  • Patent number: 12186770
    Abstract: A disinfection robot, including a top plate, a bottom plate and a swinging mechanism. The top plate is located above the bottom plate. The swinging mechanism is located between the top plate and the bottom plate, and includes a swinging arm, a hinge shaft, a swinging gear, two swinging units and a driving unit. The swinging arm is hingedly connected to the bottom plate through the hinge shaft. The two swinging units are symmetrically arranged on both sides of the swinging gear. Each of the two swinging units includes a swinging shaft, an incomplete gear and a linear driver. The driving unit is configured to simultaneously drive swinging shafts of the two swinging units to rotate in opposite directions. The disinfection robot can adjust a swing amplitude of the swinging arm according to a size of a disinfection site.
