Abstract: A battery pack, comprising a battery pack panel (8) and slide fasteners (1), the slide fasteners (1) each comprising an engagement tongue (2). Cavities are respectively provided on two sides of the battery back panel (8), the slide fasteners (1) are able to slide inside the cavities, and elastic elements (12) are provided between the slide fasteners (1) and the battery pack panel (8). When the elastic elements (12) exert an elastic force on the slide fasteners (1) and cause same to abut one side of the cavities, the engagement tongues (2) extend out to an outer side of the battery pack panel (8). When an external force overcomes the elastic force provided by the elastic elements (12), the slide fasteners (1) are caused to abut the other side of the cavities, and the engagement tongues (2) are completely withdrawn into the battery pack panel (8). By means of the arrangement of the structure of the slide fasteners, the battery pack is caused to be reliably fixed in and easily removed from a robot body.

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: 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: 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.

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.

Abstract: A leg structure of a quadruped robot includes a body and four separate leg modules. Each leg module includes a thigh motor assembly, a calf motor assembly, a hip joint motor assembly and an associated linkage and fixing base of the hip joint motor assembly. The hip joint motor drives the thigh and calf assembly through a parallelogram mechanism, the thigh motor assembly directly drives the thigh rod assembly, and the calf motor assembly drives the calf assembly through an anti-parallelogram mechanism. The joint motor assemblies are independent of each other and all the motor assemblies are modularized; the thigh and calf motor assemblies have a good ability to prevent external impact, and the joints on the robot body, formed by using the motor assemblies, have a large working space, thus ensuring the movement flexibility of the robot.
