The sliding ceiling is additionally arranged in front of the platform of the passenger boarding ladder, so that the windproof and rainproof requirements of the top and the two sides of the passenger ladder platform entering and exiting a cabin door can be met, the use requirements of passengers in front of the cabin door can be met, meanwhile, the width of the ceiling does not exceed the width of a whole vehicle, the front-back sliding
stroke is large, the weight is low, use difficulty is avoided, and the cost is controllable. Besides, the shape of the ladder body and the shape of the awning are matched with each other, the overall appearance is coordinated, in addition, the sliding ceiling can adopt two operation
modes of electric driving and manual driving, and manual locking is needed after the sliding ceiling is driven, so that the use standard requirements of
