Detailed Description
The invention is described in detail below with reference to the figures and the embodiments.
As shown in fig. 1 to 3, a wearable lower limb rehabilitation exercise training device 10 according to the present invention includes: a calf support 11, a knee adapter 12 and a thigh support plate 13. The calf support 11 is connected to the lower end of the knee adapter 12. The thigh support plate 13 is pivotally connected to the upper end of the knee adapter 12. After the patient wears the wearable lower limb rehabilitation exercise training device 10, the thigh support plate 13 rotates relative to the knee adapter 12 according to the leg movement of the patient when the patient walks, so that the patient is assisted in walking training.
As a further aspect, the wearable lower limb rehabilitation exercise training device 10 further includes: a foot pad assembly 14, an actuator 15, and a controller 16. One end of the actuator 15 is rotatably connected to the knee adapter 12 and the other end is fixedly connected to the thigh support plate 13. When mounted, one side of the thigh support plate 13 is pivotally connected to the upper end of the knee adapter 12, one end of the actuator 15 is pivotally connected to the upper end of the knee adapter 12 and the other end is fixed to the thigh support plate 13, so that the thigh support plate 13 can be rotated relative to the knee adapter 12. The foot pad assembly 14 is used to contact the sole of a user's foot to detect the stance of the plantar surface of the user's foot. The actuator 15 is used to control the rotational damping of the thigh support and the knee adapter 12, thereby adjusting the amount of rotational damping between the thigh support and the knee adapter 12 in accordance with the walking gait of the patient. For example, when the patient stands, the actuator 15 controls the rotation damping of the thigh support and the knee adapter 12 to increase, so that the thigh support and the knee adapter 12 are difficult to rotate, and the patient can stand more stably and has higher safety; when the patient walks, the angle between the lower leg and the upper leg needs to be changed, namely the leg needs to be bent, at this time, the actuator 15 controls the rotation damping of the upper leg support and the knee adapter 12 to be reduced, so that the upper leg support and the knee adapter 12 can easily rotate, and the leg of the patient can be bent freely. In this way, the rehabilitation training of the patient can be effectively assisted. The controller 16 is used for controlling the actuator 15 to adjust the rotation damping according to the detection data of the foot pad assembly 14, so that the rehabilitation training for the patient is more accurate and effective. The controller 16 is electrically connected to the actuator 15 through a wire.
Specifically, the foot pad assembly 14 includes: a sole pad 141, an inertial sensor 142, and a plurality of pressure sensors 143. The sole pad 141 is connected to the lower end of the calf support 11. An inertial sensor 142 and a plurality of pressure sensors 143 are distributed within the sole pad 141. The inertial sensor 142 is used to detect angular data of the plantar surface of the user's foot and transmit the angular data to the controller 16. The plurality of pressure sensors 143 are configured to sense the pressure experienced by the patient at various locations on the plantar surface of the foot and to transmit pressure data from the plantar surface to the controller 16. Specifically, the accelerometer and gyroscope sensors provided in the inertial sensor 142 can accurately detect the angle of the plantar surface of the user with respect to the ground, i.e., the posture of the plantar surface. The inertial sensor 142 and the pressure sensor 143 are communicatively coupled to the controller 16 to transmit data of the detected plantar surface attitude to the controller 16. The controller 16 analyzes the received angle data and pressure data to identify the plantar surface pose of the patient. The controller 16 is electrically connected to the actuator 15, so as to control the actuator 15 to adjust the amount of rotational damping between the thigh support plate 13 and the knee adapter 12 according to the recognized posture information of the plantar surface of the foot of the user.
Further, a first adjustment strap 18 is removably attached to the calf support 11. The first adjustment strap 18 is used to tether the calf support 11 to the calf. A second adjustment strap 19 is detachably connected to the thigh support plate 13. The second adjustment strap 19 is used to tether the thigh support plate 13 to the thigh. The second adjusting belt 19 is also sleeved with a sleeve gasket 21. The sleeve pad 21 is used to improve the comfort of the patient. In this arrangement, the calf support 11 is restrained to the calf by two first adjustment straps 18, and the thigh support plate 13 is restrained to the thigh by two second adjustment straps 19.
Further, the controller 16 is detachably connected to the thigh support plate 13 via a third adjustment strap 20; the controller 16 is detachably mounted to the third adjusting belt 20. The third adjustment strap 20 may be strapped to the waist of the patient.
Specifically, after the training device is worn by the patient in the sitting position during use, the comfort level is adjusted in the standing position, that is, the first adjustment strap 18 and the second adjustment strap 19 are adjusted, so that the wearable lower limb rehabilitation exercise training device 10 is worn by the patient in a comfortable position. Then, the wearable lower limb rehabilitation exercise training device 10 is started, and at this time, the wearable lower limb rehabilitation exercise training device 10 immediately executes a self-checking program, so as to ensure that the accelerometer, the gyroscope sensor and the actuator 15 in the foot pad assembly 14 can normally work.
When the patient starts walking exercise, the wearable lower limb rehabilitation exercise training device 10 detects gait information of the plantar surface of the foot of the patient through the accelerometer and gyroscope sensors in the inertial sensor 142 and the plurality of pressure sensors 143 in the foot pad assembly 14 and feeds back the detected gait information to the controller 16 in real time. The wearable lower limb rehabilitation exercise trainer 10 can divide the plantar postures into four postures: 1. the toe is upwarped and the sole surface rotates downwards around the heel; 2. the plantar surface is horizontal and static; 3. the sole surface rotates upwards around the toe to raise the heel; 4. the plantar surface moves rapidly and without a close or adjacent center of rotation. The four gait phases divided by the four postures corresponding to the lower limb walking process respectively are as follows: initial support phase (heel strike), full support phase (sole strike), final support phase (toe-joint strike), and swing phase. The foot pad assembly 14 sends the detected plantar surface gait information to the controller 16. The controller 16 controls the actuator 15 to adjust the rotational damping between the thigh support plate 13 and the knee adapter 12 to a corresponding magnitude according to the received plantar gait information, so that the patient can train safely and efficiently. The executing actions of the actuator 15 corresponding to the four gait phases are respectively: when the initial phase is supported, the rotational damping is increased, the falling posture of the patient during walking is judged, and the increase of the rotational damping is beneficial to the standing stability of the patient; when the patient stands in the full-support phase, the patient is judged to be in a standing posture, and the patient stands stably by adjusting the rotary damping to be full damping; when the support is in the final phase, the rotational damping is reduced, the starting posture of the patient in walking is judged, and the reduction of the rotational damping is beneficial to the patient to bend the leg to walk; when the patient is in the swing phase, the patient is judged to be in the walking posture when walking, namely the feet are completely lifted off, and the legs of the patient need to be capable of freely bending, so that the rotation damping is adjusted to be undamped.
Further, the actuator 15 includes: the device comprises a shell 151, a first shaft 152, a second shaft 153, a steering engine 154 for providing rotating force, a driving gear 155, a driven gear 156, a damping adjusting valve 157 and a damping actuator 158; one end of the housing 151 is rotatably connected to the knee adapter 12 by a first shaft 152 and the other end is rotatably connected to the thigh support plate 13 by a second shaft 153; the steering engine 154 is mounted in the housing 151; the driving gear 155 is fixedly connected to the output end of the steering gear 154; the driven gear 156 is fixedly connected to the input end of the damping adjusting valve 157 and meshed with the driving gear 155; the output end of the damping adjusting valve 157 is connected to one end of a damping actuator 158; the other end of the damping actuator 158 is rotatably sleeved on the outer circumference of the second shaft 153. In use, the controller 16 controls the steering engine 154 to rotate according to the received gait information of the plantar surface of the foot. The steering gear 154 drives the driven gear 156 to rotate through the driving gear 155, so that the damping adjusting valve 157 is adjusted through the input end of the damping adjusting valve 157, and the damping of the damping actuator 158 is adjusted. Because the other end of the damping actuator 158 is rotatably sleeved on the periphery of the second shaft 153: when the damping of the damping actuator 158 increases, the damping actuator 158 pushes the thigh support plate 13 through the second shaft 153, so that the second shaft 153 is kept away from the first shaft 152, and the thigh support plate 13 and the knee adapter 12 are difficult to rotate; when the damping of the damping actuator 158 is reduced, the thrust of the damping actuator 158 pushing the thigh support plate 13 through the second shaft 153 is reduced, and at this time, the thigh support plate 13 and the knee adapter 12 can rotate correspondingly according to the magnitude of the rotational damping. The rotational damping between the thigh support plate 13 and the knee adapter 12 decreases in a linear increase.
In summary, the wearable lower limb rehabilitation exercise training device 10 assists the patient to train through the actuator 15, is light in use, long in endurance time, and suitable for being used at ordinary times. The wearable lower limb rehabilitation exercise training device 10 can accurately identify the gait information of the plantar surface of the foot of the patient through the foot pad assembly 14, so that the actuator 15 can be accurately controlled according to the gait information, and the training effect of the wearable lower limb rehabilitation exercise training device 10 on the patient is further improved.
Further, the controller 16 further includes: a status light. The status light is used to display the power level of the controller 16. The status light is electrically connected to the battery of the controller 16. The status light alerts the patient to charge when the battery of the controller 16 is not sufficiently charged.

The encoder 17 is used to detect the rotation angle between the thigh support and the knee adapter 12, so as to obtain the swing angle of the knee joint. An encoder 17 is secured to the knee adapter 12 and is communicatively connected to the controller 16. When a relative rotation occurs between the thigh support and the knee adapter 12, the encoder 17 records the rotation angle therebetween in real time.
Further, the wearable lower limb rehabilitation exercise training device 10 is also provided with a moving end. The mobile terminal is used for recording the training data of the user in real time so as to know the training condition of the user. The mobile end is communicatively coupled to the controller 16.

By the mode, doctors and patients can conveniently check the detailed information of the patients who train by using the wearable lower limb rehabilitation exercise training device 10 at any time, so that doctors and patients can be helped to diagnose and treat.
Further, the mobile terminal can be connected to the controller 16 through bluetooth communication. That is, the controller 16 may transmit the relevant data to the mobile terminal in real time through bluetooth.
