The invention relates to the technical field of
electronic equipment, and particularly relates to a
metal bottom casing mobile terminal. The
metal bottom casing mobile terminal comprises a
metal bottom casing, a middle frame and a display screen
assembly, wherein the middle frame is clamped at the upper part of the metal bottom casing; the display screen
assembly is mounted in the middle frame; the metal bottom casing comprises a metal base and a plastic body filled in the metal base. Compared with the metal case made by profile aluminum block CNC (computer
numerical control) in the prior art, the metal bottom casing structure formed by metal plate
stamping and nano injection molding has the advantages that on the basis of keeping all the properties required by the mobile terminal, the production cost is greatly reduced, and the production efficiency is improved; moreover, due to the adoption of a metal frame and a structure of an injection molding piece embedded into the inner side of the metal frame, the intensity of the whole equipment is improved, and the production cost is reduced; moreover, the hard contact between the metal frame and a display screen
assembly is buffered, so that the mobile terminal is higher in security, stability and reliability.
