The invention discloses an early-warning double-layer protective plate. The early-warning double-layer protective plate comprises a first fixed plate and a second fixed plate arranged above one side of the first fixed plate, a first protecting plate and a second protecting plate are connected between the first fixed plate and the second fixed plate, the second protecting plate is located below the first protecting plate and is a steel wire mesh of an arc structure convex outwards, and the top of the second protecting plate is welded to the bottom of the first protecting plate. By means of the mode, the early-warning double-layer protective plate is installed below a vehicle engine, the second protecting plate is the steel wire mesh, is firm in structure and has certain elasticity and tenacity, in collision, a barrier first makes contact with the second protecting plate, the second protecting plate pushes the barrier down or sounds through friction to alert a driver to reduce speed, impact on the first fixing plate is effectively reduced, the protection effect is good, deformation of the first fixed plate is relieved, and later-stage maintenance cost is reduced.
