Abstract

This utility model relates to a gravity-assisted knee joint rehabilitation exercise device, including a base plate. A first leg support plate and a second leg support plate are movably connected to the top of the base plate, and the first and second leg support plates are rotatably connected via a rotating shaft. This utility model provides patients with a safe, comfortable, and personalized rehabilitation exercise program through electric adjustment, gas spring assistance, and a precise angle control system. A bidirectional lead screw and electric push rod driven by a micro-motor enable precise adjustment of the leg support plate angle, while the gas spring provides necessary shock absorption and auxiliary power. The device is designed with patient comfort and ease of operation in mind, supporting various rehabilitation exercise methods, such as knee flexion and extension, and lower leg weight-bearing exercises. Its wide applicability and ease of monitoring make it an ideal choice for knee joint rehabilitation exercises.
