Apple's new patent exposed: Folding screen mobile phone introduces spring layer technology to improve durability

In recent news, Apple has obtained a patent for a foldable screen mobile phone, which was published by the United States Trademark and Patent Office (USPTO). This patent mainly introduces a new spring layer concept to reduce the pressure when folding and improve the durability of folding screen mobile phones.

According to the patent description, this innovative spring layer is finely composed of an array of metal springs, in which force sensors such as strain gauges and other sensing structures are cleverly embedded. Apple has even proposed that when needed, compressible structures such as foam columns can be combined with springs to fine-tune the performance of the spring layer to achieve more optimized results.

#The spring layer can be used in various flexible Metals, such as spring steel, nickel-chromium alloy, aluminum alloy, copper alloy, etc., these metals have good elasticity and durability. As far as the editor understands, this spring layer design has dual advantages. On the one hand, it can effectively relieve external pressure and avoid excessive deformation of the device when the device is hit or squeezed; on the other hand, when the screen is repeatedly folded and unfolded, it can also effectively relieve the impact of stress, greatly improving the performance of the folding screen. Phone durability.

The acquisition of this patent will undoubtedly lay a solid foundation for Apple’s further development in the field of folding screen mobile phones, and may lead a new round of innovation in folding screen mobile phone technology.
