Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do one to the accompanying drawing of required use in embodiment or the description of the Prior Art and introduce simply, apparently, accompanying drawing in the following describes is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the assembly drawing that the utility model portable mobile termianl is used casing embodiment.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 is the assembly drawing that the utility model portable mobile termianl is used casing embodiment.As shown in Figure 1, present embodiment portable mobile termianl casing comprises plastic shell 1, also comprises the metallic support 2 that adopts the zinc die casting alloys material to make, and metallic support 2 is fixed on the plastic shell 1.
Particularly, the metallic support 2 that the present embodiment portable mobile termianl adopts the zinc die casting alloys material to make with casing, machinery and processing characteristics that metallic support 2 is good, and because the zinc die casting alloys material has higher tensile strength, yield strength, impact toughness, hardness and percentage elongation preferably, thereby metallic support 2 can be made the planform of wall-forming thin structure complexity, and the surface of the metallic support 2 that employing zinc die casting alloys material is made is very smooth, than being easier to do various surface treatments, for example: electroplate, spraying, spray paint etc., and have good normal temperature mechanical performance and resistance to wear.In the course of processing of metallic support 2, do not inhale iron when the fusing of zinc die casting alloys material and die casting, do not corrode die mould, sticking to mould not, the molten metal temperature of zinc die casting alloys material can realize fully-automatic production during die casting about 420 degree, enhance productivity, and reduced the production cost of product.
Further, in order to effectively reduce the present embodiment portable mobile termianl with the weight of casing, can be provided with engraved structure 21 on the metallic support 2 in the present embodiment.Particularly, by at metallic support 2 engraved structure 21 being set, can effectively reduce the weight of metallic support 2.Preferably, plastic cement filling member 3 can be provided with in the engraved structure 21, the structural strength of metallic support 2 can be further strengthened by the plastic cement filling member.Can be provided with a plurality of engraved structures 21 on the metallic support 2 in the present embodiment.
