Problems solved by technology

[0003] The existing bracket structure belongs to the symmetrical distribution centered on the pilot, which occupies a large installation space and has high requirements for the layout of the cockpit of the aircraft, which is not conducive to the installation of the combined glass in the cockpit of the aircraft; at the same time, the structure of the locking mechanism is also relatively complicated. The reliability and security of the lock is not high

Embodiment Construction

[0021] Embodiments of the bracket assembly for the combination mirror of the airborne head-up display Figure 3~5 As shown: it includes the mounting support 7 for being installed on the corresponding body and the combination mirror mounting frame which is rotatably assembled on the mounting support 7 and has a stowed position and an unfolded position. The frame is positioned at the locking structure of the stowed position B and the unfolded position A. The locking structure includes a positioning wheel 8 arranged on the mounting support 7, axially consistent with the rotation axis of the rotating arm 9, and coaxially rotating with the positioning wheel. Cooperating rotating arm 9, the front end of rotating arm 9 is equipped with glass frame, and glass frame comprises the glass bearing that is used for installing corresponding combination glass 10 that is rotatably arranged on rotating arm 9 front end. The outer circumference of the positioning wheel 8 is provided with position...

Abstract

The invention relates to a support assembly for the locking structure of a rotation arm and the combined mirror of an onboard head-up display. The support assembly comprises a positioning wheel and a rotating arm which are provided with positioning slots, a positioning pin which is embedded in each positioning slot in a radial direction and a locking mechanism which is used for driving the positioning pin to embed into and take off a corresponding positioning slot are arranged on the rotating arm, the locking mechanism comprises a crank slide block mechanism, a slide block in the crank slide mechanism is matched with the positioning pin in a transmission way, a crank is provided with a locking position and a delocking position during a rotation process, a plane formed by the hinged axis of the connecting rod and the slide block in the crank slide block mechanism as well as the rotating axis of the crank is a reference plane, the hinged axis of the crank and the connecting rod is positioned on the reference plane or on one side of the reference plane, and when the hinged axis of the crank and the connecting rod is positioned on one side of the reference plane, a limit mechanism for enabling the crank to be in a locking position is arranged on the rotating arm. The invention provides the locking structure of the rotating arm used in assembly of the combined mirror of the head-up display on a transportation aircraft, and the locking structure is reliable in locking.

Description

technical field [0001] The invention relates to a locking structure of a rotating arm for a transport aircraft and a bracket assembly for a combination mirror of an airborne head-up display. Background technique [0002] When the pilot is driving a transport aircraft, he needs the corresponding aircraft head-up display to transmit some important flight information to the pilot. The aircraft head-up display includes a host and a combination mirror for reflecting flight information. The combination mirror is arranged directly in front of the pilot. The specific structure of existing aircraft head-up display combination mirror and support is as attached Figure 1-2 As shown: the fly includes a combined glass 1 reflecting information, the combined glass 1 is installed on the body through a bracket assembly, and the bracket component includes a combined mirror mounting frame 2 for installing the combined glass, an operating handle 3, a rotating shaft 4, a locking mechanism 5 and a...
