Description

A kind of mobile phone front casing

Technical field

The utility model relates to a kind of Mobile phone housing structure technical field, particularly a kind of mobile phone front casing.

Background technology

At present, the front casing of mobile phone generally adopts plastics to produce once by injection molding machine and forms, and such handset shell is thiner, and hardness is also lower, causes easily physical deformation, so useful life is shorter.In addition, when using such handset shell, often have the shortcoming of following several respects: first, when the assembling mobile phone, the direct fixed capacity of fore shell screen and LCD LCDs, these two parts have just become the framework of supporting mobile phone to a certain extent, are occurring that mobile phone falls or when clashing into, the pressure of fore shell will be discharged into touch-screen or LCD screen, causes screen slight crack or fragmentation to occur; The second, mainboard directly is fitted in the back of LCD screen, and heat is not easy in time to leave when mobile phone moves, and when especially running into the FPC of LCD and motherboard power supply and pressing close to very much, can feel obviously that mobile phone is hot; The 3rd, the HF link on the mainboard and antenna all can and LCD between cause interference.Therefore, how to provide the problems such as a kind of antijamming capability is strong, rapid heat dissipation, large, the on-deformable mobile phone front casing of intensity to become the in the industry focus of research.

The utility model content

The purpose of this utility model is for the defective of prior art and deficiency, and mobile phone front casing a kind of simple in structure, reasonable in design, easy to use is provided.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of mobile phone front casing described in the utility model, comprise housing, the inside casing of described housing closely is nested with metallic plate, described housing and described metallic plate are by the in-mould injection one-shot forming, the front surface of described metallic plate is provided with several reference columns, also is provided with FPC perforation and several louvres on the surface of metallic plate.

Further, described reference column is " L " shape, and the quantity of reference column is seven.

Further, the quantity of described louvre is three, and wherein two louvres are on the lower left corner and the lower right corner that is symmetricly set on metallic plate, and the another one louvre is arranged on the middle position at metallic plate top.

Further, described FPC perforation is arranged on the lower right side of metallic plate front surface.

After adopting said structure, the utility model beneficial effect is: a kind of mobile phone front casing described in the utility model, comprise housing, the inside casing of described housing closely is nested with metallic plate, described housing and described metallic plate are by the in-mould injection one-shot forming, the front surface of described metallic plate is provided with several reference columns, also is provided with FPC perforation and several louvres on the surface of metallic plate.When using the utility model, by the fixing parts such as mainboard, touch screen and LCD of metallic plate, can strengthen the intensity of housing, difficultly be damaged by external force, also have simultaneously good antijamming capability and heat dispersion, and then the useful life of extending cell phone.The utlity model has simple in structurely, arrange rationally, the advantage such as cost of manufacture is low.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

Shown in Fig. 1-2, a kind of mobile phone front casing described in the utility model comprises housing 1, and the inside casing of described housing 1 closely is nested with metallic plate 2, and described housing 1 and described metallic plate 2 are by the in-mould injection one-shot forming; Adopt the interior assembling of mould can avoid using independent press or mould to assemble, directly reduced the needs in manpower and space, place, reduce the production cost of producing links; Can improve simultaneously the structural strength of housing 1, strengthen radiating effect and the antijamming capability of mobile phone.

Shown in Fig. 1-4, for the ease of the assembling of the parts such as mainboard and screen, the front surface of described metallic plate 2 is provided with several reference columns 21, also is provided with FPC perforation 22 and several louvres 23 on the surface of metallic plate 2.Reference column 21 shapes of the present utility model are preferably " L " shape, the quantity of reference column 21 is preferably seven, the quantity of louvre 23 is preferably three, wherein two louvres 23 are on the lower left corner and the lower right corner that is symmetricly set on metallic plate 2, and another one louvre 23 is arranged on the middle position at metallic plate 2 tops; Described FPC perforation 22 is arranged on the lower right side of metallic plate 2 front surfaces.

The utility model shows that through after the various tests the anti-drop ability of this structural member is better than traditional front casing; Aspect heat-sinking capability, because metal partly has the good capacity of heat transmission, heat radiation is very fast during the mobile phone operation; Aspect antijamming capability, metal partly has good screening ability, and this structure can play the interference signal of Anti-Jamming and shielding LCD generation to a certain extent.In addition, this is simple in structure, reasonable in design, low cost of manufacture.

The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
