Abstract: Disclosed are a chassis of an automated guided vehicle and an automated guided vehicle. The chassis includes a front frame (1) and a rear frame (2) that are engaged with each other in a hinged joint manner, so as to allow a relative folding between the rear frame (2) and the front frame (1).

Moreover, the damping device (3) restricts the folding angle of the front frame (1) and the rear frame (2) to prevent that the relative folding angle of the front frame (1) and the rear frame (2) is too large to realize the transport function, and damps the folding angle for reducing vibration.
