Exoskeleton robot waist adjusting and rotating mechanism

Abstract

The invention relates to an exoskeleton robot waist adjusting and rotating mechanism, and belongs to the technical field of exoskeleton robots. A waist of a robot is connected with leg fixing rods through a rotary compensation assembly; the rotary compensation assembly includes an installation plate which is installed on the waist of the robot, the leg fixing rods are rotatably installed on the installation plate, compensation blocks are coaxially installed on the leg fixing rods, a first limiting block and a second limiting block are fixedly installed on the installation plate, the first limiting block is arranged in the clockwise rotation direction of the compensation blocks, and the first limiting block and the compensation blocks are arranged at intervals; and the second limiting blockis arranged in the counter clockwise rotation direction of the compensation blocks, and the second limiting block and the compensation blocks are arranged at intervals. The exoskeleton robot waist adjusting and rotating mechanism is provided with a compensation angle when feet swing inwards and a compensation angle when the feet swing outwards so that legs of the exoskeleton robot can swing inside and outside with the transfer of the center of gravity of a human body, the walking action is relatively flexible, and the comfort is high.

Description

technical field [0001] The invention relates to the technical field of exoskeleton robots, in particular to a waist adjustment and rotation mechanism of an exoskeleton robot. Background technique [0002] Exoskeleton robot technology is an important branch of robot technology. It involves the fields of robot technology, ergonomics, mechanics, computing science and communication technology. It is a hot research technology at home and abroad. Exoskeleton robots can help people rely on their own strength to complete more intensive tasks, such as weight-bearing, and can also help patients with rehabilitation training in medicine. The waist of an exoskeleton robot is often designed with a structure that controls the freedom of movement of the waist. This structure can limit the range of motion of the wearer through mechanical fixation. Existing exoskeleton robots are fixedly installed leg fixing plates on the waist of the robot, and the robot legs are fixedly installed on the le...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to overcome the problem that the traditional exoskeleton robot does not provide compensation for the inward and outward swing of the foot, when the user walks wearing the traditional exoskeleton robot, the walking action is relatively stiff and there is no good comfort , providing an exoskeleton robot waist adjustment and rotation mechanism
