Screen turning-over mechanism
A screen turning-over mechanism includes a rotating shaft connected to a screen and a motor drivably connected to the rotating shaft. The motor is connected to an electromagnetic damping loop which forms a closed path with the motor only when the motor is in a de-energized state. The rotating shaft is also connected to an elastic mechanism. When the motor is energized, the motor drives the rotating shaft to rotate to extend the screen, and the rotating shaft drives the elastic mechanism to deform elastically to store energy; and when the motor is de-energized, the elastic mechanism releases the stored energy to drive the rotating shaft to rotate to retract the screen. The screen turning-over mechanism according to the present application has a simple and compact structure, occupies a small volume of space, and has a long service life.
