Title:
ROBOT INTEGRATED JOINT UNIT AND LEGGED ROBOT APPLYING SAME
Document Type and Number:
WIPO Patent Application WO/2020/177565
Kind Code:
A1
Abstract:
A robot integrated joint unit and a legged robot applying same, related to the technical field of robot joints. An existing dual-joint circuit layout scheme affects the structural safety and aesthetic appeal of a robot, and, cables are prone to damages, thus affecting the service life of the cables. The robot integrated joint unit comprises a first electric motor and reducer assembly (3), a second electric motor assembly (4), a second reducer assembly (40), and a first output connecting rod (1). Two motors of two joints are arranged on a same side of the joints, thus preventing the need for electric motor power cables to run through the joints, effectively alleviating fatigue damage of the electric motor power cables, and extending the service life of the electric motor cables. The electric motor components and the joint connecting rod obviate the need to reserve dedicated cable through holes and a cable placement mechanism, thus allowing enhanced structural reliability; further increasing the degree of integration of a dual-joint unit, reducing the axial size of the joint unit, and enhancing structural visual appeal.
