At this time, the fixed plate 13 is a rigid fixed structure. Through the set fixed plate 13 and the viscous damping plate 12 are in viscous contact, the deformation caused by the vibration of the surface of the viscous damping plate 12 is reduced, thereby reducing vibration and reducing the spread of noise. When the vibration continues to propagate, the pressure plate 14 will swing, and the spring column 15 below is set to make the The transmitted vibration is partially consumed by the spring column 15. The spring column 15 is provided to reduce the vibration generated by the vehicle floor 1, thereby achieving the effect of reducing noise. The U-shaped fixing plate 17 is fixedly connected to the base 16. The stability of the equipment is increased by the first fixing bolt 18.

The combination of the viscous damping plate 12, the fixing plate 13, and the spring column 15 is provided to reduce the bottom noise layer by layer, thereby achieving the effect of sound insulation. When the equipment is working, the floor 25 will be subjected to pressure from above. The multiple sets of fixing piles 2 and the top plate 26 can support the floor 25 to increase the stability of the floor 25. The X-shaped fixing plate 28 is provided to make the floor 25 The pressure can be distributed to the U-shaped fixing plate 17 and discharged downward through the U-shaped fixing plate 17, thereby improving the practicability of the equipment and increasing the stability of the equipment structure. The contact area between the fixing pile 2 and the vehicle floor 1 can be increased by setting the first fixing plate 21. The first fixing plate 21 is bolted to the vehicle floor 1 by the second fixing bolt 22, thereby increasing the stability of the fixing pile 2 during the use of the equipment. When the equipment is working, the temperature at a higher position inside the car will be higher than the temperature close to the ground. At this time, the temperature distribution inside the car is uneven, and the heating wire 3 inside the floor 25 will continue to heat up. The floor 25 can be heated by the heating wire 3, and the heat is discharged upward through the floor 25, thereby increasing the temperature inside the vehicle from the bottom. When the equipment is installed, an external switch is used 33 directly controls the heating of individual floors 25, and can also control the temperature of a certain area through the series parallel interface 34. The external switch 33 and the parallel interface 34 can be used to increase the use scenarios of the settings and increase the practicality of the equipment. When the equipment is working, the noise transmitted from the vehicle bottom plate 1 is reduced layer by layer, and the sound insulation board 4 and the sound absorbing board 41 are set to enhance the internal sound insulation effect. When installing the equipment, when connecting multiple sets of parallel interfaces 34, multiple sets of wires will be generated. The fixed wire trough 5 can be used to fix the lines inside the fixed wire trough 5. The fixed wire trough 5 is convenient for the staff to maintain the equipment. When the equipment is working, the pressure plate 14 will move up and down through the spring column 15.By setting the limit plate 6, the pressing plate 14 can be more stable when working. The setting of the limit plate 6 can make the pressing plate 14 run more stably and reduce the failure rate of the equipment. When the equipment is working, the floor 25 will continue to generate heat, and the heat will radiate from the floor 25 to the surroundings.
