Folding screen bending mechanism and mobile terminal

Abstract

The invention relates to the technical field of folding screens, and discloses a folding screen bending mechanism and a mobile terminal. The folding screen bending mechanism comprises a supporting seat, a transmission assembly and a stretching assembly; the transmission assembly is arranged on the supporting seat and used for driving the first screen and the second screen to be folded or unfolded so as to enable the bendable part to be bent or unfolded, and the stretching assembly is used for stretching the first screen and the second screen after the bendable part is unfolded so as to flatten the bendable part under tensile force. The mobile terminal comprises the folding screen bending mechanism. The included angle between the first screen and the second screen can be adjusted according to user requirements, the bending radius of the bendable part is prevented from exceeding the limit bending radius limited by a screen material; therefore, the service life of the folding screen is prolonged, and the situation that the display effect of the folding screen and the user experience are affected due to damage caused by long-term excessive bending of the bendable part is avoided. The folding screen can be kept flat and attractive after being flattened in the long-term use process, and the phenomenon that the display effect of the folding screen is affected by bending creases is avoided.

Description

technical field [0001] The invention relates to the technical field of folding screens, in particular to a folding screen bending mechanism and a mobile terminal. Background technique [0002] The development and application of OLED flexible screen technology has become more and more mature, which has promoted the birth and development of foldable mobile phones. [0003] At present, the foldable solutions applied to mobile phones are mainly horizontal folding or vertical folding. The horizontal or vertical folding solutions usually adopt a folding hinge structure. Since the folding hinge structure involves multiple gears and pin shafts. The compound movement, the movement form is more complicated, As a result, the cumulative error is relatively large. When the mobile phone is folded, the actual bending radius of the screen is quite different from the preset bending radius, which may exceed the limit bending radius of the screen, resulting in a shorter service life of the scr...

Compound movement, the movement form is more complicated, As a result, the cumulative error is relatively large. When the mobile phone is folded, the actual bending radius of the screen is quite different from the preset bending radius, which may exceed the limit bending radius of the screen, resulting in a shorter service life of the screen, and during long-term use, After the screen is flattened, it is easy to leave creases, which is not beautiful enough
