The invention provides a trolley with an automatic braking function, and relates to the field of trolleys. The trolley comprises a trolley frame and a storage basket arranged on the trolley frame, and universal wheels and an automatic brake mechanism are arranged at the bottom of the trolley frame; the automatic braking mechanism comprises a rotating shaft, a hydraulic cylinder and two vertical plates, the two vertical plates are arranged at the bottom of the frame at intervals, sliding grooves are formed in the vertical plates, the rotating shaft is arranged between the two sliding grooves in a penetrating mode, the two ends of the rotating shaft are each provided with an auxiliary wheel, and the auxiliary wheels and the rotating shaft rotate synchronously. A push rod of the hydraulic cylinder is movably connected with the rotating shaft, and the hydraulic cylinder pushes the rotating shaft to slide in the extending direction of the sliding groove. An ultrasonic sensor used for detecting obstacles is arranged on the front portion of the vehicle frame, data collected by the ultrasonic sensor are transmitted to a controller through a signal line, and the controller controls stretching and retracting of the hydraulic cylinder. The trolley has the effect of automatically braking and stopping the trolley.
