The invention discloses a screen overturning mechanism, which comprises a screen base and a screen, wherein the screen is rotatably connected to the screen base; a driving device used for unfolding and folding the screen is arranged on the screen base; the driving device comprises a rotating piece, a power mechanism, a connecting rod mechanism and a reset piece, wherein the rotating piece is rotatably arranged on one side of the screen base; the power mechanism connected to the rotating piece and is used for driving the rotating piece to rotate; a driving end of the connecting rod mechanism isconnected to the circumferential surface of the rotating piece, a driven end of the connecting rod mechanism is connected to the middle position of one side, close to the rotating piece, of the screen, and the connecting rod mechanism is used for directly driving the screen to unfold and fold; and the reset piece is fixedly connected to one end, far away from the power mechanism, of the rotatingpiece and is used for folding and resetting the screen through the elastic force of the reset piece and sucking the screen on the screen base. According to the screen overturning mechanism, the screenwidth can be maximized in the limited space, the screen stress is more balanced, the screen overturning mechanism is not prone to generate the phenomena such as a warping corner and the like, and thescreen can be designed to be very thin.

    一种屏幕翻转机构,包括屏幕底座和与屏幕底座转动连接的屏幕,屏幕底座上安装有用于展开和收起屏幕的驱动装置,所述驱动装置包括:转动件,可转动的安装在屏幕底座的一侧;动力机构,与所述转动件连接,用于驱动所述转动件转动;连杆机构,其驱动端与所述转动件的圆周面连接,所述连杆机构的被动端与屏幕靠近所述转动件的一侧的中间位置连接,用于直接带动屏幕展开和收起;复位件,与所述转动件远离所述动力机构的一端固定连接,用于通过其自身的弹力将屏幕收起复位,并将屏幕吸合在屏幕底座上。本发明的屏幕翻转机构能在有限空间下将屏幕宽度做到最大,屏幕受力更加均衡,不容易产生翘角等现象,屏幕可以设计的非常薄。
