Technical Field

[0001] This utility model relates to the field of rehabilitation training technology, specifically a lower limb nerve rehabilitation training device. Background Technology

[0002] Lower limb nerve rehabilitation training equipment is typically designed for patients with lower limb dysfunction caused by neurological diseases, injuries, or surgeries. This type of equipment aims to help patients restore nerve function, muscle strength, and joint mobility in their lower limbs through scientific exercise training, thereby improving their quality of life. In active training mode, patients need to exert their own efforts to drive the movement of the affected limb.

[0003] Patients who have undergone knee replacement surgery need to relearn how to walk correctly and stably using their new artificial joint. In order to recover as soon as possible, family members often force patients to practice walking before they are able to stand independently. This not only fails to achieve the goal, but can also cause damage to the knee joint. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a lower limb nerve rehabilitation training device, including a base plate, on which a lifting chair and a training mechanism are provided. The training mechanism includes a fixed cover, and an installation plate is installed in the middle section of the inner arc wall of the fixed cover. A rotating shaft is rotatably connected to the center of the installation plate. L-shaped rotating rods are connected to both sides of the rotating shaft. The L-shaped rotating rods include a horizontal bar and a vertical bar that is vertically arranged away from the L-shaped rotating rod. Foot pedals are rotatably connected to the side of the two vertical bars away from the rotating shaft. A magnetic suction pad is magnetically connected above the foot pedals. A pressure sensor and a fixing sleeve are installed on the magnetic suction pad. The pressure sensor is located at the bottom of the fixing sleeve. A fixing strap is installed above the fixing sleeve, and one end of the fixing strap is connected to a Velcro strap.

[0006] Furthermore, a gear one is fitted on the outer arc wall of one of the rotating shafts, and gear one meshes with gear two.

[0007] Furthermore, the bottom of the base plate is equipped with casters, a handle is installed on the side of the base plate near the lifting chair, and a base is fixedly connected to the bottom of the outer arc wall of the fixed cover.

[0008] Furthermore, the base plate has threaded grooves on two opposite sides away from the lifting chair and the fixed cover, and on the side close to the lifting chair. A threaded rod is threadedly connected in the threaded groove. A rotating handle is installed above the threaded rod, and a suction cup is installed below the threaded rod.

[0009] Furthermore, the lifting chair has two support legs slidably connected to both sides. The bottom of the lifting chair is fixedly connected to a hydraulic rod, and the bottom end of the hydraulic rod is fixedly connected to the base plate. The support legs have vertical grooves, and the side walls of the lifting chair are fixedly connected to sliders corresponding to the grooves. The lifting chair can move vertically within the grooves by sliding the sliders.

[0010] Furthermore, the fixed sleeve is L-shaped, with both its vertical and horizontal ends being semi-circular tubular structures.

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] See Figure 1-4 As shown, a lower limb nerve rehabilitation training device includes a base plate 1, a lifting chair 3 and a training mechanism on the base plate 1. The training mechanism includes a fixed cover 11, an installation plate 22 installed in the middle of the inner arc wall of the fixed cover 11, a rotating shaft 16 rotatably connected to the center of the installation plate 22, and L-shaped rotating rods 15 connected to both sides of the rotating shaft 16. The L-shaped rotating rods 15 include a horizontal bar and a vertical bar that is vertically arranged away from the L-shaped rotating rods 15. Foot pedals 13 are rotatably connected to the side of the two vertical bars away from the rotating shaft 16. A magnetic suction pad 14 is magnetically connected above the foot pedals 13. A pressure sensor 24 and a fixing sleeve 25 are installed on the magnetic suction pad 14. The pressure sensor 24 is located at the bottom of the fixing sleeve 25. A fixing strap 26 is installed above the fixing sleeve 25. One end of the fixing strap 26 is connected to a Velcro 27.

[0024] In the specific implementation process, the fixed cover 11 is a circular tube structure with its opening located on the horizontal plane, used to accommodate and support the user's lower limbs while limiting their range of motion to ensure the accuracy and safety of training movements. The fixed cover 11 is located on the side away from the lifting chair 3. The mounting plate 22 serves as the mounting base for the rotating shaft 16. The rotating shaft 16 is connected to the bearing so that it can rotate stably, driving the L-shaped rotating rod 15 connected to it to move. The rotating shaft 16 allows the L-shaped rotating rod 15 to rotate freely within a certain range, simulating the movement trajectory of the legs. The L-shaped rotating rod 15 is rotatably connected to the foot pedal 13 through the bearing, allowing the foot pedal 13 to perform compound movements in the horizontal and vertical planes, which is closer to the natural gait. The user places their feet on the foot pedal 13 and uses the L-shaped rotating rod 15 to drive the foot pedal 13 for rehabilitation training.

[0025] An electromagnet is installed inside the magnetic pad 14, and the foot pedal 13 is made of iron. A pressure sensor 24 and a fixing sleeve 25 are installed on the magnetic pad 14 to monitor the user's foot pressure and fix the user's foot through the fixing sleeve 25. The fixing strap 26 tightly connects the user's ankle to the fixing sleeve 25 through Velcro 27. This design not only improves the user's stability during training, but also prevents the foot from slipping or falling off during exercise.

[0026] The pressure sensor 24 is used to monitor the pressure applied by the user's feet to the pedal 13 in real time. By collecting and analyzing this data, the user's training effect can be evaluated and adjustments can be made as needed.

[0027] It should be noted that the center of the mounting plate 22 has a hole that matches the diameter of the rotating shaft 16. This hole is used to install the bearing. The inner ring of the bearing is pressed onto the journal of the rotating shaft 16 to ensure that the inner ring and the journal fit tightly without gaps. The outer ring of the bearing is installed into the hole of the mounting plate 22, and the bearing cap is used to fix the outer ring of the bearing on the mounting plate to ensure that the bearing will not fall off the mounting plate and to allow the rotating shaft 16 to rotate freely in the bearing.

[0028] It should be noted that the pedal 13 has an axle at the horizontal center position, and a hole matching the axle of the pedal 13 is opened at the corresponding position of the vertical rod. This hole is used to install a bearing. Aligning the axle of the pedal 13 with the outer ring of the bearing ensures that the pedal 13 can rotate freely around the vertical rod.

[0029] See Figure 1-4 As shown, a lower limb nerve rehabilitation training device includes a gear 17 mounted on the outer arc wall of a rotating shaft 16. The gear 17 is meshed with a gear 28. A connecting strip 21 is installed on the inner arc wall of a fixed cover 11 near the gear 17. One end of the connecting strip 21 is connected to a geared motor box 19. A geared motor 20 is installed inside the geared motor box 19. The drive shaft of the geared motor 20 is connected to the gear 28.

[0030] In the specific implementation process, the geared motor 20 is installed in the geared motor box 19, and its transmission shaft is connected to the gear 18. When the geared motor 20 starts, its power is transmitted to the gear 18 through the transmission shaft. Since the gear 17 meshes with the gear 18, the gear 17 will also rotate. The rotating shaft 16 will rotate with the rotation of the gear 17, thereby driving the L-shaped rotating rod 15 connected to the rotating shaft 16 to move.

[0031] It should be noted that the connecting strip 21 and the geared motor box 19 are fixedly connected by bolts, and the connecting strip 21 is fixed to the fixing cover 11 by welding. The gear 2 18 is fixedly connected to a rotating shaft, and the rotating shaft is fitted with a bearing. It is rotatably connected to the mounting plate 22, and the rotating shaft and gear 2 18 are driven to rotate by the geared motor 20.

[0032] See Figure 1-4 As shown, a lower limb nerve rehabilitation training device has casters 8 installed at the bottom of the base plate 1, a handle 5 installed on the side of the base plate 1 near the lifting chair 3, and a base 12 fixedly connected to the bottom end of the outer arc wall of the fixed cover 11.

[0033] In practice, the casters 8 installed at the bottom of the base plate 1 make the whole equipment highly mobile. Medical staff or patients' families can easily push the equipment with the handle 5 to move it to the required location, such as wards, rehabilitation rooms or outdoors, which greatly improves the flexibility of use.

[0034] The bottom end of the outer arc wall of the fixed cover 11 is securely connected to the base plate via the base 12, which enhances its stability.

[0035] See Figure 1-4 As shown, a lower limb nerve rehabilitation training device has threaded grooves on two opposite sides of the base plate 1 away from the lifting chair 3 and the fixed cover 11, and on the side close to the lifting chair 3. A threaded rod 7 is threadedly connected in the threaded groove. A rotating handle 6 is installed above the threaded rod 7, and a suction cup 23 is installed below the threaded rod 7.

[0036] In practical implementation, the threaded groove design on the base plate 1 allows the threaded rod 7 to move up and down by rotation. When the equipment needs to be fixed in a certain position for rehabilitation training, the operator can drive the threaded rod 7 downward by rotating the handle 6 until the suction cup 23 is in close contact with the ground and generates sufficient suction. The rehabilitation training equipment can increase its stability through the adhesion between the suction cup 23 and the ground, preventing it from moving or tipping over due to external forces during training. When it is necessary to move the equipment or conduct rehabilitation training in different locations, the operator only needs to rotate the handle 6 in the opposite direction to easily lift the threaded rod 7 and the suction cup 23 from the ground, realizing the quick disassembly and movement of the equipment. This design greatly improves the portability and flexibility of the equipment.

[0037] See Figure 1-4 As shown, a lower limb nerve rehabilitation training device includes a lifting chair 3 with two supporting legs 2 slidably connected to both sides. The number of supporting legs 2 on the same side is two. A hydraulic rod 9 is fixedly connected to the bottom of the lifting chair 3, and the bottom end of the hydraulic rod 9 is fixedly connected to the base plate 1. The supporting legs 2 have vertical grooves. A slider corresponding to the groove is fixedly connected to the side wall of the lifting chair 3. The lifting chair 3 can move vertically in the groove by the slider.

[0038] In the specific implementation process, support legs 2 are slidably connected to both sides of the lifting chair 3, so that the lifting chair 3 can move relative to the support legs 2 in the vertical direction. The vertical groove opened on the support legs 2 matches the slider fixedly connected to the side wall of the lifting chair 3. By sliding the slider in the groove, the lifting chair 3 can achieve the lifting function. The hydraulic rod 9 fixedly connected to the bottom of the lifting chair 3 is the key component for driving the lifting chair 3 to rise and fall. The bottom end of the hydraulic rod 9 is fixedly connected to the base plate 1, ensuring that the hydraulic rod 9 can stably provide power during the driving process. When the hydraulic rod 9 extends or shortens, it will push or pull the lifting chair 3 to rise or fall.

[0039] See Figure 1-4 As shown, a lower limb nerve rehabilitation training device has a fixed sleeve 25 in the shape of an L, with both its vertical and horizontal ends being semi-arc-shaped circular tube structures.

[0040] In practice, the patient can insert their foot into the horizontal end of the fixation sleeve 25. The horizontal end is a semi-circular tube structure whose shape corresponds to the foot, and the vertical end corresponds to the ankle. The ankle, which is bound by the fixation strap 26, can be fixed to the fixation sleeve 25 by Velcro 27.

[0041] See Figure 1-4 As shown, a lower limb nerve rehabilitation training device has two support legs 2 located on the same side, each with a handrail 4 connected to its top. A PLC controller 10 is installed on one of the handrails 4. The signal output terminal of the PLC controller 10 is electrically connected to the signal input terminal of the hydraulic rod 9, the geared motor 20, and the pressure sensor 24.

[0042] In practical implementation, the handrail 4 not only provides support and stability for the patient during training, but also serves as the mounting location for the PLC controller 10. This design allows operators or patients to easily access the PLC controller 10 for necessary settings or adjustments. By controlling the extension or retraction of the hydraulic rod 9 through the PLC controller 10, the height of the lifting chair 3 can be precisely adjusted to meet the rehabilitation needs of different patients. By controlling the speed and direction of the geared motor 20 through the PLC controller 10, the intensity of rehabilitation training can be adjusted. (Pressure sensor...) Pressure sensor 24 is used to monitor the contact pressure between the patient and the equipment in real time. By electrically connecting the output of pressure sensor 24 to the input of PLC controller 10, PLC controller 10 can acquire pressure data in real time and make judgments and processes according to preset safety thresholds to ensure the safety of the patient during training. When pressure sensor 24 does not receive pressure, geared motor 20 will automatically turn off the power. PLC controller 10 can also control the electrical properties of electromagnets in magnetic pad 14. After training is completed, the patient can easily remove their foot from the fixing sleeve 25 by controlling the magnetic pad 14 to turn off the power.

[0043] Working principle:

[0044] Step 1: The gear motor 20 drives gear 17 and gear 18 to rotate the shaft 16 and L-shaped rotating rod 15, thereby driving the foot pedal 13 to move, simulating the movement trajectory of the leg to achieve rehabilitation training. The pressure sensor 24 monitors the pressure applied by the user's foot to the foot pedal 13 in real time, collects and analyzes the data to evaluate the training effect, and makes adjustments as needed. The fixing strap 26 on the fixing sleeve 25 is used to tightly connect the user's ankle to the fixing sleeve 25 with Velcro 27 to prevent the foot from slipping or falling off during exercise.

[0045] Step 2: The height of the lifting chair 3 is adjusted by the hydraulic rod 9 to meet the rehabilitation needs of different patients. The casters 8 and suction cups 23 installed at the bottom of the equipment facilitate the movement and fixation of the entire device. At the same time, the PLC controller 10 controls the geared motor 20, hydraulic rod 9, pressure sensor 24 and magnetic pad 14 to ensure safety and stability during the training process.
