[0034] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1-5 As shown, this embodiment provides a foot support device 400 for a lower limb rehabilitation training device. The foot support device 400 includes a support plate 1, two connecting plates 2, and two adjustment components 3. Two support plates 1 are spaced apart to support the feet of the rehabilitation subject. One end of each of the two connecting plates 2 is connected to the support plate 1. The two adjustment components 3 respectively connect the other end of the connecting plates 2 to the leg support component 300 of the lower limb rehabilitation training device. The adjustment components 3 are configured to adjust the relative position of the two support plates 1 in the horizontal plane.

[0036] A support plate 1 is provided to support the feet of the training object. Two connecting plates 2 are provided to connect the two support plates 1 to the leg support component 300 of the lower limb rehabilitation training equipment. An adjustment component 3 is also provided between the connecting plate 2 and the support plate 1. The adjustment component 3 is used to adjust the relative position of the two support plates 1 on the horizontal plane so that the two support plates 1 can adapt to the feet of different training objects, improve the comfort and experience of the training object, and thus ensure the training effect of the lower limb rehabilitation training equipment.

[0037] It is worth noting that, for different training subjects, the relative positions of the two foot support devices 400 in the horizontal plane can be adjusted according to the angle between the midlines of their two feet to conform to the training subject's foot size. During training, the position of the foot support device 400 relative to the leg support 300 remains unchanged, and the relative position of the two support plates 1 in the horizontal plane is adjusted via the leg support 300. For example, this adjustment can be made via the ankle joint assembly in the leg support 300.

[0038] Specifically, the support plate 1 is foot-shaped to better support the feet of the training subject. To ensure better fit between the training subject's feet and the support plate 1, a connecting component 11 is provided on the support plate 1 to fix the support plate 1 to the feet of the rehabilitation subject. Connecting components 11 are also provided at the instep and heel positions.

[0039] For example, such as Figure 1 and Figure 2 As shown, the connecting component 11 is configured as a strap 111, making connection more convenient. In other embodiments, such as Figures 3-5As shown, the connecting component 11 may further include a connecting strap 112 and a connecting buckle 113. One end of the connecting strap 112 is provided with a female connecting end, and the other end is provided with a male connecting end along its length. One end of the female connecting end of the connecting strap 112 can pass through the connecting buckle 113 and selectively connect to the male connecting end at a suitable position according to the condition of the training object's foot. The female and male connecting ends can be selected with different connection methods. In this embodiment, Velcro is used as the female and male connecting ends, which is reusable.

[0040] Furthermore, such as Figure 1 As shown, the connecting plate 2 is positioned on the side of the two support plates 1 that are far apart from each other, so that when the training object is placed on the foot support device 400, the leg support 300 is positioned on the outside of the training object's foot, reducing interference from the leg support 300 to the training object. Preferably, the support plate 1 and the connecting plate 2 are integrally formed. Integral formation reduces the need for connecting parts and makes the connection more reliable. Of course, the support plate 1 and the connecting plate 2 can also be separate components, connected by connecting parts, as long as they can provide support for the training object's foot and connect to the leg support 300.

[0041] In this embodiment, as Figure 2 As shown, the adjustment component 3 is configured to adjust the relative angle between the two support plates 1 in the horizontal plane. It can be understood that the foot-shaped support plates 1 have a foot midline 200, and the area between the two support plates 1 is a sagittal plane 100. The adjustment component 3 adjusts the angle between the foot midline 200 and the sagittal plane 100. When the foot midline 200 is parallel to the sagittal plane 100, the two support plates 1 are parallel. When the front end of the foot midline 200 forms an angle with the sagittal plane 100, the two support plates 1 are in an "inward" shape; when the rear end of the foot midline 200 forms an angle with the sagittal plane 100, the two support plates 1 are in an "outward" shape. By adjusting the angle between the foot midline 200 and the sagittal plane 100 using the adjustment component 3, it can accommodate different training subjects. In other embodiments, the adjustment component 3 can also adjust the relative position of the two support plates 1 on a non-horizontal plane, such as adjusting the height difference between the front and back or the left and right sides of the support plates 1. Those skilled in the art can make adjustments according to the foot posture of the training object, and no specific limitations are made here.

[0042] Specifically, such as Figures 2-5As shown, the adjustment component 3 includes a first adjusting member and a second adjusting member. The first adjusting member is connected to the connecting plate 2, and the second adjusting member is connected to the leg support member 300. Rotation between the first and second adjusting members allows the connecting plate 2 and the leg support member 300 to rotate relative to each other in the horizontal plane, thereby adjusting the angle between the midline 200 of the foot and the sagittal plane 100 of the two support plates 1. It is worth noting that the first and second adjusting members can be directly rotatably connected to achieve relative rotation between the connecting plate 2 and the leg support member 300 in the horizontal plane. Alternatively, in other embodiments, the first and second adjusting members can be indirectly rotatably connected through other structures. Those skilled in the art can configure structures that allow indirect rotatable connections according to actual needs; no specific limitations are made here, as long as relative rotation between the connecting plate 2 and the leg support member 300 in the horizontal plane is achieved.

[0043] Furthermore, the foot support device 400 also includes a locking component. By setting the locking component, the positions of the first adjustment member and the second adjustment member are fixed, thereby making the two support plates 1 form a preset angle in the horizontal plane. When the trainee is training, the position of the two support plates 1 relative to the leg support member 300 is stable and reliable, ensuring the safety of the trainee using the lower limb rehabilitation training equipment.

[0044] As an alternative to the foot support device 400, one of the first and second adjusting members is a rotating shaft and the other is a rotating hole. The relative rotation of the connecting plate 2 and the leg support 300 in the horizontal plane is achieved by rotating the rotating shaft in the rotating hole.

[0045] For example, such as Figure 2 As shown, the rotating shaft is the first adjusting bolt 311, and the rotating hole is a threaded hole. The first adjusting bolt 311 is threadedly connected to the threaded hole. The angle of the connection between the first adjusting bolt 311 and the threaded hole is used to adjust the angle of the connecting plate 2 and the leg support 300 in the horizontal plane, which is convenient for adjustment.

[0046] Correspondingly, the locking component is a locking nut. When the screw angle between the first adjusting bolt 311 and the threaded hole is adjusted to a suitable position, the locking nut can be screwed and locked with the first adjusting bolt 311 to limit further rotation of the first adjusting bolt 311 and the threaded hole, thereby ensuring the fixed position of the adjusted connecting plate 2 and the leg support 300.

[0047] As an optional solution for the foot support device 400, such as Figures 3-5As shown, the rotating shaft is a rotating shaft 321, the rotating hole is a through hole, and the locking assembly includes a first mating part disposed on the rotating shaft 321 and a second mating part that mates with the first mating part. Through the mating of the second mating part and the first mating part, the rotation angle of the rotating shaft 321 in the through hole is fixed, thereby fixing the position of the connecting plate 2 and the leg support 300.

[0048] For example, such as Figure 3 The first mating component is a positioning pin 322, and the second mating component is a plurality of positioning holes 21. The plurality of positioning holes 21 are disposed on the periphery of the rotating shaft 321. The positioning pin 322 is disposed on the rotating shaft 321 through a mounting lug 324. The diameter of the positioning hole 21 matches the outer diameter of the positioning pin 322. The adjustment process of the positioning pin 322 and the positioning hole 21 is as follows: the positioning pin 322 disengages from the positioning hole 21, driving the rotating shaft 321 to rotate within the through hole and rotate to a suitable position. Then, the positioning pin 322 is placed in the positioning hole 21 corresponding to that position to fix the relative angle between the connecting plate 2 and the leg support 300 in the horizontal plane.

[0049] Furthermore, the locking assembly also includes an elastic element 323. One end of the elastic element 323 abuts against the mounting ear 324, and the other end abuts against one end of the positioning pin 322. When the positioning pin 322 disengages from the positioning hole 21, the elastic element 323 is compressed. When it is necessary to place the positioning pin 322 into the positioning hole 21, the elastic element 323 can drive the positioning pin 322 into the positioning hole 21, making adjustment more convenient.

[0050] In another embodiment, such as Figure 4 As shown, the first mating component includes a second adjusting bolt 333, and the second mating component consists of a sliding groove 331 and a slider 332. The slider 332 can slide within the sliding groove 331. The second adjusting bolt 333 is threadedly connected to the slider 332, and the second adjusting bolt 333 is mounted on one side of the rotating shaft 321 via a mounting lug 324. The adjustment process using the second adjusting bolt 333, the sliding groove 331, and the slider 332 is as follows: Tighten the second adjusting bolt 333 to allow the slider 332 to slide within the sliding groove 331, driving the rotating shaft 321 to rotate within the through hole, thereby causing the connecting plate 2 and the leg support 300 to rotate relative to each other in the horizontal plane. When rotated to a suitable position, the slider 332 is fixed at a certain position within the sliding groove 331 to fix the relative angle between the connecting plate 2 and the leg support 300 in the horizontal plane.

[0051] In yet another embodiment, as Figure 5As shown, the first mating part is a third adjusting bolt 341 set on the radial side of the rotating shaft 321 via a mounting ear 324, and the second mating part is an abutment end 22. The third adjusting bolt 341 is threadedly connected to the abutment end 22 and one of the rotating shaft 321. The adjustment process using the third adjusting bolt 341 and the abutment end 22 is as follows: Tighten the third adjusting bolt 341 so that the rotation rotates within the through hole, so that the connecting plate 2 and the leg support 300 rotate relative to each other in the horizontal plane. When the rotation reaches a suitable position, the rotation angle of the rotating shaft 321 relative to the fixed end is fixed, so as to fix the relative angle between the connecting plate 2 and the leg support 300 in the horizontal plane.

[0052] For example, the relative angle between the adjustable connecting plate 2 and the leg support 300 in the horizontal plane using the above adjustment method can be -20° to 90°, depending on the comfort of the training object, and no specific limitation is made here.

[0053] This embodiment also discloses a lower limb rehabilitation training device, including the foot support device 400 as described in any of the above embodiments. The lower limb rehabilitation training device using the aforementioned foot support device 400 can adapt to different training subjects, allowing for adaptive adjustments based on foot posture, thus improving the comfort and versatility of the lower limb rehabilitation training device while ensuring better training results.
