Folding rotating shaft assembly based on belt linkage and mobile terminal thereof

Abstract

The invention relates to the field of flexible screens, and discloses a folding rotating shaft assembly based on belt linkage and a mobile terminal thereof. The folding rotating shaft assembly comprises a central shell and two movable shells. The two movable shells are arranged on the two sides of the central shell and can rotate freely through rotating shafts. Synchronous movement mechanisms forthe two movable shells to synchronously open and close are arranged in the central shell. The two ends of the movable shells are provided with screen avoiding mechanisms for protecting flexible screens. Each movable shell comprises a middle connecting plate, an arc-shaped groove, an upper cover plate and a main shell. In the folding rotating shaft assembly, an elliptical connecting plate drives fixed plates to move away from the screens, at the moment, the two fixed plates can form a rectangular space at the position of the middle connecting plate, the synchronous mechanisms are placed in therectangular space on the two sides, through belt connection, when the large cambered surface appearance is formed at the two ends of the middle shell, the inner space of the middle shell is not largeenough to arrange the movement mechanisms, rectangular mechanisms on the two side can be arranged below screen avoiding plates, the structural space is effectively utilized, and spaces are given to batteries.

Description

Technical field [0001] The invention relates to the field of flexible screens, in particular to a folding hinge assembly based on belt linkage and a mobile terminal thereof. Background technique [0002] Flexible screen refers to flexible OLED. The successful mass production of flexible screens is not only a major benefit to the manufacturing of a new generation of high-end smartphones, but also has a profound impact on the application of wearable devices due to its low power consumption and flexibility. [0003] The current flexible screen cannot be opened and closed at the same time on both sides of the screen during use. As a result, two hands are required to open and merge the two sides of the phone at the same time, and the screen is in the middle of the screen when the screen is closed. Part of the arc-shaped folds will appear, and the current flexible screen does not have an avoiding mechanism when the screen is closed, which causes the screen to easily appear gaps after th...

AI Technical Summary

Problems solved by technology

[0003] The current flexible screen cannot realize the function of opening and closing the screens on both sides at the same time during use, resulting in the need for two hands to open and merge the two sides of the phone at the same time, and the middle of the screen when the screen is closed There will be arc-shaped folds in some parts, and the current flexible screen does not have an avoidance mechanism when the screen is closed, resulting in gaps on the screen after the screen is closed, which affects the aesthetics
