The working principle and the working flow of the utility model are as follows: when the solar energy heat absorption device is used, sunlight irradiates on the roof body 1, the heat absorption plate 6 contacted with the roof body 1 absorbs heat on the roof body 1 and transmits the heat to the elastic air bag 3, gas in the elastic air bag 3 is heated and expanded, when the pressure of the gas is increased to be larger than the acting force of the reset spring 403, the gas pushes the check valve ball 402 to be separated from the vent hole 404, the gas is discharged to the outside of the roof body 1 through the vent hole 404, the check valve cavity 405 and the air pipe 5, so that constant air pressure in the elastic air bag 3 is ensured, the elastic air bag 3 always plays a role in buffering the roof 1, and the roof 1 is prevented from being deformed due to impact of foreign matters or placement of heavy objects; meanwhile, the elastic air bag 3 also plays a good role in heat absorption and heat dissipation. The hollow slab 8 is horizontally and fixedly connected on the inner wall of the top plate body 1, and the heat insulation material 9 filled in the hollow slab plays a role in heat insulation and heat preservation of the top plate body. The reinforcing bracket 10 fixedly connected below the hollow plate 8 plays an auxiliary reinforcing role on the top plate body 1 and prevents the top plate body 1 from deforming. The wood strips 11 between the hollow plates 8 and the reinforcing brackets 10 reduce the heat transfer between the hollow plates 8 and the reinforcing brackets 10, so that the temperature inside the caravan is suitable.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
