Embodiment Construction

[0043] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0044] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and similar expressions are used herein for the purpose of descripti...

Abstract

The invention relates to a metal middle frame processing technique, a metal middle frame and an electronic device. The metal middle frame comprises a frame, a middle plate and a rubber piece. A groove or a protrusion which extends circumferentially is arranged on the inner surface of the frame. A protrusion or a groove which is in interference fit with the groove or the protrusion is arranged in the edge of the middle plate. The rubber piece is moulded between the frame and the middle plate in an injection manner. The metal middle frame processing technique comprises following steps of through squeezing technique and CNC technique, processing and moulding the frame with the groove or the protrusion; using the die-casting technique to process and mould the middle plate with the protrusion or the groove; heating the groove or cooling the protrusion, matching the protrusion or the groove and recovering the temperature of the protrusion or the groove to the initial temperature; injecting fused rubber in a slit between the middle plate and the frame; and carrying out cooling and surface processing on the moulded metal middle frame. In this way, processing quantity of the CNC technique is reduced; processing time in the whole metal middle frame is reduced; and manufacturing cost of the metal middle frame is reduced.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a metal middle frame, a metal middle frame processing technology and an electronic device including the metal middle frame. Background technique [0002] In electronic devices such as smart phones and handheld computers, a middle frame structure is usually adopted. The middle frame of this structure includes a middle board and a frame. Generally, there are various molding methods for the middle frame. [0003] For example, the middle frame is formed by pier pressing or stamping to form a middle frame rough blank, and then the middle frame rough blank is processed into a middle frame product by CNC technology, but the CNC processing volume is too large, resulting in long processing time and high cost. [0004] As another example, the rough blank of the middle frame is processed and formed by the die-casting process first, and then part of the rough blank of the mid...
