Abstract

The invention belongs to the technical field of automobile parts, and particularly provides a sound-proof EVA board for an automobile. The sound-proof EVA board comprises a board body and resonance noise reduction mechanisms; an adornment layer is fixedly arranged on the inner surface of the board body, and an installation groove is formed in the board body; the installation groove is internally provided with the resonance noise reduction mechanisms; the resonance noise reduction mechanisms comprise sound transmitting holes, sound-absorbing cavities and sound wave pieces; the sound transmitting holes are evenly formed in the left end wall of the board body; the sound-absorbing cavities are positioned at the right ends of the sound transmitting holes; the sound-absorbing cavities are arranged in the installation groove, the left ends of the sound-absorbing cavities are fixedly mounted on the internal wall of the left end of the board body, the openings of the sound-absorbing cavities are opposite to the sound transmitting holes, the sound-absorbing cavities are of oval tube types, the inner surfaces of the right ends of the sound-absorbing cavities are in arc shapes, the internal walls of the upper and lower ends of the sound-absorbing cavities are symmetrically provided with the sound wave pieces, and the outer sides of the sound-absorbing cavities are provided with sound-proofcotton; and the sound-proof EVA board is mainly used for solving the problems that an EVA board in the prior art cannot be popularized and used in motor homes, the sound insulation effect is poor, and privacy life of people is prone to being leaked.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a sound-insulating EVA plate for automobiles. Background technique [0002] At present, the existing thermal insulation materials include various foam materials, such as polyethylene foam (EVA) thermal insulation materials, because EVA has certain water and heat insulation and shockproof performance, and is non-toxic, environmentally friendly and beautiful, it is often used as a Thermal insulation material. However, the existing EVA insulation materials cannot meet people's requirements for materials, especially the existing EVA insulation boards have little effect on sound insulation, do not meet the requirements of automobiles and related industries, and are not conducive to the survival and development of enterprises. RVs are no longer out of reach, and even many people use RVs as their residences. However, due to the poor sound insulation effect of the existin...
