The invention relates to an anti-explosion armor for a light vehicle. The whole armor is of an interlayer structure, an inner plate is a metal plate which is attached to a protection area of the lightvehicle, and an outer plate is a carbon fiber plate or a carbon fiber composite material plate which is provided with outer convex arc surfaces; a plurality of metal cylinders are fixedly connected to the inner surface of the outer plate, and the number of the metal cylinders is identical to that of the outer convex arc surfaces; the inner plate and an oil separation plate form an oil storage layer, and the oil storage layer is filled with oil; a plurality of protruding surfaces are arranged on the oil separation plate, a safe valve is arranged on the top of each protruding surface, and the number of the protruding surfaces is identical to that of the metal cylinders; the cylinders of the metal cylinders are in a shape with two empty ends, the bottom edges of the protruding surfaces are circles, an opening at one end of each metal cylinder is fixedly connected with the bottom edge of the corresponding protruding surface, and an opening at the other end of each metal cylinder is fixedly connected with the bottom edge of the corresponding arc surface. The anti-explosion armor for the light vehicle is low in weight, multiple structure, material characteristics and inner detonation and explosion are used, the kinetic energy of impact and collision of external explosive substances is well consumed and counteracted, and damage and destroying of external explosion to the vehicle canbe effectively resisted.
