This utility model discloses a motorhome chassis frame, belonging to the field of motorhome manufacturing technology. The utility model includes a chassis frame, spring shock absorbers, and a row of reinforcing ribs. The two ends of the row of reinforcing ribs are respectively connected to the interior of both sides of the chassis frame. Mounting plates are provided at both the front and rear ends of the chassis frame. Rectangular grooves are formed within the mounting plates, and support seats fit within these grooves. The support seats have openings within them. The two ends of the spring shock absorbers are respectively connected to the rectangular grooves and the tops of the support seats. This utility model, through the sliding cooperation structure of the slider and the groove, combined with the elastic support of the spring shock absorbers, allows the support seats to adaptively adjust in the vertical direction, effectively absorbing vibration and impact energy during vehicle operation. When the wheels encounter bumps, the support seats drive the slider to slide up and down within the groove, causing the spring shock absorbers to compress or extend, converting the impact force into elastic potential energy and releasing it slowly. This significantly reduces the vibration intensity transmitted to the frame and extends the service life of the chassis frame.
