[0002] The neck joint mechanism plays a very important role in the design of the robot. The neck joint in the prior art is too rigid, that is, the two parts that move relative to each other have a common center of rotation. This kind of neck joint is obviously not suitable for the structure of flexible robots. middle

Abstract

The invention discloses a flexible neck joint mechanism capable of flexing and extending to back and front and having a nodding function and belongs to the field of flexible robots. The flexible neckjoint mechanism comprises connector A, connector B and a flexible neck joint body; the flexible neck joint body includes a lifting rod magnetically attracted to the connector A, a telescopic joint core fixedly connected to the lower end of the lifting rod, and a telescopic joint housing fixed to the connector B; the telescopic joint core is a uniform-section round tube 45 degrees arced in a curveform and is mounted in the telescopic joint housing; the telescopic joint core and the telescopic joint housing can freely slide with no relative rotation. The flexible neck joint mechanism is a two-DOF (degree of freedom) flexible neck joint mechanism applicable to flexible robots, can nod by extending the neck, and has no fixed center when swinging to left and right.

Description

technical field [0001] The invention mainly relates to the field of flexible robots, in particular to a flexible neck joint mechanism capable of flexion and extension forward and backward with a nodding function. Background technique [0002] The neck joint mechanism plays a very important role in the design of the robot. The neck joint in the prior art is too rigid, that is, the two parts that move relative to each other have a common center of rotation. This kind of neck joint is obviously not suitable for the structure of flexible robots. middle. Therefore, designing a flexible neck joint with two degrees of freedom of motion has universal application value. Contents of the invention [0003] The technical problem to be solved in the present invention is: aiming at the technical problems existing in the prior art, the present invention provides a dual-degree-of-freedom robot that can be used in flexible robots, can realize the nodding function by extending the neck, an...
