The utility model relates to the technical field of automobile driving systems, in particular to an electric
tail gate driving mechanism with an overload protection function and a
pickup truck comprising the electric
tail gate driving mechanism, the electric
tail gate driving mechanism comprises a motor
assembly and an output part, the motor
assembly is used for driving the output part to rotate, and the electric tail gate driving mechanism further comprises an overload protection device, the overload protection device is arranged between the motor
assembly and the output part, and when the output torque of the motor assembly exceeds a set value, the torque, acting on the output part, of the overload protection device is interrupted; otherwise, the method is not interrupted. According to the overload protection device, the motor assembly can be protected, when the required torque exceeds a set value due to overload or mechanical faults, the torque transmitted by a
transmission system is limited in a slipping mode, and when the overload situation disappears, connection is automatically recovered, so that mechanical damage is prevented, and expensive shutdown loss is avoided.
