A gravity-pressurizing-type automatic water supply vehicle washing device comprises a pressurizing box, a water storage tank and a spray-washing device. The pressurizing box is of a sealed structure, a communicating pipe is arranged between the pressurizing box and the water storage tank, the spray-washing device comprises a water spraying pipe and a nozzle connected on the water spraying pipe, the nozzle is positioned on the outer side of the pressurizing box, the lower end of the water spraying pipe is communicated with the pressurizing box, and a check valve is arranged on each of the water spraying pipe and the communicating pipe; the pressurizing box comprises a top plate which is flexibly connected with the side wall of the depressurizing box, a plurality of springs are arranged in the pressurizing box vertically, and the upper end and the lower end of each spring are connected on the top plate and at the bottom of the pressurizing box respectively. After entering the water storage tank, water automatically flows into the pressurizing box by applying a communicating device principle, water level in the pressurizing box is flush with that in the water storage tank, the water in the pressurizing box is pressurized by utilizing dead weight of a vehicle, the check valves are adopted to prevent the water in a water tank to flow back into the water storage tank, and the water in the pressurizing box realizes spray-washing effect through the spray-washing device under action of water pressure.
