Multi-shaft hydraulic knee joint

Abstract

The invention provides a multi-shaft hydraulic knee joint, and belongs to the field of bionic devices. The multi-shaft hydraulic knee joint comprises a connector, a connecting body, a first connectingrod, a second connecting rod and a brake assembly, wherein one end of the connector is provided with a protruding end, one end of the connecting body is a connecting end, the other end of the connecting body is a connecting part for connecting a shank prosthesis, one end of the first connecting rod is connected with the protruding end by means of a rotating shaft structure, the other end of the first connecting rod is connected with the connecting end of the connecting body through a rotating shaft structure, one end of the second connecting rod is rotationally connected with the connector through a rotating shaft structure, the other end of the second connecting rod is connected with the connecting body by means of a rotating shaft structure, the brake assembly is arranged between the first connecting rod and the second connecting rod, one end of the brake assembly is rotatably connected with the protruding end through a rotating shaft structure, and the other end of the brake assembly is rotatably connected with the second connecting rod through a rotating shaft structure. The provided multi-shaft hydraulic knee joint is reasonable in structural design, small in occupied space and long in service life; and the multi-axis hydraulic knee joint also has the characteristics of high motion stability and high safety.

Description

technical field [0001] The invention belongs to the field of bionic devices, and more specifically relates to a multi-axis hydraulic knee joint. Background technique [0002] In today's society, in order to help lower limb amputee patients recover basic walking functions, prosthetic limbs are usually installed at the patient's amputation position. At the same time, in order to improve the patient's walking experience, the prosthetic limb is also equipped with a multi-axis hydraulic knee joint at the same position as the normal knee joint of the human body, so that the patient In the process of walking, the function of bending the legs can be realized. [0003] For the use of knee prostheses, it is very important to prevent the knee prosthesis from bending randomly during walking, which is the key to avoiding the user's fall; moreover, the bending frequency of the knee prosthesis has a great influence on the coordination of the user's walking during walking. Sex also plays a...
