Abstract

The invention discloses a method for preparing a middle frame, the middle frame and electronic equipment. The method comprises the following steps: a metal master plate is formed based on a metal substrate through extrusion molding; the metal master plate is pretreated to form multiple frame precast slabs; grooves are formed in the inner side walls of the frame precast slabs; a middle plate is provided; multiple convex parts are arranged on the side wall of the middle plate at intervals; and the convex parts are assembled in the grooves to arrange the multiple frame precast slabs on the peripheral sides of the middle plate to form an annular outer frame surrounding the middle plate so as to obtain the middle frame. The method is high in utilization rate of raw materials and low in total wastes to reduce the material cost, and meanwhile, has the advantages of simple procedures, stable sizes, low machining cost, simple fixing process and high production efficiency; and the middle frame prepared by the method is excellent in appearance quality and high in overall strength, and further improves the product market competitivity.

Description

technical field [0001] The present invention relates to the field of electronic equipment, in particular, to a method for preparing a middle frame, a middle frame and electronic equipment. Background technique [0002] At present, technology in the field of electronic equipment is developing rapidly, and manufacturers in the mobile terminal industry chain are also following the industry trend and constantly upgrading and changing their product technology. Among them, the metal middle frame can improve the overall strength of the product and be used directly as a side frame due to its anti-fall, good wear resistance, excellent corrosion resistance, metallic texture, delicate hand feeling, and good user experience, and has become a mainstream mobile phone. Standard configuration of terminal models. [0003] However, the current middle frame still has problems such as complicated processing procedures and high processing costs. Contents of the invention [0004] The present...
