Problems solved by technology

[0002] The traditional bionic foot mechanism is made of rigid connecting rods, which has poor flexibility
At the same time, the size of the mechanism is relatively large, the structure is complex, the cost is high, and there are deficiencies in buffering and shock absorption, which can easily cause mechanical damage to the mechanism in a dangerous environment and make the robot lose its ability to move.

Abstract

The invention belongs to the technical field of mechanical equipment, and particularly relates to a bionic foot mechanism with buffering and damping characteristics. The bionic foot mechanism is characterized by comprising a connecting piece, a tension spring, a fixed rod, a spherical joint bearing, a shaft, a linear bearing, a sleeve and a pressure spring. Based on the characteristic of elastic deformation of an integral tension structure, the design method of the bionic foot mechanism is provided, and the bionic foot mechanism has the characteristics of simple structure, relatively small size and low cost, and can realize the functions of buffering and shock absorption. The bionic foot mechanism can be applied to a robot walking device to reduce the impact force on the ground.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a bionic foot mechanism with cushioning and shock-absorbing properties. Background technique [0002] The traditional bionic foot mechanism is made of rigid connecting rods, which has poor flexibility. At the same time, the size of the mechanism is relatively large, the structure is complex, the cost is high, and there are deficiencies in buffering and shock absorption, which may easily cause mechanical damage to the mechanism in a dangerous environment and cause the robot to lose its ability to move. Contents of the invention [0003] In order to solve the above problems, the present invention is based on the multi-degree-of-freedom and continuous-deformation capabilities of the tensioning mechanism. By changing the shape and size of its own structure within a certain range, it has good cushioning and shock absorption characteristics, and the structure...
