Fuente: WIPO "circular economy" The invention discloses a compartment roof for sensitively controlling a tarpaulin for a commercial vehicle. The compartment roof comprises a roof body, wherein the roof body is formed by fixedly connecting an upper roof, a lower roof and a rubber interlayer between the upper roof and the lower roof, wherein a solar panel is arranged on the outer surface of the upper roof; a high mounting bracket and a low mounting bracket are separately arranged at the left end and the right end of the upper roof; a first rotating shaft and a second rotating shaft are separately and rotationally connected onto the high mounting bracket and the low mounting bracket; the compartment roof further comprises the tarpaulin; one end of the tarpaulin is fixedly attached to the first rotating shaft; a stay cord wound on the second rotating shaft is fixedly connected to the other end of the tarpaulin; when the stay cord is tightened, the tarpaulin shields the upper part of the solar panel; a humidity sensor is arranged on the outer surface of the upper roof; a signal of the humidity sensor is transmitted to a controller; the controller is in controlled connection with motors of the first rotating shaft and the second rotating shaft. The roof body disclosed by the invention is formed by compounding multiple layers of structures, so the compressive deformation force can be increased; the compartment roof is also provided with the humidity sensor for sensitively controlling folding and unfolding of the tarpaulin, so that the condition that the solar panel is sprinkled by rainwater is avoided.
