Active tilt angle compensation aircraft seat

Abstract

The invention discloses an active tilt angle compensation aircraft seat. The active tilt angle compensation aircraft seat comprises a seat back, seat armrests, a seat cushion, a middle fixed plate, alower fixed plate, a six-degree-of-freedom parallel mechanism, a gyroscope, a three-axis acceleration sensor, an adjustment motor and an Arduino controller, wherein the seat cushion and the seat backare connected through a rotating shaft; the seat armrests are mounted on the seat back; the six-degree-of-freedom parallel mechanism is installed at the bottom of the aircraft seat; the movement of the seat in six degrees of freedom in space is realized by using the characteristics of strong stability, flexibility and carrying capacity of the six-degree-of-freedom parallel mechanism to compensatefor a displacement and a tilt angle in each direction. The gyroscope and the three-axis acceleration sensor are installed to monitor the angle change of the aircraft seat in real time. After the dataare transmitted to the Arduino controller, a command is generated synchronously to control the movement of the adjustment motor, thereby achieving angle compensation for the seat in a short period oftime.

Description

technical field [0001] The invention relates to the technical field of intelligent seats, in particular to a stable aircraft seat that actively compensates for the inclination angle of an aircraft when it takes off, lands, turns or encounters airflow, in particular to an active inclination compensation aircraft seat. Background technique [0002] At present, the rise of the middle class is accompanied by a massive consumption upgrade, which puts forward higher requirements for the comfort experience of aviation. At the same time, the long journey makes passengers pay more attention to the comfort of the seat, which has become an indispensable point in the competition of high-end aviation. In a recent survey on the propensity of first-class passengers, among the 12 important first-class indicators listed, seat comfort is the most concerned. And when the aircraft takes off, turns, lands, forced to land or encounters air currents, it will make the aircraft angle deflection or ...

AI Technical Summary

Problems solved by technology

And when the aircraft takes off, turns, lands, forced to land or encounters air currents, it will make the aircraft angle deflection or the aerodynamic force or moment of the aircraft will be out of balance, and the flight speed, flight altitude or flight attitude will be deflected. Rigid connection will directly transmit this effect to passengers, causing discomfort to passengers, which not only greatly affects the ride experience of passengers, but may even cause safety problems

On the other hand, the research on improving seat comfort in various countries is mostly limited to improving the material structure of the seat, and adjusting the passive adjustment of the seat stability through the shock absorbing spring. The patent document "An Angle Adjustable Aviation Seat "(CN207759040U) relates to a kind of aircraft seat of adjusting angle, but also just can manually adjust seat back angle, and is in the state of being neglected for the research of actively compensating aircraft seat inclination angle
