Depending on the height of the person, hold the bracket B8 in one hand to fix its position, and rotate the stud 4 with the other hand. By continuously rotating the stud 4 and using its threaded connection with the bracket B8, the height of the bracket B8 can be quickly adjusted.

[0020] Preferably, one end of one of the brackets A1 is welded with an extension post 101, and one end of the extension post 101 forms a sliding fit with the inner wall of the other bracket A1; Preferably, the outer circumferential wall of the extension column 101 is welded with a plurality of protruding columns 102 at equal intervals, and the inner wall of the bracket A1, into which one end of the extension column 101 is inserted, is provided with a concave hole that matches the size of the protruding column 102. Depending on the individual's body size, the width of the two supports A1 can be adjusted. Specifically, hold the two supports A1 and pull them in opposite directions until the tops of the two supports B8 are aligned with the distance between the patient's armpits. At this point, an extension post 101 at the corresponding position is inserted into the protruding post 102, thereby limiting the width of the U-shaped base support. The adjustment is relatively convenient.

[0021] Preferably, the outer wall of the support B8 at the horizontal line is fitted with an anti-slip sleeve 9 to increase the friction when the patient grips it.

[0022] Furthermore, a support plate 7 is rotatably connected to the top of the bracket B8, and a soft pad 701 is adhered to the top surface of the support plate 7; the patient places both armpits on the support plate 7, which provides upper body support during walking.

[0023] Furthermore, the bottom surfaces of the U-shaped base are rotatably connected to two sets of rollers 17 on both sides; when the patient's armpits are supported on the support plate 7 and their hands are gripping the anti-slip sleeves 9 to walk, the rollers 17 can support the support structure, which helps the patient with walking training and avoids unnecessary burden during the patient's walking.

[0024] The support structure in this invention can be adjusted according to the actual body shape and height of different patients, making the design quite user-friendly.

[0025] Both brackets B8 are fixed to the outer walls of the horizontal line with fixing plates 10 by bolts. A wearable walking aid component is provided on one side of the fixing plate 10. The wearable walking aid component includes a thigh arm 11, a lower leg arm 3, a connecting plate 18 rotatably connected to one side of the lower leg arm 3, a strap 2 fixed to one side of the connecting plate 18 by bolts, and a strap 2 12. Among them, an extension arm 301 is slidably connected to one side inner wall of the thigh arm 11 and the lower leg arm 3, and the corresponding sides of the two extension arms 301 are rotated together by a pivot. Preferably, the second strap 12 is fixed to the outer wall of one of the extension arms 301 by bolts; Preferably, both the first strap 2 and the second strap 12 are adjustable structures, which can be achieved through buckles or the like; the design of the first strap 2 and the second strap 12 can adapt to the different thicknesses of the patient's legs and feet.

[0026] When wearing the device, the patient's legs and feet are connected to the two thigh arms 11 and the lower leg arms 3 respectively through strap 1 2 and strap 2 12. When walking, the patient can take a step forward with the assistance of the support structure to achieve active walking training.

[0027] Furthermore, the wearable walking aid component also includes a passive traction walking aid structure, which includes a motor 5 fixed to the inner wall of the bottom of the fixed plate 10 by bolts, a wire roller 6 rotatably connected to the inner wall of one side of the fixed plate 10, a traction rope 601 wound around the outer wall of the wire roller 6, an I-beam wheel 20 fixed to one side of the thigh arm 11 by bolts, a housing 19 fixed to one side of one of the extension arms 301 by bolts, a pulley rotatably connected to the inner wall of one side of the housing 19, and a T-shaped column fixed to one side of the lower leg arm 3 by bolts. One end of the I-beam wheel 20 is rotatably connected to one side of the fixed plate 10, and one end of the wire roller 6 is connected to the output end of the motor 5 through a coupling. Preferably, one end of the traction rope 601 is wrapped around the outer wall of the I-beam 20 and the pulley once in sequence and then tied to the T-shaped post; Once worn, the motor 5 can be started each time a person takes a step. According to the rules of leg flexion and extension, the motor 5 drives the winding of the thread roller 6, thereby using the traction rope 601 to pull the thigh arm 11 and the lower leg arm 3 to achieve passive walking training for the patient.

[0028] Furthermore, a control panel 16 electrically connected to the motor 5 is fixed to one side of the outer wall of the fixing plate 10 by bolts.

During patient walking training, pressure sensor array 15 and IMU 14 are used to sample each 'step', thereby monitoring the patient's walking speed, stride length, etc., so as to provide medical staff with real-time data reference on the patient's training progress. In addition, it can monitor whether there is a shift in the center of gravity, thus improving the safety of training.

[0029] Working principle: Depending on the individual's height, one hand holds the support B8 to fix its position, while the other hand rotates the stud 4. Through the continuous rotation of the stud 4 and its threaded connection with the support B8, the height of the support B8 can be quickly adjusted. Depending on the individual's build, the width of the two supports A1 can be adjusted. Specifically, hold both supports A1 and pull them in opposite directions until the tops of the two supports B8 are aligned with the distance between the patient's armpits. At this point, an extension post 101 at the corresponding position inserts into the protruding post 102, thus limiting the width of the U-shaped base. During wear, the patient's legs and feet are connected to the two thigh arms 11 and calf arms 3 via straps 1-2 and 2-12, respectively.

[0030] In use, the patient rests their armpits on the support plate 7 and holds onto the anti-slip sleeves 9 with both hands while walking. The rollers 17 provide support for the support structure, assisting the patient in walking training. Furthermore, with each step, the motor 5 can be activated, and according to the leg flexion and extension rules, the motor 5 drives the winding of the thread roller 6. This utilizes the traction rope 601 to pull on the thigh arm 11 and lower leg arm 3, achieving passive assisted walking training for the patient. Example 2: A walking assistance training device, such as Figure 1 As shown, in order to increase the functionality of the equipment, this embodiment makes the following improvements based on embodiment 1: the outer walls of the two brackets A1 are fixed with side supports 13 by bolts; Preferably, the bottom of the side support 13 has a gap of 1-3cm with the ground; The device does not impair the patient's mobility during walking. When the device tilts due to physical exhaustion or other reasons, the side supports 13 on both sides can support the ground, thereby effectively preventing the patient from falling and increasing the functionality of the device.
