[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0025] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0026] Example 1

[0027] This embodiment mainly describes a device for assisting ankle training, as detailed below:

[0028] like Figures 1 to 5As shown, the device for assisting ankle training includes two foot pedals 1 and two auxiliary frames 2. The two foot pedals 1 are arranged along the length of the foot, providing a large support area for the sole of the foot to improve training comfort. Both sides of the foot pedals 1 have vertically extending flanges 11, and a foot strap 12 for securing the foot to the foot pedal 1 is provided between the two flanges 11 of each foot pedal 1. A connecting block 3 is fixedly mounted on one flange 11 of each foot pedal 1, and the two auxiliary frames 2 are rotatably mounted on the connecting block 3 via connecting shafts 4. Both connecting blocks 3 are provided with guide arc-shaped slots 31, which are used to limit the rotation angle of the auxiliary frame 2 within a specified range to achieve the purpose of precision training. Both auxiliary frames 2 are provided with guide posts 5 that extend into and slide along the guide arc-shaped slots 31. A limiting cap 6 is provided on the outside of the guide post 5 to prevent it from slipping out. The guide post 5 is a bolt, and the limiting cap 6 is a nut. The auxiliary frame 2 is provided with a screw hole for the nut to pass through. The bolt passes through the guide arc-shaped slot 31 and the screw hole on the auxiliary frame 2 in sequence and is fixed by the nut. The nut and bolt cap are located on both sides of the guide arc-shaped slot 31, allowing the bolt to slide stably within the guide arc-shaped slot 31 without slipping out. Leg straps 7 are provided on both auxiliary frames 2 for fixing the patient's legs. With this structure, when patients perform ankle training, the foot strap 12 can fix the foot to the foot pedal 1, ensuring the stability of the foot during training and preventing the training effect from being affected by foot slippage. The auxiliary frame 2 is rotatably connected to the connecting block 3 via the connecting shaft 4, and the guide post 5 can slide within the guide arc-shaped slot 31, allowing the auxiliary frame 2 to perform precise training on the patient's ankle according to the preset movement angle, thereby improving the patient's ankle rehabilitation effect. At the same time, the setting of the limiting cap 6 effectively prevents the guide post 5 from slipping out of the guide arc-shaped slot 31, ensuring the safety and stability of the training process. The design of the leg strap 7 and the auxiliary frame 2 allows patients with muscle weakness or leg weakness to fix their legs on the support, providing support and fixation for the legs, enabling patients to perform ankle movements more stably during training and enhancing the training effect. Preferably, the center of the guide arc-shaped slot 31 coincides with the axis of the connecting shaft 4. This design allows the guide post 5 to slide more smoothly within the guide arc-shaped slot 31, and the rotation of the auxiliary frame 2 to be more stable. When the patient performs ankle training, the auxiliary frame 2 can accurately rotate and adjust its position according to the ankle's movement angle, ensuring the continuity and accuracy of the training process. At the same time, the coincidence of the guide arc-shaped slot 31 and the axis of the connecting shaft 4 also helps to improve the structural strength and stability of the entire device, extending its service life.

[0029] During installation, the two auxiliary brackets 2 are first rotated onto the connecting block 3 via the connecting shaft 4. Then, the guide post 5 is inserted into the guide arc-shaped slot 31. Finally, the limiting cap 6 is installed on the outside of the guide post 5 to limit its position. The installation only requires three steps, which is simple and saves a lot of installation time and cost, improves installation efficiency, and has fewer accessories compared to the prior art, greatly reducing the risk of losing parts.

[0030] Specifically, the auxiliary frame 2 includes a calf support plate 21 and a soft elastic pad 22. The soft elastic pad is a sponge pad or a rubber pad, preferably a sponge pad. The soft elastic pad 22 is circular and is fixed to the calf support plate 21 by screws. The lower end of the calf support plate 21 is rotatably connected to the connecting block via a connecting shaft 4. There is at least one leg strap 7. The design of the calf support plate and the soft elastic pad allows the auxiliary frame 2 to better conform to the shape of the patient's leg. The calf support plate 21 is used to support the patient's leg, and the soft elastic pad 22 is used to distribute body pressure, reduce local compression, relieve pain and discomfort, and improve the patient's comfort and safety during training. The leg strap 71 enhances the fixation effect of the leg, allowing the patient's leg to remain stable during ankle training, avoiding the impact of leg swaying on the ankle training effect, and helping the patient to focus more on ankle rehabilitation training.

[0031] Specifically, two auxiliary supports 2 are respectively mounted on the outer flanges 11 of the two foot pedals 1. This layout allows the auxiliary supports 2 to better support the patient's legs, providing a stable support environment for ankle training. During training, the auxiliary supports 2 are located on the outer side of the foot pedals 1, which can effectively prevent the patient's legs from tilting inward, thereby ensuring a more accurate movement trajectory of the ankle during training and improving the training effect.

[0032] like Figure 3As shown, two connecting blocks 3 are detachably connected to the corresponding flanges 11 of the two foot pedals 1 by screws. Specifically, each flange 11 on both sides of the foot pedal 1 is provided with a connecting hole 111 and a shaft hole 112. The connecting block 3 is provided with a fixing hole 32 that mates with the connecting hole 111 and a through hole 33 that mates with the shaft hole 112. The connecting block 3 is detachably fixed to one of the flanges 11 of the foot pedal 1 by bolts passing through the fixing hole 32 and the connecting hole 111 in sequence and with the help of nuts. Through the cooperation of the connecting hole 111, the fixing hole 32, the shaft hole 112 and the through hole 33, as well as the tightening effect of the bolts and nuts, a stable connection between the connecting block 3 and the foot pedal 1 is achieved. This connection method not only ensures the firmness of the connection, but also facilitates quick assembly and disassembly operations for the user. By providing connection holes 111 and shaft holes 112 on both sides of the foot pedal 1, users can install the auxiliary frame 2 on the left or right side of the foot pedal 1 according to their own training needs and usage scenarios during actual use, which improves the ease of use and flexibility of the device.

[0033] In this fixing method, the auxiliary frame 2 is located between the flange 11 and the connecting block 3 on its side, and is rotatably connected to the flange 11 and the connecting block 3 on its side via the connecting shaft 4. Specifically, the lower end of the calf guard plate 21 of the auxiliary frame 2 has a mounting hole 23, and the connecting shaft 4 is located in the mounting hole 23. The calf guard plate 21 of the auxiliary frame 2 is rotatably connected to the connecting block 3 and the foot pedal 1 through the two ends of the connecting shaft 4 passing through the through hole 33 and the shaft hole 112 respectively. The foot strap 12 is located at the front position of the flange 11, and the connecting block 3 is fixed to the outer wall at the rear position of the flange 11. The guide arc-shaped strip hole 31 is located on the side away from the foot strap 12. This detachable connection method makes the connection between the connecting block 3 and the foot pedal 1 more flexible, making it convenient for users to assemble and disassemble the device as needed. When training is required, users can quickly install the connecting block 3 on the foot pedal 1 and connect the auxiliary frame 2; when not in use, the device can be easily disassembled for easy carrying and storage. Meanwhile, this design also facilitates maintenance and component replacement, reducing operating costs. The auxiliary frame 2 is located between the flange 11 and the connecting block 3, and is rotatably connected via the connecting shaft 4, ensuring the stability and flexibility of the auxiliary frame 2. The foot strap 12 is located at the front of the flange 11, better securing the front of the foot and ensuring stable placement of the foot on the foot pedal 1. The connecting block 3 is located at the rear of the flange 11, making the connection position of the auxiliary frame 2 more rational and providing better support for the patient's leg. The guide arc-shaped slot 31 is located on the side away from the foot strap 12, avoiding interference with it, ensuring normal movement of the auxiliary frame 2 and stable fixation of the foot strap 12, further improving the reliability and practicality of the training device.

[0034] Specifically, each foot pedal 1 has two connecting holes 111 on each side of the flange 11. The number of fixing holes 32 corresponds to the number of connecting holes 111 on each flange 11, and the fixing holes 32 are located on both sides of the connecting block 3. The fixing holes 32 are racetrack-shaped slots. Increasing the number of connecting holes 111 further improves the connection strength and stability between the connecting block 3 and the foot pedal 1. The racetrack-shaped slot design allows for a certain degree of adjustment of the bolt position within the fixing holes 32, thus better adapting to foot pedals 1 of different sizes and shapes, improving the versatility and compatibility of the device. In practical applications, this design effectively reduces connection problems caused by component size errors, ensuring stable and reliable operation of the device, while also providing users with greater adjustment space to meet the needs of different users.

[0035] Specifically, both foot pedals 1 have vertically extending heel guards 13 on their outer rear edges, and mounting blocks 14 are provided on both sides of the bottom of each foot pedal 1. The foot pedals 1 are connected to the rehabilitation training cart 8 via the mounting blocks 14. The heel guards 13 effectively prevent the patient's heel from slipping off the foot pedals 1 during training, further improving the safety and stability of the training. The mounting blocks 14 allow the foot pedals 1 to be easily connected to the rehabilitation training cart 8, integrating the ankle training device into the cart and providing patients with a more comprehensive and systematic rehabilitation training program. By combining the ankle training device with the rehabilitation training cart 8, patients can perform various rehabilitation training programs on the cart 8, simultaneously conducting ankle training, thus improving the efficiency and effectiveness of rehabilitation training. This design not only enhances the practicality of the device but also provides more convenient conditions for carrying out rehabilitation training. Each foot pedal has a threading hole on both sides of the flange. The threading hole is used to connect the auxiliary pull rope. When in use, one end of the pull rope is fixed to the threading hole, and the other end is fixed to the upper limb. When the two lower limbs drive the foot pedals to train on the rehabilitation vehicle, the two foot pedals drive the upper limbs to train at the same time.

[0036] Example 2

[0037] The structural difference between this embodiment and Embodiment 1 lies in the connection method between the connecting block 3 and the foot pedal 1:

[0038] Specifically, the connecting block 3 is integrally formed with the flange 11, and the foot strap 12 is located at the front of the flange 11, while the connecting block 3 is located at the rear of the flange 11. The guide arc-shaped slot 31 is located on the side away from the foot strap 12. The integrally formed structure of the connecting block 3 and the flange 11 improves the overall strength and stability of the device and reduces the risk of failure caused by loose connections between components. The foot strap 12, located at the front of the flange 11, can better fix the front of the foot, ensuring the stable placement of the foot on the foot pedal 1. The connecting block 3, located at the rear of the flange 11, makes the connection position of the auxiliary frame 2 more reasonable and can better support the patient's leg. The guide arc-shaped slot 31, located on the side away from the foot strap 12, avoids interference with the foot strap 12, ensuring the normal movement of the auxiliary frame 2 and the stable fixation of the foot strap 12, further improving the reliability and practicality of the training device.
