Embodiment Construction

[0037] 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.

[0038] 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, a metal middle frame processing process and an electronic device provided with the metal middle frame. The metal middle frame comprises a middle plate, a border arranged around the middle plate and connected with the edge of the middle plate through butt welding, and a plastic piece in the gap between the middle plate and the border through injection molding. The metal middle frame processing process comprises the following steps: the border is processed and formed through an extrusion process and a CNC process; a die casting process is adopted to form the middle plate; the middle plate is connected in the border through butt welding; the melted plastic is injected to the gap between the middle plate and the border; and after cooling, the formed metal middle frame is subjected to surface processing. Thus, stable and reliable connection between the middle plate and the border can be realized, the processing amount of the CNC process can be saved, the whole metal middle frame processing time is reduced, and the metal middle frame manufacturing cost is further reduced and besides, the metal middle frame surface processing quality is improved.

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...
