Robot and its neck agencies

The present invention discloses a robotic mechanism and a neck, the neck means comprises an upper plate, a lower plate, and a universal joint located on both sides of the articulated linkage of two sections, the gimbal respectively connected to upper ends and lower plates, said link mechanism comprises a telescopic device, the telescopic means for driving said link mechanism vertically telescopic, the telescopic device towards the upper end remote from the obliquely upward direction gimbal a push rod extension is formed, away from the lower end to the universal joint extends obliquely downward direction is formed at the push rod, the push rod is connected with the upper plate, the lower push rod is connected to the lower plate. On the one hand reducing the radial dimension of the neck portion of the robot; on the other hand, since both the head and the neck mechanism further extends into the body, it is possible to use part of the head and body spaces, both ends of the link mechanism to make It can be increased as much as possible radially extending arm, thereby reducing the actual gap and the power density requirements of the entire mechanism, reducing the cost.
