Device for adjusting lifting of aero seat

Abstract

The invention relates to a device for adjusting lifting of an aero seat. The device comprises a bracket, an adjustment mechanism and slide rails, wherein the adjustment mechanism comprises a drive motor, a housing, a gear, a clutch, a screw nut and a screw rod; the drive motor is fixedly mounted on the housing; the gear and the screw nut are mounted on the housing through bearings respectively; teeth are arranged outside the screw nut; a thread is arranged on the outer diameter of the screw rod; the screw rod is mounted on the screw nut in a matched way through the thread; an output gear of the drive motor is connected with the screw nut through the clutch and the gear; the screw rod is connected with the aero seat; the slide rails are fixed to the aero seat and matched with guide rails arranged on the bracket. The device is reasonable in structure, low in space requirement and reliable in work, can be used for finishing an adjustment function of the aero seat in a small space and manually adjusting the aero seat under the circumstance that the drive motor loses power, and can be operated by an aviator to enable the aviator to enter or exit from an aircraft and guarantee that the aviator escapes from an accident.

Description

technical field [0001] The invention relates to an adjustment device, in particular to a device for adjusting the lift of an aviation seat. Background technique [0002] In the aviation field, the aircraft aviation seat adjustment device is to adapt to various flight requirements, and can adjust the seat position, that is, the height position of the seat, so that the aircraft seat can adapt to the needs of pilots of different sizes. Simultaneously, two pilots are required to sit in the cockpit on some airplanes, and when two pilots enter and exit the cockpit, due to the limitation of space, the aviation seats also need to be moved. The driving motor of the aviation seat rotates at a high speed, and it needs to be decelerated to realize the need to drive the aviation seat. At the same time, it is also required that the aviation seat cannot be locked when the driving motor is powered off, which will affect the pilot's operation and entry and exit. Aircraft, and even affect th...

Problems solved by technology

The driving motor of the aviation seat rotates at a high speed, and it needs to be decelerated to realize the need to drive the aviation seat. At the same time, it is also required that the aviation seat cannot be locked when the driving motor is powered off, which will affect the pilot's operation and entry and exit. Aircraft, even affecting the escape of pilots in accidents

Due to the small installation space and the high requirements for the adjustment device required, there is no such device at present
