Abstract
The invention discloses a stretching bionic artificial knee joint, which comprises a shank supporting rod, a thigh supporting rod, a telescopic unit, a tension spring, a slide way, a fixing block, a connecting shaft, internal threads and a knee block, wherein the shank supporting rod is fixedly connected with the shank supporting rod; wherein make the shank bracing piece remove in the slide of establishing in the thigh bracing piece through the adjustment to the telescoping unit to play the application scenario of simulation human knee, in whole design, set up the fixed block at the both ends of thigh bracing piece and shank bracing piece, with the better connection of each part. The instant center of the stretching bionic artificial knee joint designed at this time is very similar to the structure of a human body, so that the simulation effect can be better played, and the practical application of the knee joint is further promoted.
Description
Technical Field
The invention relates to the field of machinery and bionics, in particular to a stretching bionic artificial knee joint.
Background
With the development of time, the bionic application is more and more extensive, the artificial knee joint also becomes more and more important in the application of the robot, and the function of the knee joint as a very important and complex joint of a human body is self-evident. In the case of a human body, the knee ensures daily behaviors such as standing walking and bending of the human body. People are constantly developing and improving knees, and the aim of the knee protection device is to ensure that the knees can save more energy and meet various behaviors of daily life of people. Improving knee instability and energy consumption.
Disclosure of Invention
Aiming at the condition of the defects of the artificial bionic knee joint in the current market, the contact between the revolute pair sliding pairs of the stretched bionic artificial knee joint is reduced, so that the effect of saving energy is achieved, the design of the stretched bionic artificial knee joint meets various requirements of a human body on the knee as much as possible, and the requirements of the human body on the knee are simulated
The technical scheme of the invention is as follows.
Stretch-draw bionical artificial knee joint, its characterized in that includes: shank bracing piece, thigh bracing piece, flexible unit, extension spring, slide, fixed block, connecting axle, internal thread, flexible unit constitute by telescopic shaft, compression spring, flexible slide, connecting hole, be provided with the slide in the thigh bracing piece, shank bracing piece and thigh bracing piece become the X type, the shank bracing piece removes in the slide, fixed block and the both ends of shank bracing piece, the both ends of thigh bracing piece adopt the fixed connection mode, the both ends of shank bracing piece, the both ends of thigh bracing piece, the both ends of fixed block, the both ends of connecting axle all are provided with the hole, extension spring is connected with the connecting hole, extension spring is connected with the hole of connecting axle.
According to the stretching bionic artificial knee joint, the stretching bionic artificial knee joint is characterized in that: the connecting shaft is provided with internal threads so as to facilitate the connection of other components.
