Abstract

The invention relates to the technical field of opening and closing of cabin doors of helicopters, in particular to an opening and closing mechanism, a lock and a helicopter. The opening and closing mechanism comprises a lock bracket, a feeler lever, a limit mechanism and a micro switch. The feeler lever is arranged on the lock bracket in a sliding manner; the micro switch is arranged on the lock bracket and positioned on one end of the feeler lever; the limit mechanism is arranged between the feeler lever and the lock bracket and used for limiting the distance at which the feeler lever slide towards a shrapnel of the micro switch, so that the feeler lever is abutted with the shrapnel of the micro switch when the lock bracket is locked in a lock box. According to the invention, the sliding distance, on the lock bracket, of the feeler lever is limited through arranging the limit mechanism, so that a cabin door is precisely controlled to be at the completely closed state when the feeler lever is abutted with the shrapnel, and the control precision is improved.

Description

technical field [0001] The invention relates to the technical field of opening and closing of a helicopter cabin door, in particular to an opening and closing mechanism, a lock and a helicopter. Background technique [0002] Helicopter is mainly composed of body, lift (including rotor and tail rotor), power, transmission and airborne flight equipment. The rotor is generally driven by a turboshaft engine or a piston engine through a mechanical transmission system composed of a transmission shaft and a reducer, or it can also be driven by the reaction force generated by the tip jet. [0003] A helicopter is essentially another aircraft different from an airplane, and its thrust, lift, and control are far behind those of an airplane. The prominent feature of the helicopter is that it can do low-altitude (a few meters from the ground), low-speed (starting from hovering) and maneuvering flight with the same nose direction, especially vertical take-off and landing in a small area...
