[0032] The power unit includes a sliding rail 102 and an electric sliding block 103; one sliding rail 102 is fixedly connected to each facing side of the two bearing plates 101; a plurality of electric sliding blocks 103 are slidingly connected to each sliding rail 102; each electric sliding block 103 is fixedly connected with an adjacent connecting frame 104.

[0033] The buffer assembly includes a connecting plate 105, an elastic member 106, a pressing plate 107 and a visual buffer unit; one connecting plate 105 is connected to the upper side of each connecting frame 104; each connecting plate 105 is rotationally connected with an adjacent limiting plate 4 through a torsion spring; one embedding groove is formed in each connecting plate 105; a plurality of elastic members 106 are fixedly connected in each embedding groove of the connecting plate 105, and the elastic member 106 is a spring; the other ends of the elastic members 106 located in the same embedding groove are fixedly connected with one pressing plate 107; the visual buffer unit is connected to the rehabilitation training staircase 1.

[0034] The visual buffer unit includes a sponge pad 108 and a visual sensor 110; each pressing plate 107 is rotationally connected with an adjacent pedal 3 through a torsion spring; one sponge pad 108 is fixedly connected to the front side of each pedal 3; the visual sensor 110 is fixedly connected to the handrail 2.

[0035] The support assembly comprises a servo motor 201 and a support plate 202; each servo motor 201 is fixed to the rear side of each connecting plate 105; each support plate 202 is fixed to the output end of each servo motor 201; and the other end of each support plate 202 is in contact with the adjacent tread plate 3.

[0036] The present application changes the relative position between the tread plate 3 and the limiting plate 4 by sliding the tread plate 3 on the limiting plate 4, so that when the patient uses the rehabilitation training staircase 1 and steps on the tread plate 3 and the limiting plate 4, the distance between the tread plate 3 and the limiting plate 4 is increased or shortened, and the patient's step is matched with the tread plate 3 and the limiting plate 4, which solves the problem that the patient cannot directly step on the next tread plate 3 and limiting plate 4 when the patient's step is small, but needs to move forward a certain distance before stepping on the next tread plate 3 and limiting plate 4, resulting in the rehabilitation training staircase 1 not being convenient to use, and the specific working content is as follows:

[0037] The frontmost tread plate 3 and limiting plate 4 are described below. First, before the patient uses the rehabilitation training staircase 1, the medical staff tests the patient's step, and after the test is completed, the medical staff controls the electric sliding block 103 to slide forward or backward along the sliding rail 102 by using the remote controller, thereby driving the connecting frame 104, the connecting plate 105 and the elastic member 106 to move forward or backward, and further driving the pressing plate 107, the sponge pad 108 and the tread plate 3 to move, so that the tread plate 3 slides on the limiting plate 4, thereby adjusting the relative position between the tread plate 3 and the limiting plate 4 until the degree of matching with the patient's step, stopping the electric sliding block 103 from sliding, so that the tread plate 3 stops sliding on the limiting plate 4, and then the medical staff controls the remaining electric sliding blocks 103 to slide along the sliding rails 102 by using the remote controller, thereby driving the remaining tread plates 3 to move, and further adjusting the relative positions between the remaining tread plates 3 and the limiting plates 4 until the relative positions between all the tread plates 3 and the limiting plates 4 are adjusted, at this time, when the patient steps on the tread plate 3 and the limiting plate 4, the tread plate 3 and the limiting plate 4 bear the patient's feet, in the case that the patient's step is small, the patient cannot directly step on the tread plate 3 and the limiting plate 4, but needs to move forward a certain distance before stepping on the tread plate 3 and the limiting plate 4, resulting in the rehabilitation training staircase 1 not being convenient to use, and in the case that the patient's step is large, the patient steps on the next tread plate 3 and limiting plate 4, which makes the patient's movement too intense and is not conducive to the patient's physical recovery, compared with the prior art, the rehabilitation training staircase 1 is improved in convenience and safety.

[0038] Subsequently, during the rehabilitation training process of the patient using the rehabilitation training stairs 1, if the patient's legs cannot support the patient, causing the patient to fall forward, the patient's knees are extremely prone to collide with the front end of the tread plate 3, causing the patient's knees to be injured. At this time, the sponge pad 108 is used to initially buffer the patient's knees, and at the same time, when the visual sensor 110 on the handrail 2 monitors that the patient's body posture quickly and greatly falls forward, the visual sensor 110 transmits the signal to control the servo motor 201 on the next connecting plate 105 where the patient stands to start, and from the right to the left as the reference, the support plate 202 is driven to rotate clockwise by the servo motor 201, so that the support plate 202 is separated from the tread plate 3, so that the tread plate 3 loses the support of the support plate 202, and then when the patient's knees collide with the sponge pad 108, the impact force of the patient's knees colliding with the sponge pad 108 will be transmitted to the extrusion plate 107, as shown in Figure 5 so that the elastic member 106 is compressed, the extrusion plate 107 moves downward, and from the right to the left as the reference, the torsion spring between the extrusion plate 107 and the tread plate 3 is compressed, and the torsion spring between the limiting plate 4 and the connecting plate 105 is compressed, so that the tread plate 3 and the limiting plate 4 rotate counterclockwise, so that the impact force of the patient's knees colliding with the sponge pad 108 is absorbed by the elastic member 106, thereby achieving secondary buffering of the patient's knees by the elastic member 106, avoiding the patient's knees from being injured, causing the patient to be injured, thereby further improving the protection effect of the patient's knees.

[0039] Subsequently, the medical staff helps the patient up, and the patient's knees are separated from the sponge pad 108, so that the elastic member 106 returns to its original state, thereby moving the extrusion plate 107 upward, and the torsion spring between the extrusion plate 107 and the tread plate 3 returns to its original state, and the torsion spring between the limiting plate 4 and the connecting plate 105 returns to its original state, thereby driving the tread plate 3 and the limiting plate 4 to return to their initial states. Subsequently, according to the patient's physical condition, the patient is selectively allowed to continue training or rest.

[0040] The handrail 2 is provided with a protective sleeve made of sponge material; for absorbing the sweat on the patient's palms during training, avoiding the sweat from making the patient's hands slip on the handrail 2, causing the patient to fall down and affecting the patient's personal safety.

[0041] It also includes a sponge strip 109; each tread plate 3 has a plurality of sponge strips 109 fixed on the upper surface; when the patient steps on the tread plate 3 and the limiting plate 4, the roughness of the tread plate 3 surface is increased by the sponge strip 109, thereby increasing the friction of the tread plate 3 surface, reducing the probability of the patient slipping and falling on the tread plate 3, thereby improving the safety of rehabilitation training.

[0042] Embodiment 2

[0043] On the basis of embodiment 1, as Figure 1 and Figure 6As shown, each pedal 3 is provided with a pressure sensor.

[0044] When the patient steps on the different pedals 3 and limiting plates 4 with two feet respectively, the pressure sensor on the pedal 3 detects the pressure of the patient's two feet on the pedal 3, and then, in the process that the patient steps on the pedal 3 and the limiting plate 4 on which the front foot stands with the rear foot, the patient's rear foot is lifted and has not stepped on the next pedal 3 and limiting plate 4, so that the patient's rear foot is in a suspended state, and the patient's whole body weight is supported by the front foot, if the patient's front foot is not enough to support the whole body weight at this time, the patient's rear foot must be returned, so that the patient's rear foot is put back to the original pedal 3 and limiting plate 4, and because the patient's front foot is not stable at this time, the patient is easy to fall backward after the patient's rear foot is put back to the above position, so, when the patient's rear foot is lifted upward, the pressure sensor on the pedal 3 detects that the pressure on the pedal 3 disappears, so that the signal is transmitted to the servo motor 201 through the pressure sensor on the pedal 3, so as to start the servo motor 201 under the pedal 3 and the limiting plate 4 on which the patient's rear foot stands when the patient's rear foot is lifted, and the support plate 202 is rotated counterclockwise to the state as shown in Figure 6 from right to left, so as to make the pedal 3 and the limiting plate 4 rotate clockwise to the state as shown in Figure 6 When the patient's rear foot steps on the original pedal 3 and limiting plate 4 again (hereinafter referred to as "the original pedal 3 and limiting plate 4" as the original step), because the original step is upwardly inclined, when the patient's rear foot contacts the original step, the support of the original step to the patient's rear foot changes from the original vertical direction to the present inclined direction, so as to give the patient's rear foot a support force in the forward direction, so as to avoid the patient from falling backward and being injured, and to affect the patient's personal safety.

[0045] Embodiment 3

[0046] As shown in Figures 1-4 and Figure 7 The locking assembly includes an electric lock 301 and a fixed block 302; two electric locks 301 are fixedly connected to the rear side of each connecting frame 104; one fixed block 302 is fixedly connected to the rear side of each connecting plate 105; the lock core of each electric lock 301 cooperates with the adjacent fixed block 302; and the connection between the connecting frame 104 and the connecting plate 105 is realized through the electric lock 301 and the fixed block 302.

[0047] The following is described in the most front side of the electric sliding block 103, when the patient needs to climb the rehabilitation training, the medical staff through the remote controller makes all the electric lock 301 lock core from the fixed block 302 inside, so that the electric lock 301 and the fixed block 302 are separated from each other, and then the connecting frame 104 and the connecting plate 105 are separated from each other, and the control servo motor 201 drives the support plate 202 to rotate clockwise, so that the support plate 202 and the pedal 3 are separated from each other, and then the medical staff controls the electric sliding block 103 to slide forward along the slide rail 102 through the remote controller, so as to drive the connecting plate 105, the elastic element 106 and the extrusion plate 107 to move forward, because all the connecting frame 104 and the connecting plate 105 are separated from each other, so that the extrusion plate 107 and the pedal 3 are compressed between the torsion springs, as shown in Figure 7 , the extrusion plate 107 rotates clockwise, the pedal 3 rotates counterclockwise, so that the connection angle between the extrusion plate 107 and the pedal 3 changes from a right angle to a flat angle, and when the electric sliding block 103 continues to slide forward, the angle between all the extrusion plates 107 and the pedal 3 will change to the state as shown in Figure 7 , so that the rehabilitation training staircase 1 changes from a ladder to a slope, so as to realize the conversion of the ladder and the slope, so that the patient not only performs rehabilitation training on the ladder, but also performs rehabilitation training on the slope, increases the use adaptability of the rehabilitation training staircase 1, improves the usability of the rehabilitation training staircase 1, and improves the training effect of the patient.

[0048] In addition, after the rehabilitation training staircase 1 changes from a ladder to a slope, the moving distance of the patient on the rehabilitation training staircase 1 is marked by the sponge pad 108, so that the medical staff can directly see the climbing distance of the patient, which is beneficial to the medical staff to evaluate the rehabilitation degree of the patient.
