The invention relates to a mobile robot chassis and discloses a mobile robot chassis and a suspension structure thereof, and the suspension structure comprises a front suspension mounting seat, a rear suspension mounting seat and two rocker arm mounting seats which are fixedly connected to a chassis bottom plate; the device further comprises two rocker arms, two rocker arm dampers, four spring assemblies and a vehicle body damper. The rocker arms are hinged to the rocker arm mounting bases. The front suspension arm and the driving wheel suspension arm are hinged with the front suspension mounting seat, and the rear suspension arm is hinged with the rear suspension mounting seat; the upper end of the spring assembly is hinged to one end of the rocker arm, and the lower end is fixedly connected to the suspension arms. The upper and lower ends of the rocker arm damper are respectively hinged between the rocker arm and the front and rear suspension arms; the upper end of the vehicle body damper is hinged with the chassis bottom plate, and the lower end is hinged with the rear suspension arm; the mobile robot chassis comprises the suspension structures arranged on the left side and the right side of the chassis bottom plate. The chassis can achieve center steering, the obstacle crossing capacity, the shock absorption capacity and the stability of the chassis are improved, and the chassis is particularly suitable for being used by a mobile robot in the outdoor environment.
