[0032] The following is combined with Figure 1 to Figure 2 This application is described in further detail.

[0033] The present application provides a cockpit top emergency door, comprising: a slide rail 1, a door body structure 2 and a door drive assembly.

[0034] Specifically, Figure 1-2 As shown, the slide rail 1 is fixedly mounted on the fuselage frame, and a support portion is provided on the slide rail 1. The slide rail 1 is used to control the movement posture of the cabin door and the locking support of the cabin door in the open and closed positions. The door structure 2 is slidably mounted on the slide rail 1, and support rods 3 are respectively installed on both sides of the door structure 2. When the door structure 2 slides to the open position, the support rods 3 engage and lock with the support portion.

[0035] The door drive assembly includes a handle 4, a rotating shaft 5, a rocker arm 6 and a connecting rod 7, wherein the handle 4 is installed on the inner side of the door body structure 2; the two ends of the rotating shaft 5 are respectively connected to the support rod 3 on the corresponding side; the rocker arm 6 is installed on the rotating shaft 5; one end of the connecting rod 7 is connected to the handle 4, and the other end is connected to the rocker arm 6; the handle 4, the rotating shaft 5, the rocker arm 6 and the connecting rod 7 form a four-bar mechanism, and the rotating shaft 5 is driven to rotate by the handle 4, which drives the support rod 3 to rotate, thereby realizing the opening and closing of the door.

[0036] In a preferred embodiment of the present application, the cockpit top emergency door is installed on the top of the cockpit by arranging the fuselage mouth frame on the top of the cockpit.

[0037] In a preferred embodiment of the present application, two parallel slide rails 1 are provided, and the ends of the slide rails 1 have a limit portion for limiting the sliding position of the door structure 2. Advantageously, in this embodiment, rollers are installed on both sides of the door structure 2, and the door structure 2 is meshed and connected with the slide rails 1 through the rollers. Multiple rollers can be provided along both sides of the door structure 2, which can improve the stability of the cabin door sliding and prevent the cabin door from swinging.

[0038] In the preferred embodiment of the present application, a glass window 8 is installed on the door structure 2. By arranging a large-sized glass window 8, the functional requirements of lighting inside the cabin and observing the outside of the cabin are achieved. In addition, in this embodiment, a sealing strip 9 is installed on the peripheral side of the door structure 2 to achieve the sealing of the emergency door on the top of the cockpit.

[0039] In a preferred embodiment of the present application, the handle 4 is held in position by a tension spring 10 connected to the door structure 2. The tension spring acts as a booster and a safety protection measure, providing a locking force to keep the mechanism closed when the emergency door is closed.

[0040] The cockpit top emergency door of the present application is based on the multi-functional requirements of the door for lighting, ventilation, observation outside the aircraft, escape, safe locking, sealing, etc., as well as constraints such as limited space restrictions. The door body structure 2, door drive assembly, glass window 8, and sealing belt 9 are reasonably arranged, and the door movement trajectory and attitude control are comprehensively optimized. Through the slide rail 1 fixed on the fuselage frame structure, the door movement occupies a small space, the attitude is precisely controlled, and it is reliably locked.

[0041] Compared with the aircraft fixed-axis rotating door or detachable door, the cockpit top emergency door of the present application effectively solves the adverse effect of door movement being limited by space, arranges the mechanism reasonably, meets the requirement of maximizing the visible area of ​​the glass window, effectively saves the cabin space required for door movement, has a simple mechanism, integrated functions, improves safety, and can reduce weight.

[0042] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
