Description

Portable electron device

[technical field]

The utility model relates to a kind of portable electron device, refers to that especially a kind of usefulness one integral type metal shell shields the integrated circuit module and increases portable electron device attractive in appearance.

[background technology]

Along with developing rapidly of Information technology, portable electron device such as mobile phone, PDA popularity rates such as (personal digital assistants) raise day by day, and the aesthetic measure of these electronic installations and haptic effect also more and more are subjected to people's attention and attention.Because plurality of advantages such as plastic material itself has light weight, cost is low, process technology is simple, anticorrosive are so most of portable electron device all adopts plastic casing.Yet the forward and backward lid of conventional plastic product the offset problem occurs easily when cooperating the formation shell.And along with the continuous development of consumption electronic products, the continuous variation of consumer demand except that making improvements on the product function, also needs attractive at aspects such as product-forming, selection, texture.Therefore, some metal shells are used to portable electron device, not only make product appearance beautiful, and also have the shielding electromagnetic wave effect to a certain extent.

But the mode that traditional portable electron device all adopts forward and backward shell to make up is come the integrated circuit module in the screening electron device.United States Patent (USP) the 6th, 229, disclosed for No. 993 a kind of by forward and backward mobile phone outer casing dimerous, the mainly mode combination that will coincide mutually by forward and backward two parts shell, wherein in preceding shell side wall, be provided with the ligule shell fragment, be housed in the groove of bonnet by the ligule shell fragment and the effect of screw with forward and backward two parts strong bonded.Yet, adopt riveted or welding procedure all can cause certain defective to metalwork to product appearance, fact proved that will remove these defectives can increase manufacturing cost and can cause difficulty to production in enormous quantities.

[author content]

The utility model main purpose be to provide a kind of surface aesthetic, effectively shielding electromagnetic wave and make easily, lower-cost portable electron device.

For achieving the above object, the utility model by the following technical solutions: this portable electron device comprises and utilizes integral type metal shell that metal extrusion forming technology (impact extrusion) forms and the bottom that is housed in the integrated circuit modules in this metal shell and cooperates with described metal shell bottom.Wherein, on the main panel of this metal shell, be provided with, then be provided with passage, insert for integrated circuit modules in its bottom for the rectangular opening that display screen is installed and some keyholes for the installation button.And bottom is used for sealing above-mentioned metal shell.In addition, this portable electron device also is provided with the plastic stent that is used for supporting the located integrated circuit module, and this plastic stent is provided with slide rail and establishes electronic building bricks such as circuit board with group.

Compared to prior art, the utility model portable electron device increases aesthetic measure because shell can effectively reduce the position that needs connection by the monolithic construction design, reduces cost, and further prevents Electromagnetic Interference effectively.

[embodiment]

Shown in Figure 1 is that the utility model is applied to the embodiment on the mobile phone, comprises an integral type metal shell 5, metal bottom cover 4, button 6, display screen 7, integrated circuit module 8 and plastic stent 9 (as shown in Figure 4).Wherein metal shell 5 its main panels 51 are provided with the some keyholes 512 for rectangular opening 511 that display screen 7 is installed and installation button 6, button 6 is used for input instruction, display screen 7 is used for display message, integrated circuit module 8 is used for receiving and processing signals, and bottom 4 then is arranged on the bottom passage 57 of metal shell 5 and sentences closed metal shell 5.

Figure 2 shows that the manufacture method of metal shell embodiment illustrated in fig. 15, at first, utilize ductile metal, make cuboid blank piece 3 as aluminium, aluminium alloy or copper etc., then insert in the die cavity 22 of mould 2, wherein the shape of die cavity 22 and blank piece 3 match.Then, starting drift 1 moves downward, the cross-sectional area of this drift 1 is more smaller than the cross-sectional area of cuboid blank piece 3, therefore when drift 1 just has been pressed on cuboid blank piece 3 surperficial, can guarantee that the edge of its edge and cuboid blank piece 3 on average leaves the distance of 1～3mm, and when drift 1 continued to move downward extruding cuboid blank piece 3, plastic deformation took place and moves in the other direction in die cavity around drift 1 in metal blank piece 3, thereby formed the cuboid die cavity of hollow.At last, upwards return drift 1, take out gained hollow metal shell 5 blanks.

Please refer to shown in Figure 3ly, the metal shell 5 after above-mentioned forming processes comprises main panel 51, base plate 54 and three sidewalls 53, and forms passages 57 in its bottom 52.After this by to the local stamping technology that adopts of aforementioned metal shell 5 blanks, on main panel 51, offer rectangular opening 511 than the distal part position,, below rectangular opening 511, go out some keyholes 512 for button 6 is installed for display screen 7 is installed apart from passage 57.In addition at the some through holes 531,532 of sidewall 53 punching presses, for other function key is installed.And the bottom of metal shell 5 52 inner surfaces offer shrinkage pool 541 and with the isometric groove 56 in bottom surface, adopt different decoration technologys that above-mentioned metal shell 5 is carried out surface treatment according to product needed more at last, just can obtain the beautiful mobile phone outer casing of outward appearance.

Please refer to shown in Figure 4ly, assembling is during mobile phone, in the metal shell 5 of can earlier display screen 7 being packed into, the location also is bonded on the frame of rectangular opening 511, then, metal shell main panel 51 is placed down, flexible keypad 6 is installed is made it corresponding to each keyhole 512 and protrude in the surface of main panel 51.Then, integrated circuit module 8 is placed on the plastic stent 9, this plastic stent 9 is made up of diapire (not label) and two opposite side walls (not label), and described two opposite side walls is provided with a pair of slide rail 91, power circuit board 81 along its slip into and positioning and fixing on plastic stent 9.Then, with the aforementioned plastic stent 9 that is assembled with integrated circuit modules 8 to insert in the hollow metal shells 5 from passage 57, and make the above shrinkage pool 541 snappings of the set snapping piece of its lower surface and metal shell 5, with firm affixed plastic stent in described metal shell 5.

Please refer to shown in Figure 5ly, last, the bottom 4 that will be provided with projection shell fragment (figure does not show) at the edge inserts in the groove 56 of metal shells 5 bottoms, utilizes projection shell fragment (figure does not show) and groove 56 to fasten, and with closed channel 57, thereby forms the integral type mobile phone.Because outward appearance does not have seam, not only attractive in appearance but also electromagnetic wave shielding effect preferably in addition.

Obviously, this integral type housing designs also can be applicable to reach both artistic and practical effect as hand-held devices such as PDA.
