Problems solved by technology

[0002] Most of the existing bionic joints are controlled by metal hinges and various complex screws and pins. Due to the use of more complex mechanical structures, the requirements for size and appearance are strict, and it is difficult to apply to joints with human body and size changes. Mechanism, there is no real imitation of human bone shape, which lim

Abstract

The invention relates to a joint device in the fields of robots and artificial joints. The device is a bionic joint device with closed lubrication, which has an added lubrication function, is capable of bending and twisting in multiple directions and can be controlled for limiting; and the device with changed shape and size can be used for various part joints of a human body or other animals. In an elastically telescopic joint shell, lubricant grease corresponding to a wear-resistant material is filled, and a driving joint and a driven joint are matched by bending, twisting and sliding in various directions in a protection cavity and controlled by the limit connection of a high-strength unstretchable strong material, which is arranged on the cavity as required to limit the motion direction and the bending degree and have the effects of anti-separation and safety protection. The bending direction of the joints can be changed by changing the contact surface shapes of the joints. An anti-shock flexible material can favorably buffer various kinds of impact, take a buffer effect, protect the joints and lessen impact on other organs. Along with the development of the material science, the bionic joint device can be also used as a human-body joint substitute in the field of medical man-made bionic joints.

Description

technical field [0001] The invention belongs to the innovative device of the joint device in the field of robots and artificial joints, in particular, the device has increased lubrication, can bend and twist in multiple directions, and can also limit the position control, and is a bionic joint device with closed lubrication. After the shape and size of the device change, it can be used for joints of various parts of the human body or other animals. Background technique [0002] Most of the existing bionic joints are controlled by metal hinges and various complex screws and pins. Due to the use of more complex mechanical structures, the requirements for size and appearance are strict, and it is difficult to apply to joints with human body and size changes. Mechanisms do not really imitate the shape of human bones, which limits the application of mechanical joints and bionic joints of robots. In addition, all kinds of related researches on bionic joints are only trying to cha...
