Mobile chassis mechanism and inspection robot comprising same

The invention provides a mobile chassis mechanism and an inspection robot comprising the same. The mobile chassis mechanism comprises a chassis unit, a battery storage unit and a hardware module fixing unit, wherein the battery storage unit is arranged above the chassis unit and used for storing batteries; and the hardware module fixing unit is arranged above the battery storage unit and is used for fixedly installing a hardware module. By arranging the mobile chassis mechanism of a three-layer structure for the inspection robot, sufficient space is reserved for arrangement of hardware equipment such as a battery driver, expensive equipment such as a controller and a main control board is physically isolated from a dangerous source, namely, the battery, the safety is guaranteed, and the purpose that the gravity center is lowered by placing a heavy object on the bottom layer is achieved through the layer structure; and meanwhile, three rows of opposite wheel structures are arranged on the chassis unit, the eff
