Pressure self-adaptive gradient change anti-load garment

Abstract

The invention discloses a pressure self-adaptive gradient change anti-load garment which comprises an abdominal bag, a thigh bag, a shank bag, an acceleration induction reversing unit and a controller, the abdominal bag can be communicated with external pressurized gas, a first pressure proportional valve is arranged between the abdominal bag and the external pressurized gas, and the abdominal bag, the thigh bag and the shank bag are sequentially communicated. A second pressure proportional valve is arranged between the belly bag and the thigh bag, a third pressure proportional valve is arranged between the thigh bag and the shank bag, the shank bag is connected with an air outlet, and the air outlet can be communicated with external pressurized air. According to the pressure self-adaptivegradient change anti-load garment, the acceleration sensor is used for sensing the property and magnitude of acceleration, and the flow and direction of air pressure input are controlled according tothe acceleration, so that on one hand, a user does not need to bear high-level pressure during low overload, and the endurance time of the body to overload is prolonged; on the other hand, corresponding pressurizing directions can be automatically selected according to different overload directions, and the tolerance of the human body to overload is improved.

Description

technical field [0001] The invention relates to the technical field of aviation protective equipment and its surrounding supporting facilities, in particular to an anti-G suit with pressure adaptive gradient change. Background technique [0002] During aerospace flight, flight personnel will encounter a variety of special mechanical environments, and the loads acting on the human body in this environment have a great impact on the safety of the occupants. In order to ensure the health and safety of the occupants during the flight, the development of protective equipment is particularly important. [0003] When the spacecraft is launched, landed, or turns at variable speeds, it will generate a large acceleration, which will lead to uneven distribution of blood in the pilot's body. For example, when the plane accelerates to ascend, the blood will transfer to the lower limbs, resulting in insufficient oxygen supply to the pilot's brain, which may seriously cause black vision, ...

AI Technical Summary

Problems solved by technology

[0007] However, there are still problems in the above-mentioned prior art: (1) the pressure ratio is a fixed value, which is not high enough for pilots of different sizes; (2) the internal pressure of the airbag of the lower limbs is still the internal pressure of the side tube; Protection of occupants with acceleration in different directions
