Abstract

The invention discloses a bionic flexible foot type tensioning mechanism, and belongs to the technical field of bionic foot type mechanisms. The bionic flexible foot type tensioning mechanism has thecharacteristics of deformability and self-adaption, and can realize rotation and motion control in space. The mechanism is characterized by comprising an upper end rack, ball joint bearings, sleeves,pressure springs, rigid rods, an optical shaft, a cross universal joint, tension springs, bases, a supporting rod and a lower end bottom plate. The bionic flexible foot type tensioning mechanism adopts an integral tension structure, the mechanism has good stability, and compared with the traditional rigid bionic foot type mechanism, the mechanism can keep stable motion in an unstructured environment, can realize the terrain adaptation function, and has a good application prospect.

Description

technical field [0001] The patent of the invention relates to a bionic foot mechanism capable of adapting to terrain, and belongs to the technical field of bionic foot mechanisms. Background technique [0002] The traditional rigid legged robot is composed of kinematic pairs, and the combination of kinematic pairs forms the working space of the robot end effector. This kind of legged robot has the advantage of high motion precision. [0003] The traditional rigid foot mechanism is large in size, heavy in structure, poor in environmental adaptability, limited in movement in a narrow space, and has shortcomings in adapting to terrain. Contents of the invention [0004] In order to solve the above problems, the present invention establishes a bionic foot mechanism based on the characteristics of self-stability, flexibility and self-adaptation of the human foot, which has self-adaptive characteristics and realizes the function of the bionic foot mobile robot to adapt to the te...
