell is, earlier pressing metal plates become the housing of different shape, after degreasing and thinning processing, is coated with the adhesive layer to be fit to, and places corresponding compression mod, adopts the method for pressure injection to apply with inner plastic.Can have the abnormally-structured of various complexity on this inner plastic.Can form like this in conjunction with firm, specious metallo-plastic composite bed.
With the titanium alloy sheet is example, also can carry out metal faced carving erosion, draw a design, literal, sign, again through degreasing, pickling, polishing, send into and carry out plasma nitridation process in the treatment trough, through flushing, be coated with the phenolic aldehyde epoxy glue after air-dry, secondary places transfer mould again, adopt plastic pressure injection technology, make metallo-plastic composite bed shell.
The advantage of the utility model metallo-plastic composite shell is the abnormal shape knot that can form in inner walls various complexity Structure, and have the intensity height, metal-like is strong, shell wall is thin, good looking appearance, damping property are good, electromagnetic wave shielding is done With strong advantage, and product easily recycles, and belongs to the health-care environment protection type product, thereby is outside the desirable Novel hand-held equipment Shell.
