A multi-purpose vehicle varying a size of a screen is provided to improve energy efficiency by charging a solar cell with the sunlight and to increase a visual effect by regulating an area of a display panel in consideration of the road condition and the transmitted image. In a multi-purpose vehicle(1), a display main panel and a display auxiliary panel(8) are installed at the lateral side and the rear part of the vehicle and connected to each other to transmit an image. A horizontal cylinder(7) and a vertical cylinder(6) are positioned in the vehicle and combined with the back side of the display main panel to move the display main and auxiliary display panels horizontally and vertically. A collection plate is installed at the upper part of the vehicle to convert the sunlight into electric energy. An inclination cylinder is coupled with the back side of the collection plate to adjust the inclination angle of the collection plate. Outriggers(2) are installed at four sides to prevent overturning and vibration when the vehicle stops. An auxiliary power generation device(18) disposed in the vehicle uses a solar cell and an auxiliary power generator. A hydraulic controller drives the vertical and horizontal cylinders, the inclination cylinder, and the outriggers. |
