Metal frame for device being equipped with wireless charging transmitter or receiver

Abstract

Disclosed herein is a metal frame for a device being equipped with a wireless charging transmitter or receiver including a plurality of perforation holes configured in at least one partial area of the metal frame, wherein the perforation hole has a diameter ranging from sub nm to several μm, and wherein an average distance between an arbitrary point A on a circumferential surface of a perforation hole, among the plurality of perforation holes, and an arbitrary point B on a circumferential surface of another perforation hole being adjacent to the perforation hole is equal to or less than a skin depth corresponding to a metallic material of the metal frame, and wherein point A and point B respectively correspond to points indicating a longest distance between the circumferential surfaces of each perforation hole to which point A and point B belong.Accordingly, the metal frame is expected to perform wireless charging by including at least a wireless charging receiver, i.e., enabling wireless charging to be carried out smoothly despite equipping a mobile device with a metal frame for its outer feature instead of a plastic frame, wherein the metal frame provides an excellent texture of premium quality and outstanding durability as compared to the plastic frame.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority from Korean Patent Application No. 10-2016-0033939 filed on Mar. 22, 2016, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]Field of the Invention[0003]The present invention relates to a metal frame for a device equipped with a wireless charging transmitter or receiver and, most particularly, to a metal frame for a device being equipped with a wireless charging transmitter or receiver including a plurality of perforation holes configured in at least one partial area of the metal frame, wherein the perforation hole has a diameter ranging from sub nm to several μm, and wherein an average distance between an arbitrary point A on a circumferential surface of a perforation hole, among the plurality of perforation holes, and an arbitrary point B on a circumferential surface of another perforation hole being ad...

AI Technical Summary

Benefits of technology

The present invention provides a metal frame for a device with wireless charging capabilities that is durable and has a premium quality texture. The metal frame can also have small perforation holes without compromising its durability.

Problems solved by technology

Therefore, it has become more difficult for the manufacturers to create their own distinguished functions that are related to the performance of the device.

Accordingly, the manufacturers are becoming more focused on the design of their mobile devices, and, therefore, the selection of the material for a frame configuring the outside feature of the mobile device has become one of the most important issues.

However, due to the characteristics of the plastic material, there were limitations in realizing high-quality texture in the mobile devices.

Evidently, metal frames may be disadvantageous in the aspect of weight as compared to the plastic frames.

However, due to the excellence in the design provided by the metal frame, the difference in weight between the two materials may not be significant.

Nevertheless, since metal acts as a shielding material that blocks out the frequency band for performing wireless charging, a problem of being incapable of performing wireless charging may occur.

Since a power line cannot pass through insulators (or non-conductors), such as plastic, heat may not be generated, or an extremely low level of heating may be performed.

Accordingly, there lies a disadvantage of not being able to apply a frame configured of a metallic material to a device that is equipped with a wireless charging transmitter or receiver.
