Problems solved by technology

At the same time, due to the increasing demand for portability of electronic products, taking into account the two needs of protection and portability, the selection of frame materials faces higher challenges.
[0003] The existing routinely used materials are aluminum alloy or stainless steel. Aluminum alloy has great advantages in terms of specific gravity, but in terms of strength, it is often difficult to meet the strong protection of internal hardware.
The strength of stainless steel is enough to support the current product demand, but due to the high specific gravity, it will often increase the weight of the whole machine and reduce the portability. It is also out of compromise that stainless steel is used to make the middle frame, and other lighter materials such as plastic are used. material to cover other relatively unimportant parts, but this method will make it difficult for electronic hardware to be fully protected

Abstract

The invention discloses an amorphous alloy shell, which comprises a shell body with at least one wall. The amorphous alloy shellis characterized in that at least one part of the shell body is preparedfrom an amorphous alloy material, wherein the hardness of the amorphous alloy material is notless than 350Hv, and the relative permeability of the amorphous alloy material is less than 1.02. The amorphous alloy shell provided by the invention has the characteristics of high strength and low relative permeability, cannot be in coupled reaction with electron components, and cannot affect signal transmission.

Description

technical field [0001] The invention relates to a shell, in particular to an amorphous alloy shell. Background technique [0002] At present, electronic devices such as mobile phones, tablet computers, VR glasses, and drones can be functionally divided into two parts: the electronic part is used to provide the functional utility of the electronic device; the outer frame part is used to provide physical protection for the electronic part. Protect. At the same time, due to the increasing demand for portability of electronic products, taking into account the two needs of protection and portability, the selection of frame materials faces higher challenges. [0003] The conventionally used materials are aluminum alloy or stainless steel. Aluminum alloy has great advantages in terms of specific gravity, but in terms of strength, it is often difficult to meet the strong protection of internal hardware. The strength of stainless steel is enough to support the current product deman...
