[0003] At present, there is a Chinese patent with the name of elevator car wall and the publication number of CN102887417A. It includes a rectangular metal frame, and metal plate walls are fixedly installed on the two sides of the frame. Sound insulation materials are filled between the metal plate walls, and the thickness of the sound insulation materials can make them contact with the metal plate walls on the two sides of the frame. The main purpose is to fill sound insulation materials in the hollow structure surrounded by the metal frame and the metal plate walls as the car wall. However, the area of the metal plate wall is large, and the sound insulation materials inside are soft. When the metal plate wall is subjected to external force, the center part of the metal plate wall lacks support and is easy to be deformed.
