Multi-functional home service robot

A multi-functional home service robot, comprising an intelligent control system, a mechanical structure and a remote control terminal;

• the intelligent control system is mounted in the mechanical structure, and the intelligent control system is controlled by the remote control terminal, to cause the mechanical structure to act correspondingly;
• and
• the mechanical structure comprises a head, a body, a chassis, a chassis suspension protection and movement mechanism and two movable moving-wing mechanisms, the head being mounted at an upper end of the body, and the body being mounted on the chassis;
• the two moving-wing mechanisms being symmetrically mounted on two sides of the body, and the chassis suspension protection and movement mechanism being mounted on the bottom of the chassis;
• wherein the head is connected to the body by a head rotating mechanism, the head rotating mechanism comprising a body fixing plate, a central sleeve, a bearing, a head turntable, a fixed seat, a compression spring, a gland nut, a fixed frame, a head DC motor, a driving wheel, a driven wheel and at least three universal balls;
• the body fixing plate, having a middle portion sleeved outside a lower portion of the central sleeve, is horizontally mounted at the upper end of the body and connected to the central sleeve by the bearing;
• the head turntable, the fixed seat, the compression spring and the gland nut are successively sleeved on the central sleeve above the body fixing plate from the bottom up;
• the head turntable is fixedly connected to the central sleeve, the fixed seat is fixed on the head turntable, and the gland nut is mounted at an upper end of the central sleeve;
• one end of the compression spring is resisted against the fixed seat, and the other end thereof is resisted against the gland nut;
• an upper end of the fixed frame is fixed on the bottom of the body fixing plate and at a position near the central sleeve, the head DC motor is vertically fixed at a lower end of the fixed frame, and an output shaft of the head DC motor, on which the driving wheel is sleeved, is arranged in the fixed frame;
• the driven wheel is sleeved on an outer side of a lower end of the central sleeve, and the driving wheel and the driven wheel are in engaged connection;
• the universal balls are uniformly distributed on the head turntable, and the head is fixedly connected to the head turntable by the universal balls;
• and
• a power module and a motor driving module jointly control the operation of the head rotating mechanism to cause the head rotating mechanism to act correspondingly.
