[0002] With the development of modern medical technology, rehabilitation treatment for hemiplegic patients has made some progress. However, there are still many challenges in the actual treatment process. Due to the loss or weakening of function on one side of the body, hemiplegic patients usually suffer from severe motor impairment, especially when walking. Due to abnormalities in muscle strength, coordination and gait, it is difficult for patients to restore normal gait and walking function. In order to help these patients restore limb motor function, rehabilitation training has become one of the important treatment methods.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1 —5, an adjustable lower limb rehabilitation gait trainer, including an instrument frame 100, a walking machine component 200, an upper limb fixation component 300, a lower limb training component 400, and a control and adjustment device 500. First, the bottom of the instrument frame 100 is provided with a walking machine component. The walking machine component 200 includes rollers 201, belts 202, covers 203, and a support platform 204. That is, two sets of covers 203 are fixedly connected to the bottom of the instrument frame 100. A set of rollers 201 is rotatably connected to each end of the two sets of covers 203. A belt 202 is provided between the two sets of rollers 201. A support platform 204 is provided between the two sets of rollers 201. The top surface of the support platform 204 abuts against the belt 202.
[0026] Furthermore, an upper limb fixation component 300 is fixedly connected to the top of the instrument frame. The upper limb fixation component 300 is mainly used to fix the patient's upper limb. Specifically, the upper limb fixation component 300 includes a backrest 301, a lumbar fixation belt 302, and an arm support frame 303. That is, a backrest 301 is fixedly connected to the top of the instrument frame 100, an arm support frame 303 is fixedly connected to the backrest 301, and a lumbar fixation belt 302 is fixedly connected to the backrest 301 at the bottom of the arm support frame 303. In this way, the patient's waist can be fixed by the lumbar fixation belt 302, and the patient's arm can be supported by the arm support frame 303, thereby achieving fixation of the patient's upper limb.
[0027] Furthermore, the lower limb training component 400 is provided at the bottom of the upper limb fixation component 300. The lower limb training component 400 is mainly used to train the patient's lower limbs. Specifically, the lower limb training component 400 includes a thigh coordinating frame 401, a calf coordinating frame 402, and a foot coordinating frame 403. That is, two sets of thigh coordinating frames 401 are rotatably connected to the bottom of the backrest 301. The bottom of each set of thigh coordinating frames 401 is rotatably connected to a calf coordinating frame 402. The bottom of each set of calf coordinating frames 402 is rotatably connected to a foot coordinating frame 403. The foot coordinating frame 403 abuts against the belt 202 of the walking machine component 200.
[0028] Furthermore, each thigh coordinating frame 401 on the upper limb fixation component 300 is fixedly connected to a drive motor A404, which is powered by the thigh coordinating frame 401. Each thigh coordinating frame 401 is fixedly connected to a drive motor B405, which is powered by the lower leg coordinating frame 402. Each lower leg coordinating frame 402 is fixedly connected to a drive motor C406, which is powered by the foot coordinating frame 403. More specifically, a turntable A407 is fixedly connected to the bottom of the backrest 301, and a shaft A408 is fixedly connected to the top of the thigh coordinating frame 401. The shaft A408 is rotatably connected to the turntable A407, and the drive motor A404 is powered by the shaft A408.
[0029] A turntable B409 is fixedly connected to the top of the lower leg coordinating frame 402. A shaft B410 is fixedly connected to the turntable B409. The shaft B410 is rotatably connected to the bottom of the thigh coordinating frame 401. The drive motor B405 is poweredly connected to the shaft B410.
[0030] A turntable C411 is fixedly connected to the top of the foot coordination frame 403. A shaft C412 is fixedly connected to the turntable C411. The shaft C412 is rotatably connected to the bottom of the lower leg coordination frame 402. The drive motor C406 is poweredly connected to the shaft C412.
[0031] Secondly, the aforementioned thigh coordinating frame 401, calf coordinating frame 402, and foot coordinating frame 403 are all fixedly connected with fixing straps 413. In this way, the patient's lower limbs can be fixed to the thigh coordinating frame 401, calf coordinating frame 402, and foot coordinating frame 403 through the fixing straps 413. When the thigh coordinating frame 401, calf coordinating frame 402, and foot coordinating frame 403 are driven by the drive motors A404, B405, and C406, the patient's thigh, calf, and foot can be moved synchronously. Moreover, the foot coordinating frame 403 can move on the belt 202 of the walking machine component 200. This can replicate the thrust and steps in the gait process, thereby effectively helping the patient practice and restore the movement pattern when walking normally.
[0032] Further optimized, the thigh support frame 401 is provided with a thigh receiving groove 414, the calf support frame 402 is provided with a calf receiving groove 415, and the foot support frame 403 is provided with a foot placement groove 416. In this way, the patient's thigh can be placed in the thigh receiving groove 414, the calf can be placed in the calf receiving groove 415, and the foot is located in the foot placement groove 416. This structure can effectively fix the patient's lower limbs (thigh, calf, and foot) on the support frame, preventing the patient from shifting or becoming unstable during exercise. It can also more accurately simulate the movement trajectory and gait of natural walking, helping the patient to restore a normal walking pattern and achieve a rehabilitation effect.
[0033] Finally, a control and adjustment device 500 is fixedly connected to the instrument frame 100. The control and adjustment device 500 includes a control main unit, a touch screen control module, a microcontroller, and a motor controller. The control main unit is fixedly connected to the instrument frame 100. The microcontroller and the motor controller are fixedly connected inside the control main unit. The motor controller is electrically connected to drive motors A404, B405, and C406. The touch screen control module is electrically connected to the microcontroller. Through the control program built into the microcontroller, the motor controller can work together to control drive motors A404, B405, and C406, thereby realizing the training movements before this training.
[0034] The touchscreen control module can also send signals to the microcontroller, which then processes the signals and sends them to the motor controller. The motor controller uses the signals to control the rotation speed and angle of drive motors A404, B405, and C406, thereby adjusting different walking speeds and walking strides.
