Abstract

The invention discloses a flexible-rope-driven upper limb exoskeleton robot. The flexible-rope-driven upper limb exoskeleton robot comprises a backpack, a back width adjusting device, a shoulder jointmechanism, an upper limb length adjusting device, an elbow joint mechanism, a forearm length adjusting device and a wrist joint mechanism. A drive control system is arranged in the backpack, the backwidth adjusting device is connected with a shell of the backpack, the shoulder joint mechanism is connected with the back width adjusting device, the upper limb length adjusting device makes the shoulder joint mechanism connected with the elbow joint mechanism, and the forearm length adjusting device makes the elbow joint connected with the wrist joint. A flexible driver is in drive combination with a rope, so that the robot is smooth in motion, concise and compact in structure, and convenient in joint; the flexible-rope-driven upper limb exoskeleton robot totally includes 4 active degrees offreedom, 2 passive degrees of freedom, and the upper limb physiological structure of the human body can be well fitted; length adjusting mechanisms are arranged at the back, the upper arms, and the forearms so that the robot can be adapted to users of different sizes, and the flexible-rope-driven upper limb exoskeleton robot has higher wearing performance. The flexible-rope-driven upper limb exoskeleton robot can be applied and popularized in the aspects of rehabilitation training, power assisting and the like.

Description

technical field [0001] The invention belongs to the field of human-assisted robots, and relates to an upper limb exoskeleton robot, in particular to a flexible rope-driven upper limb exoskeleton robot. Background technique [0002] With the acceleration of population aging, the demand for robots that help the elderly and the disabled is growing rapidly, and the upper limbs of the human body are very important in daily life and require assistance or training. Exoskeleton robots have attracted wide attention in recent years due to their advantages of effectively solving human motor dysfunction, driving users to carry out daily sports or providing some assistance to the human body. [0003] Compared with the mature upper extremity exoskeleton robot technology abroad, domestic research started late and the level is relatively backward. There are few successful commercial products. The main problems are insufficient flexibility, simplified shoulder joint structure, and poor weara...
