A rope-driven astronaut rowing training device for weightless environment

Abstract

The invention relates to a rope-driven rowing training device for astronauts used in a weightless environment. Including load control unit, paddle unit, seat unit, virtual display unit, load control unit is composed of flexible cable winding wheel, motor bracket, torque motor and guide wheel; paddle unit is composed of paddle, paddle bracket, paddle The paddle bracket is connected by a spherical hinge mechanism; the seat unit is composed of a seat, guide rails, tension springs and pedals; the virtual display unit is mainly composed of a display screen. The invention utilizes a load control unit to simulate movement resistance, transmits load force to the oar through flexible cables, and simulates the movement resistance received by the oar when paddling in water. The modular design of the rowing trainer is convenient for transportation and installation; the flexible cable is used as the transmission element, which is comfortable and safe during training; the human-computer interaction and entertainment of training are improved through the virtual display unit. The invention has simple structure, small mass and volume, and can be used for physical training of astronauts in space.

Description

technical field [0001] The invention relates to the field of aerospace life sciences, in particular to a cable-driven astronaut rowing training device used in a weightless environment. Background technique [0002] At present, my country is building a large-scale national-level space laboratory with long-term participation. At that time, Chinese astronauts will carry out space operations in the weightlessness of space, and the physical health of astronauts will determine their work efficiency in the space station. crucial factor. However, the health of astronauts in space will be tested by harsh space environments such as weightlessness, vacuum, and radiation, and the impact of weightlessness on the body is unavoidable. Studies have shown that weightlessness will cause a series of physical and psychological problems for astronauts, and even threaten the lives of astronauts in severe cases. [0003] At present, astronauts mainly combat the effects of weightlessness through p...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to address the above-mentioned defects in the prior art, to provide a rope-driven astronaut rowing trainer for a weightless environment, which solves the problem that the effect of the training equipment is not obvious under the existing space weightlessness environment, and the interaction of the trainer, Disadvantages such as poor adaptability and adjustable performance are not only suitable for astronauts in the weightless environment of space, but also for ordinary people who need rehabilitation training or normal exercise
