The invention provides a novel lifting skylight system structure and a vehicle, a skylight glass assembly is arranged on a roof through a frame assembly, the skylight glass assembly is connected with the frame assembly through a hinge assembly, a folding tent is arranged between the skylight glass assembly and the frame assembly, and the tent is of a folding closed-loop structure. Two ends of the connecting rod are respectively clamped with the frame assembly and the skylight glass assembly. Under the control of the control module, the skylight glass rotates and ascends and descends around the hinge assembly relative to the roof under the action of the lifting mechanism, when the skylight glass is opened, the folding tent is unfolded to expand the space in the vehicle, meanwhile, the effects of keeping out wind and rain and preventing sand dust and mosquitoes from entering the vehicle are achieved, and when the skylight glass is closed, the folding tent is unfolded to expand the space in the vehicle. Due to the pleated design of the tent, the tent can be stored in the frame assembly more easily. A locking mechanism is further arranged in the frame assembly and used for achieving locking and unlocking when the skylight is in the closed state.
