Dynamic elbow joint prosthesis and dynamic upper limb prosthesis

Abstract

The invention discloses a dynamic elbow joint prosthesis, and a dynamic upper limb prosthesis containing the dynamic elbow joint prosthesis. The dynamic elbow joint prosthesis comprises a main body structure, an upper arm (3) and a front arm (5), wherein the main body structure is a U-shaped component (9); the upper arm (3) and the front arm (5) are respectively and movably connected with a bottom plate or a side plate of the U-shaped component (9) to form a rotating pair; a hard boss (15) is arranged inside the side plate of the U-shaped component (9) for limiting; and a flexible baffling block (22) is adhered outside the hard boss (15) for buffering the vibration. An angular displacement sensor is arranged through sensor supports (33 and 34), thus achieving the real-time measurement on the angular displacement of joints. The dynamic upper limb prosthesis disclosed by the invention can achieve the movement with six degrees of freedom; and the joint damping can be adjusted; the posture of the limb can be maintained; and the movement angle can be measured in real time.

Description

technical field

[0001] The invention belongs to the field of bionic structure design. It can be used in the upper limb structure design of robots, aviation ejection or automobile safety collision dummy, and can also be used as a reference for designing upper limb rehabilitation training equipment. Background technique

[0002] In the study of aviation ejection or automobile safety collision, dynamic simulation dummy is needed for experiments. The dummy structure system not only needs to realize the motion requirements and geometric shape requirements of the limbs, but also as a dynamic simulation dummy, the inertia parameters of the limbs must also conform to the characteristics of the human body. At the same time, the structural strength can meet the requirements of the mechanical load under the experimental conditions. Compared with the traditional static dummy, the geometry requirements are easy to meet. However, the motion, inertia parameters and structural strength r...
