The invention discloses a recreational vehicle carriage expansion type chassis capable of automatically ascending and descending, and relates to the technical field of recreational vehicle carriage expansion type chassis. The expansion capacity of the chassis is improved in the vertical direction. The chassis specifically comprises a frame and three connecting seats, a recreational vehicle chassisis fixed to the outer wall of the top of the frame through bolts, an expansion chassis is slidably connected to the inner wall of one side of the recreational vehicle chassis, U-shaped sliding grooves are formed in the inner walls of the two sides of the expansion chassis, and pulleys are rotatably connected to the outer walls of the two sides of the three connecting seats; the outer walls of thecircumferences of the six pulleys rotate on the inner walls of the two U-shaped sliding grooves correspondingly, the outer walls of the two sides of one connecting base are rotationally connected with two second connecting rods correspondingly, and the outer walls of one sides of the other two connecting bases are rotationally connected with two first connecting rods correspondingly. By arrangingthe pulleys, the three connecting bases can be slidably connected to the inner walls of the two U-shaped sliding grooves conveniently, and the first connecting rod and the second connecting rod can be folded and unfolded by sliding the connecting bases.
