The invention discloses an integrated shock-resistant automobile sound insulation dash panel with a built-in hidden water chute. The dash panel comprises a front panel, a sinking groove is formed in the front plate, and a back plate, an air bag layer and an interlayer are arranged in the sinking groove; the interlayer comprises a water guide pipeline, second arc-shaped spacers are arranged outside the water guide pipeline, and a first arc-shaped spacer is arranged between the second arc-shaped spacers; an air chamber spacer is arranged in the first arc-shaped spacer, and an air bag is arranged in the air chamber; a water inlet is formed in the top surface of the front plate, a sleeve is arranged in the water inlet, and a filter screen is arranged on the sleeve; an annular air bag is arranged on the water guide pipeline and communicated with the air chamber, and a spring is arranged on the water guide pipeline. The cavity in the interlayer can weaken noise, the water guide pipeline can discharge accumulated water above the front wall plate, when the front wall plate is impacted, the back plate can sink downwards, air in the air bag layer enters the air bag to improve the impact resistance of the interlayer, and meanwhile the annular air bag can expand to protect the water guide pipeline.

    本发明公开了一种内置隐藏式导水槽的一体化抗冲击汽车隔音前围板,前围板包括前板;前板设有沉槽,沉槽内设有背板、气囊层以及夹层;夹层包括导水管道,导水管道外设有第二弧形隔片,第二弧形隔片之间设有第一弧形隔片;第一弧形隔片内设有气室隔片,气室内设有气囊;前板顶面设有进水口,进水口内有套管,套管上有滤网;导水管道上设有环形气囊,环形气囊与气室连通,导水管道上设有弹簧。本发明夹层内的空腔可减弱噪音,导水管道可排出前围板上方的积水,且在前围板受冲击时,背板会向下凹陷,使气囊层内的气体进入气囊,以提高夹层的抗冲击能力,同时环形气囊会膨胀以保护导水管道。
