when the outer handle is used for opening the door, the handle lock button is pressed to unlock the outer handle. After the handle lock hook is separated from the pin shaft of the handle box, the outer handle shaft slides outwards under the action of the pushing force of the pressure spring. At this time, the spline on the outer handle shaft engages the spline groove on the outer handle rocker arm. The extension amount of the outer handle is about 50mm, and the spline end face of the handle shaft is axially limited. After the outer handle stretches out to the right place, the connecting rod mechanism is driven by rotating the outer handle, so that the lock shaft is driven to rotate, and the opening of the cabin door mechanism is completed.
After the cabin door is closed in place by using the outer handle operating mechanism, the outer handle is pressed inwards to lock the handle lock, and the outer handle is locked in the handle box.
The foregoing is merely specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions easily conceivable by those skilled in the art within the technical scope of the present application should be covered in the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
