Abstract

The invention discloses a cabin door actuating mechanism, which comprises a guide rod (1), a sliding block (2), a guide rod supporting rod (3), a crank (4), a crank supporting rod (5), a support (6),a sliding block rotary shaft (7), a crank rotary shaft (8) and a guide rod rotary shaft (9). The guide rod (1) and a cabin door (10) are rigidly connected into a whole, and one ends of the guide rod supporting rod (3) and the crank supporting rod (5) are fixed to the support (6), wherein the relative positions of the guide rod (1), the sliding block (2), the guide rod supporting rod (3), the crank(4), the crank supporting rod (5), the sliding block rotary shaft (7), the crank rotary shaft (8) and the guide rod rotary shaft (9) meet the preset relation. According to the cabin door actuating mechanism, the components are few, and conciseness and reliability are achieved; and by adjusting the relative positions and the connecting relation of the guide rod and the cabin door, the kinetic characteristic of actuating of the equipment cabin door can be adjusted, and good adaptability is achieved.

Description

technical field [0001] The invention belongs to the field of aviation electromechanical technology, and in particular relates to a cabin door actuating mechanism. Background technique [0002] Door actuation mechanisms are widely used in aircraft and other carrier equipment, and there are various forms according to the requirements of door shape, opening and closing positions, and motion characteristics. [0003] Some equipment requires that the door gradually accelerates after opening at the selected minimum speed, and slows down before reaching the maximum opening position or opens at the maximum speed; during closing, the door starts to move at the maximum speed and then gradually decelerates until it is closed. Doors close when accelerating or reaching minimum speed. However, the existing hatch door actuating mechanisms either cannot realize the above functions, or have many components and complex structures, so the actions are unreliable.
