Crumple structure of vehicle-mounted screen

The invention relates to the technical field of vehicle-mounted screens, in particular to a crumple structure of a vehicle-mounted screen. The crumple structure comprises a first connecting shaft, a second connecting shaft and a limiting block with the fixed position. The second connecting shaft is connected with the vehicle-mounted screen and can make autorotation movement in the axial directionof the second connecting shaft. A protrusion with the length being smaller than that of the second connecting shaft is formed on the outer wall of the second connecting shaft. One end of the first connecting shaft is fixed to the side wall of the second connecting shaft, and the other end of the first connecting shaft is vertically connected with the limiting block and slides on the surface of thelimiting block. The crumple structure aims to solve the technical problems that as for a traditional crumple structure of the vehicle-mounted screen, due to limit of the crumple structure, the crumple distance is uncontrollab
