Abstract
A robot joint having a dynamic sealing structure includes a power unit housing and an output shaft rotatable relative to the power unit housing. A soft and hard combined composite sealing ring is provided between the power unit housing and the output shaft. A soft first sealing ring is tightly connected with a joint to effectively seal the rotating joint. A hard second sealing ring slides relative to the joint while sealing the joint, thus reducing the obstruction to the movement of the joint. A quadruped robot applies the robot joint having the dynamic sealing structure. The two sealing rings with different hardness butt against each other to form a dynamic sealing structure used for sealing the joint and capable of maintaining the normal movement of the joint, effectively preventing rainwater, dust and the like from entering the joint, thus protecting the joint of the robot.
