Description

Technical Field

[0001] This utility model relates to a wearable exoskeleton rehabilitation device, belonging to the field of rehabilitation training technology. Background Technology

[0002] For patients with impaired or incomplete lower limb function, rehabilitation training devices are often needed to help them recover faster. Existing rehabilitation training usually involves wearing an exoskeleton. The lower limb exoskeleton, driven by modules or other drive structures, will move the legs to walk or pedal.

[0003] Because the patients' legs are in the recovery period and their leg support is weak, after a period of rehabilitation training, the patients cannot sit and rest because there is no rest area on the training device. They need to be put down from the rehabilitation training device before they can sit on a stool in another location to rest. Therefore, we propose an exoskeleton wearable rehabilitation device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a wearable exoskeleton rehabilitation device, which solves the problem in the prior art that the training device does not have a rest area, so the patient cannot sit and rest and needs to be put down from the rehabilitation training device before sitting on a stool in another location to rest.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0006] A wearable exoskeleton rehabilitation device includes a support frame with vertical grooves on both sides. Threaded rods are installed inside the grooves, and two threaded rods are connected by a pulley assembly. The pulley assembly includes a synchronous pulley, and a synchronous pulley is fixedly installed at the top of the threaded rod. The two synchronous pulleys are connected by a synchronous belt. One of the synchronous pulleys is fixedly installed at the output end of a servo motor. A motor mounting bracket is fixedly installed on the support frame, and the servo motor is fixedly installed on the inner top wall of the motor mounting bracket. A slider is slidably connected inside the grooves, and the threaded rod is threadedly connected inside the slider. A base is mounted on the slider, and a positioning plate is rotatably connected to the base. A connecting rod is fixedly installed on the outer surface of the positioning plate, and a seat plate is fixedly connected to the end of the connecting rod away from the positioning plate.

[0007] By adopting the above technical solution, when the patient needs to rest, the caregiver can rotate the positioning plate 90 degrees to move the seat from the side of the support frame to the front of the support frame. When both seats are rotated to the front of the support frame, the patient can sit directly on the seat to rest. After resting, the patient can continue rehabilitation training. This makes it easier and less strenuous for the caregiver. Furthermore, the rotation of the threaded rod allows the slider to move inside the slide groove, adjusting the height of the slider to adjust the height of the seat, thus meeting the patient's needs for seat height and making sitting more comfortable.

[0008] The present invention is further configured such that: a sunshade is slidably connected inside the seat, and a positioning handle is provided on the seat.

[0009] By adopting the above technical solution, when patients are undergoing rehabilitation training outdoors in bright sunlight, with the seat board positioned on both sides of the support frame, the caregiver can activate the servo motor. The servo motor, through a pulley system, drives two threaded rods, rotating them to the top of the training frame. The positioning plate can then be rotated 90 degrees, positioning the two seat boards in front of the support frame. At this point, the caregiver can loosen the positioning handle to remove the sunshade from inside the seat board, then tighten the handle to lock it in place. Activating the servo motor again controls the threaded rods to rotate, raising the seat board position. The combination of the seat board and sunshade effectively blocks sunlight from above, facilitating outdoor training for the patient.

[0010] The present invention is further configured such that threaded holes are provided on both the chassis and the positioning plate, and a locking handle is threadedly connected to the inside of the positioning plate, with the bottom end of the locking handle extending into the threaded hole on the chassis.

[0011] By adopting the above technical solution, after the positioning disc rotates, the locking handle is screwed into the threaded holes of the positioning disc and the chassis, which can limit the position of the positioning disc and keep it in the required position. In the locked state, the positioning disc and the chassis will not be displaced relative to each other.

[0012] The present invention is further configured such that: a support block is fixedly connected to the lower surface of the support frame, a protective door is hinged to the support block, a bottom frame is fixedly connected to the side of the support block facing the ground, and a roller is installed on the side of the bottom frame facing the ground.

[0013] By adopting the above technical solution, the support block can support the support frame. Due to the action of the rollers, when the patient is undergoing rehabilitation training, the caregiver can push the training equipment to move, allowing the patient to move during the training process.

[0014] The beneficial effects of this utility model are as follows: When the patient needs to rest, the caregiver can rotate the positioning plate 90 degrees to rotate the seat from the side of the support frame to the front of the support frame. When both seats are rotated to the front of the support frame, the patient can sit directly on the seat to rest. After resting, the patient can continue rehabilitation training. This makes it easier and less strenuous for the caregiver. In addition, the rotation of the threaded rod can move the slider inside the slide groove, adjusting the height of the slider, thereby adjusting the height of the seat to meet the patient's needs for seat height. Adjusting the seat to the required height makes sitting more comfortable. Attached Figure Description

Detailed Implementation

[0021] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0022] Example 1

[0023] like Figure 1 , Figure 2 and Figure 5As shown, a wearable exoskeleton rehabilitation device includes a support frame 1. Vertical grooves 2 are provided on both sides of the support frame 1. Threaded rods 3 are installed inside the grooves 2. The two threaded rods 3 are connected by a pulley assembly, which includes a synchronous pulley 14. A synchronous pulley 14 is fixedly installed at the top of the threaded rod 3. The two synchronous pulleys 14 are connected by a synchronous belt 15. One of the synchronous pulleys 14 is fixedly installed at the output end of a servo motor 16. A motor mounting bracket 17 is fixedly installed on the support frame 1. The servo motor 16 is fixedly installed on the inner top wall of the motor mounting bracket 17. A slider 4 is slidably connected inside the grooves 2. The threaded rods 3 are threadedly connected inside the slider 4. Because the synchronous belt 15 and the synchronous pulley 14 have matching teeth, slippage will not occur when the synchronous belt 15 and the synchronous pulley 14 rotate, allowing the two threaded rods 3 to rotate synchronously. This allows simultaneous control of the movement of the two sliders 4 within the grooves 2.

[0024] like Figure 1 and Figure 3 As shown, a base plate 5 is fixedly connected to the end of the slider 4 extending from the slide groove 2. A positioning plate 6 is rotatably connected to the base plate 5. A rotating shaft is installed inside the base plate 5 via a bearing. The end of the rotating shaft away from the base plate 5 is fixedly connected to the positioning plate 6. A connecting rod 7 is fixedly installed on the outer surface of the positioning plate 6. A seat plate 8 is fixedly connected to the end of the connecting rod 7 away from the positioning plate 6. When the patient is performing rehabilitation training, the two seat plates 8 are positioned on both sides of the support frame 1. During the patient's training, the position of the seat plates 8 will not affect the patient's training. When the patient needs to rest... When resting, the caregiver can rotate the positioning plate 6 ninety degrees to move the seat 8 from the side of the support frame 1 to the front of the support frame 1. When both seat 8 are rotated to the front of the support frame 1, the patient can sit directly on the seat 8 to rest. After resting, the patient can continue rehabilitation training. This makes it easier and less strenuous for the caregiver. In addition, the rotation of the threaded rod 3 can move the slider 4 inside the slide groove 2. Adjusting the height of the slider 4 can adjust the height of the seat 8, thereby meeting the patient's needs for the height of the seat 8. Adjusting the seat 8 to the required height makes sitting more comfortable.

[0025] like Figure 3As shown, a sunshade 9 is slidably connected inside the seat 8. A positioning handle 10 is provided on the seat 8. A positioning hole is opened on the side of the sunshade 9. A threaded positioning pin is installed on the positioning handle 10. When limiting the sunshade 9, turning the positioning handle 10 will cause the threaded positioning pin on the positioning handle 10 to pass through the seat 8 and move into the positioning hole on the sunshade 9, thus blocking and limiting the sunshade 9 and keeping it stable. When the patient is doing rehabilitation training outdoors and the sunlight is glaring, the caregiver can activate the servo motor when the seat 8 is held on both sides of the support frame 1. The servo motor 16, through the transmission of the pulley group, can drive the two threaded rods 3. After rotating to the top of the training frame, the positioning plate 6 can be rotated 90 degrees, and the two seat plates 8 can be rotated to the front of the support frame 1. At this time, with the help of the caregiver, the positioning handle 10 can be loosened to pull the sunshade 9 out of the seat plate 8. Then, the positioning handle 10 is tightened to lock it. The servo motor 16 is started again to control the rotation of the threaded rods 3, and the position of the seat plate 8 is adjusted to be higher. The combination of the seat plate 8 and the sunshade 9 can block the sun from above the patient, effectively achieving the sunshade effect and helping the patient to train outdoors.

[0026] like Figure 2 and Figure 4 As shown, both the chassis 5 and the positioning plate 6 have threaded holes 11. The positioning plate 6 is internally threaded with a locking handle 12, and the bottom end of the locking handle 12 extends into the threaded hole 11 on the chassis 5. The locking handle 12 is equipped with a locking pin. When the positioning plate 6 is rotated to the desired position, the caregiver loosens the locking handle 12, which allows the locking pin on the locking handle 12 to first enter the threaded hole 11 on the positioning plate 6, and then enter the threaded hole 11 on the chassis 5. This allows the positioning plate 6 to be positioned and kept in the desired position. In the locked state, the positioning plate 6 and the chassis 5 will not undergo relative displacement.

[0027] like Figure 2 As shown, a support block 18 is fixedly connected to the lower surface of the support frame 1. A protective door 19 is hinged to the support block 18. A battery pack is installed inside the support block 18, providing an installation position for the battery pack and supporting the support frame 1. The battery pack is electrically connected to the servo motor 16 through wires, providing power to the servo motor 16 and the exoskeleton module. The protective door 19 can shield and protect the battery pack, effectively preventing it from being bumped. A base frame 20 is fixedly connected to the side of the support block 18 facing the ground. A roller 13 is installed on the side of the base frame 20 facing the ground. Due to the function of the roller 13, the caregiver can push the training device to move during the patient's rehabilitation training, allowing the patient to move during the training process.

[0028] When the patient is training, the two seat boards 8 are positioned on either side of the support frame 1. When the patient needs to rest, the caregiver can rotate the positioning plate 6 90 degrees to move the seat boards 8 from the side of the support frame 1 to the front. When both seat boards 8 are in front of the support frame 1, the patient can sit directly on the seat boards 8 to rest. When the patient is doing rehabilitation training outdoors and the sunlight is glaring, while the seat boards 8 are on either side of the support frame 1, the caregiver can start the servo motor 16. The servo motor 16, through the transmission of the pulley group, can drive the two threaded rods 3. After rotating them to the top of the training frame, the positioning plate 6 can be rotated 90 degrees to move the two seat boards 8 to the front of the support frame 1. At this time, the caregiver can loosen the positioning handle 10 to pull the sunshade 9 out of the seat board 8, and then tighten the positioning handle 10 to lock it. The servo motor 16 is started again to control the rotation of the threaded rods 3, raising the position of the seat boards 8. The combination of the seat boards 8 and the sunshade 9 can then provide shade for the patient.
