The invention discloses a hand trailer with an automatic braking function. The hand trailer comprises a hand trailer body, a sensing module, a driving module, a control module and a buffering anti-collision module. The driving module drives the hand trailer body to move forwards through a direct current motor and conducts braking through a power-off brake. During working, whether the handle of the hand trailer body is held or not is obtained through the sensing module, and then the driving module is controlled through the control module, so that when the handle of the hand trailer body is held, the hand trailer body is driven to advance, and when the handle of the hand trailer body is loosened, braking is conducted. And the buffer anti-collision module further avoids the safety problem of battery damage caused by collision with stairs when the hand trailer body is released from the hand.

    本发明公开了一种自动刹车的手拖车,包括手拖车本体、感应模块、驱动模块、控制模块和缓冲防碰模块。所述驱动模块通过直流电机驱动手拖车本体前进,并通过断电制动器来进行制动。工作时,本发明通过感应模块获得手拖车本体的把手是否被握住,进而通过控制模块来控制驱动模块,使得手拖车本体的把手被握住时驱动手拖车本体前进,手拖车本体的把手被松开时进行制动。缓冲防碰模块进一步避免手拖车本体脱手时碰撞楼梯导致电池损坏的安全问题。
