An ostrich-like high-speed stability joint

Abstract

The invention discloses an ostrich-stimulated high-speed stability joint. The joint is composed of a first rigid rod piece, a rear side upper end boss, an outer side upper end boss, an outer side cross flexible element, a rear side parallel flexible element, an outer side joint buffer pad, an inner hexagon screw, an outer side lower end boss, a rear side lower end boss, a second rigid rod piece, afront side lower end boss, an inner side lower end boss, an inner side cross flexible element, a double-spring buffering seat, an inner side inter-joint buffering pad, a buffering sliding block, a front side parallel flexible element, a head screw, an inner side upper end boss and a front side upper end boss. According to the ostrich-stimulated high-speed stability joint, engineering bionic operation is carried out on the special joint morphology, a soft tissue structure as well as a ratchet-similar wheel, a triangular sesamoid bone and other limiting features of an ostrich inter-tarsal-bonejoint, the bionic joint which can be applied to high-speed motion and has internal and external rotation, buffering, antagonism and other limiting features is designed; and a connection movement pairof the joint is a spherical pair, so that various loads caused by different ground environments can be borne without causing abrasion of the surface of the joint.

Description

technical field [0001] The invention belongs to the field of robots and engineering bionics, and in particular relates to an ostrich-like high-speed stability joint. Background technique [0002] Most of the existing mechanical joints are articulated structures, with only one degree of freedom of sagittal plane rotation. When the robot faces a complex external environment, it will cause all-directional loads on the joints, which will cause different degrees of wear on the joints. In addition, most of the hinged structures are rigidly connected. When the joint moves at high speed, rigid impact will occur. At the same time, when the moment of inertia is large, the problem of excessive extension will also occur. [0003] Ostriches are the fastest running bipeds in the world, with a sprint speed exceeding 70km / h. They live in deserts and wastelands all year round. The intertarsal joint of the ostrich is located in the middle of the leg, without muscle wrapping, and only fascia,...
