Heat preservation plate structure for light vehicle

The utility model discloses a heat preservation plate structure for a light vehicle, and relates to the technical field of heat preservation plates. The heat preservation plate structure for the light vehicle comprises an anti-crack layer, a heat preservation layer is arranged at the bottom of the anti-crack layer, a sound insulation layer is arranged at the bottom of the heat preservation layer, a noise reduction layer is arranged at the bottom of the sound insulation layer, a reinforcing layer is arranged at the bottom of the noise reduction layer, and a flame-retardant wear-resistant layer is arranged at the bottom of the reinforcing layer. The reflection frequency of external sound waves transmitted to the sound absorption plate can be increased through the conical grooves in the sound absorption plate, then sound wave energy absorbed by the sound absorption plate is increased, the effect of reducing the external sound waves is achieved, meanwhile, the cavity is formed in the cement mortar layer, the nois
