Abstract
A waist rotation structure includes a mounting disc defining a through hole, a rotatable disc located at a first side of the mounting disc, a driving device fixed to a second side of the mounting disc that is opposite the first side, and a transmission assembly. The rotatable disc defines a first cable insertion hole. The driving device includes an output shaft. The transmission assembly includes a drive gear connected to the output shaft, and a transmission cylinder extending through the through hole. The transmission cylinder includes a body that extends through the through hole, and is rotatably connected to the mounting disc and fixedly connected to the rotatable disc, and a driven gear arranged on a lateral surface of the body and engaged with the drive gear. The body defines a wiring hole extending opposite ends thereof and aligning with the first cable insertion hole.
