Embodiment Construction

[0103] The following embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0104] Embodiments of the present application provide a folding device and an electronic device. The electronic device includes a folding device and a flexible display screen fixed to the folding device. The folding device can be unfolded to a flattened state, can also be folded to a closed state, and can also be in an intermediate state between the flattened state and the closed state. The flexible display unfolds and folds with the folding mechanism. The first support plate, the main shaft and the second support plate of the rotating mechanism of the folding device can jointly provide strong support for the flexible display screen in various forms, so that the flexible display screen is not easy to sag under the action of external force, which is beneficial to reduce the display screen. The risk of damage is impr...

Abstract

The application discloses a folding device and electronic equipment. The rotating mechanism of the folding device includes a main shaft, a first fixed frame, a first transmission arm, a first rotating arm, a first support plate, a second fixed frame, a second transmission arm, a second rotating arm and a second support plate. One end of the first transmission arm is slidably connected to the first fixed frame, and the other end is rotatably connected to the main shaft. The two ends of the first rotating arm are respectively rotatably connected to the first fixed frame and the main shaft. , and is fixedly connected to the first rotating arm. One end of the second transmission arm is slidably connected to the second fixed frame, the other end of the second transmission arm is rotatably connected to the main shaft, the two ends of the second rotatable arm are respectively rotatably connected to the second fixed frame and the main shaft, and the second support plate is set on the second fixed frame. between the frame and the main shaft, and fixedly connect the second rotating arm. The bending mechanism of the folding device can strongly support the flexible display screen, so that the reliability of the flexible display screen is high and the service life is long.

Description

technical field [0001] The present application relates to the technical field of foldable electronic products, in particular to a folding device and electronic equipment. Background technique [0002] In recent years, flexible display screens have been widely used in various foldable electronic devices due to their characteristics of being light, thin and not fragile. Foldable electronic equipment also includes a folding device for carrying a flexible display. The folding device generally includes two casings and a rotating mechanism connected between the two casings. The two casings are relatively folded or folded by the deformation of the rotating mechanism. Relatively unfolded, and drives the flexible display to fold or unfold. The current rotating mechanism usually adopts a multi-joint chain hinge structure. Although this structure can meet the bending requirements, it has a poor support effect on the flexible display screen. Hold electronic equipment), prone to dents,...
