Titanium and aluminum riveted metal intermediate frame and electronic equipment

Abstract

The invention relates to a titanium and aluminum riveted metal intermediate frame. The titanium and aluminum riveted metal intermediate frame comprises an intermediate plate and an edge frame, whereinthe edge frame is riveted on the intermediate plate, the intermediate plate is made of an aluminum alloy material, a convex edge is arranged at circumferential edge of the intermediate plate in a protruding way, the edge frame comprises a plurality of members, the plurality of members are sequentially connected in an end-to-end way, each member is made of a titanium alloy material, the hardness of the member is larger than the hardness of the intermediate plate, the members are all riveted at the circumferential edge of the intermediate plate, a clamping groove is formed in an inner side of each member and is connected with the convex edge, the intermediate plate is deformed by laminating an outer side surface of the edge frame so as to achieve riveting between the convex edge and the clamping grooves. Meanwhile, the invention also provides electronic equipment comprising the titanium and aluminum riveted metal intermediate frame. The titanium and aluminum riveted metal intermediate frame has the beneficial effects that the intermediate plate made of titanium alloy and the edge frame made of titanium alloy are riveted by lamination and deformation, the production efficiency is improved, and the manufacturing cost is favorably reduced.

Description

technical field [0001] The invention relates to the technical field of middle frame manufacturing, in particular to an aluminum-aluminum riveted metal middle frame and an electronic device using the aluminum-aluminum riveted metal middle frame. Background technique [0002] With the continuous development of mobile terminal technology, the application of smart phones, handheld computers, smart watches and other electronic devices has become very common and has become an important part of people's work and life. The shell of electronic devices usually adopts a metal middle frame structure. The frame structure has the advantages of wear resistance and easy heat dissipation, and at the same time can make the product leave a high-end impression on the user. [0003] The metal middle frame structure mainly includes: a metal frame and a middle plate, while the traditional metal middle frame structure generally forms the prototype of the metal middle frame integrally by forging and...

AI Technical Summary

Problems solved by technology

[0003] The metal middle frame structure mainly includes: a metal frame and a middle plate, while the traditional metal middle frame structure generally forms the prototype of the metal middle frame integrally by forging and pressing stainless steel blanks, and then performs CNC finishing on the prototype of the metal middle frame , on the one hand, this method of forming and then finishing through blanks requires more waste to be cut off, resulting in more waste of materials

On the other hand, the hardness of the stainless steel blank is relatively high, and the loss of the tool during finishing is large, and the speed is relatively slow.

The above problems lead to the low production efficiency of the traditional metal middle frame production, and it is difficult to reduce the manufacturing cost
