AI Technical Summary

Technical Problem

The existing ejection seat's adjustable slide rail requires a large operating force and has poor handling comfort, while the quick-release pin operation is inconvenient to observe and use.

Method used

The design incorporates a steel cable assembly, housing, and unlocking mechanism. By operating the unlocking button, the grip bar slides out under the action of a long spring. The stop pin of the steel cable assembly inserts into the limiting hole to control the slide rail angle. Combined with the force-saving lever structure and synchronous unlocking mechanism, it reduces operating force and improves comfort.

Benefits of technology

It enables effortless operation of the ejection seat via an adjustable attitude rail, improving operational comfort and convenience, reducing inconvenience during flight, and lowering the risk of snagging.

Abstract

The invention discloses a posture-adjustable sliding rail for an ejection seat and a sliding rail control mechanism of the posture-adjustable sliding rail. The posture-adjustable sliding rail comprises a steel cable assembly, a box body, an unlocking mechanism and a holding rod. The sleeving structure of the holding rod and the unlocking mechanism is installed in the box body, and an unlocking key of the unlocking mechanism is located on the outer side of the box body, so that the holding rod is unlocked by operating the unlocking key, and the holding rod slides out along the guide rod under the action of the long spring and pops out of the box body; the small ball end of the steel cable assembly is installed in the box body, and a stop pin assembly in the steel cable assembly is fixedly installed on the sliding rail upper support. A stop pin in the stop pin assembly can penetrate through a through hole in the sliding rail upper support and is inserted into limiting holes in different positions of the arc-shaped sliding rail, and the stop pin is used for limiting the relative sliding position of the arc-shaped sliding rail and the sliding rail upper support so as to achieve the purpose of controlling the angle of the sliding rail longitudinal beam. According to the posture-adjustable sliding rail, the problems that an existing posture-adjustable sliding rail of the ejection seat is unlocked by drawing a quick-release pin, the required operation force is large, and the operation comfort is poor are solved.
