  Referring to the configuration of the driving unit 200 as described above with reference to the drawings, it can be seen that the driving unit 200 according to the present invention is compactly coupled with components and is mounted in a narrow space of the human body model 100.

  Hereinafter, the operation of the human body model 100 by driving the drive unit 200 will be described with reference to FIGS. 2 and 3.

  First, when the drive motor 210 rotates forward, the rotational force of the drive motor 210 is transmitted to the screw bar 220 via the first spur gear 213 and the second spur gear 223, and the screw bar 220 starts to rotate forward. When the screw bar 220 starts to rotate forward, the elevating member 230 screwed to the screw bar 220 starts to rise along the screw bar 220.

When the elevating member 230 is raised, the relay rod 250 is also raised together, and the rising relay rod 250 pushes up the lower end of the rotating rod 240 in an arc shape. At this time, since the upper end and the lower end of the relay rod 250 are respectively connected to the coupling piece 233 of the elevating member 230 and the lower end of the rotating rod 240, the rotating rod 240 is lifted by the elevating member 230 under a high load such as torsion. Push up the bottom edge of. Further, if the elevating member 230 is raised, the link rod 260 is also raised together, and the link rod 260 that is used regularly rotates the shoulder shaft 115 forward.

  The rotating rod 240 rotates forward about the fixed shaft 271 as the lower end rises. That is, it rotates counterclockwise in the drawing and the upper part descends. When the rotating rod 240 starts to rotate forward, the upper body part 110 of the human body model 100 fixedly coupled to the upper portion of the rotating rod 240 rotates forward and bends together.

  In addition, the shoulder shaft 115 that rotates simultaneously with the forward rotation of the rotating rod 240 rotates the arm member 111 forward so that the hand of the arm member 111 approaches the umbilical portion of the human body model 100. Accordingly, as shown in FIG. 3, during the bending operation, the human body model 100 bends the upper body portion 110 and at the same time draws a hand to greet the consumer in a kind and polite posture.

  When the operation to bend the upper body part 110 of the human body model 100 is finished, the driving motor 210 rotates in the reverse direction to start the extension operation so that the upper body part 110 returns to the initial state. When the driving motor 210 rotates in the reverse direction, the screw bar 220 also rotates in the reverse direction to lower the elevating member 230. The elevating member 230 that is lowered lowers the lower end portion of the rotating rod 240 through the relay rod 250 and pulls the link rod 260 to reversely rotate the shoulder shaft 115.

  When the lower end of the rotating rod 240 is lowered, the rotating rod 240 rotates in the reverse direction about the fixed shaft 271 to lift and extend the upper body 110, and the shoulder shaft 115 that rotates in the reverse direction rotates the arm member 111 in the reverse direction. By doing so, the hand is moved away from the umbilical region of the human body model 100.

  As shown in FIG. 4, the turntable 300 senses a body 310, a rotating body 320 that is rotatably coupled to the body 310 and on which the human body model 100 is installed upright, and a human body existing in the vicinity. And a human body sensing sensor 330. When the human body sensor 330 senses a nearby consumer, the rotating body 320 rotates so that the front of the human body model 100 is directed in the direction in which the consumer is present.

  The human body sensor 330 may be implemented by a temperature sensor that detects the temperature of a human body, an ultrasonic sensor that detects the presence or absence of a surrounding object, and the like. The human body sensor 330 can detect not only a person but also things.

  After the human body model 100 is rotated so that the consumer is seen from the front, the turntable 300 transmits a signal to the driving motor 210 so that the human body model 100 bends and extends to greet the consumer. Furthermore, it can be gradually rotated to the left and right so that the shape of the clothing worn by the human body model 100 can be clearly seen by the consumer.

  The public relation robot having a compact drive unit having a specific shape and structure according to the present invention has been described with reference to the accompanying drawings. However, the present invention can be variously modified and changed by those skilled in the art. Such variations and modifications should be understood as belonging to the protection scope of the present invention.
