[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0023] The inventor's research found that there are many deficiencies in existing home walking exercise devices. The sitting-up function is missing, and it is difficult for patients to achieve the transition training from sitting to standing; the height adjustment is inconvenient, and it cannot be flexibly adjusted according to the patient's body type, height, and rehabilitation progress, with poor applicability; the safety protection is insufficient, and patients cannot obtain effective protection in time once they fall during exercise.

[0024] Based on the above findings, the present application proposes a walking exercise device for stroke patients at home, which has a reasonable structure, complete functions, and is easy to operate. The bottom plate with front and rear wheels is used as the basic support structure. By setting up a sitting-up structure, it can assist stroke patients to smoothly transition from a sitting position to a standing position; by setting up a walking structure, patients can simulate walking movements by stepping on the foot pedals. At the same time, a leg exercise mechanism is also provided, which can adjust the height and angle to adapt to patients of different heights and exercise stages; by setting up an upper limb fixation structure, it can provide stable upper limb support for patients and can adjust the height according to the patient's height; by setting up a protective emergency braking structure, in an emergency state, the movement of the device can be quickly stopped to prevent patients from being more seriously injured, providing all-round protection for the safety of patients during the exercise process.

[0025] Embodiment 1 Referring to Figures 1 - 16 , the present application discloses a walking exercise device for stroke patients at home, including a bottom plate 1. A pair of front wheels 101 and rear wheels 102 are respectively installed on the front side and the rear side of the bottom plate 1. The diameter of the front wheels 101 is larger than that of the rear wheels 102. The larger diameter of the front wheels 101 helps to maintain stability during the movement of the device and reduce the bumpy feeling, while the smaller diameter of the rear wheels 102 enables flexible steering, which is convenient for patients to operate in the home environment. Two support columns 103 are arranged through the front wheels 101 on the bottom plate 1. The support columns 103 are hollow inside and are divided into upper and lower parts by a partition plate 104.

[0026] Next, a sitting-up structure 2 is arranged above the bottom plate 1 to help patients smoothly transition from a sitting position to a standing position. The sitting-up structure 2 includes two support rods 201 fixedly and vertically arranged on the bottom plate 1. One side support rod 201 is connected to the support column 103, and the other side support rod 201 leaves a space for people to enter the device. A seat plate 202 is rotatably arranged on the support rods 201. A rotating rod 203 is arranged between the support rods 201 and the seat plate 202. A first sliding groove 2021 is opened on the side of the seat plate 202. A first motor 204 is installed on the support rod 201. The first motor 204 is a DC reduction motor, with an output torque of 5 N·m and a rotation speed of 50 r / min. The output end of the first motor 204 is connected to one end of the rotating rod 203 through a coupling, and the other end of the rotating rod 203 is connected to the first sliding groove 2021 of the seat plate 202. When the first motor 204 is started, it drives the rotating rod 203 to rotate. Then, the rotating rod 203 slides in the first sliding groove 2021, so that the seat plate 202 is smoothly changed from a horizontal placement to a vertical placement to help patients sit up. The control switch of the first motor 204 is arranged on one side of the seat plate 202, which is convenient for patients to operate.

[0027] Next, a walking structure is provided in front of the sitting-up structure 2. The walking structure includes a footrest 3 and a leg exercise mechanism 4 for enabling the patient to walk. There are 2 footrests 3, which are made of anti-slip rubber material, and anti-slip grooves with a depth of 5 mm are provided on their surfaces to increase the friction between the patient's feet and the footrest 3. The footrest 3 is rotatably connected to the support column 103 through a rotating rod 301. One side of the rotating rod 301 close to the front wheel 101 is connected by a shaft to an electric telescopic rod 302. The electric telescopic rod 302 extends into the gap of the support bar of the front wheel 101 to drive the rotation of the front wheel 101. It should be noted that the initial state of the footrest 3 is not at the lowest position. The patient steps on the two footrests 3 with both feet and drives the footrest 3 to rotate periodically in a circular motion similar to pedaling a bicycle. During this process, the rotation of the footrest 3 drives the connected rotating rod 301 to rotate, and then drives the electric telescopic rod 302 to rotate synchronously, so that the electric telescopic rod 302 drives the front wheel 101 to rotate and drives the rear wheel 102 to rotate, thereby moving the entire device. It is worth noting that for patients with inconvenient leg movement, a drive motor can also be provided at the footrest 3 to drive the footrest 3 to move, thereby driving the patient's leg movement. In an implementable manner, a plurality of telescopic suction cups 303 are provided under the bottom plate 1. When the device does not need to be moved, the electric telescopic rod 302 is retracted and the telescopic suction cups 303 are fixedly sucked to the ground to prevent the device from moving during exercise.

[0028] Further, there are 2 leg exercise mechanisms 4, and each leg exercise mechanism 4 includes: a leg wearing component and a joint adjustment component.

[0029] Specifically, the leg wearing component includes a plurality of leg fixators 401. In this embodiment, preferably 3 are provided. The uppermost leg fixator 401 is used to fix the patient's thigh position, the lowermost leg fixator 401 is used to fix the patient's calf position, and the middle leg fixator 401 is used to fix the leg position below the patient's knee. Straps are provided on the leg fixators 401 to fix them on the patient's legs (not shown in the figure).

[0030] The joint adjustment component includes a circular shell 402. The circular shell 402 has a cavity structure, and a first gear 403 and a second gear 404 that mesh with each other are arranged inside it. Telescopic rods are connected between the leg fixator 401, the first gear 403, and the second gear 404, and are used to adjust the elongation degree of the leg fixator 401 according to the height and body type of the patient. The telescopic rods include a first telescopic rod 405 fixedly connected to the first gear 403 and a second telescopic rod 406 fixedly connected to the second gear 404. The other end of the first telescopic rod 405 penetrates through the circular shell 402 and is connected to the uppermost leg fixator 401. A second sliding groove 4021 is formed below the circular shell 402 to provide an angle adjustment range for the second telescopic rod 406. The other end of the second telescopic rod 406 passes through the second sliding groove 4021 and is connected to the lowermost leg fixator 401. The middle leg fixator 401 is fixedly connected to the circular shell 402. When the patient's leg performs a walking movement, the first gear 403 and the second gear 404 mesh and rotate with each other, driving the second telescopic rod 406 to rotate a certain angle, so as to adjust the relative angle of the leg fixator 401 to adapt to the leg movement contour of the human body.

[0031] Further, the leg exercise mechanism 4 is adjusted in the relative height with the support column 103 through a first lifting component 5. The first lifting component 5 is arranged in the part below the partition plate 104 inside the support column 103, and includes a lifting rod 501 fixedly connected to the leg exercise mechanism 4, a first turbine 502 fixedly connected to the lifting rod 501, a first worm 503 meshed with the first turbine 502, and a second motor 504 that provides rotational power. The second motor 504 is an AC reduction motor, with an output torque of 8 N·m and a rotational speed of 60 r / min. Wherein, the second motor 504 drives the first worm 503 to rotate, and then drives the first turbine 502 to rotate while moving up and down relative to the first worm 503, so that the lifting rod 501 drives the leg exercise mechanism 4 to move up and down, and is used to adjust the position of the leg exercise mechanism 4 according to the height of different patients. The control button of the first lifting component 5 is arranged on one side of the support column 103, which is convenient for the patient or caregiver to operate.

[0032] Next, an upper limb fixing structure 6 is further provided inside the support column 103. The upper limb fixing structure 6 includes: a handrail 601, which is hollow inside and runs through the middle of the support column 103. The surface of the handrail 601 is provided with an anti-slip rubber sleeve to increase the friction when the patient holds it; a guardrail 602, which is hollow inside and is rotatably connected to the middle of the handrail 601 through a hinge shaft for surrounding the patient's waist; a guard plate 603, which runs through and is vertically arranged at the middle bottom of the handrail 601. Plug rods 6032 are also arranged on both sides of the guard plate 603. The plug rods 6032 can slide freely in the guard plate 603. When the guardrail 602 rotates to the lower position, the plug rods 6032 can be inserted into the openings on the opposite side of the guardrail 602 to limit the movement of the guardrail 602 when the patient moves.

[0033] Furthermore, the relative height of the upper limb fixing mechanism with respect to the support column 103 is adjusted by a second lifting assembly 7. The second lifting assembly 7 is arranged above the partition plate 104 inside the support column 103 and includes a second turbine 701 fixedly connected to the handrail 601, a second worm 702 meshed with the second turbine 701, and a third motor 703 providing rotational power. The third motor 703 is a DC reduction motor with an output torque of 6 N·m and a rotational speed of 55 r / min. Among them, when the third motor 703 drives the second worm 702 to rotate, and then drives the second turbine 701 to rotate while moving up and down relative to the second worm 702, so that the upper limb fixing mechanism moves up and down to adjust the position of the upper limb fixing mechanism according to the heights of different patients. The control buttons of the second lifting assembly 7 are arranged on the other side of the support column 103 and are separated from the control buttons of the first lifting assembly 5 for convenient operation.

[0034] Preferably, it further includes a protection emergency braking structure. The protection emergency braking structure includes a protection assembly 8 for supporting the patient's body in an emergency state and a braking assembly 10 for realizing emergency braking, wherein the protection assembly 8 and the braking assembly 10 operate synchronously.

[0035] Specifically, refer to Figures 12 - 15 The protection assembly 8 includes a waist strap 801. The waist strap 801 is provided with a hook surface and a loop surface of a magic sticker for tying the patient's waist. An accommodation groove 6031 is arranged inside the guard plate 603. The waist strap 801 is connected above the guardrail 602 through an elastic rope 803 arranged inside the accommodation groove 6031. An airbag ring 802 is semi-openly arranged on the inner side of the guardrail 602. The elastic rope 803 cooperates with a pneumatic system 9 to inflate the airbag ring 802 to support the patient's upper limbs in an emergency state.

[0036] Furthermore, refer to Figure 14 andFigure 15 The pneumatic system 9 includes an air pump 901 connected to the handrail 601 and an air inlet channel 902 arranged on the guard plate 603 and connected to the inside of the handrail 601, wherein the air pump 901, the handrail 601, the air inlet channel 902 and the guardrail 602 form a complete air flow channel, the air pump 901 is used to inflate the inside of the handrail 601, the air inlet channel 902 includes a first air inlet channel 9021 opened in the guard plate 603 and a second air inlet channel 9022 opened in the middle of the guard plate 603, the first air inlet channel 9021 is connected to the handrail 601, the second air inlet channel 9022 is connected to the guardrail 602, and the first air inlet channel 9021 and the second air inlet channel 9022 are in an inverted "T" shape, the accommodating groove 6031 is connected to the intersection of the "T" shape, and a "cross" shape is formed inside the guard plate 603. The upper end of the elastic rope 803 is clamped at the intersection of the first air inlet channel 9021 and the second air inlet channel 9022. A spring 804 is sleeved on the elastic rope 803. The second air inlet channel 9022 is connected to the airbag ring 802 through an air pipe penetrating the inside of the guardrail 602.

[0037] In the initial state, the air pump 901 fills the handrail 601 and the first air inlet channel 9021 with gas, and the elastic rope 803 is clamped at the intersection of the first air inlet channel 9021 and the second air inlet channel 9022 to block the outlet. When the patient falls, the waist strap 801 tied tightly around the waist will pull down the elastic rope 803, and pull the elastic rope 803 down to the lower part of the intersection. The air flow channel opens, and the gas in the handrail 601 and the gas inside the first air inlet channel 9021 enter the airbag ring 802 on the inner side of the guardrail 602 through the air flow channel. The airbag ring 802 inflates and drags the patient to prevent falling.

[0038] For further reference, Figures 12 - 14 The braking system 10 includes a brake rod 1001, which is arranged inside the support column 103 and connected to the handrail 601. The lower section of the brake rod 1001 matches the front wheel 101. A pressure sensor is arranged inside the handrail 601. When the pressure inside the handrail 601 is sensed to be reduced, the third motor 703 drives the handrail 601 to descend so that the brake rod 1001 is stuck to the front wheel 101, so that the entire device stops moving. At the same time, the air pump 901 starts to inflate the handrail 601 until the airbag ring 802 is full.

[0039] Working principle: When a patient with limited mobility wants to do walking rehabilitation exercises, the whole device is pushed to the bedside, the seat board 202 is placed on the bed, and after the patient sits on the seat board 202, the first motor 204 is started to help the patient smoothly transition from a sitting position to a standing position, the handrail 601 is held with both hands, the guardrail 602 is rotated to surround the patient's waist, the patient steps on the foot pedal 3 and adjusts the height of the leg exercise mechanism 4 and the upper limb fixing structure 6 according to the patient's height and body shape, and the leg exercise mechanism 4 is fixed to the patient's leg with a strap. Then, the patient starts to perform circular pedaling on the foot pedal 3 in a manner similar to pedaling a bicycle. When walking, the rotating rod 301 drives the electric telescopic rod 302 to rotate synchronously, and the electric telescopic rod 302 drives the front wheel 101 to rotate, thereby driving the rear wheel 102 to rotate, so that the whole device moves, simulating a real walking scene, and performing leg exercises. If the patient accidentally falls during the exercise, the waist strap 801 tied tightly around the waist will pull down the elastic rope 803, pull the elastic rope 803 to the lower part of the intersection of the first air inlet channel 9021 and the second air inlet channel 9022, and open the air flow channel. At this time, the gas filled into the handrail 601 by the air pump 901 and the gas inside the first air inlet channel 9021 enter the airbag ring 802 inside the guardrail 602 through the entire air flow channel, and the airbag ring 802 inflates and supports the patient's upper limbs to prevent falling. At the same time, the pressure sensor inside the handrail 601 senses the pressure reduction, and the third motor 703 drives the handrail 601 to descend, so that the brake rod 1001 is stuck to the front wheel 101, and the entire device stops moving, preventing the patient from causing secondary injuries due to the movement of the device. After the exercise, the patient can start the first motor 204 again to change the seat plate 202 from vertical to horizontal, and the patient sits down.
