Heat insulation and sound absorption board for vehicle roof, vehicle roof and vehicle

The utility model provides a heat insulation and sound absorption board for a vehicle roof, the vehicle roof and a vehicle, the heat insulation and sound absorption board for the vehicle roof comprises a base plate and a heat insulation layer arranged on the outer side of the base plate, the heat insulation layer is provided with a plurality of through holes, and a cavity capable of being communicated with the through holes is arranged in the base plate. And the through holes are communicated with the corresponding cavities to form sound-absorbing resonant cavities. According to the heat insulation and sound absorption plate for the vehicle ceiling, the heat insulation effect of the vehicle ceiling can be improved through the heat insulation layer, the sound absorption resonant cavity is formed through the through holes in the heat insulation layer and the cavity in the base plate, sound energy is converted into heat energy in the process that sound waves move back and forth in the sound absorption resonant c
