Abstract

The invention discloses a rigid-flexible coupling buffer bionic foot which comprises a coupling foot bottom, an upper-portion flexible layer, a foot top cover plate, a torsion spring and a compression spring. The meshing faces of a radial foot base plate, a bottom flexible layer and a lateral foot base plate form a rigid-flexible coupling buffer interface, and the upper-portion flexible layer, the compression spring and the torsion spring and the foot top cover plate and the coupling foot bottom form a rigid-flexible coupling buffer interface. By means of ingenious matching of a rigid split structure and flexible connection, a coupling body structure is formed through rigid-flexible-rigid organic combination, and ground impact forces in the radial direction and the lateral direction are effectively absorbed and weakened. The whole rigid-flexible coupling buffer bionic foot has the advantages of having rigid supporting and flexible absorption functions and accordingly has good buffering performance.

Description

technical field [0001] The invention relates to a quadruped robot foot, in particular to a rigid-flexible coupling cushioning bionic foot. Background technique [0002] With the advancement of science and technology, bionic walking robots have developed rapidly and are widely used in many fields of society, such as agriculture, military affairs, interstellar exploration, field expeditions, emergency rescue and disaster relief, etc. According to the number of walking feet, walking robots can be divided into one-legged, two-legged, three-legged, four-legged, six-legged, eight-legged or even more, of which even numbers account for the vast majority. Compared with other types, quadruped walking robots have strong bearing capacity, good stability, simple structure, and easy control. In addition, quadruped robots can not only walk on structured roads and complex terrains in a static walking manner, It can realize high-speed walking in a dynamic walking mode, so it has received gr...
