The invention belongs to the technical field of elevator cars, and particularly relates to an elevator noise reduction car which comprises a car body, a sound absorption plate, a damping assembly and a buffering assembly. A cavity is formed in the compartment body, and a set of sound insulation sponges are symmetrically and fixedly connected to the side, away from the cavity, of the compartment body. The pair of acoustic panels is symmetrically and fixedly connected to the side wall, close to one side of the cavity, of the compartment body. The damping assembly is arranged in the cavity; the buffer assembly is arranged between the sound absorption plate and the sound insulation sponge; the damping assembly comprises a piston cylinder, a piston rod and a top plate; the multiple sets of top plates are symmetrically and fixedly connected to the side wall of the sound absorption plate. The multiple sets of piston cylinders are fixedly connected to the inner side wall of the compartment body. The piston rod is fixedly connected to the side wall of the top plate and is in sliding fit with the piston cylinder; according to the elevator, the sound absorption plate and the damping assembly are arranged and matched with each other, so that noise sound waves generated in the closed car body are attenuated, the reflection frequency of the sound waves is reduced, the riding comfort is improved, and the riding safety of the elevator is improved.

    本发明属于电梯轿厢技术领域,具体的说是一种电梯降噪轿厢,包括厢体、吸音板、减震组件和缓冲组件;所述厢体内部开设有空腔,其远离空腔一侧对称固接有一组隔音海绵;一对所述吸音板对称固接在靠近空腔一侧厢体侧壁上;所述减震组件设置在空腔内部;所述缓冲组件设置在吸音板和隔音海绵之间;所述减震组件包括活塞缸、活塞杆和顶板;多组所述顶板对称固接在吸音板侧壁上;多组所述活塞缸固接在厢体内侧壁上;所述活塞杆固接在顶板侧壁上,且与活塞缸滑动配合;通过设置吸音板和减震组件,依靠其相互配合,使得密闭厢体内产生的噪音声波得到了衰减,并减缓声波的反射频率,进而提高了乘坐舒适度,并提高了电梯乘坐的安全性。
