Device for improving hip joint extension assisting efficiency of flexible exoskeleton robot

Abstract

The invention discloses a device for improving the hip joint extension assisting efficiency of a flexible exoskeleton robot. The device comprises a base, the cam-like pressing rod mechanisms, a rotating block, a telescopic rod outer sleeve, a telescopic rod inner rod, a telescopic rod limiting screw, a telescopic rod locking sleeve and a Bowden cable guide pipe. One end of the rotating block is installed in the base through one cam-like pressing rod mechanism, the other end of the rotating block is connected with one end of the telescopic rod outer sleeve, and the other end of the telescopic rod outer sleeve sleeves one end of the telescopic rod inner rod; the telescopic rod locking sleeve sleeves the joint of the telescopic rod outer sleeve and the telescopic rod inner rod, a radial through hole is formed at the tail end of the other end of the telescopic rod inner rod, and the Bowden cable guide pipe is mounted in the radial through hole through a positioning screw. According to thedevice, the angle between a Bowden cable and the thigh is increased, the power assisting efficiency is improved, and the safety is higher.

Description

technical field [0001] The invention belongs to the field of flexible exoskeleton robots, and in particular provides a device for improving the efficiency of hip joint extension assisting of flexible exoskeleton robots. Background technique [0002] With the rapid development of science and technology, there is an increasing demand for wearable exoskeleton systems for human-machine collaboration in fields such as rehabilitation medicine, military affairs, and industry, especially when soldiers march long distances or work in plateau environments. This wearable exoskeleton system provides walking assistance without hindering the soldiers' limb movements, thereby improving the operational capabilities of individual soldiers. In the above application scenarios, the characteristics of the exoskeleton system should be mainly reflected in the soft human-computer interaction force, light weight, and small inertia, especially the ability to generate enough torque on the joints to im...
