ROBOT NECK JOINT STRUCTURE

摘要

The present invention relates to a robot neck joint structure. The robot neck joint structure comprises: an shaft rotation part (10) rotating a head part (5) corresponding to the head of a robot to the left and the right; a head support (20) supporting the head part (5) to allow the head part (5) to rotate to the left and the right; a vertical support shaft (30) vertically supporting the front region of the bottom of the head support (20) to serve as a rotation center joint; a lift rotation part (40) coupled to the rear region of the bottom of the head support (20) to pitch and yaw the head support (20); and a main support (50) supporting the bottom portions of the vertical support shaft (30) and the lift rotation part (40). By allowing the head part to have natural and complex movements such as pitching or yawing by means of the shaft rotation part rotating the head part and the vertical support shaft and of two lift rotation parts connected to the shaft rotation part, the general public feel more intimate with a robot as they become interested in a variety of expressive motions of the head part during a robot performance. Also, by supporting the bottom region of the head part in a 3-point supporting way through two lift rotation parts and a single vertical support shaft, the head part can be inserted into a human-sized neck structure because the components thereof are simple and the structure thereof is compact. Also, even when power is turned off, the head part is maintained at the right position of the head. Therefore, a product becomes more reliable and is produced at low manufacturing costs and with a minimum of product defects, and provides various and stable movements.
