[0002] With the development of society and the improvement of people's quality of life, automobiles have become an indispensable means of transportation for people to travel. In order to better meet users' needs, electronic flip screens for entertainment, study and work are often installed in automobiles. To save interior space and protect the screen, the screen usually adopts a hidden design, and the hiding effect is achieved by arranging a flip structure or a folding structure on the screen, so that the screen can be unfolded as required. However, with this design, when the vehicle is driving, road bumping, sudden braking and other conditions will cause the screen to shake. Such shaking may not only cause the screen to unfold accidentally, obstruct the driver's vision or distract the driver, increasing driving risks, but also may cause the screen to collide with other components, resulting in scratches on the screen surface in minor cases, and loose or damaged internal circuits of the screen in severe cases, which affects the normal display of the screen and even leads to the scrapping of the screen.
