[0030] The specific usage scenario of this embodiment is as follows: The bottom plate 230 is provided for installing the air pump 240, and the air pump 240 is provided for inflating the inside of the airbag 210. Thus, after the airbag 210 deflates through the pressure relief valve 220, the air inside the airbag 210 can be replenished, enabling the airbag 210 to maintain the function of buffering and anti-collision around the chassis 100 of the trolley, improving the protection of the chassis 100 of the trolley.

When the driverless trolley is running, the airbag 210 plays a protective role around the chassis 100 of the trolley. When the chassis 100 of the trolley is collided with from all around, after the surface of the airbag 210 is collided, the anti-collision rubber block plays a wear-resistant role. After being squeezed, the pressure inside the airbag 210 increases and the gas will be released through the pressure relief valve 220, thereby preventing the airbag 210 from bursting due to excessive pressure. By releasing the gas, the impact force on the periphery of the chassis 100 of the trolley during the collision is reduced, thereby improving the protection of the driverless trolley and enhancing the practicality of the equipment in use.
