Problems solved by technology

[0004] Most of the knee joints on the existing prosthetics adjust the pace by adjusting the damping of liquid or gas. However, the adjusted pace is at the same pace when walking, and the human body needs to adapt to the pace of the prosthesis. When you want to change the speed, you need to manually adjust it in real time, which is extremely difficult

Embodiment

[0037] An intelligent bionic knee joint, referring to Figure 1 to Figure 5 As shown, the intelligent bionic knee joint is used to connect between the thigh prosthesis and the calf prosthesis, which includes a connecting piece 1 fixedly connected to the thigh prosthesis, and a knee joint simulation device 3 fixedly arranged under the connecting piece 1 for simulating the human prosthesis , an air pressure damping device working in cooperation with the knee joint simulation device 3, a detection device for detecting the current moving state, and an air pressure damping device for adjusting the air pressure damping in response to the detection device, so as to realize real-time adjustment of the knee joint according to the walking speed of the human body The effect of exercise state.

[0038] specific reference image 3 As shown, the connector 1 is a square cone connector 1 to make the connection with the thigh prosthesis more stable, and the knee joint simulation device 3 is a...

Abstract

An intelligent bionic knee joint is used for being connected between an above-knee prosthesis and a below-knee prosthesis and comprises a connector, a knee joint simulation device, a first air pressure damping device, a detection device and a second air pressure damping device. The connector is fixedly connected with the above-knee prosthesis, the knee joint simulation device is fixedly arranged below the connector and used for simulating a human prosthesis, the first air pressure damping device cooperates with the knee joint simulation device in operation, the detection device is used for detecting a current moving state, and the second air pressure damping device responds to the detection device to adjust air pressure damping. Therefore, real-time adjustment of knee joint movement statesaccording to human walking speeds can be realized.

Description

technical field [0001] The invention relates to a bionic device, in particular to an intelligent bionic knee joint. Background technique [0002] In today's society, due to various reasons, one of the basic functions of human beings has been lost - groups that cannot walk upright are happening all the time, which undoubtedly brings great inconvenience to their lives. However, the advent of artificial legs (prosthetics) has solved their pain spiritually. With the development of science and technology, the structure and function of artificial legs have also been further improved. But this is always a concept of mechanical devices, and most of them are follow-up products, which lack the unique functions of human muscles. The walking of human legs is the result of the joint motion of active force-inertial force-damping force , which is not available in modern artificial leg mechanisms. [0003] The knee joint is the largest joint in the human body with the most complex struct...
