Problems solved by technology

The specific structures of these limb joints are different, and the range of motion is also very different (some joints have a range of motion as large as 180° in a certain state, and some joints have a motion range as small as less than 20° in a certain state). It is difficult to simulate these limb joints through a specific structure

Abstract

The invention relates to a human body joint measurement and evaluation system, which comprises a simulated person and an upper computer. The simulated person comprises a simulated trunk and simulated limbs, wherein the simulated trunk and the simulated limbs are connected together. The simulated limbs are provided with at least one simulated joint. The simulated joint comprises a first bone-like connecting piece and a second bone-like connecting piece. The first bone-like connecting piece and the second bone-like connecting piece are respectively provided with an inertia sensor. The upper computer is provided with a joint angle measuring module and a display module. The tail end of the first bone-like connecting piece is fixedly connected with a joint ball seat. The tail end of the second bone-like connecting piece is fixedly connected with a joint ball. The joint ball seat is provided with a ball socket matched with the surface of the joint ball. The joint ball seat and the joint ball are respectively made of permeable magnetic materials. A magnetic suction assembly is arranged in the joint ball seat. Under the action of the magnetic attraction force of the magnetic suction assembly, the joint ball seat is movably connected with the joint ball. The human body joint measurement and evaluation system is high in the simulation degree of simulated human joints, and is capable of automatically figuring out the angle value of each joint. Therefore, the system is suitable for the measuring and the teaching of joint angles.

Description

Technical field [0001] The invention relates to a human joint measurement and evaluation system, belonging to the technical field of bionic structures of human body models. Background technique [0002] Bionics is an interdisciplinary subject that mainly studies the structure, function and working principle of biological systems, so as to provide new design ideas and working principles for engineering technology. It involves biology, mathematics and engineering technology disciplines, and these disciplines cooperate with each other. Bridge. The continuous development of bionic technology will surely promote the development of disciplines such as mathematics and engineering, thereby bringing huge social and economic benefits to society and promoting social development. [0003] Under the people-oriented philosophy, life is regarded as the most precious treasure in the world, and the research of ergonomics is particularly necessary. When studying the relationship between human-mach...
