[0024] Shoe-shaped foot support 9 is located in the front of calf support 7, a plurality of fastening rods 10 are tightly installed on the rear of first support sliding seat 1, shoe-shaped foot support 9 is located in the front of calf support 7 by being axially connected and installed on the left side of connecting rod 6, and a plurality of fastening rods 10 are tightly installed on the rear of first support sliding seat 1, the purpose that ankle part is laid out pertinently and the stability of overall device is strengthened is achieved, shoe-shaped foot support 9 and calf support 7 can be cooperatively matched and accurately act on ankle and surrounding area to improve the rehabilitation training effect, and the effect that subsequent components are stably connected by fastening rod 10 to ensure the stable operation of leg rehabilitation training device.

[0025] A second support slide 11 is fastened to the rear of the fastening rod 10. The second support slide 11 has a second slide groove 12 with a semi-circular arc travel trajectory. By fastening several fastening rods 10 to the rear of the first support slide 1 and connecting them to the second support slide 11, and by opening the second slide groove 12 with a semi-circular arc travel trajectory on the second support slide 11, the purpose of constructing a stable structure with a specific motion trajectory is achieved. This realizes the use of the semi-circular arc trajectory of the second slide groove 12 to provide a limited motion path for the relevant connecting components, ensuring the accuracy, standardization, and adaptability of leg rehabilitation training movements to different training angle requirements.

[0026] A thigh support 13 is axially connected to the left side of the second support slide 11.

Relying on the constraint of the slide groove, it can move accurately on the prescribed trajectory, thereby driving the thigh support 13 to flexibly change position and angle during leg rehabilitation training to meet the needs of knee and hip joint rehabilitation training, without the need for additional fixation methods.

[0028] A first support block 15 is securely mounted directly beneath the first support slide 1, and a second support block 16 is mounted directly beneath the first support block 15. An angle-adjustable support wheel 17 is movably mounted in front of the first support block 15. This design aims to create a support system that can flexibly adapt to various usage scenarios, allowing the leg rehabilitation trainer to quickly adjust to a suitable support state according to different usage needs (e.g., lying in bed or sitting in a chair). Regardless of the common usage environment, the trainer can flexibly change the position and angle relationship between the various support components using the angle-adjustable support wheel 17, thereby maintaining stable support and ensuring that leg rehabilitation training can be carried out smoothly and accurately.

[0029] Angle-adjustable support wheels 17 are securely connected to the second support block 16. Several support plates 18 are axially connected and installed at both ends of the second support block 16. By securely connecting the angle-adjustable support wheels 17 to the second support block 16 and axially connecting the support plates 18 at both ends of the second support block 16, a flexible and stable support structure is constructed. This allows for convenient adjustment of the posture of the first support block 15 using the angle-adjustable support wheels 17, combined with the support plates 18 to enhance stability, ensuring reliable support for leg rehabilitation training during use. Furthermore, when not in use, the support plates 18 can be easily folded away, effectively saving space and making the entire leg rehabilitation trainer easier to store. This ensures that it meets the needs well in both use and storage states.

[0030] The specific working principle is as follows: A first groove 2 is created on the first support slide 1, and a limiting rod 3 and a first slider 4 are installed. A first motor 5, a connecting rod 6, and a calf support 7 are connected sequentially. A second motor 8 and a shoe-like foot support 9 are installed at the head of the connecting rod 6. This achieves tight coordination between the components and targeted design for the ankle. Precise control of the calf support 7's movement is achieved. Simultaneously, the second motor 8 drives the shoe-like foot support 9 to work in conjunction with the calf support 7, effectively assisting in supporting and guiding the ankle and surrounding area's movements, improving the targeted and flexible effects of ankle rehabilitation training. A semi-circular second groove 12 is created between the first and second support slides 11 using a fastening rod 10, and a thigh support 13, a slider, a first support block 15, a second support block 16, an angle-adjustable support wheel 17, and a support plate 18 are installed. This achieves the goal of constructing a stable and flexible support structure adaptable to various scenarios. It ensures the accuracy and standardization of rehabilitation training movements for all joints of the leg, adapts to different angle requirements, and provides stable support and convenient storage in different states.
