The utility model discloses a preceding shell subassembly comprises alloy die -casting frame and preceding shell integrated into one piece, and alloy panel frame passes through the screw fixation and in the front on the shell subassembly, forms the cell -phone center that has the metal outward appearance, and the processing volume of center member is little, and screwed connection's tautness is high, and the interior lateral wall of preceding shell is by alloy die -casting frame and alloy panel frame clamping, and the structural strength of cell -phone center is good.
Description
Technical field
The utility model relates to Mobile phone housing structure technical field, particularly relates to a kind of metal middle frame structure of mobile phone shell.
Background technology
Along with the raising of scientific and technological level, the profile of mobile phone towards more frivolous fashion development, mobile phone shell as the important composition parts of mobile phone, its aesthetic and requirement of strength more and more higher, metal-back, owing to being better than plastic housing in outward appearance and intensity, is therefore more and more applied in mobile phone.The metal-back occurred in the market generally refers to the center use metal structure in mobile phone shell, and the production technology of existing mobile phone metal center, mainly contains three kinds: 1, nanometer injection mo(u)lding after integral type CNC processing, and shortcoming is that processing capacity is large, cost is very high; 2, after aluminium punching press crude green body, CNC processes nanometer injection mo(u)lding again, and shortcoming is that intensity is general, cost is high; 3, directly do metal center after carrying out CNC processing with die casting aluminium, shortcoming is appearance poor, poor for applicability.
Utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of metal middle frame structure of mobile phone shell, this metal middle frame structure amount of machining is little, intensity is high and cost is low.
The technical solution adopted in the utility model is, design a kind of metal middle frame structure of mobile phone shell, comprise: fore shell, be fixed on the alloy die cast frame of fore shell inner ring, be fixed on the sheet alloy frame of fore shell outer ring, alloy die cast frame is fixedly connected with integral with fore shell, sheet alloy frame is provided with antenna breaking joint.Wherein, alloy die cast frame and fore shell injection moulding integrated molding, the two ends of sheet alloy frame are respectively equipped with four antenna breaking joints.
The madial wall of alloy die cast frame is provided with the first mounting panel, the madial wall of sheet alloy frame is provided with the second mounting panel, the bottom surface of the first mounting panel coordinates with the end face of the second mounting panel, and the first mounting panel is provided with screw hole, and the second mounting panel is provided with the through hole of this screw hole through.
Preferably, second mounting panel profile is L shape, one straight flange of the second mounting panel is fixedly connected with the madial wall of sheet alloy frame, form the slot of a side opening between another straight flange of second mounting panel and the madial wall of sheet alloy frame, the first mounting panel of alloy die cast frame is provided with the cutting that can coordinate and insert in this slot.
Compared with prior art, front shell assemblies of the present utility model is by alloy die cast frame and fore shell is one-body molded forms, sheet alloy frame is screwed in front shell assemblies, form the mobile phone center with metal appearance, the processing capacity of center component is little, the tautness that screw connects is high, and the outboard sidewalls of fore shell is by alloy die cast frame and the clamping of sheet alloy frame, and the structural strength of mobile phone center is good.
