The two pulley assemblies 40 are a first pulley assembly 41 and a second pulley assembly 42, and the two leg rope traction devices 20 are a first leg rope traction device 21 and a second leg rope traction device 22. The structure of the first pulley assembly 41 is the same as that of the second pulley assembly 42, and the structure of the first leg rope traction device 21 is the same as that of the second leg rope traction device 22.

[0056] Please see Figure 1 and Figure 4 As shown, in this embodiment, the pulley groups in both the first pulley assembly 41 and the second pulley assembly 42 include a first pulley 401 and a second pulley 402. The first pulley 401 and the second pulley 402 are disposed on the width-adjustable frame 30 and located on one side above it. One end of the main traction rope 403 is configured with two branch ropes, which are respectively connected to the two traction ropes 202 via the first pulley 401 and the second pulley 402, thereby connecting the leg rope traction device 20 to the pulley assembly. It should be noted that the distance between the two first pulleys 401 and the second pulley 402 can be adjusted to adapt to different occasions and users.

[0057] Please see Figure 3 , Figure 4 and Figure 6 As shown, in this embodiment, the traction rope 202 is detachably connected to the main traction rope 403 via a buckle 2022. Furthermore, it should be noted that the end of the traction rope 202 connected to the main traction rope 403 is bent into a loop structure via a rope clip 2023. This loop structure is hooked within the buckle 2022, allowing the rope length to be adjusted by modifying the position of the rope clip 2023 on the traction rope 202, thus accommodating users of varying heights. In other embodiments, the end of the main traction rope 403 connected to the traction rope 202 can also be bent into a loop structure via a rope clip 2023, allowing the rope length to be adjusted by modifying the position of the rope clip 2023 on the main traction rope 403.

[0058] Please see Figure 1As shown, in this embodiment, the main traction rope 403 in the first pulley assembly and the second pulley assembly is a complete rope component, and the first connector is a first pulley component 404. The first pulley components 404 in the two pulley assemblies are located at the bottom of the adjustable width frame 30 near both ends. One end of the main traction rope 403 is connected to the first leg rope traction device 21, and the other end passes through the pulley group in the first pulley assembly, the first pulley component 404, and the pulley group in the second pulley assembly in sequence to connect to the second leg rope traction device 22, so that the user's two legs can be linked together through the pulley group.

[0059] Please see Figures 3 to 5 As shown, in another embodiment, the pulley assembly further includes a second pulley component 405, which is slidably disposed on the upright 303.

One end of the traction rope 202 is connected to a branch rope on one end of the main traction rope 403, and the traction rope 202 is connected to the leg binding component to assist the user's lower limb movement.

[0064] In some other embodiments, the pulley assembly can also be directly mounted on the crossbar of the main body support 10, thereby directly mounting the leg rope traction device 20 together with the main body support 10.

[0065] Please see Figure 8As shown, in this embodiment, the leg binding component includes a thigh binding component 2031. The thigh binding component 2031 is used to bind the patient's thigh. For example, it can be fixed to the patient's thigh using Velcro or other means for easy wearing. Specifically, one end of the traction rope 202 is connected to the main traction rope 403, and the other end is connected to the thigh binding component 2031 to facilitate traction of the patient's leg. It should be noted that in this embodiment, the traction rope 202 is symmetrically arranged on both sides of the thigh binding component 2031 to avoid displacement of the thigh binding component 2031 due to uneven force on the left and right sides when the traction rope 202 is tightened, thereby preventing injury to the patient.

[0066] Please see Figure 9 As shown, in another embodiment, the leg binding component includes a thigh binding component 2031 and a calf binding component 2032. The thigh binding component 2031 and the calf binding component 2032 are used to bind the patient's thigh and calf, respectively. For example, they can be fixed to the patient's thigh and calf using Velcro or similar methods for easy wearing. Specifically, one end of the traction rope 202 is connected to the main traction rope 403, and the other end passes through the thigh binding component 2031 and is fixedly connected to the calf binding component 2032 to facilitate traction of the patient's leg. It should be noted that in this embodiment, the traction rope 202 is symmetrically arranged on both sides of the thigh binding component 2031 and the calf binding component 2032 to avoid displacement due to uneven force on the thigh binding component 2031 and the calf binding component 2032 when the traction rope 202 is tightened, thereby preventing injury to the patient.

[0067] Please see Figure 10 As shown, in another embodiment, the leg binding component includes a thigh binding component 2031, a calf binding component 2032, a thigh support component 2033, and a calf support component 2034. The structure and connection method of the thigh binding component, the calf binding component 2032, and the traction rope 202 are similar to those in the above embodiment, and will not be repeated here. In this embodiment, the thigh support component 2033 is symmetrically arranged on both sides of the thigh binding component 2031, and one end of it is fixedly connected to the thigh binding component 2031. The calf support component 2034 is symmetrically arranged on both sides of the calf binding component 2032, and one end of it is fixedly connected to the calf binding component 2032. One end of the thigh support component 2033 is rotatably connected to one end of the calf support component 2034. In use, its rotation axis is close to or coincides with the rotation axis of the knee joint.

[0068] Please see Figure 10As shown, in this embodiment, a knee joint pad 2035 is provided on the inner side of the rotatable connection between the thigh support 2033 and the calf support 2034. Its rotation axis is close to or coincides with the knee joint rotation axis. The knee joint pad 2035 acts on both sides of the knee joint to cushion and reduce discomfort caused by the support, and also facilitates binding and fixing the patient's leg. Additionally, a knee joint pad 2036 is provided on the rear side of the rotatable connection to reduce movement of the thigh binding component 2031 and the calf binding component 2032 when the leg is bent under the traction of the traction rope 202.

[0069] Please see Figure 11 As shown, in some other embodiments, a safety limiting device 202a is also provided on the traction rope 202. The safety limiting device 202a plays a limiting role when the traction rope 202 moves, which can prevent abnormal bending of the user's legs to a certain extent and provide a certain degree of leg support. It should also be noted that the position of the safety limiting device 202a can be modified according to the human body of different height groups to accommodate people of different heights.

[0070] Please see Figure 11 As shown, in another embodiment, the leg binding component includes a thigh binding component 2031, a calf binding component 2032, and a foot binding component 2037. The structure and connection method of the thigh binding component 2031, the calf binding component 2032, and the traction rope 202 are similar to those in the above embodiments, and will not be repeated here. The foot binding component 2037 is connected to the traction rope 202 via a foot traction rope 2038. Specifically, the foot binding component 2037 is connected to the traction rope 202 via the foot traction rope 2038, with one end of the foot traction rope 2038 connected to the traction rope 202 and the other end fixedly connected to the foot binding component 2037. The foot binding component 2037 can be fixed to the user's shoe using Velcro or similar methods. When the traction rope 202 is in a slack state, the foot traction rope 2038 is also in a slack state, allowing the ankle joint to move freely. When the traction rope 202 is tightened, the foot traction rope 2038 tightens along with the traction rope 202, thus fixing the ankle joint. The foot binding component 2037 allows the user's ankle joint a certain amount of room to move.

[0071] Please see Figure 12As shown, it also includes the ankle joint angle limiting device 205, which includes a foot mounting part 2051 and a lower leg mounting part 2052. The foot mounting part 2051 has an arc groove, and the lower leg mounting part 2052 has a corresponding pin. The pin and the arc groove form a sliding pair. The ankle joint angle limiting device 205 can be used in conjunction with the safety limiting device 202a or the knee joint limiting device 204. When the user's lower limb is abnormally bent, such as when the traction side leg as the supporting leg gives way, it can suppress the giving way state to a certain extent and control the user's leg at the lowest position to avoid falling.

[0072] It should be noted that the foot binding component can also be used in the leg binding components of the other embodiments described above.

[0073] This invention proposes a rehabilitation walking aid. Based on the original functions of the walking aid, the leg traction component works in conjunction with the walking aid to provide assistance to the user's lower limbs and help with lower limb movement. Through the combined use of the bilateral leg rope traction device and the walking aid, the user can achieve greater autonomy in controlling their legs and can independently adjust stride length, speed, and direction, resulting in better safety.

[0074] This invention proposes a rehabilitation walking aid that not only provides some assistance to the lower limbs, but also helps to rehabilitate some users with lower limb motor dysfunction.

[0075] This invention proposes a rehabilitation walking aid. When using a rope-driven device, the rope-driven device is controlled by collecting information on the user's plantar force and the walking aid's movement distance, thereby traction on the user's lower limbs and providing significant assistance. In addition, the structure is simple and can provide the user with a certain amount of space to move.

[0076] This invention proposes a leg rehabilitation walking aid that employs a safety limiting device and an ankle joint angle limiting device, which can provide a certain degree of protection for the user during use and avoid safety problems caused by insufficient strength in the supporting leg.

[0077] This invention proposes a rehabilitation walking aid that can also fix the ankle joint to a certain extent through the ankle joint limiting component, and also give the ankle joint a certain range of motion.
