Description

Curtain elevating gear and on-vehicle projection equipment Technical Field The utility model relates to the technical field of projection screens, in particular to a curtain lifting device and vehicle-mounted projection equipment. Background With the development of automobile technology, in order to meet the high-quality driving experience of vehicle users, vehicle manufacturers integrate more and more advanced vehicle-mounted entertainment systems into vehicles, so that projection systems are beginning to be applied to the vehicle-mounted entertainment systems of the vehicles, and by installing projectors in the rear seat area of the vehicles, images are projected to special curtains capable of lifting in front of the vehicles, so that various entertainment contents such as more abundant movies, animations, games and the like are realized. At present, traditional electronic flexible curtain fixed mounting is in the top region of vehicle, including the upper and lower supporting mechanism and the intermediate supporting mechanism of curtain, when the curtain put down, supporting mechanism only realizes the support of curtain, can't stop the curtain in a user preset's position, therefore can't realize the accurate control to curtain demand position, simultaneously, supporting mechanism embeds the elastic connection spare in order to realize the anti-vibration effect of curtain in the upper and lower left and right directions under the user state generally, but the vehicle is on the way of the driving, especially when through the pothole road surface or have great tunnel, very easily cause strong impact to the curtain, supporting mechanism with elastic connection spare still can't restrain the strong shake that the curtain consequently produced.
