Actuating Assembly, and Fuel Filler or Charging Inlet Flip Assembly

The present disclosure relates to an actuating assembly and a fuel filler or charging inlet flip assembly. The actuating assembly comprises a driving gear and a transmission gear. The transmission gear is configured to be capable of rotating in a first direction to open the flip and in a second direction to close the flip, driven by the driving gear. An outer periphery of the driving gear is provided with a first outer periphery portion and a second outer periphery portion, the first outer periphery portion is provided on one side of the second outer periphery portion in a circumferential direction, the first outer periphery portion comprises a plurality of driving teeth, the second outer periphery portion comprises a driving gear abutting portion. The actuating assembly can allow for a reduced machining accuracy, and thus allow for a smoother engagement of the driving gear and the transmission gear.
