Technical Field

[0001] This utility model belongs to the technical field of rehabilitation machines, and in particular relates to a lower limb rehabilitation robot. Background Technology

[0002] Lower limb rehabilitation primarily targets patients with lower limb injuries or functional impairments, providing restorative training to improve lower limb function and enhance their quality of life. As vital support and locomotor organs, the health of the lower limbs directly impacts an individual's basic living abilities, such as walking and standing. Lower limb injuries or functional impairments can lead to mobility difficulties and a decline in quality of life. Therefore, lower limb rehabilitation plays a crucial role in restoring lower limb function and improving quality of life.

[0003] Common lower limb rehabilitation machines increase blood circulation and prevent joint stiffness by maintaining muscle contraction and relaxation and joint mobility. However, in actual use, different patients have different lower limb lengths, and fixed-configuration lower limb rehabilitation machines cannot meet the needs of different patients, and the adjustment operation is complicated and inconvenient. To address these issues, we provide a lower limb rehabilitation robot to solve the aforementioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a lower limb rehabilitation robot, which solves the problems in the background art through the specific structural design of the rehabilitation support component and the rehabilitation adjustment component.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a lower limb rehabilitation robot, including a rehabilitation support component. The rehabilitation support component includes a central air-conditioning control slide, and a plurality of adjustment and limiting holes are evenly opened on the two inner side walls of the central air-conditioning control slide. A rehabilitation adjustment component is slidably fitted on the surface of the rehabilitation support component. The rehabilitation adjustment component includes a hollow support base that is slidably fitted with the central air-conditioning control slide. A first through-hole is opened on each of the two opposite sides of the hollow support base. A horizontally movable limiting plug is slidably arranged inside the first through-hole, and the limiting plug is inserted into the adjustment and limiting hole.

[0006] The present invention is further configured such that the rehabilitation support assembly includes a fixedly installed rehabilitation support platform, the central air conditioning control slide is fixedly connected to the upper surface of the rehabilitation support platform, a rehabilitation support seat is fixedly connected to the upper surface of the rehabilitation support platform, and rehabilitation pedals are rotatably installed on both sides of the rehabilitation support seat.

[0007] The present invention is further configured such that a rehabilitation limiting seat is fixedly connected to the upper surface of the hollow support base, two limiting guide grooves are symmetrically opened at the bottom of the hollow support base, a limiting transmission block is fixedly connected inside the limiting guide groove, and an adjustment transmission plate is fixedly connected to the upper surface of the limiting transmission block; the limiting insertion post is fixedly connected to the corresponding adjustment transmission plate, an inclined adjustment groove is opened on the upper surface of the adjustment transmission plate, and two second through holes are symmetrically opened on the side of the hollow support base near the rehabilitation support base, and a limiting drive crossbar is slidably arranged inside the second through hole.

[0008] The present invention is further configured such that a transmission link is fixedly connected between the two limiting drive crossbars, the transmission link is located outside the hollow support base, a return spring is fixedly connected between the transmission link and the hollow support base, and a pressing block is fixedly connected to the side of the transmission link away from the return spring; a limiting support block is fixedly connected to the end of the limiting drive crossbar away from the transmission link, a limiting drive column is fixedly connected to the lower surface of the limiting support block, and the limiting drive column slides in cooperation with the corresponding tilt adjustment groove.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0021] Please see Figure 1-5 This utility model is a lower limb rehabilitation robot, including a rehabilitation support component 1. Specifically, the rehabilitation support component 1 includes a central air-conditioning control slide 101, and a plurality of control and limiting holes 102 are evenly opened on the two inner side walls of the central air-conditioning control slide 101. A rehabilitation adjustment component 2 is slidably fitted on the surface of the rehabilitation support component 1. The rehabilitation adjustment component 2 includes a hollow support seat 201 that is slidably fitted with the central air-conditioning control slide 101. A first through-hole is opened on each of the two opposite sides of the hollow support seat 201. A horizontally movable limiting plug 202 is slidably installed inside the first through-hole, and the limiting plug 202 is inserted into the control and limiting hole 102.

[0022] The operation process of this embodiment is as follows: After fixing the position of the rehabilitation support component 1, the rehabilitation adjustment component 2 is adjusted to move horizontally according to the length of the lower limb of the rehabilitation object and the needs of exercise, so that the distance between the rehabilitation object and the rehabilitation device meets the rehabilitation needs. The two limiting plugs 202 are controlled to move horizontally synchronously and move closer to each other, while the limiting plugs 202 move away from the corresponding control limiting hole 102. The hollow support 201 slides horizontally along the central air conditioning control slide 101 until the hollow support 201 moves to the corresponding position. Then the limiting plugs 202 are released, and the two limiting plugs 202 move horizontally synchronously and move away from each other until the limiting plugs 202 are inserted and engaged with the control limiting hole 102 at the corresponding position, thereby limiting the position of the hollow support 201. Specific Implementation Example 2

[0024] Please see Figure 1-5 Based on the specific embodiment 1, the rehabilitation support component 1 further includes a fixedly installed rehabilitation support platform 103. A centrally controlled sliding track 101 is fixedly connected to the upper surface of the rehabilitation support platform 103. A rehabilitation support seat 104 is fixedly connected to the upper surface of the rehabilitation support platform 103. Rehabilitation pedals 105 are rotatably installed on both sides of the rehabilitation support seat 104. Restraint straps are installed on the rehabilitation pedals 105. The rehabilitation subject places both feet on the corresponding rehabilitation pedals 105, and uses the restraint straps to constrain the position of the feet. The rehabilitation subject performs rehabilitation exercises by rotating the rehabilitation pedals 105 through the feet.

[0025] Furthermore, a rehabilitation limiting seat 203 is fixedly connected to the upper surface of the hollow support 201. Two limiting guide grooves 204 are symmetrically opened at the bottom of the hollow support 201. A limiting transmission block is fixedly connected inside the limiting guide groove 204. An adjustment transmission plate 205 is fixedly connected to the upper surface of the limiting transmission block. The limiting insertion post 202 is fixedly connected to the corresponding adjustment transmission plate 205. An inclined adjustment groove 206 is opened on the upper surface of the adjustment transmission plate 205. The inclined direction of the inclined adjustment groove 206 gradually tilts from one end near the hollow support 201 to the other end towards the corresponding limiting insertion post 202. Two second through holes are symmetrically opened on the side of the hollow support 201 near the rehabilitation support 104. A limiting drive crossbar 207 is slidably installed inside the second through holes.

[0026] Furthermore, a transmission link 208 is fixedly connected between the two limit drive crossbars 207. The transmission link 208 is located outside the hollow support base 201. A return spring 209 is fixedly connected between the transmission link 208 and the hollow support base 201, and a pressing block is fixedly connected to the side of the transmission link 208 away from the return spring 209. A limit support block 210 is fixedly connected to the end of the limit drive crossbar 207 away from the transmission link 208. A limit drive column is fixedly connected to the lower surface of the limit support block 210, and the limit drive column slides in cooperation with the corresponding tilt adjustment groove 206.

[0027] The operation process in this embodiment is as follows: The rehabilitation subject sits on the rehabilitation limiting seat 203. Before starting rehabilitation exercises, the position of the rehabilitation limiting seat 203 is adjusted so that the distance between the rehabilitation limiting seat 203 and the rehabilitation pedal 105 meets the needs of the rehabilitation subject's lower limb exercises. The specific operation is as follows:

[0028] Manually pushing the pressing block causes the transmission link 208 to move closer to the hollow support seat 201, compressing the return spring 209. The limit drive crossbar 207 moves synchronously with the transmission link 208. Under the connecting action of the limit drive crossbar 207, the limit support block 210 moves synchronously, and the limit drive column moves synchronously with the limit support block 210. Under the sliding cooperation between the limit drive column and the corresponding tilt adjustment slide 206, the adjustment transmission plate 205 moves synchronously under force. The two adjustment transmission plates 205 move synchronously closer to each other, thereby driving the two limit plug-in columns 202 to move synchronously closer to each other. The two limit plug-in columns 202 gradually move away until they disengage from the corresponding adjustment limit hole 102, moving the recovery limit seat 203, causing the hollow support seat 201 to slide horizontally along the interior of the central air conditioning control slide 101 until the hollow support seat 201 moves. After reaching the corresponding position (the distance between the rehabilitation limiting seat 203 and the rehabilitation pedal 105 meets the needs of the rehabilitation subject's lower limb exercise), the external force applied to the transmission linkage 208 is released. Under the elastic recovery action of the return spring 209, the limiting drive crossbar 207 moves in the opposite direction. Under the sliding cooperation between the limiting drive column and the corresponding tilt adjustment slide 206, the adjustment transmission plate 205 moves synchronously away from each other, thereby causing the two limiting plug-in columns 202 to move synchronously away from each other until the limiting plug-in column 202 is inserted into the adjustment limiting hole 102 at the corresponding position, thereby limiting the position of the rehabilitation limiting seat 203. When performing rehabilitation exercises, the rehabilitation subject sits on the rehabilitation limiting seat 203 and places both feet on the corresponding rehabilitation pedal 105. The position of the feet is restrained by the restraint straps, and the rehabilitation exercises are performed by rotating the rehabilitation pedal 105 through the feet.
