The elevator double-layer sound insulation structure comprises a first sound insulation structure, a second sound insulation structure and an anti-disengaging limiting structure, and the second sound insulation structure comprises a car top plate and a car wall plate; the anti-falling limiting structure is used for preventing the first sound insulation structure from falling off from the second sound insulation structure; the first sound insulation structure comprises supporting frames fixedly arranged on the second sound insulation structure, and the supporting frames form a rectangular lattice-shaped array. The elastic film covers the supporting frame; the closed cavity is defined by the supporting frame, the elastic film and the second sound insulation structure; and the resonance sound absorber is arranged on the elastic film. The sound insulation performance of the lift car can be effectively improved, and external noise entering the lift car through the lift car is reduced.
本发明公开了一种电梯双层隔音结构,包括第一隔音结构、第二隔音结构和防脱限位结构,其中第二隔音结构包括轿顶板和轿壁板;所述防脱限位结构用于防止第一隔音结构从第二隔音结构上脱落;所述第一隔音结构包括:支撑框架,固定设置在所述第二隔音结构上,所述支撑框架构成矩形的晶格状阵列;弹性薄膜,覆盖在所述支撑框架上;密闭空腔,由所述支撑框架、弹性薄膜和所述第二隔音结构围成;共振吸声体,设置在所述弹性薄膜上。本发明可以有效提高轿厢隔声性能,降低外部噪声通过轿厢进入轿厢内部。
