Multi-Axis Ankle Rehabilitation Mechanism for Automated Training

The patent replaces the manual mechanical system of physical therapist operation with an automated mechanical rehabilitation device. The device uses motor-driven rotating mechanisms to provide passive motion exercise, substituting human physical effort with mechanical automation. This resolves the contradiction by maintaining the rehabilitation function while eliminating the time consumption and intensity limitations of manual operation.

The rehabilitation device enables self-service rehabilitation training through automated control systems. The device can operate independently without continuous manual intervention, allowing patients to receive consistent rehabilitation training at any time. This resolves the contradiction by providing both personalized attention through programmable protocols and high training efficiency through automation.

The patent implements dynamic training protocols through programmable control systems that can adjust training parameters in real-time. The device offers multiple training modes (active, passive, resistive) and can modify speed, range of motion, and resistance dynamically during exercise. This resolves the contradiction by providing both flexibility through programmable adjustments and adequate training intensity through sustained automated operation.

The rehabilitation device utilizes parameter changes in motor control to achieve varied training intensities and durations. By programmatically adjusting speed, torque, and exercise duration parameters, the device can deliver customized high-intensity training regimens that would be difficult to maintain manually. This resolves the contradiction by enabling flexible parameter adjustment while ensuring adequate training time and intensity.

The patent segments the complex multi-freedom movement mechanism into three independent rotating mechanisms (X-axis, Y-axis, Z-axis), each responsible for specific ankle joint movements. This modular segmentation allows comprehensive rehabilitation coverage while managing complexity through functional decomposition. Each mechanism can be controlled independently, simplifying the overall control architecture despite the multi-degree-of-freedom capability.

The patent implements a universal rotating mechanism design where a single integrated platform can perform multiple rehabilitation functions through coordinated rotation of three mechanisms. The same mechanical structure supports active exercise, passive exercise, and resistive exercise modes, eliminating the need for separate mechanisms for each function. This resolves the contradiction by achieving comprehensive rehabilitation capability through a unified multi-functional platform rather than multiple specialized mechanisms.
