Abstract
Description
Technical Field
[0001] This invention relates to the field of medical rehabilitation equipment technology, and in particular to a lower limb roller skating rehabilitation training device. Background Technology
[0002] Patients with traffic accidents, work-related injuries, strokes, and traumatic brain injuries often suffer from walking dysfunction, partly due to insufficient leg muscle strength and the inability to control their legs. These patients are unable to stand independently and spend most of their time in wheelchairs, which greatly reduces their physical health and quality of life.
[0003] The recovery of walking ability in these patients is closely related to the rehabilitation of motor function in the affected lower limb. Lower limb motor rehabilitation training uses devices that can maintain and restore the patient's joint range of motion, which is beneficial for restoring the limb's main motor functions. Commercially available gait rehabilitation training devices already exist, such as the Handy1 developed by Mike Topping in the UK in 1987. Another type of rehabilitation robot that has successfully entered the market includes the MANUS rehabilitation robot developed by Exact Dynamics in the Netherlands, the NUSTEP rehabilitation device in the US, the THERA.Vital intelligent rehabilitation training robot in Germany, and the MOTINMAKER developed by WORTEC in Switzerland.
[0004] However, existing gait rehabilitation training products have the following drawbacks: (1) they cannot meet the needs of movement and gliding in specific environments and situations, thus saving time and effort for patients wearing lower limb exoskeleton robots before rehabilitation training; (2) they cannot meet the needs of patients wearing lower limb exoskeleton robots to perform rehabilitation exercises without relative sliding with the ground, and to reduce the damage to the user's legs caused by external forces, thus achieving safety and stability during rehabilitation training. Therefore, it is currently necessary to develop a lower limb exoskeleton rehabilitation training device that can move and glide before rehabilitation training and is also safer and more stable during rehabilitation training. Summary of the Invention
[0005] In view of the technical defects of existing gait rehabilitation training products, the present invention aims to provide a lower limb roller skating rehabilitation training device.
[0006] The present invention provides a lower limb roller skating rehabilitation training device, which specifically has the following functions:

By controlling and / or coordinating the roller-skating foot assembly, which includes a base frame assembly, foot plate assembly, foot motor brackets, foot motors, damping and shock-absorbing roller-skating mechanism, motor connecting flange, and controller, the base frame assembly is fixedly connected to the foot plate assembly. The four foot motor brackets are fixedly connected to the base frame assembly, and each foot motor bracket is fixedly connected to a foot motor. The damping and shock-absorbing roller-skating mechanism is fixedly connected to the foot motors via the foot motor connecting flange. The control terminals of the four foot motors are connected to the controller to achieve synchronous control of the four foot motors. The foot motors can drive the roller-skating foot assembly to move and realize the movement and gliding of the lower limb exoskeleton rehabilitation device, meeting the needs of movement and gliding in specific environments and situations, and saving time and effort for patients wearing the lower limb exoskeleton robot before rehabilitation training.
[0008] 2. By controlling and / or coordinating the movement relationships of the thigh component, calf component, and roller-skating foot component, as well as the damping and shock-absorbing roller-skating mechanism that works in conjunction with the roller-skating foot component, good anti-slip capability is maintained for patients wearing the lower limb exoskeleton robot during rehabilitation training, thus achieving stability during patient rehabilitation training.

[0040] The lower limb roller skating rehabilitation training device provided by this invention is used in conjunction with a lower limb exoskeleton rehabilitation device. The lower limb exoskeleton rehabilitation device can also be a wearable lower limb exoskeleton robot. Lower limb exoskeleton rehabilitation devices or wearable lower limb exoskeleton robots are existing mature structures, and this application will not provide a detailed description of the specific structure of the lower limb exoskeleton rehabilitation device or wearable lower limb exoskeleton robot. It should be noted that the lower limb exoskeleton rehabilitation device is mainly a device for lower limb rehabilitation training, including components such as the thigh, waist, calf, foot, power supply, and control components.
[0041] The present invention provides a lower limb roller skating rehabilitation training device, comprising a waist component, a thigh component, a calf component, a roller skating foot component, and a binding component; the waist component, thigh component, calf component, and roller skating foot component are sequentially connected, and the binding component is connected to the waist component, thigh component, and calf component respectively; the roller skating foot component includes a base frame component, a foot plate component, a foot motor bracket, a foot motor, an anti-slip and shock-absorbing roller skating mechanism, a motor connecting flange, and a controller, wherein the base frame component is fixedly connected to the foot plate component, four foot motor brackets are fixedly connected to the base frame component, each foot motor bracket is fixedly connected to a foot motor, the anti-slip and shock-absorbing roller skating mechanism is fixedly connected to the foot motor through the foot motor connecting flange, and the control terminals of the four foot motors are signal-connected to the controller to achieve synchronous control of the four foot motors. The foot motors can drive the roller skating foot component to move and realize the movement and gliding of the lower limb exoskeleton rehabilitation device. This invention introduces a roller skate-type foot component, which adopts an anti-slip and shock-absorbing roller skate mechanism to meet the needs of patients to glide and move before rehabilitation training, and also to meet the needs of patients to avoid relative sliding with the ground during rehabilitation exercises. The shock-absorbing and cushioning characteristics can also reduce the damage to the user's legs caused by external forces.
[0042] The working principle of the lower limb roller skating rehabilitation training device provided by this invention is as follows:
[0043] When a patient is preparing for lower limb rehabilitation training, firstly, by selecting the initial posture mode (wearing mode) through the control system, the body limbs are correctly positioned and the waist, thighs, calves and feet are secured with straps. After wearing, the patient selects the standing posture mode (starting mode) through the control system. After completing the standing posture, the patient selects the desired movement mode through the control system: translation and sliding mode or rehabilitation training mode.
[0044] Firstly, when the translational sliding motion mode is selected through the control system, under the control of the drive mechanisms of the thigh component, calf component, and roller skate foot component, the thigh component and calf component remain stationary, keeping the patient's body upright. The roller skate foot component moves, and the foot motor rotates, driving the double-track anti-slip and shock-absorbing roller skate mechanism to rotate. This causes the foot motor bracket to rotate relative to the double-track anti-slip and shock-absorbing roller skate mechanism, which in turn causes the base frame component to rotate relative to the double-track anti-slip and shock-absorbing roller skate mechanism, and then the roller skate foot component to rotate relative to the double-track anti-slip and shock-absorbing roller skate mechanism. This drives the lower limb rehabilitation training device to translate and slide, allowing the patient to reach the designated rehabilitation training location more quickly and effortlessly.
[0045] Secondly, when selecting the exercise mode for rehabilitation training through the control system, the roller skate foot component remains stationary under the control of the drive mechanisms of the thigh component, calf component, and roller skate foot component. Furthermore, in the thigh component, the hip joint actuator drives the thigh adjustment mechanism, calf component, and roller skate foot component to rotate back and forth. Furthermore, in the calf component, the knee joint actuator drives the calf adjustment mechanism and roller skate foot component to rotate back and forth. The movement relationship between the thigh component, calf component, and roller skate foot component changes. At the same time, the anti-slip and shock-absorbing roller skate component in the roller skate foot component has the function of anti-slip and shock absorption, so that the patient will not slide relative to the ground while performing rehabilitation exercises. The shock absorption and cushioning characteristics can also reduce the damage to the user's legs caused by external forces.
[0046] Compared with the prior art, the beneficial effects of the technical solution of the present invention are reflected in the following aspects:
[0047] Structurally, a roller skate foot component is introduced, and the anti-slip and shock-absorbing roller skate mechanism has the function of anti-slip and shock absorption, which meets the needs of patients to glide and move before rehabilitation training, and also meets the needs of patients to avoid relative sliding with the ground while performing rehabilitation exercises. The shock absorption and cushioning characteristics can also reduce the damage to the user's legs caused by external forces.
[0048] The system offers two movement modes: a gliding mode and a rehabilitation training mode. In the gliding mode, the patient's gliding movement is achieved by controlling the rotation of the foot motor. In the rehabilitation training mode, a new type of anti-slip and shock-absorbing roller skate mechanism is used to achieve rehabilitation exercises without relative slippage with the ground. The shock-absorbing and cushioning characteristics can reduce the damage to the user's legs caused by external forces. This allows patients to choose different modes for different environmental conditions, thus enabling more effective, safer, and more stable lower limb rehabilitation training, helping patients return to their families and society as soon as possible.

[0106] The working principle of the lower limb roller skating rehabilitation training device provided by this invention is as follows:
[0107] When a patient is preparing for lower limb rehabilitation training, firstly, by selecting the initial posture mode (wearing mode) through the control system, the body limbs are correctly positioned and the waist, thighs, calves and feet are secured with straps. After wearing, the patient selects the standing posture mode (starting mode) through the control system. After completing the standing posture, the patient selects the desired movement mode through the control system: translation and sliding mode or rehabilitation training mode.
[0108] First, when the translational sliding motion mode is selected through the control system, under the control of the drive mechanisms of the thigh component 2, calf component 3, and roller-skating foot component 4, the thigh component 2 and calf component 3 remain stationary, keeping the patient's body upright. The roller-skating foot component 4 moves, and the foot motor 402_2 rotates, driving the double-track anti-slip and shock-absorbing roller-skating mechanism 402_3 to rotate. This causes the foot motor bracket 402_1 to rotate relative to the double-track anti-slip and shock-absorbing roller-skating mechanism 402_3, which in turn causes the base frame component 401 to rotate relative to the double-track anti-slip and shock-absorbing roller-skating mechanism 402_3, and then the roller-skating foot component 4 to rotate relative to the double-track anti-slip and shock-absorbing roller-skating mechanism 402_3. This drives the lower limb rehabilitation training device to translate and slide, allowing the patient to reach the designated rehabilitation training location more quickly and effortlessly.
[0109] Secondly, when selecting the exercise mode for rehabilitation training through the control system, under the control of the drive mechanisms of the thigh component 2, calf component 3, and roller skate foot component 4, the roller skate foot component 4 remains stationary. Furthermore, in the thigh component 2, the hip joint actuator 201 drives the thigh adjustment mechanism 202, calf component 3, and roller skate foot component 4 to rotate back and forth. Furthermore, in the calf component 3, the knee joint actuator 301 drives the calf adjustment mechanism 302 and roller skate foot component 4 to rotate back and forth. The movement relationship between the thigh component 2, calf component 3, and roller skate foot component 4 changes. At the same time, the anti-slip and shock-absorbing roller skate component 402 in the roller skate foot component 4 has the function of anti-slip and shock absorption, so that the patient will not slide relative to the ground while performing rehabilitation exercises. The shock absorption and cushioning characteristics can also reduce the damage to the user's legs caused by external forces.
