AI Technical Summary

Technical Problem

Traditional pneumatic exoskeleton robots have the problem of high system energy consumption. Gas drive generally adopts an open-loop power supply mode, which leads to significant energy consumption. After the actuator is actuated, the high-pressure gas is directly discharged into the atmosphere, and the gas needs to be re-inhaled from the atmosphere for compression with a high compression ratio, resulting in significant energy consumption.

Method used

It adopts a high-pressure gas internal circulation design, including an air source backpack component and an exoskeleton component, and is equipped with a high-pressure gas chamber, a buffer gas chamber and a low-pressure gas chamber. The gas is recycled through an air pump and a proportional valve to reduce energy consumption.

Benefits of technology

While retaining the advantages of flexible human-machine interaction of traditional pneumatic exoskeleton robots, the energy consumption of the pneumatic system is significantly reduced and the endurance of the pneumatic exoskeleton robot is improved.

Abstract

The invention discloses a high-pressure gas internal circulation type pneumatic exoskeleton robot, and belongs to the field of energy conservation of exoskeletons and pneumatic systems. The pneumatic exoskeleton robot comprises an air source backpack assembly and an exoskeleton assembly. The air source backpack assembly is arranged on the upper portion of the exoskeleton assembly and comprises an air source backpack and a power assembly. The air source backpack comprises a backpack body and a plurality of proportional valves, and the power assembly comprises two air pumps; air pumps are respectively arranged between the high-pressure gas cavity and the buffer gas cavity and between the buffer gas cavity and the low-pressure gas cavity in the bag body; the high-pressure gas cavity is connected with a high-pressure cavity of a hip joint cylinder and a high-pressure cavity of a knee joint cylinder of the exoskeleton assembly through gas pipes. The low-pressure gas cavity is connected with a high-pressure cavity and a low-pressure cavity of a hip joint cylinder of the exoskeleton assembly and a high-pressure cavity and a low-pressure cavity of a knee joint cylinder of the exoskeleton assembly through gas pipes, and proportional valves are connected between the gas pipes and the high-pressure gas cavity and between the gas pipes and the low-pressure gas cavity. The energy consumption of a pneumatic system can be reduced, and the overall cruising ability is improved.
