Embodiment Construction

[0050] The invention will be described in detail below by means of exemplary embodiments with reference to the drawings. The following detailed description of the present invention is for the purpose of illustration only, and in no way limits the present invention and its application or use.

[0051] refer to figure 1 ( figure 1 To show a top view of the aircraft according to the invention), the aircraft AC according to the invention may comprise a mobile mechanism MM. As an example, the moving mechanism MM may be a flap assembly 20, in particular a trailing edge flap arranged at the trailing edge of the wing AW. Here, it should be understood that the moving mechanism MM can also be an aileron assembly, a rudder, an elevator, an airbrake, and the like.

[0052] refer to figure 2 ( figure 2 To illustrate a flap assembly and associated fixed structure according to the present invention, the flap assembly 20 may include a flap body 22 and a movable support structure (movab...

Abstract

The invention relates to a detent device, a moving mechanism and an aircraft. According to one aspect of the invention, the detent device (100) which is used for the moving mechanism of the aircraft (AC) is provided. The moving mechanism is connected to a fixing structure (30) of the aircraft to enable the moving mechanism to move relative to the fixing structure, the detent device includes a first detent portion (120) arranged at the moving mechanism and a second detent portion (140) arranged at the fixing structure, and the first detent portion is suitable for abutting against the second detent portion to limit the motion range of the moving mechanism through the detent device when a drive connecting structure of the moving mechanism loses efficacy. At least one of the first detent portion and the second detent portion includes a buffering region (BR) which is produced by changing a mesoscopic structure and has decreasing density to be suitable for reducing live load generated by thecollision of the first detent portion and the second detent portion. According to the detent device, the moving mechanism and the aircraft, and the detent device with improved buffering performance can be easily and reliably formed.

Description

technical field [0001] The present invention relates to a stop device, a movable mechanism comprising the stop device and an aircraft comprising the movable mechanism, and more particularly to a stop capable of reliably reducing the dynamic load at the time of impact in the event of failure of the driving connection structure of the movable mechanism device. Background technique [0002] In an aircraft, such as an airplane, there are many different moving parts for carrying out respective functions. For example, these movable parts include various movable airfoils arranged on the wings, such as flaps used to obtain greater lift and better controllability at lower speeds (flaps can be divided into inner flaps and outer flaps Wings can also be divided into leading edge slats and trailing edge flaps, etc.), ailerons for controlling the lateral attitude of the aircraft, and airbrakes for increasing drag to reduce the speed of the aircraft, etc. [0003] In use, there is a poss...
