[0023] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0024] See appendix Figure 1 As shown, a soundproof room includes a wall 1, a top plate, a bottom plate 3, a material door 2, a personnel passage door 4, and an interior partition 6. The wall is composed of a four-sided enclosed wall panel. The top plate is sealed and fixedly connected to the upper end of the wall, and the bottom plate is fixedly connected to the lower end of the wall, so that the wall, top plate, and bottom plate enclose and form a rectangular soundproof room main structure. The external dimensions of the soundproof room in this embodiment are 3600mm wide * 9600mm long. Material doors are installed at both ends of the wall along its length. When the material doors are open, the chair trays to be tested can enter and exit the soundproof room. When the material doors are closed, they can isolate internal and external noise.

[0025] See appendix Figure 2 As shown, room partitions 6 are spaced along the length of the wall, dividing the soundproof room into multiple independent test chambers. The inner test chamber is 2500mm high. In this embodiment, three room partitions are provided, thereby dividing the soundproof room into four independent test chambers.

[0026] Five collaborative robots were installed in the test room. The collaborative robots were Yuejiang CR10 robots with a load of 10Kg, a repeatability accuracy of ±0.03mm, a speed of 4m / s, and an arm span of 1300mm.

[0027] like Figure 3As shown, the wall is made of multi-layer composite panels, and all wall materials are made of flame-retardant materials. From the inside out, the wall consists of a galvanized perforated plate 101, a fire-retardant layer 102, a first sound-absorbing material layer 103, a first sound-insulating material layer 104, a second sound-absorbing material layer 105, a second sound-insulating material layer 106, a third sound-absorbing material layer 107, a third sound-insulating material layer 108, a sound-insulating resonance frame layer 109, and a cold-rolled steel plate 110. The fire-retardant layer is made of fire-resistant glass cloth. The first, second, and third sound-absorbing material layers are made of fiberglass wool. The first and second sound-insulating material layers are made of PS medium-density fiberboard, and the third sound-insulating material layer is made of double-layer XK sound-insulating board. The outer surface of the cold-rolled steel plate is coated with a 2mm thick powder coating. The wall thickness is no more than 300mm.

[0028] See appendix Figure 4 As shown, there are eight 500mm*500mm transparent observation windows distributed around the perimeter of the wall, with sound-absorbing cotton lining at a density of 40 kg / m³. 3 The surface is decorated with perforated sound-absorbing panels.

[0029] See Figure 5 As shown, to prevent low-frequency vibration noise from entering the test chamber through the ground, the base structure includes a base frame, steel plates, and steel spring vibration isolators 7. The steel spring vibration isolators 7 are supported on the workshop floor foundation. The upper end of the steel spring vibration isolators 7 is fixedly supported by the base frame. A 6mm thick steel plate is laid on the base frame, and environmentally friendly rubber pads and carpets are laid on the surface of the steel plate to effectively block the transmission of low-frequency vibration noise. The steel spring vibration isolators 7 are existing technology and are not described in detail in this application. The appropriate damping specifications can be selected as needed. The height of the steel spring vibration isolators 7 can be finely adjusted to ensure a uniform height of the soundproof room's base.

[0030] See Figure 6 As shown, the material door is a double magnetic control soundproof door with double-layer linkage. Its dimensions are 1200mm wide * 1400mm high. The material door is designed as a single door structure that opens and closes on both sides. The door lock is an electromagnetic door lock, which is installed on the top of the door and automatically unlocks when the power is off, ensuring that personnel are not locked inside. The door frame is sealed and vibration-damped at the wall connection to prevent sound from entering the room through gaps between the door frame and the wall.

[0031] See Figure 7 As shown, to facilitate the entry and exit of operating personnel, each test room has a personnel access door on its corresponding wall. The personnel access door is a double-layered soundproof door that opens outwards. The size of the personnel access door is 750mm*2000mm, and the sound insulation reaches more than 40 decibels. The inner door is locked with a latch on the inside. Both the inner and outer double-layered soundproof doors adopt a three-layer sealing structure. The door seams are sealed with environmentally friendly and highly absorbent sound insulation material to ensure the best sound absorption and insulation effect.

[0032] See Figure 8 As shown, the room partition includes a fixed partition panel and a sliding partition door. A square channel is located in the center of the fixed partition panel, and the sliding partition door, installed in the square channel, can close the channel, thus creating an effective partition within the soundproof room. The fixed partition panel is lined with rock wool. The sliding partition door is driven by a cylinder and uses a 5mm thick crystal curtain. The sliding partition door opens or closes as the seat tray moves in and out.

[0033] Finally, it should be noted that the above-described embodiments are merely specific implementations of the present invention, used to illustrate the technical solutions of the present invention, and not to limit it.
