I designed an exercise rehabilitation device based on a push-rod drive, which enables the user to passively stretch their legs to increase knee joint mobility. Initially, I converted the angle that the human leg needs to bend into the angle that the frame must rotate, using theoretical design. Subsequently, employing a simple linkage sketch design, I correlated and adjusted the dimensions of the telescopic and fixed components. Ultimately, through theoretical design and calculations, I selected the appropriate model of the push rod. I utilized SolidWorks software for the model drawing and Arduino programming software for the program design. The main framework was constructed from aluminum profiles, connected with 3D-printed parts. Through experimentation, it was found that the device offers stable performance, is portable, and boasts a long service life.
