Abstract

The invention provides an aircraft cabin door opening device, which comprises an electric push rod and a cabin body; one side of the cabin is an mounting opening, and the other three sides are provided with bulkheads; an upper mounting seat is arranged on the inn walls of the bulkheads, and a hatch door is connected with the mounting opening; low mounting seats are arrange on the upper and lower ends of the hatch door; one sides of the lower mounting seats are sequentially provided with rotating seats and fixing seats, and the fixing seats are connected with the rotating seats through rotatingshafts; one end of the electric push rod is connected with the upper mounting seat, and the other end is connected with the lower mounting seats. The invention adopts a simple structure and a lightweight structure, so that the opening time of the hatch door is shorter than 4-5s, and the maximum angle at which the hatch door can be opened is 90-110 degrees, and the quick opening, closing and larger opening angle of the hatch door can be realized.

Description

technical field [0001] The invention relates to an aircraft cabin door opening device, which belongs to the technical field of mechatronics. Background technique [0002] In order to realize the opening and closing of the hatch, the hatch drive system is composed of: power source, hatch mechanism, synchronization mechanism, spoiler mechanism, upper lock and lower lock, etc. The function of each part: the function of the power source is to drive the hatch mechanism and the synchronization mechanism to provide the power required for movement; the drive mechanism is to realize the opening and closing of the hatch; the synchronization mechanism is to ensure the synchronization of the hatch movement; The role of the spoiler mechanism is to ensure that the spoiler follows the movement during the movement of the hatch; the upper lock and the lower lock are to ensure that the hatch can be fixed in the closed and open positions respectively. [0003] The driving methods of the door ...
