Description

Rocker arm type electric door mechanism Technical Field The application belongs to the field of aircraft cabin door lock mechanism design, and particularly relates to a rocker arm type electric door mechanism. Background The single rocker arm type electric door mechanism and the proximity sensor are electric door signal trigger acquisition devices, and can realize non-contact signal trigger. The traditional single rocker-arm electric door mechanism and the proximity sensor can only monitor the motion state of one part, and cannot monitor the relative motion state of two parts. It is therefore desirable to have a solution that overcomes or at least alleviates at least one of the above-mentioned drawbacks of the prior art. Disclosure of Invention The application aims to provide a rocker arm type electric door mechanism, which solves at least one problem existing in the prior art. The technical scheme of the application is as follows: A rocker arm electric door mechanism comprising: The support is fixedly arranged on the machine body; The rocker arm comprises a triangular rocker arm and a straight rocker arm, the triangular rocker arm comprises an upper rocker arm part, a middle rocker arm part and a lower rocker arm part which are integrally formed, wherein, The upper rocker arm part and the upper part of the straight rocker arm are hinged with the support, a first adjusting bolt is arranged on the upper rocker arm part, and the head part of the first adjusting bolt is abutted against the support; The middle rocker arm part is provided with a first connecting part and a second connecting part which are perpendicular to each other, the first connecting part is connected with the support through a long tension spring, and the second connecting part is connected with the middle part of the straight rocker arm through a short tension spring; the lower rocker arm part is provided with a mounting groove, an electric door is mounted in the mounting groove, a second adjusting bolt is mounted at the lower part of the straight rocker arm, and the second adjusting bolt corresponds to the electric door in position; The triangular rocker arm can swing backwards under the pushing of the rocker arm of the lock mechanism, and the straight rocker arm can swing forwards under the pushing of the cabin door stop pin.
