Xiaopeng Motors' robot waist mechanism patent has been authorized, which allows the robot to achieve pitching or yawing motion.

Tianyancha App shows that recently, the "Waist Mechanism and Robot" patent applied by Guangzhou Xiaopeng Automobile Technology Co., Ltd. has been authorized. The summary shows that this utility model relates to the field of robot technology. It includes: a support; a first mounting shaft, including a nested first inner shaft and a first outer shaft, with the first inner shaft connected to the support; a second mounting shaft, set at a predetermined angle with the first mounting shaft, the second mounting shaft including a nested second inner shaft and a second outer shaft, with the second outer shaft connected to the first outer shaft; a drive structure, with the fixed part of the drive structure connected to the second inner shaft; a linkage structure, with the first end of the linkage structure hinged to the support, and the second end of the linkage structure hinged to the drive part of the drive structure. This utility model can enable the robot to achieve pitch or roll motion. Furthermore, the overall structure of the waist mechanism is simple, occupies a small space, and has a small weight. When the waist mechanism performs pitch or roll motion, it only needs to drive the drive structure to rotate, reducing the moment of inertia, and thereby reducing the torque demand on the linkage structure.
