Description

Rotating mechanism and foldable display terminal Technical Field The embodiment of the application relates to the field of electronic products, in particular to a rotating mechanism and a foldable display terminal. Background Along with commercialization of flexible display screens, foldable flexible screen mobile phones, foldable flexible screen tablet computers, wearable electronic devices with foldable flexible screens and the like are an important evolution direction of future intelligent terminal devices. The foldable display terminal can obtain a larger display area under the unfolding state, and the film watching effect is improved. The folding display terminal can obtain smaller volume under the folding state, and is convenient for users to carry. The foldable display terminal at least comprises a flexible screen, two structural members for bearing the flexible screen and a rotating mechanism. The two structural members are connected to two sides of the rotating mechanism. In the actual use process, the rotating mechanism drives the two structural members to rotate, so that the foldable display terminal is in a folded state, a hovering state or a flat state.
