This corresponds to the position of the foot board 21 near the first side edge 213, where the first foot 23 contacts the ground, and the position of the foot board 21 near the second side edge 214, where the foot board 21 is suspended from the ground. When walking is needed, taking the step-off of the right foot as an example for explanation, the body of the patient inclines towards the left, the center of gravity falls on the left, the first side edge 213 and the second side edge 214 of the left foot pedal 21 are both in contact with the ground, the right foot pedal 21 is entirely suspended, and at this time, the supporting rod 31 on the right side swings forwards by pushing the armrest 34 on the right side, so that the right foot pedal 21 is driven to move forwards, and the step-off of the right foot is realized. Similarly, to step the left foot forward, the body is tilted to the right, and the center of gravity is located on the right. Due to the arrangement of the first bottom feet 23, the bottom of the pedal 21 is uneven, when the corresponding foot needs to be stepped, the corresponding pedal 21 is suspended, the pedal 21 can be tilted more flexibly, the resistance of the pedal 21 is reduced, and the operation of a patient is greatly facilitated.

In one embodiment, the bottom of the pedal 21 is provided with a plurality of the first feet 23, and the plurality of the first feet 23 are arranged at intervals along the first side edge 213. The arrangement of the first feet 23 can realize a more balanced supporting effect in the front-back direction, and prevent toppling in the front-back direction.

In one embodiment, the bottom surface of the footrest 21 is further provided with a second foot 24, the second foot 24 is close to the second side edge 214, and the height of the second foot 24 is smaller than the height of the first foot 23. In this way, the pedal 21 is contacted with the ground through the first foot 23 and the second foot 24, the contact area of the pedal 21 with the ground is small, the resistance of the pedal to the ground can be reduced, and the pedal can swing forwards conveniently. Further, by providing second foot 24 near second side edge 214, when the center of gravity of the patient is tilted toward second side edge 214, a part of second side edge 214, that is, second foot 24, comes into contact with the ground, rather than the entire second side edge 214 striking the ground, the impact can be reduced.

Alternatively, each of the two corners of the footboard 21 on the first side edge 213 is provided with one of the first feet 23, and each of the two corners of the footboard 21 on the second side edge 214 is provided with one of the second feet 24. That is, the first foot 23 and the second foot 24 are distributed substantially along the circumferential direction of the footboard 21 and are distributed at four corners of the footboard 21, so that better support in four different directions, front, rear, left, and right, can be achieved. The corner in this embodiment refers to a position where two adjacent sides intersect. In addition, more first feet 23 and second feet 24 can be arranged on the bottom of the pedal 21.

The pedal 21 comprises a support plate 211 and a support frame 212 located on the bottom surface of the support plate 211, and the first foot 23 and the second foot 24 are arranged on the support frame 212. Optionally, first foot 23 and second foot 24 are each integrally formed with support frame 212. The support bracket 212 can reinforce the strength of the support plate 211 and prevent the support plate 211 from being broken. In addition, the footrest 21 may be an integral plate, i.e. not including the support frame 212, and may also support the sole of the foot.

In an embodiment, the bottom surface of the pedal plate 21 is provided with a plurality of feet at intervals along the circumferential direction, and the feet are in contact with the ground, so that the lower plate surface of the pedal plate 21 is spaced from the ground, the contact area between the pedal plate 21 and the ground is reduced, the resistance of the pedal plate 21 on the ground is reduced, and the pedal plate 21 can swing more flexibly.

Specifically, the plurality of feet include a first foot 23 and a second foot 24, the first foot 23 is disposed near between two adjacent footboard 21, i.e., near the first side edge 213, and the second foot 24 is disposed on a side of two footboard 21 away from each other, i.e., near the second side edge 214; the height of the first foot 23 is greater than the height of the second foot 24. Of course, in other embodiments, the height of the first foot 23 and the second foot 24 may be the same.

In order to prevent the patient from falling over, in one embodiment, the second side edge 214 is provided with an extension section 216, and the extension section 216 extends away from the first side edge 213. The extension section 216 is provided to increase the width of the footboard 21 in the left-right direction, so that the support area in the left-right direction is larger, and even if the center of gravity of the patient inclines towards a certain side, the extension section 216 can ensure that the center of gravity of the patient always falls within the range of the footboard 21, thereby preventing the patient from falling.

Optionally, the second side edge 214 is provided with two extending sections 216, and the two extending sections 216 are distributed along the front and the back, so that the force is more balanced in the front and back direction.

In one embodiment, the front extension 216 extends obliquely forward, and the rear extension 216 extends obliquely rearward. Therefore, the ends of the two extending sections 216 far away from the second lateral edge 214 are staggered in the front-back direction, on one hand, two supporting points with larger distance can be arranged in the front-back direction, and whether the patient topples forwards or backwards, the gravity center of the patient can be ensured to fall between the two extending sections 216; on the other hand, the two extending sections 216 form an outward gap therebetween, and the gap is gradually enlarged, so that material can be saved.

Optionally, an included angle between two extension sections 216 is greater than or equal to 90 °, specifically, an included angle between each extension section 216 and the left-right direction is greater than or equal to 45 °, so that the support distance of the two extension sections 216 in the front-back direction is greater, and the support distance of the two pedals 21 in the left-right direction is also greater.

In one embodiment, the front edge 215 of the pedal 21 extends obliquely forward in the direction in which the first edge 213 points to the second edge 214. In this way, the first side edge 213 has a narrow support distance in the front-rear direction, which can save materials, and the first side edge 213 is positioned to support the patient in a concentrated manner by the first side edges 213 of the two foot boards 21, so that the tendency of the patient to topple down can be reduced even if the front-rear support distance is small. At the second side edge 214, the support distance in the front-back direction is wider, so that when the body of the patient is inclined, the center of gravity of the patient can be ensured not to exceed the farthest support point.

In this embodiment, the front side edge 215 of the footboard 21 constitutes one of the side edges of the front extension 216. Therefore, the extension section 216 can extend forward while extending laterally, and the width of the right and left sides and the width of the front and rear sides can be increased.

In one embodiment, the rear side of the pedal 21 has a relief notch 217, and the relief notch 217 allows a wheelchair to go in and out, so as to realize the contact between the wheelchair and the paraplegia walker, thereby facilitating the patient to move from the wheelchair to the paraplegia walker. Optionally, the abdicating notch 217 is flared to have a guiding effect.

Specifically, the relief notch 217 has a groove bottom 2171 and a first groove wall 2172, the groove bottom 2171 faces the rear side, the first groove wall 2172 is close to the second side edge 214, and an included angle between the first groove wall 2172 and the groove bottom 2171 is greater than or equal to 45 °, so that the amount of the pedals 21 is reduced while a good supporting effect is ensured, and the cost is saved.

Wherein the first slot wall 2172 constitutes one of the side edges of the rear extension 216. Therefore, the extension section 216 can extend rearward while extending laterally, and the width of the right and left sides and the width of the front and rear sides can be increased.

In one embodiment, the foot plate 21 is provided with a sole fixing member 25, and the sole fixing member 25 is detachably connected to the foot plate 21, so that the sole fixing member 25 can be conveniently detached for replacement. Specifically, the sole fixing member 25 has a blocking plate 251, and the blocking plate 251 encloses to form an annular structure, and the front side of the annular structure has a notch. The feet of the patient extend into the ring-shaped structure, so that the feet can be limited to move towards the back, the left side and the right side. The gap on the front side of the annular structure can adapt to soles with different lengths, and the soles with different lengths can be ensured to extend into the annular structure.
