The invention belongs to the field of mobile robots and relates to a four-wheel damping chassis for a mobile robot. The chassis comprises a bottom plate, driving wheels, driving motors, flange frames,limiting pieces, sliding rods and universal wheels; the front end and the rear end of the bottom plate are each provided with one universal wheel; the left side and the right side of the bottom plateare each provided with one flange frame; the driving motors are arranged on the flange frames respectively; the driving motors are connected with the corresponding driving wheels; each flange frame is in the shape of a Chinese character "ou"; the sliding rods are arranged on outward-protruding parts on the two sides of each flange frame; the lower ends of the sliding rods penetrate through the outward-protruding parts on the corresponding sides of the flange frames and then are fixedly connected with the bottom plate; nuts are arranged at the upper ends of the sliding rods; the sliding rods are sleeved with damping springs; the damping springs are arranged between the outward-protruding parts and the nuts; the limiting pieces shaped like Chinese character "tu" are arranged on the bottom plate; and the flange frames are arranged in the limiting pieces. With the chassis of the invention adopted, the mobile robot can run stably, and the vibration damping capability of the mobile robot isimproved.
