Example Embodiment

[0038] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented 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.

[0039] 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 a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. The terms "inner", "outer", "left", "right" and similar expressions used herein are for illustrative purposes on...

Abstract

The invention relates to a metal middle frame processing technique, a metal middle frame and an electronic device with the metal middle frame. The metal middle frame comprises a middle plate, a frame and a rubber piece. The frame is arranged around the middle plate and is connected to the edge of the middle plate through overlapping welding. The rubber piece is moulded in a slit between the middle plate and the frame 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; using the die-casting technique to mould the middle plate; connecting the middle plate into the frame through the overlapping welding; 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, stable and reliable connection between the middle plate and the frame is achieved; processing quantity of the CNC technique is reduced; processing time in the whole metal middle frame is reduced; manufacturing cost of the metal middle frame is reduced; and meanwhile, improving of surface processing quality of the metal middle frame is facilitated.

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 containing 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 plate and a frame. Generally, the middle frame has a variety of molding methods. [0003] For example, the middle frame is formed by pressing or punching to form a middle frame rough blank, and then the middle frame rough blank is processed into a middle frame product through a CNC process, but the amount of CNC machining is too large, resulting in too long processing time and high cost. [0004] For another example, the rough blank of the middle frame is first processed by die casting process, and then the part of the rough blank of the middle frame is proce...
