The invention discloses a train compartment noise reduction interior trim panel with a full-band noise reduction function, which comprises a first partition plate, a sound absorption plate and a second partition plate, a plurality of equidistantly arranged first sound insulation frames are arranged at the bottom of the first partition plate, a plurality of second sound insulation frames are arranged at the top of the second partition plate, and a first buffer pad and a support plate are sequentially arranged at the top of the first partition plate. The bottom of the second partition plate is provided with a second buffer pad and an inner decoration plate which are sequentially arranged. The first sound insulation frames are snapped with the second insulation frames. The sound absorption plate penetrates through the plurality of first sound insulation frames and the plurality of second insulation frames. The device is simple in structure and reasonable in design, the first sound insulation frames and the second sound insulation frames are connected through the sound absorption plate, so that connection and fixation are more stable, The sound insulation effect is greatly improved, the weight of the interior trim panel is reduced, the cost is reduced, environmental protection is facilitated, dislocation and falling are not prone to occurring when the interior trim panel is collided, meanwhile, the service life of the interior trim panel is prolonged, and damage of the interior trim panel is improved due to the fact that a cushion pad is used.
本发明公开了具有全频段降噪功能的列车车厢用降噪内饰板,包括第一隔板、吸音板以及第二隔板,第一隔板的底部设有若干个等距排列的第一隔音架,第二隔板的顶部设有若干个第二隔音架,第一隔板的顶部依次设有第一缓冲垫、支撑板,第二隔板的底部依次设有第二缓冲垫、内饰板,第一隔音架与第二隔音架相卡接,吸音板贯穿若干个第一隔音架和第二隔音架,本装置结构简单、设计合理,设置第一隔音架、第二隔音架通过吸音板相连,使得连接固定更加稳定,而且大大提高了隔音效果,减轻了内饰板自身的重量,降低了成本,有利于环境保护,在内饰板发生碰撞时,不容易发生错位和脱落,同时使用缓冲垫,增强了内饰板的使用寿命和损伤。
