Apple's new patent for foldable iPhone is approved: built-in spring layer can relieve folding pressure and external impulse

IT Home News on April 17th, according to a list recently announced by the United States Trademark and Patent Office (USPTO), Apple has obtained a patent for a foldable screen mobile phone, focusing on the introduction of a new spring layer concept to reduce Pressure during folding.

Apple said that the spring layer is composed of a metal spring array and is The spring layer is embedded withforce sensing structures (such as strain gauges)and other sensors. Additionally, the patent says that if desired, foam columns and other compressible structures can be interspersed with springs to help tailor the performance of the spring layers.

Spring layer material
The spring layer can be made of various flexible metals, such as: # #

spring steel

nickel chromium aluminum alloy
• copper alloy
• stainless steel
• # #Cobalt Nickel Alloyfenyefenye1.
Apple said that the introduction of a spring layer into folding screen devices can, on the one hand, relieve the external pressure on the device in events such as impact and extrusion, and on the other hand, it can also relieve the screen from repeated wear and tear. The stress during the folding and unfolding process is affected, thereby improving the durability of folding screen devices. Apple believes this spring layer can relieve external pressure and prevent excessive local deformation.

The above is the detailed content of Apple's new patent for foldable iPhone is approved: built-in spring layer can relieve folding pressure and external impulse. For more information, please follow other related articles on the PHP Chinese website!
