Abstract

The invention provides a wearable flexible upper limb exoskeleton assisting system and relates to the exoskeleton assisting system. The problems that an existing exoskeleton robot drive system is large in size, large in mass, poor in movement flexibility and poor in adaptation are solved. Two drive devices are fixed to a rigid backboard in a leftwards-rightwards-symmetrical manner. Four bowden cables serve as a transmission device, each arm controls deploying and retracting of two bowden cables through the drive device on the same side, the inner side and the outer side of each arm are each subjected to transmission control by a bowden cable, the end of the bowden cable on the inner side of each arm is fixed to a forearm inner side anchor point, and the other end penetrates through an upper arm inner side anchor point and inner side bowden cable guide pipes in sequence to be connected with the drive device on the same side; and one end of the bowden cable on the outer side of each armis fixed to a forearm outer side anchor point, and the other end penetrates through an upper arm outer side anchor point and outer side bowden cable guide pipes to be connected with the drive device on the same side. The wearable flexible upper limb exoskeleton assisting system is used for a wearable flexible upper limb exoskeleton robot.

Description

technical field [0001] The invention relates to an upper limb exoskeleton assisting system, in particular to a wearable flexible upper limb exoskeleton robot assisting system. Background technique [0002] With the continuous improvement of people's living standards and the continuous development of modern medical technology, the average life expectancy of the people has been continuously extended. After entering the 21st century, my country's aging population has gradually increased, and the society has gradually entered an aging society. Due to the decline of body functions, the elderly often suffer from functional degeneration such as lack of strength in the limbs. In today's environment where the aging population is increasing, the degeneration of the elderly's physical function should be paid attention to by the society. This will not only improve the quality of life of the elderly, but also reduce the country's pension burden. [0003] Exoskeleton robots can signific...
