Abstract: The present application discloses an overload impact-resistant planetary reducer, including a tooth face portion made of a rigid material and a buffer portion capable of being elastically deformed. The buffer portion is made of a material having certain rigidity and capable of being elastically deformed under an impact force, and is coaxially nested with the tooth face portion to form a reducer component capable of preventing overload impact. The planetary reducer is capable of being elastically deformed under the impact force, effectively absorbing energy during overload impact, thus protecting transmission parts such as gears. The structure is simple and practical. The present application further discloses an overload impact-resistant planetary reducer, a robot joint and a quadruped robot.

Abstract: A robot integrated joint unit and a legged robot applying same are related to the technical field of robot joints. The robot integrated joint unit comprises a first electric motor and reducer assembly, a second electric motor assembly, a second reducer assembly, and a first output connecting rod. Two motors of two joints are disposed 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.

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.

Abstract: The present application discloses a highly integrated high-performance robot joint unit, belonging to the technical field of robot apparatuses. When a reducer of an existing robot joint is in overload working state, it causes joint parts such as a reducer gear to be damaged, and a meshing tooth surface of each tooth of the reducer is unevenly worn. In the present application, when a torque transmitted to a gear ring by an output end of a motor rotor or a reducer assembly is greater than a friction torque between the gear ring and a motor base, the gear ring of the reducer assembly is driven by the output end of the motor rotor or the reducer assembly to overcome the friction torque generated under the action of a friction force generator, such that the gear ring and the motor base rotate relatively, thus realizing the frictional sliding between the reducer assembly and the motor base, limiting the torque borne by the reducer assembly, and preventing the reducer from being damaged due to the large torque from the motor end or the output end of the joint unit.

Abstract: The present application relates to the technical field of robot joints, and discloses a robot dual joint unit, and a legged robot and a cooperative manipulator using the same. The robot dual joint unit includes a first joint consisting of a first motor and reducer assembly, a second joint consisting of a second motor assembly and a second reducer; a first output connecting rod is fixedly provided on an output shaft of the first motor and reducer assembly, the second reducer is provided in the first output connecting rod, and the second motor assembly drives the second reducer through a transmission rod. In the present application, a fixed end of the second motor assembly is fixed with a fixed end of the first motor and reducer assembly, rather than a fixed end of a second motor of a conventional robot joint series structure is fixed on an output end of a first motor and reducer assembly, such that the output inertia of two output shafts of the robot dual joint is smaller, and a power cable leading to the second motor assembly of the second joint is omitted.
