Problems solved by technology

In other words, the common rotating shaft is a static rotating shaft, while the folding screen mobile phone considers dynamic rotation, and the fault stress phenomenon will appear during the rotation of the screen. For example, when a book is closed and unfolded, the page edge cannot be kept flush. Similarly, During the bending process of the screen, each layer of the screen receives shear stress in different directions. Assuming that the middle frame attached to the screen remains unchanged, it will move in the opposite direction of the sliding direction of the layer at the top of the screen. Pulling up, this will inevitably increase the internal stress of the screen, which will lead to the delamination of the screen

Abstract

The invention discloses a rotating shaft mechanism and an electronic device. The rotating shaft mechanism is applied to the foldable electronic device. According to the embodiment of the invention, the first screen part and the second screen part of the electronic device do opposite motion through the rotating shaft mechanism, so that the screen is in an unfolded state. The rotating shaft mechanism retracts inwards relative to the shell of the electronic device so as to reduce the external stress of the shell on the screen when the screen is unfolded, so that the screen is protected from beingdamaged, the reliability of the electronic device is enhanced, and the service life is prolonged.

Description

technical field [0001] The present application relates to the technical field of mobile communication, in particular to the technical field of mobile equipment, and in particular to a shaft mechanism and an electronic device. Background technique [0002] With the development of communication technology, electronic devices such as smart phones are becoming more and more popular. With the popularization of the concept of full screen, the current smart phone market is becoming more and more homogeneous following the rhythm of internationally renowned terminal manufacturers. In a wave of pursuit of full screen, special-shaped screens (notch screens), water drop screens, etc. have become major The focus of competition for terminal manufacturers, mobile phone products are more stereotyped. With the successful development of flexible screens, it has been successfully applied to actual production and life. New concept mobile phones are also born accordingly. With the launch of Sa...
