Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1 to Fig. 3, the large-size ultra-thin ultra-narrow casing that the embodiment of the present invention provides comprises a metal shell 10 and the plastic construction part 20 mutually bonding with described metal shell 10.Mutually bonding by bonding agent 30 between described metal shell 10 with described plastic construction part 20.The large-size ultra-thin ultra-narrow casing that the embodiment of the present invention provides can be the large-size ultra-thin ultra-narrow casing of the consumer electronics products such as television set.
Described metal shell 10 thickness is 0.5-1.5mm, and material used can be 5052 aluminium alloys or corrosion resistant plate.Described metal shell 10 back side is coated with bonding agent 30 by the mode of spraying or is scribbled bonding agent 30 by the mode of point gum machine point glue.Described bonding agent 30 is nanometer bonding agent.A bending part 11 is formed in the outer rim of casing after the punching press of described metal shell 10.The outer surface of described metal shell 10 can carry out the surface treatments such as anodic oxidation, wire drawing, silk-screen, realizes different appearance, strengthens the appearance and modeling expressive force of casing.
Described plastic construction part 20 is in strip structure, and it is formed with some the first spaced grooves 22 on bonding plane 21.Described first groove 22 when bonding agent 30 is in high temperature melting or is softening, for storing bonding agent 30.The surface 24 opposing with bonding plane 21 of described plastic construction part 20 has protruded out stud 23, for assembling with other parts (parts such as, on display screen).Described plastic construction part 20 has buffering metal and the plastic cement buffer structure expanded with heat and contract with cold at different temperatures.In the present embodiment, described plastic construction part 20 at certain length (such as, 150-250mm), be provided with the second groove 25 on the apparent surface 24 of bonding plane 21, described second groove 25 has been buffering metal and the plastic cement buffer structure expanded with heat and contract with cold at different temperatures.The degree of depth of described second groove 25 is 1-1.5mm.Replace the second groove 25, described plastic construction part 20 can arrange a gap in certain length (such as, 150-250mm), and plastic construction part 20 is disconnected herein, to cushion metal and plastic cement expanding with heat and contract with cold at different temperatures.
Described plastic construction part 20 material used can be PC(Merlon) with ABS(acrylonitrile-butadiene-styrene copolymer) mixture, PBT(polybutylene terephthalate (PBT)), PC and PF(phenolic resins), or TPU(TPUE rubber) etc. there is plasticity material make.
Please refer to Fig. 4 and Fig. 8, the manufacturing step of described large-size ultra-thin ultra-narrow casing is as follows:
1, one tabular metal shell is provided, forms bending part 11 and body 12 by impact style in the edge of described metal shell 10.Described tabular metal shell forms by hardware dies manufacture.For ensureing to obtain the good metal shell of dimensional accuracy, better, the lower-cost aluminum alloy materials of preferred processing characteristics.
2, on the back side of the body 12 of metal shell, bonding agent 30 is scribbled.Described bonding agent 30 environmentally temperature, humidity condition, after natural air drying 3.5-4 hour, used in about 6-7 days.In the present embodiment, described bonding agent 30 is coated in the part at the back side of body 12 and bending part 11, and in other embodiments, described bonding agent 30 only can be coated in the back side of body 12.
3, the metal shell 10 being stained with bonding agent 30 is put into an injection mold, plastic construction part 20 described in the back side injection mo(u)lding of metal shell 10.Described injection mold designs according to metal shell 10 and plastic construction part 20 integrated structure design part feature.
4, surface treatment is carried out to metal shell 10, according to appearance characteristics and the designing requirement of product, by relevant LOGO, word, pattern and decorative content silk-screen in the front of metal shell 10, by carrying out the process such as wiping, cleaning to metal shell 10 surface, the appearance required for acquisition.
In the present embodiment, at the back side of metal shell 10 direct injection mo(u)lding plastic construction part 20, metal and plastic cement can realize gapless, without the cooperation offset.Further, although ultra-thin ultra-narrow moulding casing (such as, TV shell) in, metal covering and plastic rubber surface girth longer, metal covering and plastic rubber surface contact surface less, but casing structure of the present invention is owing to there being the existence of the first groove 22, be not easy to cause metal covering and plastic rubber surface to bond insecure, contact surface coordinates closely phenomenon, even if be subject under high temperature and load effect, contact surface is not yielding, cracking, still can keep good appearance characteristics.
