Rotating mechanism and folding terminal

Abstract

The invention discloses a rotating mechanism and a folding terminal. The rotating mechanism comprises a guide shaft, at least two rotating pieces and at least two constant-length units, and the rotating pieces are arranged on the two sides of the guide shaft. An arc-shaped groove is formed in the guide shaft; an arc-shaped part is arranged on the rotating piece and is arranged in the arc-shaped groove in a sliding manner. The constant-length unit is in a long-strip shape which has a fixed length and can be bent, the positioning end of the constant-length unit is fixedly or rotationally connected with the rotating piece located on one side of the guide shaft, and the sliding end of the constant-length unit is slidably connected to the rotating piece located on the other side of the guide shaft. The folding terminal is provided with the rotating mechanism. Through cooperation of the arc-shaped groove and the arc-shaped part, the two rotating pieces can rotate relative to the guide shaft,and then folding is achieved; when the rotating piece rotates around the guide shaft, the sliding end of the constant-length unit slides relative to the rotating piece, so that the total length of the folding terminal on the plane where the flexible screen is located is not changed, the flexible screen can bear the minimum external force in the folding process, the flexible screen is protected, and the service life is prolonged.

Description

technical field [0001] The invention relates to electronic equipment, in particular to a rotating mechanism and a folding terminal. Background technique [0002] The gradual maturity of flexible screen technology has led to great changes in terminal display methods, one of which is the emergence of foldable mobile phones, because the display screen can flexibly change and switch modes according to different usage scenarios. It is becoming a mainstream device The main direction of the manufacturer's next-generation mobile phone development. [0003] Since the flexible display screen is only a part of the foldable terminal device, to realize the foldable terminal device, the structure and other aspects need to be fully coordinated, so a hinge mechanism that can realize the folding of the terminal device is required. At the same time, in the bending area of ​​the equipment, since the bending radii of the various parts are different, their movement trajectories are also differe...

Problems solved by technology

[0006] An important defect of the sliding scheme in the prior art is that the mechanism needs the screen to provide a certain pulling force when sliding. If there is no screen or flexible parts similar to the screen to connect the two sides of the housing, the device cannot rotate when it is rotating. Realize the sliding function; another defect is that when the screen is unfolded, it is squeezed from the two sides of the device toward the middle, and sliding may also occur.
